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.

12
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
124
125MKBINUTILS	If "no", don't build binutils (gas, ld, etc and libbfd,

390		non-root "make install".
391		Default: no
392
393MKUPDATE 	If not "no", 'make install' only installs targets that are
394		more recently modified in the source directories that their

442
443USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
444		designed for improved performance with threaded
445		applications.  The "phkmalloc" allocator as used up
446		before NetBSD-5.0 will be substituted.
447
448USE_KERBEROS	If "no", disables building Kerberos v5
449		support into various system utilities/libraries that

466
467USE_SSP		If "no", disables GCC stack protection code, which
468		detects stack overflows and aborts the program. The
469		stack protection code imposes a performance penalty
470		of about 5%.
471		Default: "no", unless "USE_FORT" is set to "yes"
472
473USE_FORT 	If "yes" turns on substitute wrappers for commonly used
474		functions that do not do bounds checking regularly, but
475		they could in some cases by using the gcc
476		__builtin_object_size() function to determine the buffer
477		size where it is known and detect buffer overflows.
478		These substitute functions are in /usr/include/ssp.
479		Default: depends on the part of the source tree
480
481USE_YP		If "no", disables building YP (NIS) support into
482		various system utilities/libraries that support it.
483		If ${MKYP} is "no", USE_YP will also be forced to "no".

491		XFree86 or modular Xorg.  Only matters if MKX11!=no.
492		Default: "Xorg" on amd64, i386, macppc, shark and sparc64,
493		"XFree86" on everything else.

495COPTS.lib<lib>
496OBJCOPTS.lib<lib>
497LDADD.lib<lib>
498CPPFLAGS.lib<lib>
499CXXFLAGS.lib<lib>
500COPTS.<prog>
501OBJCCOPTS.<prog>
502LDADD.<prog>
503CPPFLAGS.<prog>
504CXXFLAGS.<prog>	These provide a way to specify additions to the associated
505		variables in a way that applies only to a particular library
506		or program.  <lib> corresponds to the LIB variable set in
507		the library's makefile.  <prog> corresponds to either PROG
508		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
509		set to "-g", "-g" will be added to COPTS only when compiling
510		the crypto library.
511
512The active compiler is selected using the following variables:
513AVAILABLE_COMPILER
514		List of available compiler suites.  Processed in order
515		for selecting the active compiler for each frontend.
516HAVE_PCC	If defined, PCC is present and enabled.
517HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
518UNSUPPORTED_COMPILER.xxx
519		If defined, the support for compiler "xxx" is disabled.
520
521For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
522ACTIVE_CC	Active compile suite for the CC frontend.
523SUPPORTED_CC	Compile suite with support for the CC frontend.
524TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
525
526=-=-=-=-=   sys.mk   =-=-=-=-=
527
528The include file <sys.mk> has the default rules for all makes, in the BSD
529environment or otherwise.  You probably don't want to touch this file.
530
531=-=-=-=-=   bsd.own.mk   =-=-=-=-=
532
533The include file <bsd.own.mk> contains source tree configuration parameters,
534such as the owners, groups, etc. for both manual pages and binaries, and
535a few global "feature configuration" parameters.
536
537It has no targets.
538
539To get system-specific configuration parameters, <bsd.own.mk> will try to
540include the file specified by the "MAKECONF" variable.  If MAKECONF is not
541set, or no such file exists, the system make configuration file, /etc/mk.conf
542is included.  These files may define any of the variables described below.
543
544<bsd.own.mk> sets the following variables, if they are not already defined
545(defaults are in brackets):
546
547NETBSDSRCDIR	Top of the NetBSD source tree.
548		If _SRC_TOP_ != "", that will be used as the default,
549		otherwise BSDSRCDIR will be used as the default.
550		Various makefiles within the NetBSD source tree will
551		use this to reference the top level of the source tree.
552
553_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
554		based on the presence of tools/ and build.sh.  This variable
555		is "internal" to <bsd.own.mk>, although its value is only
556		determined once and then propagated to all sub-makes.
557
558_NETBSD_VERSION_DEPENDS
559		A list of files which contain information about
560		the version of the NetBSD being built.  This is
561		defined only if the current directory appears
562		to be inside a NetBSD source tree.  The list of
563		files includes ${NETBSDSRCDIR}/sys/sys/param.h
564		(which contains the kernel version number),
565		${NETBSDSRCDIR}/sys/conf/newvers.sh and
566		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
567		interpret the information in sys/sys/param.h), and
568		${_SRC_TOP_OBJ_}/params (which is an optional file,
569		created by "make build" in ${_SRC_TOP_}/Makefile,
570		containing all the variables that may influence the
571		build).
572
573		Targets that depend on the NetBSD version, or on
574		variables defined at build time, can declare a
575		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
576
577			version.c: ${_NETBSD_VERSION_DEPENDS}
578				commands to create version.c
579
580BSDSRCDIR	The real path to the system sources, so that 'make obj'
581		will work correctly.  [/usr/src]
582

