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 the Automated Testing Framework (ATF), 117 which includes the libatf-c, libatf-c++ and libatf-sh libraries 118 and the various command line tools. Also, because the build of 119 the libraries is disabled, don't build the NetBSD test suite 120 either. 121 Default: yes 122 123MKBFD Obsolete, use MKBINUTILS 124 125MKBINUTILS If "no", don't build binutils (gas, ld, etc and libbfd, 126 libopcodes) 127 Default: yes 128 129MKBSDTAR If "yes", use the libarchive based cpio and tar instead of 130 the pax frontends. 131 Default: no 132 133MKCATPAGES If "no", don't build or install the catman pages. 134 Default: no 135 136MKCOMPAT If "no", don't build or install the src/compat. 137 Default: yes on amd64/mips64/sparc64, no elsewhere. 138 139MKCOMPLEX If "no", don't build libm support for <complex.h> 140 Default: yes 141 142MKCRYPTO If "no", no cryptography support will be built into the system, 143 and also acts as "MKKERBEROS=no". 144 Default: yes 145 146MKCRYPTO_RC5 If not "no", RC5 support will be built into libcrypto_rc5 147 Default: no 148 149MKCTF If "no", do not build and install CTF tools, and also 150 don't generate and manipulate CTF data of ELF binaries 151 during build. 152 Default: no 153 154MKCVS If "no", don't build or install cvs(1). 155 Default: yes 156 157MKDEBUG If "no", don't build and install separate debugging symbols 158 into /usr/libdata/debug. 159 Default: no 160 161MKDEBUGLIB Build *_g.a debugging libraries, which are compiled 162 with -DDEBUG. 163 Default: no 164 165MKDEPINCLUDES If "yes" issue .include statements in the .depend file 166 instead of inlining the contents of the .d files. Useful 167 when stale dependencies are present, to list the exact 168 files that need refreshing. It is off by default because 169 it is possibly slower. 170 Default "no" 171 172MKDOC If "no", don't build or install the documentation. 173 Default: yes 174 175MKDTRACE If "no", do not build and install the kernel modules, 176 utilities and libraries used to implement the dtrace(1) 177 facility. 178 Default: no 179 180MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 181 don't install certain libraries in /lib, and don't 182 install the shared linker into /libexec. 183 Default: yes 184 185MKEXTSRC If not "no", 'make build' also descends into either src/extsrc 186 to cross-build programs and libraries externally added by 187 users, and automatically enables creation of those sets. 188 Default: no 189 190MKGCC If "no", don't build gcc(1) or any of the GCC-related 191 libraries (libgcc, libobjc, libstdc++). 192 Default: yes 193 194MKGCCCMDS If "no", don't build gcc(1), but do build the GCC-related 195 libraries (libgcc, libobjc, libstdc++). 196 Default: yes 197 198MKGDB If "no", don't build gdb(1). 199 Default: yes 200 201MKGROFFHTMLDOC If "no", avoid trying to use groff to generate html for 202 miscellaneous articles, as this seems to sometimes want 203 to run software not in base.

