4This is the README file for the make "include" files for the NetBSD
5source tree.  The files are installed in /usr/share/mk, and are,
6by convention, named with the suffix ".mk".
7
8Note, this file is not intended to replace reading through the .mk
9files for anything tricky.

13RANDOM THINGS WORTH KNOWING:
14
15The files are simply C-style #include files, and pretty much behave like
16you'd expect.  The syntax is slightly different in that a single '.' is
17used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
18
19One difference that will save you lots of debugging time is that inclusion
20of the file is normally done at the *end* of the Makefile.  The reason for
21this is because .mk files often modify variables and behavior based on the
22values of variables set in the Makefile.  To make this work, remember that
23the FIRST target found is the target that is used, i.e. if the Makefile has:
24
25	a:
26		echo a
27	a:
28		echo a number two
29
30the command "make a" will echo "a".  To make things confusing, the SECOND
31variable assignment is the overriding one, i.e. if the Makefile has:
32
33	a=	foo
34	a=	bar
35
36	b:
37		echo ${a}
38
39the command "make b" will echo "bar".  This is for compatibility with the
40way the V7 make behaved.
41
42It's fairly difficult to make the BSD .mk files work when you're building
43multiple programs in a single directory.  It's a lot easier to split up the
44programs than to deal with the problem.  Most of the agony comes from making
45the "obj" directory stuff work right, not because we switched to a new version
46of make.  So, don't get mad at us, figure out a better way to handle multiple
47architectures so we can quit using the symbolic link stuff.  (Imake doesn't
48count.)
49
50The file .depend in the source directory is expected to contain dependencies
51for the source files.  This file is read automatically by make after reading
52the Makefile.
53
54The variable DESTDIR works as before.  It's not set anywhere but will change
55the tree where the file gets installed.
56
57The profiled libraries are no longer built in a different directory than
58the regular libraries.  A new suffix, ".po", is used to denote a profiled
59object, and ".pico" denotes a shared (position-independent) object.
60
61There are various make variables used during the build.
62
63Many variables support a (case sensitive) value of "no" or "yes",
64and are tested with  ${VAR} == "no"  and  ${VAR} != "no" .
65
66
67The basic rule for the variable naming scheme is as follows:
68
69HOST_xxx	A command that runs on the host machine regardless of
70		whether or not the system is being cross compiled, or
71		flags for such a command.
72
73MKxxx		Can be set to "no" to disable functionality, or
74		"yes" to enable it.
75		Usually defaults to "yes", although some variables
76		default to "no".
77		Due to make(1) implementation issues, if a temporary
78		command-line override of a mk.conf(5) or <bsd.own.mk>
79		setting is required whilst still honoring a particular
80		Makefile's setting of MKxxx, use
81			env MKxxx=value make
82		instead of
83			make MKxxx=value
84
85NOxxx		If defined, disables a feature.
86		Not intended for users.
87		This is to allow Makefiles to disable functionality
88		that they don't support (such as missing man pages).
89		NOxxx variables must be defined before <bsd.own.mk>
90		is included.
91
92TOOL_xxx	A tool that is provided as part of the USETOOLS
93		framework.  When not using the USETOOLS framework,
94		TOOL_xxx variables should refer to tools that are
95		already installed on the host system.
96
97The following variables that control how things are made/installed that
98are not set by default. These should not be set by Makefiles; they're for
99the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5))
100or on the make(1) command line:
101
102BUILD 		If defined, 'make install' checks that the targets in the
103		source directories are up-to-date and remakes them if they
104                are out of date, instead of blindly trying to install
105                out of date or non-existent targets.
106
107MAKEVERBOSE	Control how "verbose" the standard make(1) rules are.
108		Default: 2
109		Supported values:
110		    0	Minimal output ("quiet")
111		    1	Describe what is occurring
112		    2	Describe what is occurring and echo the actual command
113		    3	Ignore the effect of the "@" prefix in make commands
114		    4	Trace shell commands using the shell's -x flag
115
116MKATF		If "no", don't build the Automated Testing Framework (ATF),
117		which includes the libatf-c, libatf-c++ and libatf-sh libraries
118		and the various command line tools.  Also, because the build of
119		the libraries is disabled, don't build the NetBSD test suite
120		either.
121		Default: yes
122
123MKBFD		Obsolete, use MKBINUTILS

206		Default: yes
207

409MKSTRIPSYM	If "yes", strip all local symbols from shared libraries;
410		the affect is equivalent to -x option of ld(1). If "no",
411		strip only temporary local symbols; the affect is equivalent
412		to -X option of ld(1). Keeping non-temporary local symbols
413		such as static function names is useful on using DTrace for
414		userland libraries and getting a backtrace from a rump kernel

432		Default: no
433
434MKUPDATE 	If not "no", 'make install' only installs targets that are
435		more recently modified in the source directories that their
436		installed counterparts.
437		Default: no
438
439MKX11		If not "no", 'make build' also descends into 
440		src/external/mit/xorg to cross-build X11 and automatically
441		enables creation of X sets.
442		Default: no
443
444MKX11FONTS	If not "no", do not build or install the X fonts.  The xfont
445		set is still created but will be empty.
