number of tests o replace enums with bitfields, this simplifies a lot of code. o var.c: refactor ParseModifierPartSubst 2021-10-24 Simon J Gerraty * VERSION (_MAKE_VERSION): 20211024 Merge with NetBSD make, pick up o Punt on write errors - ENOSPC etc. 2021-10-22 Simon J Gerraty * configure.in: use_defshell, set both DEFSHELL_INDEX and defshell_path if appropriate. This makes it easier to use say the KSH specification with and alternate path for the shell. * configure.in compat.c: for SCO we need to force UseShell * configure.in: SCO /bin/sh is not usable, provide a list of alternatives for use as .SHELL. We still have to mark some tests as broken, plus more if we end up with ksh as .SHELL. Issue a warning about skipped tests. * boot-strap: leave TOOL_DIFF to configure * configure.in: on SCO native cc is not usable, gcc is to be found in /usr/gnu/bin and while ancient is at least able to compile bmake. Thus we add /usr/gnu/bin to PATH if it exists, and later check if $CC would have been found via $PATH. If not we set CC to the full path of $CC. Also gnu diff is known to support -u, so if it exists use it. * configure.in: move getopt to AC_REPLACE_FUNCS also add AC_C_INLINE - in an attempt to compile using native cc on SCO. * configure.in: check for stresep as well as strsep, since we define the later to the former if necessary, and if we have to provide stresep we also need to provide a prototype. * configure.in: we no longer need to worry about sys/cdefs.h providing __RCSID which simplifies things quite a bit. * make.h: make sure we have __RCSID * unit-tests/Makefile.config.in: add TOOL_DIFF so configure can control it. 2021-10-20 Simon J Gerraty * VERSION: 20211020 Merge with NetBSD make, pick up o confirm sync of unit-tests 2021-10-18 Simon J Gerraty * configure.in: check if timezone Europe/Berlin is supported if not try UTC-1 * configure.in: if .OBJDIR is $srcdir/obj we need to create a symlink unit-tests -> ../unit-tests/obj so that unit-tests/Makefile.config is put in the right place. * refine filtering of .OBJDIR in unit-tests 2021-10-16 Simon J Gerraty * Fix unit-tests on Minix 3.2.0 o job.c: do not punt if read of token pipe fails for EAGAIN. On Minix at least, we are not ready to read the childExitJob pipe when poll says we are. There should actually be no reason for this pipe to be non-blocking, but while that works fine on {Net,Free}BSD it breaks another test case on Minix. o unit-tests/Makefile: deal with variants of error messages and use of obj as .OBJDIR 2021-10-14 Simon J Gerraty * configure.in: add sigaction to AC_REPLACE_FUNCS we also need to check for sigaddset etc just for the benefit of sigact.c * Add sigact.c as sigaction.c so this "just works". This should have been done back when bmake_signal started using sigaction (I only just noticed that sigact.c wasn't here ;-) Note: I no longer have access to any system where this would matter.

Gerraty * 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 diff --git a/Makefile b/Makefile index 3332dcdeaf2d..65730df7e3df 100644 --- a/Makefile +++ b/Makefile @@ -1,237 +1,237 @@ -# $Id: Makefile,v 1.126 2024/03/10 17:46:44 sjg Exp $ +# $Id: Makefile,v 1.127 2024/03/19 16:03:23 sjg Exp $ PROG= bmake SRCS= \ arch.c \ buf.c \ compat.c \ cond.c \ dir.c \ for.c \ hash.c \ job.c \ lst.c \ main.c \ make.c \ make_malloc.c \ meta.c \ metachar.c \ parse.c \ str.c \ suff.c \ targ.c \ trace.c \ util.c \ var.c .-include "VERSION" .-include "Makefile.inc" # 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}\"" -.for x in FORCE_MACHINE FORCE_MACHINE_ARCH +.for x in FORCE_MAKE_OS FORCE_MACHINE FORCE_MACHINE_ARCH .ifdef $x COPTS.main.c+= "-D$x=\"${$x}\"" .endif .endfor # meta mode can be useful even without filemon # should be set by now USE_FILEMON ?= no .if ${USE_FILEMON:tl} != "no" .PATH: ${srcdir}/filemon SRCS+= filemon_${USE_FILEMON}.c COPTS.meta.c+= -DUSE_FILEMON -DUSE_FILEMON_${USE_FILEMON:tu} COPTS.job.c+= ${COPTS.meta.c} .if ${USE_FILEMON} == "dev" FILEMON_H ?= /usr/include/dev/filemon/filemon.h .if exists(${FILEMON_H}) && ${FILEMON_H:T} == "filemon.h" COPTS.filemon_dev.c += -DHAVE_FILEMON_H -I${FILEMON_H:H} .endif .elif ${USE_FILEMON} == "ktrace" COPTS.filemon_ktrace.c += -Wno-error=unused-parameter .endif .endif # USE_FILEMON .PATH: ${srcdir} .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...

Variable assign- -ments should follow options for POSIX compatibility but no order- -ing is enforced. There are several different types of lines in a -makefile: dependency specifications, shell commands, variable as- -signments, include statements, conditional directives, for loops, -other directives, and comments. Lines may be continued from one -line to the next by ending them with a backslash The trailing -newline character and initial whitespace on the following line -are compressed into a single space. Dependency lines consist of -one or more targets, an operator, and zero or more sources. This -creates a relationship where the targets on the sources and are -customarily created from them. A target is considered out of -date if it does not exist, or if its modification time is less -than that of any of its sources. An out-of-date target is re- -created, but not until all sources have been examined and them- -selves re-created as needed. Three operators may be used: Many -dependency lines may name this target but only one may have at- -tached shell commands. All sources named in all dependency lines -are considered together, and if needed the attached shell com- -mands are run to create or re-create the target. If is inter- -rupted, the target is removed. The same, but the target is al- -ways re-created whether or not it is out of date. Any dependency -line may have attached shell commands, but each one is handled -independently: its sources are considered and the attached shell -commands are run if the target is out of date with respect to -(only) those sources. Thus, different groups of the attached -shell commands may be run depending on the circumstances. Fur- -thermore, unlike for dependency lines with no sources, the at- -tached shell commands are always run. Also unlike the target is -not removed if is interrupted. All dependency lines mentioning a -particular target must use the same operator. Targets and -sources may contain the shell wildcard values and The values and -may only be used as part of the final component of the target or -source, and only match existing files. The value need not neces- -sarily be used to describe existing files. Expansion is in di- -rectory order, not alphabetically as done in the shell. 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 be preceded by a tab. (For historical reasons, -spaces are not accepted.) While targets can occur in many depen- -dency 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 respective scripts are ex- -ecuted in the order found. Each line is treated as a separate -shell command, unless the end of line is escaped with a backslash -in which case that line and the next are combined. If the first -characters of the command are any combination of or the command -is treated specially. causes the command not to be echoed before -it is executed. causes the command to be executed even when is -given. This is similar to the effect of the special source, ex- -cept that the effect can be limited to a single line of a script. -in compatibility mode causes any non-zero exit status of the com- -mand line to be ignored. When is run in jobs mode with the en- -tire 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 char- -acters it is passed to the shell; otherwise attempts direct exe- -cution. If a line starts with and the shell has ErrCtl enabled, -failure of the command line is ignored as in compatibility mode. -Otherwise affects the entire job; the script stops at the first -command line that fails, but the target is not deemed to have -failed. Makefiles should be written so that the mode of opera- -tion does not change their behavior. For example, any command -which uses or without the intention of changing the directory for -subsequent commands should be put in parentheses so it executes -in a subshell. To force the use of a single shell, escape the -line breaks so as to make the whole script one command. For ex- -ample: 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 changes the current working -directory to before executing any targets, each child process -starts with that as its current working directory. Variables in -make behave much like macros in the C preprocessor. Variable as- -signments have the form where: is a single-word variable name, -consisting, by tradition, of all upper-case letters, is one of -the variable assignment operators described below, and is inter- -preted according to the variable assignment operator. Whitespace -around and is discarded. The five operators that assign values -to variables are: Assign the value to the variable. Any previous -value is overwritten. Append the value to the current value of -the variable, separating them by a single space. Assign the -value to the variable if it is not already defined. Expand the -value, then assign it to the variable. References to undefined -variables are expanded. This can cause problems when variable -modifiers are used. Expand the value and pass it to the shell -for execution, then assign the output from the child's standard -output to the variable. Any newlines in the result are replaced -with spaces. In most contexts where variables are expanded, ex- -pands to a single dollar sign. In other contexts (most variable -modifiers, string literals in conditions), expands to a single -dollar sign. References to variables have the form or If the -variable name consists of only a single character and the expres- -sion contains no modifiers, the surrounding curly braces or -parentheses are not required. This shorter form is not recom- -mended. If the variable name contains a dollar, the name itself -is expanded first. This allows almost arbitrary variable names, -however names containing dollar, braces, parentheses or white- -space are really best avoided. If the result of expanding a -nested variable expression contains a dollar sign the result is -subject to further expansion. Variable substitution occurs at -four distinct times, depending on where the variable is being -used. Variables in dependency lines are expanded as the line is -read. Variables in conditionals are expanded individually, but -only as far as necessary to determine the result of the condi- -tional. Variables in shell commands are expanded when the shell -command is executed. loop index variables are expanded on each -loop iteration. Note that other variables are not expanded when -composing the body of a loop, so the following example code: .for -i in 1 2 3 a+= ${i} j= ${i} b+= ${j} .endfor - -all: @echo ${a} @echo ${b} prints: 1 2 3 3 3 3 -After the loop is executed: contains which expands to contains -which expands to contains which expands to and further to The -four different classes of variables (in order of increasing -precedence) are: Variables defined as part of environment. Vari- -ables defined in the makefile or in included makefiles. Vari- -ables defined as part of the command line. Variables that are -defined specific to a certain target. Local variables can be set -on a dependency line, unless is set to The rest of the line -(which already has had global variables expanded) is the variable -value. For example: COMPILER_WRAPPERS= ccache distcc icecc - -${OBJS}: .MAKE.META.CMP_FILTER=${COMPILER_WRAPPERS:S,^,N,} Only -the targets are impacted by that filter (in mode) and simply en- -abling/disabling any of the compiler wrappers does not render all -of those targets out-of-date. target-local variable assignments -behave differently in that; Only appends to a previous local as- -signment for the same target and variable. Is redundant with re- -spect to global variables, which have already been expanded. The -seven built-in local variables are: The list of all sources for -this target; also known as The name of the archive file; also -known as In suffix-transformation rules, the name/path of the -source from which the target is to be transformed (the source); -also known as It is not defined in explicit rules.

