1# $NetBSD: bsd.README,v 1.350 2016/02/07 14:31:21 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 139MKCOMPATTESTS If "yes", build and install the NetBSD test suite when 140 building and installing src/compat. 141 Default: no 142 143MKCOMPATX11 If "yes", build and install the X11 libraries when 144 building and installing src/compat. 145 Default: no 146 147MKCOMPLEX If "no", don't build libm support for <complex.h> 148 Default: yes 149 150MKCRYPTO If "no", no cryptography support will be built into the system, 151 and also acts as "MKKERBEROS=no". 152 Default: yes 153 154MKCRYPTO_RC5 If not "no", RC5 support will be built into libcrypto_rc5 155 Default: no 156 157MKCTF If "no", do not build and install CTF tools, and also 158 don't generate and manipulate CTF data of ELF binaries 159 during build. 160 Default: no 161 162NOCTF Don't generate and manipulate CTF data of ELF binaries 163 during build.

Useful 178 when stale dependencies are present, to list the exact 179 files that need refreshing. It is off by default because 180 it is possibly slower. 181 Default "no" 182 183MKDOC If "no", don't build or install the documentation. 184 Default: yes 185 186MKDTRACE If "no", do not build and install the kernel modules, 187 utilities and libraries used to implement the dtrace(1) 188 facility. 189 Default: no 190 191MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 192 don't install certain libraries in /lib, and don't 193 install the shared linker into /libexec. 194 Default: yes 195 196MKEXTSRC If not "no", 'make build' also descends into either src/extsrc 197 to cross-build programs and libraries externally added by 198 users, and automatically enables creation of those sets. 199 Default: no 200 201MKGCC If "no", don't build gcc(1) or any of the GCC-related 202 libraries (libgcc, libobjc, libstdc++). 203 Default: yes 204 205MKGCCCMDS If "no", don't build gcc(1), but do build the GCC-related 206 libraries (libgcc, libobjc, libstdc++). 207 Default: yes 208 209MKGDB If "no", don't build gdb(1). 210 Default: yes 211 212MKGROFFHTMLDOC If "no", avoid trying to use groff to generate html for 213 miscellaneous articles, as this seems to sometimes want 214 to run software not in base.

The 480 stack protection code imposes a performance penalty 481 of about 5%. 482 Default: "no", unless "USE_FORT" is set to "yes" 483 484USE_FORT If "yes" turns on substitute wrappers for commonly used 485 functions that do not do bounds checking regularly, but 486 they could in some cases by using the gcc 487 __builtin_object_size() function to determine the buffer 488 size where it is known and detect buffer overflows. 489 These substitute functions are in /usr/include/ssp. 490 Default: depends on the part of the source tree 491 492USE_YP If "no", disables building YP (NIS) support into 493 various system utilities/libraries that support it. 494 If ${MKYP} is "no", USE_YP will also be forced to "no". 495 496USE_PIGZGZIP If "no", use the host "gzip" program to compress things. 497 Otherwise, build tools/pigz, set TOOL_GZIP=${TOOL_PIGZ}, 498 and use nbpigz to compress things. 499 Default: "no". 500 501COPTS.lib<lib> 502OBJCOPTS.lib<lib> 503LDADD.lib<lib> 504CPPFLAGS.lib<lib> 505CXXFLAGS.lib<lib> 506COPTS.<prog> 507OBJCCOPTS.<prog> 508LDADD.<prog> 509CPPFLAGS.<prog> 510CXXFLAGS.