Gerraty * Makefile.in (BMAKE_VERSION): bump to 20040220 * Merge with NetBSD make, pick up: o fix for old :M parsing bug. o re-jigged unit-tests 2004-02-15 Simon J. 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 * Makefile.in (BMAKE_VERSION): bump version to 20040108 * Merge with NetBSD make, pick up: o fix for ternary modifier 2004-01-06 Simon J. Gerraty * Makefile.in (BMAKE_VERSION): bump version to 20040105 * Merge with NetBSD make, pick up: o fix for cond.c to handle compound expressions better o variable expansion within sysV style replacements 2003-12-22 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 $?' instead as it more accurately reflects the expected behavior and is more consistently implemented. o avoid use of asprintf. 2003-09-28 Simon J. Gerraty * util.c: Add asprintf and vasprintf. * Makefile.in (BMAKE_VERSION): bump version to 20030928 * Merge with NetBSD make, pick up: :[] modifier - allows picking words from a variable. :tW modifier - allows treating value as one big word. W flag for :C and :S - allows treating value as one big word. 2003-09-12 Simon J. Gerraty * Merge with NetBSD make pick up -de flag to enable printing failed command. don't skip 1st two dir entries (normally . and ..) since coda does not have them. 2003-09-09 Simon J. Gerraty * Makefile.in (BMAKE_VERSION): bump version to 20030909 * Merge with NetBSD make, pick up: - changes for -V '${VAR}' to print fully expanded value cf. -V VAR - CompatRunCommand now prints the command that failed. - several files got updated 3 clause Berkeley license. 2003-08-02 Simon J. Gerraty * boot-strap: Allow setting configure args on command line. 2003-07-31 Simon J. Gerraty * configure.in: add --with-defshell to allow sh or ksh to be selected as default shell. * Makefile.in: bump version to 20030731 * Merge with NetBSD make Pick up .SHELL spec for ksh and associate man page changes. 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. Pick unit-tests. 2003-07-23 Simon J. Gerraty * Makefile.in (BMAKE_VERSION): bump version to 20030723. * var.c (Var_Parse): fix bug in :ts modifier, after const correctness fixes, must pass nstr to VarModify. 2003-07-14 Simon J. Gerraty * Makefile.in: BMAKE_VERSION switch to a date based version. We'll generally use the date of last import from NetBSD. * Merge with NetBSD make Pick up fixes for const-correctness, now passes WARNS=3 on NetBSD. Pick up :ts modifier, allows controlling the separator used between words in variable expansion. 2003-07-11 Simon J. Gerraty * FILES: include boot-strap and os.sh * Makefile.in: only set WARNS if we are NetBSD, the effect on FreeBSD is known to be bad. * makefile.boot.in (bootstrap): make this the default target. * Makefile.in: bump version to 3.1.19 * machine.sh: avoid A-Z with tr as it is bound to lose. 2003-07-10 Simon J. Gerraty * Merge with NetBSD make Pick up fix for PR/19781 - unhelpful error msg on unclosed ${var:foo Plus some doc fixes. 2003-04-27 Simon J. Gerraty * Merge with NetBSD make Pick up fix for PR/1523 - don't count a library as built, if there is no way to build it * Bump version to 3.1.18 2003-03-23 Simon J. 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 Index: vendor/NetBSD/bmake/dist/Makefile =================================================================== --- vendor/NetBSD/bmake/dist/Makefile (revision 321026) +++ vendor/NetBSD/bmake/dist/Makefile (revision 321027) @@ -1,225 +1,225 @@ -# $Id: Makefile,v 1.92 2017/05/10 22:29:04 sjg Exp $ +# $Id: Makefile,v 1.94 2017/07/15 18:22:14 sjg Exp $ # Base version on src date -_MAKE_VERSION= 20170510 +_MAKE_VERSION= 20170711 PROG= bmake SRCS= \ arch.c \ buf.c \ compat.c \ cond.c \ dir.c \ for.c \ hash.c \ job.c \ main.c \ make.c \ make_malloc.c \ meta.c \ metachar.c \ parse.c \ str.c \ strlist.c \ suff.c \ targ.c \ trace.c \ util.c \ var.c # from lst.lib/ SRCS+= \ lstAppend.c \ lstAtEnd.c \ lstAtFront.c \ lstClose.c \ lstConcat.c \ lstDatum.c \ lstDeQueue.c \ lstDestroy.c \ lstDupl.c \ lstEnQueue.c \ lstFind.c \ lstFindFrom.c \ lstFirst.c \ lstForEach.c \ lstForEachFrom.c \ lstInit.c \ lstInsert.c \ lstIsAtEnd.c \ lstIsEmpty.c \ lstLast.c \ lstMember.c \ lstNext.c \ lstOpen.c \ lstPrev.c \ lstRemove.c \ lstReplace.c \ lstSucc.c # this file gets generated by configure .-include "Makefile.config" .if !empty(LIBOBJS) SRCS+= ${LIBOBJS:T:.o=.c} .endif # just in case prefix?= /usr srcdir?= ${.CURDIR} DEFAULT_SYS_PATH?= ${prefix}/share/mk CPPFLAGS+= -DUSE_META CFLAGS+= ${CPPFLAGS} CFLAGS+= -D_PATH_DEFSYSPATH=\"${DEFAULT_SYS_PATH}\" CFLAGS+= -I. -I${srcdir} ${XDEFS} -DMAKE_NATIVE CFLAGS+= ${COPTS.${.ALLSRC:M*.c:T:u}} COPTS.main.c+= "-DMAKE_VERSION=\"${_MAKE_VERSION}\"" # meta mode can be useful even without filemon FILEMON_H ?= /usr/include/dev/filemon/filemon.h .if exists(${FILEMON_H}) && ${FILEMON_H:T} == "filemon.h" COPTS.meta.c += -DHAVE_FILEMON_H -I${FILEMON_H:H} .endif .PATH: ${srcdir} .PATH: ${srcdir}/lst.lib .if make(obj) || make(clean) SUBDIR+= unit-tests .endif # start-delete1 for bsd.after-import.mk # we skip a lot of this when building as part of FreeBSD etc. # list of OS's which are derrived from BSD4.4 BSD44_LIST= NetBSD FreeBSD OpenBSD DragonFly MirBSD Bitrig # we are...

Its input is a list of specifications as to the files upon which programs and other files depend. If no .Fl f Ar makefile makefile option is given, .Nm will try to open .Ql Pa makefile then .Ql Pa Makefile in order to find the specifications. If the file .Ql 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" . .Pp .Nm will prepend the contents of the .Va 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 executing the commands to make 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 context. .It Fl d 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 .Va MAKEFLAGS environment variable and will be processed by any child make processes. By default, debugging information is printed to standard error, but this can be changed using the .Ar F debugging flag. The debugging output is always unbuffered; in addition, if debugging is enabled but debugging output is not directed to standard output, then the standard output is line buffered. .Ar Flags is one or more of the following: .Bl -tag -width Ds .It Ar A Print all possible debugging information; equivalent to specifying all of the debugging flags. .It Ar a Print debugging information about archive searching and caching. .It Ar C Print debugging information about current working directory. .It Ar c Print debugging information about conditional evaluation. .It Ar d Print debugging information about directory searching and caching. .It Ar e Print debugging information about failed commands and targets. .It Ar F Ns Oo Sy \&+ 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 .Ql F flag is .Ql \&+ , then the file will be opened in append mode; otherwise the file will be overwritten. If the file name is .Ql stdout or .Ql stderr then debugging output will be written to the standard output or standard error output file descriptors respectively (and the .Ql \&+ option has no effect). Otherwise, the output will be written to the named file. If the file name ends .Ql .%d then the .Ql %d is replaced by the pid. .It Ar f Print debugging information about loop evaluation. .It Ar "g1" Print the input graph before making anything. .It Ar "g2" Print the input graph after making everything, or before exiting on error. .It Ar "g3" Print the input graph before exiting on error. .It Ar j Print debugging information about running multiple shells. .It Ar l Print commands in Makefiles regardless of whether or not they are prefixed by .Ql @ or other "quiet" flags. Also known as "loud" behavior. .It Ar M Print debugging information about "meta" mode decisions about targets. .It Ar m Print debugging information about making targets, including modification dates. .It Ar 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 Ar p Print debugging information about makefile parsing. .It Ar s Print debugging information about suffix-transformation rules. .It Ar t Print debugging information about target list maintenance. .It Ar V Force the .Fl V -option to print raw values of variables. +option to print raw values of variables, overriding the default behavior +set via +.Va .MAKE.EXPAND_VARIABLES . .It Ar v Print debugging information about variable assignment. .It Ar x Run shell commands with .Fl x so the actual commands are printed as they are executed. .El .It Fl e Specify that environment variables override macro assignments within makefiles. .It Fl f Ar makefile Specify a makefile to read instead of the default .Ql Pa makefile . If .Ar makefile is .Ql Fl , 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 Fl 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 .Ar 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. The value is saved in .Va .MAKE.JOBS . Turns compatibility mode off, unless the .Ar B flag 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. .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 sys.mk and makefiles included via the .Ao Ar file Ac Ns -style include statement. The .Fl m option can be used multiple times to form a search path. This path will override the default system include path: /usr/share/mk. Furthermore the system include path will be appended to the search path used for .Qo Ar file Qc Ns -style include statements (see the .Fl I option). .Pp If a file or directory name in the .Fl m argument (or the .Ev MAKESYSPATH environment variable) starts with the string .Qq \&.../ then .Nm will search for the specified file or directory named in the remaining part of the argument string. The search starts with the current directory of the Makefile and then works upward towards the root of the file system. If the search is successful, then the resulting directory replaces the .Qq \&.../ specification in the .Fl m argument. If used, this feature allows .Nm to easily search in the current source tree for customized sys.mk files (e.g., by using .Qq \&.../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 .MAKE special source (see below). .It Fl N Display the commands which 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, but 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 Do not echo any commands as they are executed. Equivalent to specifying .Ql 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 -.Nm Ns 's -idea of the value of -.Ar variable , -in the global context. +Print the value of +.Ar variable . Do not build any targets. Multiple instances of this option may be specified; the variables will be printed one per line, with a blank line for each null or undefined variable. +The value printed is extracted from the global context after all +makefiles have been read. +By default, the raw variable contents (which may +include additional unexpanded variable references) are shown. If .Ar variable contains a .Ql \&$ -then the value will be expanded before printing. +then the value will be recursively expanded to its complete resultant +text before printing. +The expanded value will also be printed if +.Va .MAKE.EXPAND_VARIABLES +is set to true and +the +.Fl dV +option has not been used to override it. +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 the variable is always expanded to its complete value. .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 .Va MAKEFLAGS environment variable. This option may be useful on systems which have a small limit on the size of command arguments. .It Ar variable=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 seven different types of lines in a makefile: file dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, and comments. .Pp In general, 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 usually created from them. The exact relationship between the target and the source is determined by the operator that separates them. The three operators are as follows: .Bl -tag -width flag .It Ic \&: A target is considered out-of-date if its modification time is less than those of any of its sources. Sources for a target accumulate over dependency lines when this operator is used. The target is removed if .Nm is interrupted. .It Ic \&! Targets are always re-created, but not until all sources have been examined and re-created as necessary. Sources for a target accumulate over dependency lines when this operator is used. The target is removed if .Nm is interrupted. .It Ic \&:: If no sources are specified, the target is always re-created. Otherwise, a target is considered out-of-date if any of its sources has been modified more recently than the target. Sources for a target do not accumulate over dependency lines when this operator is used. The target will not be removed if .Nm is interrupted. .El .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 must be used to describe 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 appear in many dependency lines if desired, by default only one of these rules may be followed by a creation script. If the .Ql Ic \&:: operator is used, however, all rules may include scripts and the 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 .Pq Ql \e in which case that line and the next are combined. .\" The escaped newline is retained and passed to the shell, which .\" normally ignores it. .\" However, the tab at the beginning of the following line is removed. If the first characters of the command are any combination of .Ql Ic @ , .Ql Ic + , or .Ql Ic \- , the command is treated specially. A .Ql Ic @ causes the command not to be echoed before it is executed. A .Ql Ic + causes the command to be executed even when .Fl 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. A .Ql Ic \- in compatibility mode causes any non-zero exit status of the command line to be ignored. .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 will be passed to the shell; otherwise .Nm will attempt direct execution. If a line starts with .Ql Ic \- and the shell has ErrCtl enabled then failure of the command line will be ignored as in compatibility mode. Otherwise .Ql Ic \- affects the entire job; the script will stop at the first command line that fails, but the target will not be 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 needs to use .Dq cd or .Dq chdir without potentially changing the directory for subsequent commands should be put in parentheses so it executes in a subshell. To force the use of one 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} $@); \e echo Back in `pwd` .Ed .Pp Since .Nm will .Xr chdir 2 to .Ql Va .OBJDIR before executing any targets, each child process starts with that as its current working directory. .Sh VARIABLE ASSIGNMENTS Variables in make are much like variables in the shell, and, by tradition, consist of all upper-case letters. .Ss Variable assignment modifiers The five operators that can be used to assign values to variables are as follows: .Bl -tag -width Ds .It Ic \&= Assign the value to the variable. Any previous value is overridden. .It Ic \&+= Append the value to the current value of the variable. .It Ic \&?= Assign the value to the variable if it is not already defined. .It Ic \&:= Assign with expansion, i.e. expand the value before assigning it to the variable. Normally, expansion is not done until the variable is referenced. .Em NOTE : References to undefined variables are .Em not expanded. This can cause problems when variable modifiers are used. .It Ic \&!= Expand the value and pass it to the shell for execution and assign the result to the variable. Any newlines in the result are replaced with spaces. .El .Pp Any white-space before the assigned .Ar value is removed; if the value is being appended, a single space is inserted between the previous contents of the variable and the appended value. .Pp Variables are expanded by surrounding the variable name with either curly braces .Pq Ql {} or parentheses .Pq Ql () and preceding it with a dollar sign .Pq Ql \&$ . If the variable name contains only a single letter, the surrounding braces or parentheses are not required. This shorter form is not recommended. .Pp If the variable name contains a dollar, then the name itself is expanded first. This allows almost arbitrary variable names, however names containing dollar, braces, parenthesis, or whitespace are really best avoided! .Pp If the result of expanding a variable contains a dollar sign .Pq Ql \&$ the string is expanded again. .Pp Variable substitution occurs at three 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 shell commands are expanded when the shell command is executed. .It .Dq .for loop index variables are expanded on each loop iteration. Note that other variables are not expanded inside loops so the following example code: .Bd -literal -offset indent .Dv .for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} .Dv .endfor all: @echo ${a} @echo ${b} .Ed will print: .Bd -literal -offset indent 1 2 3 3 3 3 .Ed Because while ${a} contains .Dq 1 2 3 after the loop is executed, ${b} contains .Dq ${j} ${j} ${j} which expands to .Dq 3 3 3 since after the loop completes ${j} contains .Dq 3 . .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 are all built in and their values vary magically from target to target. It is not currently possible to define new local variables. The seven local variables are as follows: .Bl -tag -width ".ARCHIVE" -offset indent .It Va .ALLSRC The list of all sources for this target; also known as -.Ql Va \&\*[Gt] . +.Ql Va \&> . .It Va .ARCHIVE The name of the archive file; also known as .Ql 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 -.Ql Va \&\*[Lt] . +.Ql Va \&< . It is not defined in explicit rules. .It Va .MEMBER The name of the archive member; also known as .Ql Va % . .It Va .OODATE The list of sources for this target that were deemed out-of-date; also known as .Ql Va \&? . .It Va .PREFIX The file prefix of the target, containing only the file portion, no suffix or preceding directory components; also known as .Ql Va * . The suffix must be one of the known suffixes declared with .Ic .SUFFIXES or it will not be recognized. .It Va .TARGET The name of the target; also known as .Ql Va @ . For compatibility with other makes this is an alias for .Ic .ARCHIVE in archive member rules. .El .Pp The shorter forms -.Ql ( Va \*[Gt] , +.Ql ( Va > , .Ql Va \&! , -.Ql Va \*[Lt] , +.Ql Va < , .Ql Va % , .Ql Va \&? , .Ql Va * , and .Ql Va @ ) 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 Va $(@D) , are legacy forms equivalent to using the .Ql :H and .Ql :T modifiers. These forms are accepted for compatibility with .At V makefiles and POSIX but are not recommended. .Pp Four of the local variables may be used in sources on dependency lines because they expand to the proper value for each target on the line. These variables are .Ql Va .TARGET , .Ql Va .PREFIX , .Ql Va .ARCHIVE , and .Ql Va .MEMBER . .Ss Additional built-in variables In addition, .Nm sets or knows about the following variables: .Bl -tag -width .MAKEOVERRIDES .It Va \&$ A single dollar sign .Ql \&$ , i.e. .Ql \&$$ expands to a single dollar sign. .It Va .ALLTARGETS The list of all targets encountered in the Makefile. 