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.

11=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
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

432USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
433		designed for improved performance with threaded
434		applications.  The "phkmalloc" allocator as used up
435		before NetBSD-5.0 will be substituted.
436
437USE_KERBEROS	If "no", disables building Kerberos v5
438		support into various system utilities/libraries that
439		support it.  If ${MKKERBEROS} is "no", USE_KERBEROS
440		will also be forced to "no".
441
442USE_LDAP	If "no", disables building LDAP support into various

454		Default: no
455
456USE_SSP		If "no", disables GCC stack protection code, which

459		of about 5%.
460		Default: "no", unless "USE_FORT" is set to "yes"
461
462USE_FORT 	If "yes" turns on substitute wrappers for commonly used
463		functions that do not do bounds checking regularly, but
464		they could in some cases by using the gcc
465		__builtin_object_size() function to determine the buffer
466		size where it is known and detect buffer overflows.
467		These substitute functions are in /usr/include/ssp.
468		Default: depends on the part of the source tree
469
470USE_YP		If "no", disables building YP (NIS) support into
471		various system utilities/libraries that support it.

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

484COPTS.lib<lib>
485OBJCOPTS.lib<lib>
486LDADD.lib<lib>
487CPPFLAGS.lib<lib>
488CXXFLAGS.lib<lib>
489COPTS.<prog>
490OBJCCOPTS.<prog>
491LDADD.<prog>
492CPPFLAGS.<prog>
493CXXFLAGS.<prog>	These provide a way to specify additions to the associated
494		variables in a way that applies only to a particular library
495		or program.  <lib> corresponds to the LIB variable set in
496		the library's makefile.  <prog> corresponds to either PROG
497		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
498		set to "-g", "-g" will be added to COPTS only when compiling
499		the crypto library.
500
501The active compiler is selected using the following variables:
502AVAILABLE_COMPILER
503		List of available compiler suites.  Processed in order
504		for selecting the active compiler for each frontend.
505HAVE_PCC	If defined, PCC is present and enabled.
506HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
507UNSUPPORTED_COMPILER.xxx
508		If defined, the support for compiler "xxx" is disabled.
509
510For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
511ACTIVE_CC	Active compile suite for the CC frontend.
512SUPPORTED_CC	Compile suite with support for the CC frontend.
513TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
514
515=-=-=-=-=   sys.mk   =-=-=-=-=
516
517The include file <sys.mk> has the default rules for all makes, in the BSD
518environment or otherwise.  You probably don't want to touch this file.
519
520=-=-=-=-=   bsd.own.mk   =-=-=-=-=
521
522The include file <bsd.own.mk> contains source tree configuration parameters,
523such as the owners, groups, etc. for both manual pages and binaries, and
524a few global "feature configuration" parameters.
525
526It has no targets.
527
528To get system-specific configuration parameters, <bsd.own.mk> will try to
529include the file specified by the "MAKECONF" variable.  If MAKECONF is not
530set, or no such file exists, the system make configuration file, /etc/mk.conf
531is included.  These files may define any of the variables described below.
532
533<bsd.own.mk> sets the following variables, if they are not already defined
534(defaults are in brackets):
535
536NETBSDSRCDIR	Top of the NetBSD source tree.
537		If _SRC_TOP_ != "", that will be used as the default,
538		otherwise BSDSRCDIR will be used as the default.
539		Various makefiles within the NetBSD source tree will
540		use this to reference the top level of the source tree.
541
542_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
543		based on the presence of tools/ and build.sh.  This variable
544		is "internal" to <bsd.own.mk>, although its value is only
545		determined once and then propagated to all sub-makes.
546
547_NETBSD_VERSION_DEPENDS
548		A list of files which contain information about
549		the version of the NetBSD being built.  This is
550		defined only if the current directory appears
551		to be inside a NetBSD source tree.  The list of
552		files includes ${NETBSDSRCDIR}/sys/sys/param.h
553		(which contains the kernel version number),
554		${NETBSDSRCDIR}/sys/conf/newvers.sh and
555		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
556		interpret the information in sys/sys/param.h), and
557		${_SRC_TOP_OBJ_}/params (which is an optional file,
558		created by "make build" in ${_SRC_TOP_}/Makefile,
559		containing all the variables that may influence the
560		build).