<prog> These provide a way to specify additions to the associated 511 variables in a way that applies only to a particular library 512 or program. <lib> corresponds to the LIB variable set in 513 the library's makefile. <prog> corresponds to either PROG 514 or PROG_CXX (if set). For example, if COPTS.libcrypto is 515 set to "-g", "-g" will be added to COPTS only when compiling 516 the crypto library. 517 518The active compiler is selected using the following variables: 519AVAILABLE_COMPILER 520 List of available compiler suites. Processed in order 521 for selecting the active compiler for each frontend. 522HAVE_PCC If defined, PCC is present and enabled. 523HAVE_LLVM If defined, LLVM/Clang is present and enabled. 524UNSUPPORTED_COMPILER.xxx 525 If defined, the support for compiler "xxx" is disabled. 526 527For the frontends (CC, CPP, CXX, FC and OBJC) the following variables exist: 528ACTIVE_CC Active compile suite for the CC frontend. 529SUPPORTED_CC Compile suite with support for the CC frontend. 530TOOL_CC.xxx Path to the CC frontend for compiler "xxx" 531 532=-=-=-=-= sys.mk =-=-=-=-= 533 534The include file <sys.mk> has the default rules for all makes, in the BSD 535environment or otherwise. You probably don't want to touch this file. 536 537=-=-=-=-= bsd.own.mk =-=-=-=-= 538 539The include file <bsd.own.mk> contains source tree configuration parameters, 540such as the owners, groups, etc. for both manual pages and binaries, and 541a few global "feature configuration" parameters. 542 543It has no targets. 544 545To get system-specific configuration parameters, <bsd.own.mk> will try to 546include the file specified by the "MAKECONF" variable. If MAKECONF is not 547set, or no such file exists, the system make configuration file, /etc/mk.conf 548is included. These files may define any of the variables described below. 549 550<bsd.own.mk> sets the following variables, if they are not already defined 551(defaults are in brackets): 552 553NETBSDSRCDIR Top of the NetBSD source tree. 554 If _SRC_TOP_ != "", that will be used as the default, 555 otherwise BSDSRCDIR will be used as the default. 556 Various makefiles within the NetBSD source tree will 557 use this to reference the top level of the source tree. 558 559_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 560 based on the presence of tools/ and build.sh. This variable 561 is "internal" to <bsd.own.mk>, although its value is only 562 determined once and then propagated to all sub-makes. 563 564_NETBSD_VERSION_DEPENDS 565 A list of files which contain information about 566 the version of the NetBSD being built. This is 567 defined only if the current directory appears 568 to be inside a NetBSD source tree. The list of 569 files includes ${NETBSDSRCDIR}/sys/sys/param.h 570 (which contains the kernel version number), 571 ${NETBSDSRCDIR}/sys/conf/newvers.sh and 572 ${NETBSDSRCDIR}/sys/conf/osrelease.sh (which 573 interpret the information in sys/sys/param.h), and 574 ${_SRC_TOP_OBJ_}/params (which is an optional file, 575 created by "make build" in ${_SRC_TOP_}/Makefile, 576 containing all the variables that may influence the 577 build). 578 579 Targets that depend on the NetBSD version, or on 580 variables defined at build time, can declare a 581 dependency on ${_NETBSD_VERSION_DEPENDS}, like this: 582 583 version.c: ${_NETBSD_VERSION_DEPENDS} 584 commands to create version.c 585 586BSDSRCDIR The real path to the system sources, so that 'make obj' 587 will work correctly.

