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. 10 11=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 12 13RANDOM THINGS WORTH KNOWING: 14 15The files are simply C-style #include files, and pretty much behave like 16you'd expect. The syntax is slightly different in that a single '.' is 17used instead of the hash mark, i.e. ".include <bsd.prog.mk>". 18 19One difference that will save you lots of debugging time is that inclusion 20of the file is normally done at the *end* of the Makefile. The reason for 21this is because .mk files often modify variables and behavior based on the 22values of variables set in the Makefile. To make this work, remember that 23the FIRST target found is the target that is used, i.e. if the Makefile has: 24 25 a: 26 echo a 27 a: 28 echo a number two 29 30the command "make a" will echo "a". To make things confusing, the SECOND 31variable assignment is the overriding one, i.e. if the Makefile has: 32 33 a= foo 34 a= bar 35 36 b: 37 echo ${a} 38 39the command "make b" will echo "bar". This is for compatibility with the 40way the V7 make behaved. 41 42It's fairly difficult to make the BSD .mk files work when you're building 43multiple programs in a single directory. It's a lot easier to split up the 44programs than to deal with the problem. Most of the agony comes from making 45the "obj" directory stuff work right, not because we switched to a new version 46of make. So, don't get mad at us, figure out a better way to handle multiple 47architectures so we can quit using the symbolic link stuff. (Imake doesn't 48count.) 49 50The file .depend in the source directory is expected to contain dependencies 51for the source files. This file is read automatically by make after reading 52the Makefile. 53 54The variable DESTDIR works as before. It's not set anywhere but will change 55the tree where the file gets installed. 56 57The profiled libraries are no longer built in a different directory than 58the regular libraries. A new suffix, ".po", is used to denote a profiled 59object, and ".pico" denotes a shared (position-independent) object. 60 61There are various make variables used during the build. 62 63Many variables support a (case sensitive) value of "no" or "yes", 64and are tested with ${VAR} == "no" and ${VAR} != "no" . 65 66 67The basic rule for the variable naming scheme is as follows: 68 69HOST_xxx A command that runs on the host machine regardless of 70 whether or not the system is being cross compiled, or 71 flags for such a command. 72 73MKxxx Can be set to "no" to disable functionality, or 74 "yes" to enable it. 75 Usually defaults to "yes", although some variables 76 default to "no". 77 Due to make(1) implementation issues, if a temporary 78 command-line override of a mk.conf(5) or <bsd.own.mk> 79 setting is required whilst still honoring a particular 80 Makefile's setting of MKxxx, use 81 env MKxxx=value make 82 instead of 83 make MKxxx=value 84 85NOxxx If defined, disables a feature. 86 Not intended for users. 87 This is to allow Makefiles to disable functionality 88 that they don't support (such as missing man pages). 89 NOxxx variables must be defined before <bsd.own.mk> 90 is included. 91 92TOOL_xxx A tool that is provided as part of the USETOOLS 93 framework. When not using the USETOOLS framework, 94 TOOL_xxx variables should refer to tools that are 95 already installed on the host system. 96 97The following variables that control how things are made/installed that 98are not set by default. These should not be set by Makefiles; they're for 99the user to define in MAKECONF (see <bsd.own.mk>, below, or mk.conf(5)) 100or on the make(1) command line: 101 102BUILD If defined, 'make install' checks that the targets in the 103 source directories are up-to-date and remakes them if they 104 are out of date, instead of blindly trying to install 105 out of date or non-existent targets. 