561
562		Targets that depend on the NetBSD version, or on
563		variables defined at build time, can declare a
564		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
565
566			version.c: ${_NETBSD_VERSION_DEPENDS}
567				commands to create version.c
568
569BSDSRCDIR	The real path to the system sources, so that 'make obj'
570		will work correctly.  [/usr/src]

657STRIPFLAG	The flag passed to the install program to cause the binary
658		to be stripped.  This is to be used when building your
659		own install script so that the entire system can be made
660		stripped/not-stripped using a single knob.  []
661
662COPY		The flag passed to the install program to cause the binary
663		to be copied rather than moved.  This is to be used when
664		building our own install script so that the entire system
665		can either be installed with copies, or with moves using
666		a single knob.  [-c]
667
668MAKEDIRTARGETENV
669		Environment variables passed to the child make process
670		invoked by MAKEDIRTARGET.
671
672MAKEDIRTARGET dir target [params]
673		Runs "cd $${dir} && ${MAKE} [params] $${target}",
674		displaying a "pretty" message whilst doing so.
675
676RELEASEMACHINEDIR
677		Subdirectory used below RELEASEDIR when building
678		a release.  [${MACHINE}]
679
680RELEASEMACHINE	Subdirectory or path component used for the following
681		paths:
682			distrib/${RELEASEMACHINE}
683			distrib/notes/${RELEASEMACHINE}
684			etc/etc.${RELEASEMACHINE}
685		Used when building a release.  [${MACHINE}]
686
687Additionally, the following variables may be set by <bsd.own.mk> or in a
688make configuration file to modify the behavior of the system build
689process (default values are in brackets along with comments, if set by
690<bsd.own.mk>):
691
692USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
693		be used as part of a build in progress.
694		Supported values:
695
696		yes	Use the tools from TOOLDIR.
697			Must be set to this if cross-compiling.
698
699		no	Do not use the tools from TOOLDIR, but refuse to
700			build native compilation tool components that are
701			version-specific for that tool.
702
703		never	Do not use the tools from TOOLDIR, even when
704			building native tool components.  This is similar to
705			the traditional NetBSD build method, but does not
706			verify that the compilation tools in use are
707			up-to-date enough in order to build the tree
708			successfully.  This may cause build or runtime
709			problems when building the whole NetBSD source tree.
710
711		Default: "yes" if building all or part of a whole NetBSD
712		source tree (detected automatically); "no" otherwise
713		(to preserve traditional semantics of the <bsd.*.mk>
714		make(1) include files).
715
716OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
717		use ELF -- currently all architectures].
718
719TOOLCHAIN_MISSING
720		If not "no", this indicates that the platform being built
721		does not have a working in-tree toolchain.  If the
722		${MACHINE_ARCH} in question falls into this category,
723		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
724		Otherwise, the variable is unconditionally assigned the
725		value "no".
726		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
727		unconditionally assigned the value "no".
728
729EXTERNAL_TOOLCHAIN
730		This variable is not directly set by <bsd.own.mk>, but
731		including <bsd.own.mk> is the canonical way to gain
732		access to this variable.  The variable should be defined
733		either in the user's environment or in the user's mk.conf
734		file.  If defined, this variable indicates the root of
735		an external toolchain which will be used to build the
736		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
737		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
738		cross-compile framework.
739
740		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
741		assigned the value "no", since the external version of the
742		compiler may not be able to build the library components of
743		the in-tree compiler.
744
745		NOTE: This variable is not yet used in as many places as
746		it should be.  Expect the exact semantics of this variable
747		to change in the short term as parts of the cross-compile
748		framework continue to be cleaned up.
749
750The following variables are defined to commands to perform the
751appropriate operation, with the default in [brackets].  Note that
752the defaults change if USETOOLS == "yes":
753
754TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

897
898<bsd.own.mk> is generally useful when building your own Makefiles so that
899they use the same default owners etc. as the rest of the tree.
900
901
902=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
903
904The include file <bsd.clean.mk> defines the clean and cleandir
905targets.  It uses the following variables:
906
907CLEANFILES	Files to remove for both the clean and cleandir targets.
908
909CLEANDIRFILES	Files to remove for the cleandir target, but not for
910		the clean target.
911
912MKCLEANSRC	Controls whether or not the clean and cleandir targets
913		will delete files from both the object directory,
914		${.OBJDIR}, and the source directory, ${.CURDIR}.
915
916		If MKCLEANSRC is set to "no", then the file names in
917		CLEANFILES or CLEANDIRFILES are interpreted relative
918		to the object directory, ${.OBJDIR}.  This is the
919		traditional behaviour.
