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

12
13RANDOM THINGS WORTH KNOWING:
14
15The files are simply C-style #include files, and pretty much behave like
16you'd expect.  The syntax is slightly different in that a single '.' is
17used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
18
19One difference that will save you lots of debugging time is that inclusion
20of the file is normally done at the *end* of the Makefile.  The reason for
21this is because .mk files often modify variables and behavior based on the
22values of variables set in the Makefile.  To make this work, remember that
23the FIRST target found is the target that is used, i.e. if the Makefile has:
24
25	a:
26		echo a
27	a:
28		echo a number two
29
30the command "make a" will echo "a".  To make things confusing, the SECOND
31variable assignment is the overriding one, i.e. if the Makefile has:
32
33	a=	foo
34	a=	bar
35
36	b:
37		echo ${a}
38
39the command "make b" will echo "bar".  This is for compatibility with the
40way the V7 make behaved.
41
42It's fairly difficult to make the BSD .mk files work when you're building
43multiple programs in a single directory.  It's a lot easier to split up the
44programs than to deal with the problem.  Most of the agony comes from making
45the "obj" directory stuff work right, not because we switched to a new version
46of make.  So, don't get mad at us, figure out a better way to handle multiple
47architectures so we can quit using the symbolic link stuff.  (Imake doesn't
48count.)
49
50The file .depend in the source directory is expected to contain dependencies
51for the source files.  This file is read automatically by make after reading
52the Makefile.
53
54The variable DESTDIR works as before.  It's not set anywhere but will change
55the tree where the file gets installed.
56
57The profiled libraries are no longer built in a different directory than
58the regular libraries.  A new suffix, ".po", is used to denote a profiled
59object, and ".pico" denotes a shared (position-independent) object.
60
61There are various make variables used during the build.
62
63Many variables support a (case sensitive) value of "no" or "yes",
64and are tested with  ${VAR} == "no"  and  ${VAR} != "no" .
65
66
67The basic rule for the variable naming scheme is as follows:
68
69HOST_xxx	A command that runs on the host machine regardless of
70		whether or not the system is being cross compiled, or
71		flags for such a command.
72
73MKxxx		Can be set to "no" to disable functionality, or
74		"yes" to enable it.
75		Usually defaults to "yes", although some variables
76		default to "no".
77		Due to make(1) implementation issues, if a temporary
78		command-line override of a mk.conf(5) or <bsd.own.mk>
79		setting is required whilst still honoring a particular
80		Makefile's setting of MKxxx, use
81			env MKxxx=value make
82		instead of
83			make MKxxx=value
84
85NOxxx		If defined, disables a feature.
86		Not intended for users.
87		This is to allow Makefiles to disable functionality
88		that they don't support (such as missing man pages).
89		NOxxx variables must be defined before <bsd.own.mk>
90		is included.
91
92TOOL_xxx	A tool that is provided as part of the USETOOLS
93		framework.  When not using the USETOOLS framework,
94		TOOL_xxx variables should refer to tools that are
95		already installed on the host system.
96
97The following variables that control how things are made/installed that
98are not set by default. These should not be set by Makefiles; they're for
99the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5))
100or on the make(1) command line:
101
102BUILD 		If defined, 'make install' checks that the targets in the
103		source directories are up-to-date and remakes them if they
104                are out of date, instead of blindly trying to install
105                out of date or non-existent targets.
106
107MAKEVERBOSE	Control how "verbose" the standard make(1) rules are.
108		Default: 2
109		Supported values:
110		    0	Minimal output ("quiet")
111		    1	Describe what is occurring
112		    2	Describe what is occurring and echo the actual command
113		    3	Ignore the effect of the "@" prefix in make commands
114		    4	Trace shell commands using the shell's -x flag
115
116MKATF		If "no", don't build the Automated Testing Framework (ATF),
117		which includes the libatf-c, libatf-c++ and libatf-sh libraries
118		and the various command line tools.  Also, because the build of
119		the libraries is disabled, don't build the NetBSD test suite
120		either.
121		Default: yes
122
123MKBFD		Obsolete, use MKBINUTILS

394		non-root "make install".
395		Default: no

448		designed for improved performance with threaded
449		applications.  The "phkmalloc" allocator as used up
450		before NetBSD-5.0 will be substituted.
451
452USE_KERBEROS	If "no", disables building Kerberos v5
453		support into various system utilities/libraries that