106 107MAKEVERBOSE Control how "verbose" the standard make(1) rules are. 108 Default: 2 109 Supported values: 110 0 Minimal output ("quiet") 111 1 Describe what is occurring 112 2 Describe what is occurring and echo the actual command 113 3 Ignore the effect of the "@" prefix in make commands 114 4 Trace shell commands using the shell's -x flag 115 116MKATF If "no", don't build libatf-c, libatf-c++ libraries associated 117 with the Automated Testing Framework (ATF). 118 Default: yes 119 120MKBFD Obsolete, use MKBINUTILS 121 122MKBINUTILS If "no", don't build binutils (gas, ld, etc and libbfd, 123 libopcodes) 124 Default: yes 125 126MKBSDTAR If "yes", use the libarchive based cpio and tar instead of 127 the pax frontends. 128 Default: no 129 130MKCATPAGES If "no", don't build or install the catman pages. 131 Default: no 132 133MKCOMPAT If "no", don't build or install the src/compat. 134 Default: yes on amd64/mips64/sparc64, no elsewhere. 135 136MKCOMPLEX If "no", don't build libm support for <complex.h> 137 Default: yes 138 139MKCRYPTO If "no", no cryptography support will be built into the system, 140 and also acts as "MKKERBEROS=no". 141 Default: yes 142 143MKCRYPTO_RC5 If not "no", RC5 support will be built into libcrypto_rc5 144 Default: no 145 146MKCVS If "no", don't build or install cvs(1). 147 Default: yes 148 149MKDEBUG If "no", don't build and install separate debugging symbols 150 into /usr/libdata/debug. 151 Default: no 152 153MKDEBUGLIB Build *_g.a debugging libraries, which are compiled 154 with -DDEBUG. 155 Default: no 156 157MKDOC If "no", don't build or install the documentation. 158 Default: yes 159 160MKDTRACE If "no", do not build and install the kernel modules, 161 utilities and libraries used to implement the dtrace(1) 162 facility. 163 Default: no 164 165MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 166 don't install certain libraries in /lib, and don't 167 install the shared linker into /libexec. 168 Default: yes 169 170MKEXTSRC If not "no", 'make build' also descends into either src/extsrc 171 to cross-build programs and libraries externally added by 172 users, and automatically enables creation of those sets. 173 Default: no 174 175MKGCC If "no", don't build gcc(1) or any of the GCC-related 176 libraries (libgcc, libobjc, libstdc++). 177 Default: yes 178 179MKGCCCMDS If "no", don't build gcc(1), but do build the GCC-related 180 libraries (libgcc, libobjc, libstdc++). 181 Default: yes 182 183MKGDB If "no", don't build gdb(1). 184 Default: yes 185 186MKHESIOD If "no", disables building of Hesiod infrastructure 187 (libraries and support programs). 188 Default: yes 189 190MKHOSTOBJ If not "no", for programs intended to be run on the compile 191 host, the name, release, and architecture of the host 192 operating system will be suffixed to the name of the object 193 directory created by "make obj". 194 Default: no 195 196MKHTML If "no", don't build or install the HTML man pages. 197 Default: yes 198 199MKIEEEFP If "no", don't add code for IEEE754/IEC60559 conformance. 200 Has no effect on most platforms. 201 Default: yes 202 203MKSTRIPIDENT Strip the RCS IDs from program binaries and shared libraries. 204 Default: no 205 206MKINET6 If "no", disables building of INET6 (IPv6) infrastructure 207 (libraries and support programs).

The 421 stack protection code imposes a performance penalty 422 of about 5%. 423 Default: "no", unless "USE_FORT" is set to "yes" 424 425USE_FORT If "yes" turns on substitute wrappers for commonly used 426 functions that do not do bounds checking regularly, but 427 they could in some cases by using the gcc 428 __builtin_object_size() function to determine the buffer 429 size where it is known and detect buffer overflows. 430 These substitute functions are in /usr/include/ssp. 431 Default: depends on the part of the source tree 432 433USE_YP If "no", disables building YP (NIS) support into 434 various system utilities/libraries that support it. 435 If ${MKYP} is "no", USE_YP will also be forced to "no". 436 437USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 438 Otherwise, build tools/pigz and use nbpigz to compress 439 things. 