1# $NetBSD: bsd.README,v 1.321 2013/10/28 01:47:13 mrg Exp $ 2# @(#)bsd.README 8.2 (Berkeley) 4/2/94 3 4This is the README file for the make "include" files for the NetBSD 5source tree. The files are installed in /usr/share/mk, and are, 6by convention, named with the suffix ".mk". 7 8Note, this file is not intended to replace reading through the .mk 9files for anything tricky. 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 149MKCVS If "no", don't build or install cvs(1). 150 Default: yes 151 152MKDEBUG If "no", don't build and install separate debugging symbols 153 into /usr/libdata/debug. 154 Default: no 155 156MKDEBUGLIB Build *_g.a debugging libraries, which are compiled 157 with -DDEBUG. 158 Default: no 159 160MKDEPINCLUDES If "yes" issue .include statements in the .depend file 161 instead of inlining the contents of the .d files. Useful 162 when stale dependencies are present, to list the exact 163 files that need refreshing. It is off by default because 164 it is possibly slower. 165 Default "no" 166 167MKDOC If "no", don't build or install the documentation. 168 Default: yes 169 170MKDTRACE If "no", do not build and install the kernel modules, 171 utilities and libraries used to implement the dtrace(1) 172 facility. 173 Default: no 174 175MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 176 don't install certain libraries in /lib, and don't 177 install the shared linker into /libexec. 178 Default: yes 179 180MKEXTSRC If not "no", 'make build' also descends into either src/extsrc 181 to cross-build programs and libraries externally added by 182 users, and automatically enables creation of those sets. 183 Default: no 184 185MKGCC If "no", don't build gcc(1) or any of the GCC-related 186 libraries (libgcc, libobjc, libstdc++). 187 Default: yes 188 189MKGCCCMDS If "no", don't build gcc(1), but do build the GCC-related 190 libraries (libgcc, libobjc, libstdc++). 191 Default: yes 192 193MKGDB If "no", don't build gdb(1). 194 Default: yes 195 196MKHESIOD If "no", disables building of Hesiod infrastructure 197 (libraries and support programs). 198 Default: yes 199 200MKHOSTOBJ If not "no", for programs intended to be run on the compile 201 host, the name, release, and architecture of the host 202 operating system will be suffixed to the name of the object 203 directory created by "make obj". 204 Default: no 205 206MKHTML If "no", don't build or install the HTML man pages. 207 Default: yes 208 209MKIEEEFP If "no", don't add code for IEEE754/IEC60559 conformance. 210 Has no effect on most platforms. 211 Default: yes 212 213MKSTRIPIDENT Strip the RCS IDs from program binaries and shared libraries. 214 Default: no 215 216MKINET6 If "no", disables building of INET6 (IPv6) infrastructure 217 (libraries and support programs).

The 449 stack protection code imposes a performance penalty 450 of about 5%. 451 Default: "no", unless "USE_FORT" is set to "yes" 452 453USE_FORT If "yes" turns on substitute wrappers for commonly used 454 functions that do not do bounds checking regularly, but 455 they could in some cases by using the gcc 456 __builtin_object_size() function to determine the buffer 457 size where it is known and detect buffer overflows. 458 These substitute functions are in /usr/include/ssp. 459 Default: depends on the part of the source tree 460 461USE_YP If "no", disables building YP (NIS) support into 462 various system utilities/libraries that support it. 463 If ${MKYP} is "no", USE_YP will also be forced to "no". 464 465USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 466 Otherwise, build tools/pigz and use nbpigz to compress 467 things. 468 Default: "no". 469 470X11FLAVOUR Set to "Xorg" or "XFree86", depending on whether to build 471 XFree86 or modular Xorg. Only matters if MKX11!=no. 472 Default: "Xorg" on amd64, i386, macppc, shark and sparc64, 473 "XFree86" on everything else. 474 475COPTS.lib<lib> 476OBJCOPTS.lib<lib> 477LDADD.lib<lib> 478CPPFLAGS.lib<lib> 479CXXFLAGS.lib<lib> 480COPTS.