670		to be stripped.  This is to be used when building your
671		own install script so that the entire system can be made
672		stripped/not-stripped using a single knob.  []
673
674COPY		The flag passed to the install program to cause the binary
675		to be copied rather than moved.  This is to be used when
676		building our own install script so that the entire system
677		can either be installed with copies, or with moves using
678		a single knob.  [-c]
679
680MAKEDIRTARGETENV
681		Environment variables passed to the child make process
682		invoked by MAKEDIRTARGET.
683
684MAKEDIRTARGET dir target [params]
685		Runs "cd $${dir} && ${MAKE} [params] $${target}",
686		displaying a "pretty" message whilst doing so.
687
688RELEASEMACHINEDIR
689		Subdirectory used below RELEASEDIR when building
690		a release.  [${MACHINE}]
691
692RELEASEMACHINE	Subdirectory or path component used for the following
693		paths:
694			distrib/${RELEASEMACHINE}
695			distrib/notes/${RELEASEMACHINE}
696			etc/etc.${RELEASEMACHINE}
697		Used when building a release.  [${MACHINE}]
698
699Additionally, the following variables may be set by <bsd.own.mk> or in a
700make configuration file to modify the behavior of the system build
701process (default values are in brackets along with comments, if set by
702<bsd.own.mk>):
703
704USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
705		be used as part of a build in progress.
706		Supported values:
707
708		yes	Use the tools from TOOLDIR.
709			Must be set to this if cross-compiling.
710
711		no	Do not use the tools from TOOLDIR, but refuse to
712			build native compilation tool components that are
713			version-specific for that tool.
714
715		never	Do not use the tools from TOOLDIR, even when
716			building native tool components.  This is similar to
717			the traditional NetBSD build method, but does not
718			verify that the compilation tools in use are
719			up-to-date enough in order to build the tree
720			successfully.  This may cause build or runtime
721			problems when building the whole NetBSD source tree.
722
723		Default: "yes" if building all or part of a whole NetBSD
724		source tree (detected automatically); "no" otherwise
725		(to preserve traditional semantics of the <bsd.*.mk>
726		make(1) include files).
727
728OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
729		use ELF -- currently all architectures].
730
731TOOLCHAIN_MISSING
732		If not "no", this indicates that the platform being built
733		does not have a working in-tree toolchain.  If the
734		${MACHINE_ARCH} in question falls into this category,
735		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
736		Otherwise, the variable is unconditionally assigned the
737		value "no".
738		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
739		unconditionally assigned the value "no".
740
741EXTERNAL_TOOLCHAIN
742		This variable is not directly set by <bsd.own.mk>, but
743		including <bsd.own.mk> is the canonical way to gain
744		access to this variable.  The variable should be defined
745		either in the user's environment or in the user's mk.conf
746		file.  If defined, this variable indicates the root of
747		an external toolchain which will be used to build the
748		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
749		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
750		cross-compile framework.
751
752		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
753		assigned the value "no", since the external version of the
754		compiler may not be able to build the library components of
755		the in-tree compiler.
756
757		NOTE: This variable is not yet used in as many places as
758		it should be.  Expect the exact semantics of this variable
759		to change in the short term as parts of the cross-compile
760		framework continue to be cleaned up.
761
762The following variables are defined to commands to perform the
763appropriate operation, with the default in [brackets].  Note that
764the defaults change if USETOOLS == "yes":
765
766TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