920
921		If MKCLEANSRC is set to "yes", then the file deletion
922		is performed relative to both the object directory,
923		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
924		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
925		Deleting files from ${.CURDIR} is intended to remove
926		stray output files that had been left in the source
927		directory by an earlier build that did not use object
928		directories.
929
930		The default is MKCLEANSRC=yes.  If you always build with
931		separate object directories, and you are sure that there
932		are no stray files in the source directories, then you
933		may set MKCLEANSRC=no to save some time.
934
935MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
936		will verify that files have been deleted.
937
938		If MKCLEANVERIFY is set to "no", then the files will
939		be deleted using a "rm -f" command, and its success or
940		failure will be ignored.
941
942		If MKCLEANVERIFY is set to "yes", then the success of
943		the "rm -f" command will be verified using an "ls"
944		command.
945
946		The default is MKCLEANVERIFY=yes.  If you are sure that
947		there will be no problems caused by file permissions,
948		read-only file systems, or the like, then you may set
949		MKCLEANVERIFY=no to save some time.
950
951To use the clean and cleandir targets defined in <bsd.clean.mk>, other
952Makefiles or bsd.*.mk files should append file names to the CLEANFILES
953or CLEANDIRFILES variables.  For example:
954
955	    CLEANFILES+= a.out
956	    CLEANDIRFILES+= .depend
957
958	    .include <bsd.clean.mk>
959
960The files listed in CLEANFILES and CLEANDIRFILES must not be
961directories, because the potential risk from running "rm -rf" commands
962in bsd.clean.mk is considered too great.  If you want to recursively
963delete a directory as part of "make clean" or "make cleandir" then you
964need to provide your own target.
965
966=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
967
968The include file <bsd.dep.mk> contains the default targets for building
969.depend files.  It creates .d files from entries in SRCS and DPSRCS
970that are C, C++, or Objective C source files, and builds .depend from the
971.d files.  All other files in SRCS and all of DPSRCS will be used as
972dependencies for the .d files.  In order for this to function correctly,
973it should be .included after all other .mk files and directives that may
974modify SRCS or DPSRCS.  It uses the following variables:
975
976SRCS		List of source files to build the program.
977
978DPSRCS		List of source files which are needed for generating
979		dependencies, but are not needed in ${SRCS}.
980
981
982=-=-=-=-=   bsd.files.mk   =-=-=-=-=
983
984The include file <bsd.files.mk> handles the FILES variables and is included
985from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
986
987FILES		The list of files to install.
988
989CONFIGFILES	Similar semantics to FILES, except that the files
990		are installed by the `configinstall' target,
991		not the `install' target.
992		The FILES* variables documented below also apply.
993
994FILESOWN	File owner.  [${BINOWN}]
995
996FILESGRP	File group.  [${BINGRP}]
997
998FILESMODE	File mode.  [${NONBINMODE}]
999
1000FILESDIR	The location to install the files.
1001
1002FILESNAME	Optional name to install each file as.
1003
1004FILESOWN_<fn>	File owner of the specific file <fn>.
1005
1006FILESGRP_<fn>	File group of the specific file <fn>.
1007
1008FILESMODE_<fn>	File mode of the specific file <fn>.
1009
1010FILESDIR_<fn>	The location to install the specific file <fn>.
1011
1012FILESNAME_<fn>	Optional name to install <fn> as.
1013
1014FILESBUILD	If this variable is defined, then its value will be
1015		used as the default for all FILESBUILD_<fn> variables.
1016		Otherwise, the default will be "no".
1017
1018FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1019		targets to be built by `realall'.  Users of that variable
1020		should provide a target to build the file.
1021
1022
1023BUILDSYMLINKS	List of two word items:
1024			lnsrc lntgt
1025		For each lnsrc item, create a symlink named lntgt.
1026		The lntgt symlinks are removed by the cleandir target.
1027
1028UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1029		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1030		The source files have a `.uue' suffix, the generated files do
1031		not.
1032
1033UUDECODE_FILES_RENAME_<fn>
1034		Rename the output from the decode to the provided name.
1035		
1036		*NOTE: These files are simply decoded, with no install or other
1037		       rule applying implicitly except being added to the clean
1038		       target.