<prog> 481OBJCCOPTS.<prog> 482LDADD.<prog> 483CPPFLAGS.<prog> 484CXXFLAGS.<prog> These provide a way to specify additions to the associated 485 variables in a way that applies only to a particular library 486 or program. <lib> corresponds to the LIB variable set in 487 the library's makefile. <prog> corresponds to either PROG 488 or PROG_CXX (if set). For example, if COPTS.libcrypto is 489 set to "-g", "-g" will be added to COPTS only when compiling 490 the crypto library. 491 492The active compiler is selected using the following variables: 493AVAILABLE_COMPILER 494 List of available compiler suites. Processed in order 495 for selecting the active compiler for each frontend. 496HAVE_PCC If defined, PCC is present and enabled. 497HAVE_LLVM If defined, LLVM/Clang is present and enabled. 498UNSUPPORTED_COMPILER.xxx 499 If defined, the support for compiler "xxx" is disabled. 500 501For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 502ACTIVE_CC Active compile suite for the CC frontend. 503SUPPORTED_CC Compile suite with support for the CC frontend. 504TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 505 506=-=-=-=-= sys.mk =-=-=-=-= 507 508The include file <sys.mk> has the default rules for all makes, in the BSD 509environment or otherwise. You probably don't want to touch this file. 510 511=-=-=-=-= bsd.own.mk =-=-=-=-= 512 513The include file <bsd.own.mk> contains source tree configuration parameters, 514such as the owners, groups, etc. for both manual pages and binaries, and 515a few global "feature configuration" parameters. 516 517It has no targets. 518 519To get system-specific configuration parameters, <bsd.own.mk> will try to 520include the file specified by the "MAKECONF" variable. If MAKECONF is not 521set, or no such file exists, the system make configuration file, /etc/mk.conf 522is included. These files may define any of the variables described below. 523 524<bsd.own.mk> sets the following variables, if they are not already defined 525(defaults are in brackets): 526 527NETBSDSRCDIR Top of the NetBSD source tree. 528 If _SRC_TOP_ != "", that will be used as the default, 529 otherwise BSDSRCDIR will be used as the default. 530 Various makefiles within the NetBSD source tree will 531 use this to reference the top level of the source tree. 532 533_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 534 based on the presence of tools/ and build.sh. This variable 535 is "internal" to <bsd.own.mk>, although its value is only 536 determined once and then propagated to all sub-makes. 537 538_NETBSD_VERSION_DEPENDS 539 A list of files which contain information about 540 the version of the NetBSD being built. This is 541 defined only if the current directory appears 542 to be inside a NetBSD source tree. The list of 543 files includes ${NETBSDSRCDIR}/sys/sys/param.h 544 (which contains the kernel version number), 545 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 546 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 547 interpret the information in sys/sys/param.h), and 548 ${_SRC_TOP_OBJ_}/params (which is an optional file, 549 created by "make build" in ${_SRC_TOP_}/Makefile, 550 containing all the variables that may influence the 551 build). 552 553 Targets that depend on the NetBSD version, or on 554 variables defined at build time, can declare a 555 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 556 557 version.c: ${_NETBSD_VERSION_DEPENDS} 558 commands to create version.c 559 560BSDSRCDIR The real path to the system sources, so that 'make obj' 561 will work correctly.

[] 652 653COPY The flag passed to the install program to cause the binary 654 to be copied rather than moved. This is to be used when 655 building our own install script so that the entire system 656 can either be installed with copies, or with moves using 657 a single knob.