446		Default: yes
447
448MKX11MOTIF:	If "yes", build the native X11 libGLw with Motif stubs.  If
449		Motif is not installed in the default location /usr/pkg, the
450		location can be specified using the X11MOTIFPATH variable.

452
453MKYP		If "no", disables building of YP (NIS)
454		infrastructure (libraries and support programs).
455		Default: yes
456
457MKZFS		If "no", do not build and install utilities and libraries

462
463MKRUMP		If "no", do not build and install rump related headers,
464		libraries, and programs.

466
467USE_HESIOD	If "no", disables building Hesiod support into
468		various system utilities/libraries that support it.
469		If ${MKHESIOD} is "no", USE_HESIOD will also be
470		forced to "no".
471
472USE_INET6	If "no", disables building INET6 (IPv6) support into
473		various system utilities/libraries that support it.
474		If ${MKINET6} is "no", USE_INET6 will also be
475		forced to "no".
476
477USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
478		designed for improved performance with threaded
479		applications.  The "phkmalloc" allocator as used up
480		before NetBSD-5.0 will be substituted.
481
482USE_KERBEROS	If "no", disables building Kerberos v5
483		support into various system utilities/libraries that
484		support it.  If ${MKKERBEROS} is "no", USE_KERBEROS

494
495USE_SKEY	If "no", disables building S/key authentication
496		support into various system utilities/libraries that
497		support it.  If ${MKSKEY} is "no", USE_SKEY will
498		also be forced to "no".
499		Default: no
500
501USE_SSP		If "no", disables GCC stack protection code, which
502		detects stack overflows and aborts the program. The
503		stack protection code imposes a performance penalty
504		of about 5%.
505		Default: "no", unless "USE_FORT" is set to "yes"
506
507NOSSP		Don't compile with stack protector during build.
508		It is set internally for standalone programs.
509
510USE_FORT 	If "yes" turns on substitute wrappers for commonly used
511		functions that do not do bounds checking regularly, but
512		they could in some cases by using the gcc
513		__builtin_object_size() function to determine the buffer
514		size where it is known and detect buffer overflows.
515		These substitute functions are in /usr/include/ssp.
516		Default: depends on the part of the source tree
517
518NOFORT		Don't compile with substitute wrappers during build.
519		It is set internally for standalone programs.

541		or program.  <lib> corresponds to the LIB variable set in
542		the library's makefile.  <prog> corresponds to either PROG
543		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
544		set to "-g", "-g" will be added to COPTS only when compiling
545		the crypto library.
546
547The active compiler is selected using the following variables:
548AVAILABLE_COMPILER
549		List of available compiler suites.  Processed in order
550		for selecting the active compiler for each frontend.
551HAVE_PCC	If defined, PCC is present and enabled.
552HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
553UNSUPPORTED_COMPILER.xxx
554		If defined, the support for compiler "xxx" is disabled.
555
556For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
557ACTIVE_CC	Active compile suite for the CC frontend.
558SUPPORTED_CC	Compile suite with support for the CC frontend.
559TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
560
561=-=-=-=-=   sys.mk   =-=-=-=-=
562
563The include file <sys.mk> has the default rules for all makes, in the BSD
564environment or otherwise.  You probably don't want to touch this file.
565
566=-=-=-=-=   bsd.own.mk   =-=-=-=-=
567
568The include file <bsd.own.mk> contains source tree configuration parameters,
569such as the owners, groups, etc. for both manual pages and binaries, and
570a few global "feature configuration" parameters.
571
572It has no targets.
573
574To get system-specific configuration parameters, <bsd.own.mk> will try to
575include the file specified by the "MAKECONF" variable.  If MAKECONF is not
576set, or no such file exists, the system make configuration file, /etc/mk.conf
577is included.  These files may define any of the variables described below.
578
579<bsd.own.mk> sets the following variables, if they are not already defined
580(defaults are in brackets):
581
582NETBSDSRCDIR	Top of the NetBSD source tree.
583		If _SRC_TOP_ != "", that will be used as the default,
584		otherwise BSDSRCDIR will be used as the default.
585		Various makefiles within the NetBSD source tree will
586		use this to reference the top level of the source tree.
587
588_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
589		based on the presence of tools/ and build.sh.  This variable
590		is "internal" to <bsd.own.mk>, although its value is only
591		determined once and then propagated to all sub-makes.
592
593_NETBSD_VERSION_DEPENDS
594		A list of files which contain information about
595		the version of the NetBSD being built.  This is
596		defined only if the current directory appears
597		to be inside a NetBSD source tree.  The list of
598		files includes ${NETBSDSRCDIR}/sys/sys/param.h
599		(which contains the kernel version number),
600		${NETBSDSRCDIR}/sys/conf/newvers.sh and
601		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
602		interpret the information in sys/sys/param.h), and
603		${_SRC_TOP_OBJ_}/params (which is an optional file,
604		created by "make build" in ${_SRC_TOP_}/Makefile,
605		containing all the variables that may influence the
606		build).