1039
1040=-=-=-=-=   bsd.gcc.mk   =-=-=-=-=
1041
1042The include file <bsd.gcc.mk> computes various parameters related to GCC
1043support libraries.  It defines no targets.  <bsd.own.mk> MUST be included
1044before <bsd.gcc.mk>.
1045
1046The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
1047of which need to know where to find certain GCC support libraries.
1048
1049The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
1050which is generally set by the user.  If EXTERNAL_TOOLCHAIN it set, then
1051the compiler is asked where to find the support libraries, otherwise the
1052support libraries are found in ${DESTDIR}/usr/lib.
1053
1054<bsd.gcc.mk> sets the following variables:
1055
1056_GCC_CRTBEGIN	The full path name to crtbegin.o.
1057
1058_GCC_CRTBEGINS	The full path name to crtbeginS.o.
1059
1060_GCC_CRTEND	The full path name to crtend.o.
1061
1062_GCC_CRTENDS	The full path name to crtendS.o.
1063
1064_GCC_LIBGCCDIR	The directory where libgcc.a is located.
1065
1066
1067=-=-=-=-=   bsd.inc.mk   =-=-=-=-=
1068
1069The include file <bsd.inc.mk> defines the includes target and uses the
1070variables:
1071
1072INCS		The list of include files.
1073
1074INCSDIR		The location to install the include files.
1075
1076INCSNAME	Target name of the include file, if only one; same as
1077		FILESNAME, but for include files.
1078
1079INCSYMLINKS	Similar to SYMLINKS in <bsd.links.mk>, except that these
1080		are installed in the 'includes' target and not the
1081		(much later) 'install' target.
1082
1083INCSNAME_<file>	The name file <file> should be installed as, if not <file>,
1084		same as FILESNAME_<file>, but for include files.
1085
1086
1087=-=-=-=-=   bsd.info.mk   =-=-=-=-=
1088
1089The include file <bsd.info.mk> is used to generate and install GNU Info
1090documentation from respective Texinfo source files.  It defines three
1091implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
1092following variables:
1093
1094TEXINFO		List of Texinfo source files.  Info documentation will
1095		consist of single files with the extension replaced by
1096		.info.
1097
1098INFOFLAGS	Flags to pass to makeinfo.  []
1099
1100
1101=-=-=-=-=   bsd.kernobj.mk   =-=-=-=-=
1102
1103The include file <bsd.kernobj.mk> defines variables related to the
1104location of kernel sources and object directories.
1105
1106KERNSRCDIR	Is the location of the top of the kernel src.
1107		[${_SRC_TOP_}/sys]
1108
1109KERNARCHDIR	Is the location of the machine dependent kernel sources.
1110		[arch/${MACHINE}]
1111
1112KERNCONFDIR	Is where the configuration files for kernels are found.
1113		[${KERNSRCDIR}/${KERNARCHDIR}/conf]
1114
1115KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
1116		instance will be compiled in ${KERNOBJDIR}/GENERIC.
1117		The default value is
1118		${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
1119		if it exists or the target 'obj' is being made.
1120		Otherwise the default is
1121		${KERNSRCDIR}/${KERNARCHDIR}/compile.
1122
1123It is important that Makefiles (such as those under src/distrib) that
1124wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
1125rather than make assumptions about the location of the compiled kernel.
1126
1127
1128=-=-=-=-=   bsd.kinc.mk   =-=-=-=-=
1129
1130The include file <bsd.kinc.mk> defines the many targets (includes,
1131subdirectories, etc.), and is used by kernel makefiles to handle
1132include file installation.  It is intended to be included alone, by
1133kernel Makefiles.  It uses similar variables to <bsd.inc.mk>.
1134Please see <bsd.kinc.mk> for more details, and keep the documentation
1135in that file up to date.
1136
1137=-=-=-=-=   bsd.syscall.mk =-=-=-=-=
1138
1139The include file <bsd.syscall.mk> contains the logic to create syscall
1140files for various emulations. It includes <bsd.kinc.mk> to handle the
1141rest of the targets.
1142
1143=-=-=-=-=   bsd.lib.mk   =-=-=-=-=
1144
1145The include file <bsd.lib.mk> has support for building libraries.  It has
1146the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1147includes, install, lint, and tags.  Additionally, it has a checkver target
1148which checks for installed shared object libraries whose version is greater
1149that the version of the source. It has a limited number of suffixes,
1150consistent with the current needs of the BSD tree.  <bsd.lib.mk> includes
1151<bsd.shlib.mk> to get shared library parameters.