It is handy for setting per-target -CFLAGS for instance: If a value is only required if the variable -is undefined, use: If the variable is defined, (which may be -empty) is the value. The name of the variable is the value. The -path of the node which has the same name as the variable is the -value. If no such node exists or its path is null, the name of -the variable is used. In order for this modifier to work, the -name (node) must at least have appeared on the right-hand side of -a dependency. The output of running is the value. The value is -run as a command, and the output becomes the new value. The -variable is assigned the value after substitution. This modifier -and its variations are useful in obscure situations such as want- -ing to set a variable at a point where a target's shell commands -are being parsed. These assignment modifiers always expand to -nothing. The helps avoid false matches with the style modifier -and since substitution always occurs, the form is vaguely appro- -priate.

The --XX flag disables this behavior. + Variable assignments should follow options for POSIX + compatibility but no ordering is enforced. + + There are several different types of lines in a makefile: dependency + specifications, shell commands, variable assignments, include statements, + conditional directives, for loops, other directives, and comments. + + Lines may be continued from one line to the next by ending them with a + backslash (`\'). The trailing newline character and initial whitespace + on the following line are compressed into a single space. + +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 customarily created from them. A target is + considered out of date if it does not exist, or if its modification time + is less than that of any of its sources. An out-of-date target is re- + created, but not until all sources have been examined and themselves re- + created as needed. Three operators may be used: + + :: Many dependency lines may name this target but only one may have + attached shell commands. All sources named in all dependency lines + are considered together, and if needed the attached shell commands + are run to create or re-create the target. If bbmmaakkee is + interrupted, the target is removed. + + !! The same, but the target is always re-created whether or not it is + out of date. + + :::: Any dependency line may have attached shell commands, but each one + is handled independently: its sources are considered and the + attached shell commands are run if the target is out of date with + respect to (only) those sources. Thus, different groups of the + attached shell commands may be run depending on the circumstances. + Furthermore, unlike ::, for dependency lines with no sources, the + attached shell commands are always run. Also unlike ::, the target + is not removed if bbmmaakkee is interrupted. + + All dependency lines mentioning a particular target must use the same + operator. + + Targets and sources may contain the shell wildcard values `?', `*', `[]', + and `{}'. The values `?', `*', and `[]' may only be used as part of the + final component of the target or source, and only match existing files. + The value `{}' need not necessarily be used to describe existing files. + Expansion is in directory order, not alphabetically as done in the shell. + +SSHHEELLLL CCOOMMMMAANNDDSS + 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 _m_u_s_t be preceded by a tab. (For historical reasons, spaces are + not accepted.) While targets can occur in many dependency lines if + desired, by default only one of these rules may be followed by a creation + script. If the `::::' operator is used, however, all rules may include + scripts, and the respective scripts are executed in the order found. + + Each line is treated as a separate shell command, unless the end of line + is escaped with a backslash `\', in which case that line and the next are + combined. If the first characters of the command are any combination of + `@@', `++', or `--', the command is treated specially. + + @@ causes the command not to be echoed before it is executed. + + ++ causes the command to be executed even when --nn is given. + This is similar to the effect of the _._M_A_K_E special source, + except that the effect can be limited to a single line of a + script. + + -- in compatibility mode causes any non-zero exit status of + the command line to be ignored. + + When 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 + command contains any shell meta characters (`#=|^(){};&<>*?[]:$`\\n'), it + is passed to the shell; otherwise bbmmaakkee attempts direct execution. If a + line starts with `--' and the shell has ErrCtl enabled, failure of the + command line is ignored as in compatibility mode. Otherwise `--' affects + the entire job; the script stops at the first command line that fails, + but the target is not deemed to have failed. + + Makefiles should be written so that the mode of bbmmaakkee operation does not + change their behavior. For example, any command which uses "cd" or + "chdir" without the intention of changing the directory for subsequent + commands should be put in parentheses so it executes in a subshell. To + force the use of a single shell, escape the line breaks so as to make the + whole script one command. For example: + + avoid-chdir-side-effects: + @echo "Building $@ in $$(pwd)" + @(cd ${.CURDIR} && ${MAKE} $@) + @echo "Back in $$(pwd)" + + ensure-one-shell-regardless-of-mode: + @echo "Building $@ in $$(pwd)"; \ + (cd ${.CURDIR} && ${MAKE} $@); \ + echo "Back in $$(pwd)" + + Since bbmmaakkee changes the current working directory 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 behave much like macros in the C preprocessor. + Variable assignments have the form `_N_A_M_E _o_p _v_a_l_u_e', where: + _N_A_M_E is a single-word variable name, consisting, by tradition, + of all upper-case letters, + _o_p is one of the variable assignment operators described + below, and + _v_a_l_u_e is interpreted according to the variable assignment + operator. + Whitespace around _N_A_M_E, _o_p and _v_a_l_u_e is discarded. + VVaarriiaabbllee aassssiiggnnmmeenntt ooppeerraattoorrss + The five operators that assign values to variables are: + == Assign the value to the variable. Any previous value is + overwritten. + ++== Append the value to the current value of the variable, separating + them by a single space. + ??== Assign the value to the variable if it is not already defined. + ::== Expand the value, then assign it to the variable. + _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, then + assign the output from the child's standard output to the + variable. Any newlines in the result are replaced with spaces. + EExxppaannssiioonn ooff vvaarriiaabblleess + In most contexts where variables are expanded, `$$' expands to a single + dollar sign. In other contexts (most variable modifiers, string literals + in conditions), `\$' expands to a single dollar sign. + References to variables have the form $${{_n_a_m_e[::_m_o_d_i_f_i_e_r_s]}} or + $$((_n_a_m_e[::_m_o_d_i_f_i_e_r_s])). If the variable name consists of only a single + character and the expression contains no modifiers, the surrounding curly + braces or parentheses are not required.

This allows almost arbitrary variable names, however names + containing dollar, braces, parentheses or whitespace are really best + avoided. + If the result of expanding a nested variable expression contains a dollar + sign (`$'), the result is subject to further expansion. + Variable substitution occurs at four distinct times, depending on where + the variable is being used. + 1.

