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 417 stack protection code imposes a performance penalty 418 of about 5%. 419 Default: "no", unless "USE_FORT" is set to "yes" 420 421USE_FORT If "yes" turns on substitute wrappers for commonly used 422 functions that do not do bounds checking regularly, but 423 they could in some cases by using the gcc 424 __builtin_object_size() function to determine the buffer 425 size where it is known and detect buffer overflows. 426 These substitute functions are in /usr/include/ssp. 427 Default: depends on the part of the source tree 428 429USE_YP If "no", disables building YP (NIS) support into 430 various system utilities/libraries that support it. 431 If ${MKYP} is "no", USE_YP will also be forced to "no". 432 433USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 434 Otherwise, build tools/pigz and use nbpigz to compress 435 things. 436 Default: "no". 437 438X11FLAVOUR Set to "Xorg" or "XFree86", depending on whether to build 439 XFree86 or modular Xorg. Only matters if MKX11!=no. 440 Default: "Xorg" on amd64, i386, macppc, shark and sparc64, 441 "XFree86" on everything else. 442 443COPTS.lib<lib> 444OBJCOPTS.lib<lib> 445LDADD.lib<lib> 446CPPFLAGS.lib<lib> 447CXXFLAGS.lib<lib> 448COPTS.<prog> 449OBJCCOPTS.<prog> 450LDADD.<prog> 451CPPFLAGS.<prog> 452CXXFLAGS.<prog> These provide a way to specify additions to the associated 453 variables in a way that applies only to a particular library 454 or program. <lib> corresponds to the LIB variable set in 455 the library's makefile. <prog> corresponds to either PROG 456 or PROG_CXX (if set). For example, if COPTS.libcrypto is 457 set to "-g", "-g" will be added to COPTS only when compiling 458 the crypto library. 459 460The active compiler is selected using the following variables: 461AVAILABLE_COMPILER 462 List of available compiler suites. Processed in order 463 for selecting the active compiler for each frontend. 464HAVE_PCC If defined, PCC is present and enabled. 465HAVE_LLVM If defined, LLVM/Clang is present and enabled. 466UNSUPPORTED_COMPILER.xxx 467 If defined, the support for compiler "xxx" is disabled. 468 469For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 470ACTIVE_CC Active compile suite for the CC frontend. 471SUPPORTED_CC Compile suite with support for the CC frontend. 472TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 473 474=-=-=-=-= sys.mk =-=-=-=-= 475 476The include file <sys.mk> has the default rules for all makes, in the BSD 477environment or otherwise. You probably don't want to touch this file. 478 479=-=-=-=-= bsd.own.mk =-=-=-=-= 480 481The include file <bsd.own.mk> contains source tree configuration parameters, 482such as the owners, groups, etc. for both manual pages and binaries, and 483a few global "feature configuration" parameters. 484 485It has no targets. 486 487To get system-specific configuration parameters, <bsd.own.mk> will try to 488include the file specified by the "MAKECONF" variable. If MAKECONF is not 489set, or no such file exists, the system make configuration file, /etc/mk.conf 490is included. These files may define any of the variables described below. 491 492<bsd.own.mk> sets the following variables, if they are not already defined 493(defaults are in brackets): 494 495NETBSDSRCDIR Top of the NetBSD source tree. 496 If _SRC_TOP_ != "", that will be used as the default, 497 otherwise BSDSRCDIR will be used as the default. 498 Various makefiles within the NetBSD source tree will 499 use this to reference the top level of the source tree. 500 501_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 502 based on the presence of tools/ and build.sh. This variable 503 is "internal" to <bsd.own.mk>, although its value is only 504 determined once and then propagated to all sub-makes. 505 506_NETBSD_VERSION_DEPENDS 507 A list of files which contain information about 508 the version of the NetBSD being built. This is 509 defined only if the current directory appears 510 to be inside a NetBSD source tree. The list of 511 files includes ${NETBSDSRCDIR}/sys/sys/param.h 512 (which contains the kernel version number), 513 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 514 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 515 interpret the information in sys/sys/param.h), and 516 ${_SRC_TOP_OBJ_}/params (which is an optional file, 517 created by "make build" in ${_SRC_TOP_}/Makefile, 518 containing all the variables that may influence the 519 build). 520 521 Targets that depend on the NetBSD version, or on 522 variables defined at build time, can declare a 523 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 524 525 version.c: ${_NETBSD_VERSION_DEPENDS} 526 commands to create version.c 527 528BSDSRCDIR The real path to the system sources, so that 'make obj' 529 will work correctly.

