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

486
487USE_FORT 	If "yes" turns on substitute wrappers for commonly used
488		functions that do not do bounds checking regularly, but
489		they could in some cases by using the gcc
490		__builtin_object_size() function to determine the buffer
491		size where it is known and detect buffer overflows.
492		These substitute functions are in /usr/include/ssp.
493		Default: depends on the part of the source tree
494
495USE_YP		If "no", disables building YP (NIS) support into

505OBJCOPTS.lib<lib>
506LDADD.lib<lib>
507CPPFLAGS.lib<lib>
508CXXFLAGS.lib<lib>
509COPTS.<prog>
510OBJCCOPTS.<prog>
511LDADD.<prog>
512CPPFLAGS.<prog>
513CXXFLAGS.<prog>	These provide a way to specify additions to the associated
514		variables in a way that applies only to a particular library
515		or program.  <lib> corresponds to the LIB variable set in
516		the library's makefile.  <prog> corresponds to either PROG
517		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
518		set to "-g", "-g" will be added to COPTS only when compiling
519		the crypto library.
520
521The active compiler is selected using the following variables:
522AVAILABLE_COMPILER
523		List of available compiler suites.  Processed in order
524		for selecting the active compiler for each frontend.

535=-=-=-=-=   sys.mk   =-=-=-=-=
536
537The include file <sys.mk> has the default rules for all makes, in the BSD
538environment or otherwise.  You probably don't want to touch this file.
539

541
542The include file <bsd.own.mk> contains source tree configuration parameters,
543such as the owners, groups, etc. for both manual pages and binaries, and
544a few global "feature configuration" parameters.
545
546It has no targets.
547
548To get system-specific configuration parameters, <bsd.own.mk> will try to
549include the file specified by the "MAKECONF" variable.  If MAKECONF is not
550set, or no such file exists, the system make configuration file, /etc/mk.conf
551is included.  These files may define any of the variables described below.
552
553<bsd.own.mk> sets the following variables, if they are not already defined
554(defaults are in brackets):
555
556NETBSDSRCDIR	Top of the NetBSD source tree.
557		If _SRC_TOP_ != "", that will be used as the default,
558		otherwise BSDSRCDIR will be used as the default.
559		Various makefiles within the NetBSD source tree will
560		use this to reference the top level of the source tree.
561
562_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
563		based on the presence of tools/ and build.sh.  This variable
564		is "internal" to <bsd.own.mk>, although its value is only
565		determined once and then propagated to all sub-makes.
566
567_NETBSD_VERSION_DEPENDS
568		A list of files which contain information about
569		the version of the NetBSD being built.  This is
570		defined only if the current directory appears
571		to be inside a NetBSD source tree.  The list of
572		files includes ${NETBSDSRCDIR}/sys/sys/param.h
573		(which contains the kernel version number),
574		${NETBSDSRCDIR}/sys/conf/newvers.sh and
575		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
576		interpret the information in sys/sys/param.h), and
577		${_SRC_TOP_OBJ_}/params (which is an optional file,
578		created by "make build" in ${_SRC_TOP_}/Makefile,
579		containing all the variables that may influence the
580		build).
581
582		Targets that depend on the NetBSD version, or on
583		variables defined at build time, can declare a
584		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
585
586			version.c: ${_NETBSD_VERSION_DEPENDS}
587				commands to create version.c
588
589BSDSRCDIR	The real path to the system sources, so that 'make obj'
590		will work correctly.  [/usr/src]

617		If not set, programs link according to their makefile.
618
619LIBDIR		Base path for library installation.  [/usr/lib]

