make, pick up o Punt on write errors - ENOSPC etc. 2021-10-22 Simon J Gerraty * configure.in: use_defshell, set both DEFSHELL_INDEX and defshell_path if appropriate. This makes it easier to use say the KSH specification with and alternate path for the shell. * configure.in compat.c: for SCO we need to force UseShell * configure.in: SCO /bin/sh is not usable, provide a list of alternatives for use as .SHELL. We still have to mark some tests as broken, plus more if we end up with ksh as .SHELL. Issue a warning about skipped tests. * boot-strap: leave TOOL_DIFF to configure * configure.in: on SCO native cc is not usable, gcc is to be found in /usr/gnu/bin and while ancient is at least able to compile bmake. Thus we add /usr/gnu/bin to PATH if it exists, and later check if $CC would have been found via $PATH. If not we set CC to the full path of $CC. Also gnu diff is known to support -u, so if it exists use it. * configure.in: move getopt to AC_REPLACE_FUNCS also add AC_C_INLINE - in an attempt to compile using native cc on SCO. * configure.in: check for stresep as well as strsep, since we define the later to the former if necessary, and if we have to provide stresep we also need to provide a prototype. * configure.in: we no longer need to worry about sys/cdefs.h providing __RCSID which simplifies things quite a bit. * make.h: make sure we have __RCSID * unit-tests/Makefile.config.in: add TOOL_DIFF so configure can control it. 2021-10-20 Simon J Gerraty * VERSION: 20211020 Merge with NetBSD make, pick up o confirm sync of unit-tests 2021-10-18 Simon J Gerraty * configure.in: check if timezone Europe/Berlin is supported if not try UTC-1 * configure.in: if .OBJDIR is $srcdir/obj we need to create a symlink unit-tests -> ../unit-tests/obj so that unit-tests/Makefile.config is put in the right place. * refine filtering of .OBJDIR in unit-tests 2021-10-16 Simon J Gerraty * Fix unit-tests on Minix 3.2.0 o job.c: do not punt if read of token pipe fails for EAGAIN. On Minix at least, we are not ready to read the childExitJob pipe when poll says we are. There should actually be no reason for this pipe to be non-blocking, but while that works fine on {Net,Free}BSD it breaks another test case on Minix. o unit-tests/Makefile: deal with variants of error messages and use of obj as .OBJDIR 2021-10-14 Simon J Gerraty * configure.in: add sigaction to AC_REPLACE_FUNCS we also need to check for sigaddset etc just for the benefit of sigact.c * Add sigact.c as sigaction.c so this "just works". This should have been done back when bmake_signal started using sigaction (I only just noticed that sigact.c wasn't here ;-) Note: I no longer have access to any system where this would matter.

Gerraty * Makefile.in (accept test): use ${.MAKE:S,^./,${.CURDIR}/,} so that './bmake -f Makefile test' works. 2004-02-14 Simon J. Gerraty * Makefile.in: (BMAKE_VERSION): bump to 20040214 * Merge with NetBSD make, pick up: o search upwards for *.mk o fix for double free of var substitution buffers o use of getopt replaced with custom code, since the usage (re-scanning) isn't posix compatible. 2004-02-12 Simon J. Gerraty * arch.c: don't include ranlib.h on ELF systems (thanks to Chuck Cranor ). 2004-01-18 Simon J. Gerraty * Makefile.in (BMAKE_VERSION): bump to 20040118 * boot-strap (while): export vars we assign to on cmdline * unit-test/Makefile.in: ternary is .PHONY 2004-01-08 Simon J.

Gerraty * Make portable snprintf safer - output to /dev/null first to check space needed. * Makefile.in (BMAKE_VERSION): bump version to 20031222 * Merge with NetBSD make, pick up: o -dg3 to show input graph when things go wrong. o explicitly look for makefiles in objdir if not found in curdir so that errors in .depend etc will be reported accurarely. o avoid use of -e in shell scripts in jobs mode, use '|| exit $?' instead as it more accurately reflects the expected behavior and is more consistently implemented. o avoid use of asprintf. 2003-09-28 Simon J. Gerraty * util.c: Add asprintf and vasprintf. * Makefile.in (BMAKE_VERSION): bump version to 20030928 * Merge with NetBSD make, pick up: :[] modifier - allows picking words from a variable. :tW modifier - allows treating value as one big word.

Also compat mode now uses the same shell specs. 2003-07-29 Simon J. Gerraty * var.c (Var_Parse): ensure delim is initialized. * unit-tests/Makefile.in: use single quotes to avoid problems from some shells. * makefile.boot.in: Run the unit-tests as part of the bootstrap procedure. 2003-07-28 Simon J. Gerraty * unit-tests/Makefile.in: always force complaints from ${TEST_MAKE} to be from 'make'. * configure.in: add check for 'diff -u' also fix some old autoconf'isms * Makefile.in (BMAKE_VERSION): bump version to 20030728. if using GCC add -Wno-cast-qual to CFLAGS for var.o * Merge with NetBSD make Pick up fix for :ts parsing error in some cases.

Gerraty * Merge with NetBSD make Pick up fix for ParseDoSpecialSrc - we only use it if .WAIT appears in src list. 2003-03-21 Simon J. Gerraty * Merge with NetBSD make (mmm 10th anniversary!) pick up fix for .WAIT in srcs that refer to $@ or $* (PR#20828) pick up -X which tells us to not export VAR=val via setenv if we are already doing so via MAKEFLAGS. This saves valuable env space on systems like Darwin. set MAKE_VERSION to 3.1.17 * parse.c: pix up fix for suffix rules 2003-03-06 Simon J. Gerraty * Merge with NetBSD make. pick up fix for propagating -B via MAKEFLAGS. set MAKE_VERSION to 3.1.16 * Apply some patches from pkgsrc-bootstrap/bmake Originally by Grant Beattie I may have missed some - since they are based on bmake-3.1.12 2002-12-03 Simon J. Gerraty * makefile.boot.in (bmake): update install targets for those that use them, also clear MAKEFLAGS when invoking bmake.boot to avoid havoc from gmake -w. Thanks to Harlan Stenn . * bmake.cat1: update the pre-formatted man page! 2002-11-30 Simon J. Gerraty * Merge with NetBSD make. pick up fix for premature free of pointer used in call to Dir_InitCur(). set MAKE_VERSION to 3.1.15 2002-11-26 Simon J. Gerraty * configure.in: determine suitable value for MKSRC. override using --with-mksrc=PATH. * machine.sh: use `uname -p` for MACHINE_ARCH on modern SunOS systems. configs(8) will use 'sun4' as an alias for 'sparc'. 2002-11-25 Simon J. Gerraty * Merge with NetBSD make. pick up ${.PATH} pick up fix for finding ../cat.c via .PATH when .CURDIR=.. set MAKE_VERSION to 3.1.14 add configure checks for killpg and sys/socket.h 2002-09-16 Simon J. Gerraty * tag bmake-3-1-13 * makefile.boot.in (bmake): use install-mk Also setup ./mk before trying to invoke bmake.boot incase we needed install-mk to create a sys.mk for us. * configure.in: If we need to add -I${srcdir}/missing, make it an absolute path so that it works for lst.lib too. * make.h: always include sys/cdefs.h since we provide one if the host does not. * Makefile.in (install-mk): use MKSRC/install-mk which will do the right thing. use uname -p for ARCH if possible. since install-mk will setup links bsd.prog.mk -> prog.mk if needed, just .include bsd.prog.mk * Merge with NetBSD make (NetBSD-1.6) Code is ansi-C only now. Bug in handling of dotLast is fixed. Can now assign .OBJDIR and make will reset its notions of life. New modifiers :tu :tl for toUpper and toLower. Tue Oct 16 12:18:42 2001 Simon J. Gerraty * Merge with NetBSD make pick up fix for .END failure in compat mode. pick up fix for extra va_end() in ParseVErrorInternal. Thu Oct 11 13:20:06 2001 Simon J. Gerraty * configure.in: for systems that have sys/cdefs.h check if it is compatible. If not, include the one under missing, but tell it to include the native one too - necessary on Linux. * missing/sys/cdefs.h: if NEED_HOST_CDEFS_H is defined, use include_next (for gcc) to get the native sys/cdefs.h Tue Aug 21 02:29:34 2001 Simon J. Gerraty * job.c (JobFinish): Fix an earlier merge bug that resulted in leaking descriptors when using -jN. * job.c (JobPrintCommand): See if "curdir" exists before attempting to chdir(). Doing the chdir directly in make (when in compat mode) fails silently, so let the -jN version do the same. This can happen when building kernels in an object tree and playing clever games to reset .CURDIR. * Merged with NetBSD make pick up .USEBEFORE Tue Jun 26 23:45:11 2001 Simon J. Gerraty * makefile.boot.in: Give bmake.boot a MAKESYSPATH that might work. Tue Jun 12 16:48:57 2001 Simon J. Gerraty * var.c (Var_Set): Add 4th (flags) arg so VarLoopExpand can tell us not to export the iterator variable when using VAR_CMD context. Sun Jun 10 21:55:21 2001 Simon J. Gerraty * job.c (Job_CatchChildren): don't call Job_CatchOutput() here, its the wrong "fix". Sat Jun 9 00:11:24 2001 Simon J. Gerraty * Redesigned export of VAR_CMD's via MAKEFLAGS. We now simply append the variable names to .MAKEOVERRIDES, and handle duplicate suppression and quoting in ExportMAKEFLAGS using: ${.MAKEOVERRIDES:O:u:@v@$v=${$v:Q}@} Apart from fixing quoting bugs in previous version, this allows us to export vars to the environment by simply doing: .MAKEOVERRIDES+= PATH Merged again with NetBSD make, but the above is the only change. * configure.in: added --disable-pwd-override disable $PWD overriding getcwd() --disable-check-make-chdir disable make trying to guess when it should automatically cd ${.CURDIR} * Merge with NetBSD make, changes include: parse.c (ParseDoDependency): Spot that the syntax error is caused by an unresolved cvs/rcs conflict and say so. var.c: most of Var* functions now take a ctxt as 1st arg. now does variable substituion on rhs of sysv style modifiers. * var.c (Var_Set): exporting of command line variables (VAR_CMD) is now done here. We append the name='value' to .MAKEOVERRIDES rather than directly into MAKEFLAGS as this allows a Makefile to use .MAKEOVERRIDES= to disable this behaviour. GNU make uses a very similar mechanism. Note that in adding name='value' to .MAKEOVERRIDES we do the moral equivalent of: .MAKEOVERRIDES:= ${.MAKEOVERRIDES:Nname=*} name='val' Fri Jun 1 14:08:02 2001 Simon J. Gerraty * make-conf.h (USE_IOVEC): make it conditional on HAVE_SYS_UIO_H * Merged with NetBSD make make -dx can now be used to run commands via sh -x better error messages on exec failures. Thu May 31 01:44:54 2001 Simon J. Gerraty * Makefile.in (main.o): depends on ${SRCS} ${MAKEFILE} so that MAKE_VERSION gets updated. Also don't use ?= for MAKE_VERSION, MACHINE etc otherwise they propagate from the previous bmake. * configure.in (machine): allow --with-machine=generic to make configure use machine.sh to set MACHINE. * job.c (JobInterrupt): convert to using WAIT_T and friends. * Makefile.in: mention in bmake.1 that we use autoconf. * make.1: mention MAKE_PRINT_VAR_ON_ERROR. Wed May 30 23:17:18 2001 Simon J. Gerraty * main.c (ReadMakefile): don't set MAKEFILE if reading ".depend" as that rather defeats the usefulness of ${MAKEFILE}. * main.c (MainParseArgs): append command line variable assignments to MAKEFLAGS so that they get propagated to child make's. Apparently this is required POSIX behaviour? Its useful anyway. Tue May 29 02:20:07 2001 Simon J. Gerraty * compat.c (CompatRunCommand): don't use perror() since stdio may cause problems in child of vfork(). * compat.c, main.c: Call PrintOnError() when we are going to bail. This routine prints out the .curdir where we stopped and will also display any vars listed in ${MAKE_PRINT_VAR_ON_ERROR}. * main.c: add ${.newline} to hold a "\n" - sometimes handy in :@ expansion. * var.c: VarLoopExpand: ignore addSpace if a \n is present. * Added RCSid's for the files we've touched. Thu May 24 15:41:37 2001 Simon J. Gerraty * configure.in: Thanks to some clues from mdb@juniper.net, added autoconf magic to control setting of MACHINE, MACHINE_ARCH as well as what ends up in _PATH_DEFSYSPATH. We now have: --with-machine=MACHINE explicitly set MACHINE --with-force-machine=MACHINE set FORCE_MACHINE --with-machine_arch=MACHINE_ARCH explicitly set MACHINE_ARCH --with-default-sys-path=PATH:DIR:LIST use an explicit _PATH_DEFSYSPATH --with-prefix-sys-path=PATH:DIR:LIST prefix _PATH_PREFIX_SYSPATH --with-path-objdirprefix=PATH override _PATH_OBJDIRPREFIX If _PATH_OBJDIRPREFIX is set to "no" we won't define it. * makefile: added a pathetically simple makefile to drive bootstrapping. Running configure by hand is more useful. * Makefile.in: added MAKE_VERSION, and reworked things to be less dependent on NetBSD bsd.*.mk * pathnames.h: allow NO_PATH_OBJDIRPREFIX to stop us defining _PATH_OBJDIRPREFIX for those that don't want a default. construct _PATH_DEFSYSPATH from the info we get from configure. * main.c: allow for no _PATH_OBJDIRPREFIX, set ${MAKE_VERSION} if MAKE_VERSION is defined. * compat.c: when we bail, print out the .CURDIR we were in. Sat May 12 00:34:12 2001 Simon J. Gerraty * Merged with NetBSD make * var.c: fixed a bug in the handling of the modifier :P if the node as found but the path was null, we segfault trying to duplicate it. Mon Mar 5 16:20:33 2001 Simon J. Gerraty * Merged with NetBSD make * make.c: Make_OODate's test for a library out of date was using cmtime where it should have used mtime (my bug). * compat.c: Use perror() to tell us what really went wrong when we cannot exec a command. Fri Dec 15 10:11:08 2000 Simon J. Gerraty * Merged with NetBSD make Sat Jun 10 10:11:08 2000 Simon J. Gerraty * Merged with NetBSD make Thu Jun 1 10:11:08 2000 Simon J. Gerraty * Merged with NetBSD make Tue May 30 10:11:08 2000 Simon J. Gerraty * Merged with NetBSD make Thu Apr 27 00:07:47 2000 Simon J. Gerraty * util.c: don't provide signal() since we use sigcompat.c * Makefile.in: added a build target. * var.c (Var_Parse): added ODE modifiers :U, :D, :L, :P, :@ and :! These allow some quite clever magic. * main.c (main): added support for getenv(MAKESYSPATH). Mon Apr 2 16:25:13 2000 Simon J. Gerraty * Disable $PWD overriding getcwd() if MAKEOBJDIRPREFIX is set. This avoids objdir having a different value depending on how a directory was reached (via command line, or subdir.mk). * If FORCE_MACHINE is defined, ignore getenv("MACHINE"). Mon Apr 2 23:15:31 2000 Simon J. Gerraty * Do a chdir(${.CURDIR}) before invoking ${.MAKE} or ${.MAKE:T} if MAKEOBJDIRPREFIX is set and NOCHECKMAKECHDIR is not. I've been testing this in NetBSD's make for some weeks. * Turn Makefile into Makefile.in and make it useful. Tue Feb 29 22:08:00 2000 Simon J. Gerraty * Imported NetBSD's -current make(1) and resolve conflicts. * Applied autoconf patches from bmake v2 * Imported clean code base from NetBSD-1.0 diff --git a/contrib/bmake/VERSION b/contrib/bmake/VERSION index f82791fcbac8..0cc67de7b22d 100644 --- a/contrib/bmake/VERSION +++ b/contrib/bmake/VERSION @@ -1,2 +1,2 @@ # keep this compatible with sh and make -_MAKE_VERSION=20230622 +_MAKE_VERSION=20230909 diff --git a/contrib/bmake/bmake.1 b/contrib/bmake/bmake.1 index bfa0f2d74d0a..a658eab6700e 100644 --- a/contrib/bmake/bmake.1 +++ b/contrib/bmake/bmake.1 @@ -1,2754 +1,2770 @@ -.\" $NetBSD: make.1,v 1.366 2023/05/10 18:22:33 sjg Exp $ +.\" $NetBSD: make.1,v 1.371 2023/09/10 21:52:36 rillig Exp $ .\" .\" Copyright (c) 1990, 1993 .\" The Regents of the University of California.

