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
208MKGROFFHTMLDOC	If "no", avoid trying to use groff to generate html for

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

435		non-root "make install".
436		Default: no
437
438MKUPDATE 	If not "no", 'make install' only installs targets that are
439		more recently modified in the source directories that their
440		installed counterparts.
441		Default: no
442

444		src/external/mit/xorg to cross-build X11 and automatically
445		enables creation of X sets.
446		Default: no
447
448MKX11FONTS	If not "no", do not build or install the X fonts.  The xfont
449		set is still created but will be empty.
450		Default: yes
451
452MKX11MOTIF:	If "yes", build the native X11 libGLw with Motif stubs.  If
453		Motif is not installed in the default location /usr/pkg, the
454		location can be specified using the X11MOTIFPATH variable.

468		libraries, and programs.
469		Default: yes
470
471USE_HESIOD	If "no", disables building Hesiod support into
472		various system utilities/libraries that support it.
473		If ${MKHESIOD} is "no", USE_HESIOD will also be
474		forced to "no".

480
481USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
482		designed for improved performance with threaded

503		Default: no
504
505USE_SSP		If "no", disables GCC stack protection code, which
506		detects stack overflows and aborts the program. The
507		stack protection code imposes a performance penalty
508		of about 5%.
509		Default: "no", unless "USE_FORT" is set to "yes"
510
511NOSSP		Don't compile with stack protector during build.
512		It is set internally for standalone programs.
513
514USE_FORT 	If "yes" turns on substitute wrappers for commonly used
515		functions that do not do bounds checking regularly, but
516		they could in some cases by using the gcc
517		__builtin_object_size() function to determine the buffer
518		size where it is known and detect buffer overflows.
519		These substitute functions are in /usr/include/ssp.
520		Default: depends on the part of the source tree
521
522NOFORT		Don't compile with substitute wrappers during build.

543CXXFLAGS.<prog>	These provide a way to specify additions to the associated
544		variables in a way that applies only to a particular library
545		or program.  <lib> corresponds to the LIB variable set in
546		the library's makefile.  <prog> corresponds to either PROG
547		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
548		set to "-g", "-g" will be added to COPTS only when compiling
549		the crypto library.
550
551The active compiler is selected using the following variables:
552AVAILABLE_COMPILER
553		List of available compiler suites.  Processed in order
554		for selecting the active compiler for each frontend.
555HAVE_PCC	If defined, PCC is present and enabled.
556HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
557UNSUPPORTED_COMPILER.xxx
558		If defined, the support for compiler "xxx" is disabled.
559
560For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
561ACTIVE_CC	Active compile suite for the CC frontend.
562SUPPORTED_CC	Compile suite with support for the CC frontend.
563TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
564
565=-=-=-=-=   sys.mk   =-=-=-=-=
566
567The include file <sys.mk> has the default rules for all makes, in the BSD
568environment or otherwise.  You probably don't want to touch this file.
569
570=-=-=-=-=   bsd.own.mk   =-=-=-=-=
571
572The include file <bsd.own.mk> contains source tree configuration parameters,
573such as the owners, groups, etc. for both manual pages and binaries, and
574a few global "feature configuration" parameters.
575
576It has no targets.
577
578To get system-specific configuration parameters, <bsd.own.mk> will try to
579include the file specified by the "MAKECONF" variable.  If MAKECONF is not
580set, or no such file exists, the system make configuration file, /etc/mk.conf
581is included.  These files may define any of the variables described below.
582
583<bsd.own.mk> sets the following variables, if they are not already defined
584(defaults are in brackets):
585
586NETBSDSRCDIR	Top of the NetBSD source tree.
587		If _SRC_TOP_ != "", that will be used as the default,
588		otherwise BSDSRCDIR will be used as the default.
589		Various makefiles within the NetBSD source tree will
590		use this to reference the top level of the source tree.
591
592_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
593		based on the presence of tools/ and build.sh.  This variable
594		is "internal" to <bsd.own.mk>, although its value is only
595		determined once and then propagated to all sub-makes.
596
597_NETBSD_VERSION_DEPENDS
598		A list of files which contain information about
599		the version of the NetBSD being built.  This is
600		defined only if the current directory appears
601		to be inside a NetBSD source tree.  The list of
602		files includes ${NETBSDSRCDIR}/sys/sys/param.h
603		(which contains the kernel version number),
604		${NETBSDSRCDIR}/sys/conf/newvers.sh and
605		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
606		interpret the information in sys/sys/param.h), and
607		${_SRC_TOP_OBJ_}/params (which is an optional file,
608		created by "make build" in ${_SRC_TOP_}/Makefile,
609		containing all the variables that may influence the
610		build).
611
612		Targets that depend on the NetBSD version, or on
613		variables defined at build time, can declare a
614		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
615
616			version.c: ${_NETBSD_VERSION_DEPENDS}
617				commands to create version.c
618
619BSDSRCDIR	The real path to the system sources, so that 'make obj'
620		will work correctly.  [/usr/src]