607
608		Targets that depend on the NetBSD version, or on
609		variables defined at build time, can declare a
610		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
611
612			version.c: ${_NETBSD_VERSION_DEPENDS}
613				commands to create version.c
614
615BSDSRCDIR	The real path to the system sources, so that 'make obj'
616		will work correctly.  [/usr/src]

699
700X11USRLIBDIR	X11 library directory.  [${X11ROOTDIR}/lib]
701
702STRIPFLAG	The flag passed to the install program to cause the binary
703		to be stripped.  This is to be used when building your
704		own install script so that the entire system can be made
705		stripped/not-stripped using a single knob.  []
706
707COPY		The flag passed to the install program to cause the binary
708		to be copied rather than moved.  This is to be used when
709		building our own install script so that the entire system
710		can either be installed with copies, or with moves using
711		a single knob.  [-c]
712
713MAKEDIRTARGETENV
714		Environment variables passed to the child make process
715		invoked by MAKEDIRTARGET.
716
717MAKEDIRTARGET dir target [params]
718		Runs "cd $${dir} && ${MAKE} [params] $${target}",
719		displaying a "pretty" message whilst doing so.
720
721RELEASEMACHINEDIR
722		Subdirectory used below RELEASEDIR when building
723		a release.  [${MACHINE}]
724
725RELEASEMACHINE	Subdirectory or path component used for the following
726		paths:
727			distrib/${RELEASEMACHINE}
728			distrib/notes/${RELEASEMACHINE}
729			etc/etc.${RELEASEMACHINE}
730		Used when building a release.  [${MACHINE}]
731
732Additionally, the following variables may be set by <bsd.own.mk> or in a
733make configuration file to modify the behavior of the system build
734process (default values are in brackets along with comments, if set by
735<bsd.own.mk>):
736
737USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
738		be used as part of a build in progress.
739		Supported values:
740
741		yes	Use the tools from TOOLDIR.
742			Must be set to this if cross-compiling.
743
744		no	Do not use the tools from TOOLDIR, but refuse to
745			build native compilation tool components that are
746			version-specific for that tool.
747
748		never	Do not use the tools from TOOLDIR, even when
749			building native tool components.  This is similar to
750			the traditional NetBSD build method, but does not
751			verify that the compilation tools in use are
752			up-to-date enough in order to build the tree
753			successfully.  This may cause build or runtime
754			problems when building the whole NetBSD source tree.
755
756		Default: "yes" if building all or part of a whole NetBSD
757		source tree (detected automatically); "no" otherwise
758		(to preserve traditional semantics of the <bsd.*.mk>
759		make(1) include files).
760
761OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
762		use ELF -- currently all architectures].
763
764TOOLCHAIN_MISSING
765		If not "no", this indicates that the platform being built
766		does not have a working in-tree toolchain.  If the
767		${MACHINE_ARCH} in question falls into this category,
768		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
769		Otherwise, the variable is unconditionally assigned the
770		value "no".
771		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
772		unconditionally assigned the value "no".
773
774EXTERNAL_TOOLCHAIN
775		This variable is not directly set by <bsd.own.mk>, but
776		including <bsd.own.mk> is the canonical way to gain
777		access to this variable.  The variable should be defined
778		either in the user's environment or in the user's mk.conf
779		file.  If defined, this variable indicates the root of
780		an external toolchain which will be used to build the
781		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
782		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
783		cross-compile framework.
784
785		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
786		assigned the value "no", since the external version of the
787		compiler may not be able to build the library components of
788		the in-tree compiler.
789
790		NOTE: This variable is not yet used in as many places as
791		it should be.  Expect the exact semantics of this variable
792		to change in the short term as parts of the cross-compile
793		framework continue to be cleaned up.
794
795The following variables are defined to commands to perform the
796appropriate operation, with the default in [brackets].  Note that
797the defaults change if USETOOLS == "yes":
798
799TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

949
950<bsd.own.mk> is generally useful when building your own Makefiles so that
951they use the same default owners etc. as the rest of the tree.
952
953
954=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
955
956The include file <bsd.clean.mk> defines the clean and cleandir
957targets.  It uses the following variables:
958
959CLEANFILES	Files to remove for both the clean and cleandir targets.
960
961CLEANDIRFILES	Files to remove for the cleandir target, but not for
962		the clean target.
963
964MKCLEANSRC	Controls whether or not the clean and cleandir targets
965		will delete files from both the object directory,
966		${.OBJDIR}, and the source directory, ${.CURDIR}.
967
968		If MKCLEANSRC is set to "no", then the file names in
969		CLEANFILES or CLEANDIRFILES are interpreted relative
970		to the object directory, ${.OBJDIR}.  This is the
971		traditional behaviour.
972
973		If MKCLEANSRC is set to "yes", then the file deletion
974		is performed relative to both the object directory,
975		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
976		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
977		Deleting files from ${.CURDIR} is intended to remove
978		stray output files that had been left in the source
979		directory by an earlier build that did not use object
980		directories.
981
982		The default is MKCLEANSRC=yes.  If you always build with
983		separate object directories, and you are sure that there
984		are no stray files in the source directories, then you
985		may set MKCLEANSRC=no to save some time.
986
987MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
988		will verify that files have been deleted.
989
990		If MKCLEANVERIFY is set to "no", then the files will
991		be deleted using a "rm -f" command, and its success or
992		failure will be ignored.
993
994		If MKCLEANVERIFY is set to "yes", then the success of
995		the "rm -f" command will be verified using an "ls"
996		command.