Its input is a list of specifications as to the files upon which programs and other files depend. If no .Fl f Ar makefile option is given, .Nm tries to open .Sq Pa makefile then .Sq Pa Makefile in order to find the specifications. If the file .Sq Pa .depend exists, it is read, see .Xr mkdep 1 . .Pp This manual page is intended as a reference document only. For a more thorough description of .Nm and makefiles, please refer to .%T "PMake \- A Tutorial" (from 1993). .Pp .Nm prepends the contents of the .Ev MAKEFLAGS environment variable to the command line arguments before parsing them. .Pp The options are as follows: .Bl -tag -width Ds .It Fl B Try to be backwards compatible by executing a single shell per command and by making the sources of a dependency line in sequence. .It Fl C Ar directory Change to .Ar directory before reading the makefiles or doing anything else. If multiple .Fl C options are specified, each is interpreted relative to the previous one: .Fl C Pa / Fl C Pa etc is equivalent to .Fl C Pa /etc . .It Fl D Ar variable Define .Ar variable to be 1, in the global scope. .It Fl d Oo Cm \- Oc Ns Ar flags Turn on debugging, and specify which portions of .Nm are to print debugging information. Unless the flags are preceded by .Ql \- , they are added to the .Ev MAKEFLAGS environment variable and are passed on to any child make processes. By default, debugging information is printed to standard error, but this can be changed using the .Cm F debugging flag. The debugging output is always unbuffered; in addition, if debugging is enabled but debugging output is not directed to standard output, the standard output is line buffered. The available .Ar flags are: .Bl -tag -width Ds .It Cm A Print all possible debugging information; equivalent to specifying all of the debugging flags. .It Cm a Print debugging information about archive searching and caching. .It Cm C Print debugging information about the current working directory. .It Cm c Print debugging information about conditional evaluation. .It Cm d Print debugging information about directory searching and caching. .It Cm e Print debugging information about failed commands and targets. .It Cm F Ns Oo Cm \&+ Oc Ns Ar filename Specify where debugging output is written. This must be the last flag, because it consumes the remainder of the argument. If the character immediately after the .Cm F flag is .Ql \&+ , the file is opened in append mode; otherwise the file is overwritten. If the file name is .Ql stdout or .Ql stderr , debugging output is written to the standard output or standard error output respectively (and the .Ql \&+ option has no effect). Otherwise, the output is written to the named file. If the file name ends with .Ql .%d , the .Ql %d is replaced by the pid. .It Cm f Print debugging information about loop evaluation. .It Cm g1 Print the input graph before making anything. .It Cm g2 Print the input graph after making everything, or before exiting on error. .It Cm g3 Print the input graph before exiting on error. .It Cm h Print debugging information about hash table operations. .It Cm j Print debugging information about running multiple shells. .It Cm L Turn on lint checks. This throws errors for variable assignments that do not parse correctly, at the time of assignment, so the file and line number are available. .It Cm l Print commands in Makefiles regardless of whether or not they are prefixed by .Ql @ or other .Dq quiet flags. Also known as .Dq loud behavior. .It Cm M Print debugging information about .Dq meta mode decisions about targets. .It Cm m Print debugging information about making targets, including modification dates. .It Cm n Don't delete the temporary command scripts created when running commands. These temporary scripts are created in the directory referred to by the .Ev TMPDIR environment variable, or in .Pa /tmp if .Ev TMPDIR is unset or set to the empty string. The temporary scripts are created by .Xr mkstemp 3 , and have names of the form .Pa makeXXXXXX . .Em NOTE : This can create many files in .Ev TMPDIR or .Pa /tmp , so use with care. .It Cm p Print debugging information about makefile parsing. .It Cm s Print debugging information about suffix-transformation rules. .It Cm t Print debugging information about target list maintenance. .It Cm V Force the .Fl V option to print raw values of variables, overriding the default behavior set via .Va .MAKE.EXPAND_VARIABLES . .It Cm v Print debugging information about variable assignment and expansion. .It Cm x Run shell commands with .Fl x so the actual commands are printed as they are executed. .El .It Fl e Let environment variables override global variables within makefiles. .It Fl f Ar makefile Specify a makefile to read instead of the default .Pa makefile or .Pa Makefile . If .Ar makefile is .Ql \&- , standard input is read. Multiple makefiles may be specified, and are read in the order specified. .It Fl I Ar directory Specify a directory in which to search for makefiles and included makefiles. The system makefile directory (or directories, see the .Fl m option) is automatically included as part of this list. .It Fl i Ignore non-zero exit of shell commands in the makefile. Equivalent to specifying .Ql \&- before each command line in the makefile. .It Fl J Ar private This option should .Em not be specified by the user. .Pp When the .Fl j option is in use in a recursive build, this option is passed by a make to child makes to allow all the make processes in the build to cooperate to avoid overloading the system. .It Fl j Ar max_jobs Specify the maximum number of jobs that .Nm may have running at any one time. +If +.Ar max_jobs +is a floating point number, or ends with +.Ql C , +then the value is multiplied by the number of CPUs reported online by +.Xr sysconf 3 . The value of .Ar max_jobs is saved in .Va .MAKE.JOBS . Turns compatibility mode off, unless the .Fl B option is also specified. When compatibility mode is off, all commands associated with a target are executed in a single shell invocation as opposed to the traditional one shell invocation per line. This can break traditional scripts which change directories on each command invocation and then expect to start with a fresh environment on the next line. It is more efficient to correct the scripts rather than turn backwards compatibility on. .Pp A job token pool with .Ar max_jobs tokens is used to control the total number of jobs running. Each instance of .Nm will wait for a token from the pool before running a new job. .It Fl k Continue processing after errors are encountered, but only on those targets that do not depend on the target whose creation caused the error. .It Fl m Ar directory Specify a directory in which to search for .Pa sys.mk and makefiles included via the .Li \&< Ns Ar file Ns Li \&> Ns -style include statement. The .Fl m option can be used multiple times to form a search path. This path overrides the default system include path .Pa /usr/share/mk . Furthermore, the system include path is appended to the search path used for .Li \*q Ns Ar file Ns Li \*q Ns -style include statements (see the .Fl I option). The system include path can be referenced via the read-only variable .Va .SYSPATH . .Pp If a directory name in the .Fl m argument (or the .Ev MAKESYSPATH environment variable) starts with the string .Ql \&.../ , .Nm searches for the specified file or directory named in the remaining part of the argument string. The search starts with the current directory and then works upward towards the root of the file system. If the search is successful, the resulting directory replaces the .Ql \&.../ specification in the .Fl m argument. This feature allows .Nm to easily search in the current source tree for customized .Pa sys.mk files (e.g., by using .Ql \&.../mk/sys.mk as an argument). .It Fl n Display the commands that would have been executed, but do not actually execute them unless the target depends on the .Va .MAKE special source (see below) or the command is prefixed with .Sq Cm + . .It Fl N Display the commands that would have been executed, but do not actually execute any of them; useful for debugging top-level makefiles without descending into subdirectories. .It Fl q Do not execute any commands, instead exit 0 if the specified targets are up to date, and 1 otherwise. .It Fl r Do not use the built-in rules specified in the system makefile. .It Fl S Stop processing if an error is encountered. This is the default behavior and the opposite of .Fl k . .It Fl s Do not echo any commands as they are executed. Equivalent to specifying .Sq Ic @ before each command line in the makefile. .It Fl T Ar tracefile When used with the .Fl j flag, append a trace record to .Ar tracefile for each job started and completed. .It Fl t Rather than re-building a target as specified in the makefile, create it or update its modification time to make it appear up-to-date. .It Fl V Ar variable Print the value of .Ar variable . Do not build any targets. Multiple instances of this option may be specified; the variables are printed one per line, with a blank line for each null or undefined variable. The value printed is extracted from the global scope after all makefiles have been read. .Pp By default, the raw variable contents (which may include additional unexpanded variable references) are shown. If .Ar variable contains a .Ql \&$ , it is not interpreted as a variable name but rather as an expression. Its value is expanded before printing. The value is also expanded before printing if .Va .MAKE.EXPAND_VARIABLES is set to true and the .Fl dV option has not been used to override it. .Pp Note that loop-local and target-local variables, as well as values taken temporarily by global variables during makefile processing, are not accessible via this option. The .Fl dv debug mode can be used to see these at the cost of generating substantial extraneous output. .It Fl v Ar variable Like .Fl V , but all printed variables are always expanded to their complete value. The last occurrence of .Fl V or .Fl v decides whether all variables are expanded or not. .It Fl W Treat any warnings during makefile parsing as errors. .It Fl w Print entering and leaving directory messages, pre and post processing. .It Fl X Don't export variables passed on the command line to the environment individually. Variables passed on the command line are still exported via the .Ev MAKEFLAGS environment variable. This option may be useful on systems which have a small limit on the size of command arguments. .It Ar variable\| Ns Cm \&= Ns Ar value Set the value of the variable .Ar variable to .Ar value . Normally, all values passed on the command line are also exported to sub-makes in the environment. The .Fl X flag disables this behavior. Variable assignments should follow options for POSIX compatibility but no ordering is enforced. .El .Pp There are several different types of lines in a makefile: dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, other directives, and comments. .Pp Lines may be continued from one line to the next by ending them with a backslash .Pq Ql \e . The trailing newline character and initial whitespace on the following line are compressed into a single space. .Sh FILE DEPENDENCY SPECIFICATIONS Dependency lines consist of one or more targets, an operator, and zero or more sources. This creates a relationship where the targets .Dq depend on the sources and are customarily created from them. A target is considered out of date if it does not exist, or if its modification time is less than that of any of its sources. An out-of-date target is re-created, but not until all sources have been examined and themselves re-created as needed. Three operators may be used: .Bl -tag -width flag .It Ic \&: Many dependency lines may name this target but only one may have attached shell commands. All sources named in all dependency lines are considered together, and if needed the attached shell commands are run to create or re-create the target. If .Nm is interrupted, the target is removed. .It Ic \&! The same, but the target is always re-created whether or not it is out of date. .It Ic \&:: Any dependency line may have attached shell commands, but each one is handled independently: its sources are considered and the attached shell commands are run if the target is out of date with respect to (only) those sources. Thus, different groups of the attached shell commands may be run depending on the circumstances. Furthermore, unlike .Ic \&: , for dependency lines with no sources, the attached shell commands are always run. Also unlike .Ic \&: , the target is not removed if .Nm is interrupted. .El .Pp All dependency lines mentioning a particular target must use the same operator. .Pp Targets and sources may contain the shell wildcard values .Ql \&? , .Ql * , .Ql [] , and .Ql {} . The values .Ql \&? , .Ql * , and .Ql [] may only be used as part of the final component of the target or source, and only match existing files. The value .Ql {} need not necessarily be used to describe existing files. Expansion is in directory order, not alphabetically as done in the shell. .Sh SHELL COMMANDS Each target may have associated with it one or more lines of shell commands, normally used to create the target. Each of the lines in this script .Em must be preceded by a tab. (For historical reasons, spaces are not accepted.) While targets can occur in many dependency lines if desired, by default only one of these rules may be followed by a creation script. If the .Sq Ic \&:: operator is used, however, all rules may include scripts, and the respective scripts are executed in the order found. .Pp Each line is treated as a separate shell command, unless the end of line is escaped with a backslash .Ql \e , in which case that line and the next are combined. If the first characters of the command are any combination of .Sq Ic @ , .Sq Ic + , or .Sq Ic \- , the command is treated specially. .Bl -tag -offset indent -width indent .It Ic @ causes the command not to be echoed before it is executed. .It Ic + causes the command to be executed even when .Fl n is given. This is similar to the effect of the .Va .MAKE special source, except that the effect can be limited to a single line of a script. .It Ic \- in compatibility mode causes any non-zero exit status of the command line to be ignored. .El .Pp When .Nm is run in jobs mode with .Fl j Ar max_jobs , the entire script for the target is fed to a single instance of the shell. In compatibility (non-jobs) mode, each command is run in a separate process. If the command contains any shell meta characters .Pq Ql #=|^(){};&<>*?[]:$`\e\en , it is passed to the shell; otherwise .Nm attempts direct execution. If a line starts with .Sq Ic \- and the shell has ErrCtl enabled, failure of the command line is ignored as in compatibility mode. Otherwise .Sq Ic \- affects the entire job; the script stops at the first command line that fails, but the target is not deemed to have failed. .Pp Makefiles should be written so that the mode of .Nm operation does not change their behavior. For example, any command which uses .Dq cd or .Dq chdir without the intention of changing the directory for subsequent commands should be put in parentheses so it executes in a subshell. To force the use of a single shell, escape the line breaks so as to make the whole script one command. For example: .Bd -literal -offset indent avoid-chdir-side-effects: @echo "Building $@ in $$(pwd)" @(cd ${.CURDIR} && ${MAKE} $@) @echo "Back in $$(pwd)" ensure-one-shell-regardless-of-mode: @echo "Building $@ in $$(pwd)"; \e (cd ${.CURDIR} && ${MAKE} $@); \e echo "Back in $$(pwd)" .Ed .Pp Since .Nm changes the current working directory to .Sq Va .OBJDIR before executing any targets, each child process starts with that as its current working directory. .Sh VARIABLE ASSIGNMENTS Variables in make behave much like macros in the C preprocessor. .Pp Variable assignments have the form .Sq Ar NAME Ar op Ar value , where: .Bl -tag -offset Ds -width Ds .It Ar NAME is a single-word variable name, consisting, by tradition, of all upper-case letters, .It Ar op is one of the variable assignment operators described below, and .It Ar value is interpreted according to the variable assignment operator. .El .Pp Whitespace around .Ar NAME , .Ar op and .Ar value is discarded. .Ss Variable assignment operators The five operators that assign values to variables are: .Bl -tag -width Ds .It Ic \&= Assign the value to the variable. Any previous value is overwritten. .It Ic \&+= Append the value to the current value of the variable, separating them by a single space. .It Ic \&?= Assign the value to the variable if it is not already defined. .It Ic \&:= Expand the value, then assign it to the variable. .Pp .Em NOTE : References to undefined variables are .Em not expanded. This can cause problems when variable modifiers are used. .\" See var-op-expand.mk, the section with LATER and INDIRECT. .It Ic \&!= Expand the value and pass it to the shell for execution, then assign the output from the child's standard output to the variable. Any newlines in the result are replaced with spaces. .El .Ss Expansion of variables In most contexts where variables are expanded, .Ql \&$$ expands to a single dollar sign. In other contexts (most variable modifiers, string literals in conditions), .Ql \&\e$ expands to a single dollar sign. .Pp References to variables have the form .Cm \&${ Ns Ar name Ns Oo Ns Cm \&: Ns Ar modifiers Oc Ns Cm \&} or .Cm \&$( Ns Ar name Ns Oo Ns Cm \&: Ns Ar modifiers Oc Ns Cm \&) . If the variable name consists of only a single character and the expression contains no modifiers, the surrounding curly braces or parentheses are not required. This shorter form is not recommended. .Pp If the variable name contains a dollar, the name itself is expanded first. This allows almost arbitrary variable names, however names containing dollar, braces, parentheses or whitespace are really best avoided. .Pp If the result of expanding a nested variable expression contains a dollar sign .Pq Ql \&$ , the result is subject to further expansion. .Pp Variable substitution occurs at four distinct times, depending on where the variable is being used. .Bl -enum .It Variables in dependency lines are expanded as the line is read. .It Variables in conditionals are expanded individually, but only as far as necessary to determine the result of the conditional. .It Variables in shell commands are expanded when the shell command is executed. .It .Ic .for loop index variables are expanded on each loop iteration. Note that other variables are not expanded when composing the body of a loop, so the following example code: .Bd -literal -offset indent \&.for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} \&.endfor all: @echo ${a} @echo ${b} .Ed .Pp prints: .Bd -literal -offset indent 1 2 3 3 3 3 .Ed .Pp After the loop is executed: .Bl -tag -offset indent -width indent .It Va a contains .Ql ${:U1} ${:U2} ${:U3} , which expands to .Ql 1 2 3 . .It Va j contains .Ql ${:U3} , which expands to .Ql 3 . .It Va b contains .Ql ${j} ${j} ${j} , which expands to .Ql ${:U3} ${:U3} ${:U3} and further to .Ql 3 3 3 . .El .El .Ss Variable classes The four different classes of variables (in order of increasing precedence) are: .Bl -tag -width Ds .It Environment variables Variables defined as part of .Nm Ns 's environment. .It Global variables Variables defined in the makefile or in included makefiles. .It Command line variables Variables defined as part of the command line. .It Local variables Variables that are defined specific to a certain target. .El .Pp Local variables can be set on a dependency line, unless .Va .MAKE.TARGET_LOCAL_VARIABLES is set to .Ql false . The rest of the line (which already has had global variables expanded) is the variable value. For example: .Bd -literal -offset indent COMPILER_WRAPPERS= ccache distcc icecc ${OBJS}: .MAKE.META.CMP_FILTER=${COMPILER_WRAPPERS:S,^,N,} .Ed .Pp Only the targets .Ql ${OBJS} are impacted by that filter (in .Dq meta mode) and simply enabling/disabling any of the compiler wrappers does not render all of those targets out-of-date. .Pp .Em NOTE : target-local variable assignments behave differently in that; .Bl -tag -width Ds -offset indent .It Ic \&+= Only appends to a previous local assignment for the same target and variable. .It Ic \&:= Is redundant with respect to global variables, which have already been expanded. .El .Pp The seven built-in local variables are: .Bl -tag -width ".Va .ARCHIVE" -offset indent .It Va .ALLSRC The list of all sources for this target; also known as .Sq Va \&> . .It Va .ARCHIVE The name of the archive file; also known as .Sq Va \&! . .It Va .IMPSRC In suffix-transformation rules, the name/path of the source from which the target is to be transformed (the .Dq implied source); also known as .Sq Va \&< . It is not defined in explicit rules. .It Va .MEMBER The name of the archive member; also known as .Sq Va % . .It Va .OODATE The list of sources for this target that were deemed out-of-date; also known as .Sq Va \&? . .It Va .PREFIX The name of the target with suffix (if declared in .Ic .SUFFIXES ) removed; also known as .Sq Va * . .It Va .TARGET The name of the target; also known as .Sq Va @ . For compatibility with other makes this is an alias for .Va .ARCHIVE in archive member rules. .El .Pp The shorter forms .Po .Sq Va \&> , .Sq Va \&! , .Sq Va \&< , .Sq Va \&% , .Sq Va \&? , .Sq Va \&* , and .Sq Va \&@ .Pc are permitted for backward compatibility with historical makefiles and legacy POSIX make and are not recommended. .Pp Variants of these variables with the punctuation followed immediately by .Ql D or .Ql F , e.g.\& .Ql $(@D) , are legacy forms equivalent to using the .Ql :H and .Ql :T modifiers. These forms are accepted for compatibility with .At V makefiles and POSIX but are not recommended. .Pp Four of the local variables may be used in sources on dependency lines because they expand to the proper value for each target on the line. These variables are .Sq Va .TARGET , .Sq Va .PREFIX , .Sq Va .ARCHIVE , and .Sq Va .MEMBER . .Ss Additional built-in variables In addition, .Nm sets or knows about the following variables: .Bl -tag .\" NB: This list is sorted case-insensitive, ignoring punctuation. .\" NB: To find all built-in variables in make's source code, .\" NB: search for Var_*, Global_*, SetVarObjdir, GetBooleanExpr, .\" NB: and the implementation of Var_SetWithFlags. .\" NB: Last synced on 2023-01-01. .It Va .ALLTARGETS The list of all targets encountered in the makefiles. If evaluated during makefile parsing, lists only those targets encountered thus far. .It Va .CURDIR A path to the directory where .Nm was executed. Refer to the description of .Sq Va PWD for more details. .It Va .ERROR_CMD Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_CWD Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_META_FILE Is used in error handling in .Dq meta mode, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_TARGET Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .INCLUDEDFROMDIR The directory of the file this makefile was included from. .It Va .INCLUDEDFROMFILE The filename of the file this makefile was included from. .\" .INCLUDES is intentionally undocumented, as it is obsolete. .\" .LIBS is intentionally undocumented, as it is obsolete. .It Va MACHINE The machine hardware name, see .Xr uname 1 . .It Va MACHINE_ARCH The machine processor architecture name, see .Xr uname 1 . .It Va MAKE The name that .Nm was executed with .Pq Va argv[0] . .It Va .MAKE The same as .Va MAKE , for compatibility. The preferred variable to use is the environment variable .Ev MAKE because it is more compatible with other make variants and cannot be confused with the special target with the same name. .\" '.MAKE.cmd_filtered' is intentionally undocumented, .\" as it is an internal implementation detail. .It Va .MAKE.DEPENDFILE Names the makefile (default .Sq Pa .depend ) from which generated dependencies are read. .It Va .MAKE.DIE_QUIETLY If set to .Ql true , do not print error information at the end. .It Va .MAKE.EXPAND_VARIABLES A boolean that controls the default behavior of the .Fl V option. If true, variable values printed with .Fl V are fully expanded; if false, the raw variable contents (which may include additional unexpanded variable references) are shown. .It Va .MAKE.EXPORTED The list of variables exported by .Nm . .It Va MAKEFILE The top-level makefile that is currently read, as given in the command line. .It Va .MAKEFLAGS The environment variable .Sq Ev MAKEFLAGS may contain anything that may be specified on .Nm Ns 's command line. Anything specified on .Nm Ns 's command line is appended to the .Va .MAKEFLAGS variable, which is then added to the environment for all programs that .Nm executes. .It Va .MAKE.GID The numeric group ID of the user running .Nm . It is read-only. .It Va .MAKE.JOB.PREFIX If .Nm is run with .Fl j , the output for each target is prefixed with a token .Dl --- Ar target Li --- the first part of which can be controlled via .Va .MAKE.JOB.PREFIX . If .Va .MAKE.JOB.PREFIX is empty, no token is printed. For example, setting .Va .MAKE.JOB.PREFIX to .Ql ${.newline}---${.MAKE:T}[${.MAKE.PID}] would produce tokens like .Dl ---make[1234] Ar target Li --- making it easier to track the degree of parallelism being achieved. .It Va .MAKE.JOBS The argument to the .Fl j option. +.It Va .MAKE.JOBS.C +A read-only boolean that indicates whether the +.Fl j +option supports use of +.Ql C . .It Va .MAKE.LEVEL The recursion depth of .Nm . The top-level instance of .Nm has level 0, and each child make has its parent level plus 1. This allows tests like: .Li .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the top-level instance of .Nm . .It Va .MAKE.LEVEL.ENV The name of the environment variable that stores the level of nested calls to .Nm . .It Va .MAKE.MAKEFILE_PREFERENCE The ordered list of makefile names (default .Sq Pa makefile , .Sq Pa Makefile ) that .Nm looks for. .It Va .MAKE.MAKEFILES The list of makefiles read by .Nm , which is useful for tracking dependencies. Each makefile is recorded only once, regardless of the number of times read. .It Va .MAKE.META.BAILIWICK In .Dq meta mode, provides a list of prefixes which match the directories controlled by .Nm . If a file that was generated outside of .Va .OBJDIR but within said bailiwick is missing, the current target is considered out-of-date. .It Va .MAKE.META.CMP_FILTER In .Dq meta mode, it can (very rarely!) be useful to filter command lines before comparison. This variable can be set to a set of modifiers that are applied to each line of the old and new command that differ, if the filtered commands still differ, the target is considered out-of-date. .It Va .MAKE.META.CREATED In .Dq meta mode, this variable contains a list of all the meta files updated. If not empty, it can be used to trigger processing of .Va .MAKE.META.FILES . .It Va .MAKE.META.FILES In .Dq meta mode, this variable contains a list of all the meta files used (updated or not). This list can be used to process the meta files to extract dependency information. .It Va .MAKE.META.IGNORE_FILTER Provides a list of variable modifiers to apply to each pathname. Ignore if the expansion is an empty string. .It Va .MAKE.META.IGNORE_PATHS Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: .Sq Pa /dev /etc /proc /tmp /var/run /var/tmp .It Va .MAKE.META.IGNORE_PATTERNS Provides a list of patterns to match against pathnames. Ignore any that match. .It Va .MAKE.META.PREFIX Defines the message printed for each meta file updated in .Dq meta verbose mode. The default value is: .Dl Building ${.TARGET:H:tA}/${.TARGET:T} .It Va .MAKE.MODE Processed after reading all makefiles. Affects the mode that .Nm runs in. It can contain these keywords: .Bl -tag -width indent .It Cm compat Like .Fl B , puts .Nm into .Dq compat mode. .It Cm meta Puts .Nm into .Dq meta mode, where meta files are created for each target to capture the command run, the output generated, and if .Xr filemon 4 is available, the system calls which are of interest to .Nm . The captured output can be useful when diagnosing errors. .It Cm curdirOk= Ns Ar bf By default, .Nm does not create .Pa .meta files in .Sq Va .CURDIR . This can be overridden by setting .Ar bf to a value which represents true. .It Cm missing-meta= Ns Ar bf If .Ar bf is true, a missing .Pa .meta file makes the target out-of-date. .It Cm missing-filemon= Ns Ar bf If .Ar bf is true, missing filemon data makes the target out-of-date. .It Cm nofilemon Do not use .Xr filemon 4 . .It Cm env For debugging, it can be useful to include the environment in the .Pa .meta file. .It Cm verbose If in .Dq meta mode, print a clue about the target being built. This is useful if the build is otherwise running silently. The message printed is the expanded value of .Va .MAKE.META.PREFIX . .It Cm ignore-cmd Some makefiles have commands which are simply not stable. This keyword causes them to be ignored for determining whether a target is out of date in .Dq meta mode. See also .Ic .NOMETA_CMP . .It Cm silent= Ns Ar bf If .Ar bf is true, when a .meta file is created, mark the target .Ic .SILENT . .It Cm randomize-targets In both compat and parallel mode, do not make the targets in the usual order, but instead randomize their order. This mode can be used to detect undeclared dependencies between files. .El .It Va MAKEOBJDIR Used to create files in a separate directory, see .Va .OBJDIR . .It Va MAKE_OBJDIR_CHECK_WRITABLE Used to force a separate directory for the created files, even if that directory is not writable, see .Va .OBJDIR . .It Va MAKEOBJDIRPREFIX Used to create files in a separate directory, see .Va .OBJDIR . .It Va .MAKE.OS The name of the operating system, see .Xr uname 1 . It is read-only. .It Va .MAKEOVERRIDES This variable is used to record the names of variables assigned to on the command line, so that they may be exported as part of .Sq Ev MAKEFLAGS . This behavior can be disabled by assigning an empty value to .Sq Va .MAKEOVERRIDES within a makefile. Extra variables can be exported from a makefile by appending their names to .Sq Va .MAKEOVERRIDES . .Sq Ev MAKEFLAGS is re-exported whenever .Sq Va .MAKEOVERRIDES is modified. .It Va .MAKE.PATH_FILEMON If .Nm was built with .Xr filemon 4 support, this is set to the path of the device node. This allows makefiles to test for this support. .It Va .MAKE.PID The process ID of .Nm . It is read-only. .It Va .MAKE.PPID The parent process ID of .Nm . It is read-only. .It Va MAKE_PRINT_VAR_ON_ERROR When .Nm stops due to an error, it sets .Sq Va .ERROR_TARGET to the name of the target that failed, .Sq Va .ERROR_CMD to the commands of the failed target, and in .Dq meta mode, it also sets .Sq Va .ERROR_CWD to the .Xr getcwd 3 , and .Sq Va .ERROR_META_FILE to the path of the meta file (if any) describing the failed target. It then prints its name and the value of .Sq Va .CURDIR as well as the value of any variables named in .Sq Va MAKE_PRINT_VAR_ON_ERROR . .It Va .MAKE.SAVE_DOLLARS If true, .Ql $$ are preserved when doing .Ql := assignments. The default is false, for backwards compatibility. Set to true for compatability with other makes. If set to false, .Ql $$ becomes .Ql $ per normal evaluation rules. .It Va .MAKE.TARGET_LOCAL_VARIABLES If set to .Ql false , apparent variable assignments in dependency lines are treated as normal sources. .It Va .MAKE.UID The numeric ID of the user running .Nm . It is read-only. .\" 'MAKE_VERSION' is intentionally undocumented .\" since it is only defined in the bmake distribution, .\" but not in NetBSD's native make. .\" '.meta.%d.lcwd' is intentionally undocumented .\" since it is an internal implementation detail. .\" '.meta.%d.ldir' is intentionally undocumented .\" since it is an internal implementation detail. .\" 'MFLAGS' is intentionally undocumented .\" since it is obsolete. .It Va .newline This variable is simply assigned a newline character as its value. It is read-only. This allows expansions using the .Cm \&:@ modifier to put a newline between iterations of the loop rather than a space. For example, in case of an error, .Nm prints the variable names and their values using: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Va .OBJDIR A path to the directory where the targets are built. Its value is determined by trying to .Xr chdir 2 to the following directories in order and using the first match: .Bl -enum .It .Cm ${MAKEOBJDIRPREFIX} Ns Cm ${.CURDIR} .Pp (Only if .Sq Ev MAKEOBJDIRPREFIX is set in the environment or on the command line.) .It .Cm ${MAKEOBJDIR} .Pp (Only if .Sq Ev MAKEOBJDIR is set in the environment or on the command line.) .It .Cm ${.CURDIR} Ns Pa /obj. Ns Cm ${MACHINE} .It .Cm ${.CURDIR} Ns Pa /obj .It .Pa /usr/obj/ Ns Cm ${.CURDIR} .It .Cm ${.CURDIR} .El .Pp Variable expansion is performed on the value before it is used, so expressions such as .Cm ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with .Sq Ev MAKEOBJDIR . .Pp .Sq Va .OBJDIR may be modified in the makefile via the special target .Sq Ic .OBJDIR . In all cases, .Nm changes to the specified directory if it exists, and sets .Sq Va .OBJDIR and .Sq Va PWD to that directory before executing any targets. .Pp Except in the case of an explicit .Sq Ic .OBJDIR target, .Nm checks that the specified directory is writable and ignores it if not. This check can be skipped by setting the environment variable .Sq Ev MAKE_OBJDIR_CHECK_WRITABLE to .Dq no . .It Va .PARSEDIR The directory name of the current makefile being parsed. .It Va .PARSEFILE The basename of the current makefile being parsed. This variable and .Sq Va .PARSEDIR are both set only while the makefiles are being parsed. To retain their current values, assign them to a variable using assignment with expansion .Sq Cm \&:= . .It Va .PATH The space-separated list of directories that .Nm searches for files. To update this search list, use the special target .Sq Ic .PATH rather than modifying the variable directly. .It Va %POSIX Is set in POSIX mode, see the special .Ql Va .POSIX target. .\" XXX: There is no make variable named 'PWD', .\" XXX: make only reads and writes the environment variable 'PWD'. .It Va PWD Alternate path to the current directory. .Nm normally sets .Sq Va .CURDIR to the canonical path given by .Xr getcwd 3 . However, if the environment variable .Sq Ev PWD is set and gives a path to the current directory, .Nm sets .Sq Va .CURDIR to the value of .Sq Ev PWD instead. This behavior is disabled if .Sq Ev MAKEOBJDIRPREFIX is set or .Sq Ev MAKEOBJDIR contains a variable transform. .Sq Va PWD is set to the value of .Sq Va .OBJDIR for all programs which .Nm executes. .It Va .SHELL The pathname of the shell used to run target scripts. It is read-only. .It Va .SUFFIXES The list of known suffixes. It is read-only. .It Va .SYSPATH The space-separated list of directories that .Nm searches for makefiles, referred to as the system include path. To update this search list, use the special target .Sq Ic .SYSPATH rather than modifying the variable which is read-only. .It Va .TARGETS The list of targets explicitly specified on the command line, if any. .It Va VPATH The colon-separated .Pq Dq \&: list of directories that .Nm searches for files. This variable is supported for compatibility with old make programs only, use .Sq Va .PATH instead. .El .Ss Variable modifiers The general format of a variable expansion is: .Pp .Sm off .D1 Ic \&${ Ar variable\| Oo Ic \&: Ar modifier\| Oo Ic \&: No ... Oc Oc Ic \&} .Sm on .Pp Each modifier begins with a colon. To escape a colon, precede it with a backslash .Ql \e . .Pp A list of indirect modifiers can be specified via a variable, as follows: .Pp .Bd -literal -offset indent .Ar modifier_variable\^ Li \&= Ar modifier Ns Oo Ic \&: Ns No ... Oc .Sm off .Ic \&${ Ar variable Ic \&:${ Ar modifier_variable Ic \&} Oo Ic \&: No ... Oc Ic \&} .Sm on .Ed .Pp In this case, the first modifier in the .Ar modifier_variable does not start with a colon, since that colon already occurs in the referencing variable. If any of the modifiers in the .Ar modifier_variable contains a dollar sign .Pq Ql $ , these must be doubled to avoid early expansion. .Pp Some modifiers interpret the expression value as a single string, others treat the expression value as a whitespace-separated list of words. When splitting a string into words, whitespace can be escaped using double quotes, single quotes and backslashes, like in the shell. The quotes and backslashes are retained in the words. .Pp The supported modifiers are: .Bl -tag -width EEE .It Cm \&:E Replaces each word with its suffix. .It Cm \&:H Replaces each word with its dirname. .It Cm \&:M\| Ns Ar pattern Selects only those words that match .Ar pattern . The standard shell wildcard characters .Pf ( Ql * , .Ql \&? , and .Ql \&[] ) may be used. The wildcard characters may be escaped with a backslash .Pq Ql \e . As a consequence of the way values are split into words, matched, and then joined, the construct .Ql ${VAR:M*} removes all leading and trailing whitespace and normalizes the inter-word spacing to a single space. .It Cm \&:N\| Ns Ar pattern This is the opposite of .Sq Cm \&:M , selecting all words which do .Em not match .Ar pattern . .It Cm \&:O Orders the words lexicographically. .It Cm \&:On Orders the words numerically. A number followed by one of .Ql k , .Ql M or .Ql G is multiplied by the appropriate factor, which is 1024 for .Ql k , 1048576 for .Ql M , or 1073741824 for .Ql G . Both upper- and lower-case letters are accepted. .It Cm \&:Or Orders the words in reverse lexicographical order. .It Cm \&:Orn Orders the words in reverse numerical order. .It Cm \&:Ox Shuffles the words. The results are different each time you are referring to the modified variable; use the assignment with expansion .Sq Cm \&:= to prevent such behavior. For example, .Bd -literal -offset indent LIST= uno due tre quattro RANDOM_LIST= ${LIST:Ox} STATIC_RANDOM_LIST:= ${LIST:Ox} all: @echo "${RANDOM_LIST}" @echo "${RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" .Ed may produce output similar to: .Bd -literal -offset indent quattro due tre uno tre due quattro uno due uno quattro tre due uno quattro tre .Ed .It Cm \&:Q Quotes every shell meta-character in the value, so that it can be passed safely to the shell. .It Cm \&:q Quotes every shell meta-character in the value, and also doubles .Sq $ characters so that it can be passed safely through recursive invocations of .Nm . This is equivalent to .Sq Cm \&:S/\e\&$/&&/g:Q . .It Cm \&:R Replaces each word with everything but its suffix. .It Cm \&:range Ns Oo Cm = Ns Ar count Oc The value is an integer sequence representing the words of the original value, or the supplied .Ar count . .It Cm \&:gmtime Ns Oo Cm = Ns Ar timestamp Oc The value is interpreted as a format string for .Xr strftime 3 , using .Xr gmtime 3 , producing the formatted timestamp. +Note: the +.Ql %s +format should only be used with +.Sq Cm \&:localtime . If a .Ar timestamp value is not provided or is 0, the current time is used. .It Cm \&:hash Computes a 32-bit hash of the value and encodes it as 8 hex digits. .It Cm \&:localtime Ns Oo Cm = Ns Ar timestamp Oc The value is interpreted as a format string for .Xr strftime 3 , using .Xr localtime 3 , producing the formatted timestamp. If a .Ar timestamp value is not provided or is 0, the current time is used. .It Cm \&:mtime Ns Oo Cm = Ns Ar timestamp Oc Call .Xr stat 2 with each word as pathname; use .Ql st_mtime as the new value. If .Xr stat 2 fails; use .Ar timestamp or current time. If .Ar timestamp is set to .Ql error , then .Xr stat 2 failure will cause an error. .It Cm \&:tA Attempts to convert the value to an absolute path using .Xr realpath 3 . If that fails, the value is unchanged. .It Cm \&:tl Converts the value to lower-case letters. .It Cm \&:ts Ns Ar c When joining the words after a modifier that treats the value as words, the words are normally separated by a space. This modifier changes the separator to the character .Ar c . If .Ar c is omitted, no separator is used. The common escapes (including octal numeric codes) work as expected. .It Cm \&:tu Converts the value to upper-case letters. .It Cm \&:tW Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). See also .Sq Cm \&:[*] . .It Cm \&:tw Causes the value to be treated as a list of words. See also .Sq Cm \&:[@] . .Sm off .It Cm \&:S\| No \&/ Ar old_string\| No \&/ Ar new_string\| No \&/ Op Cm 1gW .Sm on Modifies the first occurrence of .Ar old_string in each word of the value, replacing it with .Ar new_string . If a .Ql g is appended to the last delimiter of the pattern, all occurrences in each word are replaced. If a .Ql 1 is appended to the last delimiter of the pattern, only the first occurrence is affected. If a .Ql W is appended to the last delimiter of the pattern, the value is treated as a single word. If .Ar old_string begins with a caret .Pq Ql ^ , .Ar old_string is anchored at the beginning of each word. If .Ar old_string ends with a dollar sign .Pq Ql \&$ , it is anchored at the end of each word. Inside .Ar new_string , an ampersand .Pq Ql & is replaced by .Ar old_string (without the anchoring .Ql ^ or .Ql \&$ ) . Any character may be used as the delimiter for the parts of the modifier string. The anchoring, ampersand and delimiter characters can be escaped with a backslash .Pq Ql \e . .Pp Both .Ar old_string and .Ar new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. .Sm off .It Cm \&:C\| No \&/ Ar pattern\| No \&/ Ar replacement\| No \&/ Op Cm 1gW .Sm on The .Cm \&:C modifier works like the .Cm \&:S modifier except that the old and new strings, instead of being simple strings, are an extended regular expression .Ar pattern (see .Xr regex 3 ) and an .Xr ed 1 Ns \-style .Ar replacement . Normally, the first occurrence of the pattern .Ar pattern in each word of the value is substituted with .Ar replacement . The .Ql 1 modifier causes the substitution to apply to at most one word; the .Ql g modifier causes the substitution to apply to as many instances of the search pattern .Ar pattern as occur in the word or words it is found in; the .Ql W modifier causes the value to be treated as a single word (possibly containing embedded whitespace). .Pp As for the .Cm \&:S modifier, the .Ar pattern and .Ar replacement are subjected to variable expansion before being parsed as regular expressions. .It Cm \&:T Replaces each word with its last path component (basename). .It Cm \&:u Removes adjacent duplicate words (like .Xr uniq 1 ) . .Sm off .It Cm \&:\&?