The 464 stack protection code imposes a performance penalty 465 of about 5%. 466 Default: "no", unless "USE_FORT" is set to "yes" 467 468USE_FORT If "yes" turns on substitute wrappers for commonly used 469 functions that do not do bounds checking regularly, but 470 they could in some cases by using the gcc 471 __builtin_object_size() function to determine the buffer 472 size where it is known and detect buffer overflows. 473 These substitute functions are in /usr/include/ssp. 474 Default: depends on the part of the source tree 475 476USE_YP If "no", disables building YP (NIS) support into 477 various system utilities/libraries that support it. 478 If ${MKYP} is "no", USE_YP will also be forced to "no". 479 480USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 481 Otherwise, build tools/pigz, set TOOL_GZIP=${TOOL_PIGZ}, 482 and use nbpigz to compress things. 483 Default: "no". 484 485X11FLAVOUR Set to "Xorg" or "XFree86", depending on whether to build 486 XFree86 or modular Xorg. Only matters if MKX11!=no. 487 Default: "Xorg" on amd64, i386, macppc, shark and sparc64, 488 "XFree86" on everything else. 489 490COPTS.lib<lib> 491OBJCOPTS.lib<lib> 492LDADD.lib<lib> 493CPPFLAGS.lib<lib> 494CXXFLAGS.lib<lib> 495COPTS.<prog> 496OBJCCOPTS.<prog> 497LDADD.<prog> 498CPPFLAGS.<prog> 499CXXFLAGS.<prog> These provide a way to specify additions to the associated 500 variables in a way that applies only to a particular library 501 or program. <lib> corresponds to the LIB variable set in 502 the library's makefile. <prog> corresponds to either PROG 503 or PROG_CXX (if set). For example, if COPTS.libcrypto is 504 set to "-g", "-g" will be added to COPTS only when compiling 505 the crypto library. 506 507The active compiler is selected using the following variables: 508AVAILABLE_COMPILER 509 List of available compiler suites. Processed in order 510 for selecting the active compiler for each frontend. 511HAVE_PCC If defined, PCC is present and enabled. 512HAVE_LLVM If defined, LLVM/Clang is present and enabled. 513UNSUPPORTED_COMPILER.xxx 514 If defined, the support for compiler "xxx" is disabled. 515 516For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 517ACTIVE_CC Active compile suite for the CC frontend. 518SUPPORTED_CC Compile suite with support for the CC frontend. 519TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 520 521=-=-=-=-= sys.mk =-=-=-=-= 522 523The include file <sys.mk> has the default rules for all makes, in the BSD 524environment or otherwise. You probably don't want to touch this file. 525 526=-=-=-=-= bsd.own.mk =-=-=-=-= 527 528The include file <bsd.own.mk> contains source tree configuration parameters, 529such as the owners, groups, etc. for both manual pages and binaries, and 530a few global "feature configuration" parameters. 531 532It has no targets. 533 534To get system-specific configuration parameters, <bsd.own.mk> will try to 535include the file specified by the "MAKECONF" variable. If MAKECONF is not 536set, or no such file exists, the system make configuration file, /etc/mk.conf 537is included. These files may define any of the variables described below. 538 539<bsd.own.mk> sets the following variables, if they are not already defined 540(defaults are in brackets): 541 542NETBSDSRCDIR Top of the NetBSD source tree. 543 If _SRC_TOP_ != "", that will be used as the default, 544 otherwise BSDSRCDIR will be used as the default. 545 Various makefiles within the NetBSD source tree will 546 use this to reference the top level of the source tree. 547 548_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 549 based on the presence of tools/ and build.sh. This variable 550 is "internal" to <bsd.own.mk>, although its value is only 551 determined once and then propagated to all sub-makes. 552 553_NETBSD_VERSION_DEPENDS 554 A list of files which contain information about 555 the version of the NetBSD being built. This is 556 defined only if the current directory appears 557 to be inside a NetBSD source tree. The list of 558 files includes ${NETBSDSRCDIR}/sys/sys/param.h 559 (which contains the kernel version number), 560 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 561 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 562 interpret the information in sys/sys/param.h), and 563 ${_SRC_TOP_OBJ_}/params (which is an optional file, 564 created by "make build" in ${_SRC_TOP_}/Makefile, 565 containing all the variables that may influence the 566 build). 567 568 Targets that depend on the NetBSD version, or on 569 variables defined at build time, can declare a 570 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 571 572 version.c: ${_NETBSD_VERSION_DEPENDS} 573 commands to create version.c 574 575BSDSRCDIR The real path to the system sources, so that 'make obj' 576 will work correctly.

[] 664 665COPY The flag passed to the install program to cause the binary 666 to be copied rather than moved. This is to be used when 667 building our own install script so that the entire system 668 can either be installed with copies, or with moves using 669 a single knob. [-c] 670 671MAKEDIRTARGETENV 672 Environment variables passed to the child make process 673 invoked by MAKEDIRTARGET. 674 675MAKEDIRTARGET dir target [params] 676 Runs "cd $${dir} && ${MAKE} [params] $${target}", 677 displaying a "pretty" message whilst doing so. 678 679RELEASEMACHINEDIR 680 Subdirectory used below RELEASEDIR when building 681 a release.