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 .Ql Ev PWD for more details. .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. .It Ev MAKE The name that .Nm was executed with .Pq Va argv[0] . For compatibility .Nm also sets .Va .MAKE with the same value. The preferred variable to use is the environment variable .Ev MAKE because it is more compatible with other versions of .Nm and cannot be confused with the special target with the same name. .It Va .MAKE.DEPENDFILE Names the makefile (default .Ql Pa .depend ) from which generated dependencies are read. .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 .MAKE.JOBS The argument to the .Fl j option. .It Va .MAKE.JOB.PREFIX If .Nm is run with .Ar j then output for each target is prefixed with a token .Ql --- target --- the first part of which can be controlled via .Va .MAKE.JOB.PREFIX . If .Va .MAKE.JOB.PREFIX is empty, no token is printed. .br For example: .Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}] would produce tokens like .Ql ---make[1234] target --- making it easier to track the degree of parallelism being achieved. .It Ev MAKEFLAGS The environment variable .Ql 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 .Ql Ev MAKEFLAGS variable which is then entered into the environment for all programs which .Nm executes. .It Va .MAKE.LEVEL The recursion depth of .Nm . The initial instance of .Nm will be 0, and an incremented value is put into the environment to be seen by the next generation. This allows tests like: .Li .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the initial instance of .Nm . .It Va .MAKE.MAKEFILE_PREFERENCE The ordered list of makefile names (default .Ql Pa makefile , .Ql Pa Makefile ) that .Nm will look 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.MODE Processed after reading all makefiles. Can affect the mode that .Nm runs in. It can contain a number of keywords: .Bl -hang -width missing-filemon=bf. .It Pa compat Like .Fl B , puts .Nm into "compat" mode. .It Pa meta Puts .Nm into "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 very useful when diagnosing errors. .It Pa curdirOk= Ar bf Normally .Nm will not create .meta files in .Ql Va .CURDIR . This can be overridden by setting .Va bf to a value which represents True. .It Pa missing-meta= Ar bf If .Va bf is True, then a missing .meta file makes the target out-of-date. .It Pa missing-filemon= Ar bf If .Va bf is True, then missing filemon data makes the target out-of-date. .It Pa nofilemon Do not use .Xr filemon 4 . .It Pa env For debugging, it can be useful to include the environment in the .meta file. .It Pa 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 the value of: .Va .MAKE.META.PREFIX . .It Pa 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 .Ic .NOMETA_CMP . .It Pa silent= Ar bf If .Va bf is True, when a .meta file is created, mark the target .Ic .SILENT . .El .It Va .MAKE.META.BAILIWICK In "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.CREATED In "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 "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_PATHS Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: .Ql 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.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.PREFIX Defines the message printed for each meta file updated in "meta verbose" mode. The default value is: .Dl Building ${.TARGET:H:tA}/${.TARGET:T} .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 .Ql Ev MAKEFLAGS . This behavior can be disabled by assigning an empty value to .Ql Va .MAKEOVERRIDES within a makefile. Extra variables can be exported from a makefile by appending their names to .Ql Va .MAKEOVERRIDES . .Ql Ev MAKEFLAGS is re-exported whenever .Ql 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 Va .MAKE.PPID The parent process-id of .Nm . .It Va .MAKE.SAVE_DOLLARS value should be a boolean that controls whether .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_PRINT_VAR_ON_ERROR When .Nm stops due to an error, it sets .Ql Va .ERROR_TARGET to the name of the target that failed, .Ql Va .ERROR_CMD to the commands of the failed target, and in "meta" mode, it also sets .Ql Va .ERROR_CWD to the .Xr getcwd 3 , and .Ql 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 .Ql Va .CURDIR as well as the value of any variables named in .Ql Va MAKE_PRINT_VAR_ON_ERROR . .It Va .newline This variable is simply assigned a newline character as its value. This allows expansions using the .Cm \&:@ modifier to put a newline between iterations of the loop rather than a space. For example, the printing of .Ql Va MAKE_PRINT_VAR_ON_ERROR could be done as ${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 .Ev ${MAKEOBJDIRPREFIX}${.CURDIR} .Pp (Only if .Ql Ev MAKEOBJDIRPREFIX is set in the environment or on the command line.) .It .Ev ${MAKEOBJDIR} .Pp (Only if .Ql Ev MAKEOBJDIR is set in the environment or on the command line.) .It .Ev ${.CURDIR} Ns Pa /obj. Ns Ev ${MACHINE} .It .Ev ${.CURDIR} Ns Pa /obj .It .Pa /usr/obj/ Ns Ev ${.CURDIR} .It .Ev ${.CURDIR} .El .Pp Variable expansion is performed on the value before it's used, so expressions such as .Dl ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with .Ql Ev MAKEOBJDIR . .Pp .Ql Va .OBJDIR may be modified in the makefile via the special target .Ql Ic .OBJDIR . In all cases, .Nm will .Xr chdir 2 to the specified directory if it exists, and set .Ql Va .OBJDIR and .Ql Ev PWD to that directory before executing any targets. . .It Va .PARSEDIR A path to the directory of the current .Ql Pa Makefile being parsed. .It Va .PARSEFILE The basename of the current .Ql Pa Makefile being parsed. This variable and .Ql Va .PARSEDIR are both set only while the .Ql Pa Makefiles are being parsed. If you want to retain their current values, assign them to a variable using assignment with expansion: .Pq Ql Cm \&:= . .It Va .PATH A variable that represents the list of directories that .Nm will search for files. The search list should be updated using the target .Ql Va .PATH rather than the variable. .It Ev PWD Alternate path to the current directory. .Nm normally sets .Ql Va .CURDIR to the canonical path given by .Xr getcwd 3 . However, if the environment variable .Ql Ev PWD is set and gives a path to the current directory, then .Nm sets .Ql Va .CURDIR to the value of .Ql Ev PWD instead. This behavior is disabled if .Ql Ev MAKEOBJDIRPREFIX is set or .Ql Ev MAKEOBJDIR contains a variable transform. .Ql Ev PWD is set to the value of .Ql Va .OBJDIR for all programs which .Nm executes. .It Ev .TARGETS The list of targets explicitly specified on the command line, if any. .It Ev VPATH Colon-separated .Pq Dq \&: lists of directories that .Nm will search for files. The variable is supported for compatibility with old make programs only, use .Ql Va .PATH instead. .El .Ss Variable modifiers Variable expansion may be modified to select or modify each word of the variable (where a .Dq word is white-space delimited sequence of characters). The general format of a variable expansion is as follows: .Pp .Dl ${variable[:modifier[:...]]} .Pp Each modifier begins with a colon, which may be escaped with a backslash .Pq Ql \e . .Pp A set of modifiers can be specified via a variable, as follows: .Pp .Dl modifier_variable=modifier[:...] .Dl ${variable:${modifier_variable}[:...]} .Pp In this case the first modifier in the modifier_variable does not start with a colon, since that must appear in the referencing variable. If any of the modifiers in the modifier_variable contain a dollar sign .Pq Ql $ , these must be doubled to avoid early expansion. .Pp The supported modifiers are: .Bl -tag -width EEE .It Cm \&:E Replaces each word in the variable with its suffix. .It Cm \&:H Replaces each word in the variable with everything but the last component. .It Cm \&:M Ns Ar pattern Select only those words that match .Ar pattern . The standard shell wildcard characters .Pf ( Ql * , .Ql \&? , and .Ql Oo Oc ) 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, a construct like .Dl ${VAR:M*} will normalize the inter-word spacing, removing all leading and trailing space, and converting multiple consecutive spaces to single spaces. . .It Cm \&:N Ns Ar pattern This is identical to .Ql Cm \&:M , but selects all words which do not match .Ar pattern . .It Cm \&:O Order every word in variable alphabetically. To sort words in reverse order use the .Ql Cm \&:O:[-1..1] combination of modifiers. .It Cm \&:Ox Randomize words in variable. The results will be different each time you are referring to the modified variable; use the assignment with expansion .Pq Ql 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 variable, so that it can be passed safely through recursive invocations of .Nm . .It Cm \&:R Replaces each word in the variable with everything but its suffix. .It Cm \&:range[=count] The value is an integer sequence representing the words of the original value, or the supplied .Va count . .It Cm \&:gmtime[=utc] The value is a format string for .Xr strftime 3 , using .Xr gmtime 3 . If a .Va utc value is not provided or is 0, the current time is used. .It Cm \&:hash Compute a 32-bit hash of the value and encode it as hex digits. .It Cm \&:localtime[=utc] The value is a format string for .Xr strftime 3 , using .Xr localtime 3 . If a .Va utc value is not provided or is 0, the current time is used. .It Cm \&:tA Attempt to convert variable to an absolute path using .Xr realpath 3 , if that fails, the value is unchanged. .It Cm \&:tl Converts variable to lower-case letters. .It Cm \&:ts Ns Ar c Words in the variable are normally separated by a space on expansion. This modifier sets the separator to the character .Ar c . If .Ar c is omitted, then no separator is used. The common escapes (including octal numeric codes), work as expected. .It Cm \&:tu Converts variable to upper-case letters. .It Cm \&:tW Causes the value to be treated as a single word (possibly containing embedded white space). See also .Ql Cm \&:[*] . .It Cm \&:tw Causes the value to be treated as a sequence of words delimited by white space. See also .Ql Cm \&:[@] . .Sm off .It Cm \&:S No \&/ Ar old_string No \&/ Ar new_string No \&/ Op Cm 1gW .Sm on Modify the first occurrence of .Ar old_string in the variable's value, replacing it with .Ar new_string . If a .Ql g is appended to the last slash of the pattern, all occurrences in each word are replaced. If a .Ql 1 is appended to the last slash of the pattern, only the first word is affected. If a .Ql W is appended to the last slash of the pattern, then the value is treated as a single word (possibly containing embedded white space). 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 \*[Am] +.Pq Ql & is replaced by .Ar old_string (without any .Ql ^ or .Ql \&$ ) . Any character may be used as a delimiter for the parts of the modifier string. The anchoring, ampersand and delimiter characters may be escaped with a backslash .Pq Ql \e . .Pp Variable expansion occurs in the normal fashion inside both .Ar old_string and .Ar new_string with the single exception that a backslash is used to prevent the expansion of a dollar sign .Pq Ql \&$ , not a preceding dollar sign as is usual. .Sm off .It Cm \&:C No \&/ Ar pattern No \&/ Ar replacement No \&/ Op Cm 1gW .Sm on The .Cm \&:C modifier is just like the .Cm \&:S modifier except that the old and new strings, instead of being simple strings, are an extended regular expression (see .Xr regex 3 ) string .Ar pattern and an .Xr ed 1 Ns \-style string .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 white space). Note that .Ql 1 and .Ql g are orthogonal; the former specifies whether multiple words are potentially affected, the latter whether multiple substitutions can potentially occur within each affected word. .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 in the variable with its last component. .It Cm \&:u Remove 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 .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 itself - which will, of course, usually contain variable expansions. A common error is trying to use expressions like .Dl ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS), to determine is any words match "42" you need to use something like: .Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} . .It Ar :old_string=new_string This is the .At V style variable substitution. It must be the last modifier specified. If .Ar old_string or .Ar new_string do not contain the pattern matching character .Ar % then it is assumed that they are anchored at the end of each word, so only suffixes or entire words may be replaced. Otherwise .Ar % is the substring of .Ar old_string to be replaced in .Ar new_string . .Pp Variable expansion occurs in the normal fashion inside both .Ar old_string and .Ar new_string with the single exception that a backslash is used to prevent the expansion of a dollar sign .Pq Ql \&$ , not a preceding dollar sign as is usual. .Sm off .It Cm \&:@ Ar temp 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. Assign .Ar temp to each word in the variable and evaluate .Ar string . The ODE convention is that .Ar temp should start and end with a period. For example. .Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} .Pp However a single character variable is often more readable: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Cm \&:_[=var] Save the current variable value in .Ql $_ or the named .Va 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, then the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the rhs of a dependency. .Sm off .It Cm \&:\&! Ar cmd Cm \&! .Sm on The output of running .Ar cmd is the value. .It Cm \&:sh If the variable is non-empty it 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 when shell commands are being parsed. These assignment modifiers always expand to nothing, so if appearing in a rule line by themselves should be preceded with something to keep .Nm happy. .Pp The .Ql Cm \&:: helps avoid false matches with the .At V style .Cm \&:= modifier and since substitution always occurs the .Cm \&::= 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 divided into words. .Pp Ordinarily, a value is treated as a sequence of words delimited by white space. Some modifiers suppress this behavior, causing a value to be treated as a single word (possibly containing embedded white space). An empty value, or a value that consists entirely of white-space, is treated as a single word. For the purposes of the .Ql 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, .Ql Cm \&:[2..-1] selects all words from the second word to the last word. If .Ar start is greater than .Ar end , then the words are output in reverse order. For example, .Ql Cm \&:[-1..1] selects all the words from last to first. .\" :[*] .It Cm \&* Causes subsequent modifiers to treat the value as a single word (possibly containing embedded white space). Analogous to the effect of \&"$*\&" in Bourne shell. .\" :[0] .It 0 Means the same as .Ql Cm \&:[*] . .\" :[*] .It Cm \&@ Causes subsequent modifiers to treat the value as a sequence of words delimited by white space. Analogous to the effect of \&"$@\&" in Bourne shell. .\" :[#] .It Cm \&# Returns the number of words in the value. .El \" :[range] .El .Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS Makefile inclusion, conditional structures and for loops reminiscent of the C programming language are provided in .Nm . All such structures are identified by a line beginning with a single dot .Pq Ql \&. character. Files are included with either .Cm \&.include Aq Ar file or .Cm \&.include Pf \*q Ar file Ns \*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. For compatibility with other versions of .Nm .Ql include file ... is also accepted. .Pp If the include statement is written as .Cm .-include or as .Cm .sinclude then 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 will be ignored just like .Va .MAKE.DEPENDFILE . .Pp Conditional expressions are also preceded by a single dot as the first character of a line. The possible conditionals are as follows: .Bl -tag -width Ds .It Ic .error Ar message The message is printed along with the name of the makefile and line number, then .Nm will exit. .It Ic .export Ar variable ... 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 .Nm programs .Ql export variable=value is also accepted. .Pp Appending a variable name to .Va .MAKE.EXPORTED is equivalent to exporting a variable. .It Ic .export-env Ar variable ... 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 ... The same as .Ql .export-env , except that variables in the value are not expanded. .It Ic .info Ar message The message is printed along with the name of the makefile and line number. .It Ic .undef Ar variable Un-define the specified global variable. Only global variables may be un-defined. .It Ic .unexport Ar variable ... The opposite of .Ql .export . The specified global .Va variable will be 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 will cause 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 .Ql Ev PATH , which is the minimal useful environment. Actually .Ql Ev .MAKE.LEVEL will also be pushed into the new environment. .It Ic .warning Ar message The message prefixed by .Ql Pa warning: is printed along with the name of the makefile and line number. .It Ic \&.if Oo \&! Oc Ns Ar expression Op Ar operator expression ... Test the value of an expression. .It Ic .ifdef Oo \&! Oc Ns Ar variable Op Ar operator variable ... Test the value of a variable. .It Ic .ifndef Oo \&! Oc Ns Ar variable Op Ar operator variable ... Test the value of a variable. .It Ic .ifmake Oo \&! Oc Ns Ar target Op Ar operator target ...