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 changes to the specified + directory if it exists, and sets `_._O_B_J_D_I_R' and `_P_W_D' to that + directory before executing any targets. + + Except in the case of an explicit `..OOBBJJDDIIRR' target, bbmmaakkee checks + that the specified directory is writable and ignores it if not. + This check can be skipped by setting the environment variable + `MAKE_OBJDIR_CHECK_WRITABLE' to "no". + + _._P_A_R_S_E_D_I_R + The directory name of the current makefile being parsed. + + _._P_A_R_S_E_F_I_L_E + The basename of the current makefile being parsed. This variable + and `_._P_A_R_S_E_D_I_R' are both set only while the makefiles are being + parsed. To retain their current values, assign them to a + variable using assignment with expansion `::=='. + + _._P_A_T_H The space-separated list of directories that bbmmaakkee searches for + files. To update this search list, use the special target + `..PPAATTHH' rather than modifying the variable directly. + + _%_P_O_S_I_X Is set in POSIX mode, see the special `_._P_O_S_I_X' target. + + _P_W_D 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, 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. `_P_W_D' is set to + the value of `_._O_B_J_D_I_R' for all programs which bbmmaakkee executes. + + _._S_H_E_L_L The pathname of the shell used to run target scripts. It is + read-only. + + _._S_U_F_F_I_X_E_S + The list of known suffixes. It is read-only. + + _._S_Y_S_P_A_T_H + The space-separated list of directories that bbmmaakkee searches for + makefiles, referred to as the system include path. To update + this search list, use the special target `..SSYYSSPPAATTHH' rather than + modifying the variable which is read-only. + + _._T_A_R_G_E_T_S + The list of targets explicitly specified on the command line, if + any. + + _V_P_A_T_H The colon-separated (":") list of directories that bbmmaakkee searches + for files. This variable is supported for compatibility with old + make programs only, use `_._P_A_T_H' instead. + + VVaarriiaabbllee mmooddiiffiieerrss + The general format of a variable expansion is: + + $${{_v_a_r_i_a_b_l_e[::_m_o_d_i_f_i_e_r[::...]]}} + + Each modifier begins with a colon. To escape a colon, precede it with a + backslash `\'. + + A list of indirect modifiers can be specified via a variable, as follows: + + _m_o_d_i_f_i_e_r___v_a_r_i_a_b_l_e = _m_o_d_i_f_i_e_r[::...] + + $${{_v_a_r_i_a_b_l_e::$${{_m_o_d_i_f_i_e_r___v_a_r_i_a_b_l_e}}[::...]}} + + In this case, the first modifier in the _m_o_d_i_f_i_e_r___v_a_r_i_a_b_l_e does not start + with a colon, since that colon already occurs in the referencing + variable. If any of the modifiers in the _m_o_d_i_f_i_e_r___v_a_r_i_a_b_l_e contains a + dollar sign (`$'), these must be doubled to avoid early expansion. + + Some modifiers interpret the expression value as a single string, others + treat the expression value as a whitespace-separated list of words. When + splitting a string into words, whitespace can be escaped using double + quotes, single quotes and backslashes, like in the shell. The quotes and + backslashes are retained in the words. + + The supported modifiers are: + + ::EE Replaces each word with its suffix. + + ::HH Replaces each word with its dirname. + + ::MM_p_a_t_t_e_r_n + Selects 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, + the construct `${VAR:M*}' removes all leading and trailing + whitespace and normalizes the inter-word spacing to a single space. + + ::NN_p_a_t_t_e_r_n + This is the opposite of `::MM', selecting all words which do _n_o_t match + _p_a_t_t_e_r_n. + + ::OO Orders the words lexicographically. + + ::OOnn Orders the words numerically. A number followed by one of `k', `M' + or `G' is multiplied by the appropriate factor, which is 1024 for + `k', 1048576 for `M', or 1073741824 for `G'. Both upper- and lower- + case letters are accepted. + + ::OOrr Orders the words in reverse lexicographical order. + + ::OOrrnn + Orders the words in reverse numerical order. + + ::OOxx Shuffles the words. The results are 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 value, so that it can be + passed safely to the shell. + + ::qq Quotes every shell meta-character in the value, and also doubles `$' + characters so that it can be passed safely through recursive + invocations of bbmmaakkee. This is equivalent to `::SS//\\$$//&&&&//gg::QQ'. + + ::RR Replaces each word with everything but its suffix. + + ::rraannggee[==_c_o_u_n_t] + The value is an integer sequence representing the words of the + original value, or the supplied _c_o_u_n_t. + + ::ggmmttiimmee[==_t_i_m_e_s_t_a_m_p] + The value is interpreted as a format string for strftime(3), using + gmtime(3), producing the formatted timestamp.

This modifier + changes the separator to the character _c. If _c is omitted, no + separator is used. The common escapes (including octal numeric + codes) work as expected. + + ::ttuu Converts the value to upper-case letters. + + ::ttWW Causes subsequent modifiers to treat the value as a single word + (possibly containing embedded whitespace). See also `::[[**]]'. + + ::ttww Causes the value to be treated as a list of words. See also `::[[@@]]'. + + ::SS/_o_l_d___s_t_r_i_n_g/_n_e_w___s_t_r_i_n_g/[11ggWW] + Modifies the first occurrence of _o_l_d___s_t_r_i_n_g in each word of the + value, replacing it with _n_e_w___s_t_r_i_n_g. If a `g' is appended to the + last delimiter of the pattern, all occurrences in each word are + replaced. If a `1' is appended to the last delimiter of the + pattern, only the first occurrence is affected. If a `W' is + appended to the last delimiter of the pattern, the value is treated + as a single word. If _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 (`$'), it is anchored at the end of each + word. Inside _n_e_w___s_t_r_i_n_g, an ampersand (`&') is replaced by + _o_l_d___s_t_r_i_n_g (without the anchoring `^' or `$'). Any character may be + used as the delimiter for the parts of the modifier string. The + anchoring, ampersand and delimiter characters can be escaped with a + backslash (`\'). + + Both _o_l_d___s_t_r_i_n_g and _n_e_w___s_t_r_i_n_g may contain nested expressions.

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 whitespace). + + 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 with its last path component (basename). + + ::uu Removes 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 ..iiff + conditional 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, of course, usually contains + variable expansions. A common error is trying to use expressions + like + ${NUMBERS:M42:?match:no} + which actually tests defined(NUMBERS). To determine if any words + match "42", you need to use something like: + ${"${NUMBERS:M42}" != "":?match:no}. + + ::_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 substitution.

Numeric comparisons + may also use the operators `<<', `<<==', `>>' and `>>=='. + + If the comparison has neither a comparison operator nor a right side, the + expression evaluates to true if it is nonempty and its numeric value (if + any) is not zero. + + When bbmmaakkee is evaluating one of these conditional expressions, and it + encounters a (whitespace-separated) word it doesn't recognize, either the + "make" or "defined" function is applied to it, depending on the form of + the conditional. If the form is `..iiffddeeff', `..iiffnnddeeff' or `..iiff', the + "defined" function is applied. Similarly, if the form is `..iiffmmaakkee' or + `..iiffnnmmaakkee', the "make" function is applied. + + If the conditional evaluates to true, parsing of the makefile continues + as before. If it evaluates to false, the following lines until the + corresponding `..eelliiff' variant, `..eellssee' or `..eennddiiff' are skipped. + + FFoorr llooooppss + 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 + <_m_a_k_e_-_l_i_n_e_s> + ..eennddffoorr + + The _e_x_p_r_e_s_s_i_o_n is expanded and then split into words. On each iteration + of the loop, one word is taken and assigned to each _v_a_r_i_a_b_l_e, in order, + and these _v_a_r_i_a_b_l_e_s are substituted into the _m_a_k_e_-_l_i_n_e_s inside the body + of the for loop. The number of words must come out even; that is, if + there are three iteration variables, the number of words provided must be + a multiple of three. + + If `..bbrreeaakk' is encountered within a ..ffoorr loop, it causes early + termination of the loop, otherwise a parse error. + + OOtthheerr ddiirreeccttiivveess + ..uunnddeeff _v_a_r_i_a_b_l_e ... + Un-define the specified global variables.

The _._P_A_T_H 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.

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 FFRRCC has been used to FoRCe rebuilding + (since the target/dependency does not exist ... unless someone creates an + _F_R_C file). + +BBUUGGSS + The make syntax is difficult to parse. For instance, finding the end of + a variable's use should involve scanning each of the modifiers, using the + correct terminator for each field. In many places make just counts {} + and () in order to find the end of a variable expansion. + + There is no way of escaping a space character in a filename. + + In jobs mode, when a target fails; make will put an error token into the + job token pool. This will cause all other instances of make using that + token pool to abort the build and exit with error code 6. Sometimes the + attempt to suppress a cascade of unnecessary errors, can result in a + seemingly unexplained `*** Error code 6' + +FreeBSD 13.2-RELEASE-p10 March 9, 2024 FreeBSD 13.2-RELEASE-p10 diff --git a/buf.c b/buf.c index fdc6c8ec2b60..8f4de0c3e2bc 100644 --- a/buf.c +++ b/buf.c @@ -1,216 +1,189 @@ -/* $NetBSD: buf.c,v 1.57 2023/12/19 19:33:39 rillig Exp $ */ +/* $NetBSD: buf.c,v 1.58 2024/04/28 15:10:19 rillig Exp $ */ /* * Copyright (c) 1988, 1989, 1990 The Regents of the University of California. * All rights reserved. * * 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.

All commands for a target are * written into a single file, which is then given to the shell to execute * the commands from it. The commands are written to the file using a few * templates for echo control and error control. * * The name of the shell is the basename for the predefined shells, such as * "sh", "csh", "bash". For custom shells, it is the full pathname, and its * basename is used to select the type of shell; the longest match wins. * So /usr/pkg/bin/bash has type sh, /usr/local/bin/tcsh has type csh. * * The echoing of command lines is controlled using hasEchoCtl, echoOff, * echoOn, noPrint and noPrintLen. When echoOff is executed by the shell, it * still outputs something, but this something is not interesting, therefore * it is filtered out using noPrint and noPrintLen. * * The error checking for individual commands is controlled using hasErrCtl, * errOn, errOff and runChkTmpl. * * In case a shell doesn't have error control, echoTmpl is a printf template * for echoing the command, should echoing be on; runIgnTmpl is another * printf template for executing the command while ignoring the return * status. Finally runChkTmpl is a printf template for running the command and * causing the shell to exit on error. If any of these strings are empty when * hasErrCtl is false, the command will be executed anyway as is, and if it * causes an error, so be it. Any templates set up to echo the command will * escape any '$ ` \ "' characters in the command string to avoid unwanted * shell code injection, the escaped command is safe to use in double quotes. * * The command-line flags "echo" and "exit" also control the behavior. The * "echo" flag causes the shell to start echoing commands right away. The * "exit" flag causes the shell to exit when an error is detected in one of * the commands. */ typedef struct Shell { /* * The name of the shell.

