4 This is the README file for the make "include" files for the NetBSD
5 source tree. The files are installed in /usr/share/mk, and are,
6 by convention, named with the suffix ".mk".
8 Note, this file is not intended to replace reading through the .mk
9 files for anything tricky.
11 =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
13 RANDOM THINGS WORTH KNOWING:
15 The files are simply C-style #include files, and pretty much behave like
16 you'd expect. The syntax is slightly different in that a single '.' is
17 used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
19 One difference that will save you lots of debugging time is that inclusion
20 of the file is normally done at the *end* of the Makefile. The reason for
21 this is because .mk files often modify variables and behavior based on the
22 values of variables set in the Makefile. To make this work, remember that
23 the FIRST target found is the target that is used, i.e. if the Makefile has:
30 the command "make a" will echo "a". To make things confusing, the SECOND
31 variable assignment is the overriding one, i.e. if the Makefile has:
39 the command "make b" will echo "bar". This is for compatibility with the
40 way the V7 make behaved.
42 It's fairly difficult to make the BSD .mk files work when you're building
43 multiple programs in a single directory. It's a lot easier to split up the
44 programs than to deal with the problem. Most of the agony comes from making
45 the "obj" directory stuff work right, not because we switched to a new version
46 of make. So, don't get mad at us, figure out a better way to handle multiple
47 architectures so we can quit using the symbolic link stuff. (Imake doesn't
50 The file .depend in the source directory is expected to contain dependencies
51 for the source files. This file is read automatically by make after reading
54 The variable DESTDIR works as before. It's not set anywhere but will change
55 the tree where the file gets installed.
57 The profiled libraries are no longer built in a different directory than
58 the regular libraries. A new suffix, ".po", is used to denote a profiled
59 object, and ".so" denotes a shared (position-independent) object.
61 There are various make variables used during the build.
63 Many variables support a (case sensitive) value of "no" or "yes",
64 and are tested with ${VAR} == "no" and ${VAR} != "no" .
67 The basic rule for the variable naming scheme is as follows:
69 HOST_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.
73 MKxxx Can be set to "no" to disable functionality, or
75 Usually defaults to "yes", although some variables
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
85 NOxxx 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>
92 TOOL_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.
97 The following variables that control how things are made/installed that
98 are not set by default. These should not be set by Makefiles; they're for
99 the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5))
100 or on the make(1) command line:
102 BUILD 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.
107 MAKEVERBOSE Control how "verbose" the standard make(1) rules are.
110 0 Minimal output ("quiet")
111 1 Describe what is occurring
112 2 Describe what is occurring and echo the actual command

313 the owner/group/mode should be. This allows a
314 non-root "make install".
317 MKUPDATE If not "no", 'make install' only installs targets that are
318 more recently modified in the source directories that their
319 installed counterparts.
322 MKX11 If not "no", depending on the value of ${X11FLAVOUR},
323 'make build' also descends into either src/x11 (XFree86) or
324 src/external/mit/xorg (modular Xorg) to cross-build X11 and
325 automatically enables creation of X sets.
328 MKX11FONTS If not "no", if ${X11FLAVOUR} is "Xorg", do not build or

343 various system utilities/libraries that support it.
344 If ${MKINET6} is "no", USE_INET6 will also be
347 USE_JEMALLOC If "no", disables building the "jemalloc" allocator
348 designed for improved performance with threaded
349 applications. The "phkmalloc" allocator as used up
350 before NetBSD-5.0 will be substituted.
352 USE_KERBEROS If "no", disables building Kerberos v5
353 support into various system utilities/libraries that
354 support it. If ${MKKERBEROS} is "no", USE_KERBEROS
355 will also be forced to "no".
357 USE_LDAP If "no", disables building LDAP support into various
358 system utilities/libraries that support it.
359 If ${MKLDAP} is "no", USE_LDAP will also be forced to "no".
361 USE_PAM If "no", disables building PAM authentication support
362 into various system utilities/libraries that support it.
