1# $NetBSD: bsd.README,v 1.326 2014/01/16 01:19:46 christos 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.

This is to be used when building your 650 own install script so that the entire system can be made 651 stripped/not-stripped using a single knob. [] 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. [-c] 658 659MAKEDIRTARGETENV 660 Environment variables passed to the child make process 661 invoked by MAKEDIRTARGET. 662 663MAKEDIRTARGET dir target [params] 664 Runs "cd $${dir} && ${MAKE} [params] $${target}", 665 displaying a "pretty" message whilst doing so. 666 667RELEASEMACHINEDIR 668 Subdirectory used below RELEASEDIR when building 669 a release.

[${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].

This keeps those definitions in 885centralized place. 886 887<bsd.own.mk> is generally useful when building your own Makefiles so that 888they use the same default owners etc. as the rest of the tree. 889 890 891=-=-=-=-= bsd.clean.mk =-=-=-=-= 892 893The include file <bsd.clean.mk> defines the clean and cleandir 894targets. It uses the following variables: 895 896CLEANFILES Files to remove for both the clean and cleandir targets. 897 898CLEANDIRFILES Files to remove for the cleandir target, but not for 899 the clean target. 900 901MKCLEANSRC Controls whether or not the clean and cleandir targets 902 will delete files from both the object directory, 903 ${.OBJDIR}, and the source directory, ${.CURDIR}. 904 905 If MKCLEANSRC is set to "no", then the file names in 906 CLEANFILES or CLEANDIRFILES are interpreted relative 907 to the object directory, ${.OBJDIR}. This is the 908 traditional behaviour. 909 910 If MKCLEANSRC is set to "yes", then the file deletion 911 is performed relative to both the object directory, 912 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 913 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 914 Deleting files from ${.CURDIR} is intended to remove 915 stray output files that had been left in the source 916 directory by an earlier build that did not use object 917 directories. 918 919 The default is MKCLEANSRC=yes. If you always build with 920 separate object directories, and you are sure that there 921 are no stray files in the source directories, then you 922 may set MKCLEANSRC=no to save some time. 923 924MKCLEANVERIFY Controls whether or not the clean and cleandir targets 925 will verify that files have been deleted. 926 927 If MKCLEANVERIFY is set to "no", then the files will 928 be deleted using a "rm -f" command, and its success or 929 failure will be ignored. 930 931 If MKCLEANVERIFY is set to "yes", then the success of 932 the "rm -f" command will be verified using an "ls" 933 command. 934 935 The default is MKCLEANVERIFY=yes. If you are sure that 936 there will be no problems caused by file permissions, 937 read-only file systems, or the like, then you may set 938 MKCLEANVERIFY=no to save some time. 939 940To use the clean and cleandir targets defined in <bsd.clean.mk>, other 941Makefiles or bsd.*.mk files should append file names to the CLEANFILES 942or CLEANDIRFILES variables. For example: 943 944 CLEANFILES+= a.out 945 CLEANDIRFILES+= .depend 946 947 .include <bsd.clean.mk> 948 949The files listed in CLEANFILES and CLEANDIRFILES must not be 950directories, because the potential risk from running "rm -rf" commands 951in bsd.clean.mk is considered too great. If you want to recursively 952delete a directory as part of "make clean" or "make cleandir" then you 953need to provide your own target. 954 955=-=-=-=-= bsd.dep.mk =-=-=-=-= 956 957The include file <bsd.dep.mk> contains the default targets for building 958.depend files. It creates .d files from entries in SRCS and DPSRCS 959that are C, C++, or Objective C source files, and builds .depend from the 960.d files. All other files in SRCS and all of DPSRCS will be used as 961dependencies for the .d files. In order for this to function correctly, 962it should be .included after all other .mk files and directives that may 963modify SRCS or DPSRCS. It uses the following variables: 964 965SRCS List of source files to build the program. 966 967DPSRCS List of source files which are needed for generating 968 dependencies, but are not needed in ${SRCS}. 969 970 971=-=-=-=-= bsd.files.mk =-=-=-=-= 972 973The include file <bsd.files.mk> handles the FILES variables and is included 974from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 975 976FILES The list of files to install. 977 978CONFIGFILES Similar semantics to FILES, except that the files 979 are installed by the `configinstall' target, 980 not the `install' target. 