673
674X11USRLIBDIR	X11 library directory.  [${X11ROOTDIR}/lib]
675
676STRIPFLAG	The flag passed to the install program to cause the binary
677		to be stripped.  This is to be used when building your
678		own install script so that the entire system can be made
679		stripped/not-stripped using a single knob.  []
680
681COPY		The flag passed to the install program to cause the binary
682		to be copied rather than moved.  This is to be used when
683		building our own install script so that the entire system
684		can either be installed with copies, or with moves using
685		a single knob.  [-c]
686
687MAKEDIRTARGETENV
688		Environment variables passed to the child make process
689		invoked by MAKEDIRTARGET.
690
691MAKEDIRTARGET dir target [params]
692		Runs "cd $${dir} && ${MAKE} [params] $${target}",
693		displaying a "pretty" message whilst doing so.
694
695RELEASEMACHINEDIR
696		Subdirectory used below RELEASEDIR when building
697		a release.  [${MACHINE}]
698
699RELEASEMACHINE	Subdirectory or path component used for the following
700		paths:
701			distrib/${RELEASEMACHINE}
702			distrib/notes/${RELEASEMACHINE}
703			etc/etc.${RELEASEMACHINE}
704		Used when building a release.  [${MACHINE}]
705
706Additionally, the following variables may be set by <bsd.own.mk> or in a
707make configuration file to modify the behavior of the system build
708process (default values are in brackets along with comments, if set by
709<bsd.own.mk>):
710
711USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
712		be used as part of a build in progress.
713		Supported values:
714
715		yes	Use the tools from TOOLDIR.
716			Must be set to this if cross-compiling.
717
718		no	Do not use the tools from TOOLDIR, but refuse to
719			build native compilation tool components that are
720			version-specific for that tool.
721
722		never	Do not use the tools from TOOLDIR, even when
723			building native tool components.  This is similar to
724			the traditional NetBSD build method, but does not
725			verify that the compilation tools in use are
726			up-to-date enough in order to build the tree
727			successfully.  This may cause build or runtime
728			problems when building the whole NetBSD source tree.
729
730		Default: "yes" if building all or part of a whole NetBSD
731		source tree (detected automatically); "no" otherwise
732		(to preserve traditional semantics of the <bsd.*.mk>
733		make(1) include files).
734
735OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
736		use ELF -- currently all architectures].
737
738TOOLCHAIN_MISSING
739		If not "no", this indicates that the platform being built
740		does not have a working in-tree toolchain.  If the
741		${MACHINE_ARCH} in question falls into this category,
742		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
743		Otherwise, the variable is unconditionally assigned the
744		value "no".
745		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
746		unconditionally assigned the value "no".
747
748EXTERNAL_TOOLCHAIN
749		This variable is not directly set by <bsd.own.mk>, but
750		including <bsd.own.mk> is the canonical way to gain
751		access to this variable.  The variable should be defined
752		either in the user's environment or in the user's mk.conf
753		file.  If defined, this variable indicates the root of
754		an external toolchain which will be used to build the
755		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
756		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
757		cross-compile framework.
758
759		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
760		assigned the value "no", since the external version of the
761		compiler may not be able to build the library components of
762		the in-tree compiler.
763
764		NOTE: This variable is not yet used in as many places as
765		it should be.  Expect the exact semantics of this variable
766		to change in the short term as parts of the cross-compile
767		framework continue to be cleaned up.
768
769The following variables are defined to commands to perform the
770appropriate operation, with the default in [brackets].  Note that
771the defaults change if USETOOLS == "yes":
772
773TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