[${MACHINE}] 689 690Additionally, the following variables may be set by <bsd.own.mk> or in a 691make configuration file to modify the behavior of the system build 692process (default values are in brackets along with comments, if set by 693<bsd.own.mk>): 694 695USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 696 be used as part of a build in progress. 697 Supported values: 698 699 yes Use the tools from TOOLDIR. 700 Must be set to this if cross-compiling. 701 702 no Do not use the tools from TOOLDIR, but refuse to 703 build native compilation tool components that are 704 version-specific for that tool. 705 706 never Do not use the tools from TOOLDIR, even when 707 building native tool components. This is similar to 708 the traditional NetBSD build method, but does not 709 verify that the compilation tools in use are 710 up-to-date enough in order to build the tree 711 successfully. This may cause build or runtime 712 problems when building the whole NetBSD source tree. 713 714 Default: "yes" if building all or part of a whole NetBSD 715 source tree (detected automatically); "no" otherwise 716 (to preserve traditional semantics of the <bsd.*.mk> 717 make(1) include files). 718 719OBJECT_FMT Object file format. [set to "ELF" on architectures that 720 use ELF -- currently all architectures]. 721 722TOOLCHAIN_MISSING 723 If not "no", this indicates that the platform being built 724 does not have a working in-tree toolchain. If the 725 ${MACHINE_ARCH} in question falls into this category, 726 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 727 Otherwise, the variable is unconditionally assigned the 728 value "no". 729 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 730 unconditionally assigned the value "no". 731 732EXTERNAL_TOOLCHAIN 733 This variable is not directly set by <bsd.own.mk>, but 734 including <bsd.own.mk> is the canonical way to gain 735 access to this variable. The variable should be defined 736 either in the user's environment or in the user's mk.conf 737 file. If defined, this variable indicates the root of 738 an external toolchain which will be used to build the 739 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 740 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 741 cross-compile framework. 742 743 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 744 assigned the value "no", since the external version of the 745 compiler may not be able to build the library components of 746 the in-tree compiler. 747 748 NOTE: This variable is not yet used in as many places as 749 it should be. Expect the exact semantics of this variable 750 to change in the short term as parts of the cross-compile 751 framework continue to be cleaned up. 752 753The following variables are defined to commands to perform the 754appropriate operation, with the default in [brackets].

This keeps those definitions in 901centralized place. 902 903<bsd.own.mk> is generally useful when building your own Makefiles so that 904they use the same default owners etc. as the rest of the tree. 905 906 907=-=-=-=-= bsd.clean.mk =-=-=-=-= 908 909The include file <bsd.clean.mk> defines the clean and cleandir 910targets. It uses the following variables: 911 912CLEANFILES Files to remove for both the clean and cleandir targets. 913 914CLEANDIRFILES Files to remove for the cleandir target, but not for 915 the clean target. 916 917MKCLEANSRC Controls whether or not the clean and cleandir targets 918 will delete files from both the object directory, 919 ${.OBJDIR}, and the source directory, ${.CURDIR}. 920 921 If MKCLEANSRC is set to "no", then the file names in 922 CLEANFILES or CLEANDIRFILES are interpreted relative 923 to the object directory, ${.OBJDIR}. This is the 924 traditional behaviour. 925 926 If MKCLEANSRC is set to "yes", then the file deletion 927 is performed relative to both the object directory, 928 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 929 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 930 Deleting files from ${.CURDIR} is intended to remove 931 stray output files that had been left in the source 932 directory by an earlier build that did not use object 933 directories. 934 935 The default is MKCLEANSRC=yes. If you always build with 936 separate object directories, and you are sure that there 937 are no stray files in the source directories, then you 938 may set MKCLEANSRC=no to save some time. 939 940MKCLEANVERIFY Controls whether or not the clean and cleandir targets 941 will verify that files have been deleted. 942 943 If MKCLEANVERIFY is set to "no", then the files will 944 be deleted using a "rm -f" command, and its success or 945 failure will be ignored. 