363 If ${MKPAM} is "no", USE_PAM will also be forced to "no".
365 USE_SKEY If "no", disables building S/key authentication
366 support into various system utilities/libraries that
367 support it. If ${MKSKEY} is "no", USE_SKEY will
368 also be forced to "no".
371 USE_SSP If "no", disables GCC stack protection code, which
372 detects stack overflows and aborts the program. This
373 imposes some performance penalty.
376 USE_FORT If "yes" turns on substitute wrappers for commonly used
377 functions that do not do bounds checking regularly, but
378 they could in some cases by using the gcc
379 __builtin_object_size() function to determine the buffer
380 size where it is known and detect buffer overflows.
381 These substitute functions are in /usr/include/ssp.
384 USE_YP If "no", disables building YP (NIS) support into
385 various system utilities/libraries that support it.
386 If ${MKYP} is "no", USE_YP will also be forced to "no".
388 X11FLAVOUR Set to "Xorg" or "XFree86", depending on whether to build
389 XFree86 or modular Xorg. Only matters if MKX11!=no.
390 Default: "Xorg" on amd64, i386, macppc, shark and sparc64,
391 "XFree86" on everything else.
402 CXXFLAGS.<prog> These provide a way to specify additions to the associated
403 variables in a way that applies only to a particular library
404 or program. <lib> corresponds to the LIB variable set in
405 the library's makefile. <prog> corresponds to either PROG
406 or PROG_CXX (if set). For example, if COPTS.libcrypto is
407 set to "-g", "-g" will be added to COPTS only when compiling
410 =-=-=-=-= sys.mk =-=-=-=-=
412 The include file <sys.mk> has the default rules for all makes, in the BSD
413 environment or otherwise. You probably don't want to touch this file.
415 =-=-=-=-= bsd.own.mk =-=-=-=-=
417 The include file <bsd.own.mk> contains source tree configuration parameters,
418 such as the owners, groups, etc. for both manual pages and binaries, and
419 a few global "feature configuration" parameters.
423 To get system-specific configuration parameters, <bsd.own.mk> will try to
424 include the file specified by the "MAKECONF" variable. If MAKECONF is not
425 set, or no such file exists, the system make configuration file, /etc/mk.conf
426 is included. These files may define any of the variables described below.
428 <bsd.own.mk> sets the following variables, if they are not already defined
429 (defaults are in brackets):
431 NETBSDSRCDIR Top of the NetBSD source tree.
432 If _SRC_TOP_ != "", that will be used as the default,
433 otherwise BSDSRCDIR will be used as the default.
434 Various makefiles within the NetBSD source tree will
435 use this to reference the top level of the source tree.
437 _SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk>
438 based on the presence of tools/ and build.sh. This variable
439 is "internal" to <bsd.own.mk>, although its value is only
440 determined once and then propagated to all sub-makes.
442 BSDSRCDIR The real path to the system sources, so that 'make obj'
443 will work correctly. [/usr/src]
445 BSDOBJDIR The real path to the system 'obj' tree, so that 'make obj'

527 X11USRLIBDIR X11 library directory. [${X11ROOTDIR}/lib]
529 STRIPFLAG The flag passed to the install program to cause the binary
530 to be stripped. This is to be used when building your
531 own install script so that the entire system can be made
532 stripped/not-stripped using a single knob. []
534 COPY The flag passed to the install program to cause the binary
535 to be copied rather than moved. This is to be used when
536 building our own install script so that the entire system
537 can either be installed with copies, or with moves using
540 MAKEDIRTARGET dir target [params]
541 Runs "cd $${dir} && ${MAKE} [params] $${target}",
542 displaying a "pretty" message whilst doing so.
545 Subdirectory used below RELEASEDIR when building
546 a release. [${MACHINE}]
548 RELEASEMACHINE Subdirectory or path component used for the following
550 distrib/${RELEASEMACHINE}
551 distrib/notes/${RELEASEMACHINE}
552 etc/etc.${RELEASEMACHINE}
553 Used when building a release. [${MACHINE}]
555 Additionally, the following variables may be set by <bsd.own.mk> or in a
556 make configuration file to modify the behavior of the system build
557 process (default values are in brackets along with comments, if set by
560 USETOOLS Indicates whether the tools specified by ${TOOLDIR} should
561 be used as part of a build in progress.