997
998		The default is MKCLEANVERIFY=yes.  If you are sure that
999		there will be no problems caused by file permissions,
1000		read-only file systems, or the like, then you may set
1001		MKCLEANVERIFY=no to save some time.
1002
1003To use the clean and cleandir targets defined in <bsd.clean.mk>, other
1004Makefiles or bsd.*.mk files should append file names to the CLEANFILES
1005or CLEANDIRFILES variables.  For example:
1006
1007	    CLEANFILES+= a.out
1008	    CLEANDIRFILES+= .depend
1009
1010	    .include <bsd.clean.mk>
1011
1012The files listed in CLEANFILES and CLEANDIRFILES must not be
1013directories, because the potential risk from running "rm -rf" commands
1014in bsd.clean.mk is considered too great.  If you want to recursively
1015delete a directory as part of "make clean" or "make cleandir" then you
1016need to provide your own target.
1017
1018=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
1019
1020The include file <bsd.dep.mk> contains the default targets for building
1021.depend files.  It creates .d files from entries in SRCS and DPSRCS
1022that are C, C++, or Objective C source files, and builds .depend from the
1023.d files.  All other files in SRCS and all of DPSRCS will be used as
1024dependencies for the .d files.  In order for this to function correctly,
1025it should be .included after all other .mk files and directives that may
1026modify SRCS or DPSRCS.  It uses the following variables:
1027
1028SRCS		List of source files to build the program.
1029
1030DPSRCS		List of source files which are needed for generating
1031		dependencies, but are not needed in ${SRCS}.
1032
1033
1034=-=-=-=-=   bsd.files.mk   =-=-=-=-=
1035
1036The include file <bsd.files.mk> handles the FILES variables and is included
1037from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1038
1039FILES		The list of files to install.
1040
1041CONFIGFILES	Similar semantics to FILES, except that the files
1042		are installed by the `configinstall' target,
1043		not the `install' target.
1044		The FILES* variables documented below also apply.
1045
1046FILESOWN	File owner.  [${BINOWN}]
1047
1048FILESGRP	File group.  [${BINGRP}]
1049
1050FILESMODE	File mode.  [${NONBINMODE}]
1051
1052FILESDIR	The location to install the files.
1053
1054FILESNAME	Optional name to install each file as.
1055
1056FILESOWN_<fn>	File owner of the specific file <fn>.
1057
1058FILESGRP_<fn>	File group of the specific file <fn>.
1059
1060FILESMODE_<fn>	File mode of the specific file <fn>.
1061
1062FILESDIR_<fn>	The location to install the specific file <fn>.
1063
1064FILESNAME_<fn>	Optional name to install <fn> as.
1065
1066FILESBUILD	If this variable is defined, then its value will be
1067		used as the default for all FILESBUILD_<fn> variables.
1068		Otherwise, the default will be "no".
1069
1070FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1071		targets to be built by `realall'.  Users of that variable
1072		should provide a target to build the file.
1073
1074
1075BUILDSYMLINKS	List of two word items:
1076			lnsrc lntgt
1077		For each lnsrc item, create a symlink named lntgt.
1078		The lntgt symlinks are removed by the cleandir target.
1079
1080UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1081		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1082		The source files have a `.uue' suffix, the generated files do
1083		not.
1084
1085UUDECODE_FILES_RENAME_<fn>
1086		Rename the output from the decode to the provided name.
1087		
1088		*NOTE: These files are simply decoded, with no install or other
1089		       rule applying implicitly except being added to the clean
1090		       target.
1091
1092=-=-=-=-=   bsd.gcc.mk   =-=-=-=-=
1093
1094The include file <bsd.gcc.mk> computes various parameters related to GCC
1095support libraries.  It defines no targets.  <bsd.own.mk> MUST be included
1096before <bsd.gcc.mk>.
1097
1098The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
1099of which need to know where to find certain GCC support libraries.
1100
1101The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
1102which is generally set by the user.  If EXTERNAL_TOOLCHAIN it set, then
1103the compiler is asked where to find the support libraries, otherwise the
1104support libraries are found in ${DESTDIR}/usr/lib.
1105
1106<bsd.gcc.mk> sets the following variables:
1107
1108_GCC_CRTBEGIN	The full path name to crtbegin.o.
1109
1110_GCC_CRTBEGINS	The full path name to crtbeginS.o.
1111
1112_GCC_CRTEND	The full path name to crtend.o.
1113
1114_GCC_CRTENDS	The full path name to crtendS.o.
1115
1116_GCC_LIBGCCDIR	The directory where libgcc.a is located.
1117
1118
1119=-=-=-=-=   bsd.inc.mk   =-=-=-=-=
1120
1121The include file <bsd.inc.mk> defines the includes target and uses the
1122variables:
1123
1124INCS		The list of include files.
1125
1126INCSDIR		The location to install the include files.
1127
1128INCSNAME	Target name of the include file, if only one; same as
1129		FILESNAME, but for include files.
1130
1131INCSYMLINKS	Similar to SYMLINKS in <bsd.links.mk>, except that these
1132		are installed in the 'includes' target and not the
1133		(much later) 'install' target.
1134
1135INCSNAME_<file>	The name file <file> should be installed as, if not <file>,
1136		same as FILESNAME_<file>, but for include files.