This allows a Makefile which has no need of 'dirdeps' to set .MAIN for itself and "just work". 2024-02-18 Simon J Gerraty * bsd.*.mk: for makefiles that get a bsd. symlink, use _this in multiple inclusion tags since .PARSEFILE will not DTRT when such a makefile is included directly by Makefile and automatically (without bsd. prefix). Since we cannot guarantee that our sys.mk will be used, we provide a default _this in each makefile that gets a bsd. prefix such that the value is the same regardless of bsd. prefix. * subdir.mk: drop the !target guard on $SUBDIR_TARGETS 2024-02-12 Simon J Gerraty * install-mk (MK_VERSION): 20240212 * SPDX-License-Identifier: BSD-2-Clause Add SPDX-License-Identifier to inidicate that I consider my copyright on any of these makefiles equivalent to BSD-2-Clause * autoconf.mk: allow for configure.ac as currently recommended * subdir.mk: support @auto which is replaced with each subdir that has a [Mm]akefile. * subdir.mk: include local.subdir.mk if it exists. * subdir.mk: rework to handle .WAIT 2024-02-11 Simon J Gerraty * subdir.mk: _SUBDIRUSE report the target we are entering subdirs for. 2024-02-10 Simon J Gerraty * prog.mk: treat empty SRCS the same as undefined 2024-02-02 Simon J Gerraty * Avoid undefined errors in lint (-dL) mode * man.mk (CMT2DOC_FLAGS): note that -mm does mdoc(7) 2024-01-28 Simon J Gerraty * install-mk (MK_VERSION): 20240128 * FILES: add ccm.dep.mk for C++ modules add suffixes.mk for common location for generic SUFFIX rules. * auto.dep.mk autodep.mk meta.autodep.mk: include ccm.dep.mk replace OBJ_EXTENSIONS with OBJ_SUFFIXES * autodep.mk: leverage CXX_SUFFIXES for __depsrcs and update style (spaces around = etc) * init.mk: add OBJS_SRCS_FILTER to filter SRCS when setting OBJS * meta2deps.py: handle multiple ./ embedded in path better. 2024-01-05 Simon J Gerraty * install-mk (MK_VERSION): 20240105 * dirdeps.mk: for MAKE_VERSION 20240105 we do not have the same limits on command line length, so skip export of lists to env. 2023-12-24 Simon J Gerraty * man.mk: add logic for staging man pages 2023-11-28 Simon J Gerraty * jobs.mk: avoid C suffix in JOB_MAX_C if factor is floating point. This keeps JOB_MAX numeric incase another makefile does comparisons. 2023-11-04 Simon J Gerraty * dpadd.mk: add support for DPLIBS_QUALIFIER_LIST * gendirdeps.mk: if META_XTRAS is passed to us, add to META_FILES 2023-10-03 Simon J Gerraty * compiler.mk (COMPILER_VERSION): clang at least is into double digit major versions. 2023-10-02 Simon J Gerraty * install-mk (MK_VERSION): 20231001 * set _CCLINK in init.mk so lib.mk can use it for default SHLIB_LD * lib.mk (cleanlib): use LD_solink so we remove all the right files. Use -Wl for -soname since we now default to linking with CC We should not need SHLIB_LDSTARTFILE or SHLIB_LDENDFILE when linking with CC. 2023-09-24 Simon J Gerraty * init.mk (QUALIFIED_VAR_LIST): Add SRCS 2023-09-09 Simon J Gerraty * jobs.mk (JOB_MAX): use -jC if we can we actually use JOB_MAX_C which defaults to 1.33C 2023-08-18 Simon J Gerraty * now_utc: %s only works with :localtime 2023-07-14 Simon J Gerraty * install-sh: ignore -c as claimed and only insist on a directory for destination when more than one file to copy. * sys.mk: when looking for SYS_OS_MK try ${.MAKE.OS} and ${.MAKE.OS:S,64,,} early (so we find sys/IRIX.mk for IRIX64) 2023-07-13 Simon J Gerraty * install-mk (MK_VERSION): 20230711 * sys.mk: set SYS_MK and INSTALL_SH for systems with incompatible install(1) * sys/IRIX.mk: when setting ROOT_GROUP only match the first :0: set INSTALL to install-sh rather than pathname that may not exist (yet). 2023-07-07 Simon J Gerraty * dirdeps.mk: pass DIRDEP_TARGETS to DIRDEP_MAKE normally this is empty - for the default target, but there are use-cases where we might set it to something else. 2023-07-04 Simon J Gerraty * install-mk (MK_VERSION): 20230704 * dirdeps.mk: apply DEBUG_DIRDEPS_LIST_FILTER to lists we output when DEBUG_DIRDEPS is in effect. Eg. DEBUG_DIRDEPS_LIST_FILTER=ts\n can greatly improve readability. 2023-05-25 Simon J Gerraty * meta.autodep.mk (beforegendirdeps): allow tasks to be done at END but before gendirdeps 2023-05-22 Simon J Gerraty * install-mk (MK_VERSION): 20230522 * host-target.mk: deal with garbage from uname -m on Darwin ppc, also NetBSD appears to use x86_64 for MACHINE_ARCH these days so just leave it be. For Darwin arm and i386 use _HOST_MACHINE for _HOST_ARCH so we get arm64 and x86_64 in HOST_TARGET. 2023-05-15 Simon J Gerraty * sys.vars.mk: M_mtime use :mtime or 'stat -f %m' for older versions of bmake. * dirdeps.mk (TARGET_SPEC_VARS.host): While *most* projects need only DEP_MACHINE for host, there is always an exception. So we allow for TARGET_SPEC_VARS.host to be a subset of TARGET_SPEC_VARS. The default will *just work* for most projects. We set DEP_TARGET_SPEC_VARS and hence DEP_TARGET_SPEC based on DEP_MACHINE. Allow for M_dep_qual_fixes.host to be different too and take care to apply the right set. 2023-05-14 Simon J Gerraty * sys.dirdeps.mk: we *do* want to override OBJTOP and if MAKEOBJDIR was not in env as we want it; put it there - carefully. Ensure OBJROOT ends in / or - (/ preferred) Add more comments to explain what/why. 2023-05-13 Simon J Gerraty * install-mk (MK_VERSION): 20230512 * dirdeps.mk: take care not to qualify "host" dirdeps * sys.dirdeps.mk (OBJTOP): must use ?= 2023-05-10 Simon J Gerraty * meta.autodep.mk: if LOCAL_DEPENDS_GUARD is "no" suppress processing of .depend 2023-05-09 Simon J Gerraty * dirdeps.mk: do not add _CURDIR to DIRDEPS for SRCTOP * meta.sys.mk sys.dirdeps.mk: originally DIRDEPS_BUILD and META_MODE were the same thing, but META_MODE is useful by itself. Move things from meta.sys.mk which actually pertain to DIRDEPS_BUILD to sys.dirdeps.mk 2023-05-04 Simon J Gerraty * install-mk (MK_VERSION): 20230504 May the Forth be with you * dirdeps.mk: as with meta.sys.mk we treat "host" as special. DEP_TARGET_SPEC is just ${DEP_MACHINE} * meta.sys.mk: ensure DEP_* for TARGET_SPEC_VARS are set at level > 0 since these are often refered to in Makefile.depend* 2023-04-26 Simon J Gerraty * jobs.mk: report ${.TARGET} ${JOB_ARGS} ${JOB_LOG} and anything in ${JOB_LOG_START} * jobs.mk: look for newlog.sh in ${.SYSPATH:U${.PARSEDIR}} or a scripts subdir before searching $PATH. * FILES: include newlog.sh for jobs.mk 2023-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20230420 * lib.mk: include LDFLAGS and LDADD when linking shared libs * gendirdeps.mk: document setting GENDIRDEPS_FILTER_VARS etc via local.meta.sys.mk rather than local.gendirdeps.mk so DEP_* variables can be set at level 1+ to avoid syntax errors when used in conditionals in manually maintained Makefile.depend files. * dirdeps.mk: ensure M_dep_qual_fixes is applied to all _machines 2023-04-18 Simon J Gerraty * dirdeps.mk: check we were not included by Makefile.depend.options as the result is bad. 2023-04-14 Simon J Gerraty * install-mk (MK_VERSION): 20230414 * meta.sys.mk: since we have :range we can put the logic for processing TARGET_SPEC from env here. * dirdeps.mk: reset DIRDEPS and DEP_RELDIR before including local.dirdeps-missing.mk, also improve debug output. * dirdeps.mk: to allow make -f dirdeps.mk include.$TARGET_SPEC we need to use :M*[/.]* same as for when actually setting DIRDEPS from the targets on command line. 2023-04-12 Simon J Gerraty * Add jobs.mk 2023-03-21 Simon J Gerraty * install-mk (MK_VERSION): 20230321 * meta.stage.mk: allow STAGE_SHLIB_LINKS_FILTER to filter STAGE_LIBS for SHLIB_LINKS. * autoconf.mk: add .WAIT after config.status 2023-02-17 Simon J Gerraty * sys.vars.mk: add M_Index to report the index of a word in a list. 2023-02-15 Simon J Gerraty * install-mk (MK_VERSION): 20230215 * warnings.mk: allow better control of -Werror allow -Wno-error or similar to be added if WARNINGS_SET < WERROR_SET account for COMPILER_TYPE 2023-01-29 Simon J Gerraty * autoconf.mk: hook config.status to beforebuild. * whats.mk: what*.c is NOTMAIN 2023-01-27 Simon J Gerraty * install-mk (MK_VERSION): 20230127 control umask so directories are created with suitable mode. 2023-01-20 Simon J Gerraty * install-mk (MK_VERSION): 20230120 * sys.vars.mk: add M_On and M_Onr also cleanup to be more consistent wrt testing MAKE_VERSION 2023-01-12 Simon J Gerraty * install-mk (MK_VERSION): 20230112 * meta2deps.{py,sh}: assert if filemon data is truncated we should see the '# Bye bye' record - assert if we do not. 2022-09-09 Simon J Gerraty * install-mk (MK_VERSION): 20220909 * sys/Linux.mk set EGREP to grep -E to avoid deprecation warnings 2022-09-06 Simon J Gerraty * dirdeps-options.mk: explain the need to use ${DEP_${TARGET_SPEC_VAR}:U${TARGET_SPEC_VAR}} when refering to ${TARGET_SPEC_VAR} 2022-09-03 Simon J Gerraty * install-mk (MK_VERSION): 20220903 * M_cmpv handle more than 3 dots and clear leading 0's 2022-07-20 Simon J Gerraty * install-mk (MK_VERSION): 20220720 * prog.mk: handle PROG_CXX for more than just NetBSD 2022-06-20 Simon J Gerraty * install-mk (MK_VERSION): 20220620 * yacc.mk: when we have *.y in SRCS used explicit rules and .ORDER rather than just suffix rules 2022-04-23 Simon J Gerraty * install-mk (MK_VERSION): 20220422 * gendirdeps.mk: If LOCAL_DEPENDS_GUARD is set to "no" do not capture any local depends in Makefile.depend 2022-03-25 Simon J Gerraty * install-mk (MK_VERSION): 20220323 * posix.mk: default rules for .POSIX: 2022-03-17 Simon J Gerraty * sys/*.mk: remove l from ARFLAGS 2022-03-14 Simon J Gerraty * install-mk (MK_VERSION): 20220314 * dirdeps-options.mk: allow options to be per RELDIR try DIRDEPS_OPTIONS_QUALIFIER_LIST first prefixed with ${DEP_RELDIR}. 2022-02-14 Simon J Gerraty * install-mk (MK_VERSION): 20220214 * cc-wrap.mk: fix :@ modifier 2022-02-06 Simon J Gerraty * install-mk (MK_VERSION): 20220206 * cc-wrap.mk: docuement how CCACHE etc might be set for maximum flexibility 2022-02-05 Simon J Gerraty * sys.vars.mk: use JOT_CMD (jot or seq) if available for M_JOT 2022-02-04 Simon J Gerraty * install-mk (MK_VERSION): 20220204 * host-target.mk: use .MAKE.OS if available 2022-02-02 Simon J Gerraty * install-mk (MK_VERSION): 20220202 * cc-wrap.mk: allow other entries in CC_WRAP_FILTER We add our filter on extensions last, so prior filters can apply to the whole value of .IMPSRC 2022-02-01 Simon J Gerraty * cc-wrap.mk: take advantage of target local variables to wrap compilers like CC CXX with wrappers like ccache distcc etc 2022-01-28 Simon J Gerraty * meta2deps: we do not expect any trace data for setid apps 2022-01-26 Simon J Gerraty * dirdeps.mk: ensure TARGET_SPEC and TARGET_SPEC_VARS are passed to sub-make using DIRDEPS_CACHE 2022-01-07 Simon J Gerraty * dirdeps.mk: use _cache_script to minimize the number of shells forked when generating dirdeps.cache 2022-01-02 Simon J Gerraty * install-mk (MK_VERSION): 20220101 * dirdeps.mk: initialize DEP_* and _debug_reldir earlier. If initial DIRDEPS are from command line, create the target _dirdeps_cmdline as an indication. 2022-01-01 Simon J Gerraty * init.mk (_SKIP_BUILD): when doing DIRDEPS_BUILD at top-level only some targets are allowed at level 0, for leaf makefiles only the default (all) target is restricted 2021-12-28 Simon J Gerraty * install-mk (MK_VERSION): 20211228 * meta2deps.py: filemon on Linux is not as reliable as we might like, we do not want to update DIRDEPS if filemon output is incomplete. Track pids that we 'E'xec and make sure we see an e'X'it for each one. Throw an error if we are missing any 'X' records. 2021-12-12 Simon J Gerraty * sys.mk: simplify; include meta.sys.mk if MK_META_MODE is yes. * meta.sys.mk: do not check for /dev/filemon if .MAKE.PATH_FILEMON is something else. * meta.autodep.mk: we can now reference ${.SUFFIXES} * meta2deps.py: derive a list of dirdep extensions from TARGET_SPEC to trim from dirdeps. * dirdeps.mk: flip the computation of qualified vs unqualified dirdeps - it is much simpler to check for unqualified first. 