564 yes Use the tools from TOOLDIR.
565 Must be set to this if cross-compiling.
567 no Do not use the tools from TOOLDIR, but refuse to
568 build native compilation tool components that are
569 version-specific for that tool.
571 never Do not use the tools from TOOLDIR, even when
572 building native tool components. This is similar to
573 the traditional NetBSD build method, but does not
574 verify that the compilation tools in use are
575 up-to-date enough in order to build the tree
576 successfully. This may cause build or runtime
577 problems when building the whole NetBSD source tree.
579 Default: "yes" if building all or part of a whole NetBSD
580 source tree (detected automatically); "no" otherwise
581 (to preserve traditional semantics of the <bsd.*.mk>
582 make(1) include files).
584 OBJECT_FMT Object file format. [set to "ELF" on architectures that
585 use ELF -- currently all architectures].
588 If not "no", this indicates that the platform being built
589 does not have a working in-tree toolchain. If the
590 ${MACHINE_ARCH} in question falls into this category,
591 TOOLCHAIN_MISSING is conditionally assigned the value "yes".
592 Otherwise, the variable is unconditionally assigned the
594 If not "no", ${MKBFD}, ${MKGCC}, and ${MKGDB} are
595 unconditionally assigned the value "no".
598 This variable is not directly set by <bsd.own.mk>, but
599 including <bsd.own.mk> is the canonical way to gain
600 access to this variable. The variable should be defined
601 either in the user's environment or in the user's mk.conf
602 file. If defined, this variable indicates the root of
603 an external toolchain which will be used to build the
604 tree. For example, if a platform is a ${TOOLCHAIN_MISSING}
605 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the
606 cross-compile framework.
608 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally
609 assigned the value "no", since the external version of the
610 compiler may not be able to build the library components of
611 the in-tree compiler.
613 NOTE: This variable is not yet used in as many places as
614 it should be. Expect the exact semantics of this variable
615 to change in the short term as parts of the cross-compile
616 framework continue to be cleaned up.
618 The following variables are defined to commands to perform the
619 appropriate operation, with the default in [brackets]. Note that
620 the defaults change if USETOOLS == "yes":

758 <bsd.own.mk> is generally useful when building your own Makefiles so that
759 they use the same default owners etc. as the rest of the tree.
762 =-=-=-=-= bsd.dep.mk =-=-=-=-=
764 The include file <bsd.dep.mk> contains the default targets for building
765 .depend files. It creates .d files from entries in SRCS and DPSRCS
766 that are C, C++, or Objective C source files, and builds .depend from the
767 .d files. All other files in SRCS and all of DPSRCS will be used as
768 dependencies for the .d files. In order for this to function correctly,
769 it should be .included after all other .mk files and directives that may
770 modify SRCS or DPSRCS. It uses the following variables:
772 SRCS List of source files to build the program.
774 DPSRCS List of source files which are needed for generating
775 dependencies, but are not needed in ${SRCS}.
778 =-=-=-=-= bsd.files.mk =-=-=-=-=
780 The include file <bsd.files.mk> handles the FILES variables and is included
781 from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables:
783 FILES The list of files to install.
785 CONFIGFILES Similar semantics to FILES, except that the files
786 are installed by the `configinstall' target,
787 not the `install' target.
788 The FILES* variables documented below also apply.
790 FILESOWN File owner. [${BINOWN}]
792 FILESGRP File group. [${BINGRP}]
794 FILESMODE File mode. [${NONBINMODE}]
796 FILESDIR The location to install the files.
798 FILESNAME Optional name to install each file as.
800 FILESOWN_<fn> File owner of the specific file <fn>.
802 FILESGRP_<fn> File group of the specific file <fn>.
804 FILESMODE_<fn> File mode of the specific file <fn>.
806 FILESDIR_<fn> The location to install the specific file <fn>.
808 FILESNAME_<fn> Optional name to install <fn> as.
810 FILESBUILD_<fn> A value different from "no" will add the file to the list of
811 targets to be built by `realall'. Users of that variable
812 should provide a target to build the file.