916
917<bsd.own.mk> is generally useful when building your own Makefiles so that
918they use the same default owners etc. as the rest of the tree.
919
920
921=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
922
923The include file <bsd.clean.mk> defines the clean and cleandir
924targets.  It uses the following variables:
925
926CLEANFILES	Files to remove for both the clean and cleandir targets.
927
928CLEANDIRFILES	Files to remove for the cleandir target, but not for
929		the clean target.
930
931MKCLEANSRC	Controls whether or not the clean and cleandir targets
932		will delete files from both the object directory,
933		${.OBJDIR}, and the source directory, ${.CURDIR}.
934
935		If MKCLEANSRC is set to "no", then the file names in
936		CLEANFILES or CLEANDIRFILES are interpreted relative
937		to the object directory, ${.OBJDIR}.  This is the
938		traditional behaviour.
939
940		If MKCLEANSRC is set to "yes", then the file deletion
941		is performed relative to both the object directory,
942		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
943		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
944		Deleting files from ${.CURDIR} is intended to remove
945		stray output files that had been left in the source
946		directory by an earlier build that did not use object
947		directories.
948
949		The default is MKCLEANSRC=yes.  If you always build with
950		separate object directories, and you are sure that there
951		are no stray files in the source directories, then you
952		may set MKCLEANSRC=no to save some time.
953
954MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
955		will verify that files have been deleted.
956
957		If MKCLEANVERIFY is set to "no", then the files will
958		be deleted using a "rm -f" command, and its success or
959		failure will be ignored.
960
961		If MKCLEANVERIFY is set to "yes", then the success of
962		the "rm -f" command will be verified using an "ls"
963		command.
964
965		The default is MKCLEANVERIFY=yes.  If you are sure that
966		there will be no problems caused by file permissions,
967		read-only file systems, or the like, then you may set
968		MKCLEANVERIFY=no to save some time.
969
970To use the clean and cleandir targets defined in <bsd.clean.mk>, other
971Makefiles or bsd.*.mk files should append file names to the CLEANFILES
972or CLEANDIRFILES variables.  For example:
973
974	    CLEANFILES+= a.out
975	    CLEANDIRFILES+= .depend
976
977	    .include <bsd.clean.mk>
978
979The files listed in CLEANFILES and CLEANDIRFILES must not be
980directories, because the potential risk from running "rm -rf" commands
981in bsd.clean.mk is considered too great.  If you want to recursively
982delete a directory as part of "make clean" or "make cleandir" then you
983need to provide your own target.
984
985=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
986
987The include file <bsd.dep.mk> contains the default targets for building
988.depend files.  It creates .d files from entries in SRCS and DPSRCS
989that are C, C++, or Objective C source files, and builds .depend from the
990.d files.  All other files in SRCS and all of DPSRCS will be used as
991dependencies for the .d files.  In order for this to function correctly,
992it should be .included after all other .mk files and directives that may
993modify SRCS or DPSRCS.  It uses the following variables:
994
995SRCS		List of source files to build the program.
996
997DPSRCS		List of source files which are needed for generating
998		dependencies, but are not needed in ${SRCS}.
999

1001=-=-=-=-=   bsd.files.mk   =-=-=-=-=
1002
1003The include file <bsd.files.mk> handles the FILES variables and is included
1004from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1005
1006FILES		The list of files to install.
1007
1008CONFIGFILES	Similar semantics to FILES, except that the files
1009		are installed by the `configinstall' target,
1010		not the `install' target.
1011		The FILES* variables documented below also apply.
1012
1013FILESOWN	File owner.  [${BINOWN}]
1014
1015FILESGRP	File group.  [${BINGRP}]
1016
1017FILESMODE	File mode.  [${NONBINMODE}]
1018
1019FILESDIR	The location to install the files.
1020
1021FILESNAME	Optional name to install each file as.
1022
1023FILESOWN_<fn>	File owner of the specific file <fn>.
1024
1025FILESGRP_<fn>	File group of the specific file <fn>.
1026
1027FILESMODE_<fn>	File mode of the specific file <fn>.
1028
1029FILESDIR_<fn>	The location to install the specific file <fn>.
1030
1031FILESNAME_<fn>	Optional name to install <fn> as.
1032
1033FILESBUILD	If this variable is defined, then its value will be
1034		used as the default for all FILESBUILD_<fn> variables.
1035		Otherwise, the default will be "no".
1036
1037FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1038		targets to be built by `realall'.  Users of that variable
1039		should provide a target to build the file.
1040
1041
1042BUILDSYMLINKS	List of two word items:
1043			lnsrc lntgt
1044		For each lnsrc item, create a symlink named lntgt.
1045		The lntgt symlinks are removed by the cleandir target.
1046
1047UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1048		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1049		The source files have a `.uue' suffix, the generated files do
1050		not.
1051
1052UUDECODE_FILES_RENAME_<fn>
1053		Rename the output from the decode to the provided name.
1054		
1055		*NOTE: These files are simply decoded, with no install or other
1056		       rule applying implicitly except being added to the clean
1057		       target.