946 947 If MKCLEANVERIFY is set to "yes", then the success of 948 the "rm -f" command will be verified using an "ls" 949 command. 950 951 The default is MKCLEANVERIFY=yes. If you are sure that 952 there will be no problems caused by file permissions, 953 read-only file systems, or the like, then you may set 954 MKCLEANVERIFY=no to save some time. 955 956To use the clean and cleandir targets defined in <bsd.clean.mk>, other 957Makefiles or bsd.*.mk files should append file names to the CLEANFILES 958or CLEANDIRFILES variables. For example: 959 960 CLEANFILES+= a.out 961 CLEANDIRFILES+= .depend 962 963 .include <bsd.clean.mk> 964 965The files listed in CLEANFILES and CLEANDIRFILES must not be 966directories, because the potential risk from running "rm -rf" commands 967in bsd.clean.mk is considered too great. If you want to recursively 968delete a directory as part of "make clean" or "make cleandir" then you 969need to provide your own target. 970 971=-=-=-=-= bsd.dep.mk =-=-=-=-= 972 973The include file <bsd.dep.mk> contains the default targets for building 974.depend files. It creates .d files from entries in SRCS and DPSRCS 975that are C, C++, or Objective C source files, and builds .depend from the 976.d files. All other files in SRCS and all of DPSRCS will be used as 977dependencies for the .d files. In order for this to function correctly, 978it should be .included after all other .mk files and directives that may 979modify SRCS or DPSRCS. It uses the following variables: 980 981SRCS List of source files to build the program. 982 983DPSRCS List of source files which are needed for generating 984 dependencies, but are not needed in ${SRCS}. 985 986 987=-=-=-=-= bsd.files.mk =-=-=-=-= 988 989The include file <bsd.files.mk> handles the FILES variables and is included 990from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 991 992FILES The list of files to install. 993 994CONFIGFILES Similar semantics to FILES, except that the files 995 are installed by the `configinstall' target, 996 not the `install' target. 997 The FILES* variables documented below also apply. 998 999FILESOWN File owner. [${BINOWN}] 1000 1001FILESGRP File group. [${BINGRP}] 1002 1003FILESMODE File mode. [${NONBINMODE}] 1004 1005FILESDIR The location to install the files. 1006 1007FILESNAME Optional name to install each file as. 1008 1009FILESOWN_<fn> File owner of the specific file <fn>. 1010 1011FILESGRP_<fn> File group of the specific file <fn>. 1012 1013FILESMODE_<fn> File mode of the specific file <fn>. 1014 1015FILESDIR_<fn> The location to install the specific file <fn>. 1016 1017FILESNAME_<fn> Optional name to install <fn> as. 1018 1019FILESBUILD If this variable is defined, then its value will be 1020 used as the default for all FILESBUILD_<fn> variables. 1021 Otherwise, the default will be "no". 1022 1023FILESBUILD_<fn> A value different from "no" will add the file to the list of 1024 targets to be built by `realall'. Users of that variable 1025 should provide a target to build the file. 1026 1027 1028BUILDSYMLINKS List of two word items: 1029 lnsrc lntgt 1030 For each lnsrc item, create a symlink named lntgt. 1031 The lntgt symlinks are removed by the cleandir target. 1032 1033UUDECODE_FILES List of files which are stored as <file>.uue in the source 1034 tree. Each one will be decoded with ${TOOL_UUDECODE}. 1035 The source files have a `.uue' suffix, the generated files do 1036 not. 1037 1038UUDECODE_FILES_RENAME_<fn> 1039 Rename the output from the decode to the provided name. 1040 1041 *NOTE: These files are simply decoded, with no install or other 1042 rule applying implicitly except being added to the clean 1043 target. 1044 1045=-=-=-=-= bsd.gcc.mk =-=-=-=-= 1046 1047The include file <bsd.gcc.mk> computes various parameters related to GCC 1048support libraries. It defines no targets. <bsd.own.mk> MUST be included 1049before <bsd.gcc.mk>. 1050 1051The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1052of which need to know where to find certain GCC support libraries. 1053 1054The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1055which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1056the compiler is asked where to find the support libraries, otherwise the 1057support libraries are found in ${DESTDIR}/usr/lib. 1058 1059<bsd.gcc.mk> sets the following variables: 1060 1061_GCC_CRTBEGIN The full path name to crtbegin.o. 1062 1063_GCC_CRTBEGINS The full path name to crtbeginS.o. 1064 1065_GCC_CRTEND The full path name to crtend.o. 1066 1067_GCC_CRTENDS The full path name to crtendS.o. 1068 1069_GCC_LIBGCCDIR The directory where libgcc.a is located. 