815 BUILDSYMLINKS List of two word items:
817 For each lnsrc item, create a symlink named lntgt.
818 The lntgt symlinks are removed by the cleandir target.
820 UUDECODE_FILES List of files which are stored as <file>.uue in the source
821 tree. Each one will be decoded with ${TOOL_UUDECODE}.
822 The source files have a `.uue' suffix, the generated files do
825 UUDECODE_FILES_RENAME_<fn>
826 Rename the output from the decode to the provided name.
828 *NOTE: These files are simply decoded, with no install or other
829 rule applying implicitly except being added to the clean
832 =-=-=-=-= bsd.gcc.mk =-=-=-=-=
834 The include file <bsd.gcc.mk> computes various parameters related to GCC
835 support libraries. It defines no targets. <bsd.own.mk> MUST be included
838 The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each
839 of which need to know where to find certain GCC support libraries.
841 The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable,
842 which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then
843 the compiler is asked where to find the support libraries, otherwise the
844 support libraries are found in ${DESTDIR}/usr/lib.
846 <bsd.gcc.mk> sets the following variables:
848 _GCC_CRTBEGIN The full path name to crtbegin.o.
850 _GCC_CRTBEGINS The full path name to crtbeginS.o.
852 _GCC_CRTEND The full path name to crtend.o.
854 _GCC_CRTENDS The full path name to crtendS.o.
856 _GCC_LIBGCCDIR The directory where libgcc.a is located.
859 =-=-=-=-= bsd.inc.mk =-=-=-=-=
861 The include file <bsd.inc.mk> defines the includes target and uses the
864 INCS The list of include files.
866 INCSDIR The location to install the include files.
868 INCSNAME Target name of the include file, if only one; same as
869 FILESNAME, but for include files.
871 INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these
872 are installed in the 'includes' target and not the
873 (much later) 'install' target.
875 INCSNAME_<file> The name file <file> should be installed as, if not <file>,
876 same as FILESNAME_<file>, but for include files.
879 =-=-=-=-= bsd.info.mk =-=-=-=-=
881 The include file <bsd.info.mk> is used to generate and install GNU Info
882 documentation from respective Texinfo source files. It defines three
883 implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
886 TEXINFO List of Texinfo source files. Info documentation will
887 consist of single files with the extension replaced by
890 INFOFLAGS Flags to pass to makeinfo. []
893 =-=-=-=-= bsd.kernobj.mk =-=-=-=-=
895 The include file <bsd.kernobj.mk> defines variables related to the
896 location of kernel sources and object directories.
898 KERNSRCDIR Is the location of the top of the kernel src.
901 KERNARCHDIR Is the location of the machine dependent kernel sources.
904 KERNCONFDIR Is where the configuration files for kernels are found.
905 [${KERNSRCDIR}/${KERNARCHDIR}/conf]
907 KERNOBJDIR Is the kernel build directory. The kernel GENERIC for
908 instance will be compiled in ${KERNOBJDIR}/GENERIC.
910 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile
911 if it exists or the target 'obj' is being made.
912 Otherwise the default is
913 ${KERNSRCDIR}/${KERNARCHDIR}/compile.
915 It is important that Makefiles (such as those under src/distrib) that
916 wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR}
917 rather than make assumptions about the location of the compiled kernel.
920 =-=-=-=-= bsd.kinc.mk =-=-=-=-=
922 The include file <bsd.kinc.mk> defines the many targets (includes,
923 subdirectories, etc.), and is used by kernel makefiles to handle
924 include file installation. It is intended to be included alone, by
925 kernel Makefiles. It uses similar variables to <bsd.inc.mk>.
926 Please see <bsd.kinc.mk> for more details, and keep the documentation
927 in that file up to date.