[${MACHINE}] 641 642Additionally, the following variables may be set by <bsd.own.mk> or in a 643make configuration file to modify the behavior of the system build 644process (default values are in brackets along with comments, if set by 645<bsd.own.mk>): 646 647USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 648 be used as part of a build in progress. 649 Supported values: 650 651 yes Use the tools from TOOLDIR. 652 Must be set to this if cross-compiling. 653 654 no Do not use the tools from TOOLDIR, but refuse to 655 build native compilation tool components that are 656 version-specific for that tool. 657 658 never Do not use the tools from TOOLDIR, even when 659 building native tool components. This is similar to 660 the traditional NetBSD build method, but does not 661 verify that the compilation tools in use are 662 up-to-date enough in order to build the tree 663 successfully. This may cause build or runtime 664 problems when building the whole NetBSD source tree. 665 666 Default: "yes" if building all or part of a whole NetBSD 667 source tree (detected automatically); "no" otherwise 668 (to preserve traditional semantics of the <bsd.*.mk> 669 make(1) include files). 670 671OBJECT_FMT Object file format. [set to "ELF" on architectures that 672 use ELF -- currently all architectures]. 673 674TOOLCHAIN_MISSING 675 If not "no", this indicates that the platform being built 676 does not have a working in-tree toolchain. If the 677 ${MACHINE_ARCH} in question falls into this category, 678 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 679 Otherwise, the variable is unconditionally assigned the 680 value "no". 681 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 682 unconditionally assigned the value "no". 683 684EXTERNAL_TOOLCHAIN 685 This variable is not directly set by <bsd.own.mk>, but 686 including <bsd.own.mk> is the canonical way to gain 687 access to this variable. The variable should be defined 688 either in the user's environment or in the user's mk.conf 689 file. If defined, this variable indicates the root of 690 an external toolchain which will be used to build the 691 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 692 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 693 cross-compile framework. 694 695 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 696 assigned the value "no", since the external version of the 697 compiler may not be able to build the library components of 698 the in-tree compiler. 699 700 NOTE: This variable is not yet used in as many places as 701 it should be. Expect the exact semantics of this variable 702 to change in the short term as parts of the cross-compile 703 framework continue to be cleaned up. 704 705The following variables are defined to commands to perform the 706appropriate operation, with the default in [brackets].

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

The 1260 linked-to file must come first, the linked file second, 1261 and there may be multiple pairs. 1262 1263The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1264it exists. 1265 1266 1267=-=-=-=-= bsd.obj.mk =-=-=-=-= 1268 1269The include file <bsd.obj.mk> defines targets related to the creation 1270and use of separated object and source directories. 1271 1272If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1273${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1274it exists. Otherwise make(1) looks for the existence of a 1275subdirectory (or a symlink to a directory) of the source directory 1276into which built targets should be placed. If an environment variable 1277named MAKEOBJDIR is set, make(1) uses its value as the name of the 1278object directory; failing that, make first looks for a subdirectory 1279named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1280 1281Object directories are not created automatically by make(1) if they 1282don't exist; you need to run a separate "make obj". (This will happen 1283during a top-level build if "MKOBJDIRS" is set to a value other than 1284"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1285and this is determined by a simple string prefix comparison -- object 1286directories are created in a separate object directory tree, and a 1287symlink to the object directory in that tree is created in the source 1288directory; otherwise, "make obj" assumes that you're not in the main 1289source tree and that it's not safe to use a separate object tree. 1290 1291Several variables used by <bsd.obj.mk> control exactly what 1292directories and links get created during a "make obj": 1293 1294MAKEOBJDIR If set, this is the component name of the object 1295 directory. 