A combination of .Ql Ic .else followed by .Ql 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 -width "Cm XX" .It Cm \&|\&| Logical OR. -.It Cm \&\*[Am]\*[Am] +.It Cm \&&& Logical .Tn AND ; of higher precedence than .Dq \&|\&| . .El .Pp As in C, .Nm will only evaluate a conditional as far as is necessary to determine its value. Parentheses may be used to change the order of evaluation. The boolean operator .Ql Ic \&! may be used to logically negate an entire conditional. It is of higher precedence than -.Ql Ic \&\*[Am]\*[Am] . +.Ql Ic \&&& . .Pp The value of .Ar expression may be any of the following: .Bl -tag -width defined .It Ic defined Takes a variable name as an argument and evaluates to true if the variable has been defined. .It Ic make Takes a target name as an argument and 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. .It Ic empty Takes a variable, with possible modifiers, and evaluates to true if the expansion of the variable would result in an empty string. .It Ic exists Takes a file name as an argument and evaluates to true if the file exists. The file is searched for on the system search path (see .Va .PATH ) . .It Ic target Takes a target name as an argument and evaluates to true if the target has been defined. .It Ic commands Takes a target name as an argument and 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, after which the integral values are compared. A value is interpreted as hexadecimal if it is preceded by 0x, otherwise it is decimal; octal numbers are not supported. The standard C relational operators are all supported. If after variable expansion, either the left or right hand side of a .Ql Ic == or .Ql Ic "!=" operator is not an integral value, then string comparison is performed between the expanded variables. If no relational operator is given, it is assumed that the expanded variable is being compared against 0 or an empty string in the case of a string comparison. .Pp When .Nm is evaluating one of these conditional expressions, and it encounters a (white-space separated) word it doesn't recognize, either the .Dq make or .Dq defined expression is applied to it, depending on the form of the conditional. If the form is .Ql Ic .ifdef , .Ql Ic .ifndef , or .Ql Ic .if the .Dq defined expression is applied. Similarly, if the form is .Ql Ic .ifmake or .Ql Ic .ifnmake , the .Dq make expression is applied. .Pp If the conditional evaluates to true the parsing of the makefile continues as before. If it evaluates to false, the following lines are skipped. In both cases this continues until a .Ql Ic .else or .Ql Ic .endif is found. .Pp 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 ... Oc Ic in Ar expression .It Aq make-rules .It Ic \&.endfor .El .Pp After the for .Ic expression is evaluated, it is split into words. On each iteration of the loop, one word is taken and assigned to each .Ic variable , in order, and these .Ic variables are substituted into the .Ic make-rules 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. .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 "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 will still be 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 will be compared @echo this will not ${.OODATE:M.NOMETA_CMP} @echo this will also be 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 .Ic .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 will ignore this fact and assume 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 will not be 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 Exactly like .Ic .USE , but 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 . .br 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 .Ic .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. .It Ic .ERROR Any command lines attached to this target are executed when another target fails. The .Ic .ERROR_TARGET variable is set to the target that failed. See also .Ic 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 will be executed. .It Ic .MAIN If no target is specified when .Nm is invoked, this target will be built. .It Ic .MAKEFLAGS This target provides a way to specify flags for .Nm when the makefile is used. The flags are as if typed to the shell, though the .Fl f option will have no effect. .\" XXX: NOT YET!!!! .\" .It Ic .NOTPARALLEL .\" The named targets are executed in non parallel mode. .\" If no targets are .\" specified, then 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 .OBJDIR The source is a new value for .Ql Va .OBJDIR . If it exists, .Nm will .Xr chdir 2 to it and update the value of .Ql Va .OBJDIR . .It Ic .ORDER 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 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 The ordering imposed by .Ic .ORDER is only relevant for parallel makes. .\" XXX: NOT YET!!!! .\" .It Ic .PARALLEL .\" The named targets are executed in parallel mode. .\" If no targets are .\" specified, then 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 deleted. If the source is the special .Ic .DOTLAST target, then the current working directory is searched last. .It Ic .PATH. Ns Va 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 .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 .SHELL Sets the shell that .Nm will use to execute commands. The sources are a set of .Ar field=value pairs. .Bl -tag -width hasErrCtls .It Ar name This is the minimal specification, used to select one of the built-in shell specs; .Ar sh , .Ar ksh , and .Ar csh . .It Ar path Specifies the path to the shell. .It Ar hasErrCtl Indicates whether the shell supports exit on error. .It Ar check The command to turn on error checking. .It Ar ignore The command to disable error checking. .It Ar echo The command to turn on echoing of commands executed. .It Ar quiet The command to turn off echoing of commands executed. .It Ar filter The output to filter after issuing the .Ar quiet command. It is typically identical to .Ar quiet . .It Ar errFlag The flag to pass the shell to enable error checking. .It Ar echoFlag The flag to pass the shell to enable command echoing. .It Ar 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: .o \&.c.o: cc \-o ${.TARGET} \-c ${.IMPSRC} .Ed .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 .Ql Va .OBJDIR for more details. .Sh FILES .Bl -tag -width /usr/share/mk -compact .It .depend list of dependencies .It Makefile list of dependencies .It makefile list of dependencies .It sys.mk system makefile .It /usr/share/mk system makefile directory .El .Sh COMPATIBILITY The basic make syntax is compatible between different versions of make; 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 these 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.) .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 .Dl :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 .Ic .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 .Dq FRC has been used to FoRCe rebuilding (since the target/dependency does not exist... unless someone creates an .Dq FRC file). .Sh BUGS The make syntax is difficult to parse without actually acting of the data. For instance finding the end of a variable use should involve scanning each 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.

The debugging output is always unbuffered; in addition, if debugging is enabled but debugging output is not directed to standard output, then the standard out- put is line buffered. _F_l_a_g_s is one or more of the following: _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 current working direc- tory. _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[++]_f_i_l_e_n_a_m_e 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 `+', then the file will be opened in append mode; otherwise the file will be overwritten. If the file name is `stdout' or `stderr' then debugging output will be written to the standard output or standard error output file descriptors respectively (and the `+' option has no effect). Otherwise, the output will be written to the named file. If the file name ends `.%d' then the `%d' is replaced by the pid. _f Print debugging information about loop evaluation. _g_1 Print the input graph before making anything. _g_2 Print the input graph after making everything, or before exiting on error. _g_3 Print the input graph before exiting on error. _j Print debugging information about running multiple shells. _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 _/_t_m_p if TMPDIR is unset or set to the empty string. The temporary scripts are created by mkstemp(3), and have names of the form _m_a_k_e_X_X_X_X_X_X. _N_O_T_E: This can create many files in TMPDIR or _/_t_m_p, 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 --VV option to print raw values of variables. + _V Force the --VV option to print raw values of variables, + overriding the default behavior set via + _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S. _v Print debugging information about variable assignment. _x Run shell commands with --xx so the actual commands are printed as they are executed. --ee Specify that environment variables override macro assignments within makefiles. --ff _m_a_k_e_f_i_l_e Specify a makefile to read instead of the default `_m_a_k_e_f_i_l_e'. If _m_a_k_e_f_i_l_e is `--', standard input is read. Multiple makefiles may be specified, and are read in the order specified. --II _d_i_r_e_c_t_o_r_y Specify a directory in which to search for makefiles and included makefiles. The system makefile directory (or directories, see the --mm option) is automatically included as part of this list. --ii Ignore non-zero exit of shell commands in the makefile. Equiva- lent to specifying `--' before each command line in the makefile. --JJ _p_r_i_v_a_t_e This option should _n_o_t 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. --jj _m_a_x___j_o_b_s Specify the maximum number of jobs that bbmmaakkee may have running at any one time. The value is saved in _._M_A_K_E_._J_O_B_S. Turns compati- bility mode off, unless the _B flag is also specified. When com- patibility mode is off, all commands associated with a target are executed in a single shell invocation as opposed to the tradi- tional 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. --kk Continue processing after errors are encountered, but only on those targets that do not depend on the target whose creation caused the error. --mm _d_i_r_e_c_t_o_r_y Specify a directory in which to search for sys.mk and makefiles included via the <_f_i_l_e>-style include statement. The --mm option can be used multiple times to form a search path. This path will override the default system include path: /usr/share/mk. Fur- thermore the system include path will be appended to the search path used for "_f_i_l_e"-style include statements (see the --II option). If a file or directory name in the --mm argument (or the MAKESYSPATH environment variable) starts with the string ".../" then bbmmaakkee will search for the specified file or directory named in the remaining part of the argument string. The search starts with the current directory of the Makefile and then works upward towards the root of the file system. If the search is success- ful, then the resulting directory replaces the ".../" specifica- tion in the --mm argument. If used, this feature allows bbmmaakkee to easily search in the current source tree for customized sys.mk files (e.g., by using ".../mk/sys.mk" as an argument). --nn 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). --NN Display the commands which would have been executed, but do not actually execute any of them; useful for debugging top-level makefiles without descending into subdirectories. --qq Do not execute any commands, but exit 0 if the specified targets are up-to-date and 1, otherwise. --rr Do not use the built-in rules specified in the system makefile. --ss Do not echo any commands as they are executed. Equivalent to specifying `@@' before each command line in the makefile. --TT _t_r_a_c_e_f_i_l_e When used with the --jj flag, append a trace record to _t_r_a_c_e_f_i_l_e for each job started and completed. --tt 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. --VV _v_a_r_i_a_b_l_e - Print bbmmaakkee's idea of the value of _v_a_r_i_a_b_l_e, in the global con- - text. Do not build any targets. Multiple instances of this - option may be specified; the variables will be printed one per - line, with a blank line for each null or undefined variable. If - _v_a_r_i_a_b_l_e contains a `$' then the value will be expanded before - printing. + Print the value of _v_a_r_i_a_b_l_e. Do not build any targets. Multiple + instances of this option may be specified; the variables will be + printed one per line, with a blank line for each null or unde- + fined variable. The value printed is extracted from the global + context after all makefiles have been read. By default, the raw + variable contents (which may include additional unexpanded vari- + able references) are shown. If _v_a_r_i_a_b_l_e contains a `$' then the + value will be recursively expanded to its complete resultant text + before printing. The expanded value will also be printed if + _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S is set to true and the --ddVV option has not + been used to override it. Note that loop-local and target-local + variables, as well as values taken temporarily by global vari- + ables during makefile processing, are not accessible via this + option. The --ddvv debug mode can be used to see these at the cost + of generating substantial extraneous output. + --vv _v_a_r_i_a_b_l_e + Like --VV but the variable is always expanded to its complete + value. + --WW Treat any warnings during makefile parsing as errors. --ww Print entering and leaving directory messages, pre and post pro- cessing. --XX 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 _M_A_K_E_F_L_A_G_S environment variable. This option may be useful on systems which have a small limit on the size of command arguments. _v_a_r_i_a_b_l_e_=_v_a_l_u_e Set the value of the variable _v_a_r_i_a_b_l_e to _v_a_l_u_e. Normally, all values passed on the command line are also exported to sub-makes in the environment. The --XX flag disables this behavior. Vari- able assignments should follow options for POSIX compatibility but no ordering is enforced. There are seven different types of lines in a makefile: file dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, and comments. In general, 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. FFIILLEE DDEEPPEENNDDEENNCCYY SSPPEECCIIFFIICCAATTIIOONNSS 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 usually created from them. The exact relationship between the target and the source is determined by the operator that sep- arates them. The three operators are as follows: :: A target is considered out-of-date if its modification time is less than those of any of its sources. Sources for a target accumulate over dependency lines when this operator is used. The target is removed if bbmmaakkee is interrupted. !! Targets are always re-created, but not until all sources have been examined and re-created as necessary. Sources for a target accumu- late over dependency lines when this operator is used. The target is removed if bbmmaakkee is interrupted. :::: If no sources are specified, the target is always re-created. Oth- erwise, a target is considered out-of-date if any of its sources has been modified more recently than the target. Sources for a target do not accumulate over dependency lines when this operator is used. The target will not be removed if bbmmaakkee is interrupted. 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 must be used to describe 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. SSHHEELLLL CCOOMMMMAANNDDSS 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 _m_u_s_t be preceded by a tab. (For historical reasons, spaces are not accepted.) While targets can appear in many dependency lines if desired, 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 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. A `@@' causes the command not to be echoed before it is executed. A `++' causes the command to be executed even when --nn is given. This is similar to the effect of the .MAKE special source, except that the effect can be limited to a sin- gle line of a script. A `--' in compatibility mode causes any non-zero exit status of the command line to be ignored. When bbmmaakkee is run in jobs mode with --jj _m_a_x___j_o_b_s, 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 will be passed to the shell; otherwise bbmmaakkee will attempt direct execu- tion. If a line starts with `--' and the shell has ErrCtl enabled then failure of the command line will be ignored as in compatibility mode. Otherwise `--' affects the entire job; the script will stop at the first command line that fails, but the target will not be deemed to have failed. Makefiles should be written so that the mode of bbmmaakkee operation does not change their behavior. For example, any command which needs to use ``cd'' or ``chdir'' without potentially changing the directory for subse- quent commands should be put in parentheses so it executes in a subshell. To force the use of one 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} $@); \ echo Back in `pwd` Since bbmmaakkee will chdir(2) to `_._O_B_J_D_I_R' before executing any targets, each child process starts with that as its current working directory. VVAARRIIAABBLLEE AASSSSIIGGNNMMEENNTTSS Variables in make are much like variables in the shell, and, by tradi- tion, consist of all upper-case letters. VVaarriiaabbllee aassssiiggnnmmeenntt mmooddiiffiieerrss The five operators that can be used to assign values to variables are as follows: == Assign the value to the variable. Any previous value is overrid- den. ++== Append the value to the current value of the variable. ??== Assign the value to the variable if it is not already defined. ::== Assign with expansion, i.e. expand the value before assigning it to the variable. Normally, expansion is not done until the vari- able is referenced. _N_O_T_E: References to undefined variables are _n_o_t expanded. This can cause problems when variable modifiers are used. !!