1# $NetBSD: bsd.README,v 1.145 2004/02/06 22:13:58 jwise Exp $ 2# @(#)bsd.README 8.2 (Berkeley) 4/2/94 3 4This is the README file for the new make "include" files for the BSD 5source tree. The files are installed in /usr/share/mk, and are, by 6convention, 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 ".so" 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 69MKxxx Can be set to "no" to disable functionality, or 70 "yes" to enable it. 71 Usually defaults to "yes", although some variables 72 default to "no". 73 Due to make(1) implementation issues, if a temporary 74 command-line override of a mk.conf or <bsd.own.mk> 75 setting is required whilst still honouring a particular 76 Makefile's setting of MKxxx, use 77 env MKxxx=value make 78 instead of 79 make MKxxx=value 80 81NOxxx If defined, disables a feature. 82 Not intended for users. 83 This is to allow Makefiles to disable functionality 84 that they don't support (such as missing man pages). 85 NOxxx variables must be defined before <bsd.own.mk> 86 is included. 87 88The following variables that control how things are made/installed that 89are not set by default. These should not be set by Makefiles; they're for 90the user to define in MAKECONF (see <bsd.own.mk>, below) or on the make(1) 91command line: 92 93BUILD If defined, 'make install' checks that the targets in the 94 source directories are up-to-date and remakes them if they 95 are out of date, instead of blindly trying to install 96 out of date or non-existent targets. 97 98MAKEVERBOSE Control how "verbose" the standard make(1) rules are. 99 Default: 2 100 Supported values: 101 0 Minimal output ("quiet") 102 1 Describe what is occurring 103 2 Describe what is occurring and echo the actual command 104 105 106MKBFD If "no", don't build libbfd, libiberty, or any of the things 107 that depend on them (binutils/gas/ld, gdb, dbsym, mdsetimage). 108 Default: yes 109 110MKCATPAGES If "no", don't build or install the catman pages. 111 Default: yes 112 113MKCRYPTO If "no", no cryptography support will be built into the system, 114 and also acts as "MKKERBEROS=no MKKERBEROS4=no". 115 Default: yes 116 117MKCRYPTO_IDEA If not "no", IDEA support will be built into libcrypto_idea.a. 118 Default: no 119 120MKCRYPTO_MDC2 If not "no", MDC2 support will be built into libcrypto_mdc2.a 121 Default: no 122 123MKCRYPTO_RC5 If not "no", RC5 support will be built into libcrypto_rc5.a. 124 Default: no 125 126MKCVS If "no", don't build or install cvs(1). 127 Default: yes 128 129MKDOC If "no", don't build or install the documentation. 130 Default: yes 131 132MKDYNAMICROOT If "no", build programs in /bin and /sbin statically, 133 don't install certain libraries in /lib, and don't 134 install the shared linker into /libexec. 135 Default: yes 136 137MKGCC If "no", don't build gcc(1) or any of the gcc-related 138 libraries (libg2c, libgcc, libobjc, libstdc++). 139 Default: yes 140 141MKGCCCMDS If "no", don't build gcc(1). 142 Default: yes 143 144MKGDB If "no", don't build gdb(1). 145 Default: yes 146 147MKHESIOD If "no", disables building of Hesiod infrastructure 148 (libraries and support programs). 149 Default: yes 150 151MKHOSTOBJ If not "no", for programs intended to be run on the compile 152 host, the name, release, and architecture of the host 153 operating system will be suffixed to the name of the object 154 directory created by "make obj". 155 Default: no 156 157MKHTML If "no", don't build or install the html man pages. 158 Default: yes 159 160MKIEEEFP If "no", don't add code for IEEE754/IEC60559 conformance. 161 Has no effect on most platforms. 162 Default: yes 163 164MKINFO If "no", don't build or install Info documentation from 165 Texinfo source files. 166 Default: yes 167 168MKKERBEROS4 If "no", disables building of Kerberos v4 169 infrastructure (libraries and support programs). 170 Default: yes 171 172MKKERBEROS If "no", disables building of Kerberos v5 173 infrastructure (libraries and support programs). 174 Default: yes 175 176MKLINKLIB If "no", act as "MKPICINSTALL=no MKPROFILE=no". 177 Also: 178 -