\| Ar true_string\| Cm \&: Ar false_string .Sm on If the variable name (not its value), when parsed as a .Cm .if conditional expression, evaluates to true, return as its value the .Ar true_string , otherwise return the .Ar false_string . Since the variable name is used as the expression, \&:\&? must be the first modifier after the variable name .No itself Ns \^\(em\^ Ns which, of course, usually contains variable expansions. A common error is trying to use expressions like .Dl ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS). To determine if any words match .Dq 42 , you need to use something like: .Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} . .It Cm :\| Ns Ar old_string\| Ns Cm = Ns Ar new_string This is the .At V style substitution. It can only be the last modifier specified, as a .Ql \&: in either .Ar old_string or .Ar new_string is treated as a regular character, not as the end of the modifier. .Pp If .Ar old_string does not contain the pattern matching character .Ql % , and the word ends with .Ar old_string or equals it, that suffix is replaced with .Ar new_string . .Pp Otherwise, the first .Ql % in .Ar old_string matches a possibly empty substring of arbitrary characters, and if the whole pattern is found in the word, the matching part is replaced with .Ar new_string , and the first occurrence of .Ql % in .Ar new_string (if any) is replaced with the substring matched by the .Ql % . .Pp Both .Ar old_string and .Ar new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. .Sm off .It Cm \&:@ Ar varname\| Cm @ Ar string\| Cm @ .Sm on This is the loop expansion mechanism from the OSF Development Environment (ODE) make. Unlike .Cm \&.for loops, expansion occurs at the time of reference. For each word in the value, assign the word to the variable named .Ar varname and evaluate .Ar string . The ODE convention is that .Ar varname should start and end with a period, for example: .Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} .Pp However, a single-letter variable is often more readable: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Cm \&:_ Ns Oo Cm = Ns Ar var Oc Saves the current variable value in .Ql $_ or the named .Ar var for later reference. Example usage: .Bd -literal -offset indent M_cmpv.units = 1 1000 1000000 M_cmpv = S,., ,g:_:range:@i@+ $${_:[-$$i]} \&\\ \\* $${M_cmpv.units:[$$i]}@:S,^,expr 0 ,1:sh .Dv .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}} .Ed Here .Ql $_ is used to save the result of the .Ql :S modifier which is later referenced using the index values from .Ql :range . .It Cm \&:U\| Ns Ar newval If the variable is undefined, .Ar newval is the value. If the variable is defined, the existing value is returned. This is another ODE make feature. It is handy for setting per-target CFLAGS for instance: .Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}} If a value is only required if the variable is undefined, use: .Dl ${VAR:D:Unewval} .It Cm \&:D\| Ns Ar newval If the variable is defined, .Ar newval is the value. .It Cm \&:L The name of the variable is the value. .It Cm \&:P The path of the node which has the same name as the variable is the value. If no such node exists or its path is null, the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the right-hand side of a dependency. .Sm off .It Cm \&:\&! Ar cmd\| Cm \&! .Sm on The output of running .Ar cmd is the value. .It Cm \&:sh The value is run as a command, and the output becomes the new value. .It Cm \&::= Ns Ar str The variable is assigned the value .Ar str after substitution. This modifier and its variations are useful in obscure situations such as wanting to set a variable at a point where a target's shell commands are being parsed. These assignment modifiers always expand to nothing. .Pp The .Sq Cm \&:: helps avoid false matches with the .At V style .Ql \&:= modifier and since substitution always occurs, the .Ql \&::= form is vaguely appropriate. .It Cm \&::?= Ns Ar str As for .Cm \&::= but only if the variable does not already have a value. .It Cm \&::+= Ns Ar str Append .Ar str to the variable. .It Cm \&::!= Ns Ar cmd Assign the output of .Ar cmd to the variable. .It Cm \&:\&[ Ns Ar range Ns Cm \&] Selects one or more words from the value, or performs other operations related to the way in which the value is split into words. .Pp An empty value, or a value that consists entirely of white-space, is treated as a single word. For the purposes of the .Sq Cm \&:[] modifier, the words are indexed both forwards using positive integers (where index 1 represents the first word), and backwards using negative integers (where index \-1 represents the last word). .Pp The .Ar range is subjected to variable expansion, and the expanded result is then interpreted as follows: .Bl -tag -width index .\" :[n] .It Ar index Selects a single word from the value. .\" :[start..end] .It Ar start Ns Cm \&.. Ns Ar end Selects all words from .Ar start to .Ar end , inclusive. For example, .Sq Cm \&:[2..-1] selects all words from the second word to the last word. If .Ar start is greater than .Ar end , the words are output in reverse order. For example, .Sq Cm \&:[-1..1] selects all the words from last to first. If the list is already ordered, this effectively reverses the list, but it is more efficient to use .Sq Cm \&:Or instead of .Sq Cm \&:O:[-1..1] . .\" :[*] .It Cm \&* Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). Analogous to the effect of .Li \&$* in Bourne shell. .\" :[0] .It 0 Means the same as .Sq Cm \&:[*] . .\" :[*] .It Cm \&@ Causes subsequent modifiers to treat the value as a sequence of words delimited by whitespace. Analogous to the effect of .Li \&$@ in Bourne shell. .\" :[#] .It Cm \&# Returns the number of words in the value. .El \" :[range] .El .Sh DIRECTIVES .Nm offers directives for including makefiles, conditionals and for loops. All these directives are identified by a line beginning with a single dot .Pq Ql \&. character, followed by the keyword of the directive, such as .Cm include or .Cm if . .Ss File inclusion Files are included with either .Cm \&.include \&< Ns Ar file Ns Cm \&> or .Cm \&.include \&\*q Ns Ar file Ns Cm \&\*q . Variables between the angle brackets or double quotes are expanded to form the file name. If angle brackets are used, the included makefile is expected to be in the system makefile directory. If double quotes are used, the including makefile's directory and any directories specified using the .Fl I option are searched before the system makefile directory. .Pp For compatibility with other make variants, .Sq Cm include Ar file No ... (without leading dot) is also accepted. .Pp If the include statement is written as .Cm .-include or as .Cm .sinclude , errors locating and/or opening include files are ignored. .Pp If the include statement is written as .Cm .dinclude , not only are errors locating and/or opening include files ignored, but stale dependencies within the included file are ignored just like in .Va .MAKE.DEPENDFILE . .Ss Exporting variables The directives for exporting and unexporting variables are: .Bl -tag -width Ds .It Ic .export Ar variable No ... Export the specified global variable. If no variable list is provided, all globals are exported except for internal variables (those that start with .Ql \&. ) . This is not affected by the .Fl X flag, so should be used with caution. For compatibility with other make programs, .Cm export Ar variable\| Ns Cm \&= Ns Ar value (without leading dot) is also accepted. .Pp Appending a variable name to .Va .MAKE.EXPORTED is equivalent to exporting a variable. .It Ic .export-env Ar variable No ... The same as .Ql .export , except that the variable is not appended to .Va .MAKE.EXPORTED . This allows exporting a value to the environment which is different from that used by .Nm internally. .It Ic .export-literal Ar variable No ... The same as .Ql .export-env , except that variables in the value are not expanded. .It Ic .unexport Ar variable No ... The opposite of .Ql .export . The specified global .Ar variable is removed from .Va .MAKE.EXPORTED . If no variable list is provided, all globals are unexported, and .Va .MAKE.EXPORTED deleted. .It Ic .unexport-env Unexport all globals previously exported and clear the environment inherited from the parent. This operation causes a memory leak of the original environment, so should be used sparingly. Testing for .Va .MAKE.LEVEL being 0 would make sense. Also note that any variables which originated in the parent environment should be explicitly preserved if desired. For example: .Bd -literal -offset indent .Li .if ${.MAKE.LEVEL} == 0 PATH := ${PATH} .Li .unexport-env .Li .export PATH .Li .endif .Pp .Ed Would result in an environment containing only .Sq Ev PATH , which is the minimal useful environment. .\" TODO: Check the below sentence, environment variables don't start with '.'. Actually .Sq Va .MAKE.LEVEL is also pushed into the new environment. .El .Ss Messages The directives for printing messages to the output are: .Bl -tag -width Ds .It Ic .info Ar message The message is printed along with the name of the makefile and line number. .It Ic .warning Ar message The message prefixed by .Sq Li warning: is printed along with the name of the makefile and line number. .It Ic .error Ar message The message is printed along with the name of the makefile and line number, .Nm exits immediately. .El .Ss Conditionals The directives for conditionals are: .ds maybenot Oo Ic \&! Oc Ns .Bl -tag .It Ic .if \*[maybenot] Ar expression Op Ar operator expression No ... Test the value of an expression. .It Ic .ifdef \*[maybenot] Ar variable Op Ar operator variable No ... Test whether a variable is defined. .It Ic .ifndef \*[maybenot] Ar variable Op Ar operator variable No ... Test whether a variable is not defined. .It Ic .ifmake \*[maybenot] Ar target Op Ar operator target No ... Test the target being requested. .It Ic .ifnmake \*[maybenot] Ar target Op Ar operator target No ... Test the target being requested. .It Ic .else Reverse the sense of the last conditional. .It Ic .elif \*[maybenot] Ar expression Op Ar operator expression No ... A combination of .Sq Ic .else followed by .Sq Ic .if . .It Ic .elifdef \*[maybenot] Ar variable Op Ar operator variable No ... A combination of .Sq Ic .else followed by .Sq Ic .ifdef . .It Ic .elifndef \*[maybenot] Ar variable Op Ar operator variable No ... A combination of .Sq Ic .else followed by .Sq Ic .ifndef . .It Ic .elifmake \*[maybenot] Ar target Op Ar operator target No ... A combination of .Sq Ic .else followed by .Sq Ic .ifmake . .It Ic .elifnmake \*[maybenot] Ar target Op Ar operator target No ... A combination of .Sq Ic .else followed by .Sq Ic .ifnmake . .It Ic .endif End the body of the conditional. .El .Pp The .Ar operator may be any one of the following: .Bl -tag .It Ic \&|\&| Logical OR. .It Ic \&&& Logical AND; of higher precedence than .Sq Ic \&|\&| . .El .Pp .Nm only evaluates a conditional as far as is necessary to determine its value. Parentheses can be used to override the operator precedence. The boolean operator .Sq Ic \&! -may be used to logically negate an entire conditional. +may be used to logically negate an expression, typically a function call. It is of higher precedence than .Sq Ic \&&& . .Pp The value of .Ar expression may be any of the following function call expressions: .Bl -tag .Sm off .It Ic defined Li \&( Ar varname Li \&) .Sm on Evaluates to true if the variable .Ar varname has been defined. .Sm off .It Ic make Li \&( Ar target Li \&) .Sm on Evaluates to true if the target was specified as part of .Nm Ns 's command line or was declared the default target (either implicitly or explicitly, see .Va .MAIN ) before the line containing the conditional. .Sm off .It Ic empty Li \&( Ar varname Oo Li : Ar modifiers Oc Li \&) .Sm on Evaluates to true if the expansion of the variable, after applying the modifiers, results in an empty string. .Sm off .It Ic exists Li \&( Ar pathname Li \&) .Sm on Evaluates to true if the given pathname exists. If relative, the pathname is searched for on the system search path (see .Va .PATH ) . .Sm off .It Ic target Li \&( Ar target Li \&) .Sm on Evaluates to true if the target has been defined. .Sm off .It Ic commands Li \&( Ar target Li \&) .Sm on Evaluates to true if the target has been defined and has commands associated with it. .El .Pp .Ar Expression may also be an arithmetic or string comparison. Variable expansion is performed on both sides of the comparison. If both sides are numeric and neither is enclosed in quotes, the comparison is done numerically, otherwise lexicographically. -A string is interpreted as hexadecimal integer if it is preceded by +A string is interpreted as a hexadecimal integer if it is preceded by .Li 0x , -otherwise it is a decimal floating-point number; +otherwise it is interpreted as a decimal floating-point number; octal numbers are not supported. .Pp All comparisons may use the operators .Sq Ic \&== and .Sq Ic \&!= . Numeric comparisons may also use the operators .Sq Ic \&< , .Sq Ic \&<= , .Sq Ic \&> and .Sq Ic \&>= . .Pp If the comparison has neither a comparison operator nor a right side, the expression evaluates to true if it is nonempty and its numeric value (if any) is not zero. .Pp When .Nm is evaluating one of these conditional expressions, and it encounters -a (whitespace separated) word it doesn't recognize, either the +a (whitespace-separated) word it doesn't recognize, either the .Dq make or .Dq defined function is applied to it, depending on the form of the conditional. If the form is .Sq Ic .ifdef , .Sq Ic .ifndef or .Sq Ic .if , the .Dq defined function is applied. Similarly, if the form is .Sq Ic .ifmake or .Sq Ic .ifnmake , the .Dq make function is applied. .Pp If the conditional evaluates to true, parsing of the makefile continues as before. -If it evaluates to false, the following lines are skipped. -In both cases, this continues until the corresponding +If it evaluates to false, the following lines until the corresponding +.Sq Ic .elif +variant, .Sq Ic .else or .Sq Ic .endif -is found. +are skipped. .Ss For loops For loops are typically used to apply a set of rules to a list of files. The syntax of a for loop is: .Pp .Bl -tag -compact -width Ds .It Ic \&.for Ar variable Oo Ar variable No ... Oc Ic in Ar expression .It Aq Ar make-lines .It Ic \&.endfor .El .Pp The .Ar expression is expanded and then split into words. On each iteration of the loop, one word is taken and assigned to each .Ar variable , in order, and these .Ar variables are substituted into the .Ar make-lines inside the body of the for loop. The number of words must come out even; that is, if there are three iteration variables, the number of words provided must be a multiple of three. .Pp If .Sq Ic .break is encountered within a .Cm \&.for loop, it causes early termination of the loop, otherwise a parse error. .\" TODO: Describe limitations with defined/empty. .Ss Other directives .Bl -tag -width Ds .It Ic .undef Ar variable No ... Un-define the specified global variables. Only global variables can be un-defined. .El .Sh COMMENTS Comments begin with a hash .Pq Ql \&# character, anywhere but in a shell command line, and continue to the end of an unescaped new line. .Sh SPECIAL SOURCES (ATTRIBUTES) .Bl -tag -width .IGNOREx .It Ic .EXEC Target is never out of date, but always execute commands anyway. .It Ic .IGNORE Ignore any errors from the commands associated with this target, exactly as if they all were preceded by a dash .Pq Ql \- . .\" .It Ic .INVISIBLE .\" XXX .\" .It Ic .JOIN .\" XXX .It Ic .MADE Mark all sources of this target as being up to date. .It Ic .MAKE Execute the commands associated with this target even if the .Fl n or .Fl t options were specified. Normally used to mark recursive .Nm Ns s . .It Ic .META Create a meta file for the target, even if it is flagged as .Ic .PHONY , .Ic .MAKE , or .Ic .SPECIAL . Usage in conjunction with .Ic .MAKE is the most likely case. In .Dq meta mode, the target is out-of-date if the meta file is missing. .It Ic .NOMETA Do not create a meta file for the target. Meta files are also not created for .Ic .PHONY , .Ic .MAKE , or .Ic .SPECIAL targets. .It Ic .NOMETA_CMP Ignore differences in commands when deciding if target is out of date. This is useful if the command contains a value which always changes. If the number of commands change, though, the target is still considered out of date. The same effect applies to any command line that uses the variable .Va .OODATE , which can be used for that purpose even when not otherwise needed or desired: .Bd -literal -offset indent skip-compare-for-some: @echo this is compared @echo this is not ${.OODATE:M.NOMETA_CMP} @echo this is also compared .Ed The .Cm \&:M pattern suppresses any expansion of the unwanted variable. .It Ic .NOPATH Do not search for the target in the directories specified by .Va .PATH . .It Ic .NOTMAIN Normally .Nm selects the first target it encounters as the default target to be built if no target was specified. This source prevents this target from being selected. .It Ic .OPTIONAL If a target is marked with this attribute and .Nm can't figure out how to create it, it ignores this fact and assumes the file isn't needed or already exists. .It Ic .PHONY The target does not correspond to an actual file; it is always considered to be out of date, and is not created with the .Fl t option. Suffix-transformation rules are not applied to .Ic .PHONY targets. .It Ic .PRECIOUS When .Nm is interrupted, it normally removes any partially made targets. This source prevents the target from being removed. .It Ic .RECURSIVE Synonym for .Ic .MAKE . .It Ic .SILENT Do not echo any of the commands associated with this target, exactly as if they all were preceded by an at sign .Pq Ql @ . .It Ic .USE Turn the target into .Nm Ns 's version of a macro. When the target is used as a source for another target, the other target acquires the commands, sources, and attributes (except for .Ic .USE ) of the source. If the target already has commands, the .Ic .USE target's commands are appended to them. .It Ic .USEBEFORE Like .Ic .USE , but instead of appending, prepend the .Ic .USEBEFORE target commands to the target. .It Ic .WAIT If .Ic .WAIT appears in a dependency line, the sources that precede it are made before the sources that succeed it in the line. Since the dependents of files are not made until the file itself could be made, this also stops the dependents being built unless they are needed for another branch of the dependency tree. So given: .Bd -literal x: a .WAIT b echo x a: echo a b: b1 echo b b1: echo b1 .Ed the output is always .Ql a , .Ql b1 , .Ql b , .Ql x . .Pp The ordering imposed by .Ic .WAIT is only relevant for parallel makes. .El .Sh SPECIAL TARGETS Special targets may not be included with other targets, i.e. they must be the only target specified. .Bl -tag -width .BEGINx .It Ic .BEGIN Any command lines attached to this target are executed before anything else is done. .It Ic .DEFAULT This is sort of a .Ic .USE rule for any target (that was used only as a source) that .Nm can't figure out any other way to create. Only the shell script is used. The .Va .IMPSRC variable of a target that inherits .Ic .DEFAULT Ns 's commands is set to the target's own name. .It Ic .DELETE_ON_ERROR If this target is present in the makefile, it globally causes make to delete targets whose commands fail. (By default, only targets whose commands are interrupted during execution are deleted. This is the historical behavior.) This setting can be used to help prevent half-finished or malformed targets from being left around and corrupting future rebuilds. .It Ic .END Any command lines attached to this target are executed after everything else is done successfully. .It Ic .ERROR Any command lines attached to this target are executed when another target fails. The .Va .ERROR_TARGET variable is set to the target that failed. See also .Va MAKE_PRINT_VAR_ON_ERROR . .It Ic .IGNORE Mark each of the sources with the .Ic .IGNORE attribute. If no sources are specified, this is the equivalent of specifying the .Fl i option. .It Ic .INTERRUPT If .Nm is interrupted, the commands for this target are executed. .It Ic .MAIN If no target is specified when .Nm is invoked, this target is built. .It Ic .MAKEFLAGS This target provides a way to specify flags for .Nm at the time when the makefiles are read. The flags are as if typed to the shell, though the .Fl f option has no effect. .\" XXX: NOT YET!!!! .\" .It Ic .NOTPARALLEL .\" The named targets are executed in non parallel mode. .\" If no targets are .\" specified, all targets are executed in non parallel mode. .It Ic .NOPATH Apply the .Ic .NOPATH attribute to any specified sources. .It Ic .NOTPARALLEL Disable parallel mode. .It Ic .NO_PARALLEL Synonym for .Ic .NOTPARALLEL , for compatibility with other pmake variants. .It Ic .NOREADONLY clear the read-only attribute from the global variables specified as sources. .It Ic .OBJDIR The source is a new value for .Sq Va .OBJDIR . If it exists, .Nm changes the current working directory to it and updates the value of .Sq Va .OBJDIR . .It Ic .ORDER In parallel mode, the named targets are made in sequence. This ordering does not add targets to the list of targets to be made. .Pp Since the dependents of a target do not get built until the target itself could be built, unless .Ql a is built by another part of the dependency graph, the following is a dependency loop: .Bd -literal \&.ORDER: b a b: a .Ed .Pp .\" XXX: NOT YET!!!! .\" .It Ic .PARALLEL .\" The named targets are executed in parallel mode. .\" If no targets are .\" specified, all targets are executed in parallel mode. .It Ic .PATH The sources are directories which are to be searched for files not found in the current directory. If no sources are specified, any previously specified directories are removed from the search path. If the source is the special .Ic .DOTLAST target, the current working directory is searched last. .It Ic .PATH. Ns Ar suffix Like .Ic .PATH but applies only to files with a particular suffix. The suffix must have been previously declared with .Ic .SUFFIXES . .It Ic .PHONY Apply the .Ic .PHONY attribute to any specified sources. .It Ic .POSIX If this is the first non-comment line in the main makefile, the variable .Va %POSIX is set to the value .Ql 1003.2 and the makefile .Ql is included if it exists, to provide POSIX-compatible default rules. If .Nm is run with the .Fl r flag, only .Ql posix.mk contributes to the default rules. .It Ic .PRECIOUS Apply the .Ic .PRECIOUS attribute to any specified sources. If no sources are specified, the .Ic .PRECIOUS attribute is applied to every target in the file. .It Ic .READONLY set the read-only attribute on the global variables specified as sources. .It Ic .SHELL Sets the shell that .Nm uses to execute commands in jobs mode. The sources are a set of .Ar field\| Ns Cm \&= Ns Ar value pairs. .Bl -tag -width ".Li hasErrCtls" .It Li name This is the minimal specification, used to select one of the built-in shell specs; .Li sh , .Li ksh , and .Li csh . .It Li path Specifies the absolute path to the shell. .It Li hasErrCtl Indicates whether the shell supports exit on error. .It Li check The command to turn on error checking. .It Li ignore The command to disable error checking. .It Li echo The command to turn on echoing of commands executed. .It Li quiet The command to turn off echoing of commands executed. .It Li filter The output to filter after issuing the .Li quiet command. It is typically identical to .Li quiet . .It Li errFlag The flag to pass the shell to enable error checking. .It Li echoFlag The flag to pass the shell to enable command echoing. .It Li newline The string literal to pass the shell that results in a single newline character when used outside of any quoting characters. .El Example: .Bd -literal \&.SHELL: name=ksh path=/bin/ksh hasErrCtl=true \e check="set \-e" ignore="set +e" \e echo="set \-v" quiet="set +v" filter="set +v" \e echoFlag=v errFlag=e newline="'\en'" .Ed .It Ic .SILENT Apply the .Ic .SILENT attribute to any specified sources. If no sources are specified, the .Ic .SILENT attribute is applied to every command in the file. .It Ic .STALE This target gets run when a dependency file contains stale entries, having .Va .ALLSRC set to the name of that dependency file. .It Ic .SUFFIXES Each source specifies a suffix to .Nm . If no sources are specified, any previously specified suffixes are deleted. It allows the creation of suffix-transformation rules. .Pp Example: .Bd -literal \&.SUFFIXES: .c .o \&.c.o: cc \-o ${.TARGET} \-c ${.IMPSRC} .Ed .It Ic .SYSPATH The sources are directories which are to be added to the system include path which .Nm searches for makefiles. If no sources are specified, any previously specified directories are removed from the system include path. .El .Sh ENVIRONMENT .Nm uses the following environment variables, if they exist: .Ev MACHINE , .Ev MACHINE_ARCH , .Ev MAKE , .Ev MAKEFLAGS , .Ev MAKEOBJDIR , .Ev MAKEOBJDIRPREFIX , .Ev MAKESYSPATH , .Ev PWD , and .Ev TMPDIR . .Pp .Ev MAKEOBJDIRPREFIX and .Ev MAKEOBJDIR may only be set in the environment or on the command line to .Nm and not as makefile variables; see the description of .Sq Va .OBJDIR for more details. .Sh FILES .Bl -tag -width /usr/share/mk -compact .It .depend list of dependencies .It makefile first default makefile if no makefile is specified on the command line .It Makefile second default makefile if no makefile is specified on the command line .It sys.mk system makefile .It /usr/share/mk system makefile directory .El .Sh COMPATIBILITY The basic make syntax is compatible between different make variants; however the special variables, variable modifiers and conditionals are not. .Ss Older versions An incomplete list of changes in older versions of .Nm : .Pp The way that .for loop variables are substituted changed after NetBSD 5.0 so that they still appear to be variable expansions. In particular this stops them being treated as syntax, and removes some obscure problems using them in .if statements. .Pp The way that parallel makes are scheduled changed in NetBSD 4.0 so that .ORDER and .WAIT apply recursively to the dependent nodes. The algorithms used may change again in the future. .Ss Other make dialects Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not support most of the features of .Nm as described in this manual. Most notably: .Bl -bullet -offset indent .It The .Ic .WAIT and .Ic .ORDER declarations and most functionality pertaining to parallelization. (GNU make supports parallelization but lacks the features needed to control it effectively.) .It Directives, including for loops and conditionals and most of the forms of include files. (GNU make has its own incompatible and less powerful syntax for conditionals.) .\" The "less powerful" above means that GNU make does not have the .\" make(target), target(target) and commands(target) functions. .It All built-in variables that begin with a dot. .It Most of the special sources and targets that begin with a dot, with the notable exception of .Ic .PHONY , .Ic .PRECIOUS , and .Ic .SUFFIXES . .It Variable modifiers, except for the .Ql :old=new string substitution, which does not portably support globbing with .Ql % and historically only works on declared suffixes. .It The .Ic $> variable even in its short form; most makes support this functionality but its name varies. .El .Pp Some features are somewhat more portable, such as assignment with .Ic += , .Ic ?= , and .Ic != . The .Va .PATH functionality is based on an older feature .Ic VPATH found in GNU make and many versions of SVR4 make; however, historically its behavior is too ill-defined (and too buggy) to rely upon. .Pp The .Ic $@ and .Ic $< variables are more or less universally portable, as is the .Ic $(MAKE) variable. Basic use of suffix rules (for files only in the current directory, not trying to chain transformations together, etc.) is also reasonably portable. .Sh SEE ALSO .Xr mkdep 1 .Sh HISTORY .Nm is derived from NetBSD .Xr make 1 . It uses autoconf to facilitate portability to other platforms. .Pp A make command appeared in .At v7 . This make implementation is based on Adam de Boor's pmake program, which was written for Sprite at Berkeley. It was designed to be a parallel distributed make running jobs on different machines using a daemon called .Dq customs . .Pp Historically the target/dependency .Ic FRC has been used to FoRCe rebuilding (since the target/dependency does not exist ... unless someone creates an .Pa FRC file). .Sh BUGS The make syntax is difficult to parse. For instance, finding the end of a variable's use should involve scanning each of the modifiers, using the correct terminator for each field. In many places make just counts {} and () in order to find the end of a variable expansion. .Pp There is no way of escaping a space character in a filename. .Pp In jobs mode, when a target fails; make will put an error token into the job token pool. This will cause all other instances of make using that token pool to abort the build and exit with error code 6. Sometimes the attempt to suppress a cascade of unnecessary errors, can result in a seemingly unexplained .Ql *** Error code 6 diff --git a/contrib/bmake/bmake.cat1 b/contrib/bmake/bmake.cat1 index 6f69dfb9f3ad..bdd48dda11db 100644 --- a/contrib/bmake/bmake.cat1 +++ b/contrib/bmake/bmake.cat1 @@ -1,1756 +1,1762 @@ BMAKE(1) FreeBSD General Commands Manual BMAKE(1) NAME bmake -- maintain program dependencies SYNOPSIS bmake [-BeikNnqrSstWwX] [-C directory] [-D variable] [-d flags] [-f makefile] [-I directory] [-J private] [-j max_jobs] [-m directory] [-T file] [-V variable] [-v variable] [variable=value] [target ...] DESCRIPTION bmake is a program designed to simplify the maintenance of other pro- grams. Its input is a list of specifications as to the files upon which programs and other files depend. If no -f makefile option is given, bmake tries to open `makefile' then `Makefile' in order to find the spec- ifications. If the file `.depend' exists, it is read, see mkdep(1). This manual page is intended as a reference document only. For a more thorough description of bmake and makefiles, please refer to PMake - A Tutorial (from 1993). bmake prepends the contents of the MAKEFLAGS environment variable to the command line arguments before parsing them. The options are as follows: -B Try to be backwards compatible by executing a single shell per command and by making the sources of a dependency line in se- quence. -C directory Change to directory before reading the makefiles or doing any- thing else. If multiple -C options are specified, each is inter- preted relative to the previous one: -C / -C etc is equivalent to -C /etc. -D variable Define variable to be 1, in the global scope. -d [-]flags Turn on debugging, and specify which portions of bmake are to print debugging information. Unless the flags are preceded by `-', they are added to the MAKEFLAGS environment variable and are passed on to any child make processes. By default, debugging in- formation is printed to standard error, but this can be changed using the F debugging flag. The debugging output is always un- buffered; in addition, if debugging is enabled but debugging out- put is not directed to standard output, the standard output is line buffered. The available flags are: A Print all possible debugging information; equivalent to specifying all of the debugging flags. a Print debugging information about archive searching and caching. C Print debugging information about the current working di- rectory. c Print debugging information about conditional evaluation. d Print debugging information about directory searching and caching. e Print debugging information about failed commands and targets. F[+]filename Specify where debugging output is written. This must be the last flag, because it consumes the remainder of the argument. If the character immediately after the F flag is `+', the file is opened in append mode; otherwise the file is overwritten. If the file name is `stdout' or `stderr', debugging output is written to the standard output or standard error output respectively (and the `+' option has no effect). Otherwise, the output is written to the named file. If the file name ends with `.%d', the `%d' is replaced by the pid. f Print debugging information about loop evaluation. g1 Print the input graph before making anything. g2 Print the input graph after making everything, or before exiting on error. g3 Print the input graph before exiting on error. h Print debugging information about hash table operations. j Print debugging information about running multiple shells. L Turn on lint checks. This throws errors for variable as- signments that do not parse correctly, at the time of as- signment, so the file and line number are available. l Print commands in Makefiles regardless of whether or not they are prefixed by `@' or other "quiet" flags. Also known as "loud" behavior. M Print debugging information about "meta" mode decisions about targets. m Print debugging information about making targets, includ- ing modification dates. n Don't delete the temporary command scripts created when running commands. These temporary scripts are created in the directory referred to by the TMPDIR environment vari- able, or in /tmp if TMPDIR is unset or set to the empty string. The temporary scripts are created by mkstemp(3), and have names of the form makeXXXXXX. NOTE: This can create many files in TMPDIR or /tmp, so use with care. p Print debugging information about makefile parsing. s Print debugging information about suffix-transformation rules. t Print debugging information about target list mainte- nance. V Force the -V option to print raw values of variables, overriding the default behavior set via .MAKE.EXPAND_VARIABLES. v Print debugging information about variable assignment and expansion. x Run shell commands with -x so the actual commands are printed as they are executed. -e Let environment variables override global variables within make- files. -f makefile Specify a makefile to read instead of the default makefile or Makefile. If makefile is `-', standard input is read. Multiple makefiles may be specified, and are read in the order specified. -I directory Specify a directory in which to search for makefiles and included makefiles. The system makefile directory (or directories, see the -m option) is automatically included as part of this list. -i Ignore non-zero exit of shell commands in the makefile. Equiva- lent to specifying `-' before each command line in the makefile. -J private This option should not be specified by the user. When the -j option is in use in a recursive build, this option is passed by a make to child makes to allow all the make processes in the build to cooperate to avoid overloading the system. -j max_jobs Specify the maximum number of jobs that bmake may have running at - any one time. The value of max_jobs is saved in .MAKE.JOBS. - Turns compatibility mode off, unless the -B option is also speci- - fied. When compatibility mode is off, all commands associated - with a target are executed in a single shell invocation as op- - posed to the traditional one shell invocation per line.