[${MACHINE}] 702 703Additionally, the following variables may be set by <bsd.own.mk> or in a 704make configuration file to modify the behavior of the system build 705process (default values are in brackets along with comments, if set by 706<bsd.own.mk>): 707 708USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 709 be used as part of a build in progress. 710 Supported values: 711 712 yes Use the tools from TOOLDIR. 713 Must be set to this if cross-compiling. 714 715 no Do not use the tools from TOOLDIR, but refuse to 716 build native compilation tool components that are 717 version-specific for that tool. 718 719 never Do not use the tools from TOOLDIR, even when 720 building native tool components. This is similar to 721 the traditional NetBSD build method, but does not 722 verify that the compilation tools in use are 723 up-to-date enough in order to build the tree 724 successfully. This may cause build or runtime 725 problems when building the whole NetBSD source tree. 726 727 Default: "yes" if building all or part of a whole NetBSD 728 source tree (detected automatically); "no" otherwise 729 (to preserve traditional semantics of the <bsd.*.mk> 730 make(1) include files). 731 732OBJECT_FMT Object file format. [set to "ELF" on architectures that 733 use ELF -- currently all architectures]. 734 735TOOLCHAIN_MISSING 736 If not "no", this indicates that the platform being built 737 does not have a working in-tree toolchain. If the 738 ${MACHINE_ARCH} in question falls into this category, 739 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 740 Otherwise, the variable is unconditionally assigned the 741 value "no". 742 If not "no", ${MKBINUTILS}, ${MKGCC}, and ${MKGDB} are 743 unconditionally assigned the value "no". 744 745EXTERNAL_TOOLCHAIN 746 This variable is not directly set by <bsd.own.mk>, but 747 including <bsd.own.mk> is the canonical way to gain 748 access to this variable. The variable should be defined 749 either in the user's environment or in the user's mk.conf 750 file. If defined, this variable indicates the root of 751 an external toolchain which will be used to build the 752 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 753 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 754 cross-compile framework. 755 756 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 757 assigned the value "no", since the external version of the 758 compiler may not be able to build the library components of 759 the in-tree compiler. 760 761 NOTE: This variable is not yet used in as many places as 762 it should be. Expect the exact semantics of this variable 763 to change in the short term as parts of the cross-compile 764 framework continue to be cleaned up. 765 766The following variables are defined to commands to perform the 767appropriate operation, with the default in [brackets].

This keeps those definitions in 919centralized place. 920 921<bsd.own.mk> is generally useful when building your own Makefiles so that 922they use the same default owners etc. as the rest of the tree. 923 924 925=-=-=-=-= bsd.clean.mk =-=-=-=-= 926 927The include file <bsd.clean.mk> defines the clean and cleandir 928targets. It uses the following variables: 929 930CLEANFILES Files to remove for both the clean and cleandir targets. 931 932CLEANDIRFILES Files to remove for the cleandir target, but not for 933 the clean target. 934 935MKCLEANSRC Controls whether or not the clean and cleandir targets 936 will delete files from both the object directory, 937 ${.OBJDIR}, and the source directory, ${.CURDIR}. 938 939 If MKCLEANSRC is set to "no", then the file names in 940 CLEANFILES or CLEANDIRFILES are interpreted relative 941 to the object directory, ${.OBJDIR}. This is the 942 traditional behaviour. 943 944 If MKCLEANSRC is set to "yes", then the file deletion 945 is performed relative to both the object directory, 946 ${.OBJDIR}, and the source directory, ${.CURDIR}. (This 947 has no effect if ${.OBJDIR} is the same as ${.CURDIR}.) 948 Deleting files from ${.CURDIR} is intended to remove 949 stray output files that had been left in the source 950 directory by an earlier build that did not use object 951 directories. 