[${MACHINE}] 677 678Additionally, the following variables may be set by <bsd.own.mk> or in a 679make configuration file to modify the behavior of the system build 680process (default values are in brackets along with comments, if set by 681<bsd.own.mk>): 682 683USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 684 be used as part of a build in progress. 685 Supported values: 686 687 yes Use the tools from TOOLDIR. 688 Must be set to this if cross-compiling. 689 690 no Do not use the tools from TOOLDIR, but refuse to 691 build native compilation tool components that are 692 version-specific for that tool. 693 694 never Do not use the tools from TOOLDIR, even when 695 building native tool components. This is similar to 696 the traditional NetBSD build method, but does not 697 verify that the compilation tools in use are 698 up-to-date enough in order to build the tree 699 successfully. This may cause build or runtime 700 problems when building the whole NetBSD source tree. 701 702 Default: "yes" if building all or part of a whole NetBSD 703 source tree (detected automatically); "no" otherwise 704 (to preserve traditional semantics of the <bsd.*.mk> 705 make(1) include files). 706 707OBJECT_FMT Object file format. [set to "ELF" on architectures that 708 use ELF -- currently all architectures]. 709 710TOOLCHAIN_MISSING 711 If not "no", this indicates that the platform being built 712 does not have a working in-tree toolchain. If the 713 ${MACHINE_ARCH} in question falls into this category, 714 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 715 Otherwise, the variable is unconditionally assigned the 716 value "no". 717 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 718 unconditionally assigned the value "no". 719 720EXTERNAL_TOOLCHAIN 721 This variable is not directly set by <bsd.own.mk>, but 722 including <bsd.own.mk> is the canonical way to gain 723 access to this variable. The variable should be defined 724 either in the user's environment or in the user's mk.conf 725 file. If defined, this variable indicates the root of 726 an external toolchain which will be used to build the 727 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 728 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 729 cross-compile framework. 730 731 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 732 assigned the value "no", since the external version of the 733 compiler may not be able to build the library components of 734 the in-tree compiler. 735 736 NOTE: This variable is not yet used in as many places as 737 it should be. Expect the exact semantics of this variable 738 to change in the short term as parts of the cross-compile 739 framework continue to be cleaned up. 740 741The following variables are defined to commands to perform the 742appropriate operation, with the default in [brackets].

[zic] 882 883<bsd.own.mk> is generally useful when building your own Makefiles so that 884they use the same default owners etc. as the rest of the tree. 885 886 887=-=-=-=-= bsd.clean.mk =-=-=-=-= 888 889The include file <bsd.clean.mk> defines the clean and cleandir 890targets. It uses the following variables: 891 892CLEANFILES Files to remove for both the clean and cleandir targets. 893 894CLEANDIRFILES Files to remove for the cleandir target, but not for 895 the clean target. 896 897MKCLEANSRC Controls whether or not the clean and cleandir targets 898 will delete files from both the object directory, 899 ${.OBJDIR}, and the source directory, ${.CURDIR}. 900 901 If MKCLEANSRC is set to "no", then the file names in 902 CLEANFILES or CLEANDIRFILES are interpreted relative 903 to the object directory, ${.OBJDIR}. This is the 904 traditional behaviour. 905 906 If MKCLEANSRC is set to "yes", then the file deletion 907 is performed relative to both the object directory, 908 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 909 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 910 Deleting files from ${.CURDIR} is intended to remove 911 stray output files that had been left in the source 912 directory by an earlier build that did not use object 913 directories. 914 915 The default is MKCLEANSRC=yes. If you always build with 916 separate object directories, and you are sure that there 917 are no stray files in the source directories, then you 918 may set MKCLEANSRC=no to save some time. 919 920MKCLEANVERIFY Controls whether or not the clean and cleandir targets 921 will verify that files have been deleted. 