473		stack protection code imposes a performance penalty
474		of about 5%.
475		Default: "no", unless "USE_FORT" is set to "yes"
476
477USE_FORT 	If "yes" turns on substitute wrappers for commonly used
478		functions that do not do bounds checking regularly, but
479		they could in some cases by using the gcc
480		__builtin_object_size() function to determine the buffer
481		size where it is known and detect buffer overflows.
482		These substitute functions are in /usr/include/ssp.
483		Default: depends on the part of the source tree

504COPTS.<prog>
505OBJCCOPTS.<prog>
506LDADD.<prog>
507CPPFLAGS.<prog>
508CXXFLAGS.<prog>	These provide a way to specify additions to the associated
509		variables in a way that applies only to a particular library
510		or program.  <lib> corresponds to the LIB variable set in
511		the library's makefile.  <prog> corresponds to either PROG
512		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
513		set to "-g", "-g" will be added to COPTS only when compiling
514		the crypto library.
515
516The active compiler is selected using the following variables:
517AVAILABLE_COMPILER
518		List of available compiler suites.  Processed in order
519		for selecting the active compiler for each frontend.

526ACTIVE_CC	Active compile suite for the CC frontend.
527SUPPORTED_CC	Compile suite with support for the CC frontend.
528TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"

537The include file <bsd.own.mk> contains source tree configuration parameters,
538such as the owners, groups, etc. for both manual pages and binaries, and
539a few global "feature configuration" parameters.
540
541It has no targets.
542
543To get system-specific configuration parameters, <bsd.own.mk> will try to
544include the file specified by the "MAKECONF" variable.  If MAKECONF is not
545set, or no such file exists, the system make configuration file, /etc/mk.conf
546is included.  These files may define any of the variables described below.
547
548<bsd.own.mk> sets the following variables, if they are not already defined
549(defaults are in brackets):
550
551NETBSDSRCDIR	Top of the NetBSD source tree.
552		If _SRC_TOP_ != "", that will be used as the default,
553		otherwise BSDSRCDIR will be used as the default.
554		Various makefiles within the NetBSD source tree will
555		use this to reference the top level of the source tree.
556
557_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
558		based on the presence of tools/ and build.sh.  This variable
559		is "internal" to <bsd.own.mk>, although its value is only
560		determined once and then propagated to all sub-makes.
561
562_NETBSD_VERSION_DEPENDS
563		A list of files which contain information about
564		the version of the NetBSD being built.  This is
565		defined only if the current directory appears
566		to be inside a NetBSD source tree.  The list of
567		files includes ${NETBSDSRCDIR}/sys/sys/param.h
568		(which contains the kernel version number),
569		${NETBSDSRCDIR}/sys/conf/newvers.sh and
570		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
571		interpret the information in sys/sys/param.h), and
572		${_SRC_TOP_OBJ_}/params (which is an optional file,
573		created by "make build" in ${_SRC_TOP_}/Makefile,
574		containing all the variables that may influence the
575		build).
576
577		Targets that depend on the NetBSD version, or on
578		variables defined at build time, can declare a
579		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
580
581			version.c: ${_NETBSD_VERSION_DEPENDS}
582				commands to create version.c

584BSDSRCDIR	The real path to the system sources, so that 'make obj'
585		will work correctly.  [/usr/src]