It is more efficient to correct the + scripts rather than turn backwards compatibility on. A job token pool with max_jobs tokens is used to control the to- tal number of jobs running. Each instance of bmake will wait for a token from the pool before running a new job. -k Continue processing after errors are encountered, but only on those targets that do not depend on the target whose creation caused the error. -m directory Specify a directory in which to search for sys.mk and makefiles included via the <file>-style include statement. The -m option can be used multiple times to form a search path. This path overrides the default system include path /usr/share/mk. Fur- thermore, the system include path is appended to the search path used for "file"-style include statements (see the -I option). The system include path can be referenced via the read-only vari- able .SYSPATH. If a directory name in the -m argument (or the MAKESYSPATH envi- ronment variable) starts with the string `.../', bmake searches for the specified file or directory named in the remaining part of the argument string. The search starts with the current di- rectory and then works upward towards the root of the file sys- tem. If the search is successful, the resulting directory re- places the `.../' specification in the -m argument. This feature allows bmake to easily search in the current source tree for cus- tomized sys.mk files (e.g., by using `.../mk/sys.mk' as an argu- ment). -n Display the commands that would have been executed, but do not actually execute them unless the target depends on the .MAKE spe- cial source (see below) or the command is prefixed with `+'. -N Display the commands that would have been executed, but do not actually execute any of them; useful for debugging top-level makefiles without descending into subdirectories. -q Do not execute any commands, instead exit 0 if the specified tar- gets are up to date, and 1 otherwise. -r Do not use the built-in rules specified in the system makefile. -S Stop processing if an error is encountered. This is the default behavior and the opposite of -k. -s Do not echo any commands as they are executed. Equivalent to specifying `@' before each command line in the makefile. -T tracefile When used with the -j flag, append a trace record to tracefile for each job started and completed. -t Rather than re-building a target as specified in the makefile, create it or update its modification time to make it appear up- to-date. -V variable Print the value of variable. Do not build any targets. Multiple instances of this option may be specified; the variables are printed one per line, with a blank line for each null or unde- fined variable. The value printed is extracted from the global scope after all makefiles have been read. By default, the raw variable contents (which may include addi- tional unexpanded variable references) are shown. If variable contains a `$', it is not interpreted as a variable name but rather as an expression. Its value is expanded before printing. The value is also expanded before printing if .MAKE.EXPAND_VARIABLES is set to true and the -dV option has not been used to override it. Note that loop-local and target-local variables, as well as val- ues taken temporarily by global variables during makefile pro- cessing, are not accessible via this option. The -dv debug mode can be used to see these at the cost of generating substantial extraneous output. -v variable Like -V, but all printed variables are always expanded to their complete value. The last occurrence of -V or -v decides whether all variables are expanded or not. -W Treat any warnings during makefile parsing as errors. -w Print entering and leaving directory messages, pre and post pro- cessing. -X Don't export variables passed on the command line to the environ- ment individually. Variables passed on the command line are still exported via the MAKEFLAGS environment variable. This op- tion may be useful on systems which have a small limit on the size of command arguments. variable=value Set the value of the variable variable to value. Normally, all values passed on the command line are also exported to sub-makes in the environment. The -X flag disables this behavior. Vari- able assignments should follow options for POSIX compatibility but no ordering is enforced. There are several different types of lines in a makefile: dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, other directives, and comments. Lines may be continued from one line to the next by ending them with a backslash (`\'). The trailing newline character and initial whitespace on the following line are compressed into a single space. FILE DEPENDENCY SPECIFICATIONS Dependency lines consist of one or more targets, an operator, and zero or more sources. This creates a relationship where the targets "depend" on the sources and are customarily created from them. A target is consid- ered out of date if it does not exist, or if its modification time is less than that of any of its sources. An out-of-date target is re-cre- ated, but not until all sources have been examined and themselves re-cre- ated as needed. Three operators may be used: : Many dependency lines may name this target but only one may have attached shell commands. All sources named in all dependency lines are considered together, and if needed the attached shell commands are run to create or re-create the target. If bmake is inter- rupted, the target is removed. ! The same, but the target is always re-created whether or not it is out of date. :: Any dependency line may have attached shell commands, but each one is handled independently: its sources are considered and the at- tached shell commands are run if the target is out of date with re- spect to (only) those sources. Thus, different groups of the at- tached shell commands may be run depending on the circumstances. Furthermore, unlike :, for dependency lines with no sources, the attached shell commands are always run. Also unlike :, the target is not removed if bmake is interrupted. All dependency lines mentioning a particular target must use the same op- erator. Targets and sources may contain the shell wildcard values `?', `*', `[]', and `{}'. The values `?', `*', and `[]' may only be used as part of the final component of the target or source, and only match existing files. The value `{}' need not necessarily be used to describe existing files. Expansion is in directory order, not alphabetically as done in the shell. SHELL COMMANDS Each target may have associated with it one or more lines of shell com- mands, normally used to create the target. Each of the lines in this script must be preceded by a tab. (For historical reasons, spaces are not accepted.) While targets can occur in many dependency lines if de- sired, by default only one of these rules may be followed by a creation script. If the `::' operator is used, however, all rules may include scripts, and the respective scripts are executed in the order found. Each line is treated as a separate shell command, unless the end of line is escaped with a backslash `\', in which case that line and the next are combined. If the first characters of the command are any combination of `@', `+', or `-', the command is treated specially. @ causes the command not to be echoed before it is executed. + causes the command to be executed even when -n is given. This is similar to the effect of the .MAKE special source, except that the effect can be limited to a single line of a script. - in compatibility mode causes any non-zero exit status of the command line to be ignored. When bmake is run in jobs mode with -j max_jobs, the entire script for the target is fed to a single instance of the shell. In compatibility (non-jobs) mode, each command is run in a separate process. If the com- mand contains any shell meta characters (`#=|^(){};&<>*?[]:$`\\n'), it is passed to the shell; otherwise bmake attempts direct execution. If a line starts with `-' and the shell has ErrCtl enabled, failure of the command line is ignored as in compatibility mode. Otherwise `-' affects the entire job; the script stops at the first command line that fails, but the target is not deemed to have failed. Makefiles should be written so that the mode of bmake operation does not change their behavior. For example, any command which uses "cd" or "chdir" without the intention of changing the directory for subsequent commands should be put in parentheses so it executes in a subshell. To force the use of a single shell, escape the line breaks so as to make the whole script one command. For example: avoid-chdir-side-effects: @echo "Building $@ in $$(pwd)" @(cd ${.CURDIR} && ${MAKE} $@) @echo "Back in $$(pwd)" ensure-one-shell-regardless-of-mode: @echo "Building $@ in $$(pwd)"; \ (cd ${.CURDIR} && ${MAKE} $@); \ echo "Back in $$(pwd)" Since bmake changes the current working directory to `.OBJDIR' before ex- ecuting any targets, each child process starts with that as its current working directory. VARIABLE ASSIGNMENTS Variables in make behave much like macros in the C preprocessor. Variable assignments have the form `NAME op value', where: NAME is a single-word variable name, consisting, by tradition, of all upper-case letters, op is one of the variable assignment operators described be- low, and value is interpreted according to the variable assignment opera- tor. Whitespace around NAME, op and value is discarded. Variable assignment operators The five operators that assign values to variables are: = Assign the value to the variable. Any previous value is over- written. += Append the value to the current value of the variable, separating them by a single space. ?= Assign the value to the variable if it is not already defined. := Expand the value, then assign it to the variable. NOTE: References to undefined variables are not expanded. This can cause problems when variable modifiers are used. != Expand the value and pass it to the shell for execution, then as- sign the output from the child's standard output to the variable. Any newlines in the result are replaced with spaces. Expansion of variables In most contexts where variables are expanded, `$$' expands to a single dollar sign. In other contexts (most variable modifiers, string literals in conditions), `\$' expands to a single dollar sign. References to variables have the form ${name[:modifiers]} or $(name[:modifiers]). If the variable name consists of only a single character and the expression contains no modifiers, the surrounding curly braces or parentheses are not required. This shorter form is not recom- mended. If the variable name contains a dollar, the name itself is expanded first. This allows almost arbitrary variable names, however names con- taining dollar, braces, parentheses or whitespace are really best avoided. If the result of expanding a nested variable expression contains a dollar sign (`$'), the result is subject to further expansion. Variable substitution occurs at four distinct times, depending on where the variable is being used. 1. Variables in dependency lines are expanded as the line is read. 2. Variables in conditionals are expanded individually, but only as far as necessary to determine the result of the conditional. 3. Variables in shell commands are expanded when the shell command is executed. 4. .for loop index variables are expanded on each loop iteration. Note that other variables are not expanded when composing the body of a loop, so the following example code: .for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} .endfor all: @echo ${a} @echo ${b} prints: 1 2 3 3 3 3 After the loop is executed: a contains `${:U1} ${:U2} ${:U3}', which expands to `1 2 3'. j contains `${:U3}', which expands to `3'. b contains `${j} ${j} ${j}', which expands to `${:U3} ${:U3} ${:U3}' and further to `3 3 3'. Variable classes The four different classes of variables (in order of increasing prece- dence) are: Environment variables Variables defined as part of bmake's environment. Global variables Variables defined in the makefile or in included makefiles. Command line variables Variables defined as part of the command line. Local variables Variables that are defined specific to a certain target. Local variables can be set on a dependency line, unless .MAKE.TARGET_LOCAL_VARIABLES is set to `false'. The rest of the line (which already has had global variables expanded) is the variable value. For example: COMPILER_WRAPPERS= ccache distcc icecc ${OBJS}: .MAKE.META.CMP_FILTER=${COMPILER_WRAPPERS:S,^,N,} Only the targets `${OBJS}' are impacted by that filter (in "meta" mode) and simply enabling/disabling any of the compiler wrappers does not ren- der all of those targets out-of-date. NOTE: target-local variable assignments behave differently in that; += Only appends to a previous local assignment for the same target and variable. := Is redundant with respect to global variables, which have already been expanded. The seven built-in local variables are: .ALLSRC The list of all sources for this target; also known as `>'. .ARCHIVE The name of the archive file; also known as `!'. .IMPSRC In suffix-transformation rules, the name/path of the source from which the target is to be transformed (the "implied" source); also known as `<'. It is not defined in explicit rules. .MEMBER The name of the archive member; also known as `%'. .OODATE The list of sources for this target that were deemed out- of-date; also known as `?'. .PREFIX The name of the target with suffix (if declared in .SUFFIXES) removed; also known as `*'. .TARGET The name of the target; also known as `@'. For compati- bility with other makes this is an alias for .ARCHIVE in archive member rules. The shorter forms (`>', `!', `<', `%', `?', `*', and `@') are permitted for backward compatibility with historical makefiles and legacy POSIX make and are not recommended. Variants of these variables with the punctuation followed immediately by `D' or `F', e.g. `$(@D)', are legacy forms equivalent to using the `:H' and `:T' modifiers. These forms are accepted for compatibility with AT&T System V UNIX makefiles and POSIX but are not recommended. Four of the local variables may be used in sources on dependency lines because they expand to the proper value for each target on the line. These variables are `.TARGET', `.PREFIX', `.ARCHIVE', and `.MEMBER'. Additional built-in variables In addition, bmake sets or knows about the following variables: .ALLTARGETS The list of all targets encountered in the makefiles. If evalu- ated during makefile parsing, lists only those targets encoun- tered thus far. .CURDIR A path to the directory where bmake was executed. Refer to the description of `PWD' for more details. .ERROR_CMD Is used in error handling, see MAKE_PRINT_VAR_ON_ERROR. .ERROR_CWD Is used in error handling, see MAKE_PRINT_VAR_ON_ERROR. .ERROR_META_FILE Is used in error handling in "meta" mode, see MAKE_PRINT_VAR_ON_ERROR. .ERROR_TARGET Is used in error handling, see MAKE_PRINT_VAR_ON_ERROR. .INCLUDEDFROMDIR The directory of the file this makefile was included from. .INCLUDEDFROMFILE The filename of the file this makefile was included from. MACHINE The machine hardware name, see uname(1). MACHINE_ARCH The machine processor architecture name, see uname(1). MAKE The name that bmake was executed with (argv[0]). .MAKE The same as MAKE, for compatibility. The preferred variable to use is the environment variable MAKE because it is more compati- ble with other make variants and cannot be confused with the spe- cial target with the same name. .MAKE.DEPENDFILE Names the makefile (default `.depend') from which generated de- pendencies are read. .MAKE.DIE_QUIETLY If set to `true', do not print error information at the end. .MAKE.EXPAND_VARIABLES A boolean that controls the default behavior of the -V option. If true, variable values printed with -V are fully expanded; if false, the raw variable contents (which may include additional unexpanded variable references) are shown. .MAKE.EXPORTED The list of variables exported by bmake. MAKEFILE The top-level makefile that is currently read, as given in the command line. .MAKEFLAGS The environment variable `MAKEFLAGS' may contain anything that may be specified on bmake's command line. Anything specified on bmake's command line is appended to the .MAKEFLAGS variable, which is then added to the environment for all programs that bmake executes. .MAKE.GID The numeric group ID of the user running bmake. It is read-only. .MAKE.JOB.PREFIX If bmake is run with -j, the output for each target is prefixed with a token --- target --- the first part of which can be controlled via .MAKE.JOB.PREFIX. If .MAKE.JOB.PREFIX is empty, no token is printed. For example, setting .MAKE.JOB.PREFIX to `${.newline}---${.MAKE:T}[${.MAKE.PID}]' would produce tokens like ---make[1234] target --- making it easier to track the degree of parallelism being achieved. .MAKE.JOBS The argument to the -j option. + .MAKE.JOBS.C + A read-only boolean that indicates whether the -j option supports + use of `C'. + .MAKE.LEVEL The recursion depth of bmake. The top-level instance of bmake has level 0, and each child make has its parent level plus 1. This allows tests like: .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the top-level instance of bmake. .MAKE.LEVEL.ENV The name of the environment variable that stores the level of nested calls to bmake. .MAKE.MAKEFILE_PREFERENCE The ordered list of makefile names (default `makefile', `Makefile') that bmake looks for. .MAKE.MAKEFILES The list of makefiles read by bmake, which is useful for tracking dependencies. Each makefile is recorded only once, regardless of the number of times read. .MAKE.META.BAILIWICK In "meta" mode, provides a list of prefixes which match the di- rectories controlled by bmake. If a file that was generated out- side of .OBJDIR but within said bailiwick is missing, the current target is considered out-of-date. .MAKE.META.CMP_FILTER In "meta" mode, it can (very rarely!) be useful to filter command lines before comparison. This variable can be set to a set of modifiers that are applied to each line of the old and new com- mand that differ, if the filtered commands still differ, the tar- get is considered out-of-date. .MAKE.META.CREATED In "meta" mode, this variable contains a list of all the meta files updated. If not empty, it can be used to trigger process- ing of .MAKE.META.FILES. .MAKE.META.FILES In "meta" mode, this variable contains a list of all the meta files used (updated or not). This list can be used to process the meta files to extract dependency information. .MAKE.META.IGNORE_FILTER Provides a list of variable modifiers to apply to each pathname. Ignore if the expansion is an empty string. .MAKE.META.IGNORE_PATHS Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: `/dev /etc /proc /tmp /var/run /var/tmp' .MAKE.META.IGNORE_PATTERNS Provides a list of patterns to match against pathnames. Ignore any that match. .MAKE.META.PREFIX Defines the message printed for each meta file updated in "meta verbose" mode. The default value is: Building ${.TARGET:H:tA}/${.TARGET:T} .MAKE.MODE Processed after reading all makefiles. Affects the mode that bmake runs in. It can contain these keywords: compat Like -B, puts bmake into "compat" mode. meta Puts bmake into "meta" mode, where meta files are created for each target to capture the command run, the output generated, and if filemon(4) is available, the system calls which are of interest to bmake. The captured out- put can be useful when diagnosing errors. curdirOk=bf By default, bmake does not create .meta files in `.CURDIR'. This can be overridden by setting bf to a value which represents true. missing-meta=bf If bf is true, a missing .meta file makes the target out- of-date. missing-filemon=bf If bf is true, missing filemon data makes the target out- of-date. nofilemon Do not use filemon(4). env For debugging, it can be useful to include the environ- ment in the .meta file. verbose If in "meta" mode, print a clue about the target being built. This is useful if the build is otherwise running silently. The message printed is the expanded value of .MAKE.META.PREFIX. ignore-cmd Some makefiles have commands which are simply not stable. This keyword causes them to be ignored for determining whether a target is out of date in "meta" mode. See also .NOMETA_CMP. silent=bf If bf is true, when a .meta file is created, mark the target .SILENT. randomize-targets In both compat and parallel mode, do not make the targets in the usual order, but instead randomize their order. This mode can be used to detect undeclared dependencies between files. MAKEOBJDIR Used to create files in a separate directory, see .OBJDIR. MAKE_OBJDIR_CHECK_WRITABLE Used to force a separate directory for the created files, even if that directory is not writable, see .OBJDIR. MAKEOBJDIRPREFIX Used to create files in a separate directory, see .OBJDIR. .MAKE.OS The name of the operating system, see uname(1). It is read-only. .MAKEOVERRIDES This variable is used to record the names of variables assigned to on the command line, so that they may be exported as part of `MAKEFLAGS'. This behavior can be disabled by assigning an empty value to `.MAKEOVERRIDES' within a makefile. Extra variables can be exported from a makefile by appending their names to `.MAKEOVERRIDES'. `MAKEFLAGS' is re-exported whenever `.MAKEOVERRIDES' is modified. .MAKE.PATH_FILEMON If bmake was built with filemon(4) support, this is set to the path of the device node. This allows makefiles to test for this support. .MAKE.PID The process ID of bmake. It is read-only. .MAKE.PPID The parent process ID of bmake. It is read-only. MAKE_PRINT_VAR_ON_ERROR When bmake stops due to an error, it sets `.ERROR_TARGET' to the name of the target that failed, `.ERROR_CMD' to the commands of the failed target, and in "meta" mode, it also sets `.ERROR_CWD' to the getcwd(3), and `.ERROR_META_FILE' to the path of the meta file (if any) describing the failed target. It then prints its name and the value of `.CURDIR' as well as the value of any vari- ables named in `MAKE_PRINT_VAR_ON_ERROR'. .MAKE.SAVE_DOLLARS If true, `$$' are preserved when doing `:=' assignments. The de- fault is false, for backwards compatibility. Set to true for compatability with other makes. If set to false, `$$' becomes `$' per normal evaluation rules. .MAKE.TARGET_LOCAL_VARIABLES If set to `false', apparent variable assignments in dependency lines are treated as normal sources. .MAKE.UID The numeric ID of the user running bmake. It is read-only. .newline This variable is simply assigned a newline character as its value. It is read-only. This allows expansions using the :@ modifier to put a newline between iterations of the loop rather than a space. For example, in case of an error, bmake prints the variable names and their values using: ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .OBJDIR A path to the directory where the targets are built. Its value is determined by trying to chdir(2) to the following directories in order and using the first match: 1. ${MAKEOBJDIRPREFIX}${.CURDIR} (Only if `MAKEOBJDIRPREFIX' is set in the environment or on the command line.) 2. ${MAKEOBJDIR} (Only if `MAKEOBJDIR' is set in the environment or on the command line.) 3. ${.CURDIR}/obj.${MACHINE} 4. ${.CURDIR}/obj 5. /usr/obj/${.CURDIR} 6. ${.CURDIR} Variable expansion is performed on the value before it is used, so expressions such as ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with `MAKEOBJDIR'. `.OBJDIR' may be modified in the makefile via the special target `.OBJDIR'. In all cases, bmake changes to the specified direc- tory if it exists, and sets `.OBJDIR' and `PWD' to that directory before executing any targets. Except in the case of an explicit `.OBJDIR' target, bmake checks that the specified directory is writable and ignores it if not. This check can be skipped by setting the environment variable `MAKE_OBJDIR_CHECK_WRITABLE' to "no". .PARSEDIR The directory name of the current makefile being parsed. .PARSEFILE The basename of the current makefile being parsed. This variable and `.PARSEDIR' are both set only while the makefiles are being parsed. To retain their current values, assign them to a vari- able using assignment with expansion `:='. .PATH The space-separated list of directories that bmake searches for files. To update this search list, use the special target `.PATH' rather than modifying the variable directly. %POSIX Is set in POSIX mode, see the special `.POSIX' target. PWD Alternate path to the current directory. bmake normally sets `.CURDIR' to the canonical path given by getcwd(3). However, if the environment variable `PWD' is set and gives a path to the current directory, bmake sets `.CURDIR' to the value of `PWD' in- stead. This behavior is disabled if `MAKEOBJDIRPREFIX' is set or `MAKEOBJDIR' contains a variable transform. `PWD' is set to the value of `.OBJDIR' for all programs which bmake executes. .SHELL The pathname of the shell used to run target scripts. It is read-only. .SUFFIXES The list of known suffixes. It is read-only. .SYSPATH The space-separated list of directories that bmake searches for makefiles, referred to as the system include path. To update this search list, use the special target `.SYSPATH' rather than modifying the variable which is read-only. .TARGETS The list of targets explicitly specified on the command line, if any. VPATH The colon-separated (":") list of directories that bmake searches for files. This variable is supported for compatibility with old make programs only, use `.PATH' instead. Variable modifiers The general format of a variable expansion is: ${variable[:modifier[:...]]} Each modifier begins with a colon. To escape a colon, precede it with a backslash `\'. A list of indirect modifiers can be specified via a variable, as follows: modifier_variable = modifier[:...] ${variable:${modifier_variable}[:...]} In this case, the first modifier in the modifier_variable does not start with a colon, since that colon already occurs in the referencing vari- able. If any of the modifiers in the modifier_variable contains a dollar sign (`$'), these must be doubled to avoid early expansion. Some modifiers interpret the expression value as a single string, others treat the expression value as a whitespace-separated list of words. When splitting a string into words, whitespace can be escaped using double quotes, single quotes and backslashes, like in the shell. The quotes and backslashes are retained in the words. The supported modifiers are: :E Replaces each word with its suffix. :H Replaces each word with its dirname. :Mpattern Selects only those words that match pattern. The standard shell wildcard characters (`*', `?', and `[]') may be used. The wildcard characters may be escaped with a backslash (`\'). As a consequence of the way values are split into words, matched, and then joined, the construct `${VAR:M*}' removes all leading and trailing white- space and normalizes the inter-word spacing to a single space. :Npattern This is the opposite of `:M', selecting all words which do not match pattern. :O Orders the words lexicographically. :On Orders the words numerically. A number followed by one of `k', `M' or `G' is multiplied by the appropriate factor, which is 1024 for `k', 1048576 for `M', or 1073741824 for `G'. Both upper- and lower- case letters are accepted. :Or Orders the words in reverse lexicographical order. :Orn Orders the words in reverse numerical order. :Ox Shuffles the words. The results are different each time you are re- ferring to the modified variable; use the assignment with expansion `:=' to prevent such behavior. For example, LIST= uno due tre quattro RANDOM_LIST= ${LIST:Ox} STATIC_RANDOM_LIST:= ${LIST:Ox} all: @echo "${RANDOM_LIST}" @echo "${RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" may produce output similar to: quattro due tre uno tre due quattro uno due uno quattro tre due uno quattro tre :Q Quotes every shell meta-character in the value, so that it can be passed safely to the shell. :q Quotes every shell meta-character in the value, and also doubles `$' characters so that it can be passed safely through recursive invoca- tions of bmake. This is equivalent to `:S/\$/&&/g:Q'. :R Replaces each word with everything but its suffix. :range[=count] The value is an integer sequence representing the words of the orig- inal value, or the supplied count. :gmtime[=timestamp] The value is interpreted as a format string for strftime(3), using - gmtime(3), producing the formatted timestamp. If a timestamp value - is not provided or is 0, the current time is used. + gmtime(3), producing the formatted timestamp. Note: the `%s' format + should only be used with `:localtime'. If a timestamp value is not + provided or is 0, the current time is used. :hash Computes a 32-bit hash of the value and encodes it as 8 hex digits. :localtime[=timestamp] The value is interpreted as a format string for strftime(3), using localtime(3), producing the formatted timestamp. If a timestamp value is not provided or is 0, the current time is used. :mtime[=timestamp] Call stat(2) with each word as pathname; use `st_mtime' as the new value. If stat(2) fails; use timestamp or current time. If timestamp is set to `error', then stat(2) failure will cause an er- ror. :tA Attempts to convert the value to an absolute path using realpath(3). If that fails, the value is unchanged. :tl Converts the value to lower-case letters. :tsc When joining the words after a modifier that treats the value as words, the words are normally separated by a space. This modifier changes the separator to the character c. If c is omitted, no sepa- rator is used. The common escapes (including octal numeric codes) work as expected. :tu Converts the value to upper-case letters. :tW Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). See also `:[*]'. :tw Causes the value to be treated as a list of words. See also `:[@]'. :S/old_string/new_string/[1gW] Modifies the first occurrence of old_string in each word of the value, replacing it with new_string. If a `g' is appended to the last delimiter of the pattern, all occurrences in each word are re- placed. If a `1' is appended to the last delimiter of the pattern, only the first occurrence is affected. If a `W' is appended to the last delimiter of the pattern, the value is treated as a single word. If old_string begins with a caret (`^'), old_string is an- chored at the beginning of each word. If old_string ends with a dollar sign (`$'), it is anchored at the end of each word. Inside new_string, an ampersand (`&') is replaced by old_string (without the anchoring `^' or `$'). Any character may be used as the delim- iter for the parts of the modifier string. The anchoring, ampersand and delimiter characters can be escaped with a backslash (`\'). Both old_string and new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. :C/pattern/replacement/[1gW] The :C modifier works like the :S modifier except that the old and new strings, instead of being simple strings, are an extended regu- lar expression pattern (see regex(3)) and an ed(1)-style replacement. Normally, the first occurrence of the pattern pattern in each word of the value is substituted with replacement. The `1' modifier causes the substitution to apply to at most one word; the `g' modifier causes the substitution to apply to as many instances of the search pattern pattern as occur in the word or words it is found in; the `W' modifier causes the value to be treated as a sin- gle word (possibly containing embedded whitespace). As for the :S modifier, the pattern and replacement are subjected to variable expansion before being parsed as regular expressions. :T Replaces each word with its last path component (basename). :u Removes adjacent duplicate words (like uniq(1)). :?true_string:false_string If the variable name (not its value), when parsed as a .if condi- tional expression, evaluates to true, return as its value the true_string, otherwise return the false_string. Since the variable name is used as the expression, :? must be the first modifier after the variable name itself--which, of course, usually contains vari- able expansions. A common error is trying to use expressions like ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS). To determine if any words match "42", you need to use something like: ${"${NUMBERS:M42}" != "":?match:no}. :old_string=new_string This is the AT&T System V UNIX style substitution. It can only be the last modifier specified, as a `:' in either old_string or new_string is treated as a regular character, not as the end of the modifier. If old_string does not contain the pattern matching character `%', and the word ends with old_string or equals it, that suffix is re- placed with new_string. Otherwise, the first `%' in old_string matches a possibly empty sub- string of arbitrary characters, and if the whole pattern is found in the word, the matching part is replaced with new_string, and the first occurrence of `%' in new_string (if any) is replaced with the substring matched by the `%'. Both old_string and new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. :@varname@string@ This is the loop expansion mechanism from the OSF Development Envi- ronment (ODE) make. Unlike .for loops, expansion occurs at the time of reference. For each word in the value, assign the word to the variable named varname and evaluate string. The ODE convention is that varname should start and end with a period, for example: ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} However, a single-letter variable is often more readable: ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} :_[=var] Saves the current variable value in `$_' or the named var for later reference. Example usage: M_cmpv.units = 1 1000 1000000 M_cmpv = S,., ,g:_:range:@i@+ $${_:[-$$i]} \ \* $${M_cmpv.units:[$$i]}@:S,^,expr 0 ,1:sh .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}} Here `$_' is used to save the result of the `:S' modifier which is later referenced using the index values from `:range'. :Unewval If the variable is undefined, newval is the value. If the variable is defined, the existing value is returned. This is another ODE make feature. It is handy for setting per-target CFLAGS for in- stance: ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}} If a value is only required if the variable is undefined, use: ${VAR:D:Unewval} :Dnewval If the variable is defined, newval is the value. :L The name of the variable is the value. :P The path of the node which has the same name as the variable is the value. If no such node exists or its path is null, the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the right-hand side of a de- pendency. :!cmd! The output of running cmd is the value. :sh The value is run as a command, and the output becomes the new value. ::=str The variable is assigned the value str after substitution. This modifier and its variations are useful in obscure situations such as wanting to set a variable at a point where a target's shell commands are being parsed. These assignment modifiers always expand to noth- ing. The `::' helps avoid false matches with the AT&T System V UNIX style `:=' modifier and since substitution always occurs, the `::=' form is vaguely appropriate. ::?=str As for ::= but only if the variable does not already have a value. ::+=str Append str to the variable. ::!=cmd Assign the output of cmd to the variable. :[range] Selects one or more words from the value, or performs other opera- tions related to the way in which the value is split into words. An empty value, or a value that consists entirely of white-space, is treated as a single word. For the purposes of the `:[]' modifier, the words are indexed both forwards using positive integers (where index 1 represents the first word), and backwards using negative in- tegers (where index -1 represents the last word). The range is subjected to variable expansion, and the expanded re- sult is then interpreted as follows: index Selects a single word from the value. start..end Selects all words from start to end, inclusive. For example, `:[2..-1]' selects all words from the second word to the last word. If start is greater than end, the words are output in reverse order. For example, `:[-1..1]' selects all the words from last to first. If the list is already ordered, this ef- fectively reverses the list, but it is more efficient to use `:Or' instead of `:O:[-1..1]'. * Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). Analogous to the effect of $* in Bourne shell. 0 Means the same as `:[*]'. @ Causes subsequent modifiers to treat the value as a sequence of words delimited by whitespace. Analogous to the effect of $@ in Bourne shell. # Returns the number of words in the value. DIRECTIVES bmake offers directives for including makefiles, conditionals and for loops. All these directives are identified by a line beginning with a single dot (`.') character, followed by the keyword of the directive, such as include or if. File inclusion Files are included with either .include <file> or .include "file". Vari- ables between the angle brackets or double quotes are expanded to form the file name. If angle brackets are used, the included makefile is ex- pected to be in the system makefile directory. If double quotes are used, the including makefile's directory and any directories specified using the -I option are searched before the system makefile directory. For compatibility with other make variants, `include file ...' (without leading dot) is also accepted. If the include statement is written as .-include or as .sinclude, errors locating and/or opening include files are ignored. If the include statement is written as .dinclude, not only are errors lo- cating and/or opening include files ignored, but stale dependencies within the included file are ignored just like in .MAKE.DEPENDFILE. Exporting variables The directives for exporting and unexporting variables are: .export variable ... Export the specified global variable. If no variable list is provided, all globals are exported except for internal variables (those that start with `.'). This is not affected by the -X flag, so should be used with caution. For compatibility with other make programs, export variable=value (without leading dot) is also accepted. Appending a variable name to .MAKE.EXPORTED is equivalent to ex- porting a variable. .export-env variable ... The same as `.export', except that the variable is not appended to .MAKE.EXPORTED. This allows exporting a value to the environ- ment which is different from that used by bmake internally. .export-literal variable ... The same as `.export-env', except that variables in the value are not expanded. .unexport variable ... The opposite of `.export'. The specified global variable is re- moved from .MAKE.EXPORTED. If no variable list is provided, all globals are unexported, and .MAKE.EXPORTED deleted. .unexport-env Unexport all globals previously exported and clear the environ- ment inherited from the parent. This operation causes a memory leak of the original environment, so should be used sparingly. Testing for .MAKE.LEVEL being 0 would make sense. Also note that any variables which originated in the parent environment should be explicitly preserved if desired. For example: .if ${.MAKE.LEVEL} == 0 PATH := ${PATH} .unexport-env .export PATH .endif Would result in an environment containing only `PATH', which is the minimal useful environment. Actually `.MAKE.LEVEL' is also pushed into the new environment. Messages The directives for printing messages to the output are: .info message The message is printed along with the name of the makefile and line number. .warning message The message prefixed by `warning:' is printed along with the name of the makefile and line number. .error message The message is printed along with the name of the makefile and line number, bmake exits immediately. Conditionals The directives for conditionals are: .if [!]expression [operator expression ...] Test the value of an expression. .ifdef [!]variable [operator variable ...] Test whether a variable is defined. .ifndef [!]variable [operator variable ...] Test whether a variable is not defined. .ifmake [!]target [operator target ...] Test the target being requested. .ifnmake [!]target [operator target ...] Test the target being requested. .else Reverse the sense of the last conditional. .elif [!]expression [operator expression ...] A combination of `.else' followed by `.if'. .elifdef [!]variable [operator variable ...] A combination of `.else' followed by `.ifdef'. .elifndef [!]variable [operator variable ...] A combination of `.else' followed by `.ifndef'. .elifmake [!]target [operator target ...] A combination of `.else' followed by `.ifmake'. .elifnmake [!]target [operator target ...] A combination of `.else' followed by `.ifnmake'. .endif End the body of the conditional. The operator may be any one of the following: || Logical OR. && Logical AND; of higher precedence than `||'. bmake only evaluates a conditional as far as is necessary to determine its value. Parentheses can be used to override the operator precedence. - The boolean operator `!' may be used to logically negate an entire condi- - tional. It is of higher precedence than `&&'. + The boolean operator `!' may be used to logically negate an expression, + typically a function call. It is of higher precedence than `&&'. The value of expression may be any of the following function call expres- sions: defined(varname) Evaluates to true if the variable varname has been defined. make(target) Evaluates to true if the target was specified as part of bmake's command line or was declared the default target (either implic- itly or explicitly, see .MAIN) before the line containing the conditional. empty(varname[:modifiers]) Evaluates to true if the expansion of the variable, after apply- ing the modifiers, results in an empty string. exists(pathname) Evaluates to true if the given pathname exists. If relative, the pathname is searched for on the system search path (see .PATH). target(target) Evaluates to true if the target has been defined. commands(target) Evaluates to true if the target has been defined and has commands associated with it. Expression may also be an arithmetic or string comparison. Variable ex- pansion is performed on both sides of the comparison. If both sides are numeric and neither is enclosed in quotes, the comparison is done numeri- - cally, otherwise lexicographically. A string is interpreted as hexadeci- - mal integer if it is preceded by 0x, otherwise it is a decimal floating- - point number; octal numbers are not supported. + cally, otherwise lexicographically. A string is interpreted as a hexa- + decimal integer if it is preceded by 0x, otherwise it is interpreted as a + decimal floating-point number; octal numbers are not supported. All comparisons may use the operators `==' and `!='. Numeric comparisons may also use the operators `<', `<=', `>' and `>='. If the comparison has neither a comparison operator nor a right side, the expression evaluates to true if it is nonempty and its numeric value (if any) is not zero. When bmake is evaluating one of these conditional expressions, and it en- - counters a (whitespace separated) word it doesn't recognize, either the + counters a (whitespace-separated) word it doesn't recognize, either the "make" or "defined" function is applied to it, depending on the form of the conditional. If the form is `.ifdef', `.ifndef' or `.if', the "defined" function is applied. Similarly, if the form is `.ifmake' or `.ifnmake', the "make" function is applied. If the conditional evaluates to true, parsing of the makefile continues - as before. If it evaluates to false, the following lines are skipped. - In both cases, this continues until the corresponding `.else' or `.endif' - is found. + as before. If it evaluates to false, the following lines until the cor- + responding `.elif' variant, `.else' or `.endif' are skipped. For loops For loops are typically used to apply a set of rules to a list of files. The syntax of a for loop is: .for variable [variable ...] in expression <make-lines> .endfor The expression is expanded and then split into words. On each iteration of the loop, one word is taken and assigned to each variable, in order, and these variables are substituted into the make-lines inside the body of the for loop. The number of words must come out even; that is, if there are three iteration variables, the number of words provided must be a multiple of three. If `.break' is encountered within a .for loop, it causes early termina- tion of the loop, otherwise a parse error. Other directives .undef variable ... Un-define the specified global variables. Only global variables can be un-defined. COMMENTS Comments begin with a hash (`#') character, anywhere but in a shell com- mand line, and continue to the end of an unescaped new line. SPECIAL SOURCES (ATTRIBUTES) .EXEC Target is never out of date, but always execute commands any- way. .IGNORE Ignore any errors from the commands associated with this tar- get, exactly as if they all were preceded by a dash (`-'). .MADE Mark all sources of this target as being up to date. .MAKE Execute the commands associated with this target even if the -n or -t options were specified. Normally used to mark recursive bmakes. .META Create a meta file for the target, even if it is flagged as .PHONY, .MAKE, or .SPECIAL. Usage in conjunction with .MAKE is the most likely case. In "meta" mode, the target is out-of- date if the meta file is missing. .NOMETA Do not create a meta file for the target. Meta files are also not created for .PHONY, .MAKE, or .SPECIAL targets. .NOMETA_CMP Ignore differences in commands when deciding if target is out of date. This is useful if the command contains a value which always changes. If the number of commands change, though, the target is still considered out of date. The same effect ap- plies to any command line that uses the variable .OODATE, which can be used for that purpose even when not otherwise needed or desired: skip-compare-for-some: @echo this is compared @echo this is not ${.OODATE:M.NOMETA_CMP} @echo this is also compared The :M pattern suppresses any expansion of the unwanted vari- able. .NOPATH Do not search for the target in the directories specified by .PATH. .NOTMAIN Normally bmake selects the first target it encounters as the default target to be built if no target was specified. This source prevents this target from being selected. .OPTIONAL If a target is marked with this attribute and bmake can't fig- ure out how to create it, it ignores this fact and assumes the file isn't needed or already exists. .PHONY The target does not correspond to an actual file; it is always considered to be out of date, and is not created with the -t option. Suffix-transformation rules are not applied to .PHONY targets. .PRECIOUS When bmake is interrupted, it normally removes any partially made targets. This source prevents the target from being re- moved. .RECURSIVE Synonym for .MAKE. .SILENT Do not echo any of the commands associated with this target, exactly as if they all were preceded by an at sign (`@'). .USE Turn the target into bmake's version of a macro. When the tar- get is used as a source for another target, the other target acquires the commands, sources, and attributes (except for .USE) of the source. If the target already has commands, the .USE target's commands are appended to them. .USEBEFORE Like .USE, but instead of appending, prepend the .USEBEFORE target commands to the target. .WAIT If .WAIT appears in a dependency line, the sources that precede it are made before the sources that succeed it in the line. Since the dependents of files are not made until the file it- self could be made, this also stops the dependents being built unless they are needed for another branch of the dependency tree. So given: x: a .WAIT b echo x a: echo a b: b1 echo b b1: echo b1 the output is always `a', `b1', `b', `x'. The ordering imposed by .WAIT is only relevant for parallel makes. SPECIAL TARGETS Special targets may not be included with other targets, i.e. they must be the only target specified. .BEGIN Any command lines attached to this target are executed before anything else is done. .DEFAULT This is sort of a .USE rule for any target (that was used only as a source) that bmake can't figure out any other way to cre- ate. Only the shell script is used. The .IMPSRC variable of a target that inherits .DEFAULT's commands is set to the target's own name. .DELETE_ON_ERROR If this target is present in the makefile, it globally causes make to delete targets whose commands fail. (By default, only targets whose commands are interrupted during execution are deleted. This is the historical behavior.) This setting can be used to help prevent half-finished or malformed targets from be- ing left around and corrupting future rebuilds. .END Any command lines attached to this target are executed after ev- erything else is done successfully. .ERROR Any command lines attached to this target are executed when an- other target fails. The .ERROR_TARGET variable is set to the target that failed. See also MAKE_PRINT_VAR_ON_ERROR. .IGNORE Mark each of the sources with the .IGNORE attribute. If no sources are specified, this is the equivalent of specifying the -i option. .INTERRUPT If bmake is interrupted, the commands for this target are exe- cuted. .MAIN If no target is specified when bmake is invoked, this target is built. .MAKEFLAGS This target provides a way to specify flags for bmake at the time when the makefiles are read. The flags are as if typed to the shell, though the -f option has no effect. .NOPATH Apply the .NOPATH attribute to any specified sources. .NOTPARALLEL Disable parallel mode. .NO_PARALLEL Synonym for .NOTPARALLEL, for compatibility with other pmake variants. .NOREADONLY clear the read-only attribute from the global variables speci- fied as sources. .OBJDIR The source is a new value for `.OBJDIR'. If it exists, bmake changes the current working directory to it and updates the value of `.OBJDIR'. .ORDER In parallel mode, the named targets are made in sequence. This ordering does not add targets to the list of targets to be made. Since the dependents of a target do not get built until the tar- get itself could be built, unless `a' is built by another part of the dependency graph, the following is a dependency loop: .ORDER: b a b: a .PATH The sources are directories which are to be searched for files not found in the current directory. If no sources are speci- fied, any previously specified directories are removed from the search path. If the source is the special .DOTLAST target, the current working directory is searched last. .PATH.suffix Like .PATH but applies only to files with a particular suffix. The suffix must have been previously declared with .SUFFIXES. .PHONY Apply the .PHONY attribute to any specified sources. .POSIX If this is the first non-comment line in the main makefile, the variable %POSIX is set to the value `1003.2' and the makefile `' is included if it exists, to provide POSIX-compati- ble default rules. If bmake is run with the -r flag, only `posix.mk' contributes to the default rules. .PRECIOUS Apply the .PRECIOUS attribute to any specified sources. If no sources are specified, the .PRECIOUS attribute is applied to ev- ery target in the file. .READONLY set the read-only attribute on the global variables specified as sources. .SHELL Sets the shell that bmake uses to execute commands in jobs mode. The sources are a set of field=value pairs. name This is the minimal specification, used to select one of the built-in shell specs; sh, ksh, and csh. path Specifies the absolute path to the shell. hasErrCtl Indicates whether the shell supports exit on error. check The command to turn on error checking. ignore The command to disable error checking. echo The command to turn on echoing of commands executed. quiet The command to turn off echoing of commands exe- cuted. filter The output to filter after issuing the quiet com- mand. It is typically identical to quiet. errFlag The flag to pass the shell to enable error checking. echoFlag The flag to pass the shell to enable command echo- ing. newline The string literal to pass the shell that results in a single newline character when used outside of any quoting characters. Example: .SHELL: name=ksh path=/bin/ksh hasErrCtl=true \ check="set -e" ignore="set +e" \ echo="set -v" quiet="set +v" filter="set +v" \ echoFlag=v errFlag=e newline="'\n'" .SILENT Apply the .SILENT attribute to any specified sources. If no sources are specified, the .SILENT attribute is applied to every command in the file. .STALE This target gets run when a dependency file contains stale en- tries, having .ALLSRC set to the name of that dependency file. .SUFFIXES Each source specifies a suffix to bmake. If no sources are specified, any previously specified suffixes are deleted. It allows the creation of suffix-transformation rules. Example: .SUFFIXES: .c .o .c.o: cc -o ${.TARGET} -c ${.IMPSRC} .SYSPATH The sources are directories which are to be added to the system include path which bmake searches for makefiles. If no sources are specified, any previously specified directories are removed from the system include path. ENVIRONMENT bmake uses the following environment variables, if they exist: MACHINE, MACHINE_ARCH, MAKE, MAKEFLAGS, MAKEOBJDIR, MAKEOBJDIRPREFIX, MAKESYSPATH, PWD, and TMPDIR. MAKEOBJDIRPREFIX and MAKEOBJDIR may only be set in the environment or on the command line to bmake and not as makefile variables; see the descrip- tion of `.OBJDIR' for more details. FILES .depend list of dependencies makefile first default makefile if no makefile is specified on the command line Makefile second default makefile if no makefile is specified on the command line sys.mk system makefile /usr/share/mk system makefile directory COMPATIBILITY The basic make syntax is compatible between different make variants; how- ever the special variables, variable modifiers and conditionals are not. Older versions An incomplete list of changes in older versions of bmake: The way that .for loop variables are substituted changed after NetBSD 5.0 so that they still appear to be variable expansions. In particular this stops them being treated as syntax, and removes some obscure problems us- ing them in .if statements. The way that parallel makes are scheduled changed in NetBSD 4.0 so that .ORDER and .WAIT apply recursively to the dependent nodes. The algo- rithms used may change again in the future. Other make dialects Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not sup- port most of the features of bmake as described in this manual. Most no- tably: +o The .WAIT and .ORDER declarations and most functionality per- taining to parallelization. (GNU make supports parallelization but lacks the features needed to control it effectively.) +o Directives, including for loops and conditionals and most of the forms of include files. (GNU make has its own incompatible and less powerful syntax for conditionals.) +o All built-in variables that begin with a dot. +o Most of the special sources and targets that begin with a dot, with the notable exception of .PHONY, .PRECIOUS, and .SUFFIXES. +o Variable modifiers, except for the `:old=new' string substitu- tion, which does not portably support globbing with `%' and historically only works on declared suffixes. +o The $> variable even in its short form; most makes support this functionality but its name varies. Some features are somewhat more portable, such as assignment with +=, ?=, and !=. The .PATH functionality is based on an older feature VPATH found in GNU make and many versions of SVR4 make; however, historically its be- havior is too ill-defined (and too buggy) to rely upon. The $@ and $< variables are more or less universally portable, as is the $(MAKE) variable. Basic use of suffix rules (for files only in the cur- rent directory, not trying to chain transformations together, etc.) is also reasonably portable. SEE ALSO mkdep(1) HISTORY bmake is derived from NetBSD make(1). It uses autoconf to facilitate portability to other platforms. A make command appeared in Version 7 AT&T UNIX. This make implementation is based on Adam de Boor's pmake program, which was written for Sprite at Berkeley. It was designed to be a parallel distributed make running jobs on different machines using a daemon called "customs". Historically the target/dependency FRC has been used to FoRCe rebuilding (since the target/dependency does not exist ... unless someone creates an FRC file). BUGS The make syntax is difficult to parse. For instance, finding the end of a variable's use should involve scanning each of the modifiers, using the correct terminator for each field. In many places make just counts {} and () in order to find the end of a variable expansion. There is no way of escaping a space character in a filename. In jobs mode, when a target fails; make will put an error token into the job token pool. This will cause all other instances of make using that token pool to abort the build and exit with error code 6. Sometimes the attempt to suppress a cascade of unnecessary errors, can result in a seemingly unexplained `*** Error code 6' -FreeBSD 13.0 May 10, 2023 FreeBSD 13.0 +FreeBSD 13.0 September 9, 2023 FreeBSD 13.0 diff --git a/contrib/bmake/boot-strap b/contrib/bmake/boot-strap index 8892f2b1c990..f47f0c4fdecd 100755 --- a/contrib/bmake/boot-strap +++ b/contrib/bmake/boot-strap @@ -1,476 +1,476 @@ : # NAME: # boot-strap # # SYNOPSIS: # boot-strap ["options"] # boot-strap --prefix=/opt --install # boot-strap --prefix=$HOME --install-host-target -DWITH_PROG_VERSION # boot-strap ["options"] op=build # boot-strap ["options"] op=install # # DESCRIPTION: # This script is used to configure/build bmake it builds for # each host-target in a different subdir to keep the src clean. # There is no requirement for an existing make(1). # # On successful completion if no '--install' flag is given, # it echos a command to do installation. # # The variable "op" defaults to 'all', and is affected by # '--install' flag as above. # Other values include: # # configure # Just run 'configure' # # build # If 'configure' has not been done, do it, then # run the build script, and finally 'test'. # # install # If 'build' has not been done, do it, 'test' then # install. # # clean # attempt to clean up # # test # run the unit-tests.