1137
1138
1139=-=-=-=-=   bsd.info.mk   =-=-=-=-=
1140
1141The include file <bsd.info.mk> is used to generate and install GNU Info
1142documentation from respective Texinfo source files.  It defines three
1143implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
1144following variables:
1145
1146TEXINFO		List of Texinfo source files.  Info documentation will
1147		consist of single files with the extension replaced by
1148		.info.
1149
1150INFOFLAGS	Flags to pass to makeinfo.  []
1151
1152
1153=-=-=-=-=   bsd.kernobj.mk   =-=-=-=-=
1154
1155The include file <bsd.kernobj.mk> defines variables related to the
1156location of kernel sources and object directories.
1157
1158KERNSRCDIR	Is the location of the top of the kernel src.
1159		[${_SRC_TOP_}/sys]
1160
1161KERNARCHDIR	Is the location of the machine dependent kernel sources.
1162		[arch/${MACHINE}]
1163
1164KERNCONFDIR	Is where the configuration files for kernels are found.
1165		[${KERNSRCDIR}/${KERNARCHDIR}/conf]
1166
1167KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
1168		instance will be compiled in ${KERNOBJDIR}/GENERIC.
1169		The default value is
1170		${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
1171		if it exists or the target 'obj' is being made.
1172		Otherwise the default is
1173		${KERNSRCDIR}/${KERNARCHDIR}/compile.
1174
1175It is important that Makefiles (such as those under src/distrib) that
1176wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
1177rather than make assumptions about the location of the compiled kernel.
1178
1179
1180=-=-=-=-=   bsd.kinc.mk   =-=-=-=-=
1181
1182The include file <bsd.kinc.mk> defines the many targets (includes,
1183subdirectories, etc.), and is used by kernel makefiles to handle
1184include file installation.  It is intended to be included alone, by
1185kernel Makefiles.  It uses similar variables to <bsd.inc.mk>.
1186Please see <bsd.kinc.mk> for more details, and keep the documentation
1187in that file up to date.
1188
1189=-=-=-=-=   bsd.syscall.mk =-=-=-=-=
1190
1191The include file <bsd.syscall.mk> contains the logic to create syscall
1192files for various emulations. It includes <bsd.kinc.mk> to handle the
1193rest of the targets.
1194
1195=-=-=-=-=   bsd.lib.mk   =-=-=-=-=
1196
1197The include file <bsd.lib.mk> has support for building libraries.  It has
1198the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1199includes, install, lint, and tags.  Additionally, it has a checkver target
1200which checks for installed shared object libraries whose version is greater
1201that the version of the source. It has a limited number of suffixes,
1202consistent with the current needs of the BSD tree.  <bsd.lib.mk> includes
1203<bsd.shlib.mk> to get shared library parameters.
1204
1205It sets/uses the following variables:
1206
1207LIB		The name of the library to build.
1208
1209LIBDIR		Target directory for libraries.
1210
1211MKARZERO	Normally, ar(1) sets the timestamps, uid, gid and
1212		permissions in files inside its archives to those of
1213		the file it was fed. This leads to non-reproducible
1214		builds. If MKARZERO is set to "yes" (default is the
1215		same as MKREPRO, or "no" if MKREPRO is not defined),
1216		then the "D" flag is passed to ar, causing the
1217		timestamp, uid and gid to be zeroed and the file
1218		permissions to be set to 644. This allows .a files
1219		from different builds to be bit identical.
1220
1221SHLIBINSTALLDIR	Target directory for shared libraries if ${USE_SHLIBDIR}
1222		is not "no".
1223
1224SHLIB_MAJOR
1225SHLIB_MINOR
1226SHLIB_TEENY	Major, minor, and teeny version numbers of shared library
1227
1228USE_SHLIBDIR	If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
1229		as the path to install shared libraries to.
1230		USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
1231		Default: no
1232
1233LIBISMODULE	If not "no", install as ${LIB}.so (without the "lib" prefix),
1234		and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
1235		MKPROFILE=no MKSTATICLIB=no".
1236		Default: no
1237
1238LIBISPRIVATE	If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
1239		MKPROFILE=no", and don't install the (.a) library.
1240		This is useful for "build only" helper libraries.
1241		Default: no
1242
1243LIBISCXX	If not "no", Use ${CXX} instead of ${CC} to link
1244		shared libraries.
1245		This is useful for C++ libraries.
1246		Default: no
1247
1248LINTLIBDIR	Target directory for lint libraries.
1249
1250LIBGRP		Library group.
1251
1252LIBOWN		Library owner.
1253
1254LIBMODE		Library mode.
1255
1256LDADD		Additional loader objects.
1257
1258MAN		The manual pages to be installed (use a .1 - .9 suffix).
1259
1260NOCHECKVER_<library>
1261NOCHECKVER	If set, disables checking for installed shared object
1262		libraries with versions greater than the source.  A
1263		particular library name, without the "lib" prefix, may
1264		be appended to the variable name to disable the check for
1265		only that library.
1266
1267SRCS		List of source files to build the library.  Suffix types
1268		.s, .c, and .f are supported.  Note, .s files are preferred
1269		to .c files of the same name.  (This is not the default for
1270		versions of make.)