== Expand the value and pass it to the shell for execution and assign the result to the variable. Any newlines in the result are replaced with spaces. Any white-space before the assigned _v_a_l_u_e is removed; if the value is being appended, a single space is inserted between the previous contents of the variable and the appended value. Variables are expanded by surrounding the variable name with either curly braces (`{}') or parentheses (`()') and preceding it with a dollar sign (`$'). If the variable name contains only a single letter, the surround- ing braces or parentheses are not required. This shorter form is not recommended. If the variable name contains a dollar, then the name itself is expanded first. This allows almost arbitrary variable names, however names con- taining dollar, braces, parenthesis, or whitespace are really best avoided! If the result of expanding a variable contains a dollar sign (`$') the string is expanded again. Variable substitution occurs at three 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 shell commands are expanded when the shell command is executed. 3. ``.for'' loop index variables are expanded on each loop iteration. Note that other variables are not expanded inside loops so the fol- lowing example code: .for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} .endfor all: @echo ${a} @echo ${b} will print: 1 2 3 3 3 3 Because while ${a} contains ``1 2 3'' after the loop is executed, ${b} contains ``${j} ${j} ${j}'' which expands to ``3 3 3'' since after the loop completes ${j} contains ``3''. VVaarriiaabbllee ccllaasssseess The four different classes of variables (in order of increasing prece- dence) are: Environment variables Variables defined as part of bbmmaakkee's environment. Global variables Variables defined in the makefile or in included makefiles. Command line variables Variables defined as part of the command line. Local variables Variables that are defined specific to a certain target. Local variables are all built in and their values vary magically from target to target. It is not currently possible to define new local vari- ables. The seven local variables are as follows: _._A_L_L_S_R_C The list of all sources for this target; also known as `_>'. _._A_R_C_H_I_V_E The name of the archive file; also known as `_!'. _._I_M_P_S_R_C In suffix-transformation rules, the name/path of the source from which the target is to be transformed (the ``implied'' source); also known as `_<'. It is not defined in explicit rules. _._M_E_M_B_E_R The name of the archive member; also known as `_%'. _._O_O_D_A_T_E The list of sources for this target that were deemed out- of-date; also known as `_?'. _._P_R_E_F_I_X The file prefix of the target, containing only the file portion, no suffix or preceding directory components; also known as `_*'. The suffix must be one of the known suffixes declared with ..SSUUFFFFIIXXEESS or it will not be recog- nized. _._T_A_R_G_E_T The name of the target; also known as `_@'. For compati- bility with other makes this is an alias for ..AARRCCHHIIVVEE in archive member rules. The shorter forms (`_>', `_!', `_<', `_%', `_?', `_*', and `_@') are permitted for backward compatibility with historical makefiles and legacy POSIX make and are not recommended. Variants of these variables with the punctuation followed immediately by `D' or `F', e.g. `_$_(_@_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 `_._T_A_R_G_E_T', `_._P_R_E_F_I_X', `_._A_R_C_H_I_V_E', and `_._M_E_M_B_E_R'. AAddddiittiioonnaall bbuuiilltt--iinn vvaarriiaabblleess In addition, bbmmaakkee sets or knows about the following variables: _$ A single dollar sign `$', i.e. `$$' expands to a single dollar sign. _._A_L_L_T_A_R_G_E_T_S The list of all targets encountered in the Makefile. If evaluated during Makefile parsing, lists only those tar- gets encountered thus far. _._C_U_R_D_I_R A path to the directory where bbmmaakkee was executed. Refer to the description of `PWD' for more details. _._I_N_C_L_U_D_E_D_F_R_O_M_D_I_R The directory of the file this Makefile was included from. _._I_N_C_L_U_D_E_D_F_R_O_M_F_I_L_E The filename of the file this Makefile was included from. MAKE The name that bbmmaakkee was executed with (_a_r_g_v_[_0_]). For compatibility bbmmaakkee also sets _._M_A_K_E with the same value. The preferred variable to use is the environment variable MAKE because it is more compatible with other versions of bbmmaakkee and cannot be confused with the special target with the same name. _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E Names the makefile (default `_._d_e_p_e_n_d') from which gener- ated dependencies are read. _._M_A_K_E_._E_X_P_A_N_D___V_A_R_I_A_B_L_E_S A boolean that controls the default behavior of the --VV - option. + option. If true, variable values printed with --VV are + fully expanded; if false, the raw variable contents + (which may include additional unexpanded variable refer- + ences) are shown. _._M_A_K_E_._E_X_P_O_R_T_E_D The list of variables exported by bbmmaakkee. _._M_A_K_E_._J_O_B_S The argument to the --jj option. _._M_A_K_E_._J_O_B_._P_R_E_F_I_X If bbmmaakkee is run with _j then output for each target is prefixed with a token `--- target ---' the first part of which can be controlled via _._M_A_K_E_._J_O_B_._P_R_E_F_I_X. If _._M_A_K_E_._J_O_B_._P_R_E_F_I_X is empty, no token is printed. For example: .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}] would produce tokens like `---make[1234] target ---' mak- ing it easier to track the degree of parallelism being achieved. MAKEFLAGS The environment variable `MAKEFLAGS' may contain anything that may be specified on bbmmaakkee's command line. Anything specified on bbmmaakkee's command line is appended to the `MAKEFLAGS' variable which is then entered into the envi- ronment for all programs which bbmmaakkee executes. _._M_A_K_E_._L_E_V_E_L The recursion depth of bbmmaakkee. The initial instance of bbmmaakkee will be 0, and an incremented value is put into the environment to be seen by the next generation. This allows tests like: .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the initial instance of bbmmaakkee. _._M_A_K_E_._M_A_K_E_F_I_L_E___P_R_E_F_E_R_E_N_C_E The ordered list of makefile names (default `_m_a_k_e_f_i_l_e', `_M_a_k_e_f_i_l_e') that bbmmaakkee will look for. _._M_A_K_E_._M_A_K_E_F_I_L_E_S The list of makefiles read by bbmmaakkee, which is useful for tracking dependencies. Each makefile is recorded only once, regardless of the number of times read. _._M_A_K_E_._M_O_D_E Processed after reading all makefiles. Can affect the mode that bbmmaakkee runs in. It can contain a number of key- words: _c_o_m_p_a_t Like --BB, puts bbmmaakkee into "compat" mode. _m_e_t_a Puts bbmmaakkee into "meta" mode, where meta files are created for each tar- get to capture the command run, the output generated and if filemon(4) is available, the system calls which are of interest to bbmmaakkee. The cap- tured output can be very useful when diagnosing errors. _c_u_r_d_i_r_O_k_= _b_f Normally bbmmaakkee will not create .meta files in `_._C_U_R_D_I_R'. This can be overridden by setting _b_f to a value which represents True. _m_i_s_s_i_n_g_-_m_e_t_a_= _b_f If _b_f is True, then a missing .meta file makes the target out-of-date. _m_i_s_s_i_n_g_-_f_i_l_e_m_o_n_= _b_f If _b_f is True, then missing filemon data makes the target out-of-date. _n_o_f_i_l_e_m_o_n Do not use filemon(4). _e_n_v For debugging, it can be useful to include the environment in the .meta file. _v_e_r_b_o_s_e 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 the value of: _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X. _i_g_n_o_r_e_-_c_m_d Some makefiles have commands which are simply not stable. This keyword causes them to be ignored for deter- mining whether a target is out of date in "meta" mode. See also ..NNOOMMEETTAA__CCMMPP. _s_i_l_e_n_t_= _b_f If _b_f is True, when a .meta file is created, mark the target ..SSIILLEENNTT. _._M_A_K_E_._M_E_T_A_._B_A_I_L_I_W_I_C_K In "meta" mode, provides a list of prefixes which match the directories controlled by bbmmaakkee. If a file that was generated outside of _._O_B_J_D_I_R but within said bailiwick is missing, the current target is considered out-of-date. _._M_A_K_E_._M_E_T_A_._C_R_E_A_T_E_D In "meta" mode, this variable contains a list of all the meta files updated. If not empty, it can be used to trigger processing of _._M_A_K_E_._M_E_T_A_._F_I_L_E_S. _._M_A_K_E_._M_E_T_A_._F_I_L_E_S 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 informa- tion. _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___P_A_T_H_S Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: `_/_d_e_v _/_e_t_c _/_p_r_o_c _/_t_m_p _/_v_a_r_/_r_u_n _/_v_a_r_/_t_m_p' _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___P_A_T_T_E_R_N_S Provides a list of patterns to match against pathnames. Ignore any that match. _._M_A_K_E_._M_E_T_A_._I_G_N_O_R_E___F_I_L_T_E_R Provides a list of variable modifiers to apply to each pathname. Ignore if the expansion is an empty string. _._M_A_K_E_._M_E_T_A_._P_R_E_F_I_X Defines the message printed for each meta file updated in "meta verbose" mode. The default value is: Building ${.TARGET:H:tA}/${.TARGET:T} _._M_A_K_E_O_V_E_R_R_I_D_E_S 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 `_._M_A_K_E_O_V_E_R_R_I_D_E_S' within a makefile. Extra variables can be exported from a makefile by appending their names to `_._M_A_K_E_O_V_E_R_R_I_D_E_S'. `MAKEFLAGS' is re-exported whenever `_._M_A_K_E_O_V_E_R_R_I_D_E_S' is modified. _._M_A_K_E_._P_A_T_H___F_I_L_E_M_O_N If bbmmaakkee was built with filemon(4) support, this is set to the path of the device node. This allows makefiles to test for this support. _._M_A_K_E_._P_I_D The process-id of bbmmaakkee. _._M_A_K_E_._P_P_I_D The parent process-id of bbmmaakkee. _._M_A_K_E_._S_A_V_E___D_O_L_L_A_R_S value should be a boolean that controls whether `$$' are preserved when doing `:=' assignments. The default is false, for backwards compatibility. Set to true for com- patability with other makes. If set to false, `$$' becomes `$' per normal evaluation rules. _M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R When bbmmaakkee stops due to an error, it sets `_._E_R_R_O_R___T_A_R_G_E_T' to the name of the target that failed, `_._E_R_R_O_R___C_M_D' to the commands of the failed target, and in "meta" mode, it also sets `_._E_R_R_O_R___C_W_D' to the getcwd(3), and `_._E_R_R_O_R___M_E_T_A___F_I_L_E' to the path of the meta file (if any) describing the failed target. It then prints its name and the value of `_._C_U_R_D_I_R' as well as the value of any variables named in `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R'. _._n_e_w_l_i_n_e This variable is simply assigned a newline character as its value. This allows expansions using the ::@@ modifier to put a newline between iterations of the loop rather than a space. For example, the printing of `_M_A_K_E___P_R_I_N_T___V_A_R___O_N___E_R_R_O_R' could be done as ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@}. _._O_B_J_D_I_R A path to the directory where the targets are built. Its value is determined by trying to chdir(2) to the follow- ing directories in order and using the first match: 1. ${MAKEOBJDIRPREFIX}${.CURDIR} (Only if `MAKEOBJDIRPREFIX' is set in the environ- ment or on the command line.) 2. ${MAKEOBJDIR} (Only if `MAKEOBJDIR' is set in the environment or on the command line.) 3. ${.CURDIR}_/_o_b_j_.${MACHINE} 4. ${.CURDIR}_/_o_b_j 5. _/_u_s_r_/_o_b_j_/${.CURDIR} 6. ${.CURDIR} Variable expansion is performed on the value before it's used, so expressions such as ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with `MAKEOBJDIR'. `_._O_B_J_D_I_R' may be modified in the makefile via the special target `..OOBBJJDDIIRR'. In all cases, bbmmaakkee will chdir(2) to the specified directory if it exists, and set `_._O_B_J_D_I_R' and `PWD' to that directory before executing any targets. _._P_A_R_S_E_D_I_R A path to the directory of the current `_M_a_k_e_f_i_l_e' being parsed. _._P_A_R_S_E_F_I_L_E The basename of the current `_M_a_k_e_f_i_l_e' being parsed. This variable and `_._P_A_R_S_E_D_I_R' are both set only while the `_M_a_k_e_f_i_l_e_s' are being parsed. If you want to retain their current values, assign them to a variable using assignment with expansion: (`::=='). _._P_A_T_H A variable that represents the list of directories that bbmmaakkee will search for files. The search list should be updated using the target `_._P_A_T_H' rather than the vari- able. PWD Alternate path to the current directory. bbmmaakkee normally sets `_._C_U_R_D_I_R' to the canonical path given by getcwd(3). However, if the environment variable `PWD' is set and gives a path to the current directory, then bbmmaakkee sets `_._C_U_R_D_I_R' to the value of `PWD' instead. This behavior is disabled if `MAKEOBJDIRPREFIX' is set or `MAKEOBJDIR' contains a variable transform. `PWD' is set to the value of `_._O_B_J_D_I_R' for all programs which bbmmaakkee executes. .TARGETS The list of targets explicitly specified on the command line, if any. VPATH Colon-separated (``:'') lists of directories that bbmmaakkee will search for files. The variable is supported for compatibility with old make programs only, use `_._P_A_T_H' instead. VVaarriiaabbllee mmooddiiffiieerrss Variable expansion may be modified to select or modify each word of the variable (where a ``word'' is white-space delimited sequence of charac- ters). The general format of a variable expansion is as follows: ${variable[:modifier[:...]]} Each modifier begins with a colon, which may be escaped with a backslash (`\'). A set of 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 must appear in the referencing variable. If any of the modifiers in the modifier_variable contain a dollar sign (`$'), these must be doubled to avoid early expansion. The supported modifiers are: ::EE Replaces each word in the variable with its suffix. ::HH Replaces each word in the variable with everything but the last com- ponent. ::MM_p_a_t_t_e_r_n Select only those words that match _p_a_t_t_e_r_n. 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, a construct like ${VAR:M*} will normalize the inter-word spacing, removing all leading and trailing space, and converting multiple consecutive spaces to single spaces. ::NN_p_a_t_t_e_r_n This is identical to `::MM', but selects all words which do not match _p_a_t_t_e_r_n. ::OO Order every word in variable alphabetically. To sort words in reverse order use the `::OO::[[--11....11]]' combination of modifiers. ::OOxx Randomize words in variable. The results will be different each time you are referring 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 ::QQ Quotes every shell meta-character in the variable, so that it can be passed safely through recursive invocations of bbmmaakkee. ::RR Replaces each word in the variable with everything but its suffix. ::rraannggee[[==ccoouunntt]] The value is an integer sequence representing the words of the orig- inal value, or the supplied _c_o_u_n_t. ::ggmmttiimmee[[==uuttcc]] The value is a format string for strftime(3), using gmtime(3). If a _u_t_c value is not provided or is 0, the current time is used. ::hhaasshh Compute a 32-bit hash of the value and encode it as hex digits. ::llooccaallttiimmee[[==uuttcc]] The value is a format string for strftime(3), using localtime(3). If a _u_t_c value is not provided or is 0, the current time is used. ::ttAA Attempt to convert variable to an absolute path using realpath(3), if that fails, the value is unchanged. ::ttll Converts variable to lower-case letters. ::ttss_c Words in the variable are normally separated by a space on expan- sion. This modifier sets the separator to the character _c. If _c is omitted, then no separator is used. The common escapes (including octal numeric codes), work as expected. ::ttuu Converts variable to upper-case letters. ::ttWW Causes the value to be treated as a single word (possibly containing embedded white space). See also `::[[**]]'. ::ttww Causes the value to be treated as a sequence of words delimited by white space. See also `::[[@@]]'. ::SS/_o_l_d___s_t_r_i_n_g/_n_e_w___s_t_r_i_n_g/[11ggWW] Modify the first occurrence of _o_l_d___s_t_r_i_n_g in the variable's value, replacing it with _n_e_w___s_t_r_i_n_g. If a `g' is appended to the last slash of the pattern, all occurrences in each word are replaced. If a `1' is appended to the last slash of the pattern, only the first word is affected. If a `W' is appended to the last slash of the pattern, then the value is treated as a single word (possibly con- taining embedded white space). If _o_l_d___s_t_r_i_n_g begins with a caret (`^'), _o_l_d___s_t_r_i_n_g is anchored at the beginning of each word. If _o_l_d___s_t_r_i_n_g ends with a dollar sign (`$'), it is anchored at the end of each word. Inside _n_e_w___s_t_r_i_n_g, an ampersand (`&') is replaced by _o_l_d___s_t_r_i_n_g (without any `^' or `$'). Any character may be used as a delimiter for the parts of the modifier string. The anchoring, ampersand and delimiter characters may be escaped with a backslash (`\'). Variable expansion occurs in the normal fashion inside both _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash is used to prevent the expansion of a dollar sign (`$'), not a pre- ceding dollar sign as is usual. ::CC/_p_a_t_t_e_r_n/_r_e_p_l_a_c_e_m_e_n_t/[11ggWW] The ::CC modifier is just like the ::SS modifier except that the old and new strings, instead of being simple strings, are an extended regu- lar expression (see regex(3)) string _p_a_t_t_e_r_n and an ed(1)-style string _r_e_p_l_a_c_e_m_e_n_t. Normally, the first occurrence of the pattern _p_a_t_t_e_r_n in each word of the value is substituted with _r_e_p_l_a_c_e_m_e_n_t. 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 _p_a_t_t_e_r_n as occur in the word or words it is found in; the `W' modifier causes the value to be treated as a single word (possibly containing embedded white space). Note that `1' and `g' are orthogonal; the former specifies whether multiple words are potentially affected, the latter whether multiple substitutions can potentially occur within each affected word. As for the ::SS modifier, the _p_a_t_t_e_r_n and _r_e_p_l_a_c_e_m_e_n_t are subjected to variable expansion before being parsed as regular expressions. ::TT Replaces each word in the variable with its last component. ::uu Remove adjacent duplicate words (like uniq(1)). ::??