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

920
921<bsd.own.mk> is generally useful when building your own Makefiles so that
922they use the same default owners etc. as the rest of the tree.
923
924
925=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
926
927The include file <bsd.clean.mk> defines the clean and cleandir
928targets.  It uses the following variables:
929
930CLEANFILES	Files to remove for both the clean and cleandir targets.
931
932CLEANDIRFILES	Files to remove for the cleandir target, but not for
933		the clean target.
934
935MKCLEANSRC	Controls whether or not the clean and cleandir targets
936		will delete files from both the object directory,
937		${.OBJDIR}, and the source directory, ${.CURDIR}.
938
939		If MKCLEANSRC is set to "no", then the file names in
940		CLEANFILES or CLEANDIRFILES are interpreted relative
941		to the object directory, ${.OBJDIR}.  This is the
942		traditional behaviour.
943
944		If MKCLEANSRC is set to "yes", then the file deletion
945		is performed relative to both the object directory,
946		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
947		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
948		Deleting files from ${.CURDIR} is intended to remove
949		stray output files that had been left in the source
950		directory by an earlier build that did not use object
951		directories.
952
953		The default is MKCLEANSRC=yes.  If you always build with
954		separate object directories, and you are sure that there
955		are no stray files in the source directories, then you
956		may set MKCLEANSRC=no to save some time.
957
958MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
959		will verify that files have been deleted.
960
961		If MKCLEANVERIFY is set to "no", then the files will
962		be deleted using a "rm -f" command, and its success or
963		failure will be ignored.
964
965		If MKCLEANVERIFY is set to "yes", then the success of
966		the "rm -f" command will be verified using an "ls"
967		command.
968
969		The default is MKCLEANVERIFY=yes.  If you are sure that
970		there will be no problems caused by file permissions,
971		read-only file systems, or the like, then you may set
972		MKCLEANVERIFY=no to save some time.
973
974To use the clean and cleandir targets defined in <bsd.clean.mk>, other
975Makefiles or bsd.*.mk files should append file names to the CLEANFILES
976or CLEANDIRFILES variables.  For example:
977
978	    CLEANFILES+= a.out
979	    CLEANDIRFILES+= .depend
980
981	    .include <bsd.clean.mk>
982
983The files listed in CLEANFILES and CLEANDIRFILES must not be
984directories, because the potential risk from running "rm -rf" commands
985in bsd.clean.mk is considered too great.  If you want to recursively
986delete a directory as part of "make clean" or "make cleandir" then you
987need to provide your own target.
988
989=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
990
991The include file <bsd.dep.mk> contains the default targets for building
992.depend files.  It creates .d files from entries in SRCS and DPSRCS
993that are C, C++, or Objective C source files, and builds .depend from the
994.d files.  All other files in SRCS and all of DPSRCS will be used as
995dependencies for the .d files.  In order for this to function correctly,
996it should be .included after all other .mk files and directives that may
997modify SRCS or DPSRCS.  It uses the following variables:
998
999SRCS		List of source files to build the program.
1000
1001DPSRCS		List of source files which are needed for generating
1002		dependencies, but are not needed in ${SRCS}.
1003
1004
1005=-=-=-=-=   bsd.files.mk   =-=-=-=-=
1006
1007The include file <bsd.files.mk> handles the FILES variables and is included
1008from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1009
1010FILES		The list of files to install.
1011
1012CONFIGFILES	Similar semantics to FILES, except that the files
1013		are installed by the `configinstall' target,
1014		not the `install' target.
1015		The FILES* variables documented below also apply.
1016
1017FILESOWN	File owner.  [${BINOWN}]
1018
1019FILESGRP	File group.  [${BINGRP}]
1020
1021FILESMODE	File mode.  [${NONBINMODE}]
1022
1023FILESDIR	The location to install the files.
1024
1025FILESNAME	Optional name to install each file as.
1026
1027FILESOWN_<fn>	File owner of the specific file <fn>.
1028
1029FILESGRP_<fn>	File group of the specific file <fn>.
1030
1031FILESMODE_<fn>	File mode of the specific file <fn>.
1032
1033FILESDIR_<fn>	The location to install the specific file <fn>.
1034
1035FILESNAME_<fn>	Optional name to install <fn> as.
1036
1037FILESBUILD	If this variable is defined, then its value will be
1038		used as the default for all FILESBUILD_<fn> variables.
1039		Otherwise, the default will be "no".
1040
1041FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1042		targets to be built by `realall'.  Users of that variable
1043		should provide a target to build the file.
1044
1045
1046BUILDSYMLINKS	List of two word items:
1047			lnsrc lntgt
1048		For each lnsrc item, create a symlink named lntgt.
1049		The lntgt symlinks are removed by the cleandir target.
1050
1051UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1052		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1053		The source files have a `.uue' suffix, the generated files do
1054		not.
1055
1056UUDECODE_FILES_RENAME_<fn>
1057		Rename the output from the decode to the provided name.