2021-12-11 Simon J Gerraty * install-mk (MK_VERSION): 20211212 * auto.dep.mk: rearrange so that the trivial implementation for recent bmake is more obvious. 2021-12-07 Simon J Gerraty * install-mk (MK_VERSION): 20211207 * Ensure guard targets are .NOTMAIN * meta.sys.mk: check for nofilemon support when we skip level 0 * auto.dep.mk: make this usable in meta mode for platforms that cannot use meta.autodep.mk * meta2deps.py: avoid confusion if MACHINE and another TARGET_SPEC_VAR have same value. 2021-11-27 Simon J Gerraty * dirdeps.mk: when building dirdeps.cache, minimize the amount of data put into env, by stripping ${SRCTOP}/ from each entry. A long sandbox name can double the amount of memory consumed and in extreme cases cause failure. While we are at it, strip ${SRCTOP}/ from a lot of the debug output. 2021-11-11 Simon J Gerraty * install-mk (MK_VERSION): 20211111 * meta.stage.mk (LN_CP_SCRIPT): if staging to NFS cp -p can fail so fallback to cp if necessary. 2021-10-30 Simon J Gerraty * man.mk (CMT2DOC): use cmt2doc.py rather than the 30 year old cmt2doc.pl 2021-10-24 Simon J Gerraty * meta.stage.mk: stage_as_and_symlink use ${STAGE_LINK_AS_$f:U$f} as the symlink (rare) 2021-10-16 Simon J Gerraty * autoconf.mk: if AUTOCONF_GENERATED_MAKEFILE is set and has not been read, throw an error after running configure telling user to restart. 2021-10-13 Simon J Gerraty * install-mk (MK_VERSION): 20211011 * Add support for SCO_SV 2021-10-01 Simon J Gerraty * install-mk (MK_VERSION): 20211001 * man.mk: use MAN_SUFFIXES and CMT2DOC_SUFFIXES for more flexibility 2021-09-13 Simon J Gerraty * options.mk (describe-options): print options and their values and optional description 2021-09-11 Simon J Gerraty * install-mk (MK_VERSION): 20210911 * options.mk (show-options): print options and their values 2021-09-08 Simon J Gerraty * install-mk (MK_VERSION): 20210909 * lib.mk: apply patch from to fix shared libs on Linux 2021-08-08 Simon J Gerraty * install-mk (MK_VERSION): 20210808 * options.mk: issue warning for WITH_*=no 2021-06-16 Simon J Gerraty * install-mk (MK_VERSION): 20210616 * dirdeps.mk: when using .MAKE.DEPENDFILE_PREFERENCE to find depend files to read, anchor MACHINE at , or end of string to avoid prefix match. 2021-05-04 Simon J Gerraty * install-mk (MK_VERSION): 20210504 * dirdeps.mk: re-implement ALL_MACHINES support to better cater for local complexities, when ONLY_TARGET_SPEC_LIST is not set. local.dirdeps.mk can set DIRDEPS_ALL_MACHINES_FILTER and/or DIRDEPS_ALL_MACHINES_FILTER_XTRAS to filter the results we get from listing all existing Makefile.depend.* 2021-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20210420 * dirdeps.mk: revert previous - not always safe. 2021-03-20 Simon J Gerraty * install-mk (MK_VERSION): 20210321 * dirdeps.mk: when generating dirdeps.cache we only need to hook the initial DIRDEPS to the dirdeps target. That and any _build_xtra_dirs (like tests which should not be hooked directly to the dependency graph - to avoid cycles) 2021-01-30 Simon J Gerraty * install-mk (MK_VERSION): 20210130 * dirdeps.mk: expr 2 - 1 - 1 exits with a bad status we need to guard against this in DIRDEP_LOADAVG_REPORT. * dirdeps.mk: restore respect for TARGET_MACHINE 2021-01-06 Simon J Gerraty * install-mk (MK_VERSION): 20210101 * dirdeps.mk: first time we are read, just use TARGET_SPEC for _DEP_TARGET_SPEC 2020-12-22 Simon J Gerraty * sys.mk (MAKE_SHELL): use ${.SHELL:Ush} and use := when setting SHELL 2020-12-21 Simon J Gerraty * install-mk (MK_VERSION): 20201221 * dirdeps-options.mk: latest bmake allows only one arg to .undef 2020-12-11 Simon J Gerraty * dirdeps-targets.mk: allow for "." in DIRDEPS_TARGETS_DIRS so that any directory can be treated as a target. 2020-11-26 Simon J Gerraty * install-mk (MK_VERSION): 20201126 * own.mk: use .MAKE.{UID,GID} if available. * init.mk: suppress _SKIP_BUILD warning if doing -V 2020-11-20 Simon J Gerraty * install-mk (MK_VERSION): 20201120 * init.mk: rename LEVEL0_TARGETS to DIRDEPS_BUILD_LEVEL0_TARGETS * dirdeps-targets.mk: fix typo in comment 2020-11-06 Simon J Gerraty * install-mk (MK_VERSION): 20201106 * meta.autodep.mk: use OBJ_EXTENSIONS rather than hardcode sed args to tweak extensions for local deps. 2020-11-01 Simon J Gerraty * install-mk (MK_VERSION): 20201101 * dirdeps.mk: most leaf makefiles are not suitable for building dirdeps.cache so if RELDIR is not "." use dirdeps.mk 2020-10-28 Simon J Gerraty * install-mk (MK_VERSION): 20201028 * dirdeps.mk: if we don't have :range use equivalent of M_RANGE when building dirdeps.cache for leaf directory use -f dirdeps.mk * sys.vars.mk: add M_JOT and M_RANGE 2020-10-01 Simon J Gerraty * install-mk (MK_VERSION): 20201001 * meta2deps.{py,sh}: throw an error if we don't see filemon version 2020-09-09 Simon J Gerraty * install-mk (MK_VERSION): 20200909 * dirdeps-cache-update.mk: use cache_update_dirdep as guard target 2020-08-26 Simon J Gerraty * dirdeps.mk: ensure we cannot confuse a static cache for dynamic (even more rare that use of static cache is playing clever tricks with it) 2020-08-16 Simon J Gerraty * dirdeps-cache-update.mk: allow MK_STATIC_DIRDEPS_CACHE_UPDATE_IMMEDIATE to control when we actually update STATIC_DIRDEPS_CACHE. * stage-install.sh: create dest directory if needed before running install(1) 2020-08-10 Simon J Gerraty * dirdeps-targets.mk: include Makefile.dirdeps.options * dirdeps.mk: use _TARGETS if defined for DIRDEPS_CACHE 2020-08-09 Simon J Gerraty * dirdeps.mk: default BUILD_DIRDEPS_MAKEFILE to empty * dirdeps-cache-update.mk: building parallel cache update under the context of dirdeps-cached would be ideal, but is problematic, so it runs as a sibling. Use cache-built target to ensure we wait for it to complete if necessary. 2020-08-06 Simon J Gerraty * install-mk (MK_VERSION): 20200806 * dirdeps-options: allow TARGET_SPEC to affect option values. Use DIRDEPS_OPTIONS_QUALIFIER_LIST before using bare MK_* * dirdeps-targets.mk: check for MK_STATIC_DIRDEPS_CACHE defined before looking for STATIC_DIRDEPS_CACHE 2020-08-05 Simon J Gerraty * host-target.mk: Darwin use MACHINE for HOST_ARCH too * dirdeps-options.mk: improve debug output 2020-07-22 Simon J Gerraty * dirdeps.mk: set and export DYNAMIC_DIRDEPS_CACHE for use by dirdeps-cache-update.mk * dirdeps-targets.mk: set and export STATIC_DIRDEPS_CACHE for use by dirdeps-cache-update.mk even if we don't use it. * dirdeps-cache-update.mk: we only need worry about the background update case, with the above, the update from DIRDEPS_CACHE is simple. * meta2deps.py: R 1234 . is not interesting 2020-07-20 Simon J Gerraty * sys.mk: default MK_STATIC_DIRDEPS_CACHE from MK_DIRDEPS_CACHE * dirdeps-options.mk: do not :tu DIRDEPS_OPTIONS allows use of lower case for pseudo options. * dirdeps-cache-update.mk: magic to deal with STATIC_DIRDEPS_CACHE 2020-07-18 Simon J Gerraty * dirdeps-targets.mk: Look for Makefile.dirdeps.cache which allows us to have a static cache for expensive targets. Use -DWITHOUT_STATIC_DIRDEPS_CACHE -DWITH_DIRDEPS_CACHE to regenerate the dirdeps.cache it is a copy of. 2020-07-17 Simon J Gerraty * Get rid of BUILD_AT_LEVEL0, MK_DIRDEPS_BUILD makes more sense. 2020-07-16 Simon J Gerraty * dirdeps.mk (DIRDEP_LOADAVG_REPORT): make it easy to record load averages at intervals during build. 2020-07-15 Simon J Gerraty * install-mk (MK_VERSION): 20200715 * dirdeps.mk: tweak Checking line to make matching Finished lines for post-build analysis easier. * meta.autodep.mk: use !defined(WITHOUT_META_STATS) * progs.mk: avoid prog.mk outputting multiple Finished lines 2020-07-11 Simon J Gerraty * dirdeps.mk: further optimize dirdeps.cache generate a DIRDEPS.${.TARGET} list for other purposes and improve the layout. 2020-07-10 Simon J Gerraty * dirdeps.mk: optimize content of dirdeps.cache 2020-06-28 Simon J Gerraty * sys/*.mk: make it easier for local*sys.mk to customize by using ?= 2020-06-22 Simon J Gerraty * gendirdeps.mk (LOCAL_DEPENDS_GUARD): if we don't build at level 0 it is much safer to guard local depends with a simple check for .MAKE.LEVEL > 0 2020-06-10 Simon J Gerraty * install-mk (MK_VERSION): 20200610 * mkopt.sh: this needs posix shell so #!/bin/sh should be ok 2020-06-06 Simon J Gerraty * install-mk (MK_VERSION): 20200606 * dirdeps-targets.mk: allow for filtering of .TARGETS * meta2deps.py: fix bug in processing 'L'ink and 'M'ove entries - and we don't care about 'W'rite entries. Also ignore absolute paths that do not exist. 2020-05-25 Simon J Gerraty * install-mk (MK_VERSION): 20200525 * init.mk: expand and simplify handling of qualified vars like CPPFLAGS.${.TARGET:T} 2020-05-15 Simon J Gerraty * install-mk (MK_VERSION): 20200515 * dirdeps.mk: set _debug_* earlier and allow passing -d* flags to submake when building DIRDEPS_CACHE 2020-05-09 Simon J Gerraty * whats.mk: more easily extensible 2020-05-02 Simon J Gerraty * whats.mk: greatly simplify by adding what.c to SRCS 2020-05-01 Simon J Gerraty * whats.mk: for libs take care how we add to *OBJS * lib.mk: : works better with whats.mk 2020-04-25 Simon J Gerraty * install-mk (MK_VERSION): 20200420 * meta.stage.mk: it is not a STAGE_CONFLICT if some-target.dirdep contains the same ${RELDIR} and a prefix match for our ${TARGET_SPEC} 2020-04-16 Simon J Gerraty * install-mk (MK_VERSION): 20200416 * sys/*.mk: set MAKE_SHELL rather than SHELL so as not to interfere with user env. * sys.mk: default MAKE_SHELL to sh and SHELL to MAKE_SHELL * autodep.mk: use MAKE_SHELL. 2019-11-21 Simon J Gerraty * gendirdeps.mk: clear .SUFFIXES to avoid a lot of wasted effort, and unexport _meta_files when no longer needed as it consumes space we need for command line. 2019-11-11 Simon J Gerraty * dirdeps.mk _DIRDEP_USE: use DIRDEP_DIR and add DIRDEP_USE_PRELUDE at start - facilitates job distribution 2019-10-04 Simon J Gerraty * dirdeps-targets.mk: Use TARGET_SPEC_LAST_LIST defaults to ${${TARGET_SPEC_VARS:[-1]}_LIST} to match valid TARGET_SPEC qualified depend files. 2019-10-02 Simon J Gerraty * dirdeps-targets.mk: encapsulate logic for finding top-level targets to set initial DIRDEPS for DIRDEPS_BUILD 2019-09-27 Simon J Gerraty * install-mk (MK_VERSION): 20190911 * compiler.mk: set COMPILER_TYPE 2019-07-17 Simon J Gerraty * install-mk (MK_VERSION): 20190704 * sys/Darwin.mk: support for Objective-C and clang 2019-05-30 Simon J Gerraty * dirdeps.mk: avoid insanely long command line when generating cache 2019-05-23 Simon J Gerraty * install-mk (MK_VERSION): 20190505 * whats.mk: handle corner case SHLIB defined but not LIB 2018-09-19 Simon J Gerraty * install-mk (MK_VERSION): 20180919 * dirdeps-options.mk: .undef cannot handle var that expands to more than one var. 2018-07-08 Simon J Gerraty * meta.stage.mk: allow wildcards in STAGE_FILES.* etc. 2018-06-01 Simon J Gerraty * meta.autodep.mk: export META_FILES to avoid command line limit * gendirdeps.mk: if we have lots of .meta files put them in an @list 2018-05-28 Simon J Gerraty * dirdeps-options.mk: use local.dirdeps-options.mk not local.dirdeps-option.mk 2018-04-20 Simon J Gerraty * install-mk (MK_VERSION): 20180420 * dirdeps.mk: include local.dirdeps-build.mk when .MAKE.LEVEL > 0 ie. we are building something. 2018-04-14 Simon J Gerraty * FILES: add dirdeps-options.mk to deal with optional DIRDEPS. 2018-04-05 Simon J Gerraty * install-mk (MK_VERSION): 20180405 * ldorder.mk: describe how to use LDORDER_EXTERN_BARRIER if needed. 2018-01-18 Simon J Gerraty * install-mk (MK_VERSION): 20180118 * ldorder.mk: let make compute correct link order 2017-12-12 Simon J Gerraty * install-mk (MK_VERSION): 20171212 * gendirdeps.mk: guard against bogus entries in GENDIRDEPS_FILTER 2017-11-14 Simon J.