This allows a 251 non-root "make install". 252 Default: no 253 254MKUPDATE If not "no", 'make install' only installs targets that are 255 more recently modified in the source directories that their 256 installed counterparts. 257 Default: no 258 259MKUUCP If "no", don't build or install uucp(1). 260 Default: yes 261 262MKX11 If not "no", 'make build' also descends into src/x11 263 to cross build X11R6 and automatically enables creation 264 of X sets. 265 Default: no 266 267MKYP If "no", disables building of YP (NIS) 268 infrastructure (libraries and support programs). 269 Default: yes 270 271USE_HESIOD If "no", disables building Hesiod support into 272 various system utilities/libraries that support it. 273 If ${MKHESIOD} is "no", USE_HESIOD will also be 274 forced to "no". 275 276USE_KERBEROS4 If "no", disables building Kerberos v4 277 support into various system utilities/libraries that 278 support it. If ${MKKERBEROS4} is "no", USE_KERBEROS4 279 will also be forced to "no". 280 281USE_KERBEROS If "no", disables building Kerberos v4 or v5) 282 support into various system utilities/libraries that 283 support it. If ${MKKERBEROS} is "no", USE_KERBEROS 284 will also be forced to "no". 285 286USE_SKEY If "no", disables building S/key authentication 287 support into various system utilities/libraries that 288 support it. If ${MKSKEY} is "no", USE_SKEY will 289 also be forced to "no". 290 291USE_YP If "no", disables building YP (NIS) support into 292 various system utilities/libraries that support it. 293 If ${MKYP} is "no", USE_YP will also be forced to "no". 294 295COPTS.lib<lib> 296LDADD.lib<lib> 297CPPFLAGS.lib<lib> 298CXXFLAGS.lib<lib> 299COPTS.<prog> 300LDADD.<prog> 301CPPFLAGS.<prog> 302CXXFLAGS.<prog> These provide a way to specify additions to the associated 303 variables in a way that applies only to a particular library 304 or program. <lib> corresponds to the LIB variable set in 305 the library's makefile. <prog> corresponds to either PROG 306 or PROG_CXX (if set). For example, if COPTS.libcrypto is 307 set to "-g", "-g" will be added to COPTS only when compiling 308 the crypto library. 309 310=-=-=-=-= sys.mk =-=-=-=-= 311 312The include file <sys.mk> has the default rules for all makes, in the BSD 313environment or otherwise. You probably don't want to touch this file. 314 315=-=-=-=-= bsd.own.mk =-=-=-=-= 316 317The include file <bsd.own.mk> contains source tree configuration parameters, 318such as the owners, groups, etc. for both manual pages and binaries, and 319a few global "feature configuration" parameters. 320 321It has no targets. 322 323To get system-specific configuration parameters, <bsd.own.mk> will try to 324include the file specified by the "MAKECONF" variable. If MAKECONF is not 325set, or no such file exists, the system make configuration file, /etc/mk.conf 326is included. These files may define any of the variables described below. 327 328<bsd.own.mk> sets the following variables, if they are not already defined 329(defaults are in brackets): 330 331NETBSDSRCDIR Top of the NetBSD source tree. 332 If _SRC_TOP_ != "", that will be used as the default, 333 otherwise BSDSRCDIR will be used as the default. 334 Various makefiles within the NetBSD source tree will 335 use this to reference the top level of the source tree. 336 337_SRC_TOP_ Top of the system source tree, as determined by <bsd.own.mk> 338 based on the presence of tools/ and build.sh. This variable 339 is "internal" to <bsd.own.mk>, although its value is only 340 determined once and then propagated to all sub-makes. 341 342BSDSRCDIR The real path to the system sources, so that 'make obj' 343 will work correctly. [/usr/src] 344 345BSDOBJDIR The real path to the system 'obj' tree, so that 'make obj' 346 will work correctly. [/usr/obj] 347 348BINGRP Binary group. [wheel] 349 350BINOWN Binary owner.

