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

152		during build.
153		Default: no
154

269MKKYUA		If "no", don't build Kyua nor its dependent library Lutok.
270		Note that setting this to "no" does not disable the build of
271		the NetBSD test suite itself; the build of the tests is
272		controlled by the MKATF knob.

434		Default: yes on platforms that support it.
435
436MKSTRIPSYM	If "yes", strip all local symbols from shared libraries;
437		the affect is equivalent to -x option of ld(1). If "no",
438		strip only temporary local symbols; the affect is equivalent
439		to -X option of ld(1). Keeping non-temporary local symbols
440		such as static function names is useful on using DTrace for
441		userland libraries and getting a backtrace from a rump kernel
442		loading shared libraries.
443		Default: yes
444
445MKTEGRAFIRMWARE	If "no", install the /libdata/firmware/nvidia directory,
446		which is necessary for the NVIDIA Tegra XHCI driver.

461		the owner/group/mode should be.  This allows a
462		non-root "make install".
463		Default: no
464
465MKUPDATE 	If not "no", 'make install' only installs targets that are
466		more recently modified in the source directories that their
467		installed counterparts.
468		Default: no
469
470MKX11		If not "no", 'make build' also descends into 
471		src/external/mit/xorg to cross-build X11 and automatically
472		enables creation of X sets.
473		Default: no
474
475MKX11FONTS	If not "no", do not build or install the X fonts.  The xfont
476		set is still created but will be empty.
477		Default: yes
478
479MKX11MOTIF:	If "yes", build the native X11 libGLw with Motif stubs.  If
480		Motif is not installed in the default location /usr/pkg, the

493
494MKRUMP		If "no", do not build and install rump related headers,
495		libraries, and programs.
496		Default: yes
497
498USE_HESIOD	If "no", disables building Hesiod support into
499		various system utilities/libraries that support it.
500		If ${MKHESIOD} is "no", USE_HESIOD will also be
501		forced to "no".
502
503USE_INET6	If "no", disables building INET6 (IPv6) support into
504		various system utilities/libraries that support it.
505		If ${MKINET6} is "no", USE_INET6 will also be
506		forced to "no".
507
508USE_JEMALLOC	If "no", disables building the "jemalloc" allocator
509		designed for improved performance with threaded
510		applications.  The "phkmalloc" allocator as used up
511		before NetBSD-5.0 will be substituted.
512
513USE_KERBEROS	If "no", disables building Kerberos v5
514		support into various system utilities/libraries that
515		support it.  If ${MKKERBEROS} is "no", USE_KERBEROS

531
532USE_SSP		If "no", disables GCC stack protection code, which
533		detects stack overflows and aborts the program. The
534		stack protection code imposes a performance penalty
535		of about 5%.
536		Default: "no", unless "USE_FORT" is set to "yes"
537
538NOSSP		Don't compile with stack protector during build.
539		It is set internally for standalone programs.
540
541USE_FORT 	If "yes" turns on substitute wrappers for commonly used
542		functions that do not do bounds checking regularly, but
543		they could in some cases by using the gcc
544		__builtin_object_size() function to determine the buffer
545		size where it is known and detect buffer overflows.
546		These substitute functions are in /usr/include/ssp.
547		Default: depends on the part of the source tree
548
549NOFORT		Don't compile with substitute wrappers during build.
550		It is set internally for standalone programs.
551
552USE_YP		If "no", disables building YP (NIS) support into
553		various system utilities/libraries that support it.
554		If ${MKYP} is "no", USE_YP will also be forced to "no".
555
556USE_PIGZGZIP	If "no", use the host "gzip" program to compress things.
557		Otherwise, build tools/pigz, set TOOL_GZIP=${TOOL_PIGZ},
558		and use nbpigz to compress things.
559		Default: "no".

