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

430		the affect is equivalent to -x option of ld(1). If "no",
431		strip only temporary local symbols; the affect is equivalent
432		to -X option of ld(1). Keeping non-temporary local symbols
433		such as static function names is useful on using DTrace for
434		userland libraries and getting a backtrace from a rump kernel
435		loading shared libraries.

458MKUPDATE 	If not "no", 'make install' only installs targets that are
459		more recently modified in the source directories that their
460		installed counterparts.
461		Default: no
462

465		enables creation of X sets.
466		Default: no
467
468MKX11FONTS	If not "no", do not build or install the X fonts.  The xfont
469		set is still created but will be empty.

471
472MKX11MOTIF:	If "yes", build the native X11 libGLw with Motif stubs.  If

487MKRUMP		If "no", do not build and install rump related headers,
488		libraries, and programs.
489		Default: yes
490
491USE_HESIOD	If "no", disables building Hesiod support into
492		various system utilities/libraries that support it.
493		If ${MKHESIOD} is "no", USE_HESIOD will also be
494		forced to "no".
495
496USE_INET6	If "no", disables building INET6 (IPv6) support into
497		various system utilities/libraries that support it.
498		If ${MKINET6} is "no", USE_INET6 will also be
499		forced to "no".
500
501USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
502		designed for improved performance with threaded
503		applications.  The "phkmalloc" allocator as used up
504		before NetBSD-5.0 will be substituted.
505
506USE_KERBEROS	If "no", disables building Kerberos v5
507		support into various system utilities/libraries that
508		support it.  If ${MKKERBEROS} is "no", USE_KERBEROS

522		also be forced to "no".
523		Default: no
524
525USE_SSP		If "no", disables GCC stack protection code, which
526		detects stack overflows and aborts the program. The
527		stack protection code imposes a performance penalty
528		of about 5%.
529		Default: "no", unless "USE_FORT" is set to "yes"
530
531NOSSP		Don't compile with stack protector during build.
532		It is set internally for standalone programs.
533
534USE_FORT 	If "yes" turns on substitute wrappers for commonly used
535		functions that do not do bounds checking regularly, but
536		they could in some cases by using the gcc
537		__builtin_object_size() function to determine the buffer
538		size where it is known and detect buffer overflows.
539		These substitute functions are in /usr/include/ssp.
540		Default: depends on the part of the source tree
541
542NOFORT		Don't compile with substitute wrappers during build.
543		It is set internally for standalone programs.
544
545USE_YP		If "no", disables building YP (NIS) support into
546		various system utilities/libraries that support it.
547		If ${MKYP} is "no", USE_YP will also be forced to "no".
548
549USE_PIGZGZIP	If "no", use the host "gzip" program to compress things.
550		Otherwise, build tools/pigz, set TOOL_GZIP=${TOOL_PIGZ},
551		and use nbpigz to compress things.
552		Default: "no".

555OBJCOPTS.lib<lib>
556LDADD.lib<lib>
557CPPFLAGS.lib<lib>
558CXXFLAGS.lib<lib>
559COPTS.<prog>
560OBJCCOPTS.<prog>
561LDADD.<prog>
562CPPFLAGS.<prog>
563CXXFLAGS.<prog>	These provide a way to specify additions to the associated
564		variables in a way that applies only to a particular library
565		or program.  <lib> corresponds to the LIB variable set in
566		the library's makefile.  <prog> corresponds to either PROG
567		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
568		set to "-g", "-g" will be added to COPTS only when compiling
569		the crypto library.
570
571The active compiler is selected using the following variables:
572AVAILABLE_COMPILER
573		List of available compiler suites.  Processed in order
574		for selecting the active compiler for each frontend.
575HAVE_PCC	If defined, PCC is present and enabled.
576HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
577UNSUPPORTED_COMPILER.xxx
578		If defined, the support for compiler "xxx" is disabled.
579
580For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
581ACTIVE_CC	Active compile suite for the CC frontend.
582SUPPORTED_CC	Compile suite with support for the CC frontend.
583TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
584
585=-=-=-=-=   sys.mk   =-=-=-=-=
586
587The include file <sys.mk> has the default rules for all makes, in the BSD
588environment or otherwise.  You probably don't want to touch this file.