[wheel] 396 397NLSOWN Native Language Support files owner. [root] 398 399NLSMODE Native Language Support files mode. [${NONBINMODE}] 400 401X11SRCDIR The path to the xsrc tree. [/usr/xsrc] 402 403X11SRCDIR.xc The path to the X11R6 xc src tree. [${X11SRCDIR}/xfree/xc] 404 405X11SRCDIR.local The path to the local X11R6 src tree. [${X11SRCDIR}/local] 406 407X11ROOTDIR Root directory of the X11 installation. [/usr/X11R6] 408 409X11BINDIR X11 bin directory. [${X11ROOTDIR}/bin] 410 411X11FONTDIR X11 font directory. [${X11ROOTDIR}/lib/X11/fonts] 412 413X11INCDIR X11 include directory. [${X11ROOTDIR}/include] 414 415X11LIBDIR X11 lib/x11 (config) directory. [${X11ROOTDIR}/lib/X11] 416 417X11MANDIR X11 manual directory. [${X11ROOTDIR}/man] 418 419X11USRLIBDIR X11 library directory. [${X11ROOTDIR}/lib] 420 421STRIPFLAG The flag passed to the install program to cause the binary 422 to be stripped. This is to be used when building your 423 own install script so that the entire system can be made 424 stripped/not-stripped using a single knob. [-s] 425 426COPY The flag passed to the install program to cause the binary 427 to be copied rather than moved. This is to be used when 428 building our own install script so that the entire system 429 can either be installed with copies, or with moves using 430 a single knob. [-c] 431 432Additionally, the following variables may be set by <bsd.own.mk> or in a 433make configuration file to modify the behaviour of the system build 434process (default values are in brackets along with comments, if set by 435<bsd.own.mk>): 436 437USETOOLS Indicates whether the tools specified by ${TOOLDIR} should 438 be used as part of a build in progress. 439 Supported values: 440 441 yes Use the tools from TOOLDIR. 442 Must be set to this if cross-compiling. 443 444 no Do not use the tools from TOOLDIR, but refuse to 445 build native compilation tool components that are 446 version-specific for that tool. 447 448 never Do not use the tools from TOOLDIR, even when 449 building native tool components. This is similar to 450 the traditional NetBSD build method, but does not 451 verify that the compilation tools in use are 452 up-to-date enough in order to build the tree 453 successfully. This may cause build or runtime 454 problems when building the whole NetBSD source tree. 455 456 Default: "yes" if building all or part of a whole NetBSD 457 source tree (detected automatically); "no" otherwise 458 (to preserve traditional semantics of the <bsd.*.mk> 459 make(1) include files). 460 461OBJECT_FMT Object file format. [set to "ELF" on architectures that 462 use ELF -- currently if ${MACHINE_ARCH} is "alpha", 463 "mipsel", "mipseb", "powerpc", "sparc", "sparc64", 464 "i386" and some m68k machines, or set to "a.out" on 465 other architectures]. 466 467TOOLCHAIN_MISSING 468 If not "no", this indicates that the platform being built 469 does not have a working in-tree toolchain. If the 470 ${MACHINE_ARCH} in question falls into this category, 471 TOOLCHAIN_MISSING is conditionally assigned the value "yes". 472 Otherwise, the variable is unconditionally assigned the 473 value "no". 474 If not "no", ${MKBFD}, ${MKGCC}, and ${MKGDB} are 475 unconditionally assigned the value "no". 476 477EXTERNAL_TOOLCHAIN 478 This variable is not directly set by <bsd.own.mk>, but 479 including <bsd.own.mk> is the canonical way to gain 480 access to this variable. The variable should be defined 481 either in the user's environment or in the user's mk.conf 482 file. If defined, this variable indicates the root of 483 an external toolchain which will be used to build the 484 tree. For example, if a platform is a ${TOOLCHAIN_MISSING} 485 platform, EXTERNAL_TOOLCHAIN can be used to re-enable the 486 cross-compile framework. 