952 953 The default is MKCLEANSRC=yes. If you always build with 954 separate object directories, and you are sure that there 955 are no stray files in the source directories, then you 956 may set MKCLEANSRC=no to save some time. 957 958MKCLEANVERIFY Controls whether or not the clean and cleandir targets 959 will verify that files have been deleted. 960 961 If MKCLEANVERIFY is set to "no", then the files will 962 be deleted using a "rm -f" command, and its success or 963 failure will be ignored. 964 965 If MKCLEANVERIFY is set to "yes", then the success of 966 the "rm -f" command will be verified using an "ls" 967 command. 968 969 The default is MKCLEANVERIFY=yes. If you are sure that 970 there will be no problems caused by file permissions, 971 read-only file systems, or the like, then you may set 972 MKCLEANVERIFY=no to save some time. 973 974To use the clean and cleandir targets defined in <bsd.clean.mk>, other 975Makefiles or bsd.*.mk files should append file names to the CLEANFILES 976or CLEANDIRFILES variables. For example: 977 978 CLEANFILES+= a.out 979 CLEANDIRFILES+= .depend 980 981 .include <bsd.clean.mk> 982 983The files listed in CLEANFILES and CLEANDIRFILES must not be 984directories, because the potential risk from running "rm -rf" commands 985in bsd.clean.mk is considered too great. If you want to recursively 986delete a directory as part of "make clean" or "make cleandir" then you 987need to provide your own target. 988 989=-=-=-=-= bsd.dep.mk =-=-=-=-= 990 991The include file <bsd.dep.mk> contains the default targets for building 992.depend files. It creates .d files from entries in SRCS and DPSRCS 993that are C, C++, or Objective C source files, and builds .depend from the 994.d files. All other files in SRCS and all of DPSRCS will be used as 995dependencies for the .d files. In order for this to function correctly, 996it should be .included after all other .mk files and directives that may 997modify SRCS or DPSRCS. It uses the following variables: 998 999SRCS List of source files to build the program. 1000 1001DPSRCS List of source files which are needed for generating 1002 dependencies, but are not needed in ${SRCS}. 1003 1004 1005=-=-=-=-= bsd.files.mk =-=-=-=-= 1006 1007The include file <bsd.files.mk> handles the FILES variables and is included 1008from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 1009 1010FILES The list of files to install. 1011 1012CONFIGFILES Similar semantics to FILES, except that the files 1013 are installed by the `configinstall' target, 1014 not the `install' target. 1015 The FILES* variables documented below also apply. 1016 1017FILESOWN File owner. [${BINOWN}] 1018 1019FILESGRP File group. [${BINGRP}] 1020 1021FILESMODE File mode. [${NONBINMODE}] 1022 1023FILESDIR The location to install the files. 1024 1025FILESNAME Optional name to install each file as. 1026 1027FILESOWN_<fn> File owner of the specific file <fn>. 1028 1029FILESGRP_<fn> File group of the specific file <fn>. 1030 1031FILESMODE_<fn> File mode of the specific file <fn>. 1032 1033FILESDIR_<fn> The location to install the specific file <fn>. 1034 1035FILESNAME_<fn> Optional name to install <fn> as. 1036 1037FILESBUILD If this variable is defined, then its value will be 1038 used as the default for all FILESBUILD_<fn> variables. 1039 Otherwise, the default will be "no". 1040 1041FILESBUILD_<fn> A value different from "no" will add the file to the list of 1042 targets to be built by `realall'. Users of that variable 1043 should provide a target to build the file. 1044 1045 1046BUILDSYMLINKS List of two word items: 1047 lnsrc lntgt 1048 For each lnsrc item, create a symlink named lntgt. 1049 The lntgt symlinks are removed by the cleandir target. 1050 1051UUDECODE_FILES List of files which are stored as <file>.uue in the source 1052 tree. Each one will be decoded with ${TOOL_UUDECODE}. 1053 The source files have a `.uue' suffix, the generated files do 1054 not. 1055 1056UUDECODE_FILES_RENAME_<fn> 1057 Rename the output from the decode to the provided name. 1058 1059 *NOTE: These files are simply decoded, with no install or other 1060 rule applying implicitly except being added to the clean 1061 target. 