930 =-=-=-=-= bsd.lib.mk =-=-=-=-=
932 The include file <bsd.lib.mk> has support for building libraries. It has
933 the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
934 includes, install, lint, and tags. Additionally, it has a checkver target
935 which checks for installed shared object libraries whose version is greater
936 that the version of the source. It has a limited number of suffixes,
937 consistent with the current needs of the BSD tree. <bsd.lib.mk> includes
938 <bsd.shlib.mk> to get shared library parameters.
940 It sets/uses the following variables:
942 LIB The name of the library to build.
944 LIBDIR Target directory for libraries.
946 MKARZERO Normally, ar(1) sets the timestamps, uid, gid and
947 permissions in files inside its archives to those of
948 the file it was fed. This leads to non-reproduceable
949 builds. If MKARZERO is set to "yes" (default is "no")
950 then the "D" flag is passed to ar, causing the
951 timestamp, uid and gid to be zeroed and the file
952 permissions to be set to 644. This allows .a files
953 from different builds to be bit identical.
955 SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR}
958 USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR}
959 as the path to install shared libraries to.
960 USE_SHLIBDIR must be defined before <bsd.own.mk> is included.
963 LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix),
964 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no
965 MKPROFILE=no MKSTATICLIB=no".
968 LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no
969 MKPROFILE=no", and don't install the (.a) library.
970 This is useful for "build only" helper libraries.
973 LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link
975 This is useful for C++ libraries.
978 LINTLIBDIR Target directory for lint libraries.
980 LIBGRP Library group.
982 LIBOWN Library owner.
984 LIBMODE Library mode.
986 LDADD Additional loader objects.
988 MAN The manual pages to be installed (use a .1 - .9 suffix).
991 NOCHECKVER If set, disables checking for installed shared object
992 libraries with versions greater than the source. A
993 particular library name, without the "lib" prefix, may
994 be appended to the variable name to disable the check for
997 SRCS List of source files to build the library. Suffix types
998 .s, .c, and .f are supported. Note, .s files are preferred
999 to .c files of the same name. (This is not the default for
1002 LIBDPLIBS A list of the tuples:
1003 libname path-to-srcdir-of-libname
1006 * LIBDO.libname contains the .OBJDIR of the library
1007 `libname', and if it is not set it is determined
1008 from the srcdir and added to MAKEOVERRIDES (the
1009 latter is to allow for build time optimization).
1010 * LDADD gets -L${LIBDO.libname} -llibname added.
1011 * DPADD gets ${LIBDO.libname}/liblibname.so or
1012 ${LIBDO.libname}/liblibname.a added.
1014 This variable may be used for individual libraries, as
1015 well as in parent directories to cache common libraries
1016 as a build-time optimization.
1018 The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
1019 if it exists, as well as the include file <bsd.man.mk>.
1021 It has rules for building profiled objects; profiled libraries are
1024 Libraries are ranlib'd when made.
1027 =-=-=-=-= bsd.links.mk =-=-=-=-=
1029 The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables
1030 and is included from from <bsd.lib.mk> and <bsd.prog.mk>.
1032 LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log
1033 is used. The defaults may be modified by other bsd.*.mk files which
1034 include bsd.links.mk. In the future, these variables may be replaced
1035 by a method for explicitly recording hard links in a metadata log.
1037 LINKS The list of hard links, consisting of pairs of paths:
1038 source-file target-file
1039 ${DESTDIR} is prepended to both paths before linking.
1040 For example, to link /bin/test and /bin/[, use:
1041 LINKS=/bin/test /bin/[
1043 CONFIGLINKS Similar semantics to LINKS, except that the links
1044 are installed by the `configinstall' target,
1045 not the `install' target.
1047 SYMLINKS The list of symbolic links, consisting of pairs of paths:
1048 source-file target-file
1049 ${DESTDIR} is only prepended to target-file before linking.
1050 For example, to symlink /usr/bin/tar to /bin/tar resulting
1051 in ${DESTDIR}/usr/bin/tar -> /bin/tar:
1052 SYMLINKS=/bin/tar /usr/bin/tar
1054 CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links
1055 are installed by the `configinstall' target,
1056 not the `install' target.