1061The include file <bsd.gcc.mk> computes various parameters related to GCC
1062support libraries.  It defines no targets.  <bsd.own.mk> MUST be included
1063before <bsd.gcc.mk>.
1064
1065The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
1066of which need to know where to find certain GCC support libraries.
1067
1068The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
1069which is generally set by the user.  If EXTERNAL_TOOLCHAIN it set, then
1070the compiler is asked where to find the support libraries, otherwise the
1071support libraries are found in ${DESTDIR}/usr/lib.
1072
1073<bsd.gcc.mk> sets the following variables:
1074
1075_GCC_CRTBEGIN	The full path name to crtbegin.o.
1076
1077_GCC_CRTBEGINS	The full path name to crtbeginS.o.
1078
1079_GCC_CRTEND	The full path name to crtend.o.
1080
1081_GCC_CRTENDS	The full path name to crtendS.o.
1082
1083_GCC_LIBGCCDIR	The directory where libgcc.a is located.
1084
1085
1086=-=-=-=-=   bsd.inc.mk   =-=-=-=-=
1087
1088The include file <bsd.inc.mk> defines the includes target and uses the
1089variables:
1090
1091INCS		The list of include files.
1092
1093INCSDIR		The location to install the include files.
1094
1095INCSNAME	Target name of the include file, if only one; same as
1096		FILESNAME, but for include files.
1097
1098INCSYMLINKS	Similar to SYMLINKS in <bsd.links.mk>, except that these
1099		are installed in the 'includes' target and not the
1100		(much later) 'install' target.
1101
1102INCSNAME_<file>	The name file <file> should be installed as, if not <file>,
1103		same as FILESNAME_<file>, but for include files.
1104
1105
1106=-=-=-=-=   bsd.info.mk   =-=-=-=-=
1107
1108The include file <bsd.info.mk> is used to generate and install GNU Info
1109documentation from respective Texinfo source files.  It defines three
1110implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
1111following variables:
1112
1113TEXINFO		List of Texinfo source files.  Info documentation will
1114		consist of single files with the extension replaced by
1115		.info.
1116
1117INFOFLAGS	Flags to pass to makeinfo.  []
1118
1119
1120=-=-=-=-=   bsd.kernobj.mk   =-=-=-=-=
1121
1122The include file <bsd.kernobj.mk> defines variables related to the
1123location of kernel sources and object directories.
1124
1125KERNSRCDIR	Is the location of the top of the kernel src.
1126		[${_SRC_TOP_}/sys]
1127
1128KERNARCHDIR	Is the location of the machine dependent kernel sources.
1129		[arch/${MACHINE}]
1130
1131KERNCONFDIR	Is where the configuration files for kernels are found.
1132		[${KERNSRCDIR}/${KERNARCHDIR}/conf]
1133
1134KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
1135		instance will be compiled in ${KERNOBJDIR}/GENERIC.
1136		The default value is
1137		${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
1138		if it exists or the target 'obj' is being made.
1139		Otherwise the default is
1140		${KERNSRCDIR}/${KERNARCHDIR}/compile.
1141
1142It is important that Makefiles (such as those under src/distrib) that
1143wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
1144rather than make assumptions about the location of the compiled kernel.
1145
1146
1147=-=-=-=-=   bsd.kinc.mk   =-=-=-=-=
1148
1149The include file <bsd.kinc.mk> defines the many targets (includes,
1150subdirectories, etc.), and is used by kernel makefiles to handle
1151include file installation.  It is intended to be included alone, by
1152kernel Makefiles.  It uses similar variables to <bsd.inc.mk>.
1153Please see <bsd.kinc.mk> for more details, and keep the documentation
1154in that file up to date.
1155
1156=-=-=-=-=   bsd.syscall.mk =-=-=-=-=
1157
1158The include file <bsd.syscall.mk> contains the logic to create syscall
1159files for various emulations. It includes <bsd.kinc.mk> to handle the
1160rest of the targets.
1161
1162=-=-=-=-=   bsd.lib.mk   =-=-=-=-=
1163
1164The include file <bsd.lib.mk> has support for building libraries.  It has