589
590=-=-=-=-=   bsd.own.mk   =-=-=-=-=
591
592The include file <bsd.own.mk> contains source tree configuration parameters,
593such as the owners, groups, etc. for both manual pages and binaries, and
594a few global "feature configuration" parameters.
595
596It has no targets.
597
598To get system-specific configuration parameters, <bsd.own.mk> will try to
599include the file specified by the "MAKECONF" variable.  If MAKECONF is not
600set, or no such file exists, the system make configuration file, /etc/mk.conf
601is included.  These files may define any of the variables described below.
602
603<bsd.own.mk> sets the following variables, if they are not already defined
604(defaults are in brackets):
605
606NETBSDSRCDIR	Top of the NetBSD source tree.
607		If _SRC_TOP_ != "", that will be used as the default,
608		otherwise BSDSRCDIR will be used as the default.
609		Various makefiles within the NetBSD source tree will
610		use this to reference the top level of the source tree.
611
612_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
613		based on the presence of tools/ and build.sh.  This variable
614		is "internal" to <bsd.own.mk>, although its value is only
615		determined once and then propagated to all sub-makes.
616
617_NETBSD_VERSION_DEPENDS
618		A list of files which contain information about
619		the version of the NetBSD being built.  This is
620		defined only if the current directory appears
621		to be inside a NetBSD source tree.  The list of
622		files includes ${NETBSDSRCDIR}/sys/sys/param.h
623		(which contains the kernel version number),
624		${NETBSDSRCDIR}/sys/conf/newvers.sh and
625		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
626		interpret the information in sys/sys/param.h), and
627		${_SRC_TOP_OBJ_}/params (which is an optional file,
628		created by "make build" in ${_SRC_TOP_}/Makefile,
629		containing all the variables that may influence the
630		build).
631
632		Targets that depend on the NetBSD version, or on
633		variables defined at build time, can declare a
634		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
635
636			version.c: ${_NETBSD_VERSION_DEPENDS}
637				commands to create version.c
638
639BSDSRCDIR	The real path to the system sources, so that 'make obj'
640		will work correctly.  [/usr/src]

722
723X11USRLIBDIR	X11 library directory.  [${X11ROOTDIR}/lib]
724
725STRIPFLAG	The flag passed to the install program to cause the binary
726		to be stripped.  This is to be used when building your
727		own install script so that the entire system can be made
728		stripped/not-stripped using a single knob.  []
729
730COPY		The flag passed to the install program to cause the binary
731		to be copied rather than moved.  This is to be used when
732		building our own install script so that the entire system
733		can either be installed with copies, or with moves using
734		a single knob.  [-c]
735
736MAKEDIRTARGETENV
737		Environment variables passed to the child make process
738		invoked by MAKEDIRTARGET.
739
740MAKEDIRTARGET dir target [params]
741		Runs "cd $${dir} && ${MAKE} [params] $${target}",
742		displaying a "pretty" message whilst doing so.
743
744RELEASEMACHINEDIR
745		Subdirectory used below RELEASEDIR when building
746		a release.  [${MACHINE}]
747
748RELEASEMACHINE	Subdirectory or path component used for the following
749		paths:
750			distrib/${RELEASEMACHINE}
751			distrib/notes/${RELEASEMACHINE}
752			etc/etc.${RELEASEMACHINE}
753		Used when building a release.  [${MACHINE}]
754
755Additionally, the following variables may be set by <bsd.own.mk> or in a
756make configuration file to modify the behavior of the system build
757process (default values are in brackets along with comments, if set by
758<bsd.own.mk>):
759
760USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
761		be used as part of a build in progress.
762		Supported values:
763
764		yes	Use the tools from TOOLDIR.
765			Must be set to this if cross-compiling.
766
767		no	Do not use the tools from TOOLDIR, but refuse to
768			build native compilation tool components that are
769			version-specific for that tool.
770
771		never	Do not use the tools from TOOLDIR, even when
772			building native tool components.  This is similar to
773			the traditional NetBSD build method, but does not
774			verify that the compilation tools in use are
775			up-to-date enough in order to build the tree
776			successfully.  This may cause build or runtime
777			problems when building the whole NetBSD source tree.