Its input is a list of specifications as to the files upon which programs and other files depend. If no .Fl f Ar makefile option is given, .Nm tries to open .Sq Pa makefile then .Sq Pa Makefile in order to find the specifications. If the file .Sq Pa .depend exists, it is read, see .Xr mkdep 1 . .Pp This manual page is intended as a reference document only. For a more thorough description of .Nm and makefiles, please refer to .%T "PMake \- A Tutorial" (from 1993). .Pp .Nm prepends the contents of the .Ev MAKEFLAGS environment variable to the command line arguments before parsing them. .Pp The options are as follows: .Bl -tag -width Ds .It Fl B Try to be backwards compatible by executing a single shell per command and by making the sources of a dependency line in sequence. .It Fl C Ar directory Change to .Ar directory before reading the makefiles or doing anything else. If multiple .Fl C options are specified, each is interpreted relative to the previous one: .Fl C Pa / Fl C Pa etc is equivalent to .Fl C Pa /etc . .It Fl D Ar variable Define .Ar variable to be 1, in the global scope. .It Fl d Oo Cm \- Oc Ns Ar flags Turn on debugging, and specify which portions of .Nm are to print debugging information. Unless the flags are preceded by .Ql \- , they are added to the .Ev MAKEFLAGS environment variable and are passed on to any child make processes. By default, debugging information is printed to standard error, but this can be changed using the .Cm F debugging flag. The debugging output is always unbuffered; in addition, if debugging is enabled but debugging output is not directed to standard output, the standard output is line buffered. The available .Ar flags are: .Bl -tag -width Ds .It Cm A Print all possible debugging information; equivalent to specifying all of the debugging flags. .It Cm a Print debugging information about archive searching and caching. .It Cm C Print debugging information about the current working directory. .It Cm c Print debugging information about conditional evaluation. .It Cm d Print debugging information about directory searching and caching. .It Cm e Print debugging information about failed commands and targets. .It Cm F Ns Oo Cm \&+ Oc Ns Ar filename Specify where debugging output is written. This must be the last flag, because it consumes the remainder of the argument. If the character immediately after the .Cm F flag is .Ql \&+ , the file is opened in append mode; otherwise the file is overwritten. If the file name is .Ql stdout or .Ql stderr , debugging output is written to the standard output or standard error output respectively (and the .Ql \&+ option has no effect). Otherwise, the output is written to the named file. If the file name ends with .Ql .%d , the .Ql %d is replaced by the pid. .It Cm f Print debugging information about loop evaluation. .It Cm g1 Print the input graph before making anything. .It Cm g2 Print the input graph after making everything, or before exiting on error. .It Cm g3 Print the input graph before exiting on error. .It Cm h Print debugging information about hash table operations. .It Cm j Print debugging information about running multiple shells. .It Cm L Turn on lint checks. This throws errors for variable assignments that do not parse correctly, at the time of assignment, so the file and line number are available. .It Cm l Print commands in Makefiles regardless of whether or not they are prefixed by .Ql @ or other .Dq quiet flags. Also known as .Dq loud behavior. .It Cm M Print debugging information about .Dq meta mode decisions about targets. .It Cm m Print debugging information about making targets, including modification dates. .It Cm n Don't delete the temporary command scripts created when running commands. These temporary scripts are created in the directory referred to by the .Ev TMPDIR environment variable, or in .Pa /tmp if .Ev TMPDIR is unset or set to the empty string. The temporary scripts are created by .Xr mkstemp 3 , and have names of the form .Pa makeXXXXXX . .Em NOTE : This can create many files in .Ev TMPDIR or .Pa /tmp , so use with care. .It Cm p Print debugging information about makefile parsing. .It Cm s Print debugging information about suffix-transformation rules. .It Cm t Print debugging information about target list maintenance. .It Cm V Force the .Fl V option to print raw values of variables, overriding the default behavior set via .Va .MAKE.EXPAND_VARIABLES . .It Cm v Print debugging information about variable assignment and expansion. .It Cm x Run shell commands with .Fl x so the actual commands are printed as they are executed. .El .It Fl e Let environment variables override global variables within makefiles. .It Fl f Ar makefile Specify a makefile to read instead of the default .Pa makefile or .Pa Makefile . If .Ar makefile is .Ql \&- , standard input is read. Multiple makefiles may be specified, and are read in the order specified. .It Fl I Ar directory Specify a directory in which to search for makefiles and included makefiles. The system makefile directory (or directories, see the .Fl m option) is automatically included as part of this list. .It Fl i Ignore non-zero exit of shell commands in the makefile. Equivalent to specifying .Ql \&- before each command line in the makefile. .It Fl J Ar private This option should .Em not be specified by the user. .Pp When the .Fl j option is in use in a recursive build, this option is passed by a make to child makes to allow all the make processes in the build to cooperate to avoid overloading the system. .It Fl j Ar max_jobs Specify the maximum number of jobs that .Nm may have running at any one time. +If +.Ar max_jobs +is a floating point number, or ends with +.Ql C , +then the value is multiplied by the number of CPUs reported online by +.Xr sysconf 3 . The value of .Ar max_jobs is saved in .Va .MAKE.JOBS . Turns compatibility mode off, unless the .Fl B option is also specified. When compatibility mode is off, all commands associated with a target are executed in a single shell invocation as opposed to the traditional one shell invocation per line. This can break traditional scripts which change directories on each command invocation and then expect to start with a fresh environment on the next line. It is more efficient to correct the scripts rather than turn backwards compatibility on. .Pp A job token pool with .Ar max_jobs tokens is used to control the total number of jobs running. Each instance of .Nm will wait for a token from the pool before running a new job. .It Fl k Continue processing after errors are encountered, but only on those targets that do not depend on the target whose creation caused the error. .It Fl m Ar directory Specify a directory in which to search for .Pa sys.mk and makefiles included via the .Li \&< Ns Ar file Ns Li \&> Ns -style include statement. The .Fl m option can be used multiple times to form a search path. This path overrides the default system include path .Pa /usr/share/mk . Furthermore, the system include path is appended to the search path used for .Li \*q Ns Ar file Ns Li \*q Ns -style include statements (see the .Fl I option). The system include path can be referenced via the read-only variable .Va .SYSPATH . .Pp If a directory name in the .Fl m argument (or the .Ev MAKESYSPATH environment variable) starts with the string .Ql \&.../ , .Nm searches for the specified file or directory named in the remaining part of the argument string. The search starts with the current directory and then works upward towards the root of the file system. If the search is successful, the resulting directory replaces the .Ql \&.../ specification in the .Fl m argument. This feature allows .Nm to easily search in the current source tree for customized .Pa sys.mk files (e.g., by using .Ql \&.../mk/sys.mk as an argument). .It Fl n Display the commands that would have been executed, but do not actually execute them unless the target depends on the .Va .MAKE special source (see below) or the command is prefixed with .Sq Cm + . .It Fl N Display the commands that would have been executed, but do not actually execute any of them; useful for debugging top-level makefiles without descending into subdirectories. .It Fl q Do not execute any commands, instead exit 0 if the specified targets are up to date, and 1 otherwise. .It Fl r Do not use the built-in rules specified in the system makefile. .It Fl S Stop processing if an error is encountered. This is the default behavior and the opposite of .Fl k . .It Fl s Do not echo any commands as they are executed. Equivalent to specifying .Sq Ic @ before each command line in the makefile. .It Fl T Ar tracefile When used with the .Fl j flag, append a trace record to .Ar tracefile for each job started and completed. .It Fl t Rather than re-building a target as specified in the makefile, create it or update its modification time to make it appear up-to-date. .It Fl V Ar variable Print the value of .Ar variable . Do not build any targets. Multiple instances of this option may be specified; the variables are printed one per line, with a blank line for each null or undefined variable. The value printed is extracted from the global scope after all makefiles have been read. .Pp By default, the raw variable contents (which may include additional unexpanded variable references) are shown. If .Ar variable contains a .Ql \&$ , it is not interpreted as a variable name but rather as an expression. Its value is expanded before printing. The value is also expanded before printing if .Va .MAKE.EXPAND_VARIABLES is set to true and the .Fl dV option has not been used to override it. .Pp Note that loop-local and target-local variables, as well as values taken temporarily by global variables during makefile processing, are not accessible via this option. The .Fl dv debug mode can be used to see these at the cost of generating substantial extraneous output. .It Fl v Ar variable Like .Fl V , but all printed variables are always expanded to their complete value. The last occurrence of .Fl V or .Fl v decides whether all variables are expanded or not. .It Fl W Treat any warnings during makefile parsing as errors. .It Fl w Print entering and leaving directory messages, pre and post processing. .It Fl X Don't export variables passed on the command line to the environment individually. Variables passed on the command line are still exported via the .Ev MAKEFLAGS environment variable. This option may be useful on systems which have a small limit on the size of command arguments. .It Ar variable\| Ns Cm \&= Ns Ar value Set the value of the variable .Ar variable to .Ar value . Normally, all values passed on the command line are also exported to sub-makes in the environment. The .Fl X flag disables this behavior. Variable assignments should follow options for POSIX compatibility but no ordering is enforced. .El .Pp There are several different types of lines in a makefile: dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, other directives, and comments. .Pp Lines may be continued from one line to the next by ending them with a backslash .Pq Ql \e . The trailing newline character and initial whitespace on the following line are compressed into a single space. .Sh FILE DEPENDENCY SPECIFICATIONS Dependency lines consist of one or more targets, an operator, and zero or more sources. This creates a relationship where the targets .Dq depend on the sources and are customarily created from them. A target is considered out of date if it does not exist, or if its modification time is less than that of any of its sources. An out-of-date target is re-created, but not until all sources have been examined and themselves re-created as needed. Three operators may be used: .Bl -tag -width flag .It Ic \&: Many dependency lines may name this target but only one may have attached shell commands. All sources named in all dependency lines are considered together, and if needed the attached shell commands are run to create or re-create the target. If .Nm is interrupted, the target is removed. .It Ic \&! The same, but the target is always re-created whether or not it is out of date. .It Ic \&:: Any dependency line may have attached shell commands, but each one is handled independently: its sources are considered and the attached shell commands are run if the target is out of date with respect to (only) those sources. Thus, different groups of the attached shell commands may be run depending on the circumstances. Furthermore, unlike .Ic \&: , for dependency lines with no sources, the attached shell commands are always run. Also unlike .Ic \&: , the target is not removed if .Nm is interrupted. .El .Pp All dependency lines mentioning a particular target must use the same operator. .Pp Targets and sources may contain the shell wildcard values .Ql \&? , .Ql * , .Ql [] , and .Ql {} . The values .Ql \&? , .Ql * , and .Ql [] may only be used as part of the final component of the target or source, and only match existing files. The value .Ql {} need not necessarily be used to describe existing files. Expansion is in directory order, not alphabetically as done in the shell. .Sh SHELL COMMANDS Each target may have associated with it one or more lines of shell commands, normally used to create the target. Each of the lines in this script .Em must be preceded by a tab. (For historical reasons, spaces are not accepted.) While targets can occur in many dependency lines if desired, by default only one of these rules may be followed by a creation script. If the .Sq Ic \&:: operator is used, however, all rules may include scripts, and the respective scripts are executed in the order found. .Pp Each line is treated as a separate shell command, unless the end of line is escaped with a backslash .Ql \e , in which case that line and the next are combined. If the first characters of the command are any combination of .Sq Ic @ , .Sq Ic + , or .Sq Ic \- , the command is treated specially. .Bl -tag -offset indent -width indent .It Ic @ causes the command not to be echoed before it is executed. .It Ic + causes the command to be executed even when .Fl n is given. This is similar to the effect of the .Va .MAKE special source, except that the effect can be limited to a single line of a script. .It Ic \- in compatibility mode causes any non-zero exit status of the command line to be ignored. .El .Pp When .Nm is run in jobs mode with .Fl j Ar max_jobs , the entire script for the target is fed to a single instance of the shell. In compatibility (non-jobs) mode, each command is run in a separate process. If the command contains any shell meta characters .Pq Ql #=|^(){};&<>*?[]:$`\e\en , it is passed to the shell; otherwise .Nm attempts direct execution. If a line starts with .Sq Ic \- and the shell has ErrCtl enabled, failure of the command line is ignored as in compatibility mode. Otherwise .Sq Ic \- affects the entire job; the script stops at the first command line that fails, but the target is not deemed to have failed. .Pp Makefiles should be written so that the mode of .Nm operation does not change their behavior. For example, any command which uses .Dq cd or .Dq chdir without the intention of changing the directory for subsequent commands should be put in parentheses so it executes in a subshell. To force the use of a single shell, escape the line breaks so as to make the whole script one command. For example: .Bd -literal -offset indent avoid-chdir-side-effects: @echo "Building $@ in $$(pwd)" @(cd ${.CURDIR} && ${MAKE} $@) @echo "Back in $$(pwd)" ensure-one-shell-regardless-of-mode: @echo "Building $@ in $$(pwd)"; \e (cd ${.CURDIR} && ${MAKE} $@); \e echo "Back in $$(pwd)" .Ed .Pp Since .Nm changes the current working directory to .Sq Va .OBJDIR before executing any targets, each child process starts with that as its current working directory. .Sh VARIABLE ASSIGNMENTS Variables in make behave much like macros in the C preprocessor. .Pp Variable assignments have the form .Sq Ar NAME Ar op Ar value , where: .Bl -tag -offset Ds -width Ds .It Ar NAME is a single-word variable name, consisting, by tradition, of all upper-case letters, .It Ar op is one of the variable assignment operators described below, and .It Ar value is interpreted according to the variable assignment operator. .El .Pp Whitespace around .Ar NAME , .Ar op and .Ar value is discarded. .Ss Variable assignment operators The five operators that assign values to variables are: .Bl -tag -width Ds .It Ic \&= Assign the value to the variable. Any previous value is overwritten. .It Ic \&+= Append the value to the current value of the variable, separating them by a single space. .It Ic \&?= Assign the value to the variable if it is not already defined. .It Ic \&:= Expand the value, then assign it to the variable. .Pp .Em NOTE : References to undefined variables are .Em not expanded. This can cause problems when variable modifiers are used. .\" See var-op-expand.mk, the section with LATER and INDIRECT. .It Ic \&!= Expand the value and pass it to the shell for execution, then assign the output from the child's standard output to the variable. Any newlines in the result are replaced with spaces. .El .Ss Expansion of variables In most contexts where variables are expanded, .Ql \&$$ expands to a single dollar sign. In other contexts (most variable modifiers, string literals in conditions), .Ql \&\e$ expands to a single dollar sign. .Pp References to variables have the form .Cm \&${ Ns Ar name Ns Oo Ns Cm \&: Ns Ar modifiers Oc Ns Cm \&} or .Cm \&$( Ns Ar name Ns Oo Ns Cm \&: Ns Ar modifiers Oc Ns Cm \&) . If the variable name consists of only a single character and the expression contains no modifiers, the surrounding curly braces or parentheses are not required. This shorter form is not recommended. .Pp If the variable name contains a dollar, the name itself is expanded first. This allows almost arbitrary variable names, however names containing dollar, braces, parentheses or whitespace are really best avoided. .Pp If the result of expanding a nested variable expression contains a dollar sign .Pq Ql \&$ , the result is subject to further expansion. .Pp Variable substitution occurs at four distinct times, depending on where the variable is being used. .Bl -enum .It Variables in dependency lines are expanded as the line is read. .It Variables in conditionals are expanded individually, but only as far as necessary to determine the result of the conditional. .It Variables in shell commands are expanded when the shell command is executed. .It .Ic .for loop index variables are expanded on each loop iteration. Note that other variables are not expanded when composing the body of a loop, so the following example code: .Bd -literal -offset indent \&.for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} \&.endfor all: @echo ${a} @echo ${b} .Ed .Pp prints: .Bd -literal -offset indent 1 2 3 3 3 3 .Ed .Pp After the loop is executed: .Bl -tag -offset indent -width indent .It Va a contains .Ql ${:U1} ${:U2} ${:U3} , which expands to .Ql 1 2 3 . .It Va j contains .Ql ${:U3} , which expands to .Ql 3 . .It Va b contains .Ql ${j} ${j} ${j} , which expands to .Ql ${:U3} ${:U3} ${:U3} and further to .Ql 3 3 3 . .El .El .Ss Variable classes The four different classes of variables (in order of increasing precedence) are: .Bl -tag -width Ds .It Environment variables Variables defined as part of .Nm Ns 's environment. .It Global variables Variables defined in the makefile or in included makefiles. .It Command line variables Variables defined as part of the command line. .It Local variables Variables that are defined specific to a certain target. .El .Pp Local variables can be set on a dependency line, unless .Va .MAKE.TARGET_LOCAL_VARIABLES is set to .Ql false . The rest of the line (which already has had global variables expanded) is the variable value. For example: .Bd -literal -offset indent COMPILER_WRAPPERS= ccache distcc icecc ${OBJS}: .MAKE.META.CMP_FILTER=${COMPILER_WRAPPERS:S,^,N,} .Ed .Pp Only the targets .Ql ${OBJS} are impacted by that filter (in .Dq meta mode) and simply enabling/disabling any of the compiler wrappers does not render all of those targets out-of-date. .Pp .Em NOTE : target-local variable assignments behave differently in that; .Bl -tag -width Ds -offset indent .It Ic \&+= Only appends to a previous local assignment for the same target and variable. .It Ic \&:= Is redundant with respect to global variables, which have already been expanded. .El .Pp The seven built-in local variables are: .Bl -tag -width ".Va .ARCHIVE" -offset indent .It Va .ALLSRC The list of all sources for this target; also known as .Sq Va \&> . .It Va .ARCHIVE The name of the archive file; also known as .Sq Va \&! . .It Va .IMPSRC In suffix-transformation rules, the name/path of the source from which the target is to be transformed (the .Dq implied source); also known as .Sq Va \&< . It is not defined in explicit rules. .It Va .MEMBER The name of the archive member; also known as .Sq Va % . .It Va .OODATE The list of sources for this target that were deemed out-of-date; also known as .Sq Va \&? . .It Va .PREFIX The name of the target with suffix (if declared in .Ic .SUFFIXES ) removed; also known as .Sq Va * . .It Va .TARGET The name of the target; also known as .Sq Va @ . For compatibility with other makes this is an alias for .Va .ARCHIVE in archive member rules. .El .Pp The shorter forms .Po .Sq Va \&> , .Sq Va \&! , .Sq Va \&< , .Sq Va \&% , .Sq Va \&? , .Sq Va \&* , and .Sq Va \&@ .Pc are permitted for backward compatibility with historical makefiles and legacy POSIX make and are not recommended. .Pp Variants of these variables with the punctuation followed immediately by .Ql D or .Ql F , e.g.\& .Ql $(@D) , are legacy forms equivalent to using the .Ql :H and .Ql :T modifiers. These forms are accepted for compatibility with .At V makefiles and POSIX but are not recommended. .Pp Four of the local variables may be used in sources on dependency lines because they expand to the proper value for each target on the line. These variables are .Sq Va .TARGET , .Sq Va .PREFIX , .Sq Va .ARCHIVE , and .Sq Va .MEMBER . .Ss Additional built-in variables In addition, .Nm sets or knows about the following variables: .Bl -tag .\" NB: This list is sorted case-insensitive, ignoring punctuation. .\" NB: To find all built-in variables in make's source code, .\" NB: search for Var_*, Global_*, SetVarObjdir, GetBooleanExpr, .\" NB: and the implementation of Var_SetWithFlags. .\" NB: Last synced on 2023-01-01. .It Va .ALLTARGETS The list of all targets encountered in the makefiles. If evaluated during makefile parsing, lists only those targets encountered thus far. .It Va .CURDIR A path to the directory where .Nm was executed. Refer to the description of .Sq Va PWD for more details. .It Va .ERROR_CMD Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_CWD Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_META_FILE Is used in error handling in .Dq meta mode, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .ERROR_TARGET Is used in error handling, see .Va MAKE_PRINT_VAR_ON_ERROR . .It Va .INCLUDEDFROMDIR The directory of the file this makefile was included from. .It Va .INCLUDEDFROMFILE The filename of the file this makefile was included from. .\" .INCLUDES is intentionally undocumented, as it is obsolete. .\" .LIBS is intentionally undocumented, as it is obsolete. .It Va MACHINE The machine hardware name, see .Xr uname 1 . .It Va MACHINE_ARCH The machine processor architecture name, see .Xr uname 1 . .It Va MAKE The name that .Nm was executed with .Pq Va argv[0] . .It Va .MAKE The same as .Va MAKE , for compatibility. The preferred variable to use is the environment variable .Ev MAKE because it is more compatible with other make variants and cannot be confused with the special target with the same name. .It Va .MAKE.ALWAYS_PASS_JOB_QUEUE Tells .Nm whether to pass the descriptors of the job token queue even if the target is not tagged with .Ic .MAKE The default is .Ql Pa yes for backwards compatability with .Fx 9.0 and earlier. .\" '.MAKE.cmd_filtered' is intentionally undocumented, .\" as it is an internal implementation detail. .It Va .MAKE.DEPENDFILE Names the makefile (default .Sq Pa .depend ) from which generated dependencies are read. .It Va .MAKE.DIE_QUIETLY If set to .Ql true , do not print error information at the end. .It Va .MAKE.EXPAND_VARIABLES A boolean that controls the default behavior of the .Fl V option. If true, variable values printed with .Fl V are fully expanded; if false, the raw variable contents (which may include additional unexpanded variable references) are shown. .It Va .MAKE.EXPORTED The list of variables exported by .Nm . .It Va MAKEFILE The top-level makefile that is currently read, as given in the command line. .It Va .MAKEFLAGS The environment variable .Sq Ev MAKEFLAGS may contain anything that may be specified on .Nm Ns 's command line. Anything specified on .Nm Ns 's command line is appended to the .Va .MAKEFLAGS variable, which is then added to the environment for all programs that .Nm executes. .It Va .MAKE.GID The numeric group ID of the user running .Nm . It is read-only. .It Va .MAKE.JOB.PREFIX If .Nm is run with .Fl j , the output for each target is prefixed with a token .Dl --- Ar target Li --- the first part of which can be controlled via .Va .MAKE.JOB.PREFIX . If .Va .MAKE.JOB.PREFIX is empty, no token is printed. For example, setting .Va .MAKE.JOB.PREFIX to .Ql ${.newline}---${.MAKE:T}[${.MAKE.PID}] would produce tokens like .Dl ---make[1234] Ar target Li --- making it easier to track the degree of parallelism being achieved. .It Va .MAKE.JOBS The argument to the .Fl j option. +.It Va .MAKE.JOBS.C +A read-only boolean that indicates whether the +.Fl j +option supports use of +.Ql C . .It Va .MAKE.LEVEL The recursion depth of .Nm . The top-level instance of .Nm has level 0, and each child make has its parent level plus 1. This allows tests like: .Li .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the top-level instance of .Nm . .It Va .MAKE.LEVEL.ENV The name of the environment variable that stores the level of nested calls to .Nm . .It Va .MAKE.MAKEFILE_PREFERENCE The ordered list of makefile names (default .Sq Pa makefile , .Sq Pa Makefile ) that .Nm looks for. .It Va .MAKE.MAKEFILES The list of makefiles read by .Nm , which is useful for tracking dependencies. Each makefile is recorded only once, regardless of the number of times read. .It Va .MAKE.META.BAILIWICK In .Dq meta mode, provides a list of prefixes which match the directories controlled by .Nm . If a file that was generated outside of .Va .OBJDIR but within said bailiwick is missing, the current target is considered out-of-date. .It Va .MAKE.META.CMP_FILTER In .Dq meta mode, it can (very rarely!) be useful to filter command lines before comparison. This variable can be set to a set of modifiers that are applied to each line of the old and new command that differ, if the filtered commands still differ, the target is considered out-of-date. .It Va .MAKE.META.CREATED In .Dq meta mode, this variable contains a list of all the meta files updated. If not empty, it can be used to trigger processing of .Va .MAKE.META.FILES . .It Va .MAKE.META.FILES In .Dq meta mode, this variable contains a list of all the meta files used (updated or not). This list can be used to process the meta files to extract dependency information. .It Va .MAKE.META.IGNORE_FILTER Provides a list of variable modifiers to apply to each pathname. Ignore if the expansion is an empty string. .It Va .MAKE.META.IGNORE_PATHS Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: .Sq Pa /dev /etc /proc /tmp /var/run /var/tmp .It Va .MAKE.META.IGNORE_PATTERNS Provides a list of patterns to match against pathnames. Ignore any that match. .It Va .MAKE.META.PREFIX Defines the message printed for each meta file updated in .Dq meta verbose mode. The default value is: .Dl Building ${.TARGET:H:tA}/${.TARGET:T} .It Va .MAKE.MODE Processed after reading all makefiles. Affects the mode that .Nm runs in. It can contain these keywords: .Bl -tag -width indent .It Cm compat Like .Fl B , puts .Nm into .Dq compat mode. .It Cm meta Puts .Nm into .Dq meta mode, where meta files are created for each target to capture the command run, the output generated, and if .Xr filemon 4 is available, the system calls which are of interest to .Nm . The captured output can be useful when diagnosing errors. .It Cm curdirOk= Ns Ar bf By default, .Nm does not create .Pa .meta files in .Sq Va .CURDIR . This can be overridden by setting .Ar bf to a value which represents true. .It Cm missing-meta= Ns Ar bf If .Ar bf is true, a missing .Pa .meta file makes the target out-of-date. .It Cm missing-filemon= Ns Ar bf If .Ar bf is true, missing filemon data makes the target out-of-date. .It Cm nofilemon Do not use .Xr filemon 4 . .It Cm env For debugging, it can be useful to include the environment in the .Pa .meta file. .It Cm verbose If in .Dq meta mode, print a clue about the target being built. This is useful if the build is otherwise running silently. The message printed is the expanded value of .Va .MAKE.META.PREFIX . .It Cm ignore-cmd Some makefiles have commands which are simply not stable. This keyword causes them to be ignored for determining whether a target is out of date in .Dq meta mode. See also .Ic .NOMETA_CMP . .It Cm silent= Ns Ar bf If .Ar bf is true, when a .meta file is created, mark the target .Ic .SILENT . .It Cm randomize-targets In both compat and parallel mode, do not make the targets in the usual order, but instead randomize their order. This mode can be used to detect undeclared dependencies between files. .El .It Va MAKEOBJDIR Used to create files in a separate directory, see .Va .OBJDIR . .It Va MAKE_OBJDIR_CHECK_WRITABLE Used to force a separate directory for the created files, even if that directory is not writable, see .Va .OBJDIR . .It Va MAKEOBJDIRPREFIX Used to create files in a separate directory, see .Va .OBJDIR . .It Va .MAKE.OS The name of the operating system, see .Xr uname 1 . It is read-only. .It Va .MAKEOVERRIDES This variable is used to record the names of variables assigned to on the command line, so that they may be exported as part of .Sq Ev MAKEFLAGS . This behavior can be disabled by assigning an empty value to .Sq Va .MAKEOVERRIDES within a makefile. Extra variables can be exported from a makefile by appending their names to .Sq Va .MAKEOVERRIDES . .Sq Ev MAKEFLAGS is re-exported whenever .Sq Va .MAKEOVERRIDES is modified. .It Va .MAKE.PATH_FILEMON If .Nm was built with .Xr filemon 4 support, this is set to the path of the device node. This allows makefiles to test for this support. .It Va .MAKE.PID The process ID of .Nm . It is read-only. .It Va .MAKE.PPID The parent process ID of .Nm . It is read-only. .It Va MAKE_PRINT_VAR_ON_ERROR When .Nm stops due to an error, it sets .Sq Va .ERROR_TARGET to the name of the target that failed, .Sq Va .ERROR_CMD to the commands of the failed target, and in .Dq meta mode, it also sets .Sq Va .ERROR_CWD to the .Xr getcwd 3 , and .Sq Va .ERROR_META_FILE to the path of the meta file (if any) describing the failed target. It then prints its name and the value of .Sq Va .CURDIR as well as the value of any variables named in .Sq Va MAKE_PRINT_VAR_ON_ERROR . .It Va .MAKE.SAVE_DOLLARS If true, .Ql $$ are preserved when doing .Ql := assignments. The default is false, for backwards compatibility. Set to true for compatability with other makes. If set to false, .Ql $$ becomes .Ql $ per normal evaluation rules. .It Va .MAKE.TARGET_LOCAL_VARIABLES If set to .Ql false , apparent variable assignments in dependency lines are treated as normal sources. .It Va .MAKE.UID The numeric ID of the user running .Nm . It is read-only. .\" 'MAKE_VERSION' is intentionally undocumented .\" since it is only defined in the bmake distribution, .\" but not in NetBSD's native make. .\" '.meta.%d.lcwd' is intentionally undocumented .\" since it is an internal implementation detail. .\" '.meta.%d.ldir' is intentionally undocumented .\" since it is an internal implementation detail. .\" 'MFLAGS' is intentionally undocumented .\" since it is obsolete. .It Va .newline This variable is simply assigned a newline character as its value. It is read-only. This allows expansions using the .Cm \&:@ modifier to put a newline between iterations of the loop rather than a space. For example, in case of an error, .Nm prints the variable names and their values using: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Va .OBJDIR A path to the directory where the targets are built. Its value is determined by trying to .Xr chdir 2 to the following directories in order and using the first match: .Bl -enum .It .Cm ${MAKEOBJDIRPREFIX} Ns Cm ${.CURDIR} .Pp (Only if .Sq Ev MAKEOBJDIRPREFIX is set in the environment or on the command line.) .It .Cm ${MAKEOBJDIR} .Pp (Only if .Sq Ev MAKEOBJDIR is set in the environment or on the command line.) .It .Cm ${.CURDIR} Ns Pa /obj. Ns Cm ${MACHINE} .It .Cm ${.CURDIR} Ns Pa /obj .It .Pa /usr/obj/ Ns Cm ${.CURDIR} .It .Cm ${.CURDIR} .El .Pp Variable expansion is performed on the value before it is used, so expressions such as .Cm ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with .Sq Ev MAKEOBJDIR . .Pp .Sq Va .OBJDIR may be modified in the makefile via the special target .Sq Ic .OBJDIR . In all cases, .Nm changes to the specified directory if it exists, and sets .Sq Va .OBJDIR and .Sq Va PWD to that directory before executing any targets. .Pp Except in the case of an explicit .Sq Ic .OBJDIR target, .Nm checks that the specified directory is writable and ignores it if not. This check can be skipped by setting the environment variable .Sq Ev MAKE_OBJDIR_CHECK_WRITABLE to .Dq no . .It Va .PARSEDIR The directory name of the current makefile being parsed. .It Va .PARSEFILE The basename of the current makefile being parsed. This variable and .Sq Va .PARSEDIR are both set only while the makefiles are being parsed. To retain their current values, assign them to a variable using assignment with expansion .Sq Cm \&:= . .It Va .PATH The space-separated list of directories that .Nm searches for files. To update this search list, use the special target .Sq Ic .PATH rather than modifying the variable directly. .It Va %POSIX Is set in POSIX mode, see the special .Ql Va .POSIX target. .\" XXX: There is no make variable named 'PWD', .\" XXX: make only reads and writes the environment variable 'PWD'. .It Va PWD Alternate path to the current directory. .Nm normally sets .Sq Va .CURDIR to the canonical path given by .Xr getcwd 3 . However, if the environment variable .Sq Ev PWD is set and gives a path to the current directory, .Nm sets .Sq Va .CURDIR to the value of .Sq Ev PWD instead. This behavior is disabled if .Sq Ev MAKEOBJDIRPREFIX is set or .Sq Ev MAKEOBJDIR contains a variable transform. .Sq Va PWD is set to the value of .Sq Va .OBJDIR for all programs which .Nm executes. .It Va .SHELL The pathname of the shell used to run target scripts. It is read-only. .It Va .SUFFIXES The list of known suffixes. It is read-only. .It Va .SYSPATH The space-separated list of directories that .Nm searches for makefiles, referred to as the system include path. To update this search list, use the special target .Sq Ic .SYSPATH rather than modifying the variable which is read-only. .It Va .TARGETS The list of targets explicitly specified on the command line, if any. .It Va VPATH The colon-separated .Pq Dq \&: list of directories that .Nm searches for files. This variable is supported for compatibility with old make programs only, use .Sq Va .PATH instead. .El .Ss Variable modifiers The general format of a variable expansion is: .Pp .Sm off .D1 Ic \&${ Ar variable\| Oo Ic \&: Ar modifier\| Oo Ic \&: No ... Oc Oc Ic \&} .Sm on .Pp Each modifier begins with a colon. To escape a colon, precede it with a backslash .Ql \e . .Pp A list of indirect modifiers can be specified via a variable, as follows: .Pp .Bd -literal -offset indent .Ar modifier_variable\^ Li \&= Ar modifier Ns Oo Ic \&: Ns No ... Oc .Sm off .Ic \&${ Ar variable Ic \&:${ Ar modifier_variable Ic \&} Oo Ic \&: No ... Oc Ic \&} .Sm on .Ed .Pp In this case, the first modifier in the .Ar modifier_variable does not start with a colon, since that colon already occurs in the referencing variable. If any of the modifiers in the .Ar modifier_variable contains a dollar sign .Pq Ql $ , these must be doubled to avoid early expansion. .Pp Some modifiers interpret the expression value as a single string, others treat the expression value as a whitespace-separated list of words. When splitting a string into words, whitespace can be escaped using double quotes, single quotes and backslashes, like in the shell. The quotes and backslashes are retained in the words. .Pp The supported modifiers are: .Bl -tag -width EEE .It Cm \&:E Replaces each word with its suffix. .It Cm \&:H Replaces each word with its dirname. .It Cm \&:M\| Ns Ar pattern Selects only those words that match .Ar pattern . The standard shell wildcard characters .Pf ( Ql * , .Ql \&? , and .Ql \&[] ) may be used. The wildcard characters may be escaped with a backslash .Pq Ql \e . As a consequence of the way values are split into words, matched, and then joined, the construct .Ql ${VAR:M*} removes all leading and trailing whitespace and normalizes the inter-word spacing to a single space. .It Cm \&:N\| Ns Ar pattern This is the opposite of .Sq Cm \&:M , selecting all words which do .Em not match .Ar pattern . .It Cm \&:O Orders the words lexicographically. .It Cm \&:On Orders the words numerically. A number followed by one of .Ql k , .Ql M or .Ql G is multiplied by the appropriate factor, which is 1024 for .Ql k , 1048576 for .Ql M , or 1073741824 for .Ql G . Both upper- and lower-case letters are accepted. .It Cm \&:Or Orders the words in reverse lexicographical order. .It Cm \&:Orn Orders the words in reverse numerical order. .It Cm \&:Ox Shuffles the words. The results are different each time you are referring to the modified variable; use the assignment with expansion .Sq Cm \&:= to prevent such behavior. For example, .Bd -literal -offset indent LIST= uno due tre quattro RANDOM_LIST= ${LIST:Ox} STATIC_RANDOM_LIST:= ${LIST:Ox} all: @echo "${RANDOM_LIST}" @echo "${RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" @echo "${STATIC_RANDOM_LIST}" .Ed may produce output similar to: .Bd -literal -offset indent quattro due tre uno tre due quattro uno due uno quattro tre due uno quattro tre .Ed .It Cm \&:Q Quotes every shell meta-character in the value, so that it can be passed safely to the shell. .It Cm \&:q Quotes every shell meta-character in the value, and also doubles .Sq $ characters so that it can be passed safely through recursive invocations of .Nm . This is equivalent to .Sq Cm \&:S/\e\&$/&&/g:Q . .It Cm \&:R Replaces each word with everything but its suffix. .It Cm \&:range Ns Oo Cm = Ns Ar count Oc The value is an integer sequence representing the words of the original value, or the supplied .Ar count . .It Cm \&:gmtime Ns Oo Cm = Ns Ar timestamp Oc The value is interpreted as a format string for .Xr strftime 3 , using .Xr gmtime 3 , producing the formatted timestamp. +Note: the +.Ql %s +format should only be used with +.Sq Cm \&:localtime . If a .Ar timestamp value is not provided or is 0, the current time is used. .It Cm \&:hash Computes a 32-bit hash of the value and encodes it as 8 hex digits. .It Cm \&:localtime Ns Oo Cm = Ns Ar timestamp Oc The value is interpreted as a format string for .Xr strftime 3 , using .Xr localtime 3 , producing the formatted timestamp. If a .Ar timestamp value is not provided or is 0, the current time is used. .It Cm \&:mtime Ns Oo Cm = Ns Ar timestamp Oc Call .Xr stat 2 with each word as pathname; use .Ql st_mtime as the new value. If .Xr stat 2 fails; use .Ar timestamp or current time. If .Ar timestamp is set to .Ql error , then .Xr stat 2 failure will cause an error. .It Cm \&:tA Attempts to convert the value to an absolute path using .Xr realpath 3 . If that fails, the value is unchanged. .It Cm \&:tl Converts the value to lower-case letters. .It Cm \&:ts Ns Ar c When joining the words after a modifier that treats the value as words, the words are normally separated by a space. This modifier changes the separator to the character .Ar c . If .Ar c is omitted, no separator is used. The common escapes (including octal numeric codes) work as expected. .It Cm \&:tu Converts the value to upper-case letters. .It Cm \&:tW Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). See also .Sq Cm \&:[*] . .It Cm \&:tw Causes the value to be treated as a list of words. See also .Sq Cm \&:[@] . .Sm off .It Cm \&:S\| No \&/ Ar old_string\| No \&/ Ar new_string\| No \&/ Op Cm 1gW .Sm on Modifies the first occurrence of .Ar old_string in each word of the value, replacing it with .Ar new_string . If a .Ql g is appended to the last delimiter of the pattern, all occurrences in each word are replaced. If a .Ql 1 is appended to the last delimiter of the pattern, only the first occurrence is affected. If a .Ql W is appended to the last delimiter of the pattern, the value is treated as a single word. If .Ar old_string begins with a caret .Pq Ql ^ , .Ar old_string is anchored at the beginning of each word. If .Ar old_string ends with a dollar sign .Pq Ql \&$ , it is anchored at the end of each word. Inside .Ar new_string , an ampersand .Pq Ql & is replaced by .Ar old_string (without the anchoring .Ql ^ or .Ql \&$ ) . Any character may be used as the delimiter for the parts of the modifier string. The anchoring, ampersand and delimiter characters can be escaped with a backslash .Pq Ql \e . .Pp Both .Ar old_string and .Ar new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. .Sm off .It Cm \&:C\| No \&/ Ar pattern\| No \&/ Ar replacement\| No \&/ Op Cm 1gW .Sm on The .Cm \&:C modifier works like the .Cm \&:S modifier except that the old and new strings, instead of being simple strings, are an extended regular expression .Ar pattern (see .Xr regex 3 ) and an .Xr ed 1 Ns \-style .Ar replacement . Normally, the first occurrence of the pattern .Ar pattern in each word of the value is substituted with .Ar replacement . The .Ql 1 modifier causes the substitution to apply to at most one word; the .Ql g modifier causes the substitution to apply to as many instances of the search pattern .Ar pattern as occur in the word or words it is found in; the .Ql W modifier causes the value to be treated as a single word (possibly containing embedded whitespace). .Pp As for the .Cm \&:S modifier, the .Ar pattern and .Ar replacement are subjected to variable expansion before being parsed as regular expressions. .It Cm \&:T Replaces each word with its last path component (basename). .It Cm \&:u Removes adjacent duplicate words (like .Xr uniq 1 ) . .Sm off .It Cm \&:\&?\| Ar true_string\| Cm \&: Ar false_string .Sm on If the variable name (not its value), when parsed as a .Cm .if conditional expression, evaluates to true, return as its value the .Ar true_string , otherwise return the .Ar false_string . Since the variable name is used as the expression, \&:\&? must be the first modifier after the variable name .No itself Ns \^\(em\^ Ns which, of course, usually contains variable expansions. A common error is trying to use expressions like .Dl ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS). To determine if any words match .Dq 42 , you need to use something like: .Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} . .It Cm :\| Ns Ar old_string\| Ns Cm = Ns Ar new_string This is the .At V style substitution. It can only be the last modifier specified, as a .Ql \&: in either .Ar old_string or .Ar new_string is treated as a regular character, not as the end of the modifier. .Pp If .Ar old_string does not contain the pattern matching character .Ql % , and the word ends with .Ar old_string or equals it, that suffix is replaced with .Ar new_string . .Pp Otherwise, the first .Ql % in .Ar old_string matches a possibly empty substring of arbitrary characters, and if the whole pattern is found in the word, the matching part is replaced with .Ar new_string , and the first occurrence of .Ql % in .Ar new_string (if any) is replaced with the substring matched by the .Ql % . .Pp Both .Ar old_string and .Ar new_string may contain nested expressions. To prevent a dollar sign from starting a nested expression, escape it with a backslash. .Sm off .It Cm \&:@ Ar varname\| Cm @ Ar string\| Cm @ .Sm on This is the loop expansion mechanism from the OSF Development Environment (ODE) make. Unlike .Cm \&.for loops, expansion occurs at the time of reference. For each word in the value, assign the word to the variable named .Ar varname and evaluate .Ar string . The ODE convention is that .Ar varname should start and end with a period, for example: .Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} .Pp However, a single-letter variable is often more readable: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Cm \&:_ Ns Oo Cm = Ns Ar var Oc Saves the current variable value in .Ql $_ or the named .Ar var for later reference. Example usage: .Bd -literal -offset indent M_cmpv.units = 1 1000 1000000 M_cmpv = S,., ,g:_:range:@i@+ $${_:[-$$i]} \&\\ \\* $${M_cmpv.units:[$$i]}@:S,^,expr 0 ,1:sh .Dv .if ${VERSION:${M_cmpv}} < ${3.1.12:L:${M_cmpv}} .Ed Here .Ql $_ is used to save the result of the .Ql :S modifier which is later referenced using the index values from .Ql :range . .It Cm \&:U\| Ns Ar newval If the variable is undefined, .Ar newval is the value. If the variable is defined, the existing value is returned. This is another ODE make feature. It is handy for setting per-target CFLAGS for instance: .Dl ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}} If a value is only required if the variable is undefined, use: .Dl ${VAR:D:Unewval} .It Cm \&:D\| Ns Ar newval If the variable is defined, .Ar newval is the value. .It Cm \&:L The name of the variable is the value. .It Cm \&:P The path of the node which has the same name as the variable is the value. If no such node exists or its path is null, the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the right-hand side of a dependency. .Sm off .It Cm \&:\&! Ar cmd\| Cm \&! .Sm on The output of running .Ar cmd is the value. .It Cm \&:sh The value is run as a command, and the output becomes the new value. .It Cm \&::= Ns Ar str The variable is assigned the value .Ar str after substitution. This modifier and its variations are useful in obscure situations such as wanting to set a variable at a point where a target's shell commands are being parsed. These assignment modifiers always expand to nothing. .Pp The .Sq Cm \&:: helps avoid false matches with the .At V style .Ql \&:= modifier and since substitution always occurs, the .Ql \&::= form is vaguely appropriate. .It Cm \&::?= Ns Ar str As for .Cm \&::= but only if the variable does not already have a value. .It Cm \&::+= Ns Ar str Append .Ar str to the variable. .It Cm \&::!= Ns Ar cmd Assign the output of .Ar cmd to the variable. .It Cm \&:\&[ Ns Ar range Ns Cm \&] Selects one or more words from the value, or performs other operations related to the way in which the value is split into words. .Pp An empty value, or a value that consists entirely of white-space, is treated as a single word. For the purposes of the .Sq Cm \&:[] modifier, the words are indexed both forwards using positive integers (where index 1 represents the first word), and backwards using negative integers (where index \-1 represents the last word). .Pp The .Ar range is subjected to variable expansion, and the expanded result is then interpreted as follows: .Bl -tag -width index .\" :[n] .It Ar index Selects a single word from the value. .\" :[start..end] .It Ar start Ns Cm \&.. Ns Ar end Selects all words from .Ar start to .Ar end , inclusive. For example, .Sq Cm \&:[2..-1] selects all words from the second word to the last word. If .Ar start is greater than .Ar end , the words are output in reverse order. For example, .Sq Cm \&:[-1..1] selects all the words from last to first. If the list is already ordered, this effectively reverses the list, but it is more efficient to use .Sq Cm \&:Or instead of .Sq Cm \&:O:[-1..1] . .\" :[*] .It Cm \&* Causes subsequent modifiers to treat the value as a single word (possibly containing embedded whitespace). Analogous to the effect of .Li \&$* in Bourne shell. .\" :[0] .It 0 Means the same as .Sq Cm \&:[*] . .\" :[*] .It Cm \&@ Causes subsequent modifiers to treat the value as a sequence of words delimited by whitespace. Analogous to the effect of .Li \&$@ in Bourne shell. .\" :[#] .It Cm \&# Returns the number of words in the value. .El \" :[range] .El .Sh DIRECTIVES .Nm offers directives for including makefiles, conditionals and for loops. All these directives are identified by a line beginning with a single dot .Pq Ql \&. character, followed by the keyword of the directive, such as .Cm include or .Cm if . .Ss File inclusion Files are included with either .Cm \&.include \&< Ns Ar file Ns Cm \&> or .Cm \&.include \&\*q Ns Ar file Ns Cm \&\*q . Variables between the angle brackets or double quotes are expanded to form the file name. If angle brackets are used, the included makefile is expected to be in the system makefile directory. If double quotes are used, the including makefile's directory and any directories specified using the .Fl I option are searched before the system makefile directory. .Pp For compatibility with other make variants, .Sq Cm include Ar file No ... (without leading dot) is also accepted. .Pp If the include statement is written as .Cm .-include or as .Cm .sinclude , errors locating and/or opening include files are ignored. .Pp If the include statement is written as .Cm .dinclude , not only are errors locating and/or opening include files ignored, but stale dependencies within the included file are ignored just like in .Va .MAKE.DEPENDFILE . .Ss Exporting variables The directives for exporting and unexporting variables are: .Bl -tag -width Ds .It Ic .export Ar variable No ... Export the specified global variable. If no variable list is provided, all globals are exported except for internal variables (those that start with .Ql \&. ) . This is not affected by the .Fl X flag, so should be used with caution. For compatibility with other make programs, .Cm export Ar variable\| Ns Cm \&= Ns Ar value (without leading dot) is also accepted. .Pp Appending a variable name to .Va .MAKE.EXPORTED is equivalent to exporting a variable. .It Ic .export-env Ar variable No ... The same as .Ql .export , except that the variable is not appended to .Va .MAKE.EXPORTED . This allows exporting a value to the environment which is different from that used by .Nm internally. .It Ic .export-literal Ar variable No ... The same as .Ql .export-env , except that variables in the value are not expanded. .It Ic .unexport Ar variable No ... The opposite of .Ql .export . The specified global .Ar variable is removed from .Va .MAKE.EXPORTED . If no variable list is provided, all globals are unexported, and .Va .MAKE.EXPORTED deleted. .It Ic .unexport-env Unexport all globals previously exported and clear the environment inherited from the parent. This operation causes a memory leak of the original environment, so should be used sparingly. Testing for .Va .MAKE.LEVEL being 0 would make sense. Also note that any variables which originated in the parent environment should be explicitly preserved if desired. For example: .Bd -literal -offset indent .Li .if ${.MAKE.LEVEL} == 0 PATH := ${PATH} .Li .unexport-env .Li .export PATH .Li .endif .Pp .Ed Would result in an environment containing only .Sq Ev PATH , which is the minimal useful environment. .\" TODO: Check the below sentence, environment variables don't start with '.'. Actually .Sq Va .MAKE.LEVEL is also pushed into the new environment. .El .Ss Messages The directives for printing messages to the output are: .Bl -tag -width Ds .It Ic .info Ar message The message is printed along with the name of the makefile and line number. .It Ic .warning Ar message The message prefixed by .Sq Li warning: is printed along with the name of the makefile and line number. .It Ic .error Ar message The message is printed along with the name of the makefile and line number, .Nm exits immediately. .El .Ss Conditionals The directives for conditionals are: .ds maybenot Oo Ic \&! Oc Ns .Bl -tag .It Ic .if \*[maybenot] Ar expression Op Ar operator expression No ... Test the value of an expression. .It Ic .ifdef \*[maybenot] Ar variable Op Ar operator variable No ... Test whether a variable is defined. .It Ic .ifndef \*[maybenot] Ar variable Op Ar operator variable No ... Test whether a variable is not defined. .It Ic .ifmake \*[maybenot] Ar target Op Ar operator target No ... Test the target being requested. .It Ic .ifnmake \*[maybenot] Ar target Op Ar operator target No ... Test the target being requested. .It Ic .else Reverse the sense of the last conditional. .It Ic .elif \*[maybenot] Ar expression Op Ar operator expression No ... A combination of .Sq Ic .else followed by .Sq Ic .if . .It Ic .elifdef \*[maybenot] Ar variable Op Ar operator variable No ... A combination of .Sq Ic .else followed by .Sq Ic .ifdef . .It Ic .elifndef \*[maybenot] Ar variable Op Ar operator variable No ... A combination of .Sq Ic .else followed by .Sq Ic .ifndef . .It Ic .elifmake \*[maybenot] Ar target Op Ar operator target No ... A combination of .Sq Ic .else followed by .Sq Ic .ifmake . .It Ic .elifnmake \*[maybenot] Ar target Op Ar operator target No ... A combination of .Sq Ic .else followed by .Sq Ic .ifnmake . .It Ic .endif End the body of the conditional. .El .Pp The .Ar operator may be any one of the following: .Bl -tag .It Ic \&|\&| Logical OR. .It Ic \&&& Logical AND; of higher precedence than .Sq Ic \&|\&| . .El .Pp .Nm only evaluates a conditional as far as is necessary to determine its value. Parentheses can be used to override the operator precedence. The boolean operator .Sq Ic \&! -may be used to logically negate an entire conditional. +may be used to logically negate an expression, typically a function call. It is of higher precedence than .Sq Ic \&&& . .Pp The value of .Ar expression may be any of the following function call expressions: .Bl -tag .Sm off .It Ic defined Li \&( Ar varname Li \&) .Sm on Evaluates to true if the variable .Ar varname has been defined. .Sm off .It Ic make Li \&( Ar target Li \&) .Sm on Evaluates to true if the target was specified as part of .Nm Ns 's command line or was declared the default target (either implicitly or explicitly, see .Va .MAIN ) before the line containing the conditional. .Sm off .It Ic empty Li \&( Ar varname Oo Li : Ar modifiers Oc Li \&) .Sm on Evaluates to true if the expansion of the variable, after applying the modifiers, results in an empty string. .Sm off .It Ic exists Li \&( Ar pathname Li \&) .Sm on Evaluates to true if the given pathname exists. If relative, the pathname is searched for on the system search path (see .Va .PATH ) . .Sm off .It Ic target Li \&( Ar target Li \&) .Sm on Evaluates to true if the target has been defined. .Sm off .It Ic commands Li \&( Ar target Li \&) .Sm on Evaluates to true if the target has been defined and has commands associated with it. .El .Pp .Ar Expression may also be an arithmetic or string comparison. Variable expansion is performed on both sides of the comparison. If both sides are numeric and neither is enclosed in quotes, the comparison is done numerically, otherwise lexicographically. -A string is interpreted as hexadecimal integer if it is preceded by +A string is interpreted as a hexadecimal integer if it is preceded by .Li 0x , -otherwise it is a decimal floating-point number; +otherwise it is interpreted as a decimal floating-point number; octal numbers are not supported. .Pp All comparisons may use the operators .Sq Ic \&== and .Sq Ic \&!= . Numeric comparisons may also use the operators .Sq Ic \&< , .Sq Ic \&<= , .Sq Ic \&> and .Sq Ic \&>= . .Pp If the comparison has neither a comparison operator nor a right side, the expression evaluates to true if it is nonempty and its numeric value (if any) is not zero. .Pp When .Nm is evaluating one of these conditional expressions, and it encounters -a (whitespace separated) word it doesn't recognize, either the +a (whitespace-separated) word it doesn't recognize, either the .Dq make or .Dq defined function is applied to it, depending on the form of the conditional. If the form is .Sq Ic .ifdef , .Sq Ic .ifndef or .Sq Ic .if , the .Dq defined function is applied. Similarly, if the form is .Sq Ic .ifmake or .Sq Ic .ifnmake , the .Dq make function is applied. .Pp If the conditional evaluates to true, parsing of the makefile continues as before. -If it evaluates to false, the following lines are skipped. -In both cases, this continues until the corresponding +If it evaluates to false, the following lines until the corresponding +.Sq Ic .elif +variant, .Sq Ic .else or .Sq Ic .endif -is found. +are skipped. .Ss For loops For loops are typically used to apply a set of rules to a list of files. The syntax of a for loop is: .Pp .Bl -tag -compact -width Ds .It Ic \&.for Ar variable Oo Ar variable No ... Oc Ic in Ar expression .It Aq Ar make-lines .It Ic \&.endfor .El .Pp The .Ar expression is expanded and then split into words. On each iteration of the loop, one word is taken and assigned to each .Ar variable , in order, and these .Ar variables are substituted into the .Ar make-lines inside the body of the for loop. The number of words must come out even; that is, if there are three iteration variables, the number of words provided must be a multiple of three. .Pp If .Sq Ic .break is encountered within a .Cm \&.for loop, it causes early termination of the loop, otherwise a parse error. .\" TODO: Describe limitations with defined/empty. .Ss Other directives .Bl -tag -width Ds .It Ic .undef Ar variable No ... Un-define the specified global variables. Only global variables can be un-defined. .El .Sh COMMENTS Comments begin with a hash .Pq Ql \&# character, anywhere but in a shell command line, and continue to the end of an unescaped new line. .Sh SPECIAL SOURCES (ATTRIBUTES) .Bl -tag -width .IGNOREx .It Ic .EXEC Target is never out of date, but always execute commands anyway. .It Ic .IGNORE Ignore any errors from the commands associated with this target, exactly as if they all were preceded by a dash .Pq Ql \- . .\" .It Ic .INVISIBLE .\" XXX .\" .It Ic .JOIN .\" XXX .It Ic .MADE Mark all sources of this target as being up to date. .It Ic .MAKE Execute the commands associated with this target even if the .Fl n or .Fl t options were specified. Normally used to mark recursive .Nm Ns s . .It Ic .META Create a meta file for the target, even if it is flagged as .Ic .PHONY , .Ic .MAKE , or .Ic .SPECIAL . Usage in conjunction with .Ic .MAKE is the most likely case. In .Dq meta mode, the target is out-of-date if the meta file is missing. .It Ic .NOMETA Do not create a meta file for the target. Meta files are also not created for .Ic .PHONY , .Ic .MAKE , or .Ic .SPECIAL targets. .It Ic .NOMETA_CMP Ignore differences in commands when deciding if target is out of date. This is useful if the command contains a value which always changes. If the number of commands change, though, the target is still considered out of date. The same effect applies to any command line that uses the variable .Va .OODATE , which can be used for that purpose even when not otherwise needed or desired: .Bd -literal -offset indent skip-compare-for-some: @echo this is compared @echo this is not ${.OODATE:M.NOMETA_CMP} @echo this is also compared .Ed The .Cm \&:M pattern suppresses any expansion of the unwanted variable. .It Ic .NOPATH Do not search for the target in the directories specified by .Va .PATH . .It Ic .NOTMAIN Normally .Nm selects the first target it encounters as the default target to be built if no target was specified. This source prevents this target from being selected. .It Ic .OPTIONAL If a target is marked with this attribute and .Nm can't figure out how to create it, it ignores this fact and assumes the file isn't needed or already exists. .It Ic .PHONY The target does not correspond to an actual file; it is always considered to be out of date, and is not created with the .Fl t option. Suffix-transformation rules are not applied to .Ic .PHONY targets. .It Ic .PRECIOUS When .Nm is interrupted, it normally removes any partially made targets. This source prevents the target from being removed. .It Ic .RECURSIVE Synonym for .Ic .MAKE . .It Ic .SILENT Do not echo any of the commands associated with this target, exactly as if they all were preceded by an at sign .Pq Ql @ . .It Ic .USE Turn the target into .Nm Ns 's version of a macro. When the target is used as a source for another target, the other target acquires the commands, sources, and attributes (except for .Ic .USE ) of the source. If the target already has commands, the .Ic .USE target's commands are appended to them. .It Ic .USEBEFORE Like .Ic .USE , but instead of appending, prepend the .Ic .USEBEFORE target commands to the target. .It Ic .WAIT If .Ic .WAIT appears in a dependency line, the sources that precede it are made before the sources that succeed it in the line. Since the dependents of files are not made until the file itself could be made, this also stops the dependents being built unless they are needed for another branch of the dependency tree. So given: .Bd -literal x: a .WAIT b echo x a: echo a b: b1 echo b b1: echo b1 .Ed the output is always .Ql a , .Ql b1 , .Ql b , .Ql x . .Pp The ordering imposed by .Ic .WAIT is only relevant for parallel makes. .El .Sh SPECIAL TARGETS Special targets may not be included with other targets, i.e. they must be the only target specified. .Bl -tag -width .BEGINx .It Ic .BEGIN Any command lines attached to this target are executed before anything else is done. .It Ic .DEFAULT This is sort of a .Ic .USE rule for any target (that was used only as a source) that .Nm can't figure out any other way to create. Only the shell script is used. The .Va .IMPSRC variable of a target that inherits .Ic .DEFAULT Ns 's commands is set to the target's own name. .It Ic .DELETE_ON_ERROR If this target is present in the makefile, it globally causes make to delete targets whose commands fail. (By default, only targets whose commands are interrupted during execution are deleted. This is the historical behavior.) This setting can be used to help prevent half-finished or malformed targets from being left around and corrupting future rebuilds. .It Ic .END Any command lines attached to this target are executed after everything else is done successfully. .It Ic .ERROR Any command lines attached to this target are executed when another target fails. The .Va .ERROR_TARGET variable is set to the target that failed. See also .Va MAKE_PRINT_VAR_ON_ERROR . .It Ic .IGNORE Mark each of the sources with the .Ic .IGNORE attribute. If no sources are specified, this is the equivalent of specifying the .Fl i option. .It Ic .INTERRUPT If .Nm is interrupted, the commands for this target are executed. .It Ic .MAIN If no target is specified when .Nm is invoked, this target is built. .It Ic .MAKEFLAGS This target provides a way to specify flags for .Nm at the time when the makefiles are read. The flags are as if typed to the shell, though the .Fl f option has no effect. .\" XXX: NOT YET!!!! .\" .It Ic .NOTPARALLEL .\" The named targets are executed in non parallel mode. .\" If no targets are .\" specified, all targets are executed in non parallel mode. .It Ic .NOPATH Apply the .Ic .NOPATH attribute to any specified sources. .It Ic .NOTPARALLEL Disable parallel mode. .It Ic .NO_PARALLEL Synonym for .Ic .NOTPARALLEL , for compatibility with other pmake variants. .It Ic .NOREADONLY clear the read-only attribute from the global variables specified as sources. .It Ic .OBJDIR The source is a new value for .Sq Va .OBJDIR . If it exists, .Nm changes the current working directory to it and updates the value of .Sq Va .OBJDIR . .It Ic .ORDER In parallel mode, the named targets are made in sequence. This ordering does not add targets to the list of targets to be made. .Pp Since the dependents of a target do not get built until the target itself could be built, unless .Ql a is built by another part of the dependency graph, the following is a dependency loop: .Bd -literal \&.ORDER: b a b: a .Ed .Pp .\" XXX: NOT YET!!!! .\" .It Ic .PARALLEL .\" The named targets are executed in parallel mode. .\" If no targets are .\" specified, all targets are executed in parallel mode. .It Ic .PATH The sources are directories which are to be searched for files not found in the current directory. If no sources are specified, any previously specified directories are removed from the search path. If the source is the special .Ic .DOTLAST target, the current working directory is searched last. .It Ic .PATH. Ns Ar suffix Like .Ic .PATH but applies only to files with a particular suffix. The suffix must have been previously declared with .Ic .SUFFIXES . .It Ic .PHONY Apply the .Ic .PHONY attribute to any specified sources. .It Ic .POSIX If this is the first non-comment line in the main makefile, the variable .Va %POSIX is set to the value .Ql 1003.2 and the makefile .Ql is included if it exists, to provide POSIX-compatible default rules. If .Nm is run with the .Fl r flag, only .Ql posix.mk contributes to the default rules. .It Ic .PRECIOUS Apply the .Ic .PRECIOUS attribute to any specified sources. If no sources are specified, the .Ic .PRECIOUS attribute is applied to every target in the file. .It Ic .READONLY set the read-only attribute on the global variables specified as sources. .It Ic .SHELL Sets the shell that .Nm uses to execute commands in jobs mode. The sources are a set of .Ar field\| Ns Cm \&= Ns Ar value pairs. .Bl -tag -width ".Li hasErrCtls" .It Li name This is the minimal specification, used to select one of the built-in shell specs; .Li sh , .Li ksh , and .Li csh . .It Li path Specifies the absolute path to the shell. .It Li hasErrCtl Indicates whether the shell supports exit on error. .It Li check The command to turn on error checking. .It Li ignore The command to disable error checking. .It Li echo The command to turn on echoing of commands executed. .It Li quiet The command to turn off echoing of commands executed. .It Li filter The output to filter after issuing the .Li quiet command. It is typically identical to .Li quiet . .It Li errFlag The flag to pass the shell to enable error checking. .It Li echoFlag The flag to pass the shell to enable command echoing. .It Li newline The string literal to pass the shell that results in a single newline character when used outside of any quoting characters. .El Example: .Bd -literal \&.SHELL: name=ksh path=/bin/ksh hasErrCtl=true \e check="set \-e" ignore="set +e" \e echo="set \-v" quiet="set +v" filter="set +v" \e echoFlag=v errFlag=e newline="'\en'" .Ed .It Ic .SILENT Apply the .Ic .SILENT attribute to any specified sources. If no sources are specified, the .Ic .SILENT attribute is applied to every command in the file. .It Ic .STALE This target gets run when a dependency file contains stale entries, having .Va .ALLSRC set to the name of that dependency file. .It Ic .SUFFIXES Each source specifies a suffix to .Nm . If no sources are specified, any previously specified suffixes are deleted. It allows the creation of suffix-transformation rules. .Pp Example: .Bd -literal \&.SUFFIXES: .c .o \&.c.o: cc \-o ${.TARGET} \-c ${.IMPSRC} .Ed .It Ic .SYSPATH The sources are directories which are to be added to the system include path which .Nm searches for makefiles. If no sources are specified, any previously specified directories are removed from the system include path. .El .Sh ENVIRONMENT .Nm uses the following environment variables, if they exist: .Ev MACHINE , .Ev MACHINE_ARCH , .Ev MAKE , .Ev MAKEFLAGS , .Ev MAKEOBJDIR , .Ev MAKEOBJDIRPREFIX , .Ev MAKESYSPATH , .Ev PWD , and .Ev TMPDIR . .Pp .Ev MAKEOBJDIRPREFIX and .Ev MAKEOBJDIR may only be set in the environment or on the command line to .Nm and not as makefile variables; see the description of .Sq Va .OBJDIR for more details. .Sh FILES .Bl -tag -width /usr/share/mk -compact .It .depend list of dependencies .It makefile first default makefile if no makefile is specified on the command line .It Makefile second default makefile if no makefile is specified on the command line .It sys.mk system makefile .It /usr/share/mk system makefile directory .El .Sh COMPATIBILITY The basic make syntax is compatible between different make variants; however the special variables, variable modifiers and conditionals are not. .Ss Older versions An incomplete list of changes in older versions of .Nm : .Pp The way that .for loop variables are substituted changed after .Nx 5.0 so that they still appear to be variable expansions. In particular this stops them being treated as syntax, and removes some obscure problems using them in .if statements. .Pp The way that parallel makes are scheduled changed in .Nx 4.0 so that .ORDER and .WAIT apply recursively to the dependent nodes. The algorithms used may change again in the future. .Ss Other make dialects Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not support most of the features of .Nm as described in this manual. Most notably: .Bl -bullet -offset indent .It The .Ic .WAIT and .Ic .ORDER declarations and most functionality pertaining to parallelization. (GNU make supports parallelization but lacks the features needed to control it effectively.) .It Directives, including for loops and conditionals and most of the forms of include files. (GNU make has its own incompatible and less powerful syntax for conditionals.) .\" The "less powerful" above means that GNU make does not have the .\" make(target), target(target) and commands(target) functions. .It All built-in variables that begin with a dot. .It Most of the special sources and targets that begin with a dot, with the notable exception of .Ic .PHONY , .Ic .PRECIOUS , and .Ic .SUFFIXES . .It Variable modifiers, except for the .Ql :old=new string substitution, which does not portably support globbing with .Ql % and historically only works on declared suffixes. .It The .Ic $> variable even in its short form; most makes support this functionality but its name varies. .El .Pp Some features are somewhat more portable, such as assignment with .Ic += , .Ic ?= , and .Ic != . The .Va .PATH functionality is based on an older feature .Ic VPATH found in GNU make and many versions of SVR4 make; however, historically its behavior is too ill-defined (and too buggy) to rely upon. .Pp The .Ic $@ and .Ic $< variables are more or less universally portable, as is the .Ic $(MAKE) variable. Basic use of suffix rules (for files only in the current directory, not trying to chain transformations together, etc.) is also reasonably portable. .Sh SEE ALSO .Xr mkdep 1 , .Xr style.Makefile 5 .Sh HISTORY A .Nm command appeared in .At v7 . This .Nm implementation is based on Adam de Boor's pmake program, which was written for Sprite at Berkeley. It was designed to be a parallel distributed make running jobs on different machines using a daemon called .Dq customs . .Pp Historically the target/dependency .Ic FRC has been used to FoRCe rebuilding (since the target/dependency does not exist ... unless someone creates an .Pa FRC file). .Sh BUGS The .Nm syntax is difficult to parse. For instance, finding the end of a variable's use should involve scanning each of the modifiers, using the correct terminator for each field. In many places .Nm just counts {} and () in order to find the end of a variable expansion. .Pp There is no way of escaping a space character in a filename. .Pp In jobs mode, when a target fails; .Nm will put an error token into the job token pool. This will cause all other instances of .Nm using that token pool to abort the build and exit with error code 6. Sometimes the attempt to suppress a cascade of unnecessary errors, can result in a seemingly unexplained .Ql *** Error code 6 diff --git a/contrib/bmake/make.h b/contrib/bmake/make.h index 50e590eb4c93..dab619c95b80 100644 --- a/contrib/bmake/make.h +++ b/contrib/bmake/make.h @@ -1,1242 +1,1249 @@ -/* $NetBSD: make.h,v 1.323 2023/06/20 09:25:33 rillig Exp $ */ +/* $NetBSD: make.h,v 1.325 2023/09/10 11:52:29 rillig Exp $ */ /* * Copyright (c) 1988, 1989, 1990, 1993 * The Regents of the University of California.

