2This is the README file for the "include" files for the FreeBSD
3source tree.  The files are installed in /usr/share/mk, and are by
4convention, named with the suffix ".mk".  These files store several
5build options and should be handled with caution.
6
7Note, this file is not intended to replace reading through the .mk
8files for anything tricky.
9
10There are two main types of make include files.  One type is the generally
11usable make include files, such as bsd.prog.mk and bsd.lib.mk.  The other is
12the internal make include files, such as bsd.files.mk and bsd.man.mk, which
13can not/should not be used directly but are used by the other make include
14files.  In most cases it is only interesting to include bsd.prog.mk or
15bsd.lib.mk.

58Random things worth knowing about this document:
59
60If appropriate when documenting the variables the default value is
61indicated using square brackets e.g. [gzip].
62In some cases the default value depend on other values (e.g. system
63architecture).  In these cases the most common value is indicated.
64
65This document contains some simple examples of the usage of the BSD make
66include files.  For more examples look at the makefiles in the FreeBSD
67source tree.

70
71RANDOM THINGS WORTH KNOWING:
72
73The files are like C-style #include files, and pretty much behave like
74you'd expect.  The syntax is slightly different in that a single '.' is
75used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
76
77One difference that will save you lots of debugging time is that inclusion
78of the file is normally done at the *end* of the Makefile.  The reason for
79this is because .mk files often modify variables and behavior based on the
80values of variables set in the Makefile.  To make this work, remember that
81the FIRST target found is the target that is used, i.e. if the Makefile has:
82
83	a:
84		echo a
85	a:
86		echo a number two
87
88the command "make a" will echo "a".  To make things confusing, the SECOND
89variable assignment is the overriding one, i.e. if the Makefile has:
90
91	a=	foo
92	a=	bar
93
94	b:
95		echo ${a}
96
97the command "make b" will echo "bar".  This is for compatibility with the
98way the V7 make behaved.
99
100It's fairly difficult to make the BSD .mk files work when you're building
101multiple programs in a single directory.  It's a lot easier to split up
102the programs than to deal with the problem.  Most of the agony comes from
103making the "obj" directory stuff work right, not because we switch to a new
104version of make.  So, don't get mad at us, figure out a better way to handle
105multiple architectures so we can quit using the symbolic link stuff.
106(Imake doesn't count.)
107
108The file .depend in the source directory is expected to contain dependencies
109for the source files.  This file is read automatically by make after reading
110the Makefile.
111
112The variable DESTDIR works as before.  It's not set anywhere but will change
113the tree where the file gets installed.
114
115The profiled libraries are no longer built in a different directory than
116the regular libraries.  A new suffix, ".po", is used to denote a profiled
117object, and ".pico" denotes a position-independent relocatable object.
118".nossppico" denotes a position-independent relocatable object without
119stack smashing protection and without sanitizer instrumentation.
120

153		A list of features that the compiler supports. Zero or
154		more of:
155			c++11	Supports full C++ 11 standard.

166
167The include file <sys.mk> has the default rules for all makes, in the BSD
168environment or otherwise.  You probably don't want to touch this file.
169
170=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
171
172The include file <bsd.arch.inc.mk> includes other Makefiles for specific
173architectures, if they exist. It will include the first of the following
174files that it finds: Makefile.${MACHINE}, Makefile.${MACHINE_ARCH},
175Makefile.${MACHINE_CPUARCH}
176
177=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
178
179The include file <bsd.man.mk> handles installing manual pages and their
180links.
181
182It has three targets:
183
184	all-man:
185		build manual pages.
186	maninstall:
187		install the manual pages and their links.
188	manlint:
189		verify the validity of manual pages.
190
191It sets/uses the following variables:
192
193MAN		The manual pages to be installed (use a .1 - .9 suffix).
194
195MANDIR		Base path for manual installation.
196
197MANGRP		Manual group.
198
199MANMODE		Manual mode.
200
201MANOWN		Manual owner.
202

204		or "/tahoe" for machine specific manual pages.
205
206MLINKS		List of manual page links (using a .1 - .9 suffix).  The
207		linked-to file must come first, the linked file second,
208		and there may be multiple pairs.  The files are hard-linked.
209
210The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
211it exists.
212
213=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
214
215The include file <bsd.own.mk> contains the owners, groups, etc. for both
216manual pages and binaries.