1058 LINKSOWN Link owner. [${BINOWN}]
1060 LINKSGRP Link group. [${BINGRP}]
1062 LINKSMODE Link mode. [${NONBINMODE}]
1064 LINKSOWN_<fn> Link owner of the specific file <fn>.
1066 LINKSGRP_<fn> Link group of the specific file <fn>.
1068 LINKSMODE_<fn> Link mode of the specific file <fn>.
1071 =-=-=-=-= bsd.man.mk =-=-=-=-=
1073 The include file <bsd.man.mk> handles installing manual pages and their
1076 It has a three targets:
1079 Install the preformatted manual pages and their links.
1081 Install the HTML manual pages and their links.
1083 Install the manual page sources and their links.
1085 It sets/uses the following variables:
1087 MANDIR Base path for manual installation.
1089 MANGRP Manual group.
1091 MANOWN Manual owner.
1093 MANMODE Manual mode.
1095 MANSUBDIR Subdirectory under the manual page section, i.e. "/vax"
1096 or "/tahoe" for machine specific manual pages.
1098 MAN The manual pages to be installed (use a .1 - .9 suffix).
1100 MLINKS List of manual page links (using a .1 - .9 suffix). The
1101 linked-to file must come first, the linked file second,
1102 and there may be multiple pairs. The files are soft-linked.
1104 The include file <bsd.man.mk> includes a file named "../Makefile.inc" if
1108 =-=-=-=-= bsd.obj.mk =-=-=-=-=
1110 The include file <bsd.obj.mk> defines targets related to the creation
1111 and use of separated object and source directories.
1113 If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses
1114 ${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if
1115 it exists. Otherwise make(1) looks for the existence of a
1116 subdirectory (or a symlink to a directory) of the source directory
1117 into which built targets should be placed. If an environment variable
1118 named MAKEOBJDIR is set, make(1) uses its value as the name of the
1119 object directory; failing that, make first looks for a subdirectory
1120 named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj".
1122 Object directories are not created automatically by make(1) if they
1123 don't exist; you need to run a separate "make obj". (This will happen
1124 during a top-level build if "MKOBJDIRS" is set to a value other than
1125 "no"). When the source directory is a subdirectory of ${BSDSRCDIR} --
1126 and this is determined by a simple string prefix comparison -- object
1127 directories are created in a separate object directory tree, and a
1128 symlink to the object directory in that tree is created in the source
1129 directory; otherwise, "make obj" assumes that you're not in the main
1130 source tree and that it's not safe to use a separate object tree.
1132 Several variables used by <bsd.obj.mk> control exactly what
1133 directories and links get created during a "make obj":
1135 MAKEOBJDIR If set, this is the component name of the object
1138 OBJMACHINE If this is set but MAKEOBJDIR is not set, creates
1139 object directories or links named "obj.${MACHINE}";
1140 otherwise, just creates ones named "obj".
1142 USR_OBJMACHINE If set, and the current directory is a subdirectory of
1143 ${BSDSRCDIR}, create object directory in the
1144 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
1145 otherwise, create it in the corresponding subdirectory
1148 BUILDID If set, the contents of this variable are appended
1149 to the object directory name. If OBJMACHINE is also
1150 set, ".${BUILDID}" is added after ".${MACHINE}".
1153 =-=-=-=-= bsd.prog.mk =-=-=-=-=
1155 The include file <bsd.prog.mk> handles building programs from one or
1156 more source files, along with their manual pages. It has a limited number
1157 of suffixes, consistent with the current needs of the BSD tree.
1158 <bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters.
1160 It has eight targets:
1163 build the program and its manual page. This also
1164 creates a GDB initialization file (.gdbinit) in
1165 the objdir. The .gdbinit file sets the shared library
1166 prefix to ${DESTDIR} to facilitate cross-debugging.
1168 remove the program, any object files and the files a.out,
1169 Errs, errs, mklog, and ${PROG}.core.
1171 remove all of the files removed by the target clean, as
1172 well as .depend, tags, and any manual pages.
1173 `distclean' is a synonym for `cleandir'.