1070 1071 1072=-=-=-=-= bsd.inc.mk =-=-=-=-= 1073 1074The include file <bsd.inc.mk> defines the includes target and uses the 1075variables: 1076 1077INCS The list of include files. 1078 1079INCSDIR The location to install the include files. 1080 1081INCSNAME Target name of the include file, if only one; same as 1082 FILESNAME, but for include files. 1083 1084INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1085 are installed in the 'includes' target and not the 1086 (much later) 'install' target. 1087 1088INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1089 same as FILESNAME_<file>, but for include files. 1090 1091 1092=-=-=-=-= bsd.info.mk =-=-=-=-= 1093 1094The include file <bsd.info.mk> is used to generate and install GNU Info 1095documentation from respective Texinfo source files. It defines three 1096implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1097following variables: 1098 1099TEXINFO List of Texinfo source files. Info documentation will 1100 consist of single files with the extension replaced by 1101 .info. 1102 1103INFOFLAGS Flags to pass to makeinfo. [] 1104 1105 1106=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1107 1108The include file <bsd.kernobj.mk> defines variables related to the 1109location of kernel sources and object directories. 1110 1111KERNSRCDIR Is the location of the top of the kernel src. 1112 [${_SRC_TOP_}/sys] 1113 1114KERNARCHDIR Is the location of the machine dependent kernel sources. 1115 [arch/${MACHINE}] 1116 1117KERNCONFDIR Is where the configuration files for kernels are found. 1118 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1119 1120KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1121 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1122 The default value is 1123 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1124 if it exists or the target 'obj' is being made. 1125 Otherwise the default is 1126 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1127 1128It is important that Makefiles (such as those under src/distrib) that 1129wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1130rather than make assumptions about the location of the compiled kernel. 1131 1132 1133=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1134 1135The include file <bsd.kinc.mk> defines the many targets (includes, 1136subdirectories, etc.), and is used by kernel makefiles to handle 1137include file installation. It is intended to be included alone, by 1138kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1139Please see <bsd.kinc.mk> for more details, and keep the documentation 1140in that file up to date. 1141 1142=-=-=-=-= bsd.syscall.mk =-=-=-=-= 1143 1144The include file <bsd.syscall.mk> contains the logic to create syscall 1145files for various emulations. It includes <bsd.kinc.mk> to handle the 1146rest of the targets. 1147 1148=-=-=-=-= bsd.lib.mk =-=-=-=-= 1149 1150The include file <bsd.lib.mk> has support for building libraries. It has 1151the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1152includes, install, lint, and tags. Additionally, it has a checkver target 1153which checks for installed shared object libraries whose version is greater 1154that the version of the source. It has a limited number of suffixes, 1155consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1156<bsd.shlib.mk> to get shared library parameters. 1157 1158It sets/uses the following variables: 1159 1160LIB The name of the library to build. 1161 1162LIBDIR Target directory for libraries. 1163 1164MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1165 permissions in files inside its archives to those of 1166 the file it was fed. This leads to non-reproduceable 1167 builds. If MKARZERO is set to "yes" (default is the 1168 same as MKREPRO, or "no" if MKREPRO is not defined), 1169 then the "D" flag is passed to ar, causing the 1170 timestamp, uid and gid to be zeroed and the file 1171 permissions to be set to 644. This allows .a files 1172 from different builds to be bit identical. 1173 1174SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1175 is not "no". 1176 1177SHLIB_MAJOR 1178SHLIB_MINOR 1179SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1180 1181USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1182 as the path to install shared libraries to. 1183 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1184 Default: no 1185 1186LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1187 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no 1188 MKPROFILE=no MKSTATICLIB=no". 