Gerraty * install-mk (MK_VERSION): 20171018 * whats.mk: include what_thing in what_uuid to avoid problem when building multiple apps in the same directory. 2017-08-12 Simon J. Gerraty * install-mk (MK_VERSION): 20170812 * autoconf.mk: Use CONFIGURE_DEPS so Makefile can add dependencies for config.recheck and config.gen 2017-06-30 Simon J. Gerraty * install-mk (MK_VERSION): 20170630 * meta.stage.mk: avoid triggering stage_* targets with nothing to do. 2017-05-23 Simon J. Gerraty * meta2deps.py: take special care of '..' 2017-05-15 Simon J. Gerraty * install-mk (MK_VERSION): 20170515 * dirdeps.mk (DEP_EXPORT_VARS): on rare occasions it is useful/necessary for a Makefile.depend file to export some knobs. This is complicated when we are doing DIRDEPS_CACHE, so we will handle export of any variables listed in DEP_EXPORT_VARS. 2017-05-08 Simon J. Gerraty * install-mk (MK_VERSION): 20170505 * meta2deps.py: fix botched indenation. 2017-05-05 Simon J. Gerraty * sys/*.mk: Remove setting of MAKE it is unnecessary and in many cases wrong (basname rather than full path) * scripts.mk (SCRIPTSGROUPS): make this more like files.mk and inc.mk * init.mk: define realbuild to simplify logic in {lib,prog}.mk etc 2017-05-01 Simon J.