565CXXFLAGS.lib<lib>
566COPTS.<prog>
567OBJCCOPTS.<prog>
568LDADD.<prog>
569CPPFLAGS.<prog>
570CXXFLAGS.<prog>	These provide a way to specify additions to the associated
571		variables in a way that applies only to a particular library
572		or program.  <lib> corresponds to the LIB variable set in
573		the library's makefile.  <prog> corresponds to either PROG
574		or PROG_CXX (if set).  For example, if COPTS.libcrypto is
575		set to "-g", "-g" will be added to COPTS only when compiling
576		the crypto library.
577
578The active compiler is selected using the following variables:
579AVAILABLE_COMPILER
580		List of available compiler suites.  Processed in order
581		for selecting the active compiler for each frontend.
582HAVE_PCC	If defined, PCC is present and enabled.
583HAVE_LLVM	If defined, LLVM/Clang is present and enabled.
584UNSUPPORTED_COMPILER.xxx
585		If defined, the support for compiler "xxx" is disabled.
586
587For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist:
588ACTIVE_CC	Active compile suite for the CC frontend.
589SUPPORTED_CC	Compile suite with support for the CC frontend.
590TOOL_CC.xxx	Path to the CC frontend for compiler "xxx"
591
592=-=-=-=-=   sys.mk   =-=-=-=-=
593
594The include file <sys.mk> has the default rules for all makes, in the BSD
595environment or otherwise.  You probably don't want to touch this file.
596
597=-=-=-=-=   bsd.own.mk   =-=-=-=-=
598
599The include file <bsd.own.mk> contains source tree configuration parameters,
600such as the owners, groups, etc. for both manual pages and binaries, and
601a few global "feature configuration" parameters.
602
603It has no targets.
604
605To get system-specific configuration parameters, <bsd.own.mk> will try to
606include the file specified by the "MAKECONF" variable.  If MAKECONF is not
607set, or no such file exists, the system make configuration file, /etc/mk.conf
608is included.  These files may define any of the variables described below.
609
610<bsd.own.mk> sets the following variables, if they are not already defined
611(defaults are in brackets):
612
613NETBSDSRCDIR	Top of the NetBSD source tree.
614		If _SRC_TOP_ != "", that will be used as the default,
615		otherwise BSDSRCDIR will be used as the default.
616		Various makefiles within the NetBSD source tree will
617		use this to reference the top level of the source tree.
618
619_SRC_TOP_	Top of the system source tree, as determined by <bsd.own.mk>
620		based on the presence of tools/ and build.sh.  This variable
621		is "internal" to <bsd.own.mk>, although its value is only
622		determined once and then propagated to all sub-makes.
623
624_NETBSD_VERSION_DEPENDS
625		A list of files which contain information about
626		the version of the NetBSD being built.  This is
627		defined only if the current directory appears
628		to be inside a NetBSD source tree.  The list of
629		files includes ${NETBSDSRCDIR}/sys/sys/param.h
630		(which contains the kernel version number),
631		${NETBSDSRCDIR}/sys/conf/newvers.sh and
632		${NETBSDSRCDIR}/sys/conf/osrelease.sh (which
633		interpret the information in sys/sys/param.h), and
634		${_SRC_TOP_OBJ_}/params (which is an optional file,
635		created by "make build" in ${_SRC_TOP_}/Makefile,
636		containing all the variables that may influence the
637		build).
638
639		Targets that depend on the NetBSD version, or on
640		variables defined at build time, can declare a
641		dependency on ${_NETBSD_VERSION_DEPENDS}, like this:
642
643			version.c: ${_NETBSD_VERSION_DEPENDS}
644				commands to create version.c
645
646BSDSRCDIR	The real path to the system sources, so that 'make obj'
647		will work correctly.  [/usr/src]