922 923 If MKCLEANVERIFY is set to "no", then the files will 924 be deleted using a "rm -f" command, and its success or 925 failure will be ignored. 926 927 If MKCLEANVERIFY is set to "yes", then the success of 928 the "rm -f" command will be verified using an "ls" 929 command. 930 931 The default is MKCLEANVERIFY=yes. If you are sure that 932 there will be no problems caused by file permissions, 933 read-only file systems, or the like, then you may set 934 MKCLEANVERIFY=no to save some time. 935 936To use the clean and cleandir targets defined in <bsd.clean.mk>, other 937Makefiles or bsd.*.mk files should append file names to the CLEANFILES 938or CLEANDIRFILES variables. For example: 939 940 CLEANFILES+= a.out 941 CLEANDIRFILES+= .depend 942 943 .include <bsd.clean.mk> 944 945The files listed in CLEANFILES and CLEANDIRFILES must not be 946directories, because the potential risk from running "rm -rf" commands 947in bsd.clean.mk is considered too great. If you want to recursively 948delete a directory as part of "make clean" or "make cleandir" then you 949need to provide your own target. 950 951=-=-=-=-= bsd.dep.mk =-=-=-=-= 952 953The include file <bsd.dep.mk> contains the default targets for building 954.depend files. It creates .d files from entries in SRCS and DPSRCS 955that are C, C++, or Objective C source files, and builds .depend from the 956.d files. All other files in SRCS and all of DPSRCS will be used as 957dependencies for the .d files. In order for this to function correctly, 958it should be .included after all other .mk files and directives that may 959modify SRCS or DPSRCS. It uses the following variables: 960 961SRCS List of source files to build the program. 962 963DPSRCS List of source files which are needed for generating 964 dependencies, but are not needed in ${SRCS}. 965 966 967=-=-=-=-= bsd.files.mk =-=-=-=-= 968 969The include file <bsd.files.mk> handles the FILES variables and is included 970from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 971 972FILES The list of files to install. 973 974CONFIGFILES Similar semantics to FILES, except that the files 975 are installed by the `configinstall' target, 976 not the `install' target. 977 The FILES* variables documented below also apply. 978 979FILESOWN File owner. [${BINOWN}] 980 981FILESGRP File group. [${BINGRP}] 982 983FILESMODE File mode. [${NONBINMODE}] 984 985FILESDIR The location to install the files. 986 987FILESNAME Optional name to install each file as. 988 989FILESOWN_<fn> File owner of the specific file <fn>. 990 991FILESGRP_<fn> File group of the specific file <fn>. 992 993FILESMODE_<fn> File mode of the specific file <fn>. 994 995FILESDIR_<fn> The location to install the specific file <fn>. 996 997FILESNAME_<fn> Optional name to install <fn> as. 998 999FILESBUILD If this variable is defined, then its value will be 1000 used as the default for all FILESBUILD_<fn> variables. 1001 Otherwise, the default will be "no". 1002 1003FILESBUILD_<fn> A value different from "no" will add the file to the list of 1004 targets to be built by `realall'. Users of that variable 1005 should provide a target to build the file. 1006 1007 1008BUILDSYMLINKS List of two word items: 1009 lnsrc lntgt 1010 For each lnsrc item, create a symlink named lntgt. 1011 The lntgt symlinks are removed by the cleandir target. 1012 1013UUDECODE_FILES List of files which are stored as <file>.uue in the source 1014 tree. Each one will be decoded with ${TOOL_UUDECODE}. 1015 The source files have a `.uue' suffix, the generated files do 1016 not. 1017 1018UUDECODE_FILES_RENAME_<fn> 1019 Rename the output from the decode to the provided name. 1020 1021 *NOTE: These files are simply decoded, with no install or other 1022 rule applying implicitly except being added to the clean 1023 target. 1024 1025=-=-=-=-= bsd.gcc.mk =-=-=-=-= 1026 1027The include file <bsd.gcc.mk> computes various parameters related to GCC 1028support libraries. It defines no targets. <bsd.own.mk> MUST be included 1029before <bsd.gcc.mk>. 1030 1031The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1032of which need to know where to find certain GCC support libraries. 