440 Default: "no". 441 442X11FLAVOUR Set to "Xorg" or "XFree86", depending on whether to build 443 XFree86 or modular Xorg. Only matters if MKX11!=no. 444 Default: "Xorg" on amd64, i386, macppc, shark and sparc64, 445 "XFree86" on everything else. 446 447COPTS.lib<lib> 448OBJCOPTS.lib<lib> 449LDADD.lib<lib> 450CPPFLAGS.lib<lib> 451CXXFLAGS.lib<lib> 452COPTS.<prog> 453OBJCCOPTS.<prog> 454LDADD.<prog> 455CPPFLAGS.<prog> 456CXXFLAGS.<prog> These provide a way to specify additions to the associated 457 variables in a way that applies only to a particular library 458 or program. <lib> corresponds to the LIB variable set in 459 the library's makefile. <prog> corresponds to either PROG 460 or PROG_CXX (if set). For example, if COPTS.libcrypto is 461 set to "-g", "-g" will be added to COPTS only when compiling 462 the crypto library. 463 464The active compiler is selected using the following variables: 465AVAILABLE_COMPILER 466 List of available compiler suites. Processed in order 467 for selecting the active compiler for each frontend. 468HAVE_PCC If defined, PCC is present and enabled. 469HAVE_LLVM If defined, LLVM/Clang is present and enabled. 470UNSUPPORTED_COMPILER.xxx 471 If defined, the support for compiler "xxx" is disabled. 472 473For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 474ACTIVE_CC Active compile suite for the CC frontend. 475SUPPORTED_CC Compile suite with support for the CC frontend. 476TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 477 478=-=-=-=-= sys.mk =-=-=-=-= 479 480The include file <sys.mk> has the default rules for all makes, in the BSD 481environment or otherwise. You probably don't want to touch this file. 482 483=-=-=-=-= bsd.own.mk =-=-=-=-= 484 485The include file <bsd.own.mk> contains source tree configuration parameters, 486such as the owners, groups, etc. for both manual pages and binaries, and 487a few global "feature configuration" parameters. 488 489It has no targets. 490 491To get system-specific configuration parameters, <bsd.own.mk> will try to 492include the file specified by the "MAKECONF" variable. If MAKECONF is not 493set, or no such file exists, the system make configuration file, /etc/mk.conf 494is included. These files may define any of the variables described below. 495 496<bsd.own.mk> sets the following variables, if they are not already defined 497(defaults are in brackets): 498 499NETBSDSRCDIR Top of the NetBSD source tree. 500 If _SRC_TOP_ != "", that will be used as the default, 501 otherwise BSDSRCDIR will be used as the default. 502 Various makefiles within the NetBSD source tree will 503 use this to reference the top level of the source tree. 504 505_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 506 based on the presence of tools/ and build.sh. This variable 507 is "internal" to <bsd.own.mk>, although its value is only 508 determined once and then propagated to all sub-makes. 509 510_NETBSD_VERSION_DEPENDS 511 A list of files which contain information about 512 the version of the NetBSD being built. This is 513 defined only if the current directory appears 514 to be inside a NetBSD source tree. The list of 515 files includes ${NETBSDSRCDIR}/sys/sys/param.h 516 (which contains the kernel version number), 517 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 518 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 519 interpret the information in sys/sys/param.h), and 520 ${_SRC_TOP_OBJ_}/params (which is an optional file, 521 created by "make build" in ${_SRC_TOP_}/Makefile, 522 containing all the variables that may influence the 523 build). 524 525 Targets that depend on the NetBSD version, or on 526 variables defined at build time, can declare a 527 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 528 529 version.c: ${_NETBSD_VERSION_DEPENDS} 530 commands to create version.c 531 532BSDSRCDIR The real path to the system sources, so that 'make obj' 533 will work correctly.