1271
1272LIBDPLIBS	A list of the tuples:
1273			libname  path-to-srcdir-of-libname
1274
1275		For each tuple;
1276		     *	LIBDO.libname contains the .OBJDIR of the library
1277			`libname', and if it is not set it is determined
1278			from the srcdir and added to MAKEOVERRIDES (the
1279			latter is to allow for build time optimization).
1280		     *	LDADD gets  -L${LIBDO.libname} -llibname    added.
1281		     *	DPADD gets  ${LIBDO.libname}/liblibname.so  or
1282				    ${LIBDO.libname}/liblibname.a   added.
1283
1284		The special value "_external" for LIBDO.lib makes the
1285		build system to assume the library comes from outside
1286		of the NetBSD source tree and only causes -llibname
1287		to be added to LDADD.
1288
1289		This variable may be used for individual libraries, as
1290		well as in parent directories to cache common libraries
1291		as a build-time optimization.
1292
1293The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1294if it exists, as well as the include file <bsd.man.mk>.
1295
1296It has rules for building profiled objects; profiled libraries are
1297built by default.
1298
1299Libraries are ranlib'd when made.
1300
1301
1302=-=-=-=-=   bsd.links.mk   =-=-=-=-=
1303
1304The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1305and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1306
1307LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1308is used. The defaults may be modified by other bsd.*.mk files which
1309include bsd.links.mk.  In the future, these variables may be replaced
1310by a method for explicitly recording hard links in a metadata log.
1311
1312LINKS		The list of hard links, consisting of pairs of paths:
1313			source-file target-file
1314		${DESTDIR} is prepended to both paths before linking.
1315		For example, to link /bin/test and /bin/[, use:
1316			LINKS=/bin/test /bin/[
1317
1318CONFIGLINKS	Similar semantics to LINKS, except that the links
1319		are installed by the `configinstall' target,
1320		not the `install' target.
1321
1322SYMLINKS	The list of symbolic links, consisting of pairs of paths:
1323			source-file target-file
1324		${DESTDIR} is only prepended to target-file before linking.
1325		For example, to symlink /usr/bin/tar to /bin/tar resulting
1326		in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1327			SYMLINKS=/bin/tar /usr/bin/tar
1328
1329CONFIGSYMLINKS	Similar semantics to SYMLINKS, except that the symbolic links
1330		are installed by the `configinstall' target,
1331		not the `install' target.
1332
1333LINKSOWN	Link owner.  [${BINOWN}]
1334
1335LINKSGRP	Link group.  [${BINGRP}]
1336
1337LINKSMODE	Link mode.  [${NONBINMODE}]
1338
1339LINKSOWN_<fn>	Link owner of the specific file <fn>.
1340
1341LINKSGRP_<fn>	Link group of the specific file <fn>.
1342
1343LINKSMODE_<fn>	Link mode of the specific file <fn>.
1344
1345
1346=-=-=-=-=   bsd.man.mk   =-=-=-=-=
1347
1348The include file <bsd.man.mk> handles installing manual pages and their
1349links.
1350
1351It has a three targets:
1352
1353	catinstall:
1354		Install the preformatted manual pages and their links.
1355	htmlinstall:
1356		Install the HTML manual pages and their links.
1357	maninstall:
1358		Install the manual page sources and their links.
1359
1360It sets/uses the following variables:
1361
1362MANDIR		Base path for manual installation.
1363
1364MANGRP		Manual group.
1365
1366MANOWN		Manual owner.
1367
1368MANMODE		Manual mode.
1369
1370MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
1371		or "/tahoe" for machine specific manual pages.
1372
1373MAN		The manual pages to be installed (use a .1 - .9 suffix).
1374
1375MLINKS		List of manual page links (using a .1 - .9 suffix).  The
1376		linked-to file must come first, the linked file second,
1377		and there may be multiple pairs.
1378
1379The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1380it exists.
1381
1382
1383=-=-=-=-=   bsd.obj.mk   =-=-=-=-=
1384
1385The include file <bsd.obj.mk> defines targets related to the creation
1386and use of separated object and source directories.
1387
1388If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1389${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1390it exists.  Otherwise make(1) looks for the existence of a
1391subdirectory (or a symlink to a directory) of the source directory
1392into which built targets should be placed.  If an environment variable
1393named MAKEOBJDIR is set, make(1) uses its value as the name of the
1394object directory; failing that, make first looks for a subdirectory
1395named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1396
1397Object directories are not created automatically by make(1) if they
1398don't exist; you need to run a separate "make obj".  (This will happen
1399during a top-level build if "MKOBJDIRS" is set to a value other than
1400"no").  When the source directory is a subdirectory of ${BSDSRCDIR} --
1401and this is determined by a simple string prefix comparison -- object
1402directories are created in a separate object directory tree, and a
1403symlink to the object directory in that tree is created in the source
1404directory; otherwise, "make obj" assumes that you're not in the main
1405source tree and that it's not safe to use a separate object tree.
1406
1407Several variables used by <bsd.obj.mk> control exactly what
1408directories and links get created during a "make obj":
1409
1410MAKEOBJDIR	If set, this is the component name of the object
1411		directory.
1412
1413OBJMACHINE	If this is set but MAKEOBJDIR is not set, creates
1414		object directories or links named "obj.${MACHINE}";
1415		otherwise, just creates ones named "obj".