981 The FILES* variables documented below also apply. 982 983FILESOWN File owner. [${BINOWN}] 984 985FILESGRP File group. [${BINGRP}] 986 987FILESMODE File mode. [${NONBINMODE}] 988 989FILESDIR The location to install the files. 990 991FILESNAME Optional name to install each file as. 992 993FILESOWN_<fn> File owner of the specific file <fn>. 994 995FILESGRP_<fn> File group of the specific file <fn>. 996 997FILESMODE_<fn> File mode of the specific file <fn>. 998 999FILESDIR_<fn> The location to install the specific file <fn>. 1000 1001FILESNAME_<fn> Optional name to install <fn> as. 1002 1003FILESBUILD If this variable is defined, then its value will be 1004 used as the default for all FILESBUILD_<fn> variables. 1005 Otherwise, the default will be "no". 1006 1007FILESBUILD_<fn> A value different from "no" will add the file to the list of 1008 targets to be built by `realall'. Users of that variable 1009 should provide a target to build the file. 1010 1011 1012BUILDSYMLINKS List of two word items: 1013 lnsrc lntgt 1014 For each lnsrc item, create a symlink named lntgt. 1015 The lntgt symlinks are removed by the cleandir target. 1016 1017UUDECODE_FILES List of files which are stored as <file>.uue in the source 1018 tree. Each one will be decoded with ${TOOL_UUDECODE}. 1019 The source files have a `.uue' suffix, the generated files do 1020 not. 1021 1022UUDECODE_FILES_RENAME_<fn> 1023 Rename the output from the decode to the provided name. 1024 1025 *NOTE: These files are simply decoded, with no install or other 1026 rule applying implicitly except being added to the clean 1027 target. 1028 1029=-=-=-=-= bsd.gcc.mk =-=-=-=-= 1030 1031The include file <bsd.gcc.mk> computes various parameters related to GCC 1032support libraries. It defines no targets. <bsd.own.mk> MUST be included 1033before <bsd.gcc.mk>. 1034 1035The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1036of which need to know where to find certain GCC support libraries. 1037 1038The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1039which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1040the compiler is asked where to find the support libraries, otherwise the 1041support libraries are found in ${DESTDIR}/usr/lib. 1042 1043<bsd.gcc.mk> sets the following variables: 1044 1045_GCC_CRTBEGIN The full path name to crtbegin.o. 1046 1047_GCC_CRTBEGINS The full path name to crtbeginS.o. 1048 1049_GCC_CRTEND The full path name to crtend.o. 1050 1051_GCC_CRTENDS The full path name to crtendS.o. 1052 1053_GCC_LIBGCCDIR The directory where libgcc.a is located. 1054 1055 1056=-=-=-=-= bsd.inc.mk =-=-=-=-= 1057 1058The include file <bsd.inc.mk> defines the includes target and uses the 1059variables: 1060 1061INCS The list of include files. 1062 1063INCSDIR The location to install the include files. 1064 1065INCSNAME Target name of the include file, if only one; same as 1066 FILESNAME, but for include files. 1067 1068INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1069 are installed in the 'includes' target and not the 1070 (much later) 'install' target. 1071 1072INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1073 same as FILESNAME_<file>, but for include files. 1074 1075 1076=-=-=-=-= bsd.info.mk =-=-=-=-= 1077 1078The include file <bsd.info.mk> is used to generate and install GNU Info 1079documentation from respective Texinfo source files. It defines three 1080implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1081following variables: 1082 1083TEXINFO List of Texinfo source files. Info documentation will 1084 consist of single files with the extension replaced by 1085 .info. 1086 1087INFOFLAGS Flags to pass to makeinfo. [] 1088 1089 1090=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1091 1092The include file <bsd.kernobj.mk> defines variables related to the 1093location of kernel sources and object directories. 1094 1095KERNSRCDIR Is the location of the top of the kernel src. 1096 [${_SRC_TOP_}/sys] 1097 1098KERNARCHDIR Is the location of the machine dependent kernel sources. 1099 [arch/${MACHINE}] 1100 1101KERNCONFDIR Is where the configuration files for kernels are found. 1102 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1103 1104KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1105 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1106 The default value is 1107 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1108 if it exists or the target 'obj' is being made. 1109 Otherwise the default is 1110 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1111 1112It is important that Makefiles (such as those under src/distrib) that 1113wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1114rather than make assumptions about the location of the compiled kernel. 