_t_r_u_e___s_t_r_i_n_g::_f_a_l_s_e___s_t_r_i_n_g If the variable name (not its value), when parsed as a .if condi- tional expression, evaluates to true, return as its value the _t_r_u_e___s_t_r_i_n_g, otherwise return the _f_a_l_s_e___s_t_r_i_n_g. Since the variable name is used as the expression, :? must be the first modifier after the variable name itself - which will, of course, usually contain variable expansions. A common error is trying to use expressions like ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS), to determine is any words match "42" you need to use something like: ${"${NUMBERS:M42}" != "":?match:no}. _:_o_l_d___s_t_r_i_n_g_=_n_e_w___s_t_r_i_n_g This is the AT&T System V UNIX style variable substitution. It must be the last modifier specified. If _o_l_d___s_t_r_i_n_g or _n_e_w___s_t_r_i_n_g do not contain the pattern matching character _% then it is assumed that they are anchored at the end of each word, so only suffixes or entire words may be replaced. Otherwise _% is the substring of _o_l_d___s_t_r_i_n_g to be replaced in _n_e_w___s_t_r_i_n_g. Variable expansion occurs in the normal fashion inside both _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g with the single exception that a backslash is used to prevent the expansion of a dollar sign (`$'), not a pre- ceding dollar sign as is usual. ::@@_t_e_m_p@@_s_t_r_i_n_g@@ This is the loop expansion mechanism from the OSF Development Envi- ronment (ODE) make. Unlike ..ffoorr loops expansion occurs at the time of reference. Assign _t_e_m_p to each word in the variable and evaluate _s_t_r_i_n_g. The ODE convention is that _t_e_m_p should start and end with a period. For example. ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} However a single character variable is often more readable: ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} ::__[[==vvaarr]] Save the current variable value in `$_' or the named _v_a_r 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'. ::UU_n_e_w_v_a_l If the variable is undefined _n_e_w_v_a_l 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: ${_${.TARGET:T}_CFLAGS:U${DEF_CFLAGS}} If a value is only required if the variable is undefined, use: ${VAR:D:Unewval} ::DD_n_e_w_v_a_l If the variable is defined _n_e_w_v_a_l is the value. ::LL The name of the variable is the value. ::PP 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, then the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the rhs of a dependency. ::!!_c_m_d!! The output of running _c_m_d is the value. ::sshh If the variable is non-empty it is run as a command and the output becomes the new value. ::::==_s_t_r The variable is assigned the value _s_t_r after substitution. This modifier and its variations are useful in obscure situations such as wanting to set a variable when shell commands are being parsed. These assignment modifiers always expand to nothing, so if appearing in a rule line by themselves should be preceded with something to keep bbmmaakkee happy. The `::::' helps avoid false matches with the AT&T System V UNIX style ::== modifier and since substitution always occurs the ::::== form is vaguely appropriate. ::::??==_s_t_r As for ::::== but only if the variable does not already have a value. ::::++==_s_t_r Append _s_t_r to the variable. ::::!!==_c_m_d Assign the output of _c_m_d to the variable. ::[[_r_a_n_g_e]] Selects one or more words from the value, or performs other opera- tions related to the way in which the value is divided into words. Ordinarily, a value is treated as a sequence of words delimited by white space. Some modifiers suppress this behavior, causing a value to be treated as a single word (possibly containing embedded white space). 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 inte- gers (where index 1 represents the first word), and backwards using negative integers (where index -1 represents the last word). The _r_a_n_g_e is subjected to variable expansion, and the expanded result is then interpreted as follows: _i_n_d_e_x Selects a single word from the value. _s_t_a_r_t...._e_n_d Selects all words from _s_t_a_r_t to _e_n_d, inclusive. For example, `::[[22....--11]]' selects all words from the second word to the last word. If _s_t_a_r_t is greater than _e_n_d, then the words are out- put in reverse order. For example, `::[[--11....11]]' selects all the words from last to first. ** Causes subsequent modifiers to treat the value as a single word (possibly containing embedded white space). 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 white space. Analogous to the effect of "$@" in Bourne shell. ## Returns the number of words in the value. IINNCCLLUUDDEE SSTTAATTEEMMEENNTTSS,, CCOONNDDIITTIIOONNAALLSS AANNDD FFOORR LLOOOOPPSS Makefile inclusion, conditional structures and for loops reminiscent of the C programming language are provided in bbmmaakkee. All such structures are identified by a line beginning with a single dot (`.') character. Files are included with either ..iinncclluuddee <_f_i_l_e> or ..iinncclluuddee "_f_i_l_e". 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 expected to be in the system makefile directory. If double quotes are used, the including makefile's directory and any directories specified using the --II option are searched before the system makefile directory. For compatibility with other versions of bbmmaakkee `include file ...' is also accepted. If the include statement is written as ..--iinncclluuddee or as ..ssiinncclluuddee then errors locating and/or opening include files are ignored. If the include statement is written as ..ddiinncclluuddee not only are errors locating and/or opening include files ignored, but stale dependencies within the included file will be ignored just like _._M_A_K_E_._D_E_P_E_N_D_F_I_L_E. Conditional expressions are also preceded by a single dot as the first character of a line. The possible conditionals are as follows: ..eerrrroorr _m_e_s_s_a_g_e The message is printed along with the name of the makefile and line number, then bbmmaakkee will exit. ..eexxppoorrtt _v_a_r_i_a_b_l_e _._._. 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 --XX flag, so should be used with caution. For compatibility with other bbmmaakkee programs `export variable=value' is also accepted. Appending a variable name to _._M_A_K_E_._E_X_P_O_R_T_E_D is equivalent to exporting a variable. ..eexxppoorrtt--eennvv _v_a_r_i_a_b_l_e _._._. The same as `.export', except that the variable is not appended to _._M_A_K_E_._E_X_P_O_R_T_E_D. This allows exporting a value to the environ- ment which is different from that used by bbmmaakkee internally. ..eexxppoorrtt--lliitteerraall _v_a_r_i_a_b_l_e _._._. The same as `.export-env', except that variables in the value are not expanded. ..iinnffoo _m_e_s_s_a_g_e The message is printed along with the name of the makefile and line number. ..uunnddeeff _v_a_r_i_a_b_l_e Un-define the specified global variable. Only global variables may be un-defined. ..uunneexxppoorrtt _v_a_r_i_a_b_l_e _._._. The opposite of `.export'. The specified global _v_a_r_i_a_b_l_e will be removed from _._M_A_K_E_._E_X_P_O_R_T_E_D. If no variable list is provided, all globals are unexported, and _._M_A_K_E_._E_X_P_O_R_T_E_D deleted. ..uunneexxppoorrtt--eennvv Unexport all globals previously exported and clear the environ- ment inherited from the parent. This operation will cause a mem- ory leak of the original environment, so should be used spar- ingly. Testing for _._M_A_K_E_._L_E_V_E_L being 0, would make sense. Also note that any variables which originated in the parent environ- ment 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' will also be pushed into the new environment. ..wwaarrnniinngg _m_e_s_s_a_g_e The message prefixed by `_w_a_r_n_i_n_g_:' is printed along with the name of the makefile and line number. ..iiff [!]_e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.] Test the value of an expression. ..iiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] Test the value of a variable. ..iiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] Test the value of a variable. ..iiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] Test the target being built. ..iiffnnmmaakkee [!] _t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] Test the target being built. ..eellssee Reverse the sense of the last conditional. ..eelliiff [!] _e_x_p_r_e_s_s_i_o_n [_o_p_e_r_a_t_o_r _e_x_p_r_e_s_s_i_o_n _._._.] A combination of `..eellssee' followed by `..iiff'. ..eelliiffddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] A combination of `..eellssee' followed by `..iiffddeeff'. ..eelliiffnnddeeff [!]_v_a_r_i_a_b_l_e [_o_p_e_r_a_t_o_r _v_a_r_i_a_b_l_e _._._.] A combination of `..eellssee' followed by `..iiffnnddeeff'. ..eelliiffmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] A combination of `..eellssee' followed by `..iiffmmaakkee'. ..eelliiffnnmmaakkee [!]_t_a_r_g_e_t [_o_p_e_r_a_t_o_r _t_a_r_g_e_t _._._.] A combination of `..eellssee' followed by `..iiffnnmmaakkee'. ..eennddiiff End the body of the conditional. The _o_p_e_r_a_t_o_r may be any one of the following: |||| Logical OR. &&&& Logical AND; of higher precedence than ``||''. As in C, bbmmaakkee will only evaluate a conditional as far as is necessary to determine its value. Parentheses may be used to change the order of evaluation. The boolean operator `!!' may be used to logically negate an entire conditional. It is of higher precedence than `&&&&'. The value of _e_x_p_r_e_s_s_i_o_n may be any of the following: ddeeffiinneedd Takes a variable name as an argument and evaluates to true if the variable has been defined. mmaakkee Takes a target name as an argument and evaluates to true if the target was specified as part of bbmmaakkee's command line or was declared the default target (either implicitly or explicitly, see _._M_A_I_N) before the line containing the conditional. eemmppttyy Takes a variable, with possible modifiers, and evaluates to true if the expansion of the variable would result in an empty string. eexxiissttss Takes a file name as an argument and evaluates to true if the file exists. The file is searched for on the system search path (see _._P_A_T_H). ttaarrggeett Takes a target name as an argument and evaluates to true if the target has been defined. ccoommmmaannddss Takes a target name as an argument and evaluates to true if the target has been defined and has commands associated with it. _E_x_p_r_e_s_s_i_o_n may also be an arithmetic or string comparison. Variable expansion is performed on both sides of the comparison, after which the integral values are compared. A value is interpreted as hexadecimal if it is preceded by 0x, otherwise it is decimal; octal numbers are not sup- ported. The standard C relational operators are all supported. If after variable expansion, either the left or right hand side of a `====' or `!!==' operator is not an integral value, then string comparison is performed between the expanded variables. If no relational operator is given, it is assumed that the expanded variable is being compared against 0 or an empty string in the case of a string comparison. When bbmmaakkee is evaluating one of these conditional expressions, and it encounters a (white-space separated) word it doesn't recognize, either the ``make'' or ``defined'' expression is applied to it, depending on the form of the conditional. If the form is `..iiffddeeff', `..iiffnnddeeff', or `..iiff' the ``defined'' expression is applied. Similarly, if the form is `..iiffmmaakkee' or `..iiffnnmmaakkee, tthhee' ``make'' expression is applied. If the conditional evaluates to true the parsing of the makefile contin- ues as before. If it evaluates to false, the following lines are skipped. In both cases this continues until a `..eellssee' or `..eennddiiff' is found. For loops are typically used to apply a set of rules to a list of files. The syntax of a for loop is: ..ffoorr _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e _._._.] iinn _e_x_p_r_e_s_s_i_o_n ..eennddffoorr After the for eexxpprreessssiioonn is evaluated, it is split into words. On each iteration of the loop, one word is taken and assigned to each vvaarriiaabbllee, in order, and these vvaarriiaabblleess are substituted into the mmaakkee--rruulleess 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. CCOOMMMMEENNTTSS Comments begin with a hash (`#') character, anywhere but in a shell com- mand line, and continue to the end of an unescaped new line. SSPPEECCIIAALL SSOOUURRCCEESS ((AATTTTRRIIBBUUTTEESS)) ..EEXXEECC Target is never out of date, but always execute commands any- way. ..IIGGNNOORREE Ignore any errors from the commands associated with this tar- get, exactly as if they all were preceded by a dash (`-'). ..MMAADDEE Mark all sources of this target as being up-to-date. ..MMAAKKEE Execute the commands associated with this target even if the --nn or --tt options were specified. Normally used to mark recursive bbmmaakkees. ..MMEETTAA Create a meta file for the target, even if it is flagged as ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL. Usage in conjunction with ..MMAAKKEE is the most likely case. In "meta" mode, the target is out-of- date if the meta file is missing. ..NNOOMMEETTAA Do not create a meta file for the target. Meta files are also not created for ..PPHHOONNYY, ..MMAAKKEE, or ..SSPPEECCIIAALL targets. ..NNOOMMEETTAA__CCMMPP 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 will still be out of date. The same effect applies to any command line that uses the variable _._O_O_D_A_T_E, which can be used for that purpose even when not otherwise needed or desired: skip-compare-for-some: @echo this will be compared @echo this will not ${.OODATE:M.NOMETA_CMP} @echo this will also be compared The ::MM pattern suppresses any expansion of the unwanted vari- able. ..NNOOPPAATTHH Do not search for the target in the directories specified by ..PPAATTHH. ..NNOOTTMMAAIINN Normally bbmmaakkee 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. ..OOPPTTIIOONNAALL If a target is marked with this attribute and bbmmaakkee can't fig- ure out how to create it, it will ignore this fact and assume the file isn't needed or already exists. ..PPHHOONNYY The target does not correspond to an actual file; it is always considered to be out of date, and will not be created with the --tt option. Suffix-transformation rules are not applied to ..PPHHOONNYY targets. ..PPRREECCIIOOUUSS When bbmmaakkee is interrupted, it normally removes any partially made targets. This source prevents the target from being removed. ..RREECCUURRSSIIVVEE Synonym for ..MMAAKKEE. ..SSIILLEENNTT Do not echo any of the commands associated with this target, exactly as if they all were preceded by an at sign (`@'). ..UUSSEE Turn the target into bbmmaakkee'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 ..UUSSEE) of the source. If the target already has commands, the ..UUSSEE target's commands are appended to them. ..UUSSEEBBEEFFOORREE Exactly like ..UUSSEE, but prepend the ..UUSSEEBBEEFFOORREE target commands to the target. ..WWAAIITT If ..WWAAIITT 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 depen- dency 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 ..WWAAIITT is only relevant for parallel makes. SSPPEECCIIAALL TTAARRGGEETTSS Special targets may not be included with other targets, i.e. they must be the only target specified. ..BBEEGGIINN Any command lines attached to this target are executed before anything else is done. ..DDEEFFAAUULLTT This is sort of a ..UUSSEE rule for any target (that was used only as a source) that bbmmaakkee can't figure out any other way to cre- ate. Only the shell script is used. The ..IIMMPPSSRRCC variable of a target that inherits ..DDEEFFAAUULLTT's commands is set to the target's own name. ..DDEELLEETTEE__OONN__EERRRROORR 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. ..EENNDD Any command lines attached to this target are executed after everything else is done. ..EERRRROORR Any command lines attached to this target are executed when another target fails. The ..EERRRROORR__TTAARRGGEETT variable is set to the target that failed. See also MMAAKKEE__PPRRIINNTT__VVAARR__OONN__EERRRROORR. ..IIGGNNOORREE Mark each of the sources with the ..IIGGNNOORREE attribute. If no sources are specified, this is the equivalent of specifying the --ii option. ..IINNTTEERRRRUUPPTT If bbmmaakkee is interrupted, the commands for this target will be executed. ..MMAAIINN If no target is specified when bbmmaakkee is invoked, this target will be built. ..MMAAKKEEFFLLAAGGSS This target provides a way to specify flags for bbmmaakkee when the makefile is used. The flags are as if typed to the shell, though the --ff option will have no effect. ..NNOOPPAATTHH Apply the ..NNOOPPAATTHH attribute to any specified sources. ..NNOOTTPPAARRAALLLLEELL Disable parallel mode. ..NNOO__PPAARRAALLLLEELL Synonym for ..NNOOTTPPAARRAALLLLEELL, for compatibility with other pmake variants. ..OOBBJJDDIIRR The source is a new value for `_._O_B_J_D_I_R'. If it exists, bbmmaakkee will chdir(2) to it and update the value of `_._O_B_J_D_I_R'. ..OORRDDEERR The named targets are made in sequence. This ordering does not add targets to the list of targets to be made. Since the depen- dents of a target do not get built until the target 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 The ordering imposed by ..OORRDDEERR is only relevant for parallel makes. ..PPAATTHH 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 deleted. If the source is the special ..DDOOTTLLAASSTT target, then the current working directory is searched last. ..PPAATTHH.._s_u_f_f_i_x Like ..PPAATTHH but applies only to files with a particular suffix. The suffix must have been previously declared with ..SSUUFFFFIIXXEESS. ..PPHHOONNYY Apply the ..PPHHOONNYY attribute to any specified sources. ..PPRREECCIIOOUUSS Apply the ..PPRREECCIIOOUUSS attribute to any specified sources. If no sources are specified, the ..PPRREECCIIOOUUSS attribute is applied to every target in the file. ..SSHHEELLLL Sets the shell that bbmmaakkee will use to execute commands. The sources are a set of _f_i_e_l_d_=_v_a_l_u_e pairs. _n_a_m_e This is the minimal specification, used to select one of the built-in shell specs; _s_h, _k_s_h, and _c_s_h. _p_a_t_h Specifies the path to the shell. _h_a_s_E_r_r_C_t_l Indicates whether the shell supports exit on error. _c_h_e_c_k The command to turn on error checking. _i_g_n_o_r_e The command to disable error checking. _e_c_h_o The command to turn on echoing of commands executed. _q_u_i_e_t The command to turn off echoing of commands exe- cuted. _f_i_l_t_e_r The output to filter after issuing the _q_u_i_e_t com- mand. It is typically identical to _q_u_i_e_t. _e_r_r_F_l_a_g The flag to pass the shell to enable error checking. _e_c_h_o_F_l_a_g The flag to pass the shell to enable command echo- ing. _n_e_w_l_i_n_e 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'" ..SSIILLEENNTT Apply the ..SSIILLEENNTT attribute to any specified sources. If no sources are specified, the ..SSIILLEENNTT attribute is applied to every command in the file. ..SSTTAALLEE This target gets run when a dependency file contains stale entries, having _._A_L_L_S_R_C set to the name of that dependency file. ..SSUUFFFFIIXXEESS Each source specifies a suffix to bbmmaakkee. If no sources are specified, any previously specified suffixes are deleted. It allows the creation of suffix-transformation rules. Example: .SUFFIXES: .o .c.o: cc -o ${.TARGET} -c ${.IMPSRC} EENNVVIIRROONNMMEENNTT bbmmaakkee 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 bbmmaakkee and not as makefile variables; see the descrip- tion of `_._O_B_J_D_I_R' for more details. FFIILLEESS .depend list of dependencies Makefile list of dependencies makefile list of dependencies sys.mk system makefile /usr/share/mk system makefile directory CCOOMMPPAATTIIBBIILLIITTYY The basic make syntax is compatible between different versions of make; however the special variables, variable modifiers and conditionals are not. OOllddeerr vveerrssiioonnss An incomplete list of changes in older versions of bbmmaakkee: 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. 