1189 Default: no 1190 1191LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no 1192 MKPROFILE=no", and don't install the (.a) library. 1193 This is useful for "build only" helper libraries. 1194 Default: no 1195 1196LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1197 shared libraries. 1198 This is useful for C++ libraries. 1199 Default: no 1200 1201LINTLIBDIR Target directory for lint libraries. 1202 1203LIBGRP Library group. 1204 1205LIBOWN Library owner. 1206 1207LIBMODE Library mode. 1208 1209LDADD Additional loader objects. 1210 1211MAN The manual pages to be installed (use a .1 - .9 suffix). 1212 1213NOCHECKVER_<library> 1214NOCHECKVER If set, disables checking for installed shared object 1215 libraries with versions greater than the source. A 1216 particular library name, without the "lib" prefix, may 1217 be appended to the variable name to disable the check for 1218 only that library. 1219 1220SRCS List of source files to build the library. Suffix types 1221 .s, .c, and .f are supported. Note, .s files are preferred 1222 to .c files of the same name. (This is not the default for 1223 versions of make.) 1224 1225LIBDPLIBS A list of the tuples: 1226 libname path-to-srcdir-of-libname 1227 1228 For each tuple; 1229 * LIBDO.libname contains the .OBJDIR of the library 1230 `libname', and if it is not set it is determined 1231 from the srcdir and added to MAKEOVERRIDES (the 1232 latter is to allow for build time optimization). 1233 * LDADD gets -L${LIBDO.libname} -llibname added. 1234 * DPADD gets ${LIBDO.libname}/liblibname.so or 1235 ${LIBDO.libname}/liblibname.a added. 1236 1237 The special value "_external" for LIBDO.lib makes the 1238 build system to assume the library comes from outside 1239 of the NetBSD source tree and only causes -llibname 1240 to be added to LDADD. 1241 1242 This variable may be used for individual libraries, as 1243 well as in parent directories to cache common libraries 1244 as a build-time optimization. 1245 1246The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1247if it exists, as well as the include file <bsd.man.mk>. 1248 1249It has rules for building profiled objects; profiled libraries are 1250built by default. 1251 1252Libraries are ranlib'd when made. 1253 1254 1255=-=-=-=-= bsd.links.mk =-=-=-=-= 1256 1257The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1258and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 1259 1260LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1261is used. The defaults may be modified by other bsd.*.mk files which 1262include bsd.links.mk. In the future, these variables may be replaced 1263by a method for explicitly recording hard links in a metadata log. 1264 1265LINKS The list of hard links, consisting of pairs of paths: 1266 source-file target-file 1267 ${DESTDIR} is prepended to both paths before linking. 1268 For example, to link /bin/test and /bin/[, use: 1269 LINKS=/bin/test /bin/[ 1270 1271CONFIGLINKS Similar semantics to LINKS, except that the links 1272 are installed by the `configinstall' target, 1273 not the `install' target. 1274 1275SYMLINKS The list of symbolic links, consisting of pairs of paths: 1276 source-file target-file 1277 ${DESTDIR} is only prepended to target-file before linking. 1278 For example, to symlink /usr/bin/tar to /bin/tar resulting 1279 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1280 SYMLINKS=/bin/tar /usr/bin/tar 1281 1282CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1283 are installed by the `configinstall' target, 1284 not the `install' target. 1285 1286LINKSOWN Link owner. [${BINOWN}] 1287 1288LINKSGRP Link group. [${BINGRP}] 1289 1290LINKSMODE Link mode. [${NONBINMODE}] 1291 1292LINKSOWN_<fn> Link owner of the specific file <fn>. 1293 1294LINKSGRP_<fn> Link group of the specific file <fn>. 1295 1296LINKSMODE_<fn> Link mode of the specific file <fn>. 1297 1298 1299=-=-=-=-= bsd.man.mk =-=-=-=-= 1300 1301The include file <bsd.man.mk> handles installing manual pages and their 1302links. 1303 1304It has a three targets: 1305 1306 catinstall: 1307 Install the preformatted manual pages and their links. 1308 htmlinstall: 1309 Install the HTML manual pages and their links. 1310 maninstall: 1311 Install the manual page sources and their links. 1312 1313It sets/uses the following variables: 1314 1315MANDIR Base path for manual installation. 1316 1317MANGRP Manual group. 1318 1319MANOWN Manual owner. 1320 1321MANMODE Manual mode. 1322 1323MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 1324 or "/tahoe" for machine specific manual pages. 1325 1326MAN The manual pages to be installed (use a .1 - .9 suffix). 