DEP_TARGET_SPEC is just ${DEP_MACHINE} * meta.sys.mk: ensure DEP_* for TARGET_SPEC_VARS are set at level > 0 since these are often refered to in Makefile.depend* 2023-04-26 Simon J Gerraty * jobs.mk: report ${.TARGET} ${JOB_ARGS} ${JOB_LOG} and anything in ${JOB_LOG_START} * jobs.mk: look for newlog.sh in ${.SYSPATH:U${.PARSEDIR}} or a scripts subdir before searching $PATH. * FILES: include newlog.sh for jobs.mk 2023-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20230420 * lib.mk: include LDFLAGS and LDADD when linking shared libs * gendirdeps.mk: document setting GENDIRDEPS_FILTER_VARS etc via local.meta.sys.mk rather than local.gendirdeps.mk so DEP_* variables can be set at level 1+ to avoid syntax errors when used in conditionals in manually maintained Makefile.depend files. * dirdeps.mk: ensure M_dep_qual_fixes is applied to all _machines 2023-04-18 Simon J Gerraty * dirdeps.mk: check we were not included by Makefile.depend.options as the result is bad. 2023-04-14 Simon J Gerraty * install-mk (MK_VERSION): 20230414 * meta.sys.mk: since we have :range we can put the logic for processing TARGET_SPEC from env here. * dirdeps.mk: reset DIRDEPS and DEP_RELDIR before including local.dirdeps-missing.mk, also improve debug output. * dirdeps.mk: to allow make -f dirdeps.mk include.$TARGET_SPEC we need to use :M*[/.]* same as for when actually setting DIRDEPS from the targets on command line. 2023-04-12 Simon J Gerraty * Add jobs.mk 2023-03-21 Simon J Gerraty * install-mk (MK_VERSION): 20230321 * meta.stage.mk: allow STAGE_SHLIB_LINKS_FILTER to filter STAGE_LIBS for SHLIB_LINKS. * autoconf.mk: add .WAIT after config.status 2023-02-17 Simon J Gerraty * sys.vars.mk: add M_Index to report the index of a word in a list. 2023-02-15 Simon J Gerraty * install-mk (MK_VERSION): 20230215 * warnings.mk: allow better control of -Werror allow -Wno-error or similar to be added if WARNINGS_SET < WERROR_SET account for COMPILER_TYPE 2023-01-29 Simon J Gerraty * autoconf.mk: hook config.status to beforebuild. * whats.mk: what*.c is NOTMAIN 2023-01-27 Simon J Gerraty * install-mk (MK_VERSION): 20230127 control umask so directories are created with suitable mode. 2023-01-20 Simon J Gerraty * install-mk (MK_VERSION): 20230120 * sys.vars.mk: add M_On and M_Onr also cleanup to be more consistent wrt testing MAKE_VERSION 2023-01-12 Simon J Gerraty * install-mk (MK_VERSION): 20230112 * meta2deps.{py,sh}: assert if filemon data is truncated we should see the '# Bye bye' record - assert if we do not. 2022-09-09 Simon J Gerraty * install-mk (MK_VERSION): 20220909 * sys/Linux.mk set EGREP to grep -E to avoid deprecation warnings 2022-09-06 Simon J Gerraty * dirdeps-options.mk: explain the need to use ${DEP_${TARGET_SPEC_VAR}:U${TARGET_SPEC_VAR}} when refering to ${TARGET_SPEC_VAR} 2022-09-03 Simon J Gerraty * install-mk (MK_VERSION): 20220903 * M_cmpv handle more than 3 dots and clear leading 0's 2022-07-20 Simon J Gerraty * install-mk (MK_VERSION): 20220720 * prog.mk: handle PROG_CXX for more than just NetBSD 2022-06-20 Simon J Gerraty * install-mk (MK_VERSION): 20220620 * yacc.mk: when we have *.y in SRCS used explicit rules and .ORDER rather than just suffix rules 2022-04-23 Simon J Gerraty * install-mk (MK_VERSION): 20220422 * gendirdeps.mk: If LOCAL_DEPENDS_GUARD is set to "no" do not capture any local depends in Makefile.depend 2022-03-25 Simon J Gerraty * install-mk (MK_VERSION): 20220323 * posix.mk: default rules for .POSIX: 2022-03-17 Simon J Gerraty * sys/*.mk: remove l from ARFLAGS 2022-03-14 Simon J Gerraty * install-mk (MK_VERSION): 20220314 * dirdeps-options.mk: allow options to be per RELDIR try DIRDEPS_OPTIONS_QUALIFIER_LIST first prefixed with ${DEP_RELDIR}. 2022-02-14 Simon J Gerraty * install-mk (MK_VERSION): 20220214 * cc-wrap.mk: fix :@ modifier 2022-02-06 Simon J Gerraty * install-mk (MK_VERSION): 20220206 * cc-wrap.mk: docuement how CCACHE etc might be set for maximum flexibility 2022-02-05 Simon J Gerraty * sys.vars.mk: use JOT_CMD (jot or seq) if available for M_JOT 2022-02-04 Simon J Gerraty * install-mk (MK_VERSION): 20220204 * host-target.mk: use .MAKE.OS if available 2022-02-02 Simon J Gerraty * install-mk (MK_VERSION): 20220202 * cc-wrap.mk: allow other entries in CC_WRAP_FILTER We add our filter on extensions last, so prior filters can apply to the whole value of .IMPSRC 2022-02-01 Simon J Gerraty * cc-wrap.mk: take advantage of target local variables to wrap compilers like CC CXX with wrappers like ccache distcc etc 2022-01-28 Simon J Gerraty * meta2deps: we do not expect any trace data for setid apps 2022-01-26 Simon J Gerraty * dirdeps.mk: ensure TARGET_SPEC and TARGET_SPEC_VARS are passed to sub-make using DIRDEPS_CACHE 2022-01-07 Simon J Gerraty * dirdeps.mk: use _cache_script to minimize the number of shells forked when generating dirdeps.cache 2022-01-02 Simon J Gerraty * install-mk (MK_VERSION): 20220101 * dirdeps.mk: initialize DEP_* and _debug_reldir earlier. If initial DIRDEPS are from command line, create the target _dirdeps_cmdline as an indication. 2022-01-01 Simon J Gerraty * init.mk (_SKIP_BUILD): when doing DIRDEPS_BUILD at top-level only some targets are allowed at level 0, for leaf makefiles only the default (all) target is restricted 2021-12-28 Simon J Gerraty * install-mk (MK_VERSION): 20211228 * meta2deps.py: filemon on Linux is not as reliable as we might like, we do not want to update DIRDEPS if filemon output is incomplete. Track pids that we 'E'xec and make sure we see an e'X'it for each one. Throw an error if we are missing any 'X' records. 2021-12-12 Simon J Gerraty * sys.mk: simplify; include meta.sys.mk if MK_META_MODE is yes. * meta.sys.mk: do not check for /dev/filemon if .MAKE.PATH_FILEMON is something else. * meta.autodep.mk: we can now reference ${.SUFFIXES} * meta2deps.py: derive a list of dirdep extensions from TARGET_SPEC to trim from dirdeps. * dirdeps.mk: flip the computation of qualified vs unqualified dirdeps - it is much simpler to check for unqualified first. 2021-12-11 Simon J Gerraty * install-mk (MK_VERSION): 20211212 * auto.dep.mk: rearrange so that the trivial implementation for recent bmake is more obvious. 2021-12-07 Simon J Gerraty * install-mk (MK_VERSION): 20211207 * Ensure guard targets are .NOTMAIN * meta.sys.mk: check for nofilemon support when we skip level 0 * auto.dep.mk: make this usable in meta mode for platforms that cannot use meta.autodep.mk * meta2deps.py: avoid confusion if MACHINE and another TARGET_SPEC_VAR have same value. 2021-11-27 Simon J Gerraty * dirdeps.mk: when building dirdeps.cache, minimize the amount of data put into env, by stripping ${SRCTOP}/ from each entry. A long sandbox name can double the amount of memory consumed and in extreme cases cause failure. While we are at it, strip ${SRCTOP}/ from a lot of the debug output. 2021-11-11 Simon J Gerraty * install-mk (MK_VERSION): 20211111 * meta.stage.mk (LN_CP_SCRIPT): if staging to NFS cp -p can fail so fallback to cp if necessary. 2021-10-30 Simon J Gerraty * man.mk (CMT2DOC): use cmt2doc.py rather than the 30 year old cmt2doc.pl 2021-10-24 Simon J Gerraty * meta.stage.mk: stage_as_and_symlink use ${STAGE_LINK_AS_$f:U$f} as the symlink (rare) 2021-10-16 Simon J Gerraty * autoconf.mk: if AUTOCONF_GENERATED_MAKEFILE is set and has not been read, throw an error after running configure telling user to restart. 2021-10-13 Simon J Gerraty * install-mk (MK_VERSION): 20211011 * Add support for SCO_SV 2021-10-01 Simon J Gerraty * install-mk (MK_VERSION): 20211001 * man.mk: use MAN_SUFFIXES and CMT2DOC_SUFFIXES for more flexibility 2021-09-13 Simon J Gerraty * options.mk (describe-options): print options and their values and optional description 2021-09-11 Simon J Gerraty * install-mk (MK_VERSION): 20210911 * options.mk (show-options): print options and their values 2021-09-08 Simon J Gerraty * install-mk (MK_VERSION): 20210909 * lib.mk: apply patch from to fix shared libs on Linux 2021-08-08 Simon J Gerraty * install-mk (MK_VERSION): 20210808 * options.mk: issue warning for WITH_*=no 2021-06-16 Simon J Gerraty * install-mk (MK_VERSION): 20210616 * dirdeps.mk: when using .MAKE.DEPENDFILE_PREFERENCE to find depend files to read, anchor MACHINE at , or end of string to avoid prefix match. 2021-05-04 Simon J Gerraty * install-mk (MK_VERSION): 20210504 * dirdeps.mk: re-implement ALL_MACHINES support to better cater for local complexities, when ONLY_TARGET_SPEC_LIST is not set. local.dirdeps.mk can set DIRDEPS_ALL_MACHINES_FILTER and/or DIRDEPS_ALL_MACHINES_FILTER_XTRAS to filter the results we get from listing all existing Makefile.depend.* 2021-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20210420 * dirdeps.mk: revert previous - not always safe. 2021-03-20 Simon J Gerraty * install-mk (MK_VERSION): 20210321 * dirdeps.mk: when generating dirdeps.cache we only need to hook the initial DIRDEPS to the dirdeps target. That and any _build_xtra_dirs (like tests which should not be hooked directly to the dependency graph - to avoid cycles) 2021-01-30 Simon J Gerraty * install-mk (MK_VERSION): 20210130 * dirdeps.mk: expr 2 - 1 - 1 exits with a bad status we need to guard against this in DIRDEP_LOADAVG_REPORT. * dirdeps.mk: restore respect for TARGET_MACHINE 2021-01-06 Simon J Gerraty * install-mk (MK_VERSION): 20210101 * dirdeps.mk: first time we are read, just use TARGET_SPEC for _DEP_TARGET_SPEC 2020-12-22 Simon J Gerraty * sys.mk (MAKE_SHELL): use ${.SHELL:Ush} and use := when setting SHELL 2020-12-21 Simon J Gerraty * install-mk (MK_VERSION): 20201221 * dirdeps-options.mk: latest bmake allows only one arg to .undef 2020-12-11 Simon J Gerraty * dirdeps-targets.mk: allow for "." in DIRDEPS_TARGETS_DIRS so that any directory can be treated as a target. 2020-11-26 Simon J Gerraty * install-mk (MK_VERSION): 20201126 * own.mk: use .MAKE.{UID,GID} if available. * init.mk: suppress _SKIP_BUILD warning if doing -V 2020-11-20 Simon J Gerraty * install-mk (MK_VERSION): 20201120 * init.mk: rename LEVEL0_TARGETS to DIRDEPS_BUILD_LEVEL0_TARGETS * dirdeps-targets.mk: fix typo in comment 2020-11-06 Simon J Gerraty * install-mk (MK_VERSION): 20201106 * meta.autodep.mk: use OBJ_EXTENSIONS rather than hardcode sed args to tweak extensions for local deps. 2020-11-01 Simon J Gerraty * install-mk (MK_VERSION): 20201101 * dirdeps.mk: most leaf makefiles are not suitable for building dirdeps.cache so if RELDIR is not "." use dirdeps.mk 2020-10-28 Simon J Gerraty * install-mk (MK_VERSION): 20201028 * dirdeps.mk: if we don't have :range use equivalent of M_RANGE when building dirdeps.cache for leaf directory use -f dirdeps.mk * sys.vars.mk: add M_JOT and M_RANGE 2020-10-01 Simon J Gerraty * install-mk (MK_VERSION): 20201001 * meta2deps.{py,sh}: throw an error if we don't see filemon version 2020-09-09 Simon J Gerraty * install-mk (MK_VERSION): 20200909 * dirdeps-cache-update.mk: use cache_update_dirdep as guard target 2020-08-26 Simon J Gerraty * dirdeps.mk: ensure we cannot confuse a static cache for dynamic (even more rare that use of static cache is playing clever tricks with it) 2020-08-16 Simon J Gerraty * dirdeps-cache-update.mk: allow MK_STATIC_DIRDEPS_CACHE_UPDATE_IMMEDIATE to control when we actually update STATIC_DIRDEPS_CACHE. * stage-install.sh: create dest directory if needed before running install(1) 2020-08-10 Simon J Gerraty * dirdeps-targets.mk: include Makefile.dirdeps.options * dirdeps.mk: use _TARGETS if defined for DIRDEPS_CACHE 2020-08-09 Simon J Gerraty * dirdeps.mk: default BUILD_DIRDEPS_MAKEFILE to empty * dirdeps-cache-update.mk: building parallel cache update under the context of dirdeps-cached would be ideal, but is problematic, so it runs as a sibling. Use cache-built target to ensure we wait for it to complete if necessary. 2020-08-06 Simon J Gerraty * install-mk (MK_VERSION): 20200806 * dirdeps-options: allow TARGET_SPEC to affect option values. Use DIRDEPS_OPTIONS_QUALIFIER_LIST before using bare MK_* * dirdeps-targets.mk: check for MK_STATIC_DIRDEPS_CACHE defined before looking for STATIC_DIRDEPS_CACHE 2020-08-05 Simon J Gerraty * host-target.mk: Darwin use MACHINE for HOST_ARCH too * dirdeps-options.mk: improve debug output 2020-07-22 Simon J Gerraty * dirdeps.mk: set and export DYNAMIC_DIRDEPS_CACHE for use by dirdeps-cache-update.mk * dirdeps-targets.mk: set and export STATIC_DIRDEPS_CACHE for use by dirdeps-cache-update.mk even if we don't use it. * dirdeps-cache-update.mk: we only need worry about the background update case, with the above, the update from DIRDEPS_CACHE is simple. * meta2deps.py: R 1234 . is not interesting 2020-07-20 Simon J Gerraty * sys.mk: default MK_STATIC_DIRDEPS_CACHE from MK_DIRDEPS_CACHE * dirdeps-options.mk: do not :tu DIRDEPS_OPTIONS allows use of lower case for pseudo options. * dirdeps-cache-update.mk: magic to deal with STATIC_DIRDEPS_CACHE 2020-07-18 Simon J Gerraty * dirdeps-targets.mk: Look for Makefile.dirdeps.cache which allows us to have a static cache for expensive targets. Use -DWITHOUT_STATIC_DIRDEPS_CACHE -DWITH_DIRDEPS_CACHE to regenerate the dirdeps.cache it is a copy of. 2020-07-17 Simon J Gerraty * Get rid of BUILD_AT_LEVEL0, MK_DIRDEPS_BUILD makes more sense. 2020-07-16 Simon J Gerraty * dirdeps.mk (DIRDEP_LOADAVG_REPORT): make it easy to record load averages at intervals during build. 2020-07-15 Simon J Gerraty * install-mk (MK_VERSION): 20200715 * dirdeps.mk: tweak Checking line to make matching Finished lines for post-build analysis easier. * meta.autodep.mk: use !defined(WITHOUT_META_STATS) * progs.mk: avoid prog.mk outputting multiple Finished lines 2020-07-11 Simon J Gerraty * dirdeps.mk: further optimize dirdeps.cache generate a DIRDEPS.${.TARGET} list for other purposes and improve the layout. 2020-07-10 Simon J Gerraty * dirdeps.mk: optimize content of dirdeps.cache 2020-06-28 Simon J Gerraty * sys/*.mk: make it easier for local*sys.mk to customize by using ?= 2020-06-22 Simon J Gerraty * gendirdeps.mk (LOCAL_DEPENDS_GUARD): if we don't build at level 0 it is much safer to guard local depends with a simple check for .MAKE.LEVEL > 0 2020-06-10 Simon J Gerraty * install-mk (MK_VERSION): 20200610 * mkopt.sh: this needs posix shell so #!/bin/sh should be ok 2020-06-06 Simon J Gerraty * install-mk (MK_VERSION): 20200606 * dirdeps-targets.mk: allow for filtering of .TARGETS * meta2deps.py: fix bug in processing 'L'ink and 'M'ove entries - and we don't care about 'W'rite entries. Also ignore absolute paths that do not exist. 2020-05-25 Simon J Gerraty * install-mk (MK_VERSION): 20200525 * init.mk: expand and simplify handling of qualified vars like CPPFLAGS.${.TARGET:T} 2020-05-15 Simon J Gerraty * install-mk (MK_VERSION): 20200515 * dirdeps.mk: set _debug_* earlier and allow passing -d* flags to submake when building DIRDEPS_CACHE 2020-05-09 Simon J Gerraty * whats.mk: more easily extensible 2020-05-02 Simon J Gerraty * whats.mk: greatly simplify by adding what.c to SRCS 2020-05-01 Simon J Gerraty * whats.mk: for libs take care how we add to *OBJS * lib.mk: : works better with whats.mk 2020-04-25 Simon J Gerraty * install-mk (MK_VERSION): 20200420 * meta.stage.mk: it is not a STAGE_CONFLICT if some-target.dirdep contains the same ${RELDIR} and a prefix match for our ${TARGET_SPEC} 2020-04-16 Simon J Gerraty * install-mk (MK_VERSION): 20200416 * sys/*.mk: set MAKE_SHELL rather than SHELL so as not to interfere with user env. * sys.mk: default MAKE_SHELL to sh and SHELL to MAKE_SHELL * autodep.mk: use MAKE_SHELL. 2019-11-21 Simon J Gerraty * gendirdeps.mk: clear .SUFFIXES to avoid a lot of wasted effort, and unexport _meta_files when no longer needed as it consumes space we need for command line. 2019-11-11 Simon J Gerraty * dirdeps.mk _DIRDEP_USE: use DIRDEP_DIR and add DIRDEP_USE_PRELUDE at start - facilitates job distribution 2019-10-04 Simon J Gerraty * dirdeps-targets.mk: Use TARGET_SPEC_LAST_LIST defaults to ${${TARGET_SPEC_VARS:[-1]}_LIST} to match valid TARGET_SPEC qualified depend files. 2019-10-02 Simon J Gerraty * dirdeps-targets.mk: encapsulate logic for finding top-level targets to set initial DIRDEPS for DIRDEPS_BUILD 2019-09-27 Simon J Gerraty * install-mk (MK_VERSION): 20190911 * compiler.mk: set COMPILER_TYPE 2019-07-17 Simon J Gerraty * install-mk (MK_VERSION): 20190704 * sys/Darwin.mk: support for Objective-C and clang 2019-05-30 Simon J Gerraty * dirdeps.mk: avoid insanely long command line when generating cache 2019-05-23 Simon J Gerraty * install-mk (MK_VERSION): 20190505 * whats.mk: handle corner case SHLIB defined but not LIB 2018-09-19 Simon J Gerraty * install-mk (MK_VERSION): 20180919 * dirdeps-options.mk: .undef cannot handle var that expands to more than one var. 2018-07-08 Simon J Gerraty * meta.stage.mk: allow wildcards in STAGE_FILES.* etc. 2018-06-01 Simon J Gerraty * meta.autodep.mk: export META_FILES to avoid command line limit * gendirdeps.mk: if we have lots of .meta files put them in an @list 2018-05-28 Simon J Gerraty * dirdeps-options.mk: use local.dirdeps-options.mk not local.dirdeps-option.mk 2018-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20180420 * dirdeps.mk: include local.dirdeps-build.mk when .MAKE.LEVEL > 0 ie. we are building something. 2018-04-14 Simon J Gerraty * FILES: add dirdeps-options.mk to deal with optional DIRDEPS. 2018-04-05 Simon J Gerraty * install-mk (MK_VERSION): 20180405 * ldorder.mk: describe how to use LDORDER_EXTERN_BARRIER if needed. 2018-01-18 Simon J Gerraty * install-mk (MK_VERSION): 20180118 * ldorder.mk: let make compute correct link order 2017-12-12 Simon J Gerraty * install-mk (MK_VERSION): 20171212 * gendirdeps.mk: guard against bogus entries in GENDIRDEPS_FILTER 2017-11-14 Simon J.