1033 1034The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1035which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1036the compiler is asked where to find the support libraries, otherwise the 1037support libraries are found in ${DESTDIR}/usr/lib. 1038 1039<bsd.gcc.mk> sets the following variables: 1040 1041_GCC_CRTBEGIN The full path name to crtbegin.o. 1042 1043_GCC_CRTBEGINS The full path name to crtbeginS.o. 1044 1045_GCC_CRTEND The full path name to crtend.o. 1046 1047_GCC_CRTENDS The full path name to crtendS.o. 1048 1049_GCC_LIBGCCDIR The directory where libgcc.a is located. 1050 1051 1052=-=-=-=-= bsd.inc.mk =-=-=-=-= 1053 1054The include file <bsd.inc.mk> defines the includes target and uses the 1055variables: 1056 1057INCS The list of include files. 1058 1059INCSDIR The location to install the include files. 1060 1061INCSNAME Target name of the include file, if only one; same as 1062 FILESNAME, but for include files. 1063 1064INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1065 are installed in the 'includes' target and not the 1066 (much later) 'install' target. 1067 1068INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1069 same as FILESNAME_<file>, but for include files. 1070 1071 1072=-=-=-=-= bsd.info.mk =-=-=-=-= 1073 1074The include file <bsd.info.mk> is used to generate and install GNU Info 1075documentation from respective Texinfo source files. It defines three 1076implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1077following variables: 1078 1079TEXINFO List of Texinfo source files. Info documentation will 1080 consist of single files with the extension replaced by 1081 .info. 1082 1083INFOFLAGS Flags to pass to makeinfo. [] 1084 1085 1086=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1087 1088The include file <bsd.kernobj.mk> defines variables related to the 1089location of kernel sources and object directories. 1090 1091KERNSRCDIR Is the location of the top of the kernel src. 1092 [${_SRC_TOP_}/sys] 1093 1094KERNARCHDIR Is the location of the machine dependent kernel sources. 1095 [arch/${MACHINE}] 1096 1097KERNCONFDIR Is where the configuration files for kernels are found. 1098 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1099 1100KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1101 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1102 The default value is 1103 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1104 if it exists or the target 'obj' is being made. 1105 Otherwise the default is 1106 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1107 1108It is important that Makefiles (such as those under src/distrib) that 1109wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1110rather than make assumptions about the location of the compiled kernel. 1111 1112 1113=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1114 1115The include file <bsd.kinc.mk> defines the many targets (includes, 1116subdirectories, etc.), and is used by kernel makefiles to handle 1117include file installation. It is intended to be included alone, by 1118kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1119Please see <bsd.kinc.mk> for more details, and keep the documentation 1120in that file up to date. 1121 1122 1123=-=-=-=-= bsd.lib.mk =-=-=-=-= 1124 1125The include file <bsd.lib.mk> has support for building libraries. It has 1126the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1127includes, install, lint, and tags. Additionally, it has a checkver target 1128which checks for installed shared object libraries whose version is greater 1129that the version of the source. It has a limited number of suffixes, 1130consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1131<bsd.shlib.mk> to get shared library parameters. 1132 1133It sets/uses the following variables: 1134 1135LIB The name of the library to build. 1136 1137LIBDIR Target directory for libraries. 1138 1139MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1140 permissions in files inside its archives to those of 1141 the file it was fed. This leads to non-reproduceable 1142 builds. If MKARZERO is set to "yes" (default is "no") 1143 then the "D" flag is passed to ar, causing the 1144 timestamp, uid and gid to be zeroed and the file 1145 permissions to be set to 644. This allows .a files 1146 from different builds to be bit identical. 1147 1148SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1149 is not "no". 