778
779		Default: "yes" if building all or part of a whole NetBSD
780		source tree (detected automatically); "no" otherwise
781		(to preserve traditional semantics of the <bsd.*.mk>
782		make(1) include files).
783
784OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
785		use ELF -- currently all architectures].
786
787TOOLCHAIN_MISSING
788		If not "no", this indicates that the platform being built
789		does not have a working in-tree toolchain.  If the
790		${MACHINE_ARCH} in question falls into this category,
791		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
792		Otherwise, the variable is unconditionally assigned the
793		value "no".
794		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
795		unconditionally assigned the value "no".
796
797EXTERNAL_TOOLCHAIN
798		This variable is not directly set by <bsd.own.mk>, but
799		including <bsd.own.mk> is the canonical way to gain
800		access to this variable.  The variable should be defined
801		either in the user's environment or in the user's mk.conf
802		file.  If defined, this variable indicates the root of
803		an external toolchain which will be used to build the
804		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
805		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
806		cross-compile framework.
807
808		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
809		assigned the value "no", since the external version of the
810		compiler may not be able to build the library components of
811		the in-tree compiler.
812
813		This variable should be used in conjunction with an appropiate
814		HAVE_GCC or HAVE_LLVM setting to control the compiler flags.
815
816		NOTE: This variable is not yet used in as many places as
817		it should be.  Expect the exact semantics of this variable
818		to change in the short term as parts of the cross-compile
819		framework continue to be cleaned up.
820
821The following variables are defined to commands to perform the
822appropriate operation, with the default in [brackets].  Note that
823the defaults change if USETOOLS == "yes":
824
825TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

973list of what ports can be built for it.  This keeps those definitions in
974centralized place.
975
976<bsd.own.mk> is generally useful when building your own Makefiles so that
977they use the same default owners etc. as the rest of the tree.
978
979
980=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
981
982The include file <bsd.clean.mk> defines the clean and cleandir
983targets.  It uses the following variables:
984
985CLEANFILES	Files to remove for both the clean and cleandir targets.
986
987CLEANDIRFILES	Files to remove for the cleandir target, but not for
988		the clean target.
989
990MKCLEANSRC	Controls whether or not the clean and cleandir targets
991		will delete files from both the object directory,
992		${.OBJDIR}, and the source directory, ${.CURDIR}.
993
994		If MKCLEANSRC is set to "no", then the file names in
995		CLEANFILES or CLEANDIRFILES are interpreted relative
996		to the object directory, ${.OBJDIR}.  This is the
997		traditional behaviour.
998
999		If MKCLEANSRC is set to "yes", then the file deletion
1000		is performed relative to both the object directory,
1001		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
1002		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
1003		Deleting files from ${.CURDIR} is intended to remove
1004		stray output files that had been left in the source
1005		directory by an earlier build that did not use object
1006		directories.
1007
1008		The default is MKCLEANSRC=yes.  If you always build with
1009		separate object directories, and you are sure that there
1010		are no stray files in the source directories, then you
1011		may set MKCLEANSRC=no to save some time.
1012
1013MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
1014		will verify that files have been deleted.
1015
1016		If MKCLEANVERIFY is set to "no", then the files will
1017		be deleted using a "rm -f" command, and its success or
1018		failure will be ignored.
1019
1020		If MKCLEANVERIFY is set to "yes", then the success of
1021		the "rm -f" command will be verified using an "ls"
1022		command.
1023
1024		The default is MKCLEANVERIFY=yes.  If you are sure that
1025		there will be no problems caused by file permissions,
1026		read-only file systems, or the like, then you may set
1027		MKCLEANVERIFY=no to save some time.
1028
1029To use the clean and cleandir targets defined in <bsd.clean.mk>, other
1030Makefiles or bsd.*.mk files should append file names to the CLEANFILES
1031or CLEANDIRFILES variables.  For example:
1032
1033	    CLEANFILES+= a.out
1034	    CLEANDIRFILES+= .depend
1035
1036	    .include <bsd.clean.mk>
1037
1038The files listed in CLEANFILES and CLEANDIRFILES must not be
1039directories, because the potential risk from running "rm -rf" commands
1040in bsd.clean.mk is considered too great.  If you want to recursively
1041delete a directory as part of "make clean" or "make cleandir" then you
1042need to provide your own target.