1416
1417USR_OBJMACHINE  If set, and the current directory is a subdirectory of
1418		${BSDSRCDIR}, create object directory in the
1419		corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1420		otherwise, create it in the corresponding subdirectory
1421		of ${BSDOBJDIR}
1422
1423BUILDID		If set, the contents of this variable are appended
1424		to the object directory name.  If OBJMACHINE is also
1425		set, ".${BUILDID}" is added after ".${MACHINE}".
1426
1427
1428=-=-=-=-=   bsd.prog.mk   =-=-=-=-=
1429
1430The include file <bsd.prog.mk> handles building programs from one or
1431more source files, along with their manual pages.  It has a limited number
1432of suffixes, consistent with the current needs of the BSD tree.
1433<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1434
1435It has eight targets:
1436
1437	all:
1438		build the program and its manual page.  This also
1439		creates a GDB initialization file (.gdbinit) in
1440		the objdir.  The .gdbinit file sets the shared library
1441		prefix to ${DESTDIR} to facilitate cross-debugging.
1442	clean:
1443		remove the program, any object files and the files a.out,
1444		Errs, errs, mklog, and ${PROG}.core.
1445	cleandir:
1446		remove all of the files removed by the target clean, as
1447		well as .depend, tags, and any manual pages.
1448		`distclean' is a synonym for `cleandir'.
1449	depend:
1450		make the dependencies for the source files, and store
1451		them in the file .depend.
1452	includes:
1453		install any header files.
1454	install:
1455		install the program and its manual pages; if the Makefile
1456		does not itself define the target install, the targets
1457		beforeinstall and afterinstall may also be used to cause
1458		actions immediately before and after the install target
1459		is executed.
1460	lint:
1461		run lint on the source files
1462	tags:
1463		create a tags file for the source files.
1464
1465It sets/uses the following variables:
1466
1467BINGRP		Binary group.
1468
1469BINOWN		Binary owner.
1470
1471BINMODE		Binary mode.
1472
1473CLEANDIRFILES	Additional files to remove for the cleandir target.
1474
1475CLEANFILES	Additional files to remove for the clean and cleandir targets.
1476
1477CONFIGOPTS	Additional flags to config(1) when building kernels.
1478
1479COPTS		Additional flags to the compiler when creating C objects.
1480
1481COPTS.<fn>	Additional flags to the compiler when creating the
1482		C objects for <fn>.
1483		For <fn>.[ly], "<fn>.c" must be used.
1484
1485CPUFLAGS	Additional flags to the compiler/assembler to select
1486		CPU instruction set options, CPU tuning options, etc.
1487
1488CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1489		For <fn>.[ly], "<fn>.c" must be used.
1490
1491CPPFLAGS	Additional flags to the C pre-processor.
1492
1493CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1494		For <fn>.[ly], "<fn>.c" must be used.
1495
1496GDBINIT		List of GDB initialization files to add to "source"
1497		directives in the .gdbinit file that is created in the
1498		objdir.
1499
1500LDADD		Additional loader objects.  Usually used for libraries.
1501		For example, to load with the compatibility and utility
1502		libraries, use:
1503
1504			LDADD+=-lutil -lcompat
1505
1506LDFLAGS		Additional linker flags (passed to ${CC} during link).
1507
1508LINKS		See <bsd.links.mk>
1509
1510OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1511
1512OBJCOPTS.<fn>	Additional flags to the compiler when creating the
1513		ObjC objects for <fn>.
1514		For <fn>.[ly], "<fn>.c" must be used.
1515
1516SYMLINKS	See <bsd.links.mk>
1517
1518MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1519		defined, "MAN=${PROG}.1" is assumed.
1520
1521PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1522		time, with the value of this variable as args to paxctl(1).
1523
1524PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1525
1526PROG		The name of the program to build.  If not supplied, nothing
1527		is built.
1528
1529PROG_CXX	If defined, the name of the program to build.  Also
1530		causes <bsd.prog.mk> to link the program with the C++
1531		compiler rather than the C compiler.  PROG_CXX overrides
1532		the value of PROG if PROG is also set.
1533
1534PROGNAME	The name that the above program will be installed as, if
1535		different from ${PROG}.
1536
1537SRCS		List of source files to build the program.  If SRCS is not
1538		defined, it's assumed to be ${PROG}.c.
1539
1540DPSRCS		List of source files which are needed for generating
1541		dependencies, but are not needed in ${SRCS}.
1542
1543DPADD		Additional dependencies for the program.  Usually used for
1544		libraries.  For example, to depend on the compatibility and
1545		utility libraries use:
1546
1547			DPADD+=${LIBCOMPAT} ${LIBUTIL}
1548

1700SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1701		strings, using xstr(1). Note that this will not work with
1702		parallel makes.
1703
1704STRIPFLAG	The flag passed to the install program to cause the binary
1705		to be stripped.
1706
1707SUBDIR		A list of subdirectories that should be built as well.
1708		Each of the targets will execute the same target in the
1709		subdirectories.
1710
1711SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1712		These are installed exactly like programs.
1713
1714SCRIPTSDIR	The location to install the scripts.  Each script can be
1715		installed to a separate path by setting SCRIPTSDIR_<script>.