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. OOtthheerr mmaakkee ddiiaalleeccttss Other make dialects (GNU make, SVR4 make, POSIX make, etc.) do not sup- port most of the features of bbmmaakkee as described in this manual. Most notably: ++oo The ..WWAAIITT and ..OORRDDEERR declarations and most functionality per- taining to parallelization. (GNU make supports parallelization but lacks these features needed to control it effectively.) ++oo 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.) ++oo All built-in variables that begin with a dot. ++oo Most of the special sources and targets that begin with a dot, with the notable exception of ..PPHHOONNYY, ..PPRREECCIIOOUUSS, and ..SSUUFFFFIIXXEESS. ++oo Variable modifiers, except for the :old=new string substitution, which does not portably support globbing with `%' and historically only works on declared suffixes. ++oo 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 ..PPAATTHH functionality is based on an older feature VVPPAATTHH found in GNU make and many versions of SVR4 make; however, historically its behavior is too ill-defined (and too buggy) to rely upon. The $$@@ and $$<< variables are more or less universally portable, as is the $$((MMAAKKEE)) 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. SSEEEE AALLSSOO mkdep(1) HHIISSTTOORRYY bbmmaakkee 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). BBUUGGSS The make syntax is difficult to parse without actually acting of the data. For instance finding the end of a variable use should involve scanning each 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. -NetBSD 7.1_RC1 February 1, 2017 NetBSD 7.1_RC1 +NetBSD 7.1_RC1 June 22, 2017 NetBSD 7.1_RC1 Index: vendor/NetBSD/bmake/dist/buf.h =================================================================== --- vendor/NetBSD/bmake/dist/buf.h (revision 321026) +++ vendor/NetBSD/bmake/dist/buf.h (revision 321027) @@ -1,119 +1,119 @@ -/* $NetBSD: buf.h,v 1.17 2012/04/24 20:26:58 sjg Exp $ */ +/* $NetBSD: buf.h,v 1.19 2017/05/31 22:02:06 maya Exp $ */ /* * Copyright (c) 1988, 1989, 1990 The Regents of the University of California. * * This code is derived from software contributed to Berkeley by * Adam de Boor. * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * 1.

Its input is a list of specifications as to the files upon which programs and other files depend. If no .Fl f Ar makefile makefile option is given, .Nm will try to open .Ql Pa makefile then .Ql Pa Makefile in order to find the specifications. If the file .Ql 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" . .Pp .Nm will prepend the contents of the .Va 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 executing the commands to make 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 context. .It Fl d 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 .Va MAKEFLAGS environment variable and will be processed by any child make processes. By default, debugging information is printed to standard error, but this can be changed using the .Ar F debugging flag. The debugging output is always unbuffered; in addition, if debugging is enabled but debugging output is not directed to standard output, then the standard output is line buffered. .Ar Flags is one or more of the following: .Bl -tag -width Ds .It Ar A Print all possible debugging information; equivalent to specifying all of the debugging flags. .It Ar a Print debugging information about archive searching and caching. .It Ar C Print debugging information about current working directory. .It Ar c Print debugging information about conditional evaluation. .It Ar d Print debugging information about directory searching and caching. .It Ar e Print debugging information about failed commands and targets. .It Ar F Ns Oo Sy \&+ 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 .Ql F flag is .Ql \&+ , then the file will be opened in append mode; otherwise the file will be overwritten. If the file name is .Ql stdout or .Ql stderr then debugging output will be written to the standard output or standard error output file descriptors respectively (and the .Ql \&+ option has no effect). Otherwise, the output will be written to the named file. If the file name ends .Ql .%d then the .Ql %d is replaced by the pid. .It Ar f Print debugging information about loop evaluation. .It Ar "g1" Print the input graph before making anything. .It Ar "g2" Print the input graph after making everything, or before exiting on error. .It Ar "g3" Print the input graph before exiting on error. .It Ar j Print debugging information about running multiple shells. .It Ar l Print commands in Makefiles regardless of whether or not they are prefixed by .Ql @ or other "quiet" flags. Also known as "loud" behavior. .It Ar M Print debugging information about "meta" mode decisions about targets. .It Ar m Print debugging information about making targets, including modification dates. .It Ar 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 Ar p Print debugging information about makefile parsing. .It Ar s Print debugging information about suffix-transformation rules. .It Ar t Print debugging information about target list maintenance. .It Ar V Force the .Fl V -option to print raw values of variables. +option to print raw values of variables, overriding the default behavior +set via +.Va .MAKE.EXPAND_VARIABLES . .It Ar v Print debugging information about variable assignment. .It Ar x Run shell commands with .Fl x so the actual commands are printed as they are executed. .El .It Fl e Specify that environment variables override macro assignments within makefiles. .It Fl f Ar makefile Specify a makefile to read instead of the default .Ql Pa makefile . If .Ar makefile is .Ql Fl , 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 Fl 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 .Ar 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. The value is saved in .Va .MAKE.JOBS . Turns compatibility mode off, unless the .Ar B flag 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. .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 sys.mk and makefiles included via the .Ao Ar file Ac Ns -style include statement. The .Fl m option can be used multiple times to form a search path. This path will override the default system include path: /usr/share/mk. Furthermore the system include path will be appended to the search path used for .Qo Ar file Qc Ns -style include statements (see the .Fl I option). .Pp If a file or directory name in the .Fl m argument (or the .Ev MAKESYSPATH environment variable) starts with the string .Qq \&.../ then .Nm will search for the specified file or directory named in the remaining part of the argument string. The search starts with the current directory of the Makefile and then works upward towards the root of the file system. If the search is successful, then the resulting directory replaces the .Qq \&.../ specification in the .Fl m argument. If used, this feature allows .Nm to easily search in the current source tree for customized sys.mk files (e.g., by using .Qq \&.../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 .MAKE special source (see below). .It Fl N Display the commands which 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, but 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 Do not echo any commands as they are executed. Equivalent to specifying .Ql 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 -.Nm Ns 's -idea of the value of -.Ar variable , -in the global context. +Print the value of +.Ar variable . Do not build any targets. Multiple instances of this option may be specified; the variables will be printed one per line, with a blank line for each null or undefined variable. +The value printed is extracted from the global context after all +makefiles have been read. +By default, the raw variable contents (which may +include additional unexpanded variable references) are shown. If .Ar variable contains a .Ql \&$ -then the value will be expanded before printing. +then the value will be recursively expanded to its complete resultant +text before printing. +The expanded value will also be printed if +.Va .MAKE.EXPAND_VARIABLES +is set to true and +the +.Fl dV +option has not been used to override it. +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 the variable is always expanded to its complete value. .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 .Va MAKEFLAGS environment variable. This option may be useful on systems which have a small limit on the size of command arguments. .It Ar variable=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 seven different types of lines in a makefile: file dependency specifications, shell commands, variable assignments, include statements, conditional directives, for loops, and comments. .Pp In general, 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 usually created from them. The exact relationship between the target and the source is determined by the operator that separates them. The three operators are as follows: .Bl -tag -width flag .It Ic \&: A target is considered out-of-date if its modification time is less than those of any of its sources. Sources for a target accumulate over dependency lines when this operator is used. The target is removed if .Nm is interrupted. .It Ic \&! Targets are always re-created, but not until all sources have been examined and re-created as necessary. Sources for a target accumulate over dependency lines when this operator is used. The target is removed if .Nm is interrupted. .It Ic \&:: If no sources are specified, the target is always re-created. Otherwise, a target is considered out-of-date if any of its sources has been modified more recently than the target. Sources for a target do not accumulate over dependency lines when this operator is used. The target will not be removed if .Nm is interrupted. .El .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 must be used to describe 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 appear in many dependency lines if desired, by default only one of these rules may be followed by a creation script. If the .Ql Ic \&:: operator is used, however, all rules may include scripts and the 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 .Pq Ql \e in which case that line and the next are combined. .\" The escaped newline is retained and passed to the shell, which .\" normally ignores it. .\" However, the tab at the beginning of the following line is removed. If the first characters of the command are any combination of .Ql Ic @ , .Ql Ic + , or .Ql Ic \- , the command is treated specially. A .Ql Ic @ causes the command not to be echoed before it is executed. A .Ql Ic + causes the command to be executed even when .Fl 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. A .Ql Ic \- in compatibility mode causes any non-zero exit status of the command line to be ignored. .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 will be passed to the shell; otherwise .Nm will attempt direct execution. If a line starts with .Ql Ic \- and the shell has ErrCtl enabled then failure of the command line will be ignored as in compatibility mode. Otherwise .Ql Ic \- affects the entire job; the script will stop at the first command line that fails, but the target will not be 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 needs to use .Dq cd or .Dq chdir without potentially changing the directory for subsequent commands should be put in parentheses so it executes in a subshell. To force the use of one 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} $@); \e echo Back in `pwd` .Ed .Pp Since .Nm will .Xr chdir 2 to .Ql Va .OBJDIR before executing any targets, each child process starts with that as its current working directory. .Sh VARIABLE ASSIGNMENTS Variables in make are much like variables in the shell, and, by tradition, consist of all upper-case letters. .Ss Variable assignment modifiers The five operators that can be used to assign values to variables are as follows: .Bl -tag -width Ds .It Ic \&= Assign the value to the variable. Any previous value is overridden. .It Ic \&+= Append the value to the current value of the variable. .It Ic \&?= Assign the value to the variable if it is not already defined. .It Ic \&:= Assign with expansion, i.e. expand the value before assigning it to the variable. Normally, expansion is not done until the variable is referenced. .Em NOTE : References to undefined variables are .Em not expanded. This can cause problems when variable modifiers are used. .It Ic \&!= Expand the value and pass it to the shell for execution and assign the result to the variable. Any newlines in the result are replaced with spaces. .El .Pp Any white-space before the assigned .Ar value is removed; if the value is being appended, a single space is inserted between the previous contents of the variable and the appended value. .Pp Variables are expanded by surrounding the variable name with either curly braces .Pq Ql {} or parentheses .Pq Ql () and preceding it with a dollar sign .Pq Ql \&$ . If the variable name contains only a single letter, the surrounding braces or parentheses are not required. This shorter form is not recommended. .Pp If the variable name contains a dollar, then the name itself is expanded first. This allows almost arbitrary variable names, however names containing dollar, braces, parenthesis, or whitespace are really best avoided! .Pp If the result of expanding a variable contains a dollar sign .Pq Ql \&$ the string is expanded again. .Pp Variable substitution occurs at three 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 shell commands are expanded when the shell command is executed. .It .Dq .for loop index variables are expanded on each loop iteration. Note that other variables are not expanded inside loops so the following example code: .Bd -literal -offset indent .Dv .for i in 1 2 3 a+= ${i} j= ${i} b+= ${j} .Dv .endfor all: @echo ${a} @echo ${b} .Ed will print: .Bd -literal -offset indent 1 2 3 3 3 3 .Ed Because while ${a} contains .Dq 1 2 3 after the loop is executed, ${b} contains .Dq ${j} ${j} ${j} which expands to .Dq 3 3 3 since after the loop completes ${j} contains .Dq 3 . .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 are all built in and their values vary magically from target to target. It is not currently possible to define new local variables. The seven local variables are as follows: .Bl -tag -width ".ARCHIVE" -offset indent .It Va .ALLSRC The list of all sources for this target; also known as -.Ql Va \&\*[Gt] . +.Ql Va \&> . .It Va .ARCHIVE The name of the archive file; also known as .Ql 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 -.Ql Va \&\*[Lt] . +.Ql Va \&< . It is not defined in explicit rules. .It Va .MEMBER The name of the archive member; also known as .Ql Va % . .It Va .OODATE The list of sources for this target that were deemed out-of-date; also known as .Ql Va \&? . .It Va .PREFIX The file prefix of the target, containing only the file portion, no suffix or preceding directory components; also known as .Ql Va * . The suffix must be one of the known suffixes declared with .Ic .SUFFIXES or it will not be recognized. .It Va .TARGET The name of the target; also known as .Ql Va @ . For compatibility with other makes this is an alias for .Ic .ARCHIVE in archive member rules. .El .Pp The shorter forms -.Ql ( Va \*[Gt] , +.Ql ( Va > , .Ql Va \&! , -.Ql Va \*[Lt] , +.Ql Va < , .Ql Va % , .Ql Va \&? , .Ql Va * , and .Ql Va @ ) 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 Va $(@D) , are legacy forms equivalent to using the .Ql :H and .Ql :T modifiers. These forms are accepted for compatibility with .At V makefiles and POSIX but are not recommended. .Pp Four of the local variables may be used in sources on dependency lines because they expand to the proper value for each target on the line. These variables are .Ql Va .TARGET , .Ql Va .PREFIX , .Ql Va .ARCHIVE , and .Ql Va .MEMBER . .Ss Additional built-in variables In addition, .Nm sets or knows about the following variables: .Bl -tag -width .MAKEOVERRIDES .It Va \&$ A single dollar sign .Ql \&$ , i.e. .Ql \&$$ expands to a single dollar sign. .It Va .ALLTARGETS The list of all targets encountered in the Makefile. 