1150 1151SHLIB_MAJOR 1152SHLIB_MINOR 1153SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1154 1155USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1156 as the path to install shared libraries to. 1157 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1158 Default: no 1159 1160LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1161 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no 1162 MKPROFILE=no MKSTATICLIB=no". 1163 Default: no 1164 1165LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no 1166 MKPROFILE=no", and don't install the (.a) library. 1167 This is useful for "build only" helper libraries. 1168 Default: no 1169 1170LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1171 shared libraries. 1172 This is useful for C++ libraries. 1173 Default: no 1174 1175LINTLIBDIR Target directory for lint libraries. 1176 1177LIBGRP Library group. 1178 1179LIBOWN Library owner. 1180 1181LIBMODE Library mode. 1182 1183LDADD Additional loader objects. 1184 1185MAN The manual pages to be installed (use a .1 - .9 suffix). 1186 1187NOCHECKVER_<library> 1188NOCHECKVER If set, disables checking for installed shared object 1189 libraries with versions greater than the source. A 1190 particular library name, without the "lib" prefix, may 1191 be appended to the variable name to disable the check for 1192 only that library. 1193 1194SRCS List of source files to build the library. Suffix types 1195 .s, .c, and .f are supported. Note, .s files are preferred 1196 to .c files of the same name. (This is not the default for 1197 versions of make.) 1198 1199LIBDPLIBS A list of the tuples: 1200 libname path-to-srcdir-of-libname 1201 1202 For each tuple; 1203 * LIBDO.libname contains the .OBJDIR of the library 1204 `libname', and if it is not set it is determined 1205 from the srcdir and added to MAKEOVERRIDES (the 1206 latter is to allow for build time optimization). 1207 * LDADD gets -L${LIBDO.libname} -llibname added. 1208 * DPADD gets ${LIBDO.libname}/liblibname.so or 1209 ${LIBDO.libname}/liblibname.a added. 1210 1211 The special value "_external" for LIBDO.lib makes the 1212 build system to assume the library comes from outside 1213 of the NetBSD source tree and only causes -llibname 1214 to be added to LDADD. 1215 1216 This variable may be used for individual libraries, as 1217 well as in parent directories to cache common libraries 1218 as a build-time optimization. 1219 1220The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1221if it exists, as well as the include file <bsd.man.mk>. 1222 1223It has rules for building profiled objects; profiled libraries are 1224built by default. 1225 1226Libraries are ranlib'd when made. 1227 1228 1229=-=-=-=-= bsd.links.mk =-=-=-=-= 1230 1231The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1232and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 1233 1234LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1235is used. The defaults may be modified by other bsd.*.mk files which 1236include bsd.links.mk. In the future, these variables may be replaced 1237by a method for explicitly recording hard links in a metadata log. 1238 1239LINKS The list of hard links, consisting of pairs of paths: 1240 source-file target-file 1241 ${DESTDIR} is prepended to both paths before linking. 1242 For example, to link /bin/test and /bin/[, use: 1243 LINKS=/bin/test /bin/[ 1244 1245CONFIGLINKS Similar semantics to LINKS, except that the links 1246 are installed by the `configinstall' target, 1247 not the `install' target. 1248 1249SYMLINKS The list of symbolic links, consisting of pairs of paths: 1250 source-file target-file 1251 ${DESTDIR} is only prepended to target-file before linking. 1252 For example, to symlink /usr/bin/tar to /bin/tar resulting 1253 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1254 SYMLINKS=/bin/tar /usr/bin/tar 1255 1256CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1257 are installed by the `configinstall' target, 1258 not the `install' target. 1259 1260LINKSOWN Link owner. [${BINOWN}] 1261 1262LINKSGRP Link group. [${BINGRP}] 1263 1264LINKSMODE Link mode. [${NONBINMODE}] 1265 1266LINKSOWN_<fn> Link owner of the specific file <fn>. 1267 1268LINKSGRP_<fn> Link group of the specific file <fn>. 1269 1270LINKSMODE_<fn> Link mode of the specific file <fn>. 1271 1272 1273=-=-=-=-= bsd.man.mk =-=-=-=-= 1274 1275The include file <bsd.man.mk> handles installing manual pages and their 1276links. 1277 1278It has a three targets: 1279 1280 catinstall: 1281 Install the preformatted manual pages and their links. 