1043
1044=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
1045
1046The include file <bsd.dep.mk> contains the default targets for building
1047.depend files.  It creates .d files from entries in SRCS and DPSRCS
1048that are C, C++, or Objective C source files, and builds .depend from the
1049.d files.  All other files in SRCS and all of DPSRCS will be used as
1050dependencies for the .d files.  In order for this to function correctly,
1051it should be .included after all other .mk files and directives that may
1052modify SRCS or DPSRCS.  It uses the following variables:
1053
1054SRCS		List of source files to build the program.

1060=-=-=-=-=   bsd.files.mk   =-=-=-=-=
1061
1062The include file <bsd.files.mk> handles the FILES variables and is included
1063from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1064
1065FILES		The list of files to install.
1066
1067CONFIGFILES	Similar semantics to FILES, except that the files
1068		are installed by the `configinstall' target,
1069		not the `install' target.
1070		The FILES* variables documented below also apply.
1071
1072FILESOWN	File owner.  [${BINOWN}]
1073
1074FILESGRP	File group.  [${BINGRP}]
1075
1076FILESMODE	File mode.  [${NONBINMODE}]
1077
1078FILESDIR	The location to install the files.
1079
1080FILESNAME	Optional name to install each file as.
1081
1082FILESOWN_<fn>	File owner of the specific file <fn>.
1083
1084FILESGRP_<fn>	File group of the specific file <fn>.
1085
1086FILESMODE_<fn>	File mode of the specific file <fn>.
1087
1088FILESDIR_<fn>	The location to install the specific file <fn>.
1089
1090FILESNAME_<fn>	Optional name to install <fn> as.
1091
1092FILESBUILD	If this variable is defined, then its value will be
1093		used as the default for all FILESBUILD_<fn> variables.
1094		Otherwise, the default will be "no".
1095
1096FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1097		targets to be built by `realall'.  Users of that variable
1098		should provide a target to build the file.
1099
1100
1101BUILDSYMLINKS	List of two word items:
1102			lnsrc lntgt
1103		For each lnsrc item, create a symlink named lntgt.
1104		The lntgt symlinks are removed by the cleandir target.
1105
1106UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1107		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1108		The source files have a `.uue' suffix, the generated files do
1109		not.
1110
1111UUDECODE_FILES_RENAME_<fn>
1112		Rename the output from the decode to the provided name.
1113		
1114		*NOTE: These files are simply decoded, with no install or other
1115		       rule applying implicitly except being added to the clean
1116		       target.
1117
1118=-=-=-=-=   bsd.gcc.mk   =-=-=-=-=
1119
1120The include file <bsd.gcc.mk> computes various parameters related to GCC
1121support libraries.  It defines no targets.  <bsd.own.mk> MUST be included
1122before <bsd.gcc.mk>.
1123
1124The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
1125of which need to know where to find certain GCC support libraries.
1126
1127The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
1128which is generally set by the user.  If EXTERNAL_TOOLCHAIN it set, then
1129the compiler is asked where to find the support libraries, otherwise the
1130support libraries are found in ${DESTDIR}/usr/lib.
1131
1132<bsd.gcc.mk> sets the following variables:
1133
1134_GCC_CRTBEGIN	The full path name to crtbegin.o.
1135
1136_GCC_CRTBEGINS	The full path name to crtbeginS.o.
1137
1138_GCC_CRTEND	The full path name to crtend.o.
1139
1140_GCC_CRTENDS	The full path name to crtendS.o.
1141
1142_GCC_LIBGCCDIR	The directory where libgcc.a is located.
1143
1144
1145=-=-=-=-=   bsd.inc.mk   =-=-=-=-=
1146
1147The include file <bsd.inc.mk> defines the includes target and uses the
1148variables:
1149
1150INCS		The list of include files.
1151
1152INCSDIR		The location to install the include files.
1153
1154INCSNAME	Target name of the include file, if only one; same as
1155		FILESNAME, but for include files.
1156
1157INCSYMLINKS	Similar to SYMLINKS in <bsd.links.mk>, except that these
1158		are installed in the 'includes' target and not the
1159		(much later) 'install' target.