[${MACHINE}] 649 650Additionally, the following variables may be set by <bsd.own.mk> or in a 651make configuration file to modify the behavior of the system build 652process (default values are in brackets along with comments, if set by 653<bsd.own.mk>): 654 655USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 656 be used as part of a build in progress. 657 Supported values: 658 659 yes Use the tools from TOOLDIR. 660 Must be set to this if cross-compiling. 661 662 no Do not use the tools from TOOLDIR, but refuse to 663 build native compilation tool components that are 664 version-specific for that tool. 665 666 never Do not use the tools from TOOLDIR, even when 667 building native tool components. This is similar to 668 the traditional NetBSD build method, but does not 669 verify that the compilation tools in use are 670 up-to-date enough in order to build the tree 671 successfully. This may cause build or runtime 672 problems when building the whole NetBSD source tree. 673 674 Default: "yes" if building all or part of a whole NetBSD 675 source tree (detected automatically); "no" otherwise 676 (to preserve traditional semantics of the <bsd.*.mk> 677 make(1) include files). 678 679OBJECT_FMT Object file format. [set to "ELF" on architectures that 680 use ELF -- currently all architectures]. 681 682TOOLCHAIN_MISSING 683 If not "no", this indicates that the platform being built 684 does not have a working in-tree toolchain. If the 685 ${MACHINE_ARCH} in question falls into this category, 686 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 687 Otherwise, the variable is unconditionally assigned the 688 value "no". 689 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 690 unconditionally assigned the value "no". 691 692EXTERNAL_TOOLCHAIN 693 This variable is not directly set by <bsd.own.mk>, but 694 including <bsd.own.mk> is the canonical way to gain 695 access to this variable. The variable should be defined 696 either in the user's environment or in the user's mk.conf 697 file. If defined, this variable indicates the root of 698 an external toolchain which will be used to build the 699 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 700 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 701 cross-compile framework. 702 703 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 704 assigned the value "no", since the external version of the 705 compiler may not be able to build the library components of 706 the in-tree compiler. 707 708 NOTE: This variable is not yet used in as many places as 709 it should be. Expect the exact semantics of this variable 710 to change in the short term as parts of the cross-compile 711 framework continue to be cleaned up. 712 713The following variables are defined to commands to perform the 714appropriate operation, with the default in [brackets].

[zic] 852 853<bsd.own.mk> is generally useful when building your own Makefiles so that 854they use the same default owners etc. as the rest of the tree. 855 856 857=-=-=-=-= bsd.clean.mk =-=-=-=-= 858 859The include file <bsd.clean.mk> defines the clean and cleandir 860targets. It uses the following variables: 861 862CLEANFILES Files to remove for both the clean and cleandir targets. 863 864CLEANDIRFILES Files to remove for the cleandir target, but not for 865 the clean target. 866 867MKCLEANSRC Controls whether or not the clean and cleandir targets 868 will delete files from both the object directory, 869 ${.OBJDIR}, and the source directory, ${.CURDIR}. 870 871 If MKCLEANSRC is set to "no", then the file names in 872 CLEANFILES or CLEANDIRFILES are interpreted relative 873 to the object directory, ${.OBJDIR}. This is the 874 traditional behaviour. 875 876 If MKCLEANSRC is set to "yes", then the file deletion 877 is performed relative to both the object directory, 878 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 879 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 880 Deleting files from ${.CURDIR} is intended to remove 881 stray output files that had been left in the source 882 directory by an earlier build that did not use object 883 directories. 884 885 The default is MKCLEANSRC=yes. If you always build with 886 separate object directories, and you are sure that there 887 are no stray files in the source directories, then you 888 may set MKCLEANSRC=no to save some time. 889 890MKCLEANVERIFY Controls whether or not the clean and cleandir targets 891 will verify that files have been deleted. 892 893 If MKCLEANVERIFY is set to "no", then the files will 894 be deleted using a "rm -f" command, and its success or 895 failure will be ignored. 896 897 If MKCLEANVERIFY is set to "yes", then the success of 898 the "rm -f" command will be verified using an "ls" 899 command. 