217
218It has no targets.
219
220It sets/uses the following variables:
221
222BINGRP		Binary group.
223
224BINMODE		Binary mode.
225
226BINOWN		Binary owner.
227

249
250SYMLINKGRP	Group of hard links created by INSTALL_[R]SYMLINK.
251
252SYMLINKMODE	Mode of hard links created by INSTALL_[R]SYMLINK.
253
254This file is generally useful when building your own Makefiles so that
255they use the same default owners etc. as the rest of the tree.
256
257=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
258
259The include file <bsd.prog.mk> handles building programs from one or
260more source files, along with their manual pages.  It has a limited number
261of suffixes, consistent with the current needs of the BSD tree.
262
263It has seven targets:
264
265	all:
266		build the program and its manual page
267	clean:
268		remove the program and any object files.
269	cleandir:
270		remove all of the files removed by the target clean, as
271		well as .depend, tags, and any manual pages.
272	depend:
273		make the dependencies for the source files, and store
274		them in the file .depend.
275	install:
276		install the program and its manual pages; if the Makefile
277		does not itself define the target install, the targets
278		beforeinstall and afterinstall may also be used to cause
279		actions immediately before and after the install target
280		is executed.
281	tags:
282		create a tags file for the source files.
283
284It sets/uses the following variables:
285
286ACFLAGS		Flags to the compiler when preprocessing and
287		assembling .S files.
288
289AFLAGS		Flags to the assembler when assembling .s files.
290
291BINGRP		Binary group.
292
293BINMODE		Binary mode.
294
295BINOWN		Binary owner.
296
297CFLAGS		Flags to the compiler when creating C objects.
298
299CLEANDIRS	Additional files (CLEANFILES) and directories (CLEANDIRS) to
300CLEANFILES	remove during clean and cleandir targets.  "rm -rf" and
301		"rm -f" are used, respectively.
302
303DIRS		A list of variables referring to directories.  For example:
304
305			DIRS+=	FOO
306			FOO=	/usr/share/foo
307
308		Owner, Group, Mode and Flags are handled by FOO_OWN,
309		FOO_GRP, FOO_MODE and FOO_FLAGS, respectively.
310
311		This allows FILESDIR to be set to FOO, and the directory
312		will be created before the files are installed and the
313		dependencies will be set correctly.
314
315DPADD		Additional dependencies for the program.  Usually used for
316		libraries.  For example, to depend on the compatibility and
317		utility libraries use:
318
319			DPADD=${LIBCOMPAT} ${LIBUTIL}
320
321		There is a predefined identifier for each (non-profiled,
322		non-shared) library and object.  Library file names are
323		transformed to identifiers by removing the extension and
324		converting to upper case.
325
326		There are no special identifiers for profiled or shared
327		libraries or objects.  The identifiers for the standard
328		libraries are used in DPADD.  This works correctly iff all
329		the libraries are built at the same time.  Unfortunately,
330		it causes unnecessary relinks to shared libraries when
331		only the static libraries have changed.  Dependencies on
332		shared libraries should be only on the library version
333		numbers.
334
335FILES		A list of non-executable files.
336		The installation is controlled by the FILESNAME, FILESOWN,
337		FILESGRP, FILESMODE, FILESDIR variables that can be
338		further specialized by FILES<VAR>_<file>.
339
340LDADD		Additional loader objects.  Usually used for libraries.
341		For example, to load with the compatibility and utility
342		libraries, use:
343
344			LDADD=-lutil -lcompat
345
346LDADD.${.TARGET:T}
347		Loader objects dependent on output file name.
348
349LDFLAGS		Additional loader flags. Passed to the loader via CC,
350		since that's used to link programs as well, so loader
351		specific flags need to be prefixed with -Wl, to work.
352
353LDFLAGS.${.TARGET:T}
354		Flags dependent on output file name.
355
356LIBADD		Additional libraries.  This is for base system libraries
357		and is only valid inside of the /usr/src tree.
358		Use LIBADD=name instead of LDADD=-lname.
359
360LIBADD.${.TARGET:T}
361		Libraries dependent on output file name.
362
363LINKS		The list of binary links; should be full pathnames, the
364		linked-to file coming first, followed by the linked
365		file.  The files are hard-linked.  For example, to link
366		/bin/test and /bin/[, use:
367
368			LINKS=	/bin/test /bin/[
369
370LINKOWN		Owner of links created with LINKS [${BINOWN}].