1327 1328MLINKS List of manual page links (using a .1 - .9 suffix). The 1329 linked-to file must come first, the linked file second, 1330 and there may be multiple pairs. 1331 1332The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1333it exists. 1334 1335 1336=-=-=-=-= bsd.obj.mk =-=-=-=-= 1337 1338The include file <bsd.obj.mk> defines targets related to the creation 1339and use of separated object and source directories. 1340 1341If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1342${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1343it exists. Otherwise make(1) looks for the existence of a 1344subdirectory (or a symlink to a directory) of the source directory 1345into which built targets should be placed. If an environment variable 1346named MAKEOBJDIR is set, make(1) uses its value as the name of the 1347object directory; failing that, make first looks for a subdirectory 1348named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1349 1350Object directories are not created automatically by make(1) if they 1351don't exist; you need to run a separate "make obj". (This will happen 1352during a top-level build if "MKOBJDIRS" is set to a value other than 1353"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1354and this is determined by a simple string prefix comparison -- object 1355directories are created in a separate object directory tree, and a 1356symlink to the object directory in that tree is created in the source 1357directory; otherwise, "make obj" assumes that you're not in the main 1358source tree and that it's not safe to use a separate object tree. 1359 1360Several variables used by <bsd.obj.mk> control exactly what 1361directories and links get created during a "make obj": 1362 1363MAKEOBJDIR If set, this is the component name of the object 1364 directory. 1365 1366OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1367 object directories or links named "obj.${MACHINE}"; 1368 otherwise, just creates ones named "obj". 1369 1370USR_OBJMACHINE If set, and the current directory is a subdirectory of 1371 ${BSDSRCDIR}, create object directory in the 1372 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1373 otherwise, create it in the corresponding subdirectory 1374 of ${BSDOBJDIR} 1375 1376BUILDID If set, the contents of this variable are appended 1377 to the object directory name. If OBJMACHINE is also 1378 set, ".${BUILDID}" is added after ".${MACHINE}". 1379 1380 1381=-=-=-=-= bsd.prog.mk =-=-=-=-= 1382 1383The include file <bsd.prog.mk> handles building programs from one or 1384more source files, along with their manual pages. It has a limited number 1385of suffixes, consistent with the current needs of the BSD tree. 1386<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1387 1388It has eight targets: 1389 1390 all: 1391 build the program and its manual page. This also 1392 creates a GDB initialization file (.gdbinit) in 1393 the objdir. The .gdbinit file sets the shared library 1394 prefix to ${DESTDIR} to facilitate cross-debugging. 1395 clean: 1396 remove the program, any object files and the files a.out, 1397 Errs, errs, mklog, and ${PROG}.core. 1398 cleandir: 1399 remove all of the files removed by the target clean, as 1400 well as .depend, tags, and any manual pages. 1401 `distclean' is a synonym for `cleandir'. 1402 depend: 1403 make the dependencies for the source files, and store 1404 them in the file .depend. 1405 includes: 1406 install any header files. 1407 install: 1408 install the program and its manual pages; if the Makefile 1409 does not itself define the target install, the targets 1410 beforeinstall and afterinstall may also be used to cause 1411 actions immediately before and after the install target 1412 is executed. 1413 lint: 1414 run lint on the source files 1415 tags: 1416 create a tags file for the source files. 1417 1418It sets/uses the following variables: 1419 1420BINGRP Binary group. 1421 1422BINOWN Binary owner. 1423 1424BINMODE Binary mode. 1425 1426CLEANDIRFILES Additional files to remove for the cleandir target. 1427 1428CLEANFILES Additional files to remove for the clean and cleandir targets. 1429 1430COPTS Additional flags to the compiler when creating C objects. 1431 1432COPTS.<fn> Additional flags to the compiler when creating the 1433 C objects for <fn>. 1434 For <fn>.[ly], "<fn>.c" must be used. 1435 1436CPUFLAGS Additional flags to the compiler/assembler to select 1437 CPU instruction set options, CPU tuning options, etc. 1438 1439CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1440 For <fn>.[ly], "<fn>.c" must be used. 1441 1442CPPFLAGS Additional flags to the C pre-processor. 1443 1444CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1445 For <fn>.