900 901 The default is MKCLEANVERIFY=yes. If you are sure that 902 there will be no problems caused by file permissions, 903 read-only file systems, or the like, then you may set 904 MKCLEANVERIFY=no to save some time. 905 906To use the clean and cleandir targets defined in <bsd.clean.mk>, other 907Makefiles or bsd.*.mk files should append file names to the CLEANFILES 908or CLEANDIRFILES variables. For example: 909 910 CLEANFILES+= a.out 911 CLEANDIRFILES+= .depend 912 913 .include <bsd.clean.mk> 914 915The files listed in CLEANFILES and CLEANDIRFILES must not be 916directories, because the potential risk from running "rm -rf" commands 917in bsd.clean.mk is considered too great. If you want to recursively 918delete a directory as part of "make clean" or "make cleandir" then you 919need to provide your own target. 920 921=-=-=-=-= bsd.dep.mk =-=-=-=-= 922 923The include file <bsd.dep.mk> contains the default targets for building 924.depend files. It creates .d files from entries in SRCS and DPSRCS 925that are C, C++, or Objective C source files, and builds .depend from the 926.d files. All other files in SRCS and all of DPSRCS will be used as 927dependencies for the .d files. In order for this to function correctly, 928it should be .included after all other .mk files and directives that may 929modify SRCS or DPSRCS. It uses the following variables: 930 931SRCS List of source files to build the program. 932 933DPSRCS List of source files which are needed for generating 934 dependencies, but are not needed in ${SRCS}. 935 936 937=-=-=-=-= bsd.files.mk =-=-=-=-= 938 939The include file <bsd.files.mk> handles the FILES variables and is included 940from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 941 942FILES The list of files to install. 943 944CONFIGFILES Similar semantics to FILES, except that the files 945 are installed by the `configinstall' target, 946 not the `install' target. 947 The FILES* variables documented below also apply. 948 949FILESOWN File owner. [${BINOWN}] 950 951FILESGRP File group. [${BINGRP}] 952 953FILESMODE File mode. [${NONBINMODE}] 954 955FILESDIR The location to install the files. 956 957FILESNAME Optional name to install each file as. 958 959FILESOWN_<fn> File owner of the specific file <fn>. 960 961FILESGRP_<fn> File group of the specific file <fn>. 962 963FILESMODE_<fn> File mode of the specific file <fn>. 964 965FILESDIR_<fn> The location to install the specific file <fn>. 966 967FILESNAME_<fn> Optional name to install <fn> as. 968 969FILESBUILD If this variable is defined, then its value will be 970 used as the default for all FILESBUILD_<fn> variables. 971 Otherwise, the default will be "no". 972 973FILESBUILD_<fn> A value different from "no" will add the file to the list of 974 targets to be built by `realall'. Users of that variable 975 should provide a target to build the file. 976 977 978BUILDSYMLINKS List of two word items: 979 lnsrc lntgt 980 For each lnsrc item, create a symlink named lntgt. 981 The lntgt symlinks are removed by the cleandir target. 982 983UUDECODE_FILES List of files which are stored as <file>.uue in the source 984 tree. Each one will be decoded with ${TOOL_UUDECODE}. 985 The source files have a `.uue' suffix, the generated files do 986 not. 987 988UUDECODE_FILES_RENAME_<fn> 989 Rename the output from the decode to the provided name. 990 991 *NOTE: These files are simply decoded, with no install or other 992 rule applying implicitly except being added to the clean 993 target. 994 995=-=-=-=-= bsd.gcc.mk =-=-=-=-= 996 997The include file <bsd.gcc.mk> computes various parameters related to GCC 998support libraries. It defines no targets. <bsd.own.mk> MUST be included 999before <bsd.gcc.mk>. 1000 1001The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1002of which need to know where to find certain GCC support libraries. 1003 1004The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1005which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1006the compiler is asked where to find the support libraries, otherwise the 1007support libraries are found in ${DESTDIR}/usr/lib. 1008 1009<bsd.gcc.mk> sets the following variables: 1010 1011_GCC_CRTBEGIN The full path name to crtbegin.o. 1012 1013_GCC_CRTBEGINS The full path name to crtbeginS.o. 1014 1015_GCC_CRTEND The full path name to crtend.o. 1016 1017_GCC_CRTENDS The full path name to crtendS.o. 1018 1019_GCC_LIBGCCDIR The directory where libgcc.a is located. 1020 1021 1022=-=-=-=-= bsd.inc.mk =-=-=-=-= 1023 1024The include file <bsd.inc.mk> defines the includes target and uses the 1025variables: 1026 1027INCS The list of include files. 1028 1029INCSDIR The location to install the include files. 1030 1031INCSNAME Target name of the include file, if only one; same as 1032 FILESNAME, but for include files. 1033 1034INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1035 are installed in the 'includes' target and not the 1036 (much later) 'install' target. 1037 1038INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1039 same as FILESNAME_<file>, but for include files. 