1175 make the dependencies for the source files, and store
1176 them in the file .depend.
1178 install any header files.
1180 install the program and its manual pages; if the Makefile
1181 does not itself define the target install, the targets
1182 beforeinstall and afterinstall may also be used to cause
1183 actions immediately before and after the install target
1186 run lint on the source files
1188 create a tags file for the source files.
1190 It sets/uses the following variables:
1192 BINGRP Binary group.
1194 BINOWN Binary owner.
1196 BINMODE Binary mode.
1198 CLEANFILES Additional files to remove for the clean and cleandir targets.
1200 COPTS Additional flags to the compiler when creating C objects.
1202 COPTS.<fn> Additional flags to the compiler when creating the
1204 For <fn>.[ly], "<fn>.c" must be used.
1206 CPUFLAGS Additional flags to the compiler/assembler to select
1207 CPU instruction set options, CPU tuning options, etc.
1209 CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>.
1210 For <fn>.[ly], "<fn>.c" must be used.
1212 CPPFLAGS Additional flags to the C pre-processor.
1214 CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>.
1215 For <fn>.[ly], "<fn>.c" must be used.
1217 GDBINIT List of GDB initialization files to add to "source"
1218 directives in the .gdbinit file that is created in the
1221 LDADD Additional loader objects. Usually used for libraries.
1222 For example, to load with the compatibility and utility
1225 LDADD+=-lutil -lcompat
1227 LDFLAGS Additional linker flags (passed to ${CC} during link).
1229 LINKS See <bsd.links.mk>
1231 OBJCOPTS Additional flags to the compiler when creating ObjC objects.
1233 OBJCOPTS.<fn> Additional flags to the compiler when creating the
1234 ObjC objects for <fn>.
1235 For <fn>.[ly], "<fn>.c" must be used.
1237 SYMLINKS See <bsd.links.mk>
1239 MAN Manual pages (should end in .1 - .9). If no MAN variable is
1240 defined, "MAN=${PROG}.1" is assumed.
1242 PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link
1243 time, with the value of this variable as args to paxctl(1).
1245 PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS.
1247 PROG The name of the program to build. If not supplied, nothing
1250 PROG_CXX If defined, the name of the program to build. Also
1251 causes <bsd.prog.mk> to link the program with the C++
1252 compiler rather than the C compiler. PROG_CXX overrides
1253 the value of PROG if PROG is also set.
1255 PROGNAME The name that the above program will be installed as, if
1256 different from ${PROG}.
1258 SRCS List of source files to build the program. If SRCS is not
1259 defined, it's assumed to be ${PROG}.c.
1261 DPSRCS List of source files which are needed for generating
1262 dependencies, but are not needed in ${SRCS}.
1264 DPADD Additional dependencies for the program. Usually used for
1265 libraries. For example, to depend on the compatibility and
1266 utility libraries use:
1268 DPADD+=${LIBCOMPAT} ${LIBUTIL}
1270 The following libraries are predefined for DPADD:

1339 LIBZ?= ${DESTDIR}/usr/lib/libz.a
1341 SHAREDSTRINGS If defined, a new .c.o rule is used that results in shared
1342 strings, using xstr(1). Note that this will not work with
1345 STRIPFLAG The flag passed to the install program to cause the binary
1348 SUBDIR A list of subdirectories that should be built as well.
1349 Each of the targets will execute the same target in the
1352 SCRIPTS A list of interpreter scripts [file.{sh,csh,pl,awk,...}].
1353 These are installed exactly like programs.
1355 SCRIPTSDIR The location to install the scripts. Each script can be
1356 installed to a separate path by setting SCRIPTSDIR_<script>.
1358 SCRIPTSNAME The name that the above program will be installed as, if
1359 different from ${SCRIPTS}. These can be further specialized
1360 by setting SCRIPTSNAME_<script>.
1362 FILES See description of <bsd.files.mk>.
1364 SHLINKDIR Target directory for shared linker. See description of
1365 <bsd.own.mk> for additional information about this variable.
1367 The include file <bsd.prog.mk> includes the file named "../Makefile.inc"
1368 if it exists, as well as the include file <bsd.man.mk>.