1165the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1166includes, install, lint, and tags.  Additionally, it has a checkver target
1167which checks for installed shared object libraries whose version is greater
1168that the version of the source. It has a limited number of suffixes,
1169consistent with the current needs of the BSD tree.  <bsd.lib.mk> includes
1170<bsd.shlib.mk> to get shared library parameters.
1171
1172It sets/uses the following variables:
1173
1174LIB		The name of the library to build.
1175
1176LIBDIR		Target directory for libraries.
1177
1178MKARZERO	Normally, ar(1) sets the timestamps, uid, gid and
1179		permissions in files inside its archives to those of
1180		the file it was fed. This leads to non-reproduceable
1181		builds. If MKARZERO is set to "yes" (default is the
1182		same as MKREPRO, or "no" if MKREPRO is not defined),
1183		then the "D" flag is passed to ar, causing the
1184		timestamp, uid and gid to be zeroed and the file
1185		permissions to be set to 644. This allows .a files
1186		from different builds to be bit identical.
1187
1188SHLIBINSTALLDIR	Target directory for shared libraries if ${USE_SHLIBDIR}
1189		is not "no".
1190
1191SHLIB_MAJOR
1192SHLIB_MINOR
1193SHLIB_TEENY	Major, minor, and teeny version numbers of shared library
1194
1195USE_SHLIBDIR	If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
1196		as the path to install shared libraries to.
1197		USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
1198		Default: no
1199
1200LIBISMODULE	If not "no", install as ${LIB}.so (without the "lib" prefix),
1201		and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
1202		MKPROFILE=no MKSTATICLIB=no".
1203		Default: no
1204
1205LIBISPRIVATE	If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
1206		MKPROFILE=no", and don't install the (.a) library.
1207		This is useful for "build only" helper libraries.
1208		Default: no
1209
1210LIBISCXX	If not "no", Use ${CXX} instead of ${CC} to link
1211		shared libraries.
1212		This is useful for C++ libraries.
1213		Default: no
1214
1215LINTLIBDIR	Target directory for lint libraries.
1216
1217LIBGRP		Library group.
1218
1219LIBOWN		Library owner.
1220
1221LIBMODE		Library mode.
1222
1223LDADD		Additional loader objects.
1224
1225MAN		The manual pages to be installed (use a .1 - .9 suffix).
1226
1227NOCHECKVER_<library>
1228NOCHECKVER	If set, disables checking for installed shared object
1229		libraries with versions greater than the source.  A
1230		particular library name, without the "lib" prefix, may
1231		be appended to the variable name to disable the check for
1232		only that library.
1233
1234SRCS		List of source files to build the library.  Suffix types
1235		.s, .c, and .f are supported.  Note, .s files are preferred
1236		to .c files of the same name.  (This is not the default for
1237		versions of make.)
1238
1239LIBDPLIBS	A list of the tuples:
1240			libname  path-to-srcdir-of-libname
1241
1242		For each tuple;
1243		     *	LIBDO.libname contains the .OBJDIR of the library
1244			`libname', and if it is not set it is determined
1245			from the srcdir and added to MAKEOVERRIDES (the
1246			latter is to allow for build time optimization).
1247		     *	LDADD gets  -L${LIBDO.libname} -llibname    added.
1248		     *	DPADD gets  ${LIBDO.libname}/liblibname.so  or
1249				    ${LIBDO.libname}/liblibname.a   added.
1250
1251		The special value "_external" for LIBDO.lib makes the
1252		build system to assume the library comes from outside
1253		of the NetBSD source tree and only causes -llibname
1254		to be added to LDADD.
1255
1256		This variable may be used for individual libraries, as
1257		well as in parent directories to cache common libraries
1258		as a build-time optimization.
1259
1260The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1261if it exists, as well as the include file <bsd.man.mk>.
1262
1263It has rules for building profiled objects; profiled libraries are
1264built by default.
1265
1266Libraries are ranlib'd when made.
1267