371
372LINKGRP		Group of links created with LINKS [${BINGRP}].
373
374LINKMODE	Mode of links created with LINKS [${BINMODE}].
375
376
377MAN		Manual pages.  If no MAN variable is defined,
378		"MAN=${PROG}.1" is assumed. See bsd.man.mk for more details.
379
380PROG		The name of the program to build.  If not supplied, nothing
381		is built.
382
383PROGNAME	The name that the above program will be installed as, if
384		different from ${PROG}.
385
386PROG_CXX	If defined, the name of the program to build.  Also
387		causes <bsd.prog.mk> to link the program with the
388		standard C++ library.  PROG_CXX overrides the value
389		of PROG if PROG is also set.
390
391PROGS		When used with <bsd.progs.mk>, allow building multiple
392PROGS_CXX	PROG and PROG_CXX in one Makefile.  To define
393		individual variables for each program the VAR.prog
394		syntax should be used.  For example:
395
396		PROGS=		foo bar
397		SRCS.foo=	foo_src.c
398		LDADD.foo=	-lutil
399		SRCS.bar=	bar_src.c
400
401		The supported variables are:
402		- BINDIR
403		- BINGRP
404		- BINMODE
405		- BINOWN
406		- CFLAGS
407		- CXXFLAGS
408		- DEBUG_FLAGS
409		- DPADD
410		- DPSRCS
411		- INTERNALPROG (no installation)
412		- LDADD
413		- LDFLAGS
414		- LIBADD
415		- LINKS
416		- MAN
417		- MLINKS
418		- MK_WERROR=no
419		- PROGNAME
420		- SRCS
421		- STRIP
422		- WARNS
423
424SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
425		The installation is controlled by the SCRIPTSNAME, SCRIPTSOWN,
426		SCRIPTSGRP, SCRIPTSMODE, SCRIPTSDIR variables that can be
427		further specialized by SCRIPTS<VAR>_<script>.
428
429SRCS		List of source files to build the program.  If SRCS is not
430		defined, it's assumed to be ${PROG}.c or, if PROG_CXX is
431		defined, ${PROG_CXX}.cc.
432
433STRIP		The flag passed to the install program to cause the binary
434		to be stripped.  This is to be used when building your
435		own install script so that the entire system can be made
436		stripped/not-stripped using a single nob.
437
438SUBDIR		A list of subdirectories that should be built as well.
439		Each of the targets will execute the same target in the
440		subdirectories.
441
442The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
443if it exists, as well as the include file <bsd.man.mk>.
444
445Some simple examples:
446
447To build foo from foo.c with a manual page foo.1, use:
448
449	PROG=	foo
450
451	.include <bsd.prog.mk>
452
453To build foo from foo.c with a manual page foo.2, add the line:
454
455	MAN=	foo.2
456
457If foo does not have a manual page at all, add the line:
458
459	MAN=
460
461If foo has multiple source files, add the line:
462
463	SRCS=	a.c b.c c.c d.c
464
465=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
466
467The include file, <bsd.compat.mk>, allows programs (built with
468<bsd.prog.mk>) to be built for one the ABI(s) supported by the
469top-level Makefile.libcompat.  It requires that <bsd.prog.mk> also be
470included.
471
472NEED_COMPAT	Build and link targeting a compatibility ABI or fail if it
473		is not available.  Supported values are "32", "soft", and
474		"any" being a wildcard.
475
476WANT_COMPAT	Similar to NEED_COMPAT, but build with the base ABI if
477		the specified ABI is not available.
478
479=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
480
481The include file, <bsd.snmpmod.mk>, handles building MIB modules for bsnmpd
482from one or more source files, along with their manual pages.  It has a
483limited number of suffixes, consistent with the current needs of the BSD
484tree.
485
486bsd.snmpmod.mk leverages bsd.lib.mk for building MIB modules and
487bsd.files.mk for installing MIB description and definition files.
488
489It implements the following additional targets:
490
491	smilint:
492		execute smilint on the MIBs defined by BMIBS.
493
494		The net-mgmt/libsmi package must be installed before
495		executing this target. The net-mgmt/net-snmp package
496		should be installed as well to reduce false positives
497		from smilint.