1062
1063=-=-=-=-=   bsd.gcc.mk   =-=-=-=-=
1064
1065The include file <bsd.gcc.mk> computes various parameters related to GCC
1066support libraries.  It defines no targets.  <bsd.own.mk> MUST be included
1067before <bsd.gcc.mk>.
1068
1069The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
1070of which need to know where to find certain GCC support libraries.
1071
1072The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
1073which is generally set by the user.  If EXTERNAL_TOOLCHAIN it set, then
1074the compiler is asked where to find the support libraries, otherwise the
1075support libraries are found in ${DESTDIR}/usr/lib.
1076
1077<bsd.gcc.mk> sets the following variables:
1078
1079_GCC_CRTBEGIN	The full path name to crtbegin.o.
1080
1081_GCC_CRTBEGINS	The full path name to crtbeginS.o.
1082
1083_GCC_CRTEND	The full path name to crtend.o.
1084
1085_GCC_CRTENDS	The full path name to crtendS.o.
1086
1087_GCC_LIBGCCDIR	The directory where libgcc.a is located.
1088
1089
1090=-=-=-=-=   bsd.inc.mk   =-=-=-=-=
1091
1092The include file <bsd.inc.mk> defines the includes target and uses the
1093variables:
1094
1095INCS		The list of include files.
1096
1097INCSDIR		The location to install the include files.
1098
1099INCSNAME	Target name of the include file, if only one; same as
1100		FILESNAME, but for include files.
1101
1102INCSYMLINKS	Similar to SYMLINKS in <bsd.links.mk>, except that these
1103		are installed in the 'includes' target and not the
1104		(much later) 'install' target.
1105
1106INCSNAME_<file>	The name file <file> should be installed as, if not <file>,
1107		same as FILESNAME_<file>, but for include files.
1108
1109
1110=-=-=-=-=   bsd.info.mk   =-=-=-=-=
1111
1112The include file <bsd.info.mk> is used to generate and install GNU Info
1113documentation from respective Texinfo source files.  It defines three
1114implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
1115following variables:
1116
1117TEXINFO		List of Texinfo source files.  Info documentation will
1118		consist of single files with the extension replaced by
1119		.info.
1120
1121INFOFLAGS	Flags to pass to makeinfo.  []
1122
1123
1124=-=-=-=-=   bsd.kernobj.mk   =-=-=-=-=
1125
1126The include file <bsd.kernobj.mk> defines variables related to the
1127location of kernel sources and object directories.
1128
1129KERNSRCDIR	Is the location of the top of the kernel src.
1130		[${_SRC_TOP_}/sys]
1131
1132KERNARCHDIR	Is the location of the machine dependent kernel sources.
1133		[arch/${MACHINE}]
1134
1135KERNCONFDIR	Is where the configuration files for kernels are found.
1136		[${KERNSRCDIR}/${KERNARCHDIR}/conf]
1137
1138KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
1139		instance will be compiled in ${KERNOBJDIR}/GENERIC.
1140		The default value is
1141		${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
1142		if it exists or the target 'obj' is being made.
1143		Otherwise the default is
1144		${KERNSRCDIR}/${KERNARCHDIR}/compile.
1145
1146It is important that Makefiles (such as those under src/distrib) that
1147wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
1148rather than make assumptions about the location of the compiled kernel.
1149
1150
1151=-=-=-=-=   bsd.kinc.mk   =-=-=-=-=
1152
1153The include file <bsd.kinc.mk> defines the many targets (includes,
1154subdirectories, etc.), and is used by kernel makefiles to handle
1155include file installation.  It is intended to be included alone, by
1156kernel Makefiles.  It uses similar variables to <bsd.inc.mk>.
1157Please see <bsd.kinc.mk> for more details, and keep the documentation
1158in that file up to date.
1159
1160=-=-=-=-=   bsd.syscall.mk =-=-=-=-=
1161
1162The include file <bsd.syscall.mk> contains the logic to create syscall
1163files for various emulations. It includes <bsd.kinc.mk> to handle the
1164rest of the targets.
1165
1166=-=-=-=-=   bsd.lib.mk   =-=-=-=-=
1167
1168The include file <bsd.lib.mk> has support for building libraries.  It has