1062 1063=-=-=-=-= bsd.gcc.mk =-=-=-=-= 1064 1065The include file <bsd.gcc.mk> computes various parameters related to GCC 1066support libraries. It defines no targets. <bsd.own.mk> MUST be included 1067before <bsd.gcc.mk>. 1068 1069The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 1070of which need to know where to find certain GCC support libraries. 1071 1072The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 1073which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 1074the compiler is asked where to find the support libraries, otherwise the 1075support libraries are found in ${DESTDIR}/usr/lib. 1076 1077<bsd.gcc.mk> sets the following variables: 1078 1079_GCC_CRTBEGIN The full path name to crtbegin.o. 1080 1081_GCC_CRTBEGINS The full path name to crtbeginS.o. 1082 1083_GCC_CRTEND The full path name to crtend.o. 1084 1085_GCC_CRTENDS The full path name to crtendS.o. 1086 1087_GCC_LIBGCCDIR The directory where libgcc.a is located. 1088 1089 1090=-=-=-=-= bsd.inc.mk =-=-=-=-= 1091 1092The include file <bsd.inc.mk> defines the includes target and uses the 1093variables: 1094 1095INCS The list of include files. 1096 1097INCSDIR The location to install the include files. 1098 1099INCSNAME Target name of the include file, if only one; same as 1100 FILESNAME, but for include files. 1101 1102INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 1103 are installed in the 'includes' target and not the 1104 (much later) 'install' target. 1105 1106INCSNAME_<file> The name file <file> should be installed as, if not <file>, 1107 same as FILESNAME_<file>, but for include files. 1108 1109 1110=-=-=-=-= bsd.info.mk =-=-=-=-= 1111 1112The include file <bsd.info.mk> is used to generate and install GNU Info 1113documentation from respective Texinfo source files. It defines three 1114implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 1115following variables: 1116 1117TEXINFO List of Texinfo source files. Info documentation will 1118 consist of single files with the extension replaced by 1119 .info. 1120 1121INFOFLAGS Flags to pass to makeinfo. [] 1122 1123 1124=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 1125 1126The include file <bsd.kernobj.mk> defines variables related to the 1127location of kernel sources and object directories. 1128 1129KERNSRCDIR Is the location of the top of the kernel src. 1130 [${_SRC_TOP_}/sys] 1131 1132KERNARCHDIR Is the location of the machine dependent kernel sources. 1133 [arch/${MACHINE}] 1134 1135KERNCONFDIR Is where the configuration files for kernels are found. 1136 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 1137 1138KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 1139 instance will be compiled in ${KERNOBJDIR}/GENERIC. 1140 The default value is 1141 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 1142 if it exists or the target 'obj' is being made. 1143 Otherwise the default is 1144 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 1145 1146It is important that Makefiles (such as those under src/distrib) that 1147wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 1148rather than make assumptions about the location of the compiled kernel. 1149 1150 1151=-=-=-=-= bsd.kinc.mk =-=-=-=-= 1152 1153The include file <bsd.kinc.mk> defines the many targets (includes, 1154subdirectories, etc.), and is used by kernel makefiles to handle 1155include file installation. It is intended to be included alone, by 1156kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 1157Please see <bsd.kinc.mk> for more details, and keep the documentation 1158in that file up to date. 1159 1160=-=-=-=-= bsd.syscall.mk =-=-=-=-= 1161 1162The include file <bsd.syscall.mk> contains the logic to create syscall 1163files for various emulations. It includes <bsd.kinc.mk> to handle the 1164rest of the targets. 1165 1166=-=-=-=-= bsd.lib.mk =-=-=-=-= 1167 1168The include file <bsd.lib.mk> has support for building libraries. It has 1169the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 1170includes, install, lint, and tags. Additionally, it has a checkver target 1171which checks for installed shared object libraries whose version is greater 1172that the version of the source. It has a limited number of suffixes, 1173consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 1174<bsd.shlib.mk> to get shared library parameters. 