1152
1153It sets/uses the following variables:
1154
1155LIB		The name of the library to build.
1156
1157LIBDIR		Target directory for libraries.
1158
1159MKARZERO	Normally, ar(1) sets the timestamps, uid, gid and
1160		permissions in files inside its archives to those of
1161		the file it was fed. This leads to non-reproduceable
1162		builds. If MKARZERO is set to "yes" (default is the
1163		same as MKREPRO, or "no" if MKREPRO is not defined),
1164		then the "D" flag is passed to ar, causing the
1165		timestamp, uid and gid to be zeroed and the file
1166		permissions to be set to 644. This allows .a files
1167		from different builds to be bit identical.
1168
1169SHLIBINSTALLDIR	Target directory for shared libraries if ${USE_SHLIBDIR}
1170		is not "no".
1171
1172SHLIB_MAJOR
1173SHLIB_MINOR
1174SHLIB_TEENY	Major, minor, and teeny version numbers of shared library
1175
1176USE_SHLIBDIR	If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
1177		as the path to install shared libraries to.
1178		USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
1179		Default: no
1180
1181LIBISMODULE	If not "no", install as ${LIB}.so (without the "lib" prefix),
1182		and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
1183		MKPROFILE=no MKSTATICLIB=no".
1184		Default: no
1185
1186LIBISPRIVATE	If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
1187		MKPROFILE=no", and don't install the (.a) library.
1188		This is useful for "build only" helper libraries.
1189		Default: no
1190
1191LIBISCXX	If not "no", Use ${CXX} instead of ${CC} to link
1192		shared libraries.
1193		This is useful for C++ libraries.
1194		Default: no
1195
1196LINTLIBDIR	Target directory for lint libraries.
1197
1198LIBGRP		Library group.
1199
1200LIBOWN		Library owner.
1201
1202LIBMODE		Library mode.
1203
1204LDADD		Additional loader objects.
1205
1206MAN		The manual pages to be installed (use a .1 - .9 suffix).
1207
1208NOCHECKVER_<library>
1209NOCHECKVER	If set, disables checking for installed shared object
1210		libraries with versions greater than the source.  A
1211		particular library name, without the "lib" prefix, may
1212		be appended to the variable name to disable the check for
1213		only that library.
1214
1215SRCS		List of source files to build the library.  Suffix types
1216		.s, .c, and .f are supported.  Note, .s files are preferred
1217		to .c files of the same name.  (This is not the default for
1218		versions of make.)
1219
1220LIBDPLIBS	A list of the tuples:
1221			libname  path-to-srcdir-of-libname
1222
1223		For each tuple;
1224		     *	LIBDO.libname contains the .OBJDIR of the library
1225			`libname', and if it is not set it is determined
1226			from the srcdir and added to MAKEOVERRIDES (the
1227			latter is to allow for build time optimization).
1228		     *	LDADD gets  -L${LIBDO.libname} -llibname    added.
1229		     *	DPADD gets  ${LIBDO.libname}/liblibname.so  or
1230				    ${LIBDO.libname}/liblibname.a   added.
1231
1232		The special value "_external" for LIBDO.lib makes the
1233		build system to assume the library comes from outside
1234		of the NetBSD source tree and only causes -llibname
1235		to be added to LDADD.
1236
1237		This variable may be used for individual libraries, as
1238		well as in parent directories to cache common libraries
1239		as a build-time optimization.
1240
1241The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1242if it exists, as well as the include file <bsd.man.mk>.
1243
1244It has rules for building profiled objects; profiled libraries are
1245built by default.
1246
1247Libraries are ranlib'd when made.
1248
1249
1250=-=-=-=-=   bsd.links.mk   =-=-=-=-=
1251
1252The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1253and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1254
1255LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1256is used. The defaults may be modified by other bsd.*.mk files which
1257include bsd.links.mk.  In the future, these variables may be replaced
1258by a method for explicitly recording hard links in a metadata log.
1259
1260LINKS		The list of hard links, consisting of pairs of paths:
1261			source-file target-file
1262		${DESTDIR} is prepended to both paths before linking.
1263		For example, to link /bin/test and /bin/[, use:
1264			LINKS=/bin/test /bin/[
1265
1266CONFIGLINKS	Similar semantics to LINKS, except that the links
1267		are installed by the `configinstall' target,
1268		not the `install' target.