1169the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1170includes, install, lint, and tags.  Additionally, it has a checkver target
1171which checks for installed shared object libraries whose version is greater
1172that the version of the source. It has a limited number of suffixes,
1173consistent with the current needs of the BSD tree.  <bsd.lib.mk> includes
1174<bsd.shlib.mk> to get shared library parameters.
1175
1176It sets/uses the following variables:
1177
1178LIB		The name of the library to build.
1179
1180LIBDIR		Target directory for libraries.
1181
1182MKARZERO	Normally, ar(1) sets the timestamps, uid, gid and
1183		permissions in files inside its archives to those of
1184		the file it was fed. This leads to non-reproduceable
1185		builds. If MKARZERO is set to "yes" (default is the
1186		same as MKREPRO, or "no" if MKREPRO is not defined),
1187		then the "D" flag is passed to ar, causing the
1188		timestamp, uid and gid to be zeroed and the file
1189		permissions to be set to 644. This allows .a files
1190		from different builds to be bit identical.
1191
1192SHLIBINSTALLDIR	Target directory for shared libraries if ${USE_SHLIBDIR}
1193		is not "no".
1194
1195SHLIB_MAJOR
1196SHLIB_MINOR
1197SHLIB_TEENY	Major, minor, and teeny version numbers of shared library
1198
1199USE_SHLIBDIR	If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
1200		as the path to install shared libraries to.
1201		USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
1202		Default: no
1203
1204LIBISMODULE	If not "no", install as ${LIB}.so (without the "lib" prefix),
1205		and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
1206		MKPROFILE=no MKSTATICLIB=no".
1207		Default: no
1208
1209LIBISPRIVATE	If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
1210		MKPROFILE=no", and don't install the (.a) library.
1211		This is useful for "build only" helper libraries.
1212		Default: no
1213
1214LIBISCXX	If not "no", Use ${CXX} instead of ${CC} to link
1215		shared libraries.
1216		This is useful for C++ libraries.
1217		Default: no
1218
1219LINTLIBDIR	Target directory for lint libraries.
1220
1221LIBGRP		Library group.
1222
1223LIBOWN		Library owner.
1224
1225LIBMODE		Library mode.
1226
1227LDADD		Additional loader objects.
1228
1229MAN		The manual pages to be installed (use a .1 - .9 suffix).
1230
1231NOCHECKVER_<library>
1232NOCHECKVER	If set, disables checking for installed shared object
1233		libraries with versions greater than the source.  A
1234		particular library name, without the "lib" prefix, may
1235		be appended to the variable name to disable the check for
1236		only that library.
1237
1238SRCS		List of source files to build the library.  Suffix types
1239		.s, .c, and .f are supported.  Note, .s files are preferred
1240		to .c files of the same name.  (This is not the default for
1241		versions of make.)
1242
1243LIBDPLIBS	A list of the tuples:
1244			libname  path-to-srcdir-of-libname
1245
1246		For each tuple;
1247		     *	LIBDO.libname contains the .OBJDIR of the library
1248			`libname', and if it is not set it is determined
1249			from the srcdir and added to MAKEOVERRIDES (the
1250			latter is to allow for build time optimization).
1251		     *	LDADD gets  -L${LIBDO.libname} -llibname    added.
1252		     *	DPADD gets  ${LIBDO.libname}/liblibname.so  or
1253				    ${LIBDO.libname}/liblibname.a   added.
1254
1255		The special value "_external" for LIBDO.lib makes the
1256		build system to assume the library comes from outside
1257		of the NetBSD source tree and only causes -llibname
1258		to be added to LDADD.
1259
1260		This variable may be used for individual libraries, as
1261		well as in parent directories to cache common libraries
1262		as a build-time optimization.
1263
1264The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1265if it exists, as well as the include file <bsd.man.mk>.
1266
1267It has rules for building profiled objects; profiled libraries are
1268built by default.
1269