Gerraty * install-mk (MK_VERSION): 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 * 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.

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): 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): 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 * 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 * install-mk (MK_VERSION): 20150615 * auto.obj.mk: allow use of MAKEOBJDIRPREFIX too. Follow make's normal precedence rules. * gendirdeps.mk: allow customization of the header. eg. for FreeBSD: GENDIRDEPS_HEADER= echo '\# ${FreeBSD:L:@v@$$$v$$ @:M*F*}'; * meta.autodep.mk: ignore dirdeps.cache* * meta.stage.mk: when bootstrapping options it can be handy to throw warnings rather than errors for staging conflicts. * meta.sys.mk: include local.meta.sys.mk for customization 2015-06-06 Simon J. Gerraty * install-mk (MK_VERSION): 20150606 * dirdeps.mk: don't rely on manually maintained Makefile.depend to set DEP_RELDIR and reset DIRDEPS. By setting DEP_RELDIR ourselves we can skip :tA * gendirdeps.mk: skip setting DEP_RELDIR. 2015-05-24 Simon J. Gerraty * dirdeps.mk: avoid wildcards like make(bootstrap*) 2015-05-20 Simon J. Gerraty * install-mk (MK_VERSION): 20150520 * dirdeps.mk: when we are building dirdeps cache file we *want* meta_oodate to look at all the Makefile.depend files, so set .MAKE.DEPENDFILE to something that won't match. * meta.stage.mk: for STAGE_AS_* basename of file may not be unique so first use absolute path as key. Also skip staging at level 0. 2015-04-30 Simon J. Gerraty * install-mk (MK_VERSION): 20150430 * dirdeps.mk: fix _count_dirdeps for non-cache case. 2015-04-16 Simon J. Gerraty * install-mk (MK_VERSION): 20150411 bump version * own.mk: put AUTO_OBJ in OPTIONS_DEFAULT_NO rather than YES. it is here mainly for documentation purposes, since if using auto.obj.mk it is better done via sys.mk 2015-04-01 Simon J. Gerraty * install-mk (MK_VERSION): 20150401 * meta2deps.sh: support @list * meta2deps.py: updates from Juniper o add EXCLUDES o skip bogus input files. o treat 'M' and 'L' as both an 'R' and a 'W' 2015-03-03 Simon J. Gerraty * install-mk (MK_VERSION): 20150303 * dirdeps.mk: if MK_DIRDEPS_CACHE is yes, use dirdeps-cache which is built via sub-make so we have a .meta file to tell if it is out-of-date. The dirdeps-cache contains the same dependency rules that we normaly construct on the fly. This adds a few seconds overhead when the cache is out of date, but for a large target, the savings can be significant (10-20min). 2014-11-18 Simon J. Gerraty * install-mk (MK_VERSION): 20141118 * meta.stage.mk: add stale_staged * dirdeps.mk (_DIRDEP_USE_LEVEL): allow this to be tweaked only useful under very rare conditions such as FreeBSD's make universe. * auto.obj.mk: Allow MK_AUTO_OBJ to set MKOBJDIRS=auto 2014-11-11 Simon J. Gerraty * install-mk (MK_VERSION): 20141111 * mkopt.sh: use consistent semantics for _mk_opt and _mk_opts 2014-11-09 Simon J. Gerraty * FILES: include mkopt.sh which allows handling options in shell scripts in a manner compatible with options.mk 2014-10-12 Simon J. Gerraty * meta.stage.mk: ensure only _STAGED_DIRS under objroot are used for GENDIRDEPS_FILTER to avoid surprises. 2014-10-10 Simon J. Gerraty * dirdeps.mk (NSkipHostDir): this needs SRCTOP prepended since by the time it is applied to __depdirs they have. * dirdeps.mk fix filtering of _machines since M_dep_qual_fixes expects patterns like *.${MACHINE} * cython.mk (pyprefix?): use pyprefix to find python bits since prefix might be something else (where we install our stuff) 2014-09-11 Simon J. Gerraty * install-mk (MK_VERSION): 20140911 * dirdeps.mk: add bootstrap target to simplify adding support for new MACHINE. 2014-09-01 Simon J. Gerraty * gendirdeps.mk: Add handling of GENDIRDEPS_FILTER_DIR_VARS and GENDIRDEPS_FILTER_VARS to make it easier to produce sharable Makefile.depend files. 2014-08-28 Simon J. Gerraty * install-mk (MK_VERSION): 20140828 * cython.mk: capture logic for building python extension modules with Cython. 2014-08-08 Simon J. Gerraty * meta.stage.mk (_STAGE_AS_BASENAME_USE): Add StageAs variant 2014-08-02 Simon J. Gerraty * install-mk (MK_VERSION): 20140801 * dep.mk: use explicit MKDEP_MK rather than overload MKDEP to identify the autodep.mk variant. * sys.dependfile.mk: delete .MAKE.DEPENDFILE if its initial value does not match .MAKE.DEPENDFILE_PREFIX * meta.autodep.mk: if _bootstrap_dirdeps add RELDIR to DIRDEPS 2014-05-22 Simon J. Gerraty * install-mk (MK_VERSION): 20140522 * lib.mk: use CC to link shlib for linux too patch from Brendan MacDonell 2014-05-05 Simon J. Gerraty * meta.autodep.mk: add _reldir_{finish,failed} for gathering stats if WITH_META_STATS is defined. 2014-05-02 Simon J. Gerraty * dirdeps.mk: accept -DWITHOUT_DIRDEPS (same a as -DNO_DIRDEPS) to supress dirdeps outside of .CURDIR. 2014-04-05 Simon J. Gerraty * Fix spelling errors - patch from Pedro Giffuni 2014-03-14 Simon J. Gerraty * install-mk (MK_VERSION): 20140314 * dirdeps.mk (beforedirdeps): a handy hook * dirdeps.mk (DIRDEP_MAKE): allow the actual command we run to visit leaf dirs to be intercepted (eg. for distributed build). * dirdeps.mk (__depdirs): ensure // don't sneak in * gendirdeps.mk (DIRDEPS): ensure // don't sneak in 2014-02-21 Simon J. Gerraty * rst2htm.mk (RST2PDF): add support for rst2pdf 2014-02-14 Simon J. Gerraty * install-mk (MK_VERSION): bump version * dirdeps.mk (_last_dependfile): use .INCLUDEDFROMFILE if available. 2014-02-10 Simon J. Gerraty * options.mk: avoid :U so this isn't bmake dependent 2014-02-09 Simon J. Gerraty * options.mk: cleanup and simplify semanitcs NO_* dominates all, if both WITH_* and WITHOUT_* are defined then result is DOMINATE_* which defaults to "no". Ie. WITHOUT_ normally wins. 2013-12-12 Simon J. Gerraty * install-mk (MK_VERSION): bump version * meta2deps.py: convert to print function for python3 compat. we also need to open files with mode 'r' rather than 'rb' otherwise we get bytes instead of strings. 2013-10-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version * dirdeps.mk: when TARGET_SPEC_VARS is more than just MACHINE apply the same filtering (M_dep_qual_fixes) when setting _machines as _build_dirs. Also fix the filtering of Makefile.depend files - for reporting what we are looking for (M_dep_qual_fixes can get confused by Makefile.depend) Add some more debug info. 2013-09-04 Simon J. Gerraty * gendirdeps.mk (_objtops): fix typo also while processing M2D_OBJROOTS to gather qualdir_list qualify $ql with loop iterator to ensure correct results. 2013-08-01 Simon J. Gerraty * install-mk (MK_VERSION): 20130801 * libs.mk: update to match progs.mk 2013-07-26 Simon J. Gerraty * install-mk (MK_VERSION): 20130726 some updates from Juniper and FreeBSD o meta2deps.py: indicate file and line number when we hit parse errors also allow @file to provide huge list of .meta files. * meta2deps.py: add try_parse() to cleanup the above. 2013-07-16 Simon J. Gerraty * install-mk (MK_VERSION): 20130716 * own.mk: add GPROG as an option * prog.mk: honor MK_GPROF==yes 2013-05-10 Simon J. Gerraty * install-mk (MK_VERSION): 20130505 * gendirdeps.mk, meta2deps.py, meta2deps.sh: handle $TARGET_SPEC for when $MACHINE isn't enough for objdir distinction. Bring meta2deps.sh closer to par with meta2deps.py. 2013-04-18 Simon J. Gerraty * meta.stage.mk: set INSTALL to STAGE_INSTALL when making 'all' also if the target 'beforeinstall' exists, make it depend on .dirdep (incase it uses STAGE_INSTALL). 2013-04-17 Simon J. Gerraty * install-mk (MK_VERSION): 20130401 ;-) * meta.stage.mk (STAGE_INSTALL_SH): add stage-install.sh as wrapper around install(1). * options.mk (OPTION_PREFIX): Allow a prefix other than MK_ 2013-03-30 Simon J. Gerraty * meta2deps.py (MetaFile.__init__): ensure self.cwd is initialized. * install-mk (MK_VERSION): bump version 2013-03-21 Simon J. Gerraty * install-mk (MK_VERSION): bump version * gendirdeps.mk: do not apply :tA to DPADD entries, since we lose any trailing /., rather apply :tA only when needed. * gendirdeps.mk: better mimic meta2deps handling of .dirdep files. * meta.stage.mk (LN_CP_SCRIPT): Add LnCp to do the ln||cp dance consistently. * dirdeps.mk: better describe the dance in sys.mk for TARGET_SPEC. 2013-03-18 Simon J. Gerraty * gendirdeps.mk: revert the dance around .MAKE.DEPENDFILE_DEFAULT it is simpler to just not update when say building for "host" (where we know we apply filters to DIRDEPS), and using a non-machine qualified dependfile. 2013-03-16 Simon J. Gerraty * dirdeps.mk: improve DIRDEPS filtering by allowing DEP_SKIP_DIR and DEP_DIRDEPS_FILTER to vary by DEP_MACHINE and DEP_TARGET_SPEC * gendirdeps.mk: ensure _objroot has trailing / if it needs it. * meta2deps.py: if machine is "host", then also trim self.host_target from any OBJROOTS. 2013-03-11 Simon J. Gerraty * gendirdeps.mk: if .MAKE.DEPENDFILE_DEFAULT is not machine qualified but _DEPENDFILE is, and .MAKE.DEPENDFILE_DEFAULT exists but _DEPENDFILE does not, compare the new _DEPENDFILE against .MAKE.DEPENDFILE_DEFAULT and discard if the same. 2013-03-08 Simon J. Gerraty * meta.stage.mk: use STAGE_TARGETS to control .ORDER and hook to all: via staging: 2013-03-07 Simon J. Gerraty * sys.dependfile.mk (.MAKE.DEPENDFILE_DEFAULT): use a separate variable for the default .MAKE.DEPENDFILE value so that it can be controlled independently of .MAKE.DEPENDFILE_PREFERENCE * meta.stage.mk: throw error if cp fails etc. Stage*() return early if passed no args. .ORDER stage_* 2013-03-03 Simon J. Gerraty * install-mk (MK_VERSION): bump version * gendirdeps.mk: handle multiple M2D_OBJROOTS better. 2013-02-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20130210 * import latest dirdeps.mk, gendirdeps.mk and meta2deps.py from Juniper. o dirdeps.mk now fully supports TARGET_SPEC consisting of more than just MACHINE. o no longer use DEP_MACHINE from Makefile.depend* so remove it. 2013-01-23 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20130123 * meta.stage.mk: add stage_links (hard links). if doing hard links, we add dest to link as well. Default the stage dir for [sym]links to STAGE_OBJTOP since these are typically specified as absolute paths. Add -m "mode" flag to StageFiles and StageAs. 2012-11-11 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121111 * autoconf.mk: avoid meta mode seeing changed commands for config.status * meta.autodep.mk: pass resolved MAKESYSPATH to gendirdeps in case we were found via .../mk * sys.clean-env.mk: move it from examples, we and others use it "as is". * FILES: add srctop.mk and options.mk * own.mk: convert to using options.mk which is modeled after FreeBSD's handling of MK_* but more flexible. This allows MK_* for boolean knobs to not be confused with MK* which can be commands. * examples/sys.clean-env.mk: add WITH[OUT]_ to MAKE_ENV_SAVE_PREFIX_LIST. Mention that HOME=/var/empty might be a good idea. 2012-11-08 Simon J. Gerraty * sys.dependfile.mk: if not depend file exists, $MACHINE specific ones are supported but not the default, check if any exist and follow suit. 2012-11-06 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121106 2012-11-05 Simon J. Gerraty * import latest dirdeps.mk and meta2deps.py from Juniper. * progs.mk: add MAN and CXXFLAGS to PROG_VARS also add PROGS_TARGETS and pass on PROG_CXX if it seems appropriate. 2012-11-04 Simon J. Gerraty * meta.stage.mk: update CLEANFILES remove redundant cp of .dirdep from STAGE_AS_SCRIPT. * progs.mk: Add LDADD to PROG_VARS 2012-10-12 Simon J. Gerraty * meta.stage.mk (STAGE_DIR_FILTER): track dirs we stage to in _STAGED_DIRS so that these can be turned into filters for GENDIRDEPS_FILTER. 2012-10-10 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20121010 * meta.stage.mk (STAGE_DIRDEP_SCRIPT): check that an existing target.dirdep matches .dirdep 2012-08-08 Simon J.