923
924<bsd.own.mk> is generally useful when building your own Makefiles so that
925they use the same default owners etc. as the rest of the tree.
926
927
928=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
929
930The include file <bsd.clean.mk> defines the clean and cleandir
931targets.  It uses the following variables:
932
933CLEANFILES	Files to remove for both the clean and cleandir targets.
934
935CLEANDIRFILES	Files to remove for the cleandir target, but not for
936		the clean target.
937
938MKCLEANSRC	Controls whether or not the clean and cleandir targets
939		will delete files from both the object directory,
940		${.OBJDIR}, and the source directory, ${.CURDIR}.
941
942		If MKCLEANSRC is set to "no", then the file names in
943		CLEANFILES or CLEANDIRFILES are interpreted relative
944		to the object directory, ${.OBJDIR}.  This is the
945		traditional behaviour.
946
947		If MKCLEANSRC is set to "yes", then the file deletion
948		is performed relative to both the object directory,
949		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
950		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
951		Deleting files from ${.CURDIR} is intended to remove
952		stray output files that had been left in the source
953		directory by an earlier build that did not use object
954		directories.
955
956		The default is MKCLEANSRC=yes.  If you always build with
957		separate object directories, and you are sure that there
958		are no stray files in the source directories, then you
959		may set MKCLEANSRC=no to save some time.
960
961MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
962		will verify that files have been deleted.
963
964		If MKCLEANVERIFY is set to "no", then the files will
965		be deleted using a "rm -f" command, and its success or
966		failure will be ignored.
967
968		If MKCLEANVERIFY is set to "yes", then the success of
969		the "rm -f" command will be verified using an "ls"
970		command.
971
972		The default is MKCLEANVERIFY=yes.  If you are sure that
973		there will be no problems caused by file permissions,
974		read-only file systems, or the like, then you may set
975		MKCLEANVERIFY=no to save some time.
976
977To use the clean and cleandir targets defined in <bsd.clean.mk>, other
978Makefiles or bsd.*.mk files should append file names to the CLEANFILES
979or CLEANDIRFILES variables.  For example:
980
981	    CLEANFILES+= a.out
982	    CLEANDIRFILES+= .depend
983
984	    .include <bsd.clean.mk>
985
986The files listed in CLEANFILES and CLEANDIRFILES must not be
987directories, because the potential risk from running "rm -rf" commands
988in bsd.clean.mk is considered too great.  If you want to recursively
989delete a directory as part of "make clean" or "make cleandir" then you
990need to provide your own target.
991
992=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
993
994The include file <bsd.dep.mk> contains the default targets for building
995.depend files.  It creates .d files from entries in SRCS and DPSRCS
996that are C, C++, or Objective C source files, and builds .depend from the
997.d files.  All other files in SRCS and all of DPSRCS will be used as
998dependencies for the .d files.  In order for this to function correctly,
999it should be .included after all other .mk files and directives that may
1000modify SRCS or DPSRCS.  It uses the following variables:
1001
1002SRCS		List of source files to build the program.
1003
1004DPSRCS		List of source files which are needed for generating
1005		dependencies, but are not needed in ${SRCS}.
1006
1007
1008=-=-=-=-=   bsd.files.mk   =-=-=-=-=
1009
1010The include file <bsd.files.mk> handles the FILES variables and is included
1011from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1012
1013FILES		The list of files to install.
1014
1015CONFIGFILES	Similar semantics to FILES, except that the files
1016		are installed by the `configinstall' target,
1017		not the `install' target.
1018		The FILES* variables documented below also apply.
1019
1020FILESOWN	File owner.  [${BINOWN}]
1021
1022FILESGRP	File group.  [${BINGRP}]
1023
1024FILESMODE	File mode.  [${NONBINMODE}]
1025
1026FILESDIR	The location to install the files.
1027
1028FILESNAME	Optional name to install each file as.
1029
1030FILESOWN_<fn>	File owner of the specific file <fn>.
1031
1032FILESGRP_<fn>	File group of the specific file <fn>.
1033
1034FILESMODE_<fn>	File mode of the specific file <fn>.
1035
1036FILESDIR_<fn>	The location to install the specific file <fn>.
1037
1038FILESNAME_<fn>	Optional name to install <fn> as.
1039
1040FILESBUILD	If this variable is defined, then its value will be
1041		used as the default for all FILESBUILD_<fn> variables.
1042		Otherwise, the default will be "no".
1043
1044FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1045		targets to be built by `realall'.  Users of that variable
1046		should provide a target to build the file.
1047
1048
1049BUILDSYMLINKS	List of two word items:
1050			lnsrc lntgt
1051		For each lnsrc item, create a symlink named lntgt.
1052		The lntgt symlinks are removed by the cleandir target.
1053
1054UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1055		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1056		The source files have a `.uue' suffix, the generated files do
1057		not.
1058
1059UUDECODE_FILES_RENAME_<fn>
1060		Rename the output from the decode to the provided name.
1061		
1062		*NOTE: These files are simply decoded, with no install or other
1063		       rule applying implicitly except being added to the clean
1064		       target.