487 488 If EXTERNAL_TOOLCHAIN is defined, ${MKGCC} is unconditionally 489 assigned the value "no", since the external version of the 490 compiler may not be able to build the library components of 491 the in-tree compiler. 492 493 NOTE: This variable is not yet used in as many places as 494 it should be. Expect the exact semantics of this variable 495 to change in the short term as parts of the cross-compile 496 framework continue to be cleaned up. 497 498<bsd.own.mk> is generally useful when building your own Makefiles so that 499they use the same default owners etc. as the rest of the tree. 500 501 502=-=-=-=-= bsd.dep.mk =-=-=-=-= 503 504The include file <bsd.dep.mk> contains the default targets for building 505.depend files. It creates .d files from entries in SRCS and DPSRCS 506that are C, C++, or Objective C source files, and builds .depend from the 507.d files. All other files in SRCS and all of DPSRCS will be used as 508dependencies for the .d files. In order for this to function correctly, 509it should be .included after all other .mk files and directives that may 510modify SRCS or DPSRCS. It uses the following variables: 511 512SRCS List of source files to build the program. 513 514DPSRCS List of source files which are needed for generating 515 dependencies, but are not needed in ${SRCS}. 516 517 518=-=-=-=-= bsd.files.mk =-=-=-=-= 519 520The include file <bsd.files.mk> handles the FILES variables and is included 521from <bsd.lib.mk> and <bsd.prog.mk>, and uses the following variables: 522 523FILES The list of files to install. 524 525FILESOWN File owner. [${BINOWN}] 526 527FILESGRP File group. [${BINGRP}] 528 529FILESMODE File mode. [${BINMODE}] 530 531FILESDIR The location to install the files. 532 533FILESNAME Optional name to install each file as. 534 535FILESDIR.<fn> The location to install the specific file <fn>. 536 537FILESNAME.<fn> Optional name to install <fn> as. 538 539BUILDSYMLINKS List of two word items: 540 lnsrc lntgt 541 For each lnsrc item, create a symlink named lntgt. 542 The lntgt symlinks are removed by the cleandir target. 543 544 545=-=-=-=-= bsd.gcc.mk =-=-=-=-= 546 547The include file <bsd.gcc.mk> computes various parameters related to GCC 548support libraries. It defines no targets. <bsd.own.mk> MUST be included 549before <bsd.gcc.mk>. 550 551The primary users of <bsd.gcc.mk> are <bsd.prog.mk> and <bsd.lib.mk>, each 552of which need to know where to find certain GCC support libraries. 553 554The behavior of <bsd.gcc.mk> is influenced by the EXTERNAL_TOOLCHAIN variable, 555which is generally set by the user. If EXTERNAL_TOOLCHAIN it set, then 556the compiler is asked where to find the support libraries, otherwise the 557support libraries are found in ${DESTDIR}/usr/lib. 558 559<bsd.gcc.mk> sets the following variables: 560 561_GCC_CRTBEGIN The full path name to crtbegin.o. 562 563_GCC_CRTBEGINS The full path name to crtbeginS.o. 564 565_GCC_CRTEND The full path name to crtend.o. 566 567_GCC_CRTENDS The full path name to crtendS.o. 568 569_GCC_LIBGCCDIR The directory where libgcc.a is located. 570 571 572=-=-=-=-= bsd.inc.mk =-=-=-=-= 573 574The include file <bsd.inc.mk> defines the includes target and uses the 575variables: 576 577INCS The list of include files. 578 579INCSDIR The location to install the include files. 580 581INCSNAME Target name of the include file, if only one; same as 582 FILESNAME, but for include files. 583 584INCSYMLINKS Similar to SYMLINKS in <bsd.links.mk>, except that these 585 are installed in the 'includes' target and not the 586 (much later) 'install' target. 587 588INCSNAME_<file> The name file <file> should be installed as, if not <file>, 589 same as FILESNAME_<file>, but for include files. 