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 .Ql Ev PWD for more details. .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. .It Ev MAKE The name that .Nm was executed with .Pq Va argv[0] . For compatibility .Nm also sets .Va .MAKE with the same value. The preferred variable to use is the environment variable .Ev MAKE because it is more compatible with other versions of .Nm and cannot be confused with the special target with the same name. .It Va .MAKE.DEPENDFILE Names the makefile (default .Ql Pa .depend ) from which generated dependencies are read. .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 .MAKE.JOBS The argument to the .Fl j option. .It Va .MAKE.JOB.PREFIX If .Nm is run with .Ar j then output for each target is prefixed with a token .Ql --- target --- the first part of which can be controlled via .Va .MAKE.JOB.PREFIX . If .Va .MAKE.JOB.PREFIX is empty, no token is printed. .br For example: .Li .MAKE.JOB.PREFIX=${.newline}---${.MAKE:T}[${.MAKE.PID}] would produce tokens like .Ql ---make[1234] target --- making it easier to track the degree of parallelism being achieved. .It Ev MAKEFLAGS The environment variable .Ql 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 .Ql Ev MAKEFLAGS variable which is then entered into the environment for all programs which .Nm executes. .It Va .MAKE.LEVEL The recursion depth of .Nm . The initial instance of .Nm will be 0, and an incremented value is put into the environment to be seen by the next generation. This allows tests like: .Li .if ${.MAKE.LEVEL} == 0 to protect things which should only be evaluated in the initial instance of .Nm . .It Va .MAKE.MAKEFILE_PREFERENCE The ordered list of makefile names (default .Ql Pa makefile , .Ql Pa Makefile ) that .Nm will look 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.MODE Processed after reading all makefiles. Can affect the mode that .Nm runs in. It can contain a number of keywords: .Bl -hang -width missing-filemon=bf. .It Pa compat Like .Fl B , puts .Nm into "compat" mode. .It Pa meta Puts .Nm into "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 very useful when diagnosing errors. .It Pa curdirOk= Ar bf Normally .Nm will not create .meta files in .Ql Va .CURDIR . This can be overridden by setting .Va bf to a value which represents True. .It Pa missing-meta= Ar bf If .Va bf is True, then a missing .meta file makes the target out-of-date. .It Pa missing-filemon= Ar bf If .Va bf is True, then missing filemon data makes the target out-of-date. .It Pa nofilemon Do not use .Xr filemon 4 . .It Pa env For debugging, it can be useful to include the environment in the .meta file. .It Pa 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 the value of: .Va .MAKE.META.PREFIX . .It Pa 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 .Ic .NOMETA_CMP . .It Pa silent= Ar bf If .Va bf is True, when a .meta file is created, mark the target .Ic .SILENT . .El .It Va .MAKE.META.BAILIWICK In "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.CREATED In "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 "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_PATHS Provides a list of path prefixes that should be ignored; because the contents are expected to change over time. The default list includes: .Ql 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.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.PREFIX Defines the message printed for each meta file updated in "meta verbose" mode. The default value is: .Dl Building ${.TARGET:H:tA}/${.TARGET:T} .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 .Ql Ev MAKEFLAGS . This behavior can be disabled by assigning an empty value to .Ql Va .MAKEOVERRIDES within a makefile. Extra variables can be exported from a makefile by appending their names to .Ql Va .MAKEOVERRIDES . .Ql Ev MAKEFLAGS is re-exported whenever .Ql 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 Va .MAKE.PPID The parent process-id of .Nm . .It Va .MAKE.SAVE_DOLLARS value should be a boolean that controls whether .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_PRINT_VAR_ON_ERROR When .Nm stops due to an error, it sets .Ql Va .ERROR_TARGET to the name of the target that failed, .Ql Va .ERROR_CMD to the commands of the failed target, and in "meta" mode, it also sets .Ql Va .ERROR_CWD to the .Xr getcwd 3 , and .Ql 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 .Ql Va .CURDIR as well as the value of any variables named in .Ql Va MAKE_PRINT_VAR_ON_ERROR . .It Va .newline This variable is simply assigned a newline character as its value. This allows expansions using the .Cm \&:@ modifier to put a newline between iterations of the loop rather than a space. For example, the printing of .Ql Va MAKE_PRINT_VAR_ON_ERROR could be done as ${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 .Ev ${MAKEOBJDIRPREFIX}${.CURDIR} .Pp (Only if .Ql Ev MAKEOBJDIRPREFIX is set in the environment or on the command line.) .It .Ev ${MAKEOBJDIR} .Pp (Only if .Ql Ev MAKEOBJDIR is set in the environment or on the command line.) .It .Ev ${.CURDIR} Ns Pa /obj. Ns Ev ${MACHINE} .It .Ev ${.CURDIR} Ns Pa /obj .It .Pa /usr/obj/ Ns Ev ${.CURDIR} .It .Ev ${.CURDIR} .El .Pp Variable expansion is performed on the value before it's used, so expressions such as .Dl ${.CURDIR:S,^/usr/src,/var/obj,} may be used. This is especially useful with .Ql Ev MAKEOBJDIR . .Pp .Ql Va .OBJDIR may be modified in the makefile via the special target .Ql Ic .OBJDIR . In all cases, .Nm will .Xr chdir 2 to the specified directory if it exists, and set .Ql Va .OBJDIR and .Ql Ev PWD to that directory before executing any targets. . .It Va .PARSEDIR A path to the directory of the current .Ql Pa Makefile being parsed. .It Va .PARSEFILE The basename of the current .Ql Pa Makefile being parsed. This variable and .Ql Va .PARSEDIR are both set only while the .Ql Pa Makefiles are being parsed. If you want to retain their current values, assign them to a variable using assignment with expansion: .Pq Ql Cm \&:= . .It Va .PATH A variable that represents the list of directories that .Nm will search for files. The search list should be updated using the target .Ql Va .PATH rather than the variable. .It Ev PWD Alternate path to the current directory. .Nm normally sets .Ql Va .CURDIR to the canonical path given by .Xr getcwd 3 . However, if the environment variable .Ql Ev PWD is set and gives a path to the current directory, then .Nm sets .Ql Va .CURDIR to the value of .Ql Ev PWD instead. This behavior is disabled if .Ql Ev MAKEOBJDIRPREFIX is set or .Ql Ev MAKEOBJDIR contains a variable transform. .Ql Ev PWD is set to the value of .Ql Va .OBJDIR for all programs which .Nm executes. .It Ev .TARGETS The list of targets explicitly specified on the command line, if any. .It Ev VPATH Colon-separated .Pq Dq \&: lists of directories that .Nm will search for files. The variable is supported for compatibility with old make programs only, use .Ql Va .PATH instead. .El .Ss Variable modifiers Variable expansion may be modified to select or modify each word of the variable (where a .Dq word is white-space delimited sequence of characters). The general format of a variable expansion is as follows: .Pp .Dl ${variable[:modifier[:...]]} .Pp Each modifier begins with a colon, which may be escaped with a backslash .Pq Ql \e . .Pp A set of modifiers can be specified via a variable, as follows: .Pp .Dl modifier_variable=modifier[:...] .Dl ${variable:${modifier_variable}[:...]} .Pp In this case the first modifier in the modifier_variable does not start with a colon, since that must appear in the referencing variable. If any of the modifiers in the modifier_variable contain a dollar sign .Pq Ql $ , these must be doubled to avoid early expansion. .Pp The supported modifiers are: .Bl -tag -width EEE .It Cm \&:E Replaces each word in the variable with its suffix. .It Cm \&:H Replaces each word in the variable with everything but the last component. .It Cm \&:M Ns Ar pattern Select only those words that match .Ar pattern . The standard shell wildcard characters .Pf ( Ql * , .Ql \&? , and .Ql Oo Oc ) 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, a construct like .Dl ${VAR:M*} will normalize the inter-word spacing, removing all leading and trailing space, and converting multiple consecutive spaces to single spaces. . .It Cm \&:N Ns Ar pattern This is identical to .Ql Cm \&:M , but selects all words which do not match .Ar pattern . .It Cm \&:O Order every word in variable alphabetically. To sort words in reverse order use the .Ql Cm \&:O:[-1..1] combination of modifiers. .It Cm \&:Ox Randomize words in variable. The results will be different each time you are referring to the modified variable; use the assignment with expansion .Pq Ql 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 variable, so that it can be passed safely through recursive invocations of .Nm . .It Cm \&:R Replaces each word in the variable with everything but its suffix. .It Cm \&:range[=count] The value is an integer sequence representing the words of the original value, or the supplied .Va count . .It Cm \&:gmtime[=utc] The value is a format string for .Xr strftime 3 , using .Xr gmtime 3 . If a .Va utc value is not provided or is 0, the current time is used. .It Cm \&:hash Compute a 32-bit hash of the value and encode it as hex digits. .It Cm \&:localtime[=utc] The value is a format string for .Xr strftime 3 , using .Xr localtime 3 . If a .Va utc value is not provided or is 0, the current time is used. .It Cm \&:tA Attempt to convert variable to an absolute path using .Xr realpath 3 , if that fails, the value is unchanged. .It Cm \&:tl Converts variable to lower-case letters. .It Cm \&:ts Ns Ar c Words in the variable are normally separated by a space on expansion. This modifier sets the separator to the character .Ar c . If .Ar c is omitted, then no separator is used. The common escapes (including octal numeric codes), work as expected. .It Cm \&:tu Converts variable to upper-case letters. .It Cm \&:tW Causes the value to be treated as a single word (possibly containing embedded white space). See also .Ql Cm \&:[*] . .It Cm \&:tw Causes the value to be treated as a sequence of words delimited by white space. See also .Ql Cm \&:[@] . .Sm off .It Cm \&:S No \&/ Ar old_string No \&/ Ar new_string No \&/ Op Cm 1gW .Sm on Modify the first occurrence of .Ar old_string in the variable's value, replacing it with .Ar new_string . If a .Ql g is appended to the last slash of the pattern, all occurrences in each word are replaced. If a .Ql 1 is appended to the last slash of the pattern, only the first word is affected. If a .Ql W is appended to the last slash of the pattern, then the value is treated as a single word (possibly containing embedded white space). 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 \*[Am] +.Pq Ql & is replaced by .Ar old_string (without any .Ql ^ or .Ql \&$ ) . Any character may be used as a delimiter for the parts of the modifier string. The anchoring, ampersand and delimiter characters may be escaped with a backslash .Pq Ql \e . .Pp Variable expansion occurs in the normal fashion inside both .Ar old_string and .Ar new_string with the single exception that a backslash is used to prevent the expansion of a dollar sign .Pq Ql \&$ , not a preceding dollar sign as is usual. .Sm off .It Cm \&:C No \&/ Ar pattern No \&/ Ar replacement No \&/ Op Cm 1gW .Sm on The .Cm \&:C modifier is just like the .Cm \&:S modifier except that the old and new strings, instead of being simple strings, are an extended regular expression (see .Xr regex 3 ) string .Ar pattern and an .Xr ed 1 Ns \-style string .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 white space). Note that .Ql 1 and .Ql g are orthogonal; the former specifies whether multiple words are potentially affected, the latter whether multiple substitutions can potentially occur within each affected word. .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 in the variable with its last component. .It Cm \&:u Remove 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 .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 itself - which will, of course, usually contain variable expansions. A common error is trying to use expressions like .Dl ${NUMBERS:M42:?match:no} which actually tests defined(NUMBERS), to determine is any words match "42" you need to use something like: .Dl ${"${NUMBERS:M42}" != \&"\&":?match:no} . .It Ar :old_string=new_string This is the .At V style variable substitution. It must be the last modifier specified. If .Ar old_string or .Ar new_string do not contain the pattern matching character .Ar % then it is assumed that they are anchored at the end of each word, so only suffixes or entire words may be replaced. Otherwise .Ar % is the substring of .Ar old_string to be replaced in .Ar new_string . .Pp Variable expansion occurs in the normal fashion inside both .Ar old_string and .Ar new_string with the single exception that a backslash is used to prevent the expansion of a dollar sign .Pq Ql \&$ , not a preceding dollar sign as is usual. .Sm off .It Cm \&:@ Ar temp 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. Assign .Ar temp to each word in the variable and evaluate .Ar string . The ODE convention is that .Ar temp should start and end with a period. For example. .Dl ${LINKS:@.LINK.@${LN} ${TARGET} ${.LINK.}@} .Pp However a single character variable is often more readable: .Dl ${MAKE_PRINT_VAR_ON_ERROR:@v@$v='${$v}'${.newline}@} .It Cm \&:_[=var] Save the current variable value in .Ql $_ or the named .Va 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, then the name of the variable is used. In order for this modifier to work, the name (node) must at least have appeared on the rhs of a dependency. .Sm off .It Cm \&:\&! Ar cmd Cm \&! .Sm on The output of running .Ar cmd is the value. .It Cm \&:sh If the variable is non-empty it 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 when shell commands are being parsed. These assignment modifiers always expand to nothing, so if appearing in a rule line by themselves should be preceded with something to keep .Nm happy. .Pp The .Ql Cm \&:: helps avoid false matches with the .At V style .Cm \&:= modifier and since substitution always occurs the .Cm \&::= 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 divided into words. .Pp Ordinarily, a value is treated as a sequence of words delimited by white space. Some modifiers suppress this behavior, causing a value to be treated as a single word (possibly containing embedded white space). An empty value, or a value that consists entirely of white-space, is treated as a single word. For the purposes of the .Ql 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, .Ql Cm \&:[2..-1] selects all words from the second word to the last word. If .Ar start is greater than .Ar end , then the words are output in reverse order. For example, .Ql Cm \&:[-1..1] selects all the words from last to first. .\" :[*] .It Cm \&* Causes subsequent modifiers to treat the value as a single word (possibly containing embedded white space). Analogous to the effect of \&"$*\&" in Bourne shell. .\" :[0] .It 0 Means the same as .Ql Cm \&:[*] . .\" :[*] .It Cm \&@ Causes subsequent modifiers to treat the value as a sequence of words delimited by white space. Analogous to the effect of \&"$@\&" in Bourne shell. .\" :[#] .It Cm \&# Returns the number of words in the value. .El \" :[range] .El .Sh INCLUDE STATEMENTS, CONDITIONALS AND FOR LOOPS Makefile inclusion, conditional structures and for loops reminiscent of the C programming language are provided in .Nm . All such structures are identified by a line beginning with a single dot .Pq Ql \&. character. Files are included with either .Cm \&.include Aq Ar file or .Cm \&.include Pf \*q Ar file Ns \*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. For compatibility with other versions of .Nm .Ql include file ... is also accepted. .Pp If the include statement is written as .Cm .-include or as .Cm .sinclude then 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 will be ignored just like .Va .MAKE.DEPENDFILE . .Pp Conditional expressions are also preceded by a single dot as the first character of a line. The possible conditionals are as follows: .Bl -tag -width Ds .It Ic .error Ar message The message is printed along with the name of the makefile and line number, then .Nm will exit. .It Ic .export Ar variable ... 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 .Nm programs .Ql export variable=value is also accepted. .Pp Appending a variable name to .Va .MAKE.EXPORTED is equivalent to exporting a variable. .It Ic .export-env Ar variable ... 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 ... The same as .Ql .export-env , except that variables in the value are not expanded. .It Ic .info Ar message The message is printed along with the name of the makefile and line number. .It Ic .undef Ar variable Un-define the specified global variable. Only global variables may be un-defined. .It Ic .unexport Ar variable ... The opposite of .Ql .export . The specified global .Va variable will be 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 will cause 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 .Ql Ev PATH , which is the minimal useful environment. Actually .Ql Ev .MAKE.LEVEL will also be pushed into the new environment. .It Ic .warning Ar message The message prefixed by .Ql Pa warning: is printed along with the name of the makefile and line number. .It Ic \&.if Oo \&! Oc Ns Ar expression Op Ar operator expression ... Test the value of an expression. .It Ic .ifdef Oo \&! Oc Ns Ar variable Op Ar operator variable ... Test the value of a variable. .It Ic .ifndef Oo \&! Oc Ns Ar variable Op Ar operator variable ... Test the value of a variable. .It Ic .ifmake Oo \&! Oc Ns Ar target Op Ar operator target ... Test the target being built. .It Ic .ifnmake Oo \&! Ns Oc Ar target Op Ar operator target ... Test the target being built. .It Ic .else Reverse the sense of the last conditional. .It Ic .elif Oo \&!