1268
1269=-=-=-=-=   bsd.links.mk   =-=-=-=-=
1270
1271The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1272and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1273
1274LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1275is used. The defaults may be modified by other bsd.*.mk files which
1276include bsd.links.mk.  In the future, these variables may be replaced
1277by a method for explicitly recording hard links in a metadata log.
1278
1279LINKS		The list of hard links, consisting of pairs of paths:
1280			source-file target-file
1281		${DESTDIR} is prepended to both paths before linking.
1282		For example, to link /bin/test and /bin/[, use:
1283			LINKS=/bin/test /bin/[
1284
1285CONFIGLINKS	Similar semantics to LINKS, except that the links
1286		are installed by the `configinstall' target,
1287		not the `install' target.
1288
1289SYMLINKS	The list of symbolic links, consisting of pairs of paths:
1290			source-file target-file
1291		${DESTDIR} is only prepended to target-file before linking.
1292		For example, to symlink /usr/bin/tar to /bin/tar resulting
1293		in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1294			SYMLINKS=/bin/tar /usr/bin/tar
1295
1296CONFIGSYMLINKS	Similar semantics to SYMLINKS, except that the symbolic links
1297		are installed by the `configinstall' target,
1298		not the `install' target.
1299
1300LINKSOWN	Link owner.  [${BINOWN}]
1301
1302LINKSGRP	Link group.  [${BINGRP}]
1303
1304LINKSMODE	Link mode.  [${NONBINMODE}]
1305
1306LINKSOWN_<fn>	Link owner of the specific file <fn>.
1307
1308LINKSGRP_<fn>	Link group of the specific file <fn>.
1309
1310LINKSMODE_<fn>	Link mode of the specific file <fn>.
1311
1312
1313=-=-=-=-=   bsd.man.mk   =-=-=-=-=
1314
1315The include file <bsd.man.mk> handles installing manual pages and their
1316links.
1317
1318It has a three targets:
1319
1320	catinstall:
1321		Install the preformatted manual pages and their links.
1322	htmlinstall:
1323		Install the HTML manual pages and their links.
1324	maninstall:
1325		Install the manual page sources and their links.
1326
1327It sets/uses the following variables:
1328
1329MANDIR		Base path for manual installation.
1330
1331MANGRP		Manual group.
1332
1333MANOWN		Manual owner.
1334
1335MANMODE		Manual mode.
1336
1337MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
1338		or "/tahoe" for machine specific manual pages.
1339
1340MAN		The manual pages to be installed (use a .1 - .9 suffix).
1341
1342MLINKS		List of manual page links (using a .1 - .9 suffix).  The
1343		linked-to file must come first, the linked file second,
1344		and there may be multiple pairs.
1345
1346The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1347it exists.
1348
1349
1350=-=-=-=-=   bsd.obj.mk   =-=-=-=-=
1351
1352The include file <bsd.obj.mk> defines targets related to the creation
1353and use of separated object and source directories.
1354
1355If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1356${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1357it exists.  Otherwise make(1) looks for the existence of a
1358subdirectory (or a symlink to a directory) of the source directory
1359into which built targets should be placed.  If an environment variable
1360named MAKEOBJDIR is set, make(1) uses its value as the name of the
1361object directory; failing that, make first looks for a subdirectory
1362named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1363
1364Object directories are not created automatically by make(1) if they
1365don't exist; you need to run a separate "make obj".  (This will happen
1366during a top-level build if "MKOBJDIRS" is set to a value other than
1367"no").  When the source directory is a subdirectory of ${BSDSRCDIR} --
1368and this is determined by a simple string prefix comparison -- object
1369directories are created in a separate object directory tree, and a
1370symlink to the object directory in that tree is created in the source