590 591 592=-=-=-=-= bsd.info.mk =-=-=-=-= 593 594The include file <bsd.info.mk> is used to generate and install GNU Info 595documentation from respective Texinfo source files. It defines three 596implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the 597following variables: 598 599TEXINFO List of Texinfo source files. Info documentation will 600 consist of single files with the extension replaced by 601 .info. 602 603INFOFLAGS Flags to pass to makeinfo. [] 604 605 606=-=-=-=-= bsd.kernobj.mk =-=-=-=-= 607 608The include file <bsd.kernobj.mk> defines variables related to the 609location of kernel sources and object directories. 610 611KERNSRCDIR Is the location of the top of the kernel src. 612 [${_SRC_TOP_}/sys] 613 614KERNARCHDIR Is the location of the machine dependent kernel sources. 615 [arch/${MACHINE}] 616 617KERNCONFDIR Is where the configuration files for kernels are found. 618 [${KERNSRCDIR}/${KERNARCHDIR}/conf] 619 620KERNOBJDIR Is the kernel build directory. The kernel GENERIC for 621 instance will be compiled in ${KERNOBJDIR}/GENERIC. 622 The default value is 623 ${MAKEOBJDIRPREFIX}${KERNSRCDIR}/${KERNARCHDIR}/compile 624 if it exists or the target 'obj' is being made. 625 Otherwise the default is 626 ${KERNSRCDIR}/${KERNARCHDIR}/compile. 627 628It is important that Makefiles (such as those under src/distrib) that 629wish to find compiled kernels use <bsd.kernobj.mk> and ${KERNOBJDIR} 630rather than make assumptions about the location of the compiled kernel. 631 632 633=-=-=-=-= bsd.kinc.mk =-=-=-=-= 634 635The include file <bsd.kinc.mk> defines the many targets (includes, 636subdirectories, etc.), and is used by kernel makefiles to handle 637include file installation. It is intended to be included alone, by 638kernel Makefiles. It uses similar variables to <bsd.inc.mk>. 639Please see <bsd.kinc.mk> for more details, and keep the documentation 640in that file up to date. 641 642 643=-=-=-=-= bsd.lib.mk =-=-=-=-= 644 645The include file <bsd.lib.mk> has support for building libraries. It has 646the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend, 647includes, install, lint, and tags. Additionally, it has a checkver target 648which checks for installed shared object libraries whose version is greater 649that the version of the source. It has a limited number of suffixes, 650consistent with the current needs of the BSD tree. <bsd.lib.mk> includes 651<bsd.shlib.mk> to get shared library parameters. 652 653It sets/uses the following variables: 654 655LIB The name of the library to build. 656 657LIBDIR Target directory for libraries. 658 659SHLIBINSTALLDIR Target directory for shared libraries if ${USE_SHLIBDIR} 660 is not "no". 661 662USE_SHLIBDIR If not "no", use ${SHLIBINSTALLDIR} instead of ${LIBDIR} 663 as the path to install shared libraries to. 664 USE_SHLIBDIR must be defined before <bsd.own.mk> is included. 665 Default: no 666 667LINTLIBDIR Target directory for lint libraries. 668 669LIBGRP Library group. 670 671LIBOWN Library owner. 672 673LIBMODE Library mode. 674 675LDADD Additional loader objects. 676 677MAN The manual pages to be installed (use a .1 - .9 suffix). 678 679NOCHECKVER_<library> 680NOCHECKVER If set, disables checking for installed shared object 681 libraries with versions greater than the source. A 682 particular library name, without the "lib" prefix, may 683 be appended to the variable name to disable the check for 684 only that library. 685 686SRCS List of source files to build the library. Suffix types 687 .s, .c, and .f are supported. Note, .s files are preferred 688 to .c files of the same name. (This is not the default for 689 versions of make.) 690 691The include file <bsd.lib.mk> includes the file named "../Makefile.inc" 692if it exists, as well as the include file <bsd.man.mk>. 693 694It has rules for building profiled objects; profiled libraries are 695built by default. 