1175 1176It sets/uses the following variables: 1177 1178LIB The name of the library to build. 1179 1180LIBDIR Target directory for libraries. 1181 1182MKARZERO Normally, ar(1) sets the timestamps, uid, gid and 1183 permissions in files inside its archives to those of 1184 the file it was fed. This leads to non-reproduceable 1185 builds. If MKARZERO is set to "yes" (default is the 1186 same as MKREPRO, or "no" if MKREPRO is not defined), 1187 then the "D" flag is passed to ar, causing the 1188 timestamp, uid and gid to be zeroed and the file 1189 permissions to be set to 644. This allows .a files 1190 from different builds to be bit identical. 1191 1192SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 1193 is not "no". 1194 1195SHLIB_MAJOR 1196SHLIB_MINOR 1197SHLIB_TEENY Major, minor, and teeny version numbers of shared library 1198 1199USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 1200 as the path to install shared libraries to. 1201 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 1202 Default: no 1203 1204LIBISMODULE If not "no", install as ${LIB}.so (without the "lib" prefix), 1205 and act as "MKDEBUGLIB=no MKLINT=no MKPICINSTALL=no 1206 MKPROFILE=no MKSTATICLIB=no". 1207 Default: no 1208 1209LIBISPRIVATE If not "no", act as "MKDEBUGLIB=no MKLINT=no MKPIC=no 1210 MKPROFILE=no", and don't install the (.a) library. 1211 This is useful for "build only" helper libraries. 1212 Default: no 1213 1214LIBISCXX If not "no", Use ${CXX} instead of ${CC} to link 1215 shared libraries. 1216 This is useful for C++ libraries. 1217 Default: no 1218 1219LINTLIBDIR Target directory for lint libraries. 1220 1221LIBGRP Library group. 1222 1223LIBOWN Library owner. 1224 1225LIBMODE Library mode. 1226 1227LDADD Additional loader objects. 1228 1229MAN The manual pages to be installed (use a .1 - .9 suffix). 1230 1231NOCHECKVER_<library> 1232NOCHECKVER If set, disables checking for installed shared object 1233 libraries with versions greater than the source. A 1234 particular library name, without the "lib" prefix, may 1235 be appended to the variable name to disable the check for 1236 only that library. 1237 1238SRCS List of source files to build the library. Suffix types 1239 .s, .c, and .f are supported. Note, .s files are preferred 1240 to .c files of the same name. (This is not the default for 1241 versions of make.) 1242 1243LIBDPLIBS A list of the tuples: 1244 libname path-to-srcdir-of-libname 1245 1246 For each tuple; 1247 * LIBDO.libname contains the .OBJDIR of the library 1248 `libname', and if it is not set it is determined 1249 from the srcdir and added to MAKEOVERRIDES (the 1250 latter is to allow for build time optimization). 1251 * LDADD gets -L${LIBDO.libname} -llibname added. 1252 * DPADD gets ${LIBDO.libname}/liblibname.so or 1253 ${LIBDO.libname}/liblibname.a added. 1254 1255 The special value "_external" for LIBDO.lib makes the 1256 build system to assume the library comes from outside 1257 of the NetBSD source tree and only causes -llibname 1258 to be added to LDADD. 1259 1260 This variable may be used for individual libraries, as 1261 well as in parent directories to cache common libraries 1262 as a build-time optimization. 1263 1264The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 1265if it exists, as well as the include file <bsd.man.mk>. 1266 1267It has rules for building profiled objects; profiled libraries are 1268built by default. 1269 1270Libraries are ranlib'd when made. 1271 1272 1273=-=-=-=-= bsd.links.mk =-=-=-=-= 1274 1275The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 1276and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 1277 1278LINKSOWN, LINKSGRP, and LINKSMODE, are relevant only if a metadata log 1279is used. The defaults may be modified by other bsd.*.mk files which 1280include bsd.links.mk. In the future, these variables may be replaced 1281by a method for explicitly recording hard links in a metadata log. 1282 1283LINKS The list of hard links, consisting of pairs of paths: 1284 source-file target-file 1285 ${DESTDIR} is prepended to both paths before linking. 1286 For example, to link /bin/test and /bin/[, use: 1287 LINKS=/bin/test /bin/[ 1288 1289CONFIGLINKS Similar semantics to LINKS, except that the links 1290 are installed by the `configinstall' target, 1291 not the `install' target. 