498
499It sets/uses the following variables:
500
501BMIBS		The MIB definitions to install.
502
503BMIBSDIR	The directory where the MIB definitions are installed.
504		This defaults to `${SHAREDIR}/snmp/mibs`.
505
506DEFS		The MIB description files to install.
507
508DEFSDIR		The directory where MIB description files are installed.
509		This defaults to `${SHAREDIR}/snmp/defs`.
510
511EXTRAMIBDEFS	Extra MIB description files to use as input when
512		generating ${MOD}_oid.h and ${MOD}_tree.[ch].
513
514EXTRAMIBSYMS	Extra MIB definition files used only for extracting
515		symbols.
516
517		EXTRAMIBSYMS are useful when resolving inter-module
518		dependencies and are useful with files containing only
519		enum-definitions.
520
521		See ${MOD}_oid.h for more details.
522
523LOCALBASE	The package root where smilint and the net-snmp
524		definitions can be found
525
526MOD		The bsnmpd module name.
527
528SMILINT		smilint binary to use with the smilint make target.
529
530SMILINT_FLAGS	flags to pass to smilint.
531
532SMIPATH		A colon-separated directory path where MIBs definitions
533		can be found. See "SMIPATH" in smi_config for more
534		details.
535
536XSYM		MIB names to extract symbols for. See ${MOD}_oid.h for
537		more details.
538
539It generates the following files:
540
541${MOD}_tree.c	A source file and header which programmatically describes
542${MOD}_tree.h	the MIB (type, OID name, ACCESS attributes, etc).
543
544		The files are generated via "gensnmptree -p".
545
546		See gensnmptree(1) for more details.
547
548${MOD}_oid.h	A header which programmatically describes the MIB root and
549		MIB tables.
550
551		The files are generated via "gensnmptree -e".
552
553		See gensnmptree(1) for more details.
554
555=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
556
557The include file <bsd.subdir.mk> contains the default targets for building
558subdirectories.  It has the same seven targets as <bsd.prog.mk>: all, clean,
559cleandir, depend, install, and tags.  For all of the directories listed in the
560variable SUBDIRS, the specified directory will be visited and the target made.
561There is also a default target which allows the command "make subdir" where
562subdir is any directory listed in the variable SUBDIRS.
563
564=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
565
566The include file <bsd.lib.mk> has support for building libraries.  It has the
567same seven targets as <bsd.prog.mk>: all, clean, cleandir, depend, install, and
568tags.  It has a limited number of suffixes, consistent with the current needs of
569the BSD tree.
570
571It sets/uses the following variables:
572
573LDADD		Additional loader objects.
574
575LIB		The name of the library to build.  Both a shared and static
576		library will be built.  NO_PIC can be set to only build a
577		static library.
578
579LIBADD		Additional libraries.  This is for base system libraries
580		and is only valid inside of the /usr/src tree.
581		Use LIBADD=name instead of LDADD=-lname.
582
583LIBDIR		Target directory for libraries.
584
585LIBGRP		Library group.
586
587LIBMODE		Library mode.
588
589LIBOWN		Library owner.
590
591LIBRARIES_ONLY	Do not build or install files other than the library.
592
593LIB_CXX		The name of the library to build. It also causes
594		<bsd.lib.mk> to link the library with the
595		standard C++ library.  LIB_CXX overrides the value
596		of LIB if LIB is also set.  Both a shared and static library
597		will be built.  NO_PIC can be set to only build a static
598		library.
599
600LINKS		The list of binary links; should be full pathnames, the
601		linked-to file coming first, followed by the linked
602		file.  The files are hard-linked.  For example, to link
603		/bin/test and /bin/[, use:
604
605			LINKS=	/bin/test /bin/[
606
607LINKOWN		Owner of links created with LINKS [${LIBOWN}].
608
609LINKGRP		Group of links created with LINKS [${LIBGRP}].
610
611LINKMODE	Mode of links created with LINKS [${LIBMODE}].
612
613MAN		The manual pages to be installed. See bsd.man.mk for more
614		details.
615
616SHLIB		Like LIB but only builds a shared library.
617
618SHLIB_CXX	Like LIB_CXX but only builds a shared library.
619
620SHLIB_LDSCRIPT	Template file to generate shared library linker script.