1296 1297OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1298 object directories or links named "obj.${MACHINE}"; 1299 otherwise, just creates ones named "obj". 1300 1301USR_OBJMACHINE If set, and the current directory is a subdirectory of 1302 ${BSDSRCDIR}, create object directory in the 1303 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1304 otherwise, create it in the corresponding subdirectory 1305 of ${BSDOBJDIR} 1306 1307BUILDID If set, the contents of this variable are appended 1308 to the object directory name. If OBJMACHINE is also 1309 set, ".${BUILDID}" is added after ".${MACHINE}". 1310 1311 1312=-=-=-=-= bsd.prog.mk =-=-=-=-= 1313 1314The include file <bsd.prog.mk> handles building programs from one or 1315more source files, along with their manual pages. It has a limited number 1316of suffixes, consistent with the current needs of the BSD tree. 1317<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1318 1319It has eight targets: 1320 1321 all: 1322 build the program and its manual page. This also 1323 creates a GDB initialization file (.gdbinit) in 1324 the objdir. The .gdbinit file sets the shared library 1325 prefix to ${DESTDIR} to facilitate cross-debugging. 1326 clean: 1327 remove the program, any object files and the files a.out, 1328 Errs, errs, mklog, and ${PROG}.core. 1329 cleandir: 1330 remove all of the files removed by the target clean, as 1331 well as .depend, tags, and any manual pages. 1332 `distclean' is a synonym for `cleandir'. 1333 depend: 1334 make the dependencies for the source files, and store 1335 them in the file .depend. 1336 includes: 1337 install any header files. 1338 install: 1339 install the program and its manual pages; if the Makefile 1340 does not itself define the target install, the targets 1341 beforeinstall and afterinstall may also be used to cause 1342 actions immediately before and after the install target 1343 is executed. 1344 lint: 1345 run lint on the source files 1346 tags: 1347 create a tags file for the source files. 1348 1349It sets/uses the following variables: 1350 1351BINGRP Binary group. 1352 1353BINOWN Binary owner. 1354 1355BINMODE Binary mode. 1356 1357CLEANDIRFILES Additional files to remove for the cleandir target. 1358 1359CLEANFILES Additional files to remove for the clean and cleandir targets. 1360 1361COPTS Additional flags to the compiler when creating C objects. 1362 1363COPTS.<fn> Additional flags to the compiler when creating the 1364 C objects for <fn>. 1365 For <fn>.[ly], "<fn>.c" must be used. 1366 1367CPUFLAGS Additional flags to the compiler/assembler to select 1368 CPU instruction set options, CPU tuning options, etc. 1369 1370CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1371 For <fn>.[ly], "<fn>.c" must be used. 1372 1373CPPFLAGS Additional flags to the C pre-processor. 1374 1375CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1376 For <fn>.[ly], "<fn>.c" must be used. 1377 1378GDBINIT List of GDB initialization files to add to "source" 1379 directives in the .gdbinit file that is created in the 1380 objdir. 1381 1382LDADD Additional loader objects. Usually used for libraries. 1383 For example, to load with the compatibility and utility 1384 libraries, use: 1385 1386 LDADD+=-lutil -lcompat 1387 1388LDFLAGS Additional linker flags (passed to ${CC} during link). 1389 1390LINKS See <bsd.links.mk> 1391 1392OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1393 1394OBJCOPTS.<fn> Additional flags to the compiler when creating the 1395 ObjC objects for <fn>. 1396 For <fn>.[ly], "<fn>.c" must be used. 1397 1398SYMLINKS See <bsd.links.mk> 1399 1400MAN Manual pages (should end in .1 - .9). If no MAN variable is 1401 defined, "MAN=${PROG}.1" is assumed. 1402 1403PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1404 time, with the value of this variable as args to paxctl(1). 1405 1406PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1407 1408PROG The name of the program to build. If not supplied, nothing 1409 is built. 1410 1411PROG_CXX If defined, the name of the program to build. Also 1412 causes <bsd.prog.mk> to link the program with the C++ 1413 compiler rather than the C compiler. PROG_CXX overrides 1414 the value of PROG if PROG is also set. 1415 1416PROGNAME The name that the above program will be installed as, if 1417 different from ${PROG}. 1418 1419SRCS List of source files to build the program. If SRCS is not 1420 defined, it's assumed to be ${PROG}.c. 1421 1422DPSRCS List of source files which are needed for generating 1423 dependencies, but are not needed in ${SRCS}. 1424 1425DPADD Additional dependencies for the program. Usually used for 1426 libraries.