729
730X11USRLIBDIR	X11 library directory.  [${X11ROOTDIR}/lib]
731
732STRIPFLAG	The flag passed to the install program to cause the binary
733		to be stripped.  This is to be used when building your
734		own install script so that the entire system can be made
735		stripped/not-stripped using a single knob.  []
736
737COPY		The flag passed to the install program to cause the binary
738		to be copied rather than moved.  This is to be used when
739		building our own install script so that the entire system
740		can either be installed with copies, or with moves using
741		a single knob.  [-c]
742
743MAKEDIRTARGETENV
744		Environment variables passed to the child make process
745		invoked by MAKEDIRTARGET.
746
747MAKEDIRTARGET dir target [params]
748		Runs "cd $${dir} && ${MAKE} [params] $${target}",
749		displaying a "pretty" message whilst doing so.
750
751RELEASEMACHINEDIR
752		Subdirectory used below RELEASEDIR when building
753		a release.  [${MACHINE}]
754
755RELEASEMACHINE	Subdirectory or path component used for the following
756		paths:
757			distrib/${RELEASEMACHINE}
758			distrib/notes/${RELEASEMACHINE}
759			etc/etc.${RELEASEMACHINE}
760		Used when building a release.  [${MACHINE}]
761
762Additionally, the following variables may be set by <bsd.own.mk> or in a
763make configuration file to modify the behavior of the system build
764process (default values are in brackets along with comments, if set by
765<bsd.own.mk>):
766
767USETOOLS	Indicates whether the tools specified by ${TOOLDIR} should
768		be used as part of a build in progress.
769		Supported values:
770
771		yes	Use the tools from TOOLDIR.
772			Must be set to this if cross-compiling.
773
774		no	Do not use the tools from TOOLDIR, but refuse to
775			build native compilation tool components that are
776			version-specific for that tool.
777
778		never	Do not use the tools from TOOLDIR, even when
779			building native tool components.  This is similar to
780			the traditional NetBSD build method, but does not
781			verify that the compilation tools in use are
782			up-to-date enough in order to build the tree
783			successfully.  This may cause build or runtime
784			problems when building the whole NetBSD source tree.
785
786		Default: "yes" if building all or part of a whole NetBSD
787		source tree (detected automatically); "no" otherwise
788		(to preserve traditional semantics of the <bsd.*.mk>
789		make(1) include files).
790
791OBJECT_FMT	Object file format.  [set to "ELF" on architectures that
792		use ELF -- currently all architectures].
793
794TOOLCHAIN_MISSING
795		If not "no", this indicates that the platform being built
796		does not have a working in-tree toolchain.  If the
797		${MACHINE_ARCH} in question falls into this category,
798		TOOLCHAIN_MISSING is conditionally assigned the value "yes".
799		Otherwise, the variable is unconditionally assigned the
800		value "no".
801		If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are
802		unconditionally assigned the value "no".
803
804EXTERNAL_TOOLCHAIN
805		This variable is not directly set by <bsd.own.mk>, but
806		including <bsd.own.mk> is the canonical way to gain
807		access to this variable.  The variable should be defined
808		either in the user's environment or in the user's mk.conf
809		file.  If defined, this variable indicates the root of
810		an external toolchain which will be used to build the
811		tree.  For example, if a platform is a ${TOOLCHAIN_MISSING}
812		platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
813		cross-compile framework.
814
815		If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
816		assigned the value "no", since the external version of the
817		compiler may not be able to build the library components of
818		the in-tree compiler.
819
820		This variable should be used in conjunction with an appropiate
821		HAVE_GCC or HAVE_LLVM setting to control the compiler flags.
822
823		NOTE: This variable is not yet used in as many places as
824		it should be.  Expect the exact semantics of this variable
825		to change in the short term as parts of the cross-compile
826		framework continue to be cleaned up.
827
828The following variables are defined to commands to perform the
829appropriate operation, with the default in [brackets].  Note that
830the defaults change if USETOOLS == "yes":
831
832TOOL_AMIGAAOUT2BB	aout to Amiga bootblock converter.  [amiga-aout2bb]