1269
1270SYMLINKS	The list of symbolic links, consisting of pairs of paths:
1271			source-file target-file
1272		${DESTDIR} is only prepended to target-file before linking.
1273		For example, to symlink /usr/bin/tar to /bin/tar resulting
1274		in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1275			SYMLINKS=/bin/tar /usr/bin/tar
1276
1277CONFIGSYMLINKS	Similar semantics to SYMLINKS, except that the symbolic links
1278		are installed by the `configinstall' target,
1279		not the `install' target.
1280
1281LINKSOWN	Link owner.  [${BINOWN}]
1282
1283LINKSGRP	Link group.  [${BINGRP}]
1284
1285LINKSMODE	Link mode.  [${NONBINMODE}]
1286
1287LINKSOWN_<fn>	Link owner of the specific file <fn>.
1288
1289LINKSGRP_<fn>	Link group of the specific file <fn>.
1290
1291LINKSMODE_<fn>	Link mode of the specific file <fn>.
1292
1293
1294=-=-=-=-=   bsd.man.mk   =-=-=-=-=
1295
1296The include file <bsd.man.mk> handles installing manual pages and their
1297links.
1298
1299It has a three targets:
1300
1301	catinstall:
1302		Install the preformatted manual pages and their links.
1303	htmlinstall:
1304		Install the HTML manual pages and their links.
1305	maninstall:
1306		Install the manual page sources and their links.
1307
1308It sets/uses the following variables:
1309
1310MANDIR		Base path for manual installation.
1311
1312MANGRP		Manual group.
1313
1314MANOWN		Manual owner.
1315
1316MANMODE		Manual mode.
1317
1318MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
1319		or "/tahoe" for machine specific manual pages.
1320
1321MAN		The manual pages to be installed (use a .1 - .9 suffix).
1322
1323MLINKS		List of manual page links (using a .1 - .9 suffix).  The
1324		linked-to file must come first, the linked file second,
1325		and there may be multiple pairs.
1326
1327The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1328it exists.
1329
1330
1331=-=-=-=-=   bsd.obj.mk   =-=-=-=-=
1332
1333The include file <bsd.obj.mk> defines targets related to the creation
1334and use of separated object and source directories.
1335
1336If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1337${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1338it exists.  Otherwise make(1) looks for the existence of a
1339subdirectory (or a symlink to a directory) of the source directory
1340into which built targets should be placed.  If an environment variable
1341named MAKEOBJDIR is set, make(1) uses its value as the name of the
1342object directory; failing that, make first looks for a subdirectory
1343named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1344
1345Object directories are not created automatically by make(1) if they
1346don't exist; you need to run a separate "make obj".  (This will happen
1347during a top-level build if "MKOBJDIRS" is set to a value other than
1348"no").  When the source directory is a subdirectory of ${BSDSRCDIR} --
1349and this is determined by a simple string prefix comparison -- object
1350directories are created in a separate object directory tree, and a
1351symlink to the object directory in that tree is created in the source
1352directory; otherwise, "make obj" assumes that you're not in the main
1353source tree and that it's not safe to use a separate object tree.
1354
1355Several variables used by <bsd.obj.mk> control exactly what
1356directories and links get created during a "make obj":
1357
1358MAKEOBJDIR	If set, this is the component name of the object
1359		directory.
1360
1361OBJMACHINE	If this is set but MAKEOBJDIR is not set, creates
1362		object directories or links named "obj.${MACHINE}";
1363		otherwise, just creates ones named "obj".
1364
1365USR_OBJMACHINE  If set, and the current directory is a subdirectory of
1366		${BSDSRCDIR}, create object directory in the
1367		corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1368		otherwise, create it in the corresponding subdirectory
1369		of ${BSDOBJDIR}
1370
1371BUILDID		If set, the contents of this variable are appended
1372		to the object directory name.  If OBJMACHINE is also
1373		set, ".${BUILDID}" is added after ".${MACHINE}".
1374
1375
1376=-=-=-=-=   bsd.prog.mk   =-=-=-=-=
1377
1378The include file <bsd.prog.mk> handles building programs from one or
1379more source files, along with their manual pages.  It has a limited number
1380of suffixes, consistent with the current needs of the BSD tree.
1381<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1382
1383It has eight targets:
1384
1385	all:
1386		build the program and its manual page.  This also
1387		creates a GDB initialization file (.gdbinit) in
1388		the objdir.  The .gdbinit file sets the shared library
1389		prefix to ${DESTDIR} to facilitate cross-debugging.