1716
1717SCRIPTSNAME	The name that the above program will be installed as, if
1718		different from ${SCRIPTS}. These can be further specialized
1719		by setting SCRIPTSNAME_<script>.
1720
1721FILES		See description of <bsd.files.mk>.
1722
1723SHLINKDIR	Target directory for shared linker.  See description of
1724		<bsd.own.mk> for additional information about this variable.
1725
1726The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1727if it exists, as well as the include file <bsd.man.mk>.
1728
1729Some simple examples:
1730
1731To build foo from foo.c with a manual page foo.1, use:
1732
1733	PROG=	foo
1734
1735	.include <bsd.prog.mk>
1736
1737To build foo from foo.c with a manual page foo.2, add the line:
1738
1739	MAN=	foo.2
1740
1741If foo does not have a manual page at all, add the line:
1742
1743	MKMAN=	no
1744
1745If foo has multiple source files, add the line:
1746
1747	SRCS=	a.c b.c c.c d.c
1748
1749
1750=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1751
1752The include file <bsd.rpc.mk> contains a makefile fragment used to
1753construct source files built by rpcgen.
1754
1755The following macros may be defined in makefiles which include
1756<bsd.rpc.mk> in order to control which files get built and how they
1757are to be built:
1758
1759RPC_INCS:	construct .h file from .x file
1760RPC_XDRFILES:	construct _xdr.c from .x file
1761		(for marshalling/unmarshalling data types)
1762RPC_SVCFILES:	construct _svc.c from .x file
1763		(server-side stubs)
1764RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1765
1766RPC_XDIR:	Directory containing .x/.h files
1767
1768
1769=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1770
1771The include file <bsd.shlib.mk> computes parameters for shared library
1772installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1773included before <bsd.shlib.mk>.
1774
1775<bsd.own.mk> sets the following variables, if they are not already defined
1776(defaults are in brackets):
1777
1778SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1779		instead of ${LIBDIR} as the base path for shared library
1780		installation.  [/lib]
1781
1782SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1783		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1784		for all others.]
1785
1786_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1787		otherwise set to ${LIBDIR}
1788
1789SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1790
1791SHLINKDIR	Path to use for shared linker when building a program.
1792		[/libexec for programs in /bin and /sbin, /usr/libexec for
1793		all others.]
1794
1795
1796=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1797
1798The include file <bsd.subdir.mk> contains the default targets for building
1799subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1800clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1801following variables:
1802
1803NOSUBDIR	If this variable is defined, then the SUBDIR variable
1804		will be ignored and subdirectories will not be processed.
1805
1806SUBDIR		For all of the directories listed in ${SUBDIR}, the
1807		specified directory will be visited and the target made.
1808
1809		As a special case, the use of a token .WAIT as an
1810		entry in SUBDIR acts as a synchronization barrier
1811		when multiple make jobs are run; subdirs before the
1812		.WAIT must complete before any subdirs after .WAIT are
1813		started.  See make(1) for some caveats on use of .WAIT
1814		and other special sources.
1815
1816
1817=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1818
1819The include file <bsd.x11.mk> contains parameters and targets for
1820cross-building X11 from ${X11SRCDIR.<package>}.  It should be included
1821after the general Makefile contents but before the include files such as
1822<bsd.prog.mk> and <bsd.lib.mk>.
1823
1824It provides the following targets:
1825	.man.1 .man.3 .man.4 .man.5 .man.7:
1826		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1827		these rules convert from X11's manual page source
1828		into an mdoc.old source file.
1829
1830It sets the following variables:
1831
1832BINDIR			Set to ${X11BINDIR}.
1833			To override, define after including <bsd.x11.mk>
1834
1835LIBDIR			Set to ${X11USRLIBDIR}.
1836			To override, define after including <bsd.x11.mk>
1837
1838MANDIR			Set to ${X11MANDIR}.
1839			To override, define after including <bsd.x11.mk>
1840
1841CPPFLAGS		Appended with definitions to include from
1842			${DESTDIR}${X11INCDIR}
1843
1844LDFLAGS			Appended with definitions to link from
1845			${DESTDIR}${X11USRLIBDIR}
1846
1847X11FLAGS.CONNECTION	Equivalent to X11's CONNECTION_FLAGS.
1848
1849X11FLAGS.EXTENSION	Equivalent to X11's EXT_DEFINES.
1850
1851X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1852
1853X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1854
1855X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1856
1857X11FLAGS.THREADLIB	Equivalent to X11's THREADS_DEFINES for libraries.
1858
1859X11FLAGS.THREADS	Equivalent to X11's THREADS_DEFINES.
1860
1861X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1862
1863X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1864
1865X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1866
1867It uses the following variables:
1868
1869APPDEFS			List of app-default files to install.
1870
1871CPPSCRIPTS		List of files/scripts to run through cpp(1)
1872			and then ${X11TOOL_UNXCOMM}.  The source files
1873			have a `.cpp' suffix, the generated files do not.
1874
1875CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1876
1877CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.
1878

1880=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1881
1882The following files are described here for completion, but they are not
1883supposed to be included directly from other Makefiles; they are used
1884internally by other system files.
1885
1886=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1887
1888The include file <bsd.sys.mk> is used by other system mk files and
1889it is not intended to be included standalone. It contains rules and
