1.1 cgd 3:
4: This is the README file for the new make "include" files for the BSD
5: source tree. The files are installed in /usr/share/mk, and are, by
1.11 jtc 6: convention, named with the suffix ".mk".
1.1 cgd 7:
8: Note, this file is not intended to replace reading through the .mk
9: files for anything tricky.

12:
13: RANDOM THINGS WORTH KNOWING:
14:
15: The files are simply C-style #include files, and pretty much behave like
16: you'd expect. The syntax is slightly different in that a single '.' is
17: used instead of the hash mark, i.e. ".include <bsd.prog.mk>".
18:
19: One difference that will save you lots of debugging time is that inclusion
20: of the file is normally done at the *end* of the Makefile. The reason for
21: this is because .mk files often modify variables and behavior based on the
22: values of variables set in the Makefile. To make this work, remember that
23: the 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:
30: the command "make a" will echo "a". To make things confusing, the SECOND
31: variable 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:
39: the command "make b" will echo "bar". This is for compatibility with the
40: way the V7 make behaved.
41:
42: It's fairly difficult to make the BSD .mk files work when you're building
43: multiple programs in a single directory. It's a lot easier split up the
44: programs than to deal with the problem. Most of the agony comes from making
1.36 ross 45: the "obj" directory stuff work right, not because we switched to a new version
1.1 cgd 46: of make. So, don't get mad at us, figure out a better way to handle multiple
47: architectures so we can quit using the symbolic link stuff. (Imake doesn't
48: count.)
49:
50: The file .depend in the source directory is expected to contain dependencies
51: for the source files. This file is read automatically by make after reading
52: the Makefile.
53:
54: The variable DESTDIR works as before. It's not set anywhere but will change
55: the tree where the file gets installed.
56:
57: The profiled libraries are no longer built in a different directory than
58: the regular libraries. A new suffix, ".po", is used to denote a profiled
1.21 christos 59: object, and ".so" denotes a shared (position-independent) object.
60:
1.45 lukem 61: The following variables that control how things are made/installed that
1.47 tv 62: are not set by default. These should not be set by Makefiles; they're for
63: the user to define in MAKECONF (see bsd.own.mk, below) or on the make(1)
64: command line:
1.21 christos 65:
1.45 lukem 66: BUILD If defined, 'make install' checks that the targets in the
67: source directories are up-to-date and remakes them if they
1.21 christos 68: are out of date, instead of blindly trying to install
69: out of date or non-existant targets.
70:
1.45 lukem 71: UPDATE If defined, 'make install' only installs targets that are
72: more recently modified in the source directories that their
73: installed counterparts.
1.52 simonb 74:
75: UNPRIVILEGED If defined, don't set the owner/group/mode when installing
76: files or directories. This allows a non-root "make install".
1.45 lukem 77:
78: MKCATPAGES If "no", don't build or install the catman pages.
79:
80: MKDOC If "no", don't build or install the documentation.
81:
1.47 tv 82: MKINFO If "no", don't build or install Info documentation from
83: Texinfo source files.
1.45 lukem 84:
85: MKLINT If "no", don't build or install the lint libraries.
86:
87: MKMAN If "no", don't build or install the man or catman pages.
1.46 lukem 88: Also acts as "MKCATPAGES=no"
1.45 lukem 89:
90: MKNLS If "no", don't build or install the NLS files.
91:
1.55 sommerfe 92: MKOBJ If "no", don't enable the rule which creates objdirs.
93: "yes" by default.
94:
95: MKOBJDIRS If "no", don't create objdirs during a "make build".
96: "no" by default.
1.45 lukem 97:
98: MKPIC If "no", don't build or install shared libraries.
99:
100: MKPICINSTALL If "no", don't install the *_pic.a libraries.
101:
102: MKPROFILE If "no", don't build or install the profiling libraries.
103:
1.48 lukem 104: MKSHARE If "no", act as "MKCATPAGES=no MKDOC=no MKINFO=no MKMAN=no
105: MKNLS=no". I.e, don't build catman pages, documentation,
106: Info documentation, man pages, NLS files, ...

1.33 jonathan 268:
1.1 cgd 269:
1.17 thorpej 270: bsd.own.mk is generally useful when building your own Makefiles so that

272:
273: =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
274:
275: The include file <bsd.prog.mk> handles building programs from one or
276: more source files, along with their manual pages. It has a limited number
277: of suffixes, consistent with the current needs of the BSD tree.
278:
1.16 jtc 279: It has eight targets:
1.1 cgd 280:
281: all:
282: build the program and its manual page
283: clean:
284: remove the program, any object files and the files a.out,