1160
1161INCSNAME_<file>	The name file <file> should be installed as, if not <file>,
1162		same as FILESNAME_<file>, but for include files.
1163
1164
1165=-=-=-=-=   bsd.info.mk   =-=-=-=-=
1166
1167The include file <bsd.info.mk> is used to generate and install GNU Info
1168documentation from respective Texinfo source files.  It defines three
1169implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
1170following variables:
1171
1172TEXINFO		List of Texinfo source files.  Info documentation will
1173		consist of single files with the extension replaced by
1174		.info.
1175
1176INFOFLAGS	Flags to pass to makeinfo.  []
1177
1178
1179=-=-=-=-=   bsd.kernobj.mk   =-=-=-=-=
1180
1181The include file <bsd.kernobj.mk> defines variables related to the
1182location of kernel sources and object directories.
1183
1184KERNSRCDIR	Is the location of the top of the kernel src.
1185		[${_SRC_TOP_}/sys]
1186
1187KERNARCHDIR	Is the location of the machine dependent kernel sources.
1188		[arch/${MACHINE}]
1189
1190KERNCONFDIR	Is where the configuration files for kernels are found.
1191		[${KERNSRCDIR}/${KERNARCHDIR}/conf]
1192
1193KERNOBJDIR	Is the kernel build directory.  The kernel GENERIC for
1194		instance will be compiled in ${KERNOBJDIR}/GENERIC.
1195		The default value is
1196		${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
1197		if it exists or the target 'obj' is being made.
1198		Otherwise the default is
1199		${KERNSRCDIR}/${KERNARCHDIR}/compile.
1200
1201It is important that Makefiles (such as those under src/distrib) that
1202wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
1203rather than make assumptions about the location of the compiled kernel.
1204
1205
1206=-=-=-=-=   bsd.kinc.mk   =-=-=-=-=
1207
1208The include file <bsd.kinc.mk> defines the many targets (includes,
1209subdirectories, etc.), and is used by kernel makefiles to handle
1210include file installation.  It is intended to be included alone, by
1211kernel Makefiles.  It uses similar variables to <bsd.inc.mk>.
1212Please see <bsd.kinc.mk> for more details, and keep the documentation
1213in that file up to date.
1214
1215=-=-=-=-=   bsd.syscall.mk =-=-=-=-=
1216
1217The include file <bsd.syscall.mk> contains the logic to create syscall
1218files for various emulations. It includes <bsd.kinc.mk> to handle the
1219rest of the targets.
1220
1221=-=-=-=-=   bsd.lib.mk   =-=-=-=-=
1222
1223The include file <bsd.lib.mk> has support for building libraries.  It has
1224the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1225includes, install, lint, and tags.  Additionally, it has a checkver target
1226which checks for installed shared object libraries whose version is greater
1227that the version of the source. It has a limited number of suffixes,
1228consistent with the current needs of the BSD tree.  <bsd.lib.mk> includes
1229<bsd.shlib.mk> to get shared library parameters.
1230
1231It sets/uses the following variables:
1232
1233LIB		The name of the library to build.
1234
1235LIBDIR		Target directory for libraries.
1236
1237MKARZERO	Normally, ar(1) sets the timestamps, uid, gid and
1238		permissions in files inside its archives to those of
1239		the file it was fed. This leads to non-reproducible
1240		builds. If MKARZERO is set to "yes" (default is the
1241		same as MKREPRO, or "no" if MKREPRO is not defined),
1242		then the "D" flag is passed to ar, causing the
1243		timestamp, uid and gid to be zeroed and the file
1244		permissions to be set to 644. This allows .a files
1245		from different builds to be bit identical.
1246
1247SHLIBINSTALLDIR	Target directory for shared libraries if ${USE_SHLIBDIR}
1248		is not "no".
1249
1250SHLIB_MAJOR
1251SHLIB_MINOR
1252SHLIB_TEENY	Major, minor, and teeny version numbers of shared library
1253
1254USE_SHLIBDIR	If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
1255		as the path to install shared libraries to.