702
703X11USRLIBDIR	X11 library directory.  [${X11ROOTDIR}/lib]
704
705STRIPFLAG	The flag passed to the install program to cause the binary
706		to be stripped.  This is to be used when building your
707		own install script so that the entire system can be made
708		stripped/not-stripped using a single knob.  []
709
710COPY		The flag passed to the install program to cause the binary
711		to be copied rather than moved.  This is to be used when
712		building our own install script so that the entire system
713		can either be installed with copies, or with moves using
714		a single knob.  [-c]
715
716MAKEDIRTARGETENV
717		Environment variables passed to the child make process
718		invoked by MAKEDIRTARGET.
719
720MAKEDIRTARGET dir target [params]
721		Runs "cd $${dir} && ${MAKE} [params] $${target}",
722		displaying a "pretty" message whilst doing so.
723
724RELEASEMACHINEDIR
725		Subdirectory used below RELEASEDIR when building
726		a release.  [${MACHINE}]
727
728RELEASEMACHINE	Subdirectory or path component used for the following
729		paths:
730			distrib/${RELEASEMACHINE}
731			distrib/notes/${RELEASEMACHINE}
732			etc/etc.${RELEASEMACHINE}
733		Used when building a release.  [${MACHINE}]
734
735Additionally, the following variables may be set by <bsd.own.mk> or in a
736make configuration file to modify the behavior of the system build
737process (default values are in brackets along with comments, if set by
738<bsd.own.mk>):
739
740USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
741		be used as part of a build in progress.
742		Supported values:
743
744		yes	Use the tools from TOOLDIR.
745			Must be set to this if cross-compiling.
746
747		no	Do not use the tools from TOOLDIR, but refuse to
748			build native compilation tool components that are
749			version-specific for that tool.
750
751		never	Do not use the tools from TOOLDIR, even when
752			building native tool components.  This is similar to
753			the traditional NetBSD build method, but does not
754			verify that the compilation tools in use are
755			up-to-date enough in order to build the tree
756			successfully.  This may cause build or runtime
757			problems when building the whole NetBSD source tree.
758
759		Default: "yes" if building all or part of a whole NetBSD
760		source tree (detected automatically); "no" otherwise
761		(to preserve traditional semantics of the <bsd.*.mk>
762		make(1) include files).
763
764OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
765		use ELF -- currently all architectures].
766
767TOOLCHAIN_MISSING
768		If not "no", this indicates that the platform being built
769		does not have a working in-tree toolchain.  If the
770		${MACHINE_ARCH} in question falls into this category,
771		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
772		Otherwise, the variable is unconditionally assigned the
773		value "no".
774		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
775		unconditionally assigned the value "no".
776
777EXTERNAL_TOOLCHAIN
778		This variable is not directly set by <bsd.own.mk>, but
779		including <bsd.own.mk> is the canonical way to gain
780		access to this variable.  The variable should be defined
781		either in the user's environment or in the user's mk.conf
782		file.  If defined, this variable indicates the root of
783		an external toolchain which will be used to build the
784		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
785		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
786		cross-compile framework.
787
788		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
789		assigned the value "no", since the external version of the
790		compiler may not be able to build the library components of
791		the in-tree compiler.
792
793		This variable should be used in conjunction with an appropiate
794		HAVE_GCC or HAVE_LLVM setting to control the compiler flags.
795
796		NOTE: This variable is not yet used in as many places as
797		it should be.  Expect the exact semantics of this variable
798		to change in the short term as parts of the cross-compile
799		framework continue to be cleaned up.
800
801The following variables are defined to commands to perform the
802appropriate operation, with the default in [brackets].  Note that
803the defaults change if USETOOLS == "yes":
804
805TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