1.1 cgd 286: cleandir:
287: remove all of the files removed by the target clean, as
288: well as .depend, tags, and any manual pages.
1.42 lukem 289: `distclean' is a synonym for `cleandir'.
1.1 cgd 290: depend:
291: make the dependencies for the source files, and store
292: them in the file .depend.
1.16 jtc 293: includes:
294: install any header files.
1.1 cgd 295: install:
296: install the program and its manual pages; if the Makefile
297: does not itself define the target install, the targets
298: beforeinstall and afterinstall may also be used to cause
299: actions immediately before and after the install target
300: is executed.
301: lint:
302: run lint on the source files
303: tags:
304: create a tags file for the source files.
305:
306: It sets/uses the following variables:
307:
308: BINGRP Binary group.
309:
310: BINOWN Binary owner.
311:
312: BINMODE Binary mode.
313:
314: CLEANFILES Additional files to remove for the clean and cleandir targets.
315:

1.35 lukem 317:
318: CPPFLAGS Additional flags to the C pre-processor
1.1 cgd 319:
320: LDADD Additional loader objects. Usually used for libraries.
321: For example, to load with the compatibility and utility
322: libraries, use:

1.1 cgd 325:
326: LDFLAGS Additional loader flags.
327:
328: LINKS The list of binary links; should be full pathnames, the
329: linked-to file coming first, followed by the linked
330: file. The files are hard-linked. For example, to link
331: /bin/test and /bin/[, use:
332:
333: LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[
1.19 perry 334:
335: SYMLINKS The list of symbolic links; should be full pathnames.
1.20 perry 336: Syntax is identical to LINKS. Note that DESTDIR is not
337: automatically included in the link.
1.1 cgd 338:
1.15 cgd 339: MAN Manual pages (should end in .1 - .9). If no MAN variable is
1.8 cgd 340: defined, "MAN=${PROG}.1" is assumed.

346: different from ${PROG}.
347:
1.37 tv 348: SRCS List of source files to build the program. If SRCS is not
1.1 cgd 349: defined, it's assumed to be ${PROG}.c.
350:
351: DPADD Additional dependencies for the program. Usually used for
352: libraries. For example, to depend on the compatibility and
353: utility libraries use:
354:
1.5 jtc 355: DPADD+=${LIBCOMPAT} ${LIBUTIL}
1.1 cgd 356:
357: The following libraries are predefined for DPADD:

1.47 tv 478: The include file <bsd.info.mk> is used to generate and install GNU Info
479: documentation from respective Texinfo source files. It defines three
480: implicit targets (.txi.info, .texi.info, and .texinfo.info), and uses the
481: following variables:
482:
483: TEXINFO List of Texinfo source files. Info documentation will
484: consist of single files with the extension replaced by
485: .info.
486:
487: INFOFLAGS Flags to pass to makeinfo. []
488:
489: INSTALL_INFO Name of install-info program. [install-info]

1.13 christos 495: The include file <bsd.sys.mk> is used by <bsd.prog.mk> and
1.14 cgd 496: <bsd.lib.mk>. It contains overrides that are used when building
497: the NetBSD source tree. For instance, if "PARALLEL" is defined by
498: the program/library Makefile, it includes a set of rules for lex and
499: yacc that allow multiple lex and yacc targets to be built in parallel.

503: The include file <bsd.lib.mk> has support for building libraries. It has
1.16 jtc 504: the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1.44 erh 505: includes, install, lint, and tags. Additionally, it has a checkver target
506: which checks for installed shared object libraries whose version is greater
507: that the version of the source. It has a limited number of suffixes,
1.16 jtc 508: consistent with the current needs of the BSD tree.
1.1 cgd 509:
510: It sets/uses the following variables:
1.10 cgd 511:
512: LIB The name of the library to build.
1.1 cgd 513:
514: LIBDIR Target directory for libraries.
515:
516: LINTLIBDIR Target directory for lint libraries.
517:
518: LIBGRP Library group.
519:
520: LIBOWN Library owner.
521:
522: LIBMODE Library mode.
523:
524: LDADD Additional loader objects.
525:
1.15 cgd 526: MAN The manual pages to be installed (use a .1 - .9 suffix).
1.47 tv 527:
528: MKLINKLIB If "no", act as "MKPICINSTALL=no MKPROFILE=no".
529: Also:
530: - don't install the .a libraries
531: - don't install _pic.a libraries on PIC systems
532: - don't build .a libraries on PIC systems
533: - don't install the .so symlink on ELF systems
534: I.e, only install the shared library (and the .so.major
535: symlink on ELF).
1.54 simonb 536:
537: MKPICLIB If "no", don't build _pic.a libraries, and build the
538: shared object libraries from the .a libraries. A
539: symlink is installed in ${DESTDIR}/usr/lib for the
540: _pic.a library pointing to the .a library.
1.44 erh 541:
542: NOCHECKVER_<library>
543: NOCHECKVER If set, disables checking for installed shared object
544: libraries with versions greater than the source. A
545: particular library name, without the "lib" prefix, may
546: be appended to the variable name to disable the check for
547: only that library.
1.1 cgd 548:
549: SRCS List of source files to build the library. Suffix types
550: .s, .c, and .f are supported. Note, .s files are preferred
551: to .c files of the same name. (This is not the default for
552: versions of make.)
553:
554: The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
555: if it exists, as well as the include file <bsd.man.mk>.
556:
557: It has rules for building profiled objects; profiled libraries are
558: built by default.
559:
1.4 cgd 560: Libraries are ranlib'd when made.