1040 1041 1042=-=-=-=-= bsd.info.mk =-=-=-=-= 1043 1044The include file <bsd.info.mk> is used to generate and install GNU Info 1045documentation from respective Texinfo source files. It defines three 1046implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1047following variables: 1048 1049TEXINFO List of Texinfo source files. Info documentation will 1050 consist of single files with the extension replaced by 1051 .info. 1052 1053INFOFLAGS Flags to pass to makeinfo. [] 1054 1055 1056=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1057 1058The include file <bsd.kernobj.mk> defines variables related to the 1059location of kernel sources and object directories. 1060 1061KERNSRCDIR Is the location of the top of the kernel src. 1062 [${_SRC_TOP_}/sys] 1063 1064KERNARCHDIR Is the location of the machine dependent kernel sources. 1065 [arch/${MACHINE}] 1066 1067KERNCONFDIR Is where the configuration files for kernels are found. 1068 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1069 1070KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1071 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1072 The default value is 1073 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1074 if it exists or the target 'obj' is being made. 1075 Otherwise the default is 1076 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1077 1078It is important that Makefiles (such as those under src/distrib) that 1079wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1080rather than make assumptions about the location of the compiled kernel. 1081 1082 1083=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1084 1085The include file <bsd.kinc.mk> defines the many targets (includes, 1086subdirectories, etc.), and is used by kernel makefiles to handle 1087include file installation. It is intended to be included alone, by 1088kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1089Please see <bsd.kinc.mk> for more details, and keep the documentation 1090in that file up to date. 1091 1092 1093=-=-=-=-= bsd.lib.mk =-=-=-=-= 1094 1095The include file <bsd.lib.mk> has support for building libraries. It has 1096the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1097includes, install, lint, and tags. Additionally, it has a checkver target 1098which checks for installed shared object libraries whose version is greater 1099that the version of the source. It has a limited number of suffixes, 1100consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1101<bsd.shlib.mk> to get shared library parameters. 1102 1103It sets/uses the following variables: 1104 1105LIB The name of the library to build. 1106 1107LIBDIR Target directory for libraries. 1108 1109MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1110 permissions in files inside its archives to those of 1111 the file it was fed. This leads to non-reproduceable 1112 builds. If MKARZERO is set to "yes" (default is "no") 1113 then the "D" flag is passed to ar, causing the 1114 timestamp, uid and gid to be zeroed and the file 1115 permissions to be set to 644. This allows .a files 1116 from different builds to be bit identical. 1117 1118SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1119 is not "no". 1120 1121SHLIB_MAJOR 1122SHLIB_MINOR 1123SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1124 1125USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1126 as the path to install shared libraries to. 1127 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1128 Default: no 1129 1130LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1131 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no 1132 MKPROFILE=no MKSTATICLIB=no". 1133 Default: no 1134 1135LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no 1136 MKPROFILE=no", and don't install the (.a) library. 1137 This is useful for "build only" helper libraries. 1138 Default: no 1139 1140LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1141 shared libraries. 1142 This is useful for C++ libraries. 1143 Default: no 1144 1145LINTLIBDIR Target directory for lint libraries. 1146 1147LIBGRP Library group. 1148 1149LIBOWN Library owner. 1150 1151LIBMODE Library mode. 1152 1153LDADD Additional loader objects. 1154 1155MAN The manual pages to be installed (use a .1 - .9 suffix). 1156 1157NOCHECKVER_<library> 1158NOCHECKVER If set, disables checking for installed shared object 1159 libraries with versions greater than the source. A 1160 particular library name, without the "lib" prefix, may 1161 be appended to the variable name to disable the check for 1162 only that library. 1163 1164SRCS List of source files to build the library. Suffix types 1165 .s, .c, and .f are supported. Note, .s files are preferred 1166 to .c files of the same name. (This is not the default for 1167 versions of make.) 1168 1169LIBDPLIBS A list of the tuples: 1170 libname path-to-srcdir-of-libname 1171 1172 For each tuple; 1173 * LIBDO.libname contains the .OBJDIR of the library 1174 `libname', and if it is not set it is determined 1175 from the srcdir and added to MAKEOVERRIDES (the 1176 latter is to allow for build time optimization). 