1282 htmlinstall: 1283 Install the HTML manual pages and their links. 1284 maninstall: 1285 Install the manual page sources and their links. 1286 1287It sets/uses the following variables: 1288 1289MANDIR Base path for manual installation. 1290 1291MANGRP Manual group. 1292 1293MANOWN Manual owner. 1294 1295MANMODE Manual mode. 1296 1297MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 1298 or "/tahoe" for machine specific manual pages. 1299 1300MAN The manual pages to be installed (use a .1 - .9 suffix). 1301 1302MLINKS List of manual page links (using a .1 - .9 suffix). The 1303 linked-to file must come first, the linked file second, 1304 and there may be multiple pairs. 1305 1306The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1307it exists. 1308 1309 1310=-=-=-=-= bsd.obj.mk =-=-=-=-= 1311 1312The include file <bsd.obj.mk> defines targets related to the creation 1313and use of separated object and source directories. 1314 1315If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1316${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1317it exists. Otherwise make(1) looks for the existence of a 1318subdirectory (or a symlink to a directory) of the source directory 1319into which built targets should be placed. If an environment variable 1320named MAKEOBJDIR is set, make(1) uses its value as the name of the 1321object directory; failing that, make first looks for a subdirectory 1322named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1323 1324Object directories are not created automatically by make(1) if they 1325don't exist; you need to run a separate "make obj". (This will happen 1326during a top-level build if "MKOBJDIRS" is set to a value other than 1327"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1328and this is determined by a simple string prefix comparison -- object 1329directories are created in a separate object directory tree, and a 1330symlink to the object directory in that tree is created in the source 1331directory; otherwise, "make obj" assumes that you're not in the main 1332source tree and that it's not safe to use a separate object tree. 1333 1334Several variables used by <bsd.obj.mk> control exactly what 1335directories and links get created during a "make obj": 1336 1337MAKEOBJDIR If set, this is the component name of the object 1338 directory. 1339 1340OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1341 object directories or links named "obj.${MACHINE}"; 1342 otherwise, just creates ones named "obj". 1343 1344USR_OBJMACHINE If set, and the current directory is a subdirectory of 1345 ${BSDSRCDIR}, create object directory in the 1346 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1347 otherwise, create it in the corresponding subdirectory 1348 of ${BSDOBJDIR} 1349 1350BUILDID If set, the contents of this variable are appended 1351 to the object directory name. If OBJMACHINE is also 1352 set, ".${BUILDID}" is added after ".${MACHINE}". 1353 1354 1355=-=-=-=-= bsd.prog.mk =-=-=-=-= 1356 1357The include file <bsd.prog.mk> handles building programs from one or 1358more source files, along with their manual pages. It has a limited number 1359of suffixes, consistent with the current needs of the BSD tree. 1360<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1361 1362It has eight targets: 1363 1364 all: 1365 build the program and its manual page. This also 1366 creates a GDB initialization file (.gdbinit) in 1367 the objdir. The .gdbinit file sets the shared library 1368 prefix to ${DESTDIR} to facilitate cross-debugging. 1369 clean: 1370 remove the program, any object files and the files a.out, 1371 Errs, errs, mklog, and ${PROG}.core. 1372 cleandir: 1373 remove all of the files removed by the target clean, as 1374 well as .depend, tags, and any manual pages. 1375 `distclean' is a synonym for `cleandir'. 1376 depend: 1377 make the dependencies for the source files, and store 1378 them in the file .depend. 1379 includes: 1380 install any header files. 1381 install: 1382 install the program and its manual pages; if the Makefile 1383 does not itself define the target install, the targets 1384 beforeinstall and afterinstall may also be used to cause 1385 actions immediately before and after the install target 1386 is executed. 1387 lint: 1388 run lint on the source files 1389 tags: 1390 create a tags file for the source files. 