1115 1116 1117=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1118 1119The include file <bsd.kinc.mk> defines the many targets (includes, 1120subdirectories, etc.), and is used by kernel makefiles to handle 1121include file installation. It is intended to be included alone, by 1122kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1123Please see <bsd.kinc.mk> for more details, and keep the documentation 1124in that file up to date. 1125 1126=-=-=-=-= bsd.syscall.mk =-=-=-=-= 1127 1128The include file <bsd.syscall.mk> contains the logic to create syscall 1129files for various emulations. It includes <bsd.kinc.mk> to handle the 1130rest of the targets. 1131 1132=-=-=-=-= bsd.lib.mk =-=-=-=-= 1133 1134The include file <bsd.lib.mk> has support for building libraries. It has 1135the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1136includes, install, lint, and tags. Additionally, it has a checkver target 1137which checks for installed shared object libraries whose version is greater 1138that the version of the source. It has a limited number of suffixes, 1139consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1140<bsd.shlib.mk> to get shared library parameters. 1141 1142It sets/uses the following variables: 1143 1144LIB The name of the library to build. 1145 1146LIBDIR Target directory for libraries. 1147 1148MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1149 permissions in files inside its archives to those of 1150 the file it was fed. This leads to non-reproduceable 1151 builds. If MKARZERO is set to "yes" (default is the 1152 same as MKREPRO, or "no" if MKREPRO is not defined), 1153 then the "D" flag is passed to ar, causing the 1154 timestamp, uid and gid to be zeroed and the file 1155 permissions to be set to 644. This allows .a files 1156 from different builds to be bit identical. 1157 1158SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1159 is not "no". 1160 1161SHLIB_MAJOR 1162SHLIB_MINOR 1163SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1164 1165USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1166 as the path to install shared libraries to. 1167 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1168 Default: no 1169 1170LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1171 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no 1172 MKPROFILE=no MKSTATICLIB=no". 1173 Default: no 1174 1175LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no 1176 MKPROFILE=no", and don't install the (.a) library. 1177 This is useful for "build only" helper libraries. 1178 Default: no 1179 1180LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1181 shared libraries. 1182 This is useful for C++ libraries. 1183 Default: no 1184 1185LINTLIBDIR Target directory for lint libraries. 1186 1187LIBGRP Library group. 1188 1189LIBOWN Library owner. 1190 1191LIBMODE Library mode. 1192 1193LDADD Additional loader objects. 1194 1195MAN The manual pages to be installed (use a .1 - .9 suffix). 1196 1197NOCHECKVER_<library> 1198NOCHECKVER If set, disables checking for installed shared object 1199 libraries with versions greater than the source. A 1200 particular library name, without the "lib" prefix, may 1201 be appended to the variable name to disable the check for 1202 only that library. 1203 1204SRCS List of source files to build the library. Suffix types 1205 .s, .c, and .f are supported. Note, .s files are preferred 1206 to .c files of the same name. (This is not the default for 1207 versions of make.) 1208 1209LIBDPLIBS A list of the tuples: 1210 libname path-to-srcdir-of-libname 1211 1212 For each tuple; 1213 * LIBDO.libname contains the .OBJDIR of the library 1214 `libname', and if it is not set it is determined 1215 from the srcdir and added to MAKEOVERRIDES (the 1216 latter is to allow for build time optimization). 1217 * LDADD gets -L${LIBDO.libname} -llibname added. 1218 * DPADD gets ${LIBDO.libname}/liblibname.so or 1219 ${LIBDO.libname}/liblibname.a added. 1220 1221 The special value "_external" for LIBDO.lib makes the 1222 build system to assume the library comes from outside 1223 of the NetBSD source tree and only causes -llibname 1224 to be added to LDADD. 1225 1226 This variable may be used for individual libraries, as 1227 well as in parent directories to cache common libraries 1228 as a build-time optimization. 1229 1230The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1231if it exists, as well as the include file <bsd.man.mk>. 