1292 1293SYMLINKS The list of symbolic links, consisting of pairs of paths: 1294 source-file target-file 1295 ${DESTDIR} is only prepended to target-file before linking. 1296 For example, to symlink /usr/bin/tar to /bin/tar resulting 1297 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 1298 SYMLINKS=/bin/tar /usr/bin/tar 1299 1300CONFIGSYMLINKS Similar semantics to SYMLINKS, except that the symbolic links 1301 are installed by the `configinstall' target, 1302 not the `install' target. 1303 1304LINKSOWN Link owner. [${BINOWN}] 1305 1306LINKSGRP Link group. [${BINGRP}] 1307 1308LINKSMODE Link mode. [${NONBINMODE}] 1309 1310LINKSOWN_<fn> Link owner of the specific file <fn>. 1311 1312LINKSGRP_<fn> Link group of the specific file <fn>. 1313 1314LINKSMODE_<fn> Link mode of the specific file <fn>. 1315 1316 1317=-=-=-=-= bsd.man.mk =-=-=-=-= 1318 1319The include file <bsd.man.mk> handles installing manual pages and their 1320links. 1321 1322It has a three targets: 1323 1324 catinstall: 1325 Install the preformatted manual pages and their links. 1326 htmlinstall: 1327 Install the HTML manual pages and their links. 1328 maninstall: 1329 Install the manual page sources and their links. 1330 1331It sets/uses the following variables: 1332 1333MANDIR Base path for manual installation. 1334 1335MANGRP Manual group. 1336 1337MANOWN Manual owner. 1338 1339MANMODE Manual mode. 1340 1341MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 1342 or "/tahoe" for machine specific manual pages. 1343 1344MAN The manual pages to be installed (use a .1 - .9 suffix). 1345 1346MLINKS List of manual page links (using a .1 - .9 suffix). The 1347 linked-to file must come first, the linked file second, 1348 and there may be multiple pairs. 1349 1350The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 1351it exists. 1352 1353 1354=-=-=-=-= bsd.obj.mk =-=-=-=-= 1355 1356The include file <bsd.obj.mk> defines targets related to the creation 1357and use of separated object and source directories. 1358 1359If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 1360${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 1361it exists. Otherwise make(1) looks for the existence of a 1362subdirectory (or a symlink to a directory) of the source directory 1363into which built targets should be placed. If an environment variable 1364named MAKEOBJDIR is set, make(1) uses its value as the name of the 1365object directory; failing that, make first looks for a subdirectory 1366named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 1367 1368Object directories are not created automatically by make(1) if they 1369don't exist; you need to run a separate "make obj". (This will happen 1370during a top-level build if "MKOBJDIRS" is set to a value other than 1371"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 1372and this is determined by a simple string prefix comparison -- object 1373directories are created in a separate object directory tree, and a 1374symlink to the object directory in that tree is created in the source 1375directory; otherwise, "make obj" assumes that you're not in the main 1376source tree and that it's not safe to use a separate object tree. 1377 1378Several variables used by <bsd.obj.mk> control exactly what 1379directories and links get created during a "make obj": 1380 1381MAKEOBJDIR If set, this is the component name of the object 1382 directory. 1383 1384OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 1385 object directories or links named "obj.${MACHINE}"; 1386 otherwise, just creates ones named "obj". 1387 1388USR_OBJMACHINE If set, and the current directory is a subdirectory of 1389 ${BSDSRCDIR}, create object directory in the 1390 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 1391 otherwise, create it in the corresponding subdirectory 1392 of ${BSDOBJDIR} 1393 1394BUILDID If set, the contents of this variable are appended 1395 to the object directory name. If OBJMACHINE is also 1396 set, ".${BUILDID}" is added after ".${MACHINE}". 