696 697Libraries are ranlib'd when made. 698 699 700=-=-=-=-= bsd.links.mk =-=-=-=-= 701 702The include file <bsd.links.mk> handles the LINKS and SYMLINKS variables 703and is included from from <bsd.lib.mk> and <bsd.prog.mk>. 704 705LINKS The list of hard links, consisting of pairs of paths: 706 source-file target-file 707 ${DESTDIR} is prepended to both paths before linking. 708 For example, to link /bin/test and /bin/[, use: 709 LINKS=/bin/test /bin/[ 710 711SYMLINKS The list of symbolic links, consisting of pairs of paths: 712 source-file target-file 713 ${DESTDIR} is only prepended to target-file before linking. 714 For example, to symlink /usr/bin/tar to /bin/tar resulting 715 in ${DESTDIR}/usr/bin/tar -> /bin/tar: 716 SYMLINKS=/bin/tar /usr/bin/tar 717 718 719=-=-=-=-= bsd.man.mk =-=-=-=-= 720 721The include file <bsd.man.mk> handles installing manual pages and their 722links. 723 724It has a two targets: 725 726 maninstall: 727 Install the manual page sources and their links. 728 catinstall: 729 Install the preformatted manual pages and their links. 730 731It sets/uses the following variables: 732 733MANDIR Base path for manual installation. 734 735MANGRP Manual group. 736 737MANOWN Manual owner. 738 739MANMODE Manual mode. 740 741MANSUBDIR Subdirectory under the manual page section, i.e. "/vax" 742 or "/tahoe" for machine specific manual pages. 743 744MAN The manual pages to be installed (use a .1 - .9 suffix). 745 746MLINKS List of manual page links (using a .1 - .9 suffix). The 747 linked-to file must come first, the linked file second, 748 and there may be multiple pairs. The files are soft-linked. 749 750The include file <bsd.man.mk> includes a file named "../Makefile.inc" if 751it exists. 752 753 754=-=-=-=-= bsd.obj.mk =-=-=-=-= 755 756The include file <bsd.obj.mk> defines targets related to the creation 757and use of separated object and source directories. 758 759If an environment variable named MAKEOBJDIRPREFIX is set, make(1) uses 760${MAKEOBJDIRPREFIX}${.CURDIR} as the name of the object directory if 761it exists. Otherwise make(1) looks for the existence of a 762subdirectory (or a symlink to a directory) of the source directory 763into which built targets should be placed. If an environment variable 764named MAKEOBJDIR is set, make(1) uses its value as the name of the 765object directory; failing that, make first looks for a subdirectory 766named "obj.${MACHINE}", and if that doesn't exist, it looks for "obj". 767 768Object directories are not created automatically by make(1) if they 769don't exist; you need to run a separate "make obj". (This will happen 770during a top-level build if "MKOBJDIRS" is set to a value other than 771"no"). When the source directory is a subdirectory of ${BSDSRCDIR} -- 772and this is determined by a simple string prefix comparison -- object 773directories are created in a separate object directory tree, and a 774symlink to the object directory in that tree is created in the source 775directory; otherwise, "make obj" assumes that you're not in the main 776source tree and that it's not safe to use a separate object tree. 777 778Several variables used by <bsd.obj.mk> control exactly what 779directories and links get created during a "make obj": 780 781MAKEOBJDIR If set, this is the component name of the object 782 directory. 783 784OBJMACHINE If this is set but MAKEOBJDIR is not set, creates 785 object directories or links named "obj.${MACHINE}"; 786 otherwise, just creates ones named "obj". 787 788USR_OBJMACHINE If set, and the current directory is a subdirectory of 789 ${BSDSRCDIR}, create object directory in the 790 corresponding subdirectory of ${BSDOBJDIR}.${MACHINE}; 791 otherwise, create it in the corresponding subdirectory 792 of ${BSDOBJDIR} 793 794BUILDID If set, the contents of this variable are appended 795 to the object directory name. If OBJMACHINE is also 796 set, ".${BUILDID}" is added after ".${MACHINE}". 