1270Libraries are ranlib'd when made.
1271
1272
1273=-=-=-=-=   bsd.links.mk   =-=-=-=-=
1274
1275The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1276and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1277
1278LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1279is used. The defaults may be modified by other bsd.*.mk files which
1280include bsd.links.mk.  In the future, these variables may be replaced
1281by a method for explicitly recording hard links in a metadata log.
1282
1283LINKS		The list of hard links, consisting of pairs of paths:
1284			source-file target-file
1285		${DESTDIR} is prepended to both paths before linking.
1286		For example, to link /bin/test and /bin/[, use:
1287			LINKS=/bin/test /bin/[
1288
1289CONFIGLINKS	Similar semantics to LINKS, except that the links
1290		are installed by the `configinstall' target,
1291		not the `install' target.
1292
1293SYMLINKS	The list of symbolic links, consisting of pairs of paths:
1294			source-file target-file
1295		${DESTDIR} is only prepended to target-file before linking.
1296		For example, to symlink /usr/bin/tar to /bin/tar resulting
1297		in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1298			SYMLINKS=/bin/tar /usr/bin/tar
1299
1300CONFIGSYMLINKS	Similar semantics to SYMLINKS, except that the symbolic links
1301		are installed by the `configinstall' target,
1302		not the `install' target.
1303
1304LINKSOWN	Link owner.  [${BINOWN}]
1305
1306LINKSGRP	Link group.  [${BINGRP}]
1307
1308LINKSMODE	Link mode.  [${NONBINMODE}]
1309
1310LINKSOWN_<fn>	Link owner of the specific file <fn>.
1311
1312LINKSGRP_<fn>	Link group of the specific file <fn>.
1313
1314LINKSMODE_<fn>	Link mode of the specific file <fn>.
1315
1316
1317=-=-=-=-=   bsd.man.mk   =-=-=-=-=
1318
1319The include file <bsd.man.mk> handles installing manual pages and their
1320links.
1321
1322It has a three targets:
1323
1324	catinstall:
1325		Install the preformatted manual pages and their links.
1326	htmlinstall:
1327		Install the HTML manual pages and their links.
1328	maninstall:
1329		Install the manual page sources and their links.
1330
1331It sets/uses the following variables:
1332
1333MANDIR		Base path for manual installation.
1334
1335MANGRP		Manual group.
1336
1337MANOWN		Manual owner.
1338
1339MANMODE		Manual mode.
1340
1341MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
1342		or "/tahoe" for machine specific manual pages.
1343
1344MAN		The manual pages to be installed (use a .1 - .9 suffix).
1345
1346MLINKS		List of manual page links (using a .1 - .9 suffix).  The
1347		linked-to file must come first, the linked file second,
1348		and there may be multiple pairs.
1349
1350The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1351it exists.
1352
1353
1354=-=-=-=-=   bsd.obj.mk   =-=-=-=-=
1355
1356The include file <bsd.obj.mk> defines targets related to the creation
1357and use of separated object and source directories.
1358
1359If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1360${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1361it exists.  Otherwise make(1) looks for the existence of a
1362subdirectory (or a symlink to a directory) of the source directory
1363into which built targets should be placed.  If an environment variable
1364named MAKEOBJDIR is set, make(1) uses its value as the name of the
1365object directory; failing that, make first looks for a subdirectory
1366named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1367
1368Object directories are not created automatically by make(1) if they
1369don't exist; you need to run a separate "make obj".  (This will happen
1370during a top-level build if "MKOBJDIRS" is set to a value other than
1371"no").  When the source directory is a subdirectory of ${BSDSRCDIR} --
1372and this is determined by a simple string prefix comparison -- object
1373directories are created in a separate object directory tree, and a
1374symlink to the object directory in that tree is created in the source