982
983<bsd.own.mk> is generally useful when building your own Makefiles so that
984they use the same default owners etc. as the rest of the tree.
985
986
987=-=-=-=-=   bsd.clean.mk   =-=-=-=-=
988
989The include file <bsd.clean.mk> defines the clean and cleandir
990targets.  It uses the following variables:
991
992CLEANFILES	Files to remove for both the clean and cleandir targets.
993
994CLEANDIRFILES	Files to remove for the cleandir target, but not for
995		the clean target.
996
997MKCLEANSRC	Controls whether or not the clean and cleandir targets
998		will delete files from both the object directory,
999		${.OBJDIR}, and the source directory, ${.CURDIR}.
1000
1001		If MKCLEANSRC is set to "no", then the file names in
1002		CLEANFILES or CLEANDIRFILES are interpreted relative
1003		to the object directory, ${.OBJDIR}.  This is the
1004		traditional behaviour.
1005
1006		If MKCLEANSRC is set to "yes", then the file deletion
1007		is performed relative to both the object directory,
1008		${.OBJDIR}, and the source directory, ${.CURDIR}.  (This
1009		has no effect if ${.OBJDIR} is the same as ${.CURDIR}.)
1010		Deleting files from ${.CURDIR} is intended to remove
1011		stray output files that had been left in the source
1012		directory by an earlier build that did not use object
1013		directories.
1014
1015		The default is MKCLEANSRC=yes.  If you always build with
1016		separate object directories, and you are sure that there
1017		are no stray files in the source directories, then you
1018		may set MKCLEANSRC=no to save some time.
1019
1020MKCLEANVERIFY	Controls whether or not the clean and cleandir targets
1021		will verify that files have been deleted.
1022
1023		If MKCLEANVERIFY is set to "no", then the files will
1024		be deleted using a "rm -f" command, and its success or
1025		failure will be ignored.
1026
1027		If MKCLEANVERIFY is set to "yes", then the success of
1028		the "rm -f" command will be verified using an "ls"
1029		command.
1030
1031		The default is MKCLEANVERIFY=yes.  If you are sure that
1032		there will be no problems caused by file permissions,
1033		read-only file systems, or the like, then you may set
1034		MKCLEANVERIFY=no to save some time.
1035
1036To use the clean and cleandir targets defined in <bsd.clean.mk>, other
1037Makefiles or bsd.*.mk files should append file names to the CLEANFILES
1038or CLEANDIRFILES variables.  For example:
1039
1040	    CLEANFILES+= a.out
1041	    CLEANDIRFILES+= .depend
1042
1043	    .include <bsd.clean.mk>
1044
1045The files listed in CLEANFILES and CLEANDIRFILES must not be
1046directories, because the potential risk from running "rm -rf" commands
1047in bsd.clean.mk is considered too great.  If you want to recursively
1048delete a directory as part of "make clean" or "make cleandir" then you
1049need to provide your own target.
1050
1051=-=-=-=-=   bsd.dep.mk   =-=-=-=-=
1052
1053The include file <bsd.dep.mk> contains the default targets for building
1054.depend files.  It creates .d files from entries in SRCS and DPSRCS
1055that are C, C++, or Objective C source files, and builds .depend from the
1056.d files.  All other files in SRCS and all of DPSRCS will be used as
1057dependencies for the .d files.  In order for this to function correctly,
1058it should be .included after all other .mk files and directives that may
1059modify SRCS or DPSRCS.  It uses the following variables:
1060
1061SRCS		List of source files to build the program.
1062
1063DPSRCS		List of source files which are needed for generating
1064		dependencies, but are not needed in ${SRCS}.

1068
1069The include file <bsd.files.mk> handles the FILES variables and is included
1070from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
1071
1072FILES		The list of files to install.
1073
1074CONFIGFILES	Similar semantics to FILES, except that the files
1075		are installed by the `configinstall' target,
1076		not the `install' target.
1077		The FILES* variables documented below also apply.
1078
1079FILESOWN	File owner.  [${BINOWN}]
1080
1081FILESGRP	File group.  [${BINGRP}]
1082
1083FILESMODE	File mode.  [${NONBINMODE}]
1084
1085FILESDIR	The location to install the files.
1086
1087FILESNAME	Optional name to install each file as.
1088
1089FILESOWN_<fn>	File owner of the specific file <fn>.
1090
1091FILESGRP_<fn>	File group of the specific file <fn>.
1092
1093FILESMODE_<fn>	File mode of the specific file <fn>.
1094
1095FILESDIR_<fn>	The location to install the specific file <fn>.
1096
1097FILESNAME_<fn>	Optional name to install <fn> as.
1098
1099FILESBUILD	If this variable is defined, then its value will be
1100		used as the default for all FILESBUILD_<fn> variables.
1101		Otherwise, the default will be "no".
1102
1103FILESBUILD_<fn>	A value different from "no" will add the file to the list of
1104		targets to be built by `realall'.  Users of that variable
1105		should provide a target to build the file.
1106
1107
1108BUILDSYMLINKS	List of two word items:
1109			lnsrc lntgt
1110		For each lnsrc item, create a symlink named lntgt.
1111		The lntgt symlinks are removed by the cleandir target.
1112
1113UUDECODE_FILES	List of files which are stored as <file>.uue in the source
1114		tree. Each one will be decoded with ${TOOL_UUDECODE}.
1115		The source files have a `.uue' suffix, the generated files do
1116		not.
1117
1118UUDECODE_FILES_RENAME_<fn>
1119		Rename the output from the decode to the provided name.
1120		
1121		*NOTE: These files are simply decoded, with no install or other

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

1510CONFIGOPTS	Additional flags to config(1) when building kernels.
1511
1512COPTS		Additional flags to the compiler when creating C objects.
1513

1518CPUFLAGS	Additional flags to the compiler/assembler to select
1519		CPU instruction set options, CPU tuning options, etc.
1520
1521CPUFLAGS.<fn>	Additional flags to the compiler/assembler for <fn>.
1522		For <fn>.[ly], "<fn>.c" must be used.