1177 * LDADD gets -L${LIBDO.libname} -llibname added. 1178 * DPADD gets ${LIBDO.libname}/liblibname.so or 1179 ${LIBDO.libname}/liblibname.a added. 1180 1181 The special value "_external" for LIBDO.lib makes the 1182 build system to assume the library comes from outside 1183 of the NetBSD source tree and only causes -llibname 1184 to be added to LDADD. 1185 1186 This variable may be used for individual libraries, as 1187 well as in parent directories to cache common libraries 1188 as a build-time optimization. 1189 1190The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1191if it exists, as well as the include file <bsd.man.mk>. 1192 1193It has rules for building profiled objects; profiled libraries are 1194built by default. 1195 1196Libraries are ranlib'd when made. 1197 1198 1199=-=-=-=-= bsd.links.mk =-=-=-=-= 1200 1201The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1202and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 1203 1204LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1205is used. The defaults may be modified by other bsd.*.mk files which 1206include bsd.links.mk. In the future, these variables may be replaced 1207by a method for explicitly recording hard links in a metadata log. 1208 1209LINKS The list of hard links, consisting of pairs of paths: 1210 source-file target-file 1211 ${DESTDIR} is prepended to both paths before linking. 1212 For example, to link /bin/test and /bin/[, use: 1213 LINKS=/bin/test /bin/[ 1214 1215CONFIGLINKS Similar semantics to LINKS, except that the links 1216 are installed by the `configinstall' target, 1217 not the `install' target. 1218 1219SYMLINKS The list of symbolic links, consisting of pairs of paths: 1220 source-file target-file 1221 ${DESTDIR} is only prepended to target-file before linking. 1222 For example, to symlink /usr/bin/tar to /bin/tar resulting 1223 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1224 SYMLINKS=/bin/tar /usr/bin/tar 1225 1226CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1227 are installed by the `configinstall' target, 1228 not the `install' target. 1229 1230LINKSOWN Link owner.

The 1273 linked-to file must come first, the linked file second, 1274 and there may be multiple pairs. 1275 1276The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1277it exists. 1278 1279 1280=-=-=-=-= bsd.obj.mk =-=-=-=-= 1281 1282The include file <bsd.obj.mk> defines targets related to the creation 1283and use of separated object and source directories. 1284 1285If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1286${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1287it exists. Otherwise make(1) looks for the existence of a 1288subdirectory (or a symlink to a directory) of the source directory 1289into which built targets should be placed. If an environment variable 1290named MAKEOBJDIR is set, make(1) uses its value as the name of the 1291object directory; failing that, make first looks for a subdirectory 1292named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1293 1294Object directories are not created automatically by make(1) if they 1295don't exist; you need to run a separate "make obj". (This will happen 1296during a top-level build if "MKOBJDIRS" is set to a value other than 1297"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1298and this is determined by a simple string prefix comparison -- object 1299directories are created in a separate object directory tree, and a 1300symlink to the object directory in that tree is created in the source 1301directory; otherwise, "make obj" assumes that you're not in the main 1302source tree and that it's not safe to use a separate object tree. 1303 1304Several variables used by <bsd.obj.mk> control exactly what 1305directories and links get created during a "make obj": 1306 1307MAKEOBJDIR If set, this is the component name of the object 1308 directory. 1309 1310OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1311 object directories or links named "obj.${MACHINE}"; 1312 otherwise, just creates ones named "obj". 1313 1314USR_OBJMACHINE If set, and the current directory is a subdirectory of 1315 ${BSDSRCDIR}, create object directory in the 1316 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1317 otherwise, create it in the corresponding subdirectory 1318 of ${BSDOBJDIR} 1319 1320BUILDID If set, the contents of this variable are appended 1321 to the object directory name. If OBJMACHINE is also 1322 set, ".${BUILDID}" is added after ".${MACHINE}". 