1232 1233It has rules for building profiled objects; profiled libraries are 1234built by default. 1235 1236Libraries are ranlib'd when made. 1237 1238 1239=-=-=-=-= bsd.links.mk =-=-=-=-= 1240 1241The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1242and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 1243 1244LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1245is used. The defaults may be modified by other bsd.*.mk files which 1246include bsd.links.mk. In the future, these variables may be replaced 1247by a method for explicitly recording hard links in a metadata log. 1248 1249LINKS The list of hard links, consisting of pairs of paths: 1250 source-file target-file 1251 ${DESTDIR} is prepended to both paths before linking. 1252 For example, to link /bin/test and /bin/[, use: 1253 LINKS=/bin/test /bin/[ 1254 1255CONFIGLINKS Similar semantics to LINKS, except that the links 1256 are installed by the `configinstall' target, 1257 not the `install' target. 1258 1259SYMLINKS The list of symbolic links, consisting of pairs of paths: 1260 source-file target-file 1261 ${DESTDIR} is only prepended to target-file before linking. 1262 For example, to symlink /usr/bin/tar to /bin/tar resulting 1263 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1264 SYMLINKS=/bin/tar /usr/bin/tar 1265 1266CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1267 are installed by the `configinstall' target, 1268 not the `install' target. 1269 1270LINKSOWN Link owner. [${BINOWN}] 1271 1272LINKSGRP Link group. [${BINGRP}] 1273 1274LINKSMODE Link mode. [${NONBINMODE}] 1275 1276LINKSOWN_<fn> Link owner of the specific file <fn>. 1277 1278LINKSGRP_<fn> Link group of the specific file <fn>. 1279 1280LINKSMODE_<fn> Link mode of the specific file <fn>. 1281 1282 1283=-=-=-=-= bsd.man.mk =-=-=-=-= 1284 1285The include file <bsd.man.mk> handles installing manual pages and their 1286links. 1287 1288It has a three targets: 1289 1290 catinstall: 1291 Install the preformatted manual pages and their links. 1292 htmlinstall: 1293 Install the HTML manual pages and their links. 1294 maninstall: 1295 Install the manual page sources and their links. 1296 1297It sets/uses the following variables: 1298 1299MANDIR Base path for manual installation. 1300 1301MANGRP Manual group. 1302 1303MANOWN Manual owner. 1304 1305MANMODE Manual mode. 1306 1307MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 1308 or "/tahoe" for machine specific manual pages. 1309 1310MAN The manual pages to be installed (use a .1 - .9 suffix). 1311 1312MLINKS List of manual page links (using a .1 - .9 suffix). The 1313 linked-to file must come first, the linked file second, 1314 and there may be multiple pairs. 1315 1316The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1317it exists. 1318 1319 1320=-=-=-=-= bsd.obj.mk =-=-=-=-= 1321 1322The include file <bsd.obj.mk> defines targets related to the creation 1323and use of separated object and source directories. 1324 1325If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1326${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1327it exists. Otherwise make(1) looks for the existence of a 1328subdirectory (or a symlink to a directory) of the source directory 1329into which built targets should be placed. If an environment variable 1330named MAKEOBJDIR is set, make(1) uses its value as the name of the 1331object directory; failing that, make first looks for a subdirectory 1332named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1333 1334Object directories are not created automatically by make(1) if they 1335don't exist; you need to run a separate "make obj". (This will happen 1336during a top-level build if "MKOBJDIRS" is set to a value other than 1337"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1338and this is determined by a simple string prefix comparison -- object 1339directories are created in a separate object directory tree, and a 1340symlink to the object directory in that tree is created in the source 1341directory; otherwise, "make obj" assumes that you're not in the main 1342source tree and that it's not safe to use a separate object tree. 1343 1344Several variables used by <bsd.obj.mk> control exactly what 1345directories and links get created during a "make obj": 1346 1347MAKEOBJDIR If set, this is the component name of the object 1348 directory. 1349 1350OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1351 object directories or links named "obj.${MACHINE}"; 1352 otherwise, just creates ones named "obj". 