1256		USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
1257		Default: no
1258
1259LIBISMODULE	If not "no", install as ${LIB}.so (without the "lib" prefix),
1260		and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
1261		MKPROFILE=no MKSTATICLIB=no".
1262		Default: no
1263
1264LIBISPRIVATE	If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
1265		MKPROFILE=no", and don't install the (.a) library.
1266		This is useful for "build only" helper libraries.
1267		Default: no
1268
1269LIBISCXX	If not "no", Use ${CXX} instead of ${CC} to link
1270		shared libraries.
1271		This is useful for C++ libraries.
1272		Default: no
1273
1274LINTLIBDIR	Target directory for lint libraries.
1275
1276LIBGRP		Library group.
1277
1278LIBOWN		Library owner.
1279
1280LIBMODE		Library mode.
1281
1282LDADD		Additional loader objects.
1283
1284MAN		The manual pages to be installed (use a .1 - .9 suffix).
1285
1286NOCHECKVER_<library>
1287NOCHECKVER	If set, disables checking for installed shared object
1288		libraries with versions greater than the source.  A
1289		particular library name, without the "lib" prefix, may
1290		be appended to the variable name to disable the check for
1291		only that library.
1292
1293SRCS		List of source files to build the library.  Suffix types
1294		.s, .c, and .f are supported.  Note, .s files are preferred
1295		to .c files of the same name.  (This is not the default for
1296		versions of make.)
1297
1298LIBDPLIBS	A list of the tuples:
1299			libname  path-to-srcdir-of-libname
1300
1301		For each tuple;
1302		     *	LIBDO.libname contains the .OBJDIR of the library
1303			`libname', and if it is not set it is determined
1304			from the srcdir and added to MAKEOVERRIDES (the
1305			latter is to allow for build time optimization).
1306		     *	LDADD gets  -L${LIBDO.libname} -llibname    added.
1307		     *	DPADD gets  ${LIBDO.libname}/liblibname.so  or
1308				    ${LIBDO.libname}/liblibname.a   added.
1309
1310		The special value "_external" for LIBDO.lib makes the
1311		build system to assume the library comes from outside
1312		of the NetBSD source tree and only causes -llibname
1313		to be added to LDADD.
1314
1315		This variable may be used for individual libraries, as
1316		well as in parent directories to cache common libraries
1317		as a build-time optimization.
1318
1319The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1320if it exists, as well as the include file <bsd.man.mk>.
1321
1322It has rules for building profiled objects; profiled libraries are
1323built by default.
1324
1325Libraries are ranlib'd when made.
1326
1327
1328=-=-=-=-=   bsd.links.mk   =-=-=-=-=
1329
1330The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1331and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1332
1333LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1334is used. The defaults may be modified by other bsd.*.mk files which
1335include bsd.links.mk.  In the future, these variables may be replaced
1336by a method for explicitly recording hard links in a metadata log.
1337
1338LINKS		The list of hard links, consisting of pairs of paths:
1339			source-file target-file
1340		${DESTDIR} is prepended to both paths before linking.
1341		For example, to link /bin/test and /bin/[, use:
1342			LINKS=/bin/test /bin/[
1343
1344CONFIGLINKS	Similar semantics to LINKS, except that the links
1345		are installed by the `configinstall' target,
1346		not the `install' target.
1347
1348SYMLINKS	The list of symbolic links, consisting of pairs of paths:
1349			source-file target-file
1350		${DESTDIR} is only prepended to target-file before linking.
1351		For example, to symlink /usr/bin/tar to /bin/tar resulting
1352		in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1353			SYMLINKS=/bin/tar /usr/bin/tar
1354
1355CONFIGSYMLINKS	Similar semantics to SYMLINKS, except that the symbolic links
1356		are installed by the `configinstall' target,
1357		not the `install' target.
1358
1359LINKSOWN	Link owner.  [${BINOWN}]
1360
1361LINKSGRP	Link group.  [${BINGRP}]
1362
1363LINKSMODE	Link mode.  [${NONBINMODE}]
1364
1365LINKSOWN_<fn>	Link owner of the specific file <fn>.
1366
1367LINKSGRP_<fn>	Link group of the specific file <fn>.
1368
1369LINKSMODE_<fn>	Link mode of the specific file <fn>.
1370
1371
1372=-=-=-=-=   bsd.man.mk   =-=-=-=-=
1373
1374The include file <bsd.man.mk> handles installing manual pages and their
1375links.