1390	clean:
1391		remove the program, any object files and the files a.out,
1392		Errs, errs, mklog, and ${PROG}.core.
1393	cleandir:
1394		remove all of the files removed by the target clean, as
1395		well as .depend, tags, and any manual pages.
1396		`distclean' is a synonym for `cleandir'.
1397	depend:
1398		make the dependencies for the source files, and store
1399		them in the file .depend.
1400	includes:
1401		install any header files.
1402	install:
1403		install the program and its manual pages; if the Makefile
1404		does not itself define the target install, the targets
1405		beforeinstall and afterinstall may also be used to cause
1406		actions immediately before and after the install target
1407		is executed.
1408	lint:
1409		run lint on the source files
1410	tags:
1411		create a tags file for the source files.
1412
1413It sets/uses the following variables:
1414
1415BINGRP		Binary group.
1416
1417BINOWN		Binary owner.
1418
1419BINMODE		Binary mode.
1420
1421CLEANDIRFILES	Additional files to remove for the cleandir target.
1422
1423CLEANFILES	Additional files to remove for the clean and cleandir targets.
1424
1425COPTS		Additional flags to the compiler when creating C objects.
1426
1427COPTS.<fn>	Additional flags to the compiler when creating the
1428		C objects for <fn>.
1429		For <fn>.[ly], "<fn>.c" must be used.
1430
1431CPUFLAGS	Additional flags to the compiler/assembler to select
1432		CPU instruction set options, CPU tuning options, etc.
1433
1434CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1435		For <fn>.[ly], "<fn>.c" must be used.
1436
1437CPPFLAGS	Additional flags to the C pre-processor.
1438
1439CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1440		For <fn>.[ly], "<fn>.c" must be used.
1441
1442GDBINIT		List of GDB initialization files to add to "source"
1443		directives in the .gdbinit file that is created in the
1444		objdir.
1445
1446LDADD		Additional loader objects.  Usually used for libraries.
1447		For example, to load with the compatibility and utility
1448		libraries, use:
1449
1450			LDADD+=-lutil -lcompat
1451
1452LDFLAGS		Additional linker flags (passed to ${CC} during link).
1453
1454LINKS		See <bsd.links.mk>
1455
1456OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1457
1458OBJCOPTS.<fn>	Additional flags to the compiler when creating the
1459		ObjC objects for <fn>.
1460		For <fn>.[ly], "<fn>.c" must be used.
1461
1462SYMLINKS	See <bsd.links.mk>
1463
1464MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1465		defined, "MAN=${PROG}.1" is assumed.
1466
1467PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1468		time, with the value of this variable as args to paxctl(1).
1469
1470PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1471
1472PROG		The name of the program to build.  If not supplied, nothing
1473		is built.
1474
1475PROG_CXX	If defined, the name of the program to build.  Also
1476		causes <bsd.prog.mk> to link the program with the C++
1477		compiler rather than the C compiler.  PROG_CXX overrides
1478		the value of PROG if PROG is also set.
1479
1480PROGNAME	The name that the above program will be installed as, if
1481		different from ${PROG}.
1482
1483SRCS		List of source files to build the program.  If SRCS is not
1484		defined, it's assumed to be ${PROG}.c.
1485
1486DPSRCS		List of source files which are needed for generating
1487		dependencies, but are not needed in ${SRCS}.
1488
1489DPADD		Additional dependencies for the program.  Usually used for
1490		libraries.  For example, to depend on the compatibility and
1491		utility libraries use:
1492
1493			DPADD+=${LIBCOMPAT} ${LIBUTIL}
1494

1646
1647SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1648		strings, using xstr(1). Note that this will not work with
1649		parallel makes.
1650
1651STRIPFLAG	The flag passed to the install program to cause the binary
1652		to be stripped.
1653
1654SUBDIR		A list of subdirectories that should be built as well.
1655		Each of the targets will execute the same target in the
1656		subdirectories.
1657
1658SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1659		These are installed exactly like programs.
1660
1661SCRIPTSDIR	The location to install the scripts.  Each script can be
1662		installed to a separate path by setting SCRIPTSDIR_<script>.
1663
1664SCRIPTSNAME	The name that the above program will be installed as, if
1665		different from ${SCRIPTS}. These can be further specialized
1666		by setting SCRIPTSNAME_<script>.