Gerraty * meta2deps.py: take special care of '..' 2017-05-15 Simon J. Gerraty * install-mk (MK_VERSION): 20170515 * dirdeps.mk (DEP_EXPORT_VARS): on rare occasions it is useful/necessary for a Makefile.depend file to export some knobs. This is complicated when we are doing DIRDEPS_CACHE, so we will handle export of any variables listed in DEP_EXPORT_VARS. 2017-05-08 Simon J. Gerraty * install-mk (MK_VERSION): 20170505 * meta2deps.py: fix botched indenation. 2017-05-05 Simon J. Gerraty * sys/*.mk: Remove setting of MAKE it is unnecessary and in many cases wrong (basname rather than full path) * scripts.mk (SCRIPTSGROUPS): make this more like files.mk and inc.mk * init.mk: define realbuild to simplify logic in {lib,prog}.mk etc 2017-05-01 Simon J. Gerraty * install-mk (MK_VERSION): 20170501 * doc.mk: fix typo in DOC_INSTALL_OWN * inc.mk: handle INCGROUPS similar to freebsd * files.mk: add something for files too * add staging logic to lib.mk prog.mk etc. 2017-04-24 Simon J.

Gerraty * install-mk (MK_VERSION): 20170401 * meta2deps.py: add is_src so we can check if obj dependency is also a src dependency. 2017-03-26 Simon J. Gerraty * install-mk (MK_VERSION): 20170326 * meta.stage.mk: do nothing if NO_STAGING is defined. 2017-03-24 Simon J.

Gerraty * install-mk (MK_VERSION): 20161207 * meta.stage.mk: add stage_as_and_symlink for staging packages. We build foo.tgz stage_as foo-${VERSION}.tgz but want to be able to use foo.tgz to reference the latest staged version - so we make foo.tgz a symlink to it. Using a target to do both operations ensures we stay in sync. 2016-11-26 Simon J. Gerraty * install-mk (MK_VERSION): 20161126 * dirdeps.mk: set DIRDEPS_CACHE before we include local.dirdeps.mk so it can add dependencies. 2016-10-10 Simon J.

Before we read another Makefile.depend* set DEP_* vars from _DEP_TARGET_SPEC in case it uses any of them with := When bootstrapping, trim any ,* from extention of chosen _src Makefile.depend* to get the machine value we subst for. 2016-09-30 Simon J. Gerraty * dirdeps.mk: use TARGET_SPEC_VARS to qualify components added to DEP_SKIP_DIR and DEP_DIRDEPS_FILTER * sys.mk: extract some bits to sys.{debug,vars}.mk for easier re-use by others. 2016-09-23 Simon Gerraty * lib.mk: Use ${PICO} for extension for PIC objects. default to .pico (like NetBSD) safe on case insensitive filesystem. 2016-08-19 Simon J. Gerraty * meta.sys.mk (META_COOKIE_TOUCH): use ${.OBJDIR}/${.TARGET:T} as default 2016-08-15 Simon J. Gerraty * install-mk (MK_VERSION): 20160815 * dirdeps.mk (.MAKE.META.IGNORE_FILTER): set filter to only consider Makefile.depend* when checking if DIRDEPS_CACHE is up-to-date. 2016-08-13 Simon J. Gerraty * meta.sys.mk (.MAKE.META.IGNORE_PATHS): in meta mode we can ignore the mtime of makefiles 2016-08-02 Simon J. Gerraty * install-mk (MK_VERSION): 20160802 * lib.mk (libinstall): depends on beforinstall * prog.mk (proginstall): depends on beforinstall patch from Lauri Tirkkonen * dirdeps.mk (bootstrap): When bootstrapping; creat .MAKE.DEPENDFILE_DEFAULT and allow additional filtering via .MAKE.DEPENDFILE_BOOTSTRAP_SED * dirdeps.mk: move some comments to where they make sense. 2016-07-27 Simon J. Gerraty * dirdeps.mk (DIRDEPS_CACHE): no dirname. 2016-06-02 Simon J. Gerraty * install-mk (MK_VERSION): 20160602 * meta.autodep.mk: when passing META_FILES to gendirdeps.mk do not apply :T to META_XTRAS patch from Bryan Drewery at FreeBSD.org. 2016-05-30 Simon J. Gerraty * install-mk (MK_VERSION): 20160530 * meta.stage.mk: we assume ${CLEANFILES} gets .NOPATH make it so. 2016-05-12 Simon J. Gerraty * install-mk (MK_VERSION): 20160512 * dpadd.mk: always include local.dpadd.mk if it exists remove some things that better belong in local.dpadd.mk skip INCLUDES_* for staged libs unless SRC_* defined. * own.mk: add INCLUDEDIR 2016-04-18 Simon J. Gerraty * dirdeps.mk: when doing -f dirdeps.mk if target suppies no TARGET_MACHINE - :E will be empty or match part of path, use ${MACHINE} 2016-04-07 Simon J. Gerraty * meta.autodep.mk: issue a warning if UPDATE_DEPENDFILE=NO due to NO_FILEMON_COOKIE * dirdeps.mk: move the logic that allows for make -f dirdeps.mk some/dir.${TARGET_SPEC} inside the check for !target(_DIRDEP_USE) 2016-04-04 Simon J. Gerraty * Use <> when including local*.mk and others which may exist elsewhere so that user can better control what they get. * meta.autodep.mk (NO_FILEMON_COOKIE): create a cookie if we ever build dir with nofilemon so that UPDATE_DEPENDFILE will be forced to NO until cleaned. 2016-04-01 Simon J. Gerraty * install-mk (MK_VERSION): 20160401 * meta2deps.py: fix old print statement when debugging. * gendirdeps.mk: META2DEPS_CMD append M2D_EXCLUDES with -X patch from Bryan Drewery 2016-03-22 Simon J. Gerraty * install-mk (MK_VERSION): 20160317 (St. Pats) * warnings.mk: g++ does not like -Wimplicit * sys.mk sys/*.mk lib.mk prog.mk: use CXX_SUFFIXES to handle the pelthora of common suffixes for C++ * lib.mk: use .So for shared objects 2016-03-15 Simon J. Gerraty * install-mk (MK_VERSION): 20160315 * meta.stage.mk (LN_CP_SCRIPT): do not ln(1) if we have to chmod(1) normally only applies to scripts. * dirdeps.mk: NO_DIRDEPS_BELOW to supress DIRDEPS below RELDIR as well as outside it. 2016-03-10 Simon J. Gerraty * install-mk (MK_VERSION): 20160310 * dirdeps.mk: use targets rather than a list to track DIRDEPS that we have processed; the list gets very inefficient as number of DIRDEPS gets large. * sys.dependfile.mk: fix comment wrt MACHINE * meta.autodep.mk: ignore staged DPADDs when bootstrapping. patch from Bryan Drewery 2016-03-02 Simon J. Gerraty * meta2deps.sh: don't ignore subdirs. patch from Bryan Drewery 2016-02-26 Simon J. Gerraty * install-mk (MK_VERSION): 20160226 * gendirdeps.mk: mark _DEPENDFILE .NOMETA 2016-02-20 Simon J. Gerraty * dirdeps.mk: we shouldn't normally include .depend but if we do use .dinclude if we can. 2016-02-18 Simon J. Gerraty * install-mk (MK_VERSION): 20160218 * sys.clean-env.mk: with recent change to Var_Subst() we cannot use the '$$' trick, but .export-literal does the job we need. * auto.dep.mk: make use .dinclude if we can. 2016-02-05 Simon J. Gerraty * dirdeps.mk: Add _build_all_dirs such that local.dirdeps.mk can add fully qualified dirs to it. These will be built normally but the current DEP_RELDIR will not depend on then (to avoid cycles). This makes it easy to hook things like unit-tests into build. 2016-01-21 Simon J. Gerraty * dirdeps.mk: add bootstrap-empty 2015-12-12 Simon J. Gerraty * install-mk (MK_VERSION): 20151212 * auto.obj.mk: do not require MAKEOBJDIRPREFIX to exist. only apply :tA to __objdir when comparing to .OBJDIR 2015-11-14 Simon J. Gerraty * install-mk (MK_VERSION): 20151111 * meta.sys.mk: include sys.dependfile.mk * sys.mk (OPTIONS_DEFAULT_NO): use options.mk to set MK_AUTO_OBJ and MK_DIRDEPS_BUILD include local.sys.env.mk early include local.sys.mk later * own.mk (OPTIONS_DEFAULT_NO): AUTO_OBJ etc moved to sys.mk 2015-11-13 Simon J. Gerraty * meta.sys.mk (META_COOKIE_TOUCH): add ${META_COOKIE_TOUCH} to the end of scripts to touch cookie * meta.stage.mk: stage_libs should ignore SYMLINKS. 2015-10-23 Simon J. Gerraty * install-mk (MK_VERSION): 20151022 * sys.mk: BSD/OS does not have 'type' as a shell builtin. 2015-10-20 Simon J. Gerraty * install-mk (MK_VERSION): 20151020 * dirdeps.mk: Add logic for make -f dirdeps.mk some/dir.${TARGET_SPEC} 2015-10-14 Simon J. Gerraty * install-mk (MK_VERSION): 20151010 2015-10-02 Simon J. Gerraty * meta.stage.mk: use staging: ${STAGE_TARGETS:... to have stage_lins run last in non-jobs mode. Use .ORDER only for jobs mode. 2015-09-02 Simon J. Gerraty * rst2htm.mk: allow for per target flags etc. 2015-09-01 Simon J. Gerraty * install-mk (MK_VERSION): 20150901 * doc.mk: create dir if needed use DOC_INSTALL_OWN 2015-06-15 Simon J. Gerraty * install-mk (MK_VERSION): 20150615 * auto.obj.mk: allow use of MAKEOBJDIRPREFIX too. Follow make's normal precedence rules. * gendirdeps.mk: allow customization of the header. eg. for FreeBSD: GENDIRDEPS_HEADER= echo '\# ${FreeBSD:L:@v@$$$v$$ @:M*F*}'; * meta.autodep.mk: ignore dirdeps.cache* * meta.stage.mk: when bootstrapping options it can be handy to throw warnings rather than errors for staging conflicts. * meta.sys.mk: include local.meta.sys.mk for customization 2015-06-06 Simon J. Gerraty * install-mk (MK_VERSION): 20150606 * dirdeps.mk: don't rely on manually maintained Makefile.depend to set DEP_RELDIR and reset DIRDEPS. By setting DEP_RELDIR ourselves we can skip :tA * gendirdeps.mk: skip setting DEP_RELDIR. 2015-05-24 Simon J. Gerraty * dirdeps.mk: avoid wildcards like make(bootstrap*) 2015-05-20 Simon J. Gerraty * install-mk (MK_VERSION): 20150520 * dirdeps.mk: when we are building dirdeps cache file we *want* meta_oodate to look at all the Makefile.depend files, so set .MAKE.DEPENDFILE to something that won't match. * meta.stage.mk: for STAGE_AS_* basename of file may not be unique so first use absolute path as key. Also skip staging at level 0. 2015-04-30 Simon J. Gerraty * install-mk (MK_VERSION): 20150430 * dirdeps.mk: fix _count_dirdeps for non-cache case. 2015-04-16 Simon J. Gerraty * install-mk (MK_VERSION): 20150411 bump version * own.mk: put AUTO_OBJ in OPTIONS_DEFAULT_NO rather than YES. it is here mainly for documentation purposes, since if using auto.obj.mk it is better done via sys.mk 2015-04-01 Simon J. Gerraty * install-mk (MK_VERSION): 20150401 * meta2deps.sh: support @list * meta2deps.py: updates from Juniper o add EXCLUDES o skip bogus input files. o treat 'M' and 'L' as both an 'R' and a 'W' 2015-03-03 Simon J. Gerraty * install-mk (MK_VERSION): 20150303 * dirdeps.mk: if MK_DIRDEPS_CACHE is yes, use dirdeps-cache which is built via sub-make so we have a .meta file to tell if it is out-of-date. The dirdeps-cache contains the same dependency rules that we normaly construct on the fly. This adds a few seconds overhead when the cache is out of date, but for a large target, the savings can be significant (10-20min). 2014-11-18 Simon J. Gerraty * install-mk (MK_VERSION): 20141118 * meta.stage.mk: add stale_staged * dirdeps.mk (_DIRDEP_USE_LEVEL): allow this to be tweaked only useful under very rare conditions such as FreeBSD's make universe. * auto.obj.mk: Allow MK_AUTO_OBJ to set MKOBJDIRS=auto 2014-11-11 Simon J. Gerraty * install-mk (MK_VERSION): 20141111 * mkopt.sh: use consistent semantics for _mk_opt and _mk_opts 2014-11-09 Simon J. Gerraty * FILES: include mkopt.sh which allows handling options in shell scripts in a manner compatible with options.mk 2014-10-12 Simon J. Gerraty * meta.stage.mk: ensure only _STAGED_DIRS under objroot are used for GENDIRDEPS_FILTER to avoid surprises. 2014-10-10 Simon J. Gerraty * dirdeps.mk (NSkipHostDir): this needs SRCTOP prepended since by the time it is applied to __depdirs they have. * dirdeps.mk fix filtering of _machines since M_dep_qual_fixes expects patterns like *.${MACHINE} * cython.mk (pyprefix?): use pyprefix to find python bits since prefix might be something else (where we install our stuff) 2014-09-11 Simon J. Gerraty * install-mk (MK_VERSION): 20140911 * dirdeps.mk: add bootstrap target to simplify adding support for new MACHINE. 2014-09-01 Simon J. Gerraty * gendirdeps.mk: Add handling of GENDIRDEPS_FILTER_DIR_VARS and GENDIRDEPS_FILTER_VARS to make it easier to produce sharable Makefile.depend files. 2014-08-28 Simon J. Gerraty * install-mk (MK_VERSION): 20140828 * cython.mk: capture logic for building python extension modules with Cython. 2014-08-08 Simon J. Gerraty * meta.stage.mk (_STAGE_AS_BASENAME_USE): Add StageAs variant 2014-08-02 Simon J. Gerraty * install-mk (MK_VERSION): 20140801 * dep.mk: use explicit MKDEP_MK rather than overload MKDEP to identify the autodep.mk variant. * sys.dependfile.mk: delete .MAKE.DEPENDFILE if its initial value does not match .MAKE.DEPENDFILE_PREFIX * meta.autodep.mk: if _bootstrap_dirdeps add RELDIR to DIRDEPS 2014-05-22 Simon J. Gerraty * install-mk (MK_VERSION): 20140522 * lib.mk: use CC to link shlib for linux too patch from Brendan MacDonell 2014-05-05 Simon J. Gerraty * meta.autodep.mk: add _reldir_{finish,failed} for gathering stats if WITH_META_STATS is defined. 2014-05-02 Simon J. Gerraty * dirdeps.mk: accept -DWITHOUT_DIRDEPS (same a as -DNO_DIRDEPS) to supress dirdeps outside of .CURDIR. 2014-04-05 Simon J. Gerraty * Fix spelling errors - patch from Pedro Giffuni 2014-03-14 Simon J. Gerraty * install-mk (MK_VERSION): 20140314 * dirdeps.mk (beforedirdeps): a handy hook * dirdeps.mk (DIRDEP_MAKE): allow the actual command we run to visit leaf dirs to be intercepted (eg. for distributed build). * dirdeps.mk (__depdirs): ensure // don't sneak in * gendirdeps.mk (DIRDEPS): ensure // don't sneak in 2014-02-21 Simon J. Gerraty * rst2htm.mk (RST2PDF): add support for rst2pdf 2014-02-14 Simon J. Gerraty * install-mk (MK_VERSION): bump version * dirdeps.mk (_last_dependfile): use .INCLUDEDFROMFILE if available. 2014-02-10 Simon J. Gerraty * options.mk: avoid :U so this isn't bmake dependent 2014-02-09 Simon J. Gerraty * options.mk: cleanup and simplify semanitcs NO_* dominates all, if both WITH_* and WITHOUT_* are defined then result is DOMINATE_* which defaults to "no". Ie. WITHOUT_ normally wins. 2013-12-12 Simon J. Gerraty * install-mk (MK_VERSION): bump version * meta2deps.py: convert to print function for python3 compat. we also need to open files with mode 'r' rather than 'rb' otherwise we get bytes instead of strings. 2013-10-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version * dirdeps.mk: when TARGET_SPEC_VARS is more than just MACHINE apply the same filtering (M_dep_qual_fixes) when setting _machines as _build_dirs. Also fix the filtering of Makefile.depend files - for reporting what we are looking for (M_dep_qual_fixes can get confused by Makefile.depend) Add some more debug info. 2013-09-04 Simon J. Gerraty * gendirdeps.mk (_objtops): fix typo also while processing M2D_OBJROOTS to gather qualdir_list qualify $ql with loop iterator to ensure correct results. 2013-08-01 Simon J. Gerraty * install-mk (MK_VERSION): 20130801 * libs.mk: update to match progs.mk 2013-07-26 Simon J. Gerraty * install-mk (MK_VERSION): 20130726 some updates from Juniper and FreeBSD o meta2deps.py: indicate file and line number when we hit parse errors also allow @file to provide huge list of .meta files. * meta2deps.py: add try_parse() to cleanup the above. 2013-07-16 Simon J. Gerraty * install-mk (MK_VERSION): 20130716 * own.mk: add GPROG as an option * prog.mk: honor MK_GPROF==yes 2013-05-10 Simon J. Gerraty * install-mk (MK_VERSION): 20130505 * gendirdeps.mk, meta2deps.py, meta2deps.sh: handle $TARGET_SPEC for when $MACHINE isn't enough for objdir distinction. Bring meta2deps.sh closer to par with meta2deps.py. 2013-04-18 Simon J. Gerraty * meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all' also if the target 'beforeinstall' exists, make it depend on .dirdep (incase it uses STAGE_INSTALL). 2013-04-17 Simon J. Gerraty * install-mk (MK_VERSION): 20130401 ;-) * meta.stage.mk (STAGE_INSTALL_SH): add stage-install.sh as wrapper around install(1). * options.mk (OPTION_PREFIX): Allow a prefix other than MK_ 2013-03-30 Simon J. Gerraty * meta2deps.py (MetaFile.__init__): ensure self.cwd is initialized. * install-mk (MK_VERSION): bump version 2013-03-21 Simon J. Gerraty * install-mk (MK_VERSION): bump version * gendirdeps.mk: do not apply :tA to DPADD entries, since we lose any trailing /., rather apply :tA only when needed. * gendirdeps.mk: better mimic meta2deps handling of .dirdep files. * meta.stage.mk (LN_CP_SCRIPT): Add LnCp to do the ln||cp dance consistently. * dirdeps.mk: better describe the dance in sys.mk for TARGET_SPEC. 2013-03-18 Simon J. Gerraty * gendirdeps.mk: revert the dance around .MAKE.DEPENDFILE_DEFAULT it is simpler to just not update when say building for "host" (where we know we apply filters to DIRDEPS), and using a non-machine qualified dependfile. 2013-03-16 Simon J. Gerraty * dirdeps.mk: improve DIRDEPS filtering by allowing DEP_SKIP_DIR and DEP_DIRDEPS_FILTER to vary by DEP_MACHINE and DEP_TARGET_SPEC * gendirdeps.mk: ensure _objroot has trailing / if it needs it. * meta2deps.py: if machine is "host", then also trim self.host_target from any OBJROOTS. 2013-03-11 Simon J. Gerraty * gendirdeps.mk: if .MAKE.DEPENDFILE_DEFAULT is not machine qualified but _DEPENDFILE is, and .MAKE.DEPENDFILE_DEFAULT exists but _DEPENDFILE does not, compare the new _DEPENDFILE against .MAKE.DEPENDFILE_DEFAULT and discard if the same. 2013-03-08 Simon J. Gerraty * meta.stage.mk: use STAGE_TARGETS to control .ORDER and hook to all: via staging: 2013-03-07 Simon J. Gerraty * sys.dependfile.mk (.MAKE.DEPENDFILE_DEFAULT): use a separate variable for the default .MAKE.DEPENDFILE value so that it can be controlled independently of .MAKE.DEPENDFILE_PREFERENCE * meta.stage.mk: throw error if cp fails etc. Stage*() return early if passed no args. .ORDER stage_* 2013-03-03 Simon J. Gerraty * install-mk (MK_VERSION): bump version * gendirdeps.mk: handle multiple M2D_OBJROOTS better. 2013-02-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20130210 * import latest dirdeps.mk, gendirdeps.mk and meta2deps.py from Juniper. o dirdeps.mk now fully supports TARGET_SPEC consisting of more than just MACHINE. o no longer use DEP_MACHINE from Makefile.depend* so remove it. 2013-01-23 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20130123 * meta.stage.mk: add stage_links (hard links). if doing hard links, we add dest to link as well. Default the stage dir for [sym]links to STAGE_OBJTOP since these are typically specified as absolute paths. Add -m "mode" flag to StageFiles and StageAs. 2012-11-11 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121111 * autoconf.mk: avoid meta mode seeing changed commands for config.status * meta.autodep.mk: pass resolved MAKESYSPATH to gendirdeps in case we were found via .../mk * sys.clean-env.mk: move it from examples, we and others use it "as is". * FILES: add srctop.mk and options.mk * own.mk: convert to using options.mk which is modeled after FreeBSD's handling of MK_* but more flexible. This allows MK_* for boolean knobs to not be confused with MK* which can be commands. * examples/sys.clean-env.mk: add WITH[OUT]_ to MAKE_ENV_SAVE_PREFIX_LIST. Mention that HOME=/var/empty might be a good idea. 2012-11-08 Simon J. Gerraty * sys.dependfile.mk: if not depend file exists, $MACHINE specific ones are supported but not the default, check if any exist and follow suit. 2012-11-06 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121106 2012-11-05 Simon J. Gerraty * import latest dirdeps.mk and meta2deps.py from Juniper. * progs.mk: add MAN and CXXFLAGS to PROG_VARS also add PROGS_TARGETS and pass on PROG_CXX if it seems appropriate. 2012-11-04 Simon J. Gerraty * meta.stage.mk: update CLEANFILES remove redundant cp of .dirdep from STAGE_AS_SCRIPT. * progs.mk: Add LDADD to PROG_VARS 2012-10-12 Simon J. Gerraty * meta.stage.mk (STAGE_DIR_FILTER): track dirs we stage to in _STAGED_DIRS so that these can be turned into filters for GENDIRDEPS_FILTER. 2012-10-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121010 * meta.stage.mk (STAGE_DIRDEP_SCRIPT): check that an existing target.dirdep matches .dirdep 2012-08-08 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20120808 * import latest meta2deps.py from Juniper. 2012-07-11 Simon J.