1376
1377It has a three targets:
1378
1379	catinstall:
1380		Install the preformatted manual pages and their links.
1381	htmlinstall:
1382		Install the HTML manual pages and their links.
1383	maninstall:
1384		Install the manual page sources and their links.
1385
1386It sets/uses the following variables:
1387
1388MANDIR		Base path for manual installation.
1389
1390MANGRP		Manual group.
1391
1392MANOWN		Manual owner.
1393
1394MANMODE		Manual mode.
1395
1396MANSUBDIR	Subdirectory under the manual page section, i.e. "/vax"
1397		or "/tahoe" for machine specific manual pages.
1398
1399MAN		The manual pages to be installed (use a .1 - .9 suffix).
1400
1401MLINKS		List of manual page links (using a .1 - .9 suffix).  The
1402		linked-to file must come first, the linked file second,
1403		and there may be multiple pairs.
1404
1405The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1406it exists.
1407
1408
1409=-=-=-=-=   bsd.obj.mk   =-=-=-=-=
1410
1411The include file <bsd.obj.mk> defines targets related to the creation
1412and use of separated object and source directories.
1413
1414If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1415${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1416it exists.  Otherwise make(1) looks for the existence of a
1417subdirectory (or a symlink to a directory) of the source directory
1418into which built targets should be placed.  If an environment variable
1419named MAKEOBJDIR is set, make(1) uses its value as the name of the
1420object directory; failing that, make first looks for a subdirectory
1421named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1422
1423Object directories are not created automatically by make(1) if they
1424don't exist; you need to run a separate "make obj".  (This will happen
1425during a top-level build if "MKOBJDIRS" is set to a value other than
1426"no").  When the source directory is a subdirectory of ${BSDSRCDIR} --
1427and this is determined by a simple string prefix comparison -- object
1428directories are created in a separate object directory tree, and a
1429symlink to the object directory in that tree is created in the source
1430directory; otherwise, "make obj" assumes that you're not in the main
1431source tree and that it's not safe to use a separate object tree.
1432
1433Several variables used by <bsd.obj.mk> control exactly what
1434directories and links get created during a "make obj":
1435
1436MAKEOBJDIR	If set, this is the component name of the object
1437		directory.
1438
1439OBJMACHINE	If this is set but MAKEOBJDIR is not set, creates
1440		object directories or links named "obj.${MACHINE}";
1441		otherwise, just creates ones named "obj".
1442
1443USR_OBJMACHINE  If set, and the current directory is a subdirectory of
1444		${BSDSRCDIR}, create object directory in the
1445		corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1446		otherwise, create it in the corresponding subdirectory
1447		of ${BSDOBJDIR}
1448
1449BUILDID		If set, the contents of this variable are appended
1450		to the object directory name.  If OBJMACHINE is also
1451		set, ".${BUILDID}" is added after ".${MACHINE}".
1452
1453
1454=-=-=-=-=   bsd.prog.mk   =-=-=-=-=
1455
1456The include file <bsd.prog.mk> handles building programs from one or
1457more source files, along with their manual pages.  It has a limited number
1458of suffixes, consistent with the current needs of the BSD tree.
1459<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1460
1461It has eight targets:
1462
1463	all:
1464		build the program and its manual page.  This also
1465		creates a GDB initialization file (.gdbinit) in
1466		the objdir.  The .gdbinit file sets the shared library
1467		prefix to ${DESTDIR} to facilitate cross-debugging.
1468	clean:
1469		remove the program, any object files and the files a.out,
1470		Errs, errs, mklog, and ${PROG}.core.
1471	cleandir:
1472		remove all of the files removed by the target clean, as
1473		well as .depend, tags, and any manual pages.
1474		`distclean' is a synonym for `cleandir'.
1475	depend:
1476		make the dependencies for the source files, and store
1477		them in the file .depend.
1478	includes:
1479		install any header files.
1480	install:
1481		install the program and its manual pages; if the Makefile
1482		does not itself define the target install, the targets
1483		beforeinstall and afterinstall may also be used to cause
1484		actions immediately before and after the install target
1485		is executed.