1371directory; otherwise, "make obj" assumes that you're not in the main
1372source tree and that it's not safe to use a separate object tree.
1373
1374Several variables used by <bsd.obj.mk> control exactly what
1375directories and links get created during a "make obj":
1376
1377MAKEOBJDIR	If set, this is the component name of the object
1378		directory.
1379
1380OBJMACHINE	If this is set but MAKEOBJDIR is not set, creates
1381		object directories or links named "obj.${MACHINE}";
1382		otherwise, just creates ones named "obj".
1383
1384USR_OBJMACHINE  If set, and the current directory is a subdirectory of
1385		${BSDSRCDIR}, create object directory in the
1386		corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1387		otherwise, create it in the corresponding subdirectory
1388		of ${BSDOBJDIR}
1389
1390BUILDID		If set, the contents of this variable are appended
1391		to the object directory name.  If OBJMACHINE is also
1392		set, ".${BUILDID}" is added after ".${MACHINE}".
1393
1394
1395=-=-=-=-=   bsd.prog.mk   =-=-=-=-=
1396
1397The include file <bsd.prog.mk> handles building programs from one or
1398more source files, along with their manual pages.  It has a limited number
1399of suffixes, consistent with the current needs of the BSD tree.
1400<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1401
1402It has eight targets:
1403
1404	all:
1405		build the program and its manual page.  This also
1406		creates a GDB initialization file (.gdbinit) in
1407		the objdir.  The .gdbinit file sets the shared library
1408		prefix to ${DESTDIR} to facilitate cross-debugging.
1409	clean:
1410		remove the program, any object files and the files a.out,
1411		Errs, errs, mklog, and ${PROG}.core.
1412	cleandir:
1413		remove all of the files removed by the target clean, as
1414		well as .depend, tags, and any manual pages.
1415		`distclean' is a synonym for `cleandir'.
1416	depend:
1417		make the dependencies for the source files, and store
1418		them in the file .depend.
1419	includes:
1420		install any header files.
1421	install:
1422		install the program and its manual pages; if the Makefile
1423		does not itself define the target install, the targets
1424		beforeinstall and afterinstall may also be used to cause
1425		actions immediately before and after the install target
1426		is executed.
1427	lint:
1428		run lint on the source files
1429	tags:
1430		create a tags file for the source files.
1431
1432It sets/uses the following variables:
1433
1434BINGRP		Binary group.
1435
1436BINOWN		Binary owner.
1437
1438BINMODE		Binary mode.
1439
1440CLEANDIRFILES	Additional files to remove for the cleandir target.
1441
1442CLEANFILES	Additional files to remove for the clean and cleandir targets.
1443
1444CONFIGOPTS	Additional flags to config(1) when building kernels.
1445
1446COPTS		Additional flags to the compiler when creating C objects.
1447
1448COPTS.<fn>	Additional flags to the compiler when creating the
1449		C objects for <fn>.
1450		For <fn>.[ly], "<fn>.c" must be used.
1451
1452CPUFLAGS	Additional flags to the compiler/assembler to select
1453		CPU instruction set options, CPU tuning options, etc.
1454
1455CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1456		For <fn>.[ly], "<fn>.c" must be used.
1457
1458CPPFLAGS	Additional flags to the C pre-processor.
1459
1460CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1461		For <fn>.[ly], "<fn>.c" must be used.
1462
1463GDBINIT		List of GDB initialization files to add to "source"
1464		directives in the .gdbinit file that is created in the
1465		objdir.
1466
1467LDADD		Additional loader objects.  Usually used for libraries.
1468		For example, to load with the compatibility and utility
1469		libraries, use:
1470
1471			LDADD+=-lutil -lcompat
1472
1473LDFLAGS		Additional linker flags (passed to ${CC} during link).
1474
1475LINKS		See <bsd.links.mk>
1476
1477OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1478
1479OBJCOPTS.<fn>	Additional flags to the compiler when creating the