1667
1668FILES		See description of <bsd.files.mk>.
1669
1670SHLINKDIR	Target directory for shared linker.  See description of
1671		<bsd.own.mk> for additional information about this variable.
1672
1673The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1674if it exists, as well as the include file <bsd.man.mk>.
1675
1676Some simple examples:
1677
1678To build foo from foo.c with a manual page foo.1, use:
1679
1680	PROG=	foo
1681
1682	.include <bsd.prog.mk>
1683
1684To build foo from foo.c with a manual page foo.2, add the line:
1685
1686	MAN=	foo.2
1687
1688If foo does not have a manual page at all, add the line:
1689
1690	MKMAN=	no
1691
1692If foo has multiple source files, add the line:
1693
1694	SRCS=	a.c b.c c.c d.c
1695
1696
1697=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1698
1699The include file <bsd.rpc.mk> contains a makefile fragment used to
1700construct source files built by rpcgen.
1701
1702The following macros may be defined in makefiles which include
1703<bsd.rpc.mk> in order to control which files get built and how they
1704are to be built:
1705
1706RPC_INCS:	construct .h file from .x file
1707RPC_XDRFILES:	construct _xdr.c from .x file
1708		(for marshalling/unmarshalling data types)
1709RPC_SVCFILES:	construct _svc.c from .x file
1710		(server-side stubs)
1711RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1712
1713RPC_XDIR:	Directory containing .x/.h files
1714
1715
1716=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1717
1718The include file <bsd.shlib.mk> computes parameters for shared library
1719installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1720included before <bsd.shlib.mk>.
1721
1722<bsd.own.mk> sets the following variables, if they are not already defined
1723(defaults are in brackets):
1724
1725SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1726		instead of ${LIBDIR} as the base path for shared library
1727		installation.  [/lib]
1728
1729SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1730		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1731		for all others.]
1732
1733_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1734		otherwise set to ${LIBDIR}
1735
1736SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1737
1738SHLINKDIR	Path to use for shared linker when building a program.
1739		[/libexec for programs in /bin and /sbin, /usr/libexec for
1740		all others.]
1741
1742
1743=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1744
1745The include file <bsd.subdir.mk> contains the default targets for building
1746subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1747clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1748following variables:
1749
1750NOSUBDIR	If this variable is defined, then the SUBDIR variable
1751		will be ignored and subdirectories will not be processed.
1752
1753SUBDIR		For all of the directories listed in ${SUBDIR}, the
1754		specified directory will be visited and the target made.
1755
1756		As a special case, the use of a token .WAIT as an
1757		entry in SUBDIR acts as a synchronization barrier
1758		when multiple make jobs are run; subdirs before the
1759		.WAIT must complete before any subdirs after .WAIT are
1760		started.  See make(1) for some caveats on use of .WAIT
1761		and other special sources.
1762
1763
1764=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1765
1766The include file <bsd.x11.mk> contains parameters and targets for
1767cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}.
1768It should be included after the general Makefile contents but before
1769the include files such as <bsd.prog.mk> and <bsd.lib.mk>.
1770
1771It provides the following targets:
1772	.man.1 .man.3 .man.4 .man.5 .man.7:
1773		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1774		these rules convert from X11's manual page source
1775		into an mdoc.old source file.
1776
1777It sets the following variables:
1778
1779BINDIR			Set to ${X11BINDIR}.
1780			To override, define after including <bsd.x11.mk>
1781
1782LIBDIR			Set to ${X11USRLIBDIR}.
1783			To override, define after including <bsd.x11.mk>
1784
1785MANDIR			Set to ${X11MANDIR}.
1786			To override, define after including <bsd.x11.mk>
1787

1789			${DESTDIR}${X11INCDIR}
1790
1791LDFLAGS			Appended with definitions to link from
1792			${DESTDIR}${X11USRLIBDIR}

1807
1808X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1809
1810X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1811
1812X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1813
1814It uses the following variables:
1815
1816APPDEFS			List of app-default files to install.
1817
1818CPPSCRIPTS		List of files/scripts to run through cpp(1)
1819			and then ${X11TOOL_UNXCOMM}.  The source files

1827=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1828
1829The following files are described here for completion, but they are not
1830supposed to be included directly from other Makefiles; they are used
1831internally by other system files.
1832
1833=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1834
1835The include file <bsd.sys.mk> is used by other system mk files and