1370 Some simple examples:
1372 To build foo from foo.c with a manual page foo.1, use:
1376 .include <bsd.prog.mk>
1378 To build foo from foo.c with a manual page foo.2, add the line:
1382 If foo does not have a manual page at all, add the line:
1386 If foo has multiple source files, add the line:
1388 SRCS= a.c b.c c.c d.c
1391 =-=-=-=-= bsd.rpc.mk =-=-=-=-=
1393 The include file <bsd.rpc.mk> contains a makefile fragment used to
1394 construct source files built by rpcgen.
1396 The following macros may be defined in makefiles which include
1397 <bsd.rpc.mk> in order to control which files get built and how they
1400 RPC_INCS: construct .h file from .x file
1401 RPC_XDRFILES: construct _xdr.c from .x file
1402 (for marshalling/unmarshalling data types)
1403 RPC_SVCFILES: construct _svc.c from .x file
1405 RPC_SVCFLAGS: Additional flags passed to builds of RPC_SVCFILES.
1407 RPC_XDIR: Directory containing .x/.h files
1410 =-=-=-=-= bsd.shlib.mk =-=-=-=-=
1412 The include file <bsd.shlib.mk> computes parameters for shared library
1413 installation and use. It defines no targets. <bsd.own.mk> MUST be
1414 included before <bsd.shlib.mk>.
1416 <bsd.own.mk> sets the following variables, if they are not already defined
1417 (defaults are in brackets):
1419 SHLIBINSTALLDIR If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR}
1420 instead of ${LIBDIR} as the base path for shared library
1421 installation. [/lib]
1423 SHLIBDIR The path to USE_SHLIBDIR shared libraries to use when building
1424 a program. [/lib for programs in /bin and /sbin, /usr/lib
1427 _LIBSODIR Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no",
1428 otherwise set to ${LIBDIR}
1430 SHLINKINSTALLDIR Base path for shared linker. [/libexec]
1432 SHLINKDIR Path to use for shared linker when building a program.
1433 [/libexec for programs in /bin and /sbin, /usr/libexec for
1437 =-=-=-=-= bsd.subdir.mk =-=-=-=-=
1439 The include file <bsd.subdir.mk> contains the default targets for building
1440 subdirectories. It has the same eight targets as <bsd.prog.mk>: all,
1441 clean, cleandir, depend, includes, install, lint, and tags. It uses the
1442 following variables:
1444 NOSUBDIR If this variable is defined, then the SUBDIR variable
1445 will be ignored and subdirectories will not be processed.
1447 SUBDIR For all of the directories listed in ${SUBDIR}, the
1448 specified directory will be visited and the target made.
1449 There is also a default target which allows the command
1450 "make subdir" where subdir is any directory listed in
1453 As a special case, the use of a token .WAIT as an
1454 entry in SUBDIR acts as a synchronization barrier
1455 when multiple make jobs are run; subdirs before the
1456 .WAIT must complete before any subdirs after .WAIT are
1457 started. See make(1) for some caveats on use of .WAIT
1458 and other special sources.
1461 =-=-=-=-= bsd.sys.mk =-=-=-=-=
1463 The include file <bsd.sys.mk> is used by <bsd.prog.mk> and
1464 <bsd.lib.mk>. It contains overrides that are used when building
1465 the NetBSD source tree.
1467 The following variables control how various files are compiled/built.

1571 WARNS Crank up GCC warning options; the distinct levels are:
1577 =-=-=-=-= bsd.x11.mk =-=-=-=-=
1579 The include file <bsd.x11.mk> contains parameters and targets for
1580 cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}.
1581 It should be included after the general Makefile contents but before
1582 the include files such as <bsd.prog.mk> and <bsd.lib.mk>.
1584 It provides the following targets:
1585 .man.1 .man.3 .man.4 .man.5 .man.7:
1586 If ${MAN} or ${PROG} is set and ${MKMAN} != "no",
1587 these rules convert from X11's manual page source
1588 into an mdoc.old source file.