621		If not defined, a simple symlink is created to the real
622		shared object.
623
624SRCS		List of source files to build the library.  Suffix types
625		.s, .c, and .f are supported.  Note, .s files are preferred
626		to .c files of the same name.  (This is not the default for
627		versions of make.)
628
629The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
630if it exists, as well as the include file <bsd.man.mk>.
631
632It has rules for building profiled objects; profiled libraries are
633built by default.
634
635Libraries are ranlib'd before installation.
636
637=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
638
639The include file <bsd.test.mk> handles building one or more test programs
640intended to be used in the FreeBSD Test Suite under /usr/tests/.
641
642It has seven targets:
643
644	all:
645		build the test programs.
646	check:
647		runs the test programs with kyua test.
648
649		The beforecheck and aftercheck targets will be invoked, if
650		defined, to execute commands before and after the realcheck
651		target has been executed, respectively.
652
653		The devel/kyua package must be installed before invoking this
654		target.
655	clean:
656		remove the test programs and any object files.
657	cleandir:
658		remove all of the files removed by the target clean, as
659		well as .depend and tags.
660	depend:
661		make the dependencies for the source files, and store
662		them in the file .depend.
663	install:
664                install the test programs and their data files; if the
665                Makefile does not itself define the target install, the
666                targets beforeinstall and afterinstall may also be used
667                to cause actions immediately before and after the
668                install target is executed.
669	tags:
670		create a tags file for the source files.
671
672It sets/uses the following variables, among many others:
673
674ATF_TESTS_C	The names of the ATF C test programs to build.
675
676ATF_TESTS_CXX	The names of the ATF C++ test programs to build.
677
678ATF_TESTS_SH	The names of the ATF sh test programs to build.
679
680GTESTS		The names of the GoogleTest test programs to build.
681
682KYUAFILE	If 'auto' (the default), generate a Kyuafile out of the
683		test programs defined in the Makefile.  If 'yes', then a
684		manually-crafted Kyuafile must be supplied with the
685		sources.  If 'no', no Kyuafile is installed (useful for
686		subdirectories providing helper programs or data files
687		only).
688
689LOCALBASE	The --prefix for the kyua package.
690
691		The value of LOCALBASE defaults to /usr/local .
692
693NOT_FOR_TEST_SUITE
694		If defined, none of the built test programs get
695		installed under /usr/tests/ and no Kyuafile is
696		automatically generated.  Should not be used within the
697		FreeBSD source tree but is provided for the benefit of
698		third-parties.
699
700PLAIN_TESTS_C	The names of the plain (legacy) programs to build.
701
702PLAIN_TESTS_CXX	The names of the plain (legacy) test programs to build.
703
704PLAIN_TESTS_SH	The names of the plain (legacy) test programs to build.
705
706TAP_PERL_INTERPRETER
707		Path to the Perl interpreter to be used for
708		TAP-compliant test programs that are written in Perl.
709		Refer to TAP_TESTS_PERL for details.
710
711TAP_TESTS_C	The names of the TAP-compliant C test programs to build.
712
713TAP_TESTS_CXX	The names of the TAP-compliant C++ test programs to
714		build.
715
716TAP_TESTS_PERL	The names of the TAP-compliant Perl test programs to
717		build.  The corresponding source files should end with
718		the .pl extension; the test program is marked as
719		requiring Perl; and TAP_PERL_INTERPRETER is used in the
720		built scripts as the interpreter of choice.
721
722TAP_TESTS_SH	The names of the TAP-compliant sh test programs to
723		build.
724
725TESTSBASE	Installation prefix for tests. Defaults to /usr/tests
726
727TESTSDIR	Path to the installed tests.  Must be a subdirectory of
728		TESTSBASE and the subpath should match the relative
729		location of the tests within the src tree.
730
731		The value of TESTSDIR defaults to
732		${TESTSBASE}/${RELDIR:H} , e.g. /usr/tests/bin/ls when
733		included from bin/ls/tests .
734
735TESTS_SUBDIRS	List of subdirectories containing tests into which to
736		recurse.  Differs from SUBDIR in that these directories
737		get registered into the automatically-generated
738		Kyuafile (if any).
739
740The actual building of the test programs is performed by <bsd.prog.mk>.
741Please see the documentation above for this other file for additional
742details on the behavior of <bsd.test.mk>.