1397 1398 1399=-=-=-=-= bsd.prog.mk =-=-=-=-= 1400 1401The include file <bsd.prog.mk> handles building programs from one or 1402more source files, along with their manual pages. It has a limited number 1403of suffixes, consistent with the current needs of the BSD tree. 1404<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 1405 1406It has eight targets: 1407 1408 all: 1409 build the program and its manual page. This also 1410 creates a GDB initialization file (.gdbinit) in 1411 the objdir. The .gdbinit file sets the shared library 1412 prefix to ${DESTDIR} to facilitate cross-debugging. 1413 clean: 1414 remove the program, any object files and the files a.out, 1415 Errs, errs, mklog, and ${PROG}.core. 1416 cleandir: 1417 remove all of the files removed by the target clean, as 1418 well as .depend, tags, and any manual pages. 1419 `distclean' is a synonym for `cleandir'. 1420 depend: 1421 make the dependencies for the source files, and store 1422 them in the file .depend. 1423 includes: 1424 install any header files. 1425 install: 1426 install the program and its manual pages; if the Makefile 1427 does not itself define the target install, the targets 1428 beforeinstall and afterinstall may also be used to cause 1429 actions immediately before and after the install target 1430 is executed. 1431 lint: 1432 run lint on the source files 1433 tags: 1434 create a tags file for the source files. 1435 1436It sets/uses the following variables: 1437 1438BINGRP Binary group. 1439 1440BINOWN Binary owner. 1441 1442BINMODE Binary mode. 1443 1444CLEANDIRFILES Additional files to remove for the cleandir target. 1445 1446CLEANFILES Additional files to remove for the clean and cleandir targets. 1447 1448CONFIGOPTS Additional flags to config(1) when building kernels. 1449 1450COPTS Additional flags to the compiler when creating C objects. 1451 1452COPTS.<fn> Additional flags to the compiler when creating the 1453 C objects for <fn>. 1454 For <fn>.[ly], "<fn>.c" must be used. 1455 1456CPUFLAGS Additional flags to the compiler/assembler to select 1457 CPU instruction set options, CPU tuning options, etc. 1458 1459CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 1460 For <fn>.[ly], "<fn>.c" must be used. 1461 1462CPPFLAGS Additional flags to the C pre-processor. 1463 1464CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 1465 For <fn>.[ly], "<fn>.c" must be used. 1466 1467GDBINIT List of GDB initialization files to add to "source" 1468 directives in the .gdbinit file that is created in the 1469 objdir. 1470 1471LDADD Additional loader objects. Usually used for libraries. 1472 For example, to load with the compatibility and utility 1473 libraries, use: 1474 1475 LDADD+=-lutil -lcompat 1476 1477LDFLAGS Additional linker flags (passed to ${CC} during link). 1478 1479LINKS See <bsd.links.mk> 1480 1481OBJCOPTS Additional flags to the compiler when creating ObjC objects. 1482 1483OBJCOPTS.<fn> Additional flags to the compiler when creating the 1484 ObjC objects for <fn>. 1485 For <fn>.[ly], "<fn>.c" must be used. 1486 1487SYMLINKS See <bsd.links.mk> 1488 1489MAN Manual pages (should end in .1 - .9). If no MAN variable is 1490 defined, "MAN=${PROG}.1" is assumed. 1491 1492PAXCTL_FLAGS If defined, run paxctl(1) on the program binary after link 1493 time, with the value of this variable as args to paxctl(1). 1494 1495PAXCTL_FLAGS.${PROG} Custom override for PAXCTL_FLAGS. 1496 1497PROG The name of the program to build. If not supplied, nothing 1498 is built. 1499 1500PROG_CXX If defined, the name of the program to build. Also 1501 causes <bsd.prog.mk> to link the program with the C++ 1502 compiler rather than the C compiler. PROG_CXX overrides 1503 the value of PROG if PROG is also set. 1504 1505PROGNAME The name that the above program will be installed as, if 1506 different from ${PROG}. 1507 1508SRCS List of source files to build the program. If SRCS is not 1509 defined, it's assumed to be ${PROG}.c. 1510 1511DPSRCS List of source files which are needed for generating 1512 dependencies, but are not needed in ${SRCS}. 1513 1514DPADD Additional dependencies for the program. Usually used for 1515 libraries. For example, to depend on the compatibility and 1516 utility libraries use: 1517 1518 DPADD+=${LIBCOMPAT} ${LIBUTIL} 1519 1520 The following system libraries are predefined for DPADD: 1521 1522