Gerraty * install-mk (MK_VERSION): bump version to 20120626 * meta.sys.mk: ignore PYTHON if it does not exist compare ${.MAKE.DEPENDFILE:E} against ${MACHINE} is more reliable. * meta.stage.mk: examine .MAKE.DEPENDFILE_PREFERENCE for any entries ending in .${MACHINE} to decide if qualified _dirdep is needed. * gendirdeps.mk: only produce unqualified deps if no .MAKE.DEPENDFILE_PREFERENCE ends in .${MACHINE} * meta.subdir.mk: apply SUBDIRDEPS_FILTER 2012-04-20 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20120420 * add sys.dependfile.mk so we can experiment with .MAKE.DEPENDFILE_PREFERENCE * meta.autodep.mk: _DEPENDFILE is precious! 2012-03-15 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20120315 * install-new.mk: avoid being interrupted 2012-02-26 Simon J. Gerraty * man.mk: MAN might have multiple values so be careful with exists(). 2012-01-19 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20120112 * fix examples/sys.clean-env.mk so that MAKEOBJDIR is handled as: MAKEOBJDIR='${.CURDIR:S,${SRCTOP},${OBJTOP},}' 2011-12-03 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111201 * import dirdeps.mk from Juniper sjg@ o more consistent handling of DEP_MACHINE, especially when dealing with an odd Makefile.depend, when normally using Makefile.depend.${MACHINE} 2011-11-22 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111122 * meta.autodep.mk: add some debug output, be more crisp about updating. Use ${.ALLTARGETS:M*.o} as a clue for .depend 2011-11-13 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111111 it's too cool to miss * import meta* updates from Juniper sjg@ o dirdeps.mk set DEP_MACHINE for Makefile.depend (when we are normally using Makefile.depend.${MACHINE}), handy for read-only manually maintained dependencies. o meta2deps.py add a clear 'ERROR:' token if an exception is raised. o gendirdeps.mk if ERROR: from meta2deps.py do not update anything. 2011-10-30 Simon J. Gerraty * install-new.mk separate the cmp and copy logic to its own function. 2011-10-28 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111028 * sys.mk: include auto.obj.mk if MKOBJDIRS is set to auto * subdir.mk: ensure _SUBDIRUSE is provided * meta.autodep.mk: remove dependency of gendirdeps.mk on auto.obj.mk * meta.subdir.mk: always allow for Makefile.depend 2011-10-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111010 o minor tweak to *dirdeps.mk from Juniper sjg@ 2011-10-01 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20111001 o add meta2deps.py from Juniper sjg@ o tweak gendirdeps.mk to work with meta2deps.py when not cross-building * autoconf.mk: add autoconf-input as a hook for regenerating AUTOCONF_INPUTS (configure). 2011-08-24 Simon J. Gerraty * meta.autodep.mk: if we do not have OBJS, .depend isn't a useful trigger for updating Makefile.depend* 2011-08-08 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20110808 * obj.mk: minor cleanup * auto.obj.mk: improve description of Mkdirs and honor NO_OBJ too. 2011-08-01 Simon J. Gerraty * auto.obj.mk (.OBJDIR): throw an error if we cannot use the specified dir. 2011-06-28 Simon J. Gerraty * meta.autodep.mk: if XMAKE_META_FILE is set the makefile uses a foreign make, and so dependencies can only be gathered from a clean tree build. 2011-06-24 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20110622 * meta.autodep.mk: improve bootstraping 2011-06-10 Simon J.

Gerraty * install-mk (MK_VERSION): bump version to 20110606 * don't store SRC_DIRDEPS in Makefile.depend* by default not everyone needs it. 2011-05-04 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20110505 first release including meta mode makefiles 2011-05-02 Simon J. Gerraty * meta.stage.mk: add STAGE_AS_SETS and stage_as for things that need to be staged with different names. 2011-05-01 Simon J.

Gerraty * rst2htm.mk: convert rst to s5 (slides) or plain html depending on target name. 2011-03-30 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20110330 2011-03-29 Simon J. Gerraty * sys.mk (_DEBUG_MAKE_FLAGS): use indirection so that DEBUG_MAKE_FLAGS0 can be used to debug level 0 only and DEBUG_MAKE_FLAGS for the rest. * sys.mk: re-define M_whence in terms of M_type. M_type is useful for checking if something is a builtin. 2011-03-16 Simon J. Gerraty * meta.stage.mk: add stage_symlinks and leverage StageLinks for stage_libs 2011-03-10 Simon J. Gerraty * dirdeps.mk: correct value for _depdir_files depends on .MAKE.DEPENDFILE Add our copyright - just to make it clear we have frobbed this quite a bit. DEP_MACHINE needs to be set to MACHINE each time, if using only Makefile.depend (cf. Makefile.depend.${MACHINE}) * meta.stage.mk: meta mode version of staging * init.mk, final.mk: include local.*.mk to simplify customization 2011-03-03 Simon J. Gerraty * auto.obj.mk: just because we are doing mk destroy, we should still set .OBJDIR correctly if it exists. * install-mk (mksrc): do not exclude meta.sys.mk 2011-03-01 Simon J. Gerraty * host-target.mk: set/export _HOST_ARCH etc separately, catch junk resulting from uname -p, so we can find sys/Linux.mk correctly. 2011-02-18 Simon J. Gerraty * meta.sys.mk: throw an error if /dev/filemon is missing and we expected to be updating Makefile.depend* 2011-02-14 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20110214 * meta.subdir.mk: add support for -DBOOTSTRAP_DEPENDFILES 2010-09-25 Simon J. Gerraty * meta.sys.mk: not valid for older bmake 2010-09-24 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100919 include dirdeps.mk et al from Juniper Networks, for meta mode - requires filemon(9). * sys.mk, subdir.mk: Add hooks for meta mode. we do this as meta.sys.mk, meta.autodep.mk and meta.subdir.mk to make turning it on/off simple. 2010-06-16 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100616 * fix typo in sys.mk 2010-06-12 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100612 * lib.mk: remove duplicate addition to SOBJS 2010-06-10 Simon J. Gerraty * sys.mk: Add a means of selectively turning on debug flags. Eg. DEBUG_MAKE_FLAGS=-dv DEBUG_MAKE_DIRS="*lib/sjg" will act as if we did make -dv if .CURDIR ends in lib/sjg DEBUG_MAKE_SYS_DIRS does the same thing, but we set the flags at the start of sys.mk rather than the end. This only makes sense for leaf dirs, so we check that .MAKE.LEVEL > 0 2010-06-09 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100608 * sys.mk: include sys.env.mk later so it can use M_ListToSkip et al. * examples/sys.clean-env.mk: require MAKE_VERIONS >= 20100606 also make it easier for folk to tweak 2010-06-08 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100606 do not install examples/* * FILES: add examples/sys.clean-env.mk * examples/sys.clean-env.mk: use .export-env to handle MAKEOBJDIR this requires bmake-20100606 or later to work. 2010-05-13 Simon J. Gerraty * sys.mk (M_tA): better simulate the result of :tA if not available. 2010-05-04 Simon J. Gerraty * sys.mk: canonicalize MAKE_VERSION old versions reported bmake- build- whereas we only care about 2010-04-25 Simon J. Gerraty * install-mk: just warn about FORCE_{BSD,SYS}_MK being ignored * lib.mk: we only build the shared lib if SHLIB_FULLVERSION is !empty 2010-04-22 Simon J.

Gerraty * install-mk (MK_VERSION): bump version to 20100404 * subdir.mk: protect from multiple inclusion using _SUBDIRUSE. * obj.mk: protect from multiple inclusion even as bsd.obj.mk Also create a target _SUBDIRUSE so that we can be used without subdir.mk 2010-04-12 Simon J. Gerraty * dep.mk: use <> when .including so can override. 2010-01-11 Simon J. Gerraty * lib.mk (SHLIB_LINKS): ensure a string comparison. 2010-01-04 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20100102 * own.mk: ensure PRINTOBJDIR works * autoconf.mk: pass on CONFIGURE_ARGS * init.mk: handle COPTS.${.IMPSRC:T} etc. * lib.mk: allow sys.mk to control SHLIB_FULLVERSION fix handling of symlinks for darwin * libnames.mk: add DSHLIBEXT for libs which only exist as shared. * man.mk: suppress chown when not root. * rst2htm.mk: allow srcs from multiple locations. * sys.mk: M_whence, stop after 1st line of output. * sys/Darwin.mk: Use .dylib for DSHLIBEXT and HOST_LIBEXT * sys/SunOS.mk: we need to export PATH 2009-12-23 Simon J. Gerraty * install-mk (MK_VERSION): bump version include rst2htm.mk 2009-12-17 Simon J. Gerraty * sys.mk,libnames.mk add .-include this allows local customization without the need to edit the distributed files. 2009-12-14 Simon J. Gerraty * dpadd.mk (__dpadd_libdirs): order -L's to avoid picking up older versions already installed. 2009-12-13 Simon J. Gerraty * stage.mk (.stage-install): generalize lib.mk's .libinstall * rules.mk rules for generic Makefile. * inc.mk install for includes. 2009-12-11 Simon J.

Gerraty * install-mk (MK_VERSION): bump version * lib.mk: if sys.mk doesn't give us an lorder, don't use it. based on patch from Greg Olszewski. * Generic.sys.mk: if we have nothing to work with set LORDER etc only if we can find it. 2009-09-08 Simon J. Gerraty * install-mk (MK_VERSION): bump version * man.mk: cleanman: remove CLEANMAN if defined. 2009-09-04 Simon J. Gerraty * SunOS.5.sys.mk (CC): Use ?= like the other *sys.mk 2009-07-17 Simon J. Gerraty * install-mk (MK_VERSION): bump version include auto.obj.mk 2009-03-26 Simon J. Gerraty * prog.mk,lib.mk: ensure test of USE_DPADD_MK doesn't fail. 2008-11-11 Simon J.

Gerraty * install-mk (MK_VERSION): 20030930 * rename generic.sys.mk to Generic.sys.mk so that it does not get installed (unless being used as sys.mk) * set OS and ROOT_GROUP for those that we know the value. for others (eg. Generic.sys.mk) wrap the != in an .ifndef so we don't do it again for each sub-make. 2003-09-28 Simon J. Gerraty * install-mk (MK_VERSION): 20030928 Add some extra *.sys.mk from bootstrap-pkgsrc some of these likely still need work. Make everything default to root:wheel ownership, sys.mk can set ROOT_GROUP accordingly. 2003-08-07 Simon J. Gerraty * install-mk: if FORCE_BSD_MK={cp,ln} use the ones in SYS_MK_DIR not the portable ones. 2003-07-31 Simon J. Gerraty * install-mk: add ability to use cp -f when updating destination .mk files. Also now possible to play games with FORCE_SYS_MK=ln etc on *BSD machines to link /usr/share/mk/sys.mk into dest - not recommended unless you seriously want to. 2003-07-28 Simon J.

We use Makefile.depend (default value for # .MAKE.DEPENDFILE_PREFIX) to refer to these makefiles to # distinguish them from others. # # Before each Makefile.depend file is read, we set # DEP_RELDIR to be the RELDIR (path relative to SRCTOP) for # its directory, and DEP_MACHINE etc according to the . # represented by the suffix of the corresponding target. # # Since each Makefile.depend file includes dirdeps.mk, this # processing is recursive and results in .MAKE.LEVEL 0 learning the # dependencies of the tree wrt the initial directory (_DEP_RELDIR). # # NOTE: given the extent of processing that DIRDEPS undergoes it # is important that any variables in entries use :U to guard # against surprises when undefined. # # TARGET_SPEC_VARS # The default value is just MACHINE, and for most environments # this is sufficient. The _DIRDEP_USE target actually sets # both MACHINE and TARGET_SPEC to the suffix of the current # target so that in the general case TARGET_SPEC can be ignored. # # If more than MACHINE is needed then sys.mk needs to decompose # TARGET_SPEC and set the relevant variables accordingly. # It is important that MACHINE be included in and actually be # the first member of TARGET_SPEC_VARS. This allows other # variables to be considered optional, and some of the treatment # below relies on MACHINE being the first entry. # Note: TARGET_SPEC cannot contain any '.'s so the target # triple used by compiler folk won't work (directly anyway). # # For example: # # # Always list MACHINE first, # # other variables might be optional. # TARGET_SPEC_VARS = MACHINE TARGET_OS # .if ${TARGET_SPEC:Uno:M*,*} != "" # _tspec := ${TARGET_SPEC:S/,/ /g} # MACHINE := ${_tspec:[1]} # TARGET_OS := ${_tspec:[2]} # # etc. # # We need to stop that TARGET_SPEC affecting any submakes # # and deal with MACHINE=${TARGET_SPEC} in the environment. # TARGET_SPEC = # # export but do not track # .export-env TARGET_SPEC # .export ${TARGET_SPEC_VARS} # .for v in ${TARGET_SPEC_VARS:O:u} # .if empty($v) # .undef $v # .endif # .endfor # .endif # # make sure we know what TARGET_SPEC is # # as we may need it to find Makefile.depend* # TARGET_SPEC = ${TARGET_SPEC_VARS:@v@${$v:U}@:ts,} # # The following variables can influence the initial DIRDEPS # computation with regard to the TARGET_SPECs that will be # built. # Most should also be considered by init.mk # # ONLY_TARGET_SPEC_LIST # Defines a list of TARGET_SPECs for which the current # directory can be built. # If ALL_MACHINES is defined, we build for all the # TARGET_SPECs listed. # # ONLY_MACHINE_LIST # As for ONLY_TARGET_SPEC_LIST but only specifies # MACHINEs. # # NOT_TARGET_SPEC_LIST # A list of TARGET_SPECs for which the current # directory should not be built. # # NOT_MACHINE_LIST # A list of MACHINEs the current directory should not be # built for. # # DIRDEPS_EXPORT_VARS (DEP_EXPORT_VARS) # It is discouraged, but sometimes necessary for a # Makefile.depend file to influence the environment. # Doing this is correctly (especially if using DIRDEPS_CACHE) is # tricky so a Makefile.depend file can set DIRDEPS_EXPORT_VARS # and dirdeps.mk will do the deed: # # MK_UEFI = yes # DIRDEPS_EXPORT_VARS = MK_UEFI # # _build_xtra_dirs # local.dirdeps.mk can add targets to this variable. # They will be hooked into the build, but independent of # any other DIRDEP. # # This allows for adding TESTS to the build, such that the build # if any test fails, but without the risk of introducing # circular dependencies. -now_utc ?= ${%s:L:gmtime} +now_utc ?= ${%s:L:localtime} .if !defined(start_utc) start_utc := ${now_utc} .endif .if !target(bootstrap) && (make(bootstrap) || \ make(bootstrap-this) || \ make(bootstrap-recurse) || \ make(bootstrap-empty)) # disable most of below .MAKE.LEVEL = 1 .endif # touch this at your peril _DIRDEP_USE_LEVEL?= 0 .if ${.MAKE.LEVEL} == ${_DIRDEP_USE_LEVEL} # only the first instance is interested in all this # the first time we are included the _DIRDEP_USE target will not be defined # we can use this as a clue to do initialization and other one time things. .if !target(_DIRDEP_USE) # do some setup we only need once _CURDIR ?= ${.CURDIR} _OBJDIR ?= ${.OBJDIR} .if ${MAKEFILE:T} == ${.PARSEFILE} && empty(DIRDEPS) && ${.TARGETS:Uall:M*[/.]*} != "" # This little trick let's us do # # mk -f dirdeps.mk some/dir.${TARGET_SPEC} # all: ${.TARGETS:Nall}: all DIRDEPS := ${.TARGETS:M*[/.]*} # so that -DNO_DIRDEPS works DEP_RELDIR := ${DIRDEPS:[1]:R} # this will become DEP_MACHINE below TARGET_MACHINE := ${DIRDEPS:[1]:E:C/,.*//} .if ${TARGET_MACHINE:N*/*} == "" TARGET_MACHINE := ${MACHINE} .endif # disable DIRDEPS_CACHE as it does not like this trick MK_DIRDEPS_CACHE = no # incase anyone needs to know _dirdeps_cmdline: .endif # make sure we get the behavior we expect .MAKE.SAVE_DOLLARS = no # make sure these are empty to start with _DEP_TARGET_SPEC = # If TARGET_SPEC_VARS is other than just MACHINE # it should be set by sys.mk or similar by now. # TARGET_SPEC must not contain any '.'s.

You need bmake_ or a *recent* NetBSD_ make. If in doubt use bmake_. Introduction ============ Many years ago, when building large software projects, I used GNU make (or my own patched version of it), and had developed a set of macros to simplify developing complex build trees. Since the early 90's my main development machines, run BSD (NetBSD_ to be precise, and more recently FreeBSD), and the BSD source tree is good example of a large software project. It quickly became clear that ``/usr/share/mk/*.mk`` were a great model, but at the time were quite tightly linked to building the BSD tree. Much as I liked using NetBSD, my customers were more likely to be using SunOS, HP-UX etc, so I started on bmake_ and a portable collection of mk-files (mk.tar.gz_). NetBSD provided much of the original structure. Since then I've added a lot of features to NetBSD's make and hence to bmake which is kept closely in sync. The mk-files however have diverged quite a bit, though ideas are still picked up from NetBSD and FreeBSD. Basics ------ The BSD build model is very simple. A directory produces one component, which is generally either a library or a program. Library makefiles include ``lib.mk`` and programs include ``prog.mk`` and they *do the right thing*. A simple library makefile might look like:: LIB = sig SRCS = \ sigaction.c \ sigcompat.c \ sighdl.c .include a simple program makefile:: PROG = cat SRCS = cat.c .include in such cases even the ``SRCS`` line is unnecessary as ``prog.mk`` will default it to ``${PROG}.c``. It is the sensible use of defaults and the plethora of macro modifiers provided by bmake_ that allow simple makefiles such as the above to *just work* on many different systems. mk-files ======== This section provides a brief description of some of the ``*.mk`` files. +The makefiles ``lib.mk``, ``prog.mk``, ``init.mk``, ``own.mk``, +``dep.mk`` and ``man.mk`` are more or less equivalent to ``bsd.*.mk`` +found in BSD, and when installed on non-BSD platforms get symlinked as +``bsd.*.mk`` as well. + +The other makefiles (apart from ``sys.mk``) can be used in conjunction +with ``bsd.*.mk`` on BSD. + sys.mk ------ When bmake starts, it looks for ``sys.mk`` and reads it before doing anything else. Thus, this is the place to setup the environment for everyone else. In this distribution, ``sys.mk`` avoids doing anything platform or site dependent. It is quite short, and includes a number of other files (which may or may not exists) sys.env.mk If it exists, is expected to do things like conditioning the environment. Since it will only be included by the initial instance of bmake, it should ``.export`` anything that sub-makes might need. examples/sys.clean-env.mk An example of how to clean the environment. See the file for all the details:: .if ${MAKE_VERSION} >= 20100606 && ${.MAKE.LEVEL} == 0 # we save any env var that starts with these MAKE_SAVE_ENV_PREFIX += SB MK MAKE MACHINE NEED_ CCACHE DISTCC USE_ SSH MAKE_SAVE_ENV_VARS += \ PATH HOME USER LOGNAME \ SRCTOP OBJTOP OBJROOT \ ${_env_vars} _env_vars != env | egrep '^(${MAKE_SAVE_ENV_PREFIX:ts|})' | sed 's,=.*,,'; echo _export_list = .for v in ${MAKE_SAVE_ENV_VARS:O:u} .if !empty($v) _export_list += $v $v := ${$v} .endif .endfor # now clobber the environment .unexport-env # list of vars that we handle specially below _tricky_env_vars = MAKEOBJDIR # export our selection - sans tricky ones .export ${_export_list:${_tricky_env_vars:${M_ListToSkip}}} # this next bit may need tweaking .if defined(MAKEOBJDIR) srctop := ${SRCTOP:U${SB_SRC:U${SB}/src}} objroot := ${OBJROOT:U${SB_OBJROOT:U${SB}/${SB_OBJPREFIX}}} # we'll take care of MACHINE below objtop := ${OBJTOP:U${objroot}${MACHINE}} .if !empty(objtop) # we would normally want something like (/bin/sh): # MAKEOBJDIR="\${.CURDIR:S,${SRCTOP},${OBJROOT}\${MACHINE},}" # the $$ below is how we achieve the same result here. # since everything saved from the environment above # has run through := we need to compensate for ${MACHINE} MAKEOBJDIR = $${.CURDIR:S,${srctop},${objtop:S,${MACHINE},\${MACHINE},},} # export these as-is, and do not track... .export-env ${_tricky_env_vars} # now evaluate for ourselves .for v in ${_tricky_env_vars} $v := ${$v} .endfor .endif .endif .endif host-target.mk Is used to set macros like ``HOST_TARGET``, ``HOST_OS`` and ``host_os`` which are used to find the next step. Note: since 20130303 bmake provides ``.MAKE.OS`` set to the equivalent of ``HOST_OS``. sys/\*.mk Platform specific additions, such as ``Darwin.mk`` or ``SunOS.mk`` set things like ``HOST_LIBEXT = .dylib`` for Darwin or ``SHLIB_FULLVERSION = ${SHLIB_MAJOR}`` for SunOS 5. If there is no OS specific file, ``sys/Generic.mk`` is used. local.sys.mk Any ``local.*.mk`` file is not part of the distribution. This provides a hook for sites to do extra setup without having to edit the distributed files. The above arrangement makes it easy for the mk files to be part of a src tree on an NFS volume and to allow building on multiple platforms. options.mk ---------- Inspired by FreeBSD's ``bsd.own.mk`` but more flexible. FreeBSD now have similar functionality in ``bsd.mkopt.mk``. It allows users to express their intent with respect to options ``MK_*`` by setting ``WITH_*`` or ``WITHOUT_*``. Note: ``WITHOUT_*`` wins if both are set, and makefiles can set ``NO_*`` to say they cannot handle that option, or even ``MK_*`` if they really need to. lib.mk ------ This file is used to build a number of different libraries from the same SRCS. ``lib${LIB}.a`` An archive lib of ``.o`` files, this is the default ``lib${LIB}_p.a`` A profiled lib of ``.po`` files. Still an archive lib, but all the objects are built with profiling in mind - hence the different extension. It is skipped if ``MK_PROFILE`` is "no". ``lib${LIB}_pic.a`` An archive of ``.so`` objects compiled for relocation. On NetBSD this is the input to ``lib${LIB}.${LD_so}``, it is skipped if ``MK_PIC`` or ``MK_PICLIB`` are "no". ``lib${LIB}.${LD_so}`` A shared library. The value of ``LD_so`` is very platform specific. For example:: # SunOS 5 and most other ELF systems libsslfd.so.1 # Darwin libsslfd.1.dylib This library will only be built if ``SHLIB_MAJOR`` has a value, and ``MK_PIC`` is not set to "no". There is a lot of platform specific tweaking in ``lib.mk``, largely the result of the original distributions trying to avoid interfering with the system's ``sys.mk``. libnames.mk ----------- This is included by both ``prog.mk`` and ``lib.mk`` and tries to include ``*.libnames.mk`` of which: ``local.libnames.mk`` does not exist unless you create it. It is a handy way for you to customize without touching the distributed files. For example, on a test machine I needed to build openssl but not install it, so put the following in ``local.libnames.mk``:: .if ${host_os} == "sunos" LIBCRYPTO = ${OBJTOP}/openssl/lib/crypto/libcrypto${DLIBEXT} LIBSSL = ${OBJTOP}/openssl/lib/ssl/libssl${DLIBEXT} INCLUDES_libcrypto = -I${OBJ_libcrypto} .endif The makefile created an openssl dir in ``${OBJ_libcrypto}`` to gather all the headers. dpadd.mk_ did the rest. ``host.libnames.mk`` contains logic to find any libs named in ``HOST_LIBS`` in ``HOST_LIBDIRS``. Each file above gets an opportunity to define things like:: LIBSSLFD ?= ${OBJTOP}/ssl/lib/sslfd/libsslfd${DLIBEXT} INCLUDES_libsslfd = -I${SRC_libsslfd}/h -I${OBJ_libslfd} these are used by dpadd.mk_ and will be explained below. dpadd.mk -------- This file looks like line noise, and is best considered read-only. However it provides some very useful functionality, which simplifies the build. Makefiles can use the LIB* macros defined via libnames.mk_ or anywhere else in various ways:: # indicate that we need to include headers from LIBCRYPTO # this would result in ${INCLUDES_libcrypto} being added to CFLAGS. SRC_LIBS += ${LIBCRYPTO} # indicate that libsslfd must be built already. # it also has the same effect as SRC_LIBS DPADD += ${LIBSSLFD} # indicate that not only must libsslfd be built, # but that we need to link with it. # this is almost exactly equivalent to # DPADD += ${LIBSSLFD} # LDADD += -L${LIBSSLFD:H} -lsslfd # and mostly serves to ensure that DPADD and LDADD are in sync. DPLIBS += ${LIBSSLFD} Any library (referenced by its full path) in any of the above, is added to ``DPMAGIC_LIBS`` with the following results, for each lib *foo*. ``SRC_libfoo`` Is set to indicate where the src for libfoo is. By default it is derived from ``LIBFOO`` by replacing ``${OBJTOP}`` with ``${SRCTOP}``. ``OBJ_libfoo`` Not very exciting, is just the dir where libfoo lives. ``INCLUDES_libfoo`` What to add to ``CFLAGS`` to find the public headers. The default varies. If ``${SRC_libfoo}/h`` exists, it is assumed to be the home of all public headers and thus the default is ``-I${SRC_libfoo}/h`` Otherwise we make no assumptions and the default is ``-I${SRC_libfoo} -I${OBJ_libfoo}`` ``LDADD_libfoo`` This only applies to libs reference via ``DPLIBS``. The default is ``-lfoo``, ``LDADD_*`` provides a hook to instantiate other linker flags at the appropriate point without losing the benfits of ``DPLIBS``. prog.mk ------- Compiles the specified SRCS and links them and the nominated libraries into a program. Prog makefiles usually need to list the libraries that need to be linked. We prefer use of ``DPLIBS`` but the more traditional ``DPADD`` and ``LDADD`` work just as well. That is:: DPLIBS += ${LIBCRYPTO} is equivalent to:: DPADD += ${LIBCRYPTO} LDADD += -lcrypto obj.mk ------ One of the cool aspects of BSD make, is its support for separating object files from the src tree. This is also the source of much confusion for people unfamiliar with it. Traditionally one had to do a separate ``make obj`` pass through the tree. If ``MK_AUTO_OBJ`` is set we include auto.obj.mk_. In fact if ``MKOBJDIRS`` is set to "auto", `sys.mk`_ will set ``MK_AUTO_OBJ=yes`` and include auto.obj.mk_ since it is best done early. auto.obj.mk ----------- Creates object dirs and leverages the ``.OBJDIR`` target introduced some years ago to NetBSD make, to use them. +Note that if ``auto.obj.mk`` is to be used it should be included +early - before bmake has established ``.PATH``, thus we include it +from ``sys.mk`` rather than ``obj.mk``. subdir.mk --------- This is the traditional means of walking the tree. A makefile sets ``SUBDIR`` to the list of sub-dirs to visit. If ``SUBDIR_MUST_EXIST`` is set, missing directories cause an error, otherwise a warning is issued. If you don't even want the warning, set ``MISSING_DIR=continue``. Traditionally, ``subdir.mk`` prints clues as it visits each subdir:: ===> ssl ===> ssl/lib ===> ssl/lib/sslfd you can suppress that - or enhance it by setting ``ECHO_DIR``:: # suppress subdir noise ECHO_DIR=: # print time stamps ECHO_DIR=echo @ `date "+%s [%Y-%m-%d %T] "` I prefer to use `dirdeps.mk`_ which makes ``subdir.mk`` irrelevant. links.mk -------- Provides rules for processing lists of ``LINKS`` and ``SYMLINKS``. Each is expected to be a list of ``link`` and ``target`` pairs (``link`` -> ``target``). The logic is generally in a ``_*_SCRIPT`` which is referenced in a ``_*_USE`` (``.USE``) target. The ``_BUILD_*`` forms are identical, but do not use ``${DESTDIR}`` and so are useful for creating symlinks during the build phase. For example:: SYMLINKS += ${.CURDIR}/${MACHINE_ARCH}/include machine header_links: _BUILD_SYMLINKS_USE md.o: header_links would create a symlink called ``machine`` in ``${.OBJDIR}`` pointing to ``${.CURDIR}/${MACHINE_ARCH}/include`` before compiling ``md.o`` autoconf.mk ----------- Deals with running (or generating) GNU autoconf ``configure`` scripts. dep.mk ------ Deals with collecting dependencies. Another useful feature of BSD make is the separation of this sort of information into a ``.depend`` file. ``MKDEP_CMD`` needs to point to a suitable tool (like mkdeps.sh_) If ``MK_AUTODEP`` is "yes" it sets ``MKDEP_MK`` to autodep.mk_ by default. ``MKDEP_MK`` can also be set to `auto.dep.mk`_ which is more efficient but does not support an explicit ``depend`` target. autodep.mk ---------- Leverages the ``-MD`` feature of recent GCC to collect dependency information as a side effect of compilation. With this GCC puts dependency info into a ``.d`` file. Unfortunately GCC bases the name of the ``.d`` file on the name of the input rather than the output file, which causes problems when the same source is compiled different ways. The latest GCC supports ``-MF`` to name the ``.d`` file and ``-MT`` to control the name to put as the dependent. Recent bmake allows dependencies for the ``.END`` target (run at the end if everything was successful), and ``autodep.mk`` uses this to post process the ``.d`` files into ``.depend``. auto.dep.mk ----------- A much simpler implementation than autodep.mk_ it uses ``-MF ${.TARGET:T}.d`` to avoid possible conflicts during parallel builds. This precludes the use of suffix rules to drive ``make depend``, so dep.mk_ handles that if specifically requested. If ``bmake`` is 20160218 or newer, ``auto.dep.mk`` uses ``.dinclude`` to includes the ``*.d`` files directly thus avoiding the need to create a ``.depend`` file from them. own.mk ------ Normally included by ``init.mk`` (included by ``lib.mk`` and ``prog.mk`` etc), sets macros for default ownership etc. It includes ``${MAKECONF}`` if it is defined and exists. ldorder.mk ---------- Leverages ``bmake`` to compute optimal link order for libraries. This works nicely and makes refactoring a breeze - so long as you have no (or few) cicular dependencies between libraries. Consider this experimental. man.mk ------ Deals with man pages. warnings.mk ----------- This provides a means of fine grained control over warnings on a per ``${MACHINE}`` or even file basis. A makefile sets ``WARNINGS_SET`` to name a list of warnings and individual ``W_*`` macros can be used to tweak them. For example:: WARNINGS_SET = HIGH W_unused_sparc = -Wno-unused would add all the warnings in ``${HIGH_WARNINGS}`` to CFLAGS, but on sparc, ``-Wno-unused`` would replace ``-Wunused``. You should never need to edit ``warnings.mk``, it will include ``warnings-sets.mk`` and/or ``local.warnings.mk`` to pick up customizations. rst2htm.mk ---------- Logic to simplify generating HTML (and PDF) documents from ReStructuredText. cython.mk --------- Logic to build Python C interface modules using Cython_ .. _Cython: http://www.cython.org/ cc-wrap.mk ---------- This makefile leverages two new features in bmake 20220126 and later. First is the ablity to set target local variables (GNU make has done this for ages). The second (only intersting if using `meta mode`_) allows filtering commands before comparison with previous run to decide if a target is out-of-date. In the past, making use of compiler wrappers like ``ccache``, ``distcc`` or the newer ``icecc`` could get quite ugly. Using ``cc-wrap.mk`` it could not be simpler. jobs.mk ------- This should be included by the top-level makefile. If you do:: make something-jobs then ``jobs.mk`` will run:: make -j${JOB_MAX} someting > ${JOB_LOGDIR}/something.log 2>&1 this ensures you get a build log and JOB_MAX is assumed to be set optimally for the host. META_MODE ========= The 20110505 and later versions of ``mk-files`` include a number of makefiles contributed by Juniper Networks, Inc. These allow the latest version of bmake_ to run in `meta mode`_ see `dirdeps.mk`_ and DIRDEPS_BUILD_ below. .. _`dirdeps.mk`: /help/sjg/dirdeps.htm .. _`meta mode`: bmake-meta-mode.htm DIRDEPS_BUILD ============= When the `meta mode`_ was originally done, there was no distinction between META_MODE_ and ``DIRDEPS_BUILD``, but as these were integrated into FreeBSD it became clear that META_MODE_ could be useful to many developers independently of ``DIRDEPS_BUILD``. Thus today we distinguish between the two.