1391 1392It sets/uses the following variables: 1393 1394BINGRP Binary group. 1395 1396BINOWN Binary owner. 1397 1398BINMODE Binary mode. 1399 1400CLEANDIRFILES Additional files to remove for the cleandir target. 1401 1402CLEANFILES Additional files to remove for the clean and cleandir targets. 1403 1404COPTS Additional flags to the compiler when creating C objects. 1405 1406COPTS.<fn> Additional flags to the compiler when creating the 1407 C objects for <fn>. 1408 For <fn>.[ly], "<fn>.c" must be used. 1409 1410CPUFLAGS Additional flags to the compiler/assembler to select 1411 CPU instruction set options, CPU tuning options, etc. 1412 1413CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1414 For <fn>.[ly], "<fn>.c" must be used. 1415 1416CPPFLAGS Additional flags to the C pre-processor. 1417 1418CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1419 For <fn>.[ly], "<fn>.c" must be used. 1420 1421GDBINIT List of GDB initialization files to add to "source" 1422 directives in the .gdbinit file that is created in the 1423 objdir. 1424 1425LDADD Additional loader objects. Usually used for libraries. 1426 For example, to load with the compatibility and utility 1427 libraries, use: 1428 1429 LDADD+=-lutil -lcompat 1430 1431LDFLAGS Additional linker flags (passed to ${CC} during link). 1432 1433LINKS See <bsd.links.mk> 1434 1435OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1436 1437OBJCOPTS.<fn> Additional flags to the compiler when creating the 1438 ObjC objects for <fn>. 1439 For <fn>.[ly], "<fn>.c" must be used. 1440 1441SYMLINKS See <bsd.links.mk> 1442 1443MAN Manual pages (should end in .1 - .9). If no MAN variable is 1444 defined, "MAN=${PROG}.1" is assumed. 1445 1446PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1447 time, with the value of this variable as args to paxctl(1). 1448 1449PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1450 1451PROG The name of the program to build. If not supplied, nothing 1452 is built. 1453 1454PROG_CXX If defined, the name of the program to build. Also 1455 causes <bsd.prog.mk> to link the program with the C++ 1456 compiler rather than the C compiler. PROG_CXX overrides 1457 the value of PROG if PROG is also set. 1458 1459PROGNAME The name that the above program will be installed as, if 1460 different from ${PROG}. 1461 1462SRCS List of source files to build the program. If SRCS is not 1463 defined, it's assumed to be ${PROG}.c. 1464 1465DPSRCS List of source files which are needed for generating 1466 dependencies, but are not needed in ${SRCS}. 1467 1468DPADD Additional dependencies for the program. Usually used for 1469 libraries. For example, to depend on the compatibility and 1470 utility libraries use: 1471 1472 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1473 1474 The following system libraries are predefined for DPADD: 1475 1476

It defines no targets. <bsd.own.mk> MUST be 1698included before <bsd.shlib.mk>. 1699 1700<bsd.own.mk> sets the following variables, if they are not already defined 1701(defaults are in brackets): 1702 1703SHLIBINSTALLDIR If ${USE_SHLIBDIR} is not "no", use ${SHLIBINSTALLDIR} 1704 instead of ${LIBDIR} as the base path for shared library 1705 installation. [/lib] 1706 1707SHLIBDIR The path to USE_SHLIBDIR shared libraries to use when building 1708 a program. [/lib for programs in /bin and /sbin, /usr/lib 1709 for all others.] 1710 1711_LIBSODIR Set to ${SHLIBINSTALLDIR} if ${USE_SHLIBDIR} is not "no", 1712 otherwise set to ${LIBDIR} 1713 1714SHLINKINSTALLDIR Base path for shared linker.

It has the same eight targets as <bsd.prog.mk>: all, 1725clean, cleandir, depend, includes, install, lint, and tags. It uses the 1726following variables: 1727 1728NOSUBDIR If this variable is defined, then the SUBDIR variable 1729 will be ignored and subdirectories will not be processed. 1730 1731SUBDIR For all of the directories listed in ${SUBDIR}, the 1732 specified directory will be visited and the target made. 1733 1734 As a special case, the use of a token .WAIT as an 1735 entry in SUBDIR acts as a synchronization barrier 1736 when multiple make jobs are run; subdirs before the 1737 .WAIT must complete before any subdirs after .WAIT are 1738 started. See make(1) for some caveats on use of .WAIT 1739 and other special sources. 1740 1741 1742=-=-=-=-= bsd.sys.mk =-=-=-=-= 1743 1744The include file <bsd.sys.mk> is used by <bsd.prog.mk> and 1745<bsd.lib.mk>.