[ly], "<fn>.c" must be used. 1446 1447GDBINIT List of GDB initialization files to add to "source" 1448 directives in the .gdbinit file that is created in the 1449 objdir. 1450 1451LDADD Additional loader objects. Usually used for libraries. 1452 For example, to load with the compatibility and utility 1453 libraries, use: 1454 1455 LDADD+=-lutil -lcompat 1456 1457LDFLAGS Additional linker flags (passed to ${CC} during link). 1458 1459LINKS See <bsd.links.mk> 1460 1461OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1462 1463OBJCOPTS.<fn> Additional flags to the compiler when creating the 1464 ObjC objects for <fn>. 1465 For <fn>.[ly], "<fn>.c" must be used. 1466 1467SYMLINKS See <bsd.links.mk> 1468 1469MAN Manual pages (should end in .1 - .9). If no MAN variable is 1470 defined, "MAN=${PROG}.1" is assumed. 1471 1472PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1473 time, with the value of this variable as args to paxctl(1). 1474 1475PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1476 1477PROG The name of the program to build. If not supplied, nothing 1478 is built. 1479 1480PROG_CXX If defined, the name of the program to build. Also 1481 causes <bsd.prog.mk> to link the program with the C++ 1482 compiler rather than the C compiler. PROG_CXX overrides 1483 the value of PROG if PROG is also set. 1484 1485PROGNAME The name that the above program will be installed as, if 1486 different from ${PROG}. 1487 1488SRCS List of source files to build the program. If SRCS is not 1489 defined, it's assumed to be ${PROG}.c. 1490 1491DPSRCS List of source files which are needed for generating 1492 dependencies, but are not needed in ${SRCS}. 1493 1494DPADD Additional dependencies for the program. Usually used for 1495 libraries. For example, to depend on the compatibility and 1496 utility libraries use: 1497 1498 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1499 1500 The following system libraries are predefined for DPADD: 1501 1502

It has the same eight targets as <bsd.prog.mk>: all, 1752clean, cleandir, depend, includes, install, lint, and tags. It uses the 1753following variables: 1754 1755NOSUBDIR If this variable is defined, then the SUBDIR variable 1756 will be ignored and subdirectories will not be processed. 1757 1758SUBDIR For all of the directories listed in ${SUBDIR}, the 1759 specified directory will be visited and the target made. 1760 1761 As a special case, the use of a token .WAIT as an 1762 entry in SUBDIR acts as a synchronization barrier 1763 when multiple make jobs are run; subdirs before the 1764 .WAIT must complete before any subdirs after .WAIT are 1765 started. See make(1) for some caveats on use of .WAIT 1766 and other special sources. 1767 1768 1769=-=-=-=-= bsd.x11.mk =-=-=-=-= 1770 1771The include file <bsd.x11.mk> contains parameters and targets for 1772cross-building X11 from ${X11SRCDIR.xc} / ${X11MITSRCDIR.*}. 1773It should be included after the general Makefile contents but before 1774the include files such as <bsd.prog.mk> and <bsd.lib.mk>. 1775 1776It provides the following targets: 1777 .man.1 .man.3 .man.4 .man.5 .man.7: 1778 If ${MAN} or ${PROG} is set and ${MKMAN} != "no", 1779 these rules convert from X11's manual page source 1780 into an mdoc.old source file. 1781 1782It sets the following variables: 1783 1784BINDIR Set to ${X11BINDIR}. 1785 To override, define after including <bsd.x11.mk> 1786 1787LIBDIR Set to ${X11USRLIBDIR}. 1788 To override, define after including <bsd.x11.mk> 1789 1790MANDIR Set to ${X11MANDIR}. 1791 To override, define after including <bsd.x11.mk> 1792 1793CPPFLAGS Appended with definitions to include from 1794 ${DESTDIR}${X11INCDIR} 1795 1796LDFLAGS Appended with definitions to link from 1797 ${DESTDIR}${X11USRLIBDIR} 1798 1799X11FLAGS.CONNECTION Equivalent to X11's CONNECTION_FLAGS. 1800 1801X11FLAGS.EXTENSION Equivalent to X11's EXT_DEFINES. 1802 1803X11FLAGS.LOADABLE Equivalent to X11's LOADABLE. 1804 1805X11FLAGS.OS_DEFINES Equivalent to X11's OS_DEFINES. 1806 1807X11FLAGS.SERVER Equivalent to X11's ServerDefines. 1808 1809X11FLAGS.THREADLIB Equivalent to X11's THREADS_DEFINES for libraries. 1810 1811X11FLAGS.THREADS Equivalent to X11's THREADS_DEFINES. 1812 1813X11FLAGS.VERSION cpp(1) definitions of OSMAJORVERSION and OSMINORVERSION. 1814 1815X11FLAGS.DIX Equivalent to X11's DIX_DEFINES. 1816 1817X11TOOL_UNXCOMM Commandline to convert `XCOMM' comments to `#' 1818 1819It uses the following variables: 1820 1821APPDEFS List of app-default files to install. 1822 1823CPPSCRIPTS List of files/scripts to run through cpp(1) 1824 and then ${X11TOOL_UNXCOMM}.