1526CPPFLAGS.<fn>	Additional flags to the C pre-processor for <fn>.
1527		For <fn>.[ly], "<fn>.c" must be used.
1528
1529GDBINIT		List of GDB initialization files to add to "source"
1530		directives in the .gdbinit file that is created in the
1531		objdir.
1532
1533LDADD		Additional loader objects.  Usually used for libraries.
1534		For example, to load with the compatibility and utility
1535		libraries, use:
1536
1537			LDADD+=-lutil -lcompat
1538
1539LDFLAGS		Additional linker flags (passed to ${CC} during link).
1540
1541LINKS		See <bsd.links.mk>

1548
1549SYMLINKS	See <bsd.links.mk>
1550
1551MAN		Manual pages (should end in .1 - .9).  If no MAN variable is
1552		defined, "MAN=${PROG}.1" is assumed.
1553
1554PAXCTL_FLAGS	If defined, run paxctl(1) on the program binary after link
1555		time, with the value of this variable as args to paxctl(1).
1556
1557PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1558
1559PROG		The name of the program to build.  If not supplied, nothing
1560		is built.
1561
1562PROG_CXX	If defined, the name of the program to build.  Also
1563		causes <bsd.prog.mk> to link the program with the C++
1564		compiler rather than the C compiler.  PROG_CXX overrides
1565		the value of PROG if PROG is also set.
1566
1567PROGNAME	The name that the above program will be installed as, if
1568		different from ${PROG}.
1569

1571		defined, it's assumed to be ${PROG}.c.
1572
1573DPSRCS		List of source files which are needed for generating
1574		dependencies, but are not needed in ${SRCS}.
1575
1576DPADD		Additional dependencies for the program.  Usually used for
1577		libraries.  For example, to depend on the compatibility and
1578		utility libraries use:
1579

1733
1734SHAREDSTRINGS	If defined, a new .c.o rule is used that results in shared
1735		strings, using xstr(1). Note that this will not work with
1736		parallel makes.
1737
1738STRIPFLAG	The flag passed to the install program to cause the binary
1739		to be stripped.
1740
1741SUBDIR		A list of subdirectories that should be built as well.

1746		These are installed exactly like programs.
1747
1748SCRIPTSDIR	The location to install the scripts.  Each script can be
1749		installed to a separate path by setting SCRIPTSDIR_<script>.
1750
1751SCRIPTSNAME	The name that the above program will be installed as, if
1752		different from ${SCRIPTS}. These can be further specialized
1753		by setting SCRIPTSNAME_<script>.
1754
1755FILES		See description of <bsd.files.mk>.
1756
1757SHLINKDIR	Target directory for shared linker.  See description of
1758		<bsd.own.mk> for additional information about this variable.
1759