564: The include file <bsd.crypto.mk> contains variables related to building
565: cryptography support into the system.
566:
567: It has no targets.
568:
569: In order to get system-specific crypto configuration parameters,
570: bsd.crypto.mk will include <bsd.own.mk>, which in turn will include
571: the configuration file specified by the "MAKECONF" variable. See
572: the <bsd.own.mk> section for more information.
573:
574: bsd.crypto.mk requires the "SRCTOP" variable to be defined before
575: inclusion. This variable contains the relative path to the top of
576: the source tree, with no trailing '/'.
577:
578: The variable "CRYPTOBASE" may be set by the user to select which
579: cryptography code base will be used when building the system. If
580: CRYPTOBASE is set to "none", no cryptography support will be built
581: into the system. CRYPTOBASE should be set to the name of the crypto
582: sub-tree in the SRCTOP directory. If CRYPTOBASE is not set,
583: bsd.crypto.mk will use the following algorithm to set the variable:
584:
585: .if exists(${SRCTOP}/crypto-us)
586: CRYPTOBASE=crypto-us
587: .elif exists(${SRCTOP}/crypto-intl)
588: CRYPTOBASE=crypto-intl
589: .else
590: undef CRYPTOBASE
591: .endif
592:
593: Note that it is legal for the user to set CRYPTOBASE to a relative
594: path outside of the source directory. For example:
595:
1.57 drochner 596: CRYPTOBASE= ../cryptosrc-intl/crypto-intl
1.50 thorpej 597:
598: If CRYPTOBASE is set and not set to "none", bsd.crypto.mk will use
599: CRYPTOBASE to set the "CRYPTOPATH" variable. CRYPTOPATH is set to
600: the value "${SRCTOP}/${CRYPTOBASE}".
601:
602: Once CRYPTOPATH is set by bsd.crypto.mk, it checks to see if the
603: path actually exists. If it does not exist, the variable is undefined.
604: Program and library Makefiles may key off the definition of CRYPTOPATH
605: to determine if cryptography support is to be included in that program.
606: For example, a typical program Makefile should do the following:
607:
608: SRCTOP= ../..
609: .include <bsd.crypto.mk>
610:
611: PROG= login
612: SRCS= login.c
613: .
614: .
615: .
616: .if defined(CRYPTOPATH)
1.51 mrg 617: .sinclude "${CRYPTOPATH}/usr.bin/login/Makefile.frag"
1.50 thorpej 618: .endif
619:
1.51 mrg 620: The Makefile.frag included (if it exists) will now influence the build
621: of the login(1) program, specifying additional source files, libraries,
622: and CPP flags.
1.50 thorpej 623:
624: The "EXPORTABLE_SYSTEM" variable, if set, causes CRYPTOBASE to be set
625: to "none". This is for compatibilty with older NetBSD build environments.

628:
629: The include file <bsd.obj.mk> defines targets related to the creation
630: and use of separated object and source directories.
631:
632: make(1) looks for the existance of a subdirectory (or a symlink to a
633: directory) of the source directory into which built targets should be
634: placed. If an environment variable named MAKEOBJDIR is set, make(1)
635: uses its value as the name of the object directory; failing that, make
636: first looks for a subdirectory named "obj.${MACHINE}", and if that
637: doesn't exist, it looks for "obj".
638:
639: Object directories are not created automatically by make(1) if they
640: don't exist; you need to run a separate "make obj". (This will happen
641: during a top-level build if "MKOBJDIRS" is set to a value other than
1.58 sommerfe 642: "no"). When the source directory is a subdirectory of ${BSDSRCDIR} --
643: and this is determined by a simple string prefix comparison -- object
644: directories are created in a separate object directory tree, and a
645: symlink to the object directory in that tree is created in the source
646: directory; otherwise, "make obj" assumes that you're not in the main
647: source tree and that it's not safe to use a separate object tree.
1.56 sommerfe 648:
649: Several variables used by <bsd.obj.mk> control exactly what
650: directories and links get created during a "make obj":
651:
652: MAKEOBJDIR If set, this is the component name of the object
653: directory.
654:
655: OBJMACHINE If this is set but MAKEOBJDIR is not set, creates
656: object directories or links named "obj.${MACHINE}";
657: otherwise, just creates ones named "obj".
658:
659: USR_OBJMACHINE If set, and the current directory is a subdirectory of
660: ${BSDSRCDIR}, create object directory in the
661: corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
662: otherwise, create it in the corresponding subdirectory
663: of ${BSDOBJDIR}