1486	lint:
1487		run lint on the source files
1488	tags:
1489		create a tags file for the source files.
1490
1491It sets/uses the following variables:
1492
1493BINGRP		Binary group.
1494
1495BINOWN		Binary owner.
1496
1497BINMODE		Binary mode.
1498
1499CLEANDIRFILES	Additional files to remove for the cleandir target.
1500
1501CLEANFILES	Additional files to remove for the clean and cleandir targets.
1502
1503CONFIGOPTS	Additional flags to config(1) when building kernels.
1504
1505COPTS		Additional flags to the compiler when creating C objects.
1506
1507COPTS.<fn>	Additional flags to the compiler when creating the
1508		C objects for <fn>.
1509		For <fn>.[ly], "<fn>.c" must be used.
1510
1511CPUFLAGS	Additional flags to the compiler/assembler to select
1512		CPU instruction set options, CPU tuning options, etc.
1513
1514CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1515		For <fn>.[ly], "<fn>.c" must be used.
1516
1517CPPFLAGS	Additional flags to the C pre-processor.
1518
1519CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1520		For <fn>.[ly], "<fn>.c" must be used.
1521
1522GDBINIT		List of GDB initialization files to add to "source"
1523		directives in the .gdbinit file that is created in the
1524		objdir.
1525
1526LDADD		Additional loader objects.  Usually used for libraries.
1527		For example, to load with the compatibility and utility
1528		libraries, use:
1529
1530			LDADD+=-lutil -lcompat
1531
1532LDFLAGS		Additional linker flags (passed to ${CC} during link).
1533
1534LINKS		See <bsd.links.mk>
1535
1536OBJCOPTS	Additional flags to the compiler when creating ObjC objects.
1537
1538OBJCOPTS.<fn>	Additional flags to the compiler when creating the
1539		ObjC objects for <fn>.
1540		For <fn>.[ly], "<fn>.c" must be used.
1541
1542SYMLINKS	See <bsd.links.mk>
1543
1544MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1545		defined, "MAN=${PROG}.1" is assumed.
1546
1547PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1548		time, with the value of this variable as args to paxctl(1).
1549
1550PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1551
1552PROG		The name of the program to build.  If not supplied, nothing
1553		is built.
1554
1555PROG_CXX	If defined, the name of the program to build.  Also
1556		causes <bsd.prog.mk> to link the program with the C++
1557		compiler rather than the C compiler.  PROG_CXX overrides
1558		the value of PROG if PROG is also set.
1559
1560PROGNAME	The name that the above program will be installed as, if
1561		different from ${PROG}.
1562
1563SRCS		List of source files to build the program.  If SRCS is not
1564		defined, it's assumed to be ${PROG}.c.

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

1875
1876X11FLAGS.EXTENSION	Equivalent to X11's EXT_DEFINES.
1877
1878X11FLAGS.LOADABLE	Equivalent to X11's LOADABLE.
1879
1880X11FLAGS.OS_DEFINES	Equivalent to X11's OS_DEFINES.
1881
1882X11FLAGS.SERVER		Equivalent to X11's ServerDefines.
1883
1884X11FLAGS.THREADLIB	Equivalent to X11's THREADS_DEFINES for libraries.
1885

1887
1888X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1889
1890X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1891
1892X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1893
1894It uses the following variables:
1895
1896APPDEFS			List of app-default files to install.
1897
1898CPPSCRIPTS		List of files/scripts to run through cpp(1)
1899			and then ${X11TOOL_UNXCOMM}.  The source files
1900			have a `.cpp' suffix, the generated files do not.
1901
1902CPPSCRIPTFLAGS		Additional flags to cpp(1) when building CPPSCRIPTS.
1903
1904CPPSCRIPTFLAGS_<fn>	Additional flags to cpp(1) when building CPPSCRIPT <fn>.

1907=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
1908
1909The following files are described here for completion, but they are not
1910supposed to be included directly from other Makefiles; they are used
1911internally by other system files.
1912
1913=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1914
1915The include file <bsd.sys.mk> is used by other system mk files and
1916it is not intended to be included standalone. It contains rules and
1917system build variables. It requires bsd.own.mk to be included first.
1918It contains overrides that are used when building the NetBSD source tree.
1919