1353 1354USR_OBJMACHINE If set, and the current directory is a subdirectory of 1355 ${BSDSRCDIR}, create object directory in the 1356 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1357 otherwise, create it in the corresponding subdirectory 1358 of ${BSDOBJDIR} 1359 1360BUILDID If set, the contents of this variable are appended 1361 to the object directory name. If OBJMACHINE is also 1362 set, ".${BUILDID}" is added after ".${MACHINE}". 1363 1364 1365=-=-=-=-= bsd.prog.mk =-=-=-=-= 1366 1367The include file <bsd.prog.mk> handles building programs from one or 1368more source files, along with their manual pages. It has a limited number 1369of suffixes, consistent with the current needs of the BSD tree. 1370<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1371 1372It has eight targets: 1373 1374 all: 1375 build the program and its manual page. This also 1376 creates a GDB initialization file (.gdbinit) in 1377 the objdir. The .gdbinit file sets the shared library 1378 prefix to ${DESTDIR} to facilitate cross-debugging. 1379 clean: 1380 remove the program, any object files and the files a.out, 1381 Errs, errs, mklog, and ${PROG}.core. 1382 cleandir: 1383 remove all of the files removed by the target clean, as 1384 well as .depend, tags, and any manual pages. 1385 `distclean' is a synonym for `cleandir'. 1386 depend: 1387 make the dependencies for the source files, and store 1388 them in the file .depend. 1389 includes: 1390 install any header files. 1391 install: 1392 install the program and its manual pages; if the Makefile 1393 does not itself define the target install, the targets 1394 beforeinstall and afterinstall may also be used to cause 1395 actions immediately before and after the install target 1396 is executed. 1397 lint: 1398 run lint on the source files 1399 tags: 1400 create a tags file for the source files. 1401 1402It sets/uses the following variables: 1403 1404BINGRP Binary group. 1405 1406BINOWN Binary owner. 1407 1408BINMODE Binary mode. 1409 1410CLEANDIRFILES Additional files to remove for the cleandir target. 1411 1412CLEANFILES Additional files to remove for the clean and cleandir targets. 1413 1414COPTS Additional flags to the compiler when creating C objects. 1415 1416COPTS.<fn> Additional flags to the compiler when creating the 1417 C objects for <fn>. 1418 For <fn>.[ly], "<fn>.c" must be used. 1419 1420CPUFLAGS Additional flags to the compiler/assembler to select 1421 CPU instruction set options, CPU tuning options, etc. 1422 1423CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1424 For <fn>.[ly], "<fn>.c" must be used. 1425 1426CPPFLAGS Additional flags to the C pre-processor. 1427 1428CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1429 For <fn>.[ly], "<fn>.c" must be used. 1430 1431GDBINIT List of GDB initialization files to add to "source" 1432 directives in the .gdbinit file that is created in the 1433 objdir. 1434 1435LDADD Additional loader objects. Usually used for libraries. 1436 For example, to load with the compatibility and utility 1437 libraries, use: 1438 1439 LDADD+=-lutil -lcompat 1440 1441LDFLAGS Additional linker flags (passed to ${CC} during link). 1442 1443LINKS See <bsd.links.mk> 1444 1445OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1446 1447OBJCOPTS.<fn> Additional flags to the compiler when creating the 1448 ObjC objects for <fn>. 1449 For <fn>.[ly], "<fn>.c" must be used. 1450 1451SYMLINKS See <bsd.links.mk> 1452 1453MAN Manual pages (should end in .1 - .9). If no MAN variable is 1454 defined, "MAN=${PROG}.1" is assumed. 1455 1456PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1457 time, with the value of this variable as args to paxctl(1). 1458 1459PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1460 1461PROG The name of the program to build. If not supplied, nothing 1462 is built. 1463 1464PROG_CXX If defined, the name of the program to build. Also 1465 causes <bsd.prog.mk> to link the program with the C++ 1466 compiler rather than the C compiler. PROG_CXX overrides 1467 the value of PROG if PROG is also set. 1468 1469PROGNAME The name that the above program will be installed as, if 1470 different from ${PROG}. 1471 1472SRCS List of source files to build the program. If SRCS is not 1473 defined, it's assumed to be ${PROG}.c. 1474 1475DPSRCS List of source files which are needed for generating 1476 dependencies, but are not needed in ${SRCS}. 1477 1478DPADD Additional dependencies for the program. Usually used for 1479 libraries. For example, to depend on the compatibility and 1480 utility libraries use: 1481 1482 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1483 1484 The following system libraries are predefined for DPADD: 1485 1486