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

1488		C objects for <fn>.
1489		For <fn>.[ly], "<fn>.c" must be used.
1490
1491CPUFLAGS	Additional flags to the compiler/assembler to select
1492		CPU instruction set options, CPU tuning options, etc.
1493
1494CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1495		For <fn>.[ly], "<fn>.c" must be used.
1496
1497CPPFLAGS	Additional flags to the C pre-processor.
1498
1499CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1500		For <fn>.[ly], "<fn>.c" must be used.
1501
1502GDBINIT		List of GDB initialization files to add to "source"
1503		directives in the .gdbinit file that is created in the
1504		objdir.
1505
1506LDADD		Additional loader objects.  Usually used for libraries.
1507		For example, to load with the compatibility and utility
1508		libraries, use:
1509
1510			LDADD+=-lutil -lcompat
1511
1512LDFLAGS		Additional linker flags (passed to ${CC} during link).
1513
1514LINKS		See <bsd.links.mk>
1515
1516OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1517
1518OBJCOPTS.<fn>	Additional flags to the compiler when creating the
1519		ObjC objects for <fn>.
1520		For <fn>.[ly], "<fn>.c" must be used.
1521
1522SYMLINKS	See <bsd.links.mk>
1523
1524MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1525		defined, "MAN=${PROG}.1" is assumed.
1526
1527PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1528		time, with the value of this variable as args to paxctl(1).
1529
1530PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1531
1532PROG		The name of the program to build.  If not supplied, nothing
1533		is built.
1534
1535PROG_CXX	If defined, the name of the program to build.  Also
1536		causes <bsd.prog.mk> to link the program with the C++
1537		compiler rather than the C compiler.  PROG_CXX overrides
1538		the value of PROG if PROG is also set.
1539
1540PROGNAME	The name that the above program will be installed as, if
1541		different from ${PROG}.
1542
1543SRCS		List of source files to build the program.  If SRCS is not
1544		defined, it's assumed to be ${PROG}.c.
1545
1546DPSRCS		List of source files which are needed for generating
1547		dependencies, but are not needed in ${SRCS}.
1548
1549DPADD		Additional dependencies for the program.  Usually used for
1550		libraries.  For example, to depend on the compatibility and
1551		utility libraries use:
1552
1553			DPADD+=${LIBCOMPAT} ${LIBUTIL}
1554
1555		The following system libraries are predefined for DPADD:

1706
1707SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1708		strings, using xstr(1). Note that this will not work with
1709		parallel makes.
1710
1711STRIPFLAG	The flag passed to the install program to cause the binary
1712		to be stripped.
1713
1714SUBDIR		A list of subdirectories that should be built as well.
1715		Each of the targets will execute the same target in the
1716		subdirectories.
1717
1718SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1719		These are installed exactly like programs.
1720
1721SCRIPTSDIR	The location to install the scripts.  Each script can be
1722		installed to a separate path by setting SCRIPTSDIR_<script>.
1723
1724SCRIPTSNAME	The name that the above program will be installed as, if
1725		different from ${SCRIPTS}. These can be further specialized
1726		by setting SCRIPTSNAME_<script>.
1727
1728FILES		See description of <bsd.files.mk>.
1729
1730SHLINKDIR	Target directory for shared linker.  See description of
1731		<bsd.own.mk> for additional information about this variable.
1732
1733The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1734if it exists, as well as the include file <bsd.man.mk>.
1735
1736Some simple examples:
1737
1738To build foo from foo.c with a manual page foo.1, use:
1739
1740	PROG=	foo
1741
1742	.include <bsd.prog.mk>
1743
1744To build foo from foo.c with a manual page foo.2, add the line:
1745
1746	MAN=	foo.2
1747
1748If foo does not have a manual page at all, add the line:
1749
1750	MKMAN=	no
1751
1752If foo has multiple source files, add the line:
1753
1754	SRCS=	a.c b.c c.c d.c
1755
1756
1757=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1758
1759The include file <bsd.rpc.mk> contains a makefile fragment used to
1760construct source files built by rpcgen.
1761
1762The following macros may be defined in makefiles which include
1763<bsd.rpc.mk> in order to control which files get built and how they
1764are to be built:
1765
1766RPC_INCS:	construct .h file from .x file
1767RPC_XDRFILES:	construct _xdr.c from .x file
1768		(for marshalling/unmarshalling data types)
1769RPC_SVCFILES:	construct _svc.c from .x file
1770		(server-side stubs)
1771RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1772
1773RPC_XDIR:	Directory containing .x/.h files
1774
1775
1776=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1777
1778The include file <bsd.shlib.mk> computes parameters for shared library
1779installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1780included before <bsd.shlib.mk>.
1781
1782<bsd.own.mk> sets the following variables, if they are not already defined
1783(defaults are in brackets):
1784
1785SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1786		instead of ${LIBDIR} as the base path for shared library
1787		installation.  [/lib]
1788
1789SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1790		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1791		for all others.]
1792
1793_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1794		otherwise set to ${LIBDIR}
1795
1796SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1797
1798SHLINKDIR	Path to use for shared linker when building a program.
1799		[/libexec for programs in /bin and /sbin, /usr/libexec for
1800		all others.]
1801
1802
1803=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1804
1805The include file <bsd.subdir.mk> contains the default targets for building
1806subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1807clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1808following variables:
1809
1810NOSUBDIR	If this variable is defined, then the SUBDIR variable
1811		will be ignored and subdirectories will not be processed.
1812
1813SUBDIR		For all of the directories listed in ${SUBDIR}, the
1814		specified directory will be visited and the target made.
1815
1816		As a special case, the use of a token .WAIT as an
1817		entry in SUBDIR acts as a synchronization barrier
1818		when multiple make jobs are run; subdirs before the
1819		.WAIT must complete before any subdirs after .WAIT are
1820		started.  See make(1) for some caveats on use of .WAIT
1821		and other special sources.
1822
1823
1824=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1825
1826The include file <bsd.x11.mk> contains parameters and targets for
1827cross-building X11 from ${X11SRCDIR.<package>}.  It should be included
1828after the general Makefile contents but before the include files such as
1829<bsd.prog.mk> and <bsd.lib.mk>.
1830
1831It provides the following targets:
1832	.man.1 .man.3 .man.4 .man.5 .man.7:
1833		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1834		these rules convert from X11's manual page source
1835		into an mdoc.old source file.
1836
1837It sets the following variables:
1838
1839BINDIR			Set to ${X11BINDIR}.
1840			To override, define after including <bsd.x11.mk>
1841
1842LIBDIR			Set to ${X11USRLIBDIR}.
1843			To override, define after including <bsd.x11.mk>
1844
1845MANDIR			Set to ${X11MANDIR}.
1846			To override, define after including <bsd.x11.mk>
1847
1848CPPFLAGS		Appended with definitions to include from
1849			${DESTDIR}${X11INCDIR}
1850
1851LDFLAGS			Appended with definitions to link from
1852			${DESTDIR}${X11USRLIBDIR}
1853
1854X11FLAGS.CONNECTION	Equivalent to X11's CONNECTION_FLAGS.
1855
1856X11FLAGS.EXTENSION	Equivalent to X11's EXT_DEFINES.
1857
1858X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1859
1860X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1861
1862X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1863
1864X11FLAGS.THREADLIB	Equivalent to X11's THREADS_DEFINES for libraries.
1865
1866X11FLAGS.THREADS	Equivalent to X11's THREADS_DEFINES.
1867
1868X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1869
1870X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1871
1872X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1873
1874It uses the following variables:
1875
1876APPDEFS			List of app-default files to install.
1877
1878CPPSCRIPTS		List of files/scripts to run through cpp(1)
1879			and then ${X11TOOL_UNXCOMM}.  The source files
1880			have a `.cpp' suffix, the generated files do not.
1881
1882CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1883
1884CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.

1887=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1888
1889The following files are described here for completion, but they are not
1890supposed to be included directly from other Makefiles; they are used
1891internally by other system files.
1892
1893=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1894
1895The include file <bsd.sys.mk> is used by other system mk files and
1896it is not intended to be included standalone. It contains rules and
1897system build variables. It requires bsd.own.mk to be included first.
1898It contains overrides that are used when building the NetBSD source tree.
1899