1761if it exists, as well as the include file <bsd.man.mk>.
1762
1763Some simple examples:
1764
1765To build foo from foo.c with a manual page foo.1, use:
1766
1767	PROG=	foo
1768
1769	.include <bsd.prog.mk>
1770
1771To build foo from foo.c with a manual page foo.2, add the line:
1772
1773	MAN=	foo.2
1774
1775If foo does not have a manual page at all, add the line:
1776
1777	MKMAN=	no
1778
1779If foo has multiple source files, add the line:
1780
1781	SRCS=	a.c b.c c.c d.c
1782
1783
1784=-=-=-=-=   bsd.rpc.mk   =-=-=-=-=
1785
1786The include file <bsd.rpc.mk> contains a makefile fragment used to
1787construct source files built by rpcgen.
1788
1789The following macros may be defined in makefiles which include
1790<bsd.rpc.mk> in order to control which files get built and how they
1791are to be built:
1792
1793RPC_INCS:	construct .h file from .x file
1794RPC_XDRFILES:	construct _xdr.c from .x file
1795		(for marshalling/unmarshalling data types)
1796RPC_SVCFILES:	construct _svc.c from .x file
1797		(server-side stubs)
1798RPC_SVCFLAGS:	Additional flags passed to builds of RPC_SVCFILES.
1799
1800RPC_XDIR:	Directory containing .x/.h files
1801
1802
1803=-=-=-=-=   bsd.shlib.mk   =-=-=-=-=
1804
1805The include file <bsd.shlib.mk> computes parameters for shared library
1806installation and use.  It defines no targets.  <bsd.own.mk> MUST be
1807included before <bsd.shlib.mk>.
1808
1809<bsd.own.mk> sets the following variables, if they are not already defined
1810(defaults are in brackets):
1811
1812SHLIBINSTALLDIR	If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1813		instead of ${LIBDIR} as the base path for shared library
1814		installation.  [/lib]
1815
1816SHLIBDIR	The path to USE_SHLIBDIR shared libraries to use when building
1817		a program.  [/lib for programs in /bin and /sbin, /usr/lib
1818		for all others.]
1819
1820_LIBSODIR	Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1821		otherwise set to ${LIBDIR}
1822
1823SHLINKINSTALLDIR Base path for shared linker.  [/libexec]
1824
1825SHLINKDIR	Path to use for shared linker when building a program.
1826		[/libexec for programs in /bin and /sbin, /usr/libexec for
1827		all others.]
1828
1829
1830=-=-=-=-=   bsd.subdir.mk   =-=-=-=-=
1831
1832The include file <bsd.subdir.mk> contains the default targets for building
1833subdirectories.  It has the same eight targets as <bsd.prog.mk>: all,
1834clean, cleandir, depend, includes, install, lint, and tags.  It uses the
1835following variables:
1836
1837NOSUBDIR	If this variable is defined, then the SUBDIR variable
1838		will be ignored and subdirectories will not be processed.
1839
1840SUBDIR		For all of the directories listed in ${SUBDIR}, the
1841		specified directory will be visited and the target made.
1842
1843		As a special case, the use of a token .WAIT as an
1844		entry in SUBDIR acts as a synchronization barrier
1845		when multiple make jobs are run; subdirs before the
1846		.WAIT must complete before any subdirs after .WAIT are
1847		started.  See make(1) for some caveats on use of .WAIT
1848		and other special sources.
1849
1850
1851=-=-=-=-=   bsd.x11.mk   =-=-=-=-=
1852
1853The include file <bsd.x11.mk> contains parameters and targets for
1854cross-building X11 from ${X11SRCDIR.<package>}.  It should be included
1855after the general Makefile contents but before the include files such as
1856<bsd.prog.mk> and <bsd.lib.mk>.
1857
1858It provides the following targets:
1859	.man.1 .man.3 .man.4 .man.5 .man.7:
1860		If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1861		these rules convert from X11's manual page source
1862		into an mdoc.old source file.
1863
1864It sets the following variables:
1865
1866BINDIR			Set to ${X11BINDIR}.
1867			To override, define after including <bsd.x11.mk>
1868
1869LIBDIR			Set to ${X11USRLIBDIR}.
1870			To override, define after including <bsd.x11.mk>
1871
1872MANDIR			Set to ${X11MANDIR}.
1873			To override, define after including <bsd.x11.mk>
1874

1895X11FLAGS.VERSION	cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION.
1896
1897X11FLAGS.DIX		Equivalent to X11's DIX_DEFINES.
1898
1899X11TOOL_UNXCOMM		Commandline to convert `XCOMM' comments to `#'
1900
1901It uses the following variables:
1902
1903APPDEFS			List of app-default files to install.
1904
1905CPPSCRIPTS		List of files/scripts to run through cpp(1)
1906			and then ${X11TOOL_UNXCOMM}.  The source files

1915
1916The following files are described here for completion, but they are not
1917supposed to be included directly from other Makefiles; they are used
1918internally by other system files.
1919
1920=-=-=-=-=   bsd.sys.mk   =-=-=-=-=
1921
1922The include file <bsd.sys.mk> is used by other system mk files and
1923it is not intended to be included standalone. It contains rules and
1924system build variables. It requires bsd.own.mk to be included first.
1925It contains overrides that are used when building the NetBSD source tree.
1926
1927The following variables control how various files are compiled/built.