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

1519		utility libraries use:
1520
1521			DPADD+=${LIBCOMPAT} ${LIBUTIL}
1522

1676
1677SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1678		strings, using xstr(1). Note that this will not work with
1679		parallel makes.
1680
1681STRIPFLAG	The flag passed to the install program to cause the binary
1682		to be stripped.
1683
1684SUBDIR		A list of subdirectories that should be built as well.
1685		Each of the targets will execute the same target in the
1686		subdirectories.
1687
1688SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1689		These are installed exactly like programs.
1690
1691SCRIPTSDIR	The location to install the scripts.  Each script can be
1692		installed to a separate path by setting SCRIPTSDIR_<script>.
1693
1694SCRIPTSNAME	The name that the above program will be installed as, if
1695		different from ${SCRIPTS}. These can be further specialized
1696		by setting SCRIPTSNAME_<script>.
1697
1698FILES		See description of <bsd.files.mk>.
1699
1700SHLINKDIR	Target directory for shared linker.  See description of
1701		<bsd.own.mk> for additional information about this variable.
1702
1703The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1704if it exists, as well as the include file <bsd.man.mk>.
1705
1706Some simple examples:
1707
1708To build foo from foo.c with a manual page foo.1, use:
1709
1710	PROG=	foo
1711
1712	.include <bsd.prog.mk>
1713
1714To build foo from foo.c with a manual page foo.2, add the line:
1715
1716	MAN=	foo.2
1717
1718If foo does not have a manual page at all, add the line:
1719
1720	MKMAN=	no
1721
1722If foo has multiple source files, add the line:
1723
1724	SRCS=	a.c b.c c.c d.c
1725
1726
1727=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1728
1729The include file <bsd.rpc.mk> contains a makefile fragment used to
1730construct source files built by rpcgen.
1731
1732The following macros may be defined in makefiles which include
1733<bsd.rpc.mk> in order to control which files get built and how they
1734are to be built:
1735
1736RPC_INCS:	construct .h file from .x file
1737RPC_XDRFILES:	construct _xdr.c from .x file
1738		(for marshalling/unmarshalling data types)
1739RPC_SVCFILES:	construct _svc.c from .x file
1740		(server-side stubs)
1741RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1742
1743RPC_XDIR:	Directory containing .x/.h files
1744
1745
1746=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1747
1748The include file <bsd.shlib.mk> computes parameters for shared library
1749installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1750included before <bsd.shlib.mk>.
1751
1752<bsd.own.mk> sets the following variables, if they are not already defined
1753(defaults are in brackets):
1754
1755SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1756		instead of ${LIBDIR} as the base path for shared library
1757		installation.  [/lib]
1758
1759SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1760		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1761		for all others.]
1762
1763_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1764		otherwise set to ${LIBDIR}
1765
1766SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1767
1768SHLINKDIR	Path to use for shared linker when building a program.
1769		[/libexec for programs in /bin and /sbin, /usr/libexec for
1770		all others.]
1771
1772
1773=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1774
1775The include file <bsd.subdir.mk> contains the default targets for building
1776subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1777clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1778following variables:
1779
1780NOSUBDIR	If this variable is defined, then the SUBDIR variable
1781		will be ignored and subdirectories will not be processed.
1782
1783SUBDIR		For all of the directories listed in ${SUBDIR}, the
1784		specified directory will be visited and the target made.
1785
1786		As a special case, the use of a token .WAIT as an
1787		entry in SUBDIR acts as a synchronization barrier
1788		when multiple make jobs are run; subdirs before the
1789		.WAIT must complete before any subdirs after .WAIT are
1790		started.  See make(1) for some caveats on use of .WAIT
1791		and other special sources.
1792
1793
1794=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1795
1796The include file <bsd.x11.mk> contains parameters and targets for
1797cross-building X11 from ${X11SRCDIR.<package>}.  It should be included
1798after the general Makefile contents but before the include files such as
1799<bsd.prog.mk> and <bsd.lib.mk>.
1800
1801It provides the following targets:
1802	.man.1 .man.3 .man.4 .man.5 .man.7:
1803		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1804		these rules convert from X11's manual page source
1805		into an mdoc.old source file.
1806
1807It sets the following variables:
1808
1809BINDIR			Set to ${X11BINDIR}.
1810			To override, define after including <bsd.x11.mk>
1811
1812LIBDIR			Set to ${X11USRLIBDIR}.
1813			To override, define after including <bsd.x11.mk>
1814
1815MANDIR			Set to ${X11MANDIR}.
1816			To override, define after including <bsd.x11.mk>
1817
1818CPPFLAGS		Appended with definitions to include from
1819			${DESTDIR}${X11INCDIR}
1820
1821LDFLAGS			Appended with definitions to link from
1822			${DESTDIR}${X11USRLIBDIR}
1823

1825
1826X11FLAGS.EXTENSION	Equivalent to X11's EXT_DEFINES.
1827
1828X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1829
1830X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1831
1832X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1833
1834X11FLAGS.THREADLIB	Equivalent to X11's THREADS_DEFINES for libraries.
1835
1836X11FLAGS.THREADS	Equivalent to X11's THREADS_DEFINES.
1837
1838X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1839
1840X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1841
1842X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1843
1844It uses the following variables:
1845
1846APPDEFS			List of app-default files to install.
1847
1848CPPSCRIPTS		List of files/scripts to run through cpp(1)
1849			and then ${X11TOOL_UNXCOMM}.  The source files
1850			have a `.cpp' suffix, the generated files do not.
1851
1852CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1853
1854CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.
1855
1856
1857=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1858
1859The following files are described here for completion, but they are not
1860supposed to be included directly from other Makefiles; they are used
1861internally by other system files.
1862
1863=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1864
1865The include file <bsd.sys.mk> is used by other system mk files and
1866it is not intended to be included standalone. It contains rules and