1481		For <fn>.[ly], "<fn>.c" must be used.
1482
1483SYMLINKS	See <bsd.links.mk>
1484
1485MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1486		defined, "MAN=${PROG}.1" is assumed.
1487
1488PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1489		time, with the value of this variable as args to paxctl(1).
1490
1491PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1492
1493PROG		The name of the program to build.  If not supplied, nothing
1494		is built.
1495
1496PROG_CXX	If defined, the name of the program to build.  Also
1497		causes <bsd.prog.mk> to link the program with the C++
1498		compiler rather than the C compiler.  PROG_CXX overrides
1499		the value of PROG if PROG is also set.
1500
1501PROGNAME	The name that the above program will be installed as, if
1502		different from ${PROG}.
1503
1504SRCS		List of source files to build the program.  If SRCS is not
1505		defined, it's assumed to be ${PROG}.c.
1506
1507DPSRCS		List of source files which are needed for generating
1508		dependencies, but are not needed in ${SRCS}.
1509
1510DPADD		Additional dependencies for the program.  Usually used for

1667
1668SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1669		strings, using xstr(1). Note that this will not work with
1670		parallel makes.
1671
1672STRIPFLAG	The flag passed to the install program to cause the binary
1673		to be stripped.
1674
1675SUBDIR		A list of subdirectories that should be built as well.
1676		Each of the targets will execute the same target in the
1677		subdirectories.
1678
1679SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1680		These are installed exactly like programs.
1681
1682SCRIPTSDIR	The location to install the scripts.  Each script can be
1683		installed to a separate path by setting SCRIPTSDIR_<script>.
1684
1685SCRIPTSNAME	The name that the above program will be installed as, if
1686		different from ${SCRIPTS}. These can be further specialized
1687		by setting SCRIPTSNAME_<script>.
1688
1689FILES		See description of <bsd.files.mk>.
1690
1691SHLINKDIR	Target directory for shared linker.  See description of
1692		<bsd.own.mk> for additional information about this variable.
1693
1694The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1695if it exists, as well as the include file <bsd.man.mk>.
1696
1697Some simple examples:
1698
1699To build foo from foo.c with a manual page foo.1, use:
1700
1701	PROG=	foo
1702
1703	.include <bsd.prog.mk>
1704
1705To build foo from foo.c with a manual page foo.2, add the line:
1706
1707	MAN=	foo.2
1708
1709If foo does not have a manual page at all, add the line:
1710
1711	MKMAN=	no
1712
1713If foo has multiple source files, add the line:
1714
1715	SRCS=	a.c b.c c.c d.c
1716
1717
1718=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1719
1720The include file <bsd.rpc.mk> contains a makefile fragment used to
1721construct source files built by rpcgen.
1722
1723The following macros may be defined in makefiles which include
1724<bsd.rpc.mk> in order to control which files get built and how they
1725are to be built:
1726
1727RPC_INCS:	construct .h file from .x file
1728RPC_XDRFILES:	construct _xdr.c from .x file
1729		(for marshalling/unmarshalling data types)
1730RPC_SVCFILES:	construct _svc.c from .x file
1731		(server-side stubs)
1732RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1733
1734RPC_XDIR:	Directory containing .x/.h files
1735
1736
1737=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1738
1739The include file <bsd.shlib.mk> computes parameters for shared library
1740installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1741included before <bsd.shlib.mk>.
1742
1743<bsd.own.mk> sets the following variables, if they are not already defined
1744(defaults are in brackets):
1745
1746SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1747		instead of ${LIBDIR} as the base path for shared library
1748		installation.  [/lib]
1749
1750SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1751		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1752		for all others.]
1753
1754_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1755		otherwise set to ${LIBDIR}
1756
1757SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1758
1759SHLINKDIR	Path to use for shared linker when building a program.
1760		[/libexec for programs in /bin and /sbin, /usr/libexec for
1761		all others.]
1762
1763
1764=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1765
1766The include file <bsd.subdir.mk> contains the default targets for building
1767subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1768clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1769following variables:
1770
1771NOSUBDIR	If this variable is defined, then the SUBDIR variable
1772		will be ignored and subdirectories will not be processed.
1773
1774SUBDIR		For all of the directories listed in ${SUBDIR}, the
1775		specified directory will be visited and the target made.
1776
1777		As a special case, the use of a token .WAIT as an
1778		entry in SUBDIR acts as a synchronization barrier
1779		when multiple make jobs are run; subdirs before the
1780		.WAIT must complete before any subdirs after .WAIT are
1781		started.  See make(1) for some caveats on use of .WAIT
1782		and other special sources.
1783
1784
1785=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1786
1787The include file <bsd.x11.mk> contains parameters and targets for
1788cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}.
1789It should be included after the general Makefile contents but before
1790the include files such as <bsd.prog.mk> and <bsd.lib.mk>.
1791
1792It provides the following targets:
1793	.man.1 .man.3 .man.4 .man.5 .man.7:
1794		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1795		these rules convert from X11's manual page source
1796		into an mdoc.old source file.
1797
1798It sets the following variables:
1799
1800BINDIR			Set to ${X11BINDIR}.
1801			To override, define after including <bsd.x11.mk>
1802
1803LIBDIR			Set to ${X11USRLIBDIR}.
1804			To override, define after including <bsd.x11.mk>
1805
1806MANDIR			Set to ${X11MANDIR}.
1807			To override, define after including <bsd.x11.mk>
1808

1810			${DESTDIR}${X11INCDIR}
1811
1812LDFLAGS			Appended with definitions to link from
1813			${DESTDIR}${X11USRLIBDIR}

1819X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1820
1821X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1822
1823X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1824
1825X11FLAGS.THREADLIB	Equivalent to X11's THREADS_DEFINES for libraries.
1826
1827X11FLAGS.THREADS	Equivalent to X11's THREADS_DEFINES.
1828
1829X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1830
1831X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1832
1833X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1834
1835It uses the following variables:
1836
1837APPDEFS			List of app-default files to install.
1838
1839CPPSCRIPTS		List of files/scripts to run through cpp(1)
1840			and then ${X11TOOL_UNXCOMM}.  The source files

1842
1843CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1844
1845CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.

1848=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1849
1850The following files are described here for completion, but they are not
1851supposed to be included directly from other Makefiles; they are used
1852internally by other system files.
1853
1854=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1855
1856The include file <bsd.sys.mk> is used by other system mk files and
1857it is not intended to be included standalone. It contains rules and