797 798 799=-=-=-=-= bsd.prog.mk =-=-=-=-= 800 801The include file <bsd.prog.mk> handles building programs from one or 802more source files, along with their manual pages. It has a limited number 803of suffixes, consistent with the current needs of the BSD tree. 804<bsd.prog.mk> includes <bsd.shlib.mk> to get shared library parameters. 805 806It has eight targets: 807 808 all: 809 build the program and its manual page. This also 810 creates a GDB initialization file (.gdbinit) in 811 the objdir. The .gdbinit file sets the shared library 812 prefix to ${DESTDIR} to facilitate cross-debugging. 813 clean: 814 remove the program, any object files and the files a.out, 815 Errs, errs, mklog, and ${PROG}.core. 816 cleandir: 817 remove all of the files removed by the target clean, as 818 well as .depend, tags, and any manual pages. 819 `distclean' is a synonym for `cleandir'. 820 depend: 821 make the dependencies for the source files, and store 822 them in the file .depend. 823 includes: 824 install any header files. 825 install: 826 install the program and its manual pages; if the Makefile 827 does not itself define the target install, the targets 828 beforeinstall and afterinstall may also be used to cause 829 actions immediately before and after the install target 830 is executed. 831 lint: 832 run lint on the source files 833 tags: 834 create a tags file for the source files. 835 836It sets/uses the following variables: 837 838BINGRP Binary group. 839 840BINOWN Binary owner. 841 842BINMODE Binary mode. 843 844CLEANFILES Additional files to remove for the clean and cleandir targets. 845 846COPTS Additional flags to the compiler when creating C objects. 847 848COPTS.<fn> Additional flags to the compiler when creating the 849 C objects for <fn>. 850 For <fn>.[ly], "<fn>.c" must be used. 851 852CPUFLAGS Additional flags to the compiler/assembler to select 853 CPU instruction set options, CPU tuning options, etc. 854 855CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>. 856 For <fn>.[ly], "<fn>.c" must be used. 857 858CPPFLAGS Additional flags to the C pre-processor. 859 860CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>. 861 For <fn>.[ly], "<fn>.c" must be used. 862 863GDBINIT List of GDB initialization files to add to "source" 864 directives in the .gdbinit file that is created in the 865 objdir. 866 867LDADD Additional loader objects. Usually used for libraries. 868 For example, to load with the compatibility and utility 869 libraries, use: 870 871 LDADD+=-lutil -lcompat 872 873LDFLAGS Additional loader flags. 874 875LINKS See <bsd.links.mk> 876 877SYMLINKS See <bsd.links.mk> 878 879MAN Manual pages (should end in .1 - .9). If no MAN variable is 880 defined, "MAN=${PROG}.1" is assumed. 881 882PROG The name of the program to build. If not supplied, nothing 883 is built. 884 885PROG_CXX If defined, the name of the program to build. Also 886 causes <bsd.prog.mk> to link the program with the C++ 887 compiler rather than the C compiler. PROG_CXX overrides 888 the value of PROG if PROG is also set. 889 890PROGNAME The name that the above program will be installed as, if 891 different from ${PROG}. 892 893SRCS List of source files to build the program. If SRCS is not 894 defined, it's assumed to be ${PROG}.c. 895 896DPSRCS List of source files which are needed for generating 897 dependencies, but are not needed in ${SRCS}. 898 899DPADD Additional dependencies for the program. Usually used for 900 libraries. For example, to depend on the compatibility and 901 utility libraries use: 902 903 DPADD+=${LIBCOMPAT} ${LIBUTIL} 904 905 The following libraries are predefined for DPADD: 906 907 LIBCRT0?= ${DESTDIR}/usr/lib/crt0.o 908 LIBBZ2?= ${DESTDIR}/usr/lib/libbz2.a 909 LIBC?= ${DESTDIR}/usr/lib/libc.a 910 LIBC_PIC?= ${DESTDIR}/usr/lib/libc_pic.a 911 LIBCDK?= ${DESTDIR}/usr/lib/libcdk.a 912 LIBCOM_ERR?