A combination of .Ql Ic .else followed by .Ql Ic .ifmake . .It Ic .elifnmake Oo \&! Oc Ns Ar target Op Ar operator target ... A combination of .Ql Ic .else followed by .Ql 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 -width "Cm XX" .It Cm \&|\&| Logical OR. -.It Cm \&\*[Am]\*[Am] +.It Cm \&&& Logical .Tn AND ; of higher precedence than .Dq \&|\&| . .El .Pp As in C, .Nm will only evaluate a conditional as far as is necessary to determine its value. Parentheses may be used to change the order of evaluation. The boolean operator .Ql Ic \&! may be used to logically negate an entire conditional. It is of higher precedence than -.Ql Ic \&\*[Am]\*[Am] . +.Ql Ic \&&& . .Pp The value of .Ar expression may be any of the following: .Bl -tag -width defined .It Ic defined Takes a variable name as an argument and evaluates to true if the variable has been defined. .It Ic make Takes a target name as an argument and 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. .It Ic empty Takes a variable, with possible modifiers, and evaluates to true if the expansion of the variable would result in an empty string. .It Ic exists Takes a file name as an argument and evaluates to true if the file exists. The file is searched for on the system search path (see .Va .PATH ) . .It Ic target Takes a target name as an argument and evaluates to true if the target has been defined. .It Ic commands Takes a target name as an argument and 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, after which the integral values are compared. A value is interpreted as hexadecimal if it is preceded by 0x, otherwise it is decimal; octal numbers are not supported. The standard C relational operators are all supported. If after variable expansion, either the left or right hand side of a .Ql Ic == or .Ql Ic "!=" operator is not an integral value, then string comparison is performed between the expanded variables. If no relational operator is given, it is assumed that the expanded variable is being compared against 0 or an empty string in the case of a string comparison. .Pp When .Nm is evaluating one of these conditional expressions, and it encounters a (white-space separated) word it doesn't recognize, either the .Dq make or .Dq defined expression is applied to it, depending on the form of the conditional. If the form is .Ql Ic .ifdef , .Ql Ic .ifndef , or .Ql Ic .if the .Dq defined expression is applied. Similarly, if the form is .Ql Ic .ifmake or .Ql Ic .ifnmake , the .Dq make expression is applied. .Pp If the conditional evaluates to true the parsing of the makefile continues as before. If it evaluates to false, the following lines are skipped. In both cases this continues until a .Ql Ic .else or .Ql Ic .endif is found. .Pp 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 ... Oc Ic in Ar expression .It Aq make-rules .It Ic \&.endfor .El .Pp After the for .Ic expression is evaluated, it is split into words. On each iteration of the loop, one word is taken and assigned to each .Ic variable , in order, and these .Ic variables are substituted into the .Ic make-rules 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. .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 "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 will still be 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 will be compared @echo this will not ${.OODATE:M.NOMETA_CMP} @echo this will also be 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 .Ic .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 will ignore this fact and assume 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 will not be 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 Exactly like .Ic .USE , but 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 . .br 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 .Ic .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. .It Ic .ERROR Any command lines attached to this target are executed when another target fails. The .Ic .ERROR_TARGET variable is set to the target that failed. See also .Ic 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 will be executed. .It Ic .MAIN If no target is specified when .Nm is invoked, this target will be built. .It Ic .MAKEFLAGS This target provides a way to specify flags for .Nm when the makefile is used. The flags are as if typed to the shell, though the .Fl f option will have no effect. .\" XXX: NOT YET!!!! .\" .It Ic .NOTPARALLEL .\" The named targets are executed in non parallel mode. .\" If no targets are .\" specified, then 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 .OBJDIR The source is a new value for .Ql Va .OBJDIR . If it exists, .Nm will .Xr chdir 2 to it and update the value of .Ql Va .OBJDIR . .It Ic .ORDER 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 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 The ordering imposed by .Ic .ORDER is only relevant for parallel makes. .\" XXX: NOT YET!!!! .\" .It Ic .PARALLEL .\" The named targets are executed in parallel mode. .\" If no targets are .\" specified, then 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 deleted. If the source is the special .Ic .DOTLAST target, then the current working directory is searched last. .It Ic .PATH. Ns Va 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 .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 .SHELL Sets the shell that .Nm will use to execute commands. The sources are a set of .Ar field=value pairs. .Bl -tag -width hasErrCtls .It Ar name This is the minimal specification, used to select one of the built-in shell specs; .Ar sh , .Ar ksh , and .Ar csh . .It Ar path Specifies the path to the shell. .It Ar hasErrCtl Indicates whether the shell supports exit on error. .It Ar check The command to turn on error checking. .It Ar ignore The command to disable error checking. .It Ar echo The command to turn on echoing of commands executed. .It Ar quiet The command to turn off echoing of commands executed. .It Ar filter The output to filter after issuing the .Ar quiet command. It is typically identical to .Ar quiet . .It Ar errFlag The flag to pass the shell to enable error checking. .It Ar echoFlag The flag to pass the shell to enable command echoing. .It Ar 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: .o \&.c.o: cc \-o ${.TARGET} \-c ${.IMPSRC} .Ed .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 .Ql Va .OBJDIR for more details. .Sh FILES .Bl -tag -width /usr/share/mk -compact .It .depend list of dependencies .It Makefile list of dependencies .It makefile list of dependencies .It sys.mk system makefile .It /usr/share/mk system makefile directory .El .Sh COMPATIBILITY The basic make syntax is compatible between different versions of make; 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 these 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.) .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 .Dl :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 .Ic .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 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 .Dq FRC has been used to FoRCe rebuilding (since the target/dependency does not exist... unless someone creates an .Dq FRC file). .Sh BUGS The .Nm syntax is difficult to parse without actually acting of the data. For instance finding the end of a variable use should involve scanning each 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.

Gerraty * install-mk (MK_VERSION): 20170424 * dirdeps.mk: set NO_DIRDEPS when bootstrapping. also target of bootstrap-this when sed is needed should be ${_want:T} 2017-04-18 Simon J. Gerraty * install-mk (MK_VERSION): 20170418 * auto.obj.mk: if using MAKEOBJDIRPREFIX check if it is a prefix match for .CURDIR - in which case .CURDIR *is* __objdir. 2017-04-01 Simon J. Gerraty * install-mk (MK_VERSION): 20170401 * meta2deps.py: add is_src so we can check if obj dependency is also a src dependency. 2017-03-26 Simon J. Gerraty * install-mk (MK_VERSION): 20170326 * meta.stage.mk: do nothing if NO_STAGING is defined. 2017-03-24 Simon J. Gerraty * auto.obj.mk: handle the case of __objdir=obj or obj.${MACHINE} etc. 2017-03-18 Simon J. Gerraty * mkopt.sh: treat WITH_*=NO like no; ie. WITHOUT_* 2017-03-01 Simon J. Gerraty * install-mk (MK_VERSION): 20170301 * dirdeps.mk (_build_all_dirs): update this outside test for empty DIRDEPS. * meta.stage.mk: allow multiple inclusion to the extent it makes sense. 2017-02-14 Simon J. Gerraty * prog.mk (install_links): depends on realinstall 2017-02-12 Simon J. Gerraty * install-mk (MK_VERSION): 20170212 * dpadd.mk: avoid applying :T:R twice to DPLIBS entries 2017-01-30 Simon J. Gerraty * install-mk (MK_VERSION): 20170130 * dirdeps.mk: use :range if we can. * sys.vars.mk: provide M_cmpv if MAKE_VERSION >= 20170130 * meta2deps.py: clean paths without using realpath() where possible. fix sort_unique. 2016-12-12 Simon J. Gerraty * install-mk (MK_VERSION): 20161212 * meta2deps.py: set pid_cwd[pid] when we process 'C'hdir, rather than when we detect pid change. 2016-12-07 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-${VERSION}.tgz but want to be able to use foo.tgz to reference the latest staged version - so we make foo.tgz a symlink to it. Using a target to do both operations ensures we stay in sync. 2016-11-26 Simon J. Gerraty * install-mk (MK_VERSION): 20161126 * dirdeps.mk: set DIRDEPS_CACHE before we include local.dirdeps.mk so it can add dependencies. 2016-10-10 Simon J. Gerraty * dirdeps.mk: set DEP_* before we expand .MAKE.DEPENDFILE_PREFERENCE do that they can influence the result correctly. * dirdeps.mk (${DIRDEPS_CACHE}): make sure we pass on TARGET_SPEC * dirdeps.mk: Add ONLY_TARGET_SPEC_LIST and NOT_TARGET_SPEC_LIST similar to ONLY_MACHINE_LIST and NOT_MACHINE_LIST 2016-10-05 Simon J. Gerraty * dirdeps.mk: remove dependence on jot (normal situations anyway). 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 * 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 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 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 * 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 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 * 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 to 20060301 * autodep.mk (.depend): if MAKE_VERSION is newer than 20050530 we can make .END depend on .depend and make .depend depend on __depsrcs that exist. * dpadd.mk: add SRC_PATHADD 2005-11-04 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20051104 * prog.mk: remove all the LIBC?= junk, use .-include libnames.mk instead (none by default). also if USE_DPADD_MK is set, include that. 2005-10-09 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20051001 Add UnixWare.sys.mk from Klaus Heinz. 2005-04-05 Simon J. Gerraty * install-mk: always install *.sys.mk and if need be symlink one to sys.mk 2005-03-22 Simon J. Gerraty * subdir.mk, own.mk: use .MAKE rather than MAKE 2004-02-15 Simon J. Gerraty * own.mk: don't use NetBSD's _SRC_TOP_ it can cause confusion. Also don't take just 'mk' as a srctop indicator. 2004-02-14 Simon J. Gerraty * warnings.mk: overhauled, now very powerful. 2004-02-03 Simon J. Gerraty * Generic.sys.mk: need to use ${.PARSEDIR} with exists(). 2004-02-01 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20040201 * extract HOST_TARGET stuff to host-target.mk so own.mk and Generic.sys.mk can share. * fix typo in autodep.mk _SUBDIRUSE not _SUBDIR. 2003-09-30 Simon J. Gerraty * install-mk (MK_VERSION): 20030930 * rename generic.sys.mk to Generic.sys.mk so that it does not get installed (unless being used as sys.mk) * set OS and ROOT_GROUP for those that we know the value. for others (eg. Generic.sys.mk) wrap the != in an .ifndef so we don't do it again for each sub-make. 2003-09-28 Simon J. Gerraty * install-mk (MK_VERSION): 20030928 Add some extra *.sys.mk from bootstrap-pkgsrc some of these likely still need work. Make everything default to root:wheel ownership, sys.mk can set ROOT_GROUP accordingly. 2003-08-07 Simon J. Gerraty * install-mk: if FORCE_BSD_MK={cp,ln} use the ones in SYS_MK_DIR not the portable ones. 2003-07-31 Simon J. Gerraty * install-mk: add ability to use cp -f when updating destination .mk files. Also now possible to play games with FORCE_SYS_MK=ln etc on *BSD machines to link /usr/share/mk/sys.mk into dest - not recommended unless you seriously want to. 2003-07-28 Simon J. Gerraty * own.mk (IMPFLAGS): add support for COPTS.${IMPSRC:T} etc for semi-compatability with NetBSD. 2003-07-23 Simon J. Gerraty * install-mk: add a version indicator 2003-07-22 Simon J. Gerraty * prog.mk: don't try and use ${LIBCRT0} if its /dev/null * install-mk: Allow FORCE_SYS_MK to come from env Index: vendor/NetBSD/bmake/dist/mk/dirdeps.mk =================================================================== --- vendor/NetBSD/bmake/dist/mk/dirdeps.mk (revision 321026) +++ vendor/NetBSD/bmake/dist/mk/dirdeps.mk (revision 321027) @@ -1,795 +1,805 @@ -# $Id: dirdeps.mk,v 1.88 2017/04/24 20:34:59 sjg Exp $ +# $Id: dirdeps.mk,v 1.89 2017/05/17 17:41:47 sjg Exp $ # Copyright (c) 2010-2013, Juniper Networks, Inc. # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.

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). # # BUILD_AT_LEVEL0 # Indicates whether .MAKE.LEVEL 0 builds anything: # if "no" sub-makes are used to build everything, # if "yes" sub-makes are only used to build for other machines. # It is best to use "no", but this can require fixing some # makefiles to not do anything at .MAKE.LEVEL 0. # # 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. # .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 .if !target(_DIRDEP_USE) # do some setup we only need once _CURDIR ?= ${.CURDIR} _OBJDIR ?= ${.OBJDIR} now_utc = ${%s:L:gmtime} .if !defined(start_utc) start_utc := ${now_utc} .endif .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 .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.