1323 1324 1325=-=-=-=-= bsd.prog.mk =-=-=-=-= 1326 1327The include file <bsd.prog.mk> handles building programs from one or 1328more source files, along with their manual pages. It has a limited number 1329of suffixes, consistent with the current needs of the BSD tree. 1330<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1331 1332It has eight targets: 1333 1334 all: 1335 build the program and its manual page. This also 1336 creates a GDB initialization file (.gdbinit) in 1337 the objdir. The .gdbinit file sets the shared library 1338 prefix to ${DESTDIR} to facilitate cross-debugging. 1339 clean: 1340 remove the program, any object files and the files a.out, 1341 Errs, errs, mklog, and ${PROG}.core. 1342 cleandir: 1343 remove all of the files removed by the target clean, as 1344 well as .depend, tags, and any manual pages. 1345 `distclean' is a synonym for `cleandir'. 1346 depend: 1347 make the dependencies for the source files, and store 1348 them in the file .depend. 1349 includes: 1350 install any header files. 1351 install: 1352 install the program and its manual pages; if the Makefile 1353 does not itself define the target install, the targets 1354 beforeinstall and afterinstall may also be used to cause 1355 actions immediately before and after the install target 1356 is executed. 1357 lint: 1358 run lint on the source files 1359 tags: 1360 create a tags file for the source files. 1361 1362It sets/uses the following variables: 1363 1364BINGRP Binary group. 1365 1366BINOWN Binary owner. 1367 1368BINMODE Binary mode. 1369 1370CLEANDIRFILES Additional files to remove for the cleandir target. 1371 1372CLEANFILES Additional files to remove for the clean and cleandir targets. 1373 1374COPTS Additional flags to the compiler when creating C objects. 1375 1376COPTS.<fn> Additional flags to the compiler when creating the 1377 C objects for <fn>. 1378 For <fn>.[ly], "<fn>.c" must be used. 1379 1380CPUFLAGS Additional flags to the compiler/assembler to select 1381 CPU instruction set options, CPU tuning options, etc. 1382 1383CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1384 For <fn>.[ly], "<fn>.c" must be used. 1385 1386CPPFLAGS Additional flags to the C pre-processor. 1387 1388CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1389 For <fn>.[ly], "<fn>.c" must be used. 1390 1391GDBINIT List of GDB initialization files to add to "source" 1392 directives in the .gdbinit file that is created in the 1393 objdir. 1394 1395LDADD Additional loader objects. Usually used for libraries. 1396 For example, to load with the compatibility and utility 1397 libraries, use: 1398 1399 LDADD+=-lutil -lcompat 1400 1401LDFLAGS Additional linker flags (passed to ${CC} during link). 1402 1403LINKS See <bsd.links.mk> 1404 1405OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1406 1407OBJCOPTS.<fn> Additional flags to the compiler when creating the 1408 ObjC objects for <fn>. 1409 For <fn>.[ly], "<fn>.c" must be used. 1410 1411SYMLINKS See <bsd.links.mk> 1412 1413MAN Manual pages (should end in .1 - .9). If no MAN variable is 1414 defined, "MAN=${PROG}.1" is assumed. 1415 1416PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1417 time, with the value of this variable as args to paxctl(1). 1418 1419PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1420 1421PROG The name of the program to build. If not supplied, nothing 1422 is built. 1423 1424PROG_CXX If defined, the name of the program to build. Also 1425 causes <bsd.prog.mk> to link the program with the C++ 1426 compiler rather than the C compiler. PROG_CXX overrides 1427 the value of PROG if PROG is also set. 1428 1429PROGNAME The name that the above program will be installed as, if 1430 different from ${PROG}. 1431 1432SRCS List of source files to build the program. If SRCS is not 1433 defined, it's assumed to be ${PROG}.c. 1434 1435DPSRCS List of source files which are needed for generating 1436 dependencies, but are not needed in ${SRCS}. 1437 1438DPADD Additional dependencies for the program. Usually used for 1439 libraries. For example, to depend on the compatibility and 1440 utility libraries use: 1441 1442 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1443 1444 The following system libraries are predefined for DPADD: 1445 1446

It uses the 1691following variables: 1692 1693NOSUBDIR If this variable is defined, then the SUBDIR variable 1694 will be ignored and subdirectories will not be processed. 1695 1696SUBDIR For all of the directories listed in ${SUBDIR}, the 1697 specified directory will be visited and the target made. 1698 1699 As a special case, the use of a token .WAIT as an 1700 entry in SUBDIR acts as a synchronization barrier 1701 when multiple make jobs are run; subdirs before the 1702 .WAIT must complete before any subdirs after .WAIT are 1703 started. See make(1) for some caveats on use of .WAIT 1704 and other special sources. 1705 1706 1707=-=-=-=-= bsd.sys.mk =-=-=-=-= 1708 1709The include file <bsd.sys.mk> is used by <bsd.prog.mk> and 1710<bsd.lib.mk>.