= ${DESTDIR}/usr/lib/libcom_err.a 913 LIBCOMPAT?= ${DESTDIR}/usr/lib/libcompat.a 914 LIBCRYPT?= ${DESTDIR}/usr/lib/libcrypt.a 915 LIBCRYPTO?= ${DESTDIR}/usr/lib/libcrypto.a 916 LIBCRYPTO_IDEA?=${DESTDIR}/usr/lib/libcrypto_idea.a 917 LIBCRYPTO_MDC2?=${DESTDIR}/usr/lib/libcrypto_mdc2.a 918 LIBCRYPTO_RC5?= ${DESTDIR}/usr/lib/libcrypto_rc5.a 919 LIBCURSES?= ${DESTDIR}/usr/lib/libcurses.a 920 LIBDBM?= ${DESTDIR}/usr/lib/libdbm.a 921 LIBDES?= ${DESTDIR}/usr/lib/libdes.a 922 LIBEDIT?= ${DESTDIR}/usr/lib/libedit.a 923 LIBEVENT?= ${DESTDIR}/usr/lib/libevent.a 924 LIBFORM?= ${DESTDIR}/usr/lib/libform.a 925 LIBGCC?= ${DESTDIR}/usr/lib/libgcc.a 926 LIBGNUMALLOC?= ${DESTDIR}/usr/lib/libgnumalloc.a 927 LIBGSSAPI?= ${DESTDIR}/usr/lib/libgssapi.a 928 LIBHDB?= ${DESTDIR}/usr/lib/libhdb.a 929 LIBINTL?= ${DESTDIR}/usr/lib/libintl.a 930 LIBIPSEC?= ${DESTDIR}/usr/lib/libipsec.a 931 LIBKADM?= ${DESTDIR}/usr/lib/libkadm.a 932 LIBKADM5CLNT?= ${DESTDIR}/usr/lib/libkadm5clnt.a 933 LIBKADM5SRV?= ${DESTDIR}/usr/lib/libkadm5srv.a 934 LIBKAFS?= ${DESTDIR}/usr/lib/libkafs.a 935 LIBKDB?= ${DESTDIR}/usr/lib/libkdb.a 936 LIBKRB?= ${DESTDIR}/usr/lib/libkrb.a 937 LIBKRB5?= ${DESTDIR}/usr/lib/libkrb5.a 938 LIBKSTREAM?= ${DESTDIR}/usr/lib/libkstream.a 939 LIBKVM?= ${DESTDIR}/usr/lib/libkvm.a 940 LIBL?= ${DESTDIR}/usr/lib/libl.a 941 LIBM?= ${DESTDIR}/usr/lib/libm.a 942 LIBMENU?= ${DESTDIR}/usr/lib/libmenu.a 943 LIBOBJC?= ${DESTDIR}/usr/lib/libobjc.a 944 LIBOSSAUDIO?= ${DESTDIR}/usr/lib/libossaudio.a 945 LIBPCAP?= ${DESTDIR}/usr/lib/libpcap.a 946 LIBPCI?= ${DESTDIR}/usr/lib/libpci.a 947 LIBPMC?= ${DESTDIR}/usr/lib/libpmc.a 948 LIBPOSIX?= ${DESTDIR}/usr/lib/libposix.a 949 LIBPTHREAD?= ${DESTDIR}/usr/lib/libpthread.a 950 LIBPTHREAD_DBG?=${DESTDIR}/usr/lib/libpthread_dbg.a 951 LIBRESOLV?= ${DESTDIR}/usr/lib/libresolv.a 952 LIBRMT?= ${DESTDIR}/usr/lib/librmt.a 953 LIBROKEN?= ${DESTDIR}/usr/lib/libroken.a 954 LIBRPCSVC?= ${DESTDIR}/usr/lib/librpcsvc.a 955 LIBRT?= ${DESTDIR}/usr/lib/librt.a 956 LIBSKEY?= ${DESTDIR}/usr/lib/libskey.a 957 LIBSL?= ${DESTDIR}/usr/lib/libsl.a 958 LIBSS?= ${DESTDIR}/usr/lib/libss.a 959 LIBSSL?= ${DESTDIR}/usr/lib/libssl.a 960 LIBSTDCXX?= ${DESTDIR}/usr/lib/libstdc++.a 961 LIBTERMCAP?= ${DESTDIR}/usr/lib/libtermcap.a 962 LIBUSBHID?= ${DESTDIR}/usr/lib/libusbhid.a 963 LIBUTIL?= ${DESTDIR}/usr/lib/libutil.a 964 LIBWRAP?= ${DESTDIR}/usr/lib/libwrap.a 965 LIBY?= ${DESTDIR}/usr/lib/liby.a 966 LIBZ?= ${DESTDIR}/usr/lib/libz.a 967 968SHAREDSTRINGS If defined, a new .c.o rule is used that results in shared 969 strings, using xstr(1). Note that this will not work with 970 parallel makes. 971 972STRIPFLAG The flag passed to the install program to cause the binary 973 to be stripped. 974 975SUBDIR A list of subdirectories that should be built as well. 976 Each of the targets will execute the same target in the 977 subdirectories. 978 979SCRIPTS A list of interpreter scripts [file.{sh,csh,pl,awk,...}]. 980 These are installed exactly like programs. 981 982SCRIPTSNAME The name that the above program will be installed as, if 983 different from ${SCRIPTS}.

It has the same eight targets as <bsd.prog.mk>: all, 1069clean, cleandir, depend, includes, install, lint, and tags. For all of 1070the directories listed in ${SUBDIR}, the specified directory will be 1071visited and the target made. There is also a default target which allows 1072the command "make subdir" where subdir is any directory listed in ${SUBDIR}. 1073 1074As a special case, the use of a token .WAIT as an entry in SUBDIR acts 1075as a synchronization barrier when multiple make jobs are run; subdirs 1076before the .WAIT must complete before any subdirs after .WAIT are 1077started. See make(1) for some caveats on use of .WAIT and other 1078special sources. 1079 1080 1081=-=-=-=-= bsd.sys.mk =-=-=-=-= 1082 1083The include file <bsd.sys.mk> is used by <bsd.prog.mk> and 1084<bsd.lib.mk>.