Gerraty * install-mk (MK_VERSION): bump version to 20120711 * dep.mk: add explicit dependencies on SRCS after applying SRCS_DEP_FILTER * meta.autodep.mk: add explicit dependencies on SRCS after applying SRCS_DEP_FILTER * meta.autodep.mk: ensure GENDIRDEPS_FILTER is exported if needed. 2012-06-26 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 20061106 add scripts.mk 2006-03-18 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20060318 * autodep.mk: avoid := when modifying OBJS into __dependsrcs 2006-03-02 Simon J. Gerraty * install-mk (MK_VERSION): bump version to 20060302 * autodep.mk: use -MF et al to help gcc+ccache DTRT. 2006-03-01 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 diff --git a/mk/FILES b/mk/FILES index efe9691ffe58..39ac101d36f4 100644 --- a/mk/FILES +++ b/mk/FILES @@ -1,83 +1,84 @@ ChangeLog FILES LICENSE README auto.obj.mk autoconf.mk autodep.mk auto.dep.mk cc-wrap.mk ccm.dep.mk compiler.mk cython.mk dep.mk doc.mk dpadd.mk files.mk final.mk host-target.mk host.libnames.mk inc.mk init.mk install-mk install-sh java.mk jobs.mk ldorder.mk lib.mk libnames.mk libs.mk links.mk man.mk manifest.mk mk-files.txt mkopt.sh newlog.sh nls.mk obj.mk options.mk own.mk posix.mk prlist.mk prog.mk progs.mk rst2htm.mk scripts.mk srctop.mk stage-install.sh subdir.mk suffixes.mk sys.mk sys.clean-env.mk sys.debug.mk sys.dependfile.mk sys.dirdeps.mk sys.vars.mk sys/AIX.mk +sys/Cygwin.mk sys/Darwin.mk sys/Generic.mk sys/HP-UX.mk sys/IRIX.mk sys/Linux.mk sys/NetBSD.mk sys/OSF1.mk sys/OpenBSD.mk sys/SCO_SV.mk sys/SunOS.mk sys/UnixWare.mk target-flags.mk warnings.mk whats.mk yacc.mk dirdeps.mk dirdeps-cache-update.mk dirdeps-options.mk dirdeps-targets.mk gendirdeps.mk install-new.mk meta2deps.py meta2deps.sh meta.sys.mk meta.autodep.mk meta.stage.mk meta.subdir.mk diff --git a/mk/init.mk b/mk/init.mk index 86dc577371cb..b6619721c943 100644 --- a/mk/init.mk +++ b/mk/init.mk @@ -1,121 +1,121 @@ # SPDX-License-Identifier: BSD-2-Clause # -# $Id: init.mk,v 1.37 2024/02/25 19:12:13 sjg Exp $ +# $Id: init.mk,v 1.38 2024/04/09 17:18:24 sjg Exp $ # # @(#) Copyright (c) 2002-2024, Simon J.