1375directory; otherwise, "make obj" assumes that you're not in the main
1376source tree and that it's not safe to use a separate object tree.
1377
1378Several variables used by <bsd.obj.mk> control exactly what
1379directories and links get created during a "make obj":
1380
1381MAKEOBJDIR	If set, this is the component name of the object
1382		directory.
1383
1384OBJMACHINE	If this is set but MAKEOBJDIR is not set, creates
1385		object directories or links named "obj.${MACHINE}";
1386		otherwise, just creates ones named "obj".
1387
1388USR_OBJMACHINE  If set, and the current directory is a subdirectory of
1389		${BSDSRCDIR}, create object directory in the
1390		corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1391		otherwise, create it in the corresponding subdirectory
1392		of ${BSDOBJDIR}
1393
1394BUILDID		If set, the contents of this variable are appended
1395		to the object directory name.  If OBJMACHINE is also
1396		set, ".${BUILDID}" is added after ".${MACHINE}".
1397
1398
1399=-=-=-=-=   bsd.prog.mk   =-=-=-=-=
1400
1401The include file <bsd.prog.mk> handles building programs from one or
1402more source files, along with their manual pages.  It has a limited number
1403of suffixes, consistent with the current needs of the BSD tree.
1404<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1405
1406It has eight targets:
1407
1408	all:
1409		build the program and its manual page.  This also
1410		creates a GDB initialization file (.gdbinit) in
1411		the objdir.  The .gdbinit file sets the shared library
1412		prefix to ${DESTDIR} to facilitate cross-debugging.
1413	clean:
1414		remove the program, any object files and the files a.out,
1415		Errs, errs, mklog, and ${PROG}.core.
1416	cleandir:
1417		remove all of the files removed by the target clean, as
1418		well as .depend, tags, and any manual pages.
1419		`distclean' is a synonym for `cleandir'.
1420	depend:
1421		make the dependencies for the source files, and store
1422		them in the file .depend.
1423	includes:
1424		install any header files.
1425	install:
1426		install the program and its manual pages; if the Makefile
1427		does not itself define the target install, the targets
1428		beforeinstall and afterinstall may also be used to cause
1429		actions immediately before and after the install target
1430		is executed.
1431	lint:
1432		run lint on the source files
1433	tags:
1434		create a tags file for the source files.
1435
1436It sets/uses the following variables:
1437
1438BINGRP		Binary group.
1439
1440BINOWN		Binary owner.
1441
1442BINMODE		Binary mode.
1443
1444CLEANDIRFILES	Additional files to remove for the cleandir target.
1445
1446CLEANFILES	Additional files to remove for the clean and cleandir targets.
1447
1448CONFIGOPTS	Additional flags to config(1) when building kernels.
1449
1450COPTS		Additional flags to the compiler when creating C objects.
1451
1452COPTS.<fn>	Additional flags to the compiler when creating the
1453		C objects for <fn>.
1454		For <fn>.[ly], "<fn>.c" must be used.
1455
1456CPUFLAGS	Additional flags to the compiler/assembler to select
1457		CPU instruction set options, CPU tuning options, etc.
1458
1459CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1460		For <fn>.[ly], "<fn>.c" must be used.
1461
1462CPPFLAGS	Additional flags to the C pre-processor.
1463
1464CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1465		For <fn>.[ly], "<fn>.c" must be used.
1466
1467GDBINIT		List of GDB initialization files to add to "source"
1468		directives in the .gdbinit file that is created in the
1469		objdir.
1470
1471LDADD		Additional loader objects.  Usually used for libraries.
1472		For example, to load with the compatibility and utility
1473		libraries, use:
1474
1475			LDADD+=-lutil -lcompat
1476
1477LDFLAGS		Additional linker flags (passed to ${CC} during link).
1478
1479LINKS		See <bsd.links.mk>
1480
1481OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1482
1483OBJCOPTS.<fn>	Additional flags to the compiler when creating the

1485		For <fn>.[ly], "<fn>.c" must be used.
1486
1487SYMLINKS	See <bsd.links.mk>
1488
1489MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1490		defined, "MAN=${PROG}.1" is assumed.
1491
1492PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1493		time, with the value of this variable as args to paxctl(1).
1494
1495PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1496
1497PROG		The name of the program to build.  If not supplied, nothing
1498		is built.
1499
1500PROG_CXX	If defined, the name of the program to build.  Also
1501		causes <bsd.prog.mk> to link the program with the C++
1502		compiler rather than the C compiler.  PROG_CXX overrides
1503		the value of PROG if PROG is also set.
1504
1505PROGNAME	The name that the above program will be installed as, if
1506		different from ${PROG}.
1507
1508SRCS		List of source files to build the program.  If SRCS is not
1509		defined, it's assumed to be ${PROG}.c.
1510
1511DPSRCS		List of source files which are needed for generating
1512		dependencies, but are not needed in ${SRCS}.
1513
1514DPADD		Additional dependencies for the program.  Usually used for

1516		utility libraries use:
1517
1518			DPADD+=${LIBCOMPAT} ${LIBUTIL}
1519

1672SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1673		strings, using xstr(1). Note that this will not work with
1674		parallel makes.
1675
1676STRIPFLAG	The flag passed to the install program to cause the binary
1677		to be stripped.
1678
1679SUBDIR		A list of subdirectories that should be built as well.
1680		Each of the targets will execute the same target in the
1681		subdirectories.
1682
1683SCRIPTS		A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1684		These are installed exactly like programs.
1685
1686SCRIPTSDIR	The location to install the scripts.  Each script can be
1687		installed to a separate path by setting SCRIPTSDIR_<script>.
1688
1689SCRIPTSNAME	The name that the above program will be installed as, if
1690		different from ${SCRIPTS}. These can be further specialized
1691		by setting SCRIPTSNAME_<script>.
1692
1693FILES		See description of <bsd.files.mk>.
1694
1695SHLINKDIR	Target directory for shared linker.  See description of
1696		<bsd.own.mk> for additional information about this variable.
1697
1698The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1699if it exists, as well as the include file <bsd.man.mk>.
1700
1701Some simple examples:
1702
1703To build foo from foo.c with a manual page foo.1, use:
1704
1705	PROG=	foo
1706
1707	.include <bsd.prog.mk>
1708
1709To build foo from foo.c with a manual page foo.2, add the line:
1710
1711	MAN=	foo.2
1712
1713If foo does not have a manual page at all, add the line:
1714
1715	MKMAN=	no
1716
1717If foo has multiple source files, add the line:
1718
1719	SRCS=	a.c b.c c.c d.c
1720
1721
1722=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1723
1724The include file <bsd.rpc.mk> contains a makefile fragment used to
1725construct source files built by rpcgen.
1726
1727The following macros may be defined in makefiles which include
1728<bsd.rpc.mk> in order to control which files get built and how they
1729are to be built:
1730
1731RPC_INCS:	construct .h file from .x file
1732RPC_XDRFILES:	construct _xdr.c from .x file
1733		(for marshalling/unmarshalling data types)
1734RPC_SVCFILES:	construct _svc.c from .x file
1735		(server-side stubs)
1736RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1737
1738RPC_XDIR:	Directory containing .x/.h files
1739
1740
1741=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1742
1743The include file <bsd.shlib.mk> computes parameters for shared library
1744installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1745included before <bsd.shlib.mk>.
1746
1747<bsd.own.mk> sets the following variables, if they are not already defined
1748(defaults are in brackets):
1749
1750SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1751		instead of ${LIBDIR} as the base path for shared library
1752		installation.  [/lib]
1753
1754SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1755		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1756		for all others.]
1757
1758_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1759		otherwise set to ${LIBDIR}
1760
1761SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1762
1763SHLINKDIR	Path to use for shared linker when building a program.
1764		[/libexec for programs in /bin and /sbin, /usr/libexec for
1765		all others.]
1766
1767
1768=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1769
1770The include file <bsd.subdir.mk> contains the default targets for building
1771subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1772clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1773following variables:
1774
1775NOSUBDIR	If this variable is defined, then the SUBDIR variable
1776		will be ignored and subdirectories will not be processed.
1777
1778SUBDIR		For all of the directories listed in ${SUBDIR}, the
1779		specified directory will be visited and the target made.
1780
1781		As a special case, the use of a token .WAIT as an
1782		entry in SUBDIR acts as a synchronization barrier
1783		when multiple make jobs are run; subdirs before the
1784		.WAIT must complete before any subdirs after .WAIT are
1785		started.  See make(1) for some caveats on use of .WAIT
1786		and other special sources.
1787
1788
1789=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1790
1791The include file <bsd.x11.mk> contains parameters and targets for
1792cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}.
1793It should be included after the general Makefile contents but before
1794the include files such as <bsd.prog.mk> and <bsd.lib.mk>.
1795
1796It provides the following targets:
1797	.man.1 .man.3 .man.4 .man.5 .man.7:
1798		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1799		these rules convert from X11's manual page source
1800		into an mdoc.old source file.
1801
1802It sets the following variables:
1803
1804BINDIR			Set to ${X11BINDIR}.
1805			To override, define after including <bsd.x11.mk>
1806
1807LIBDIR			Set to ${X11USRLIBDIR}.
1808			To override, define after including <bsd.x11.mk>
1809
1810MANDIR			Set to ${X11MANDIR}.
1811			To override, define after including <bsd.x11.mk>
1812
1813CPPFLAGS		Appended with definitions to include from
1814			${DESTDIR}${X11INCDIR}
1815
1816LDFLAGS			Appended with definitions to link from
1817			${DESTDIR}${X11USRLIBDIR}

1823X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1824
1825X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1826
1827X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1828

1830
1831X11FLAGS.THREADS	Equivalent to X11's THREADS_DEFINES.
1832
1833X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1834
1835X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1836
1837X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1838
1839It uses the following variables:
1840
1841APPDEFS			List of app-default files to install.
1842
1843CPPSCRIPTS		List of files/scripts to run through cpp(1)
1844			and then ${X11TOOL_UNXCOMM}.  The source files

1846
1847CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1848
1849CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.

1852=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1853
1854The following files are described here for completion, but they are not
1855supposed to be included directly from other Makefiles; they are used
1856internally by other system files.
1857
1858=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1859
1860The include file <bsd.sys.mk> is used by other system mk files and
