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:
1.52.4.1! wrstuden 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, ...

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

289: them in the file .depend.
1.16 jtc 290: includes:
291: install any header files.
1.1 cgd 292: install:
293: install the program and its manual pages; if the Makefile
294: does not itself define the target install, the targets
295: beforeinstall and afterinstall may also be used to cause
296: actions immediately before and after the install target
297: is executed.
298: lint:
299: run lint on the source files
300: tags:
301: create a tags file for the source files.

323: LDFLAGS Additional loader flags.
324:
325: LINKS The list of binary links; should be full pathnames, the
326: linked-to file coming first, followed by the linked
327: file. The files are hard-linked. For example, to link
328: /bin/test and /bin/[, use:
329:
330: LINKS= ${DESTDIR}/bin/test ${DESTDIR}/bin/[
1.19 perry 331:
332: SYMLINKS The list of symbolic links; should be full pathnames.

334: automatically included in the link.
1.1 cgd 335:
1.15 cgd 336: MAN Manual pages (should end in .1 - .9). If no MAN variable is
1.8 cgd 337: defined, "MAN=${PROG}.1" is assumed.

1.1 cgd 346: defined, it's assumed to be ${PROG}.c.
347:
348: DPADD Additional dependencies for the program. Usually used for
349: libraries. For example, to depend on the compatibility and
350: utility libraries use:
351:
1.5 jtc 352: DPADD+=${LIBCOMPAT} ${LIBUTIL}
1.1 cgd 353:

1.13 christos 492: The include file <bsd.sys.mk> is used by <bsd.prog.mk> and
1.14 cgd 493: <bsd.lib.mk>. It contains overrides that are used when building
494: the NetBSD source tree. For instance, if "PARALLEL" is defined by
495: the program/library Makefile, it includes a set of rules for lex and
496: yacc that allow multiple lex and yacc targets to be built in parallel.

500: The include file <bsd.lib.mk> has support for building libraries. It has
1.16 jtc 501: the same eight targets as <bsd.prog.mk>: all, clean, cleandir, depend,
1.44 erh 502: includes, install, lint, and tags. Additionally, it has a checkver target
503: which checks for installed shared object libraries whose version is greater
504: that the version of the source. It has a limited number of suffixes,
1.16 jtc 505: consistent with the current needs of the BSD tree.
1.1 cgd 506:
507: It sets/uses the following variables:
1.10 cgd 508:
509: LIB The name of the library to build.
1.1 cgd 510:
511: LIBDIR Target directory for libraries.
512:
513: LINTLIBDIR Target directory for lint libraries.
514:
515: LIBGRP Library group.
516:
517: LIBOWN Library owner.
518:
519: LIBMODE Library mode.
520:
521: LDADD Additional loader objects.
522:
1.15 cgd 523: MAN The manual pages to be installed (use a .1 - .9 suffix).
1.47 tv 524:
525: MKLINKLIB If "no", act as "MKPICINSTALL=no MKPROFILE=no".
526: Also:
527: - don't install the .a libraries
528: - don't install _pic.a libraries on PIC systems
529: - don't build .a libraries on PIC systems
530: - don't install the .so symlink on ELF systems
531: I.e, only install the shared library (and the .so.major
532: symlink on ELF).
1.44 erh 533:
1.52.4.1! wrstuden 534: MKPICLIB If "no", don't build _pic.a libraries, and build the
! 535: shared object libraries from the .a libraries. A
! 536: symlink is installed in ${DESTDIR}/usr/lib for the
! 537: _pic.a library pointing to the .a library.
! 538:
1.44 erh 539: NOCHECKVER_<library>
540: NOCHECKVER If set, disables checking for installed shared object
541: libraries with versions greater than the source. A
542: particular library name, without the "lib" prefix, may
543: be appended to the variable name to disable the check for
544: only that library.
1.1 cgd 545:
546: SRCS List of source files to build the library. Suffix types
547: .s, .c, and .f are supported. Note, .s files are preferred
548: to .c files of the same name. (This is not the default for
549: versions of make.)
550:
551: The include file <bsd.lib.mk> includes the file named "../Makefile.inc"
552: if it exists, as well as the include file <bsd.man.mk>.
553:
554: It has rules for building profiled objects; profiled libraries are
555: built by default.

561: The include file <bsd.crypto.mk> contains variables related to building
562: cryptography support into the system.
563:
564: It has no targets.
565:
566: In order to get system-specific crypto configuration parameters,
567: bsd.crypto.mk will include <bsd.own.mk>, which in turn will include
568: the configuration file specified by the "MAKECONF" variable. See
569: the <bsd.own.mk> section for more information.
570:
571: bsd.crypto.mk requires the "SRCTOP" variable to be defined before
572: inclusion. This variable contains the relative path to the top of
573: the source tree, with no trailing '/'.
574:
575: The variable "CRYPTOBASE" may be set by the user to select which
576: cryptography code base will be used when building the system. If
577: CRYPTOBASE is set to "none", no cryptography support will be built
578: into the system. CRYPTOBASE should be set to the name of the crypto
579: sub-tree in the SRCTOP directory. If CRYPTOBASE is not set,
580: bsd.crypto.mk will use the following algorithm to set the variable:
581:
582: .if exists(${SRCTOP}/crypto-us)
583: CRYPTOBASE=crypto-us
584: .elif exists(${SRCTOP}/crypto-intl)
585: CRYPTOBASE=crypto-intl
586: .else
587: undef CRYPTOBASE
588: .endif
589:
590: Note that it is legal for the user to set CRYPTOBASE to a relative
591: path outside of the source directory. For example:
592:
593: CRYPTOPATH= ../cryptosrc-intl/crypto-intl
594:
595: If CRYPTOBASE is set and not set to "none", bsd.crypto.mk will use
596: CRYPTOBASE to set the "CRYPTOPATH" variable. CRYPTOPATH is set to
597: the value "${SRCTOP}/${CRYPTOBASE}".
598:
599: Once CRYPTOPATH is set by bsd.crypto.mk, it checks to see if the
600: path actually exists. If it does not exist, the variable is undefined.
601: Program and library Makefiles may key off the definition of CRYPTOPATH
602: to determine if cryptography support is to be included in that program.
603: For example, a typical program Makefile should do the following:
604:
605: SRCTOP= ../..
606: .include <bsd.crypto.mk>
607:
608: PROG= login
609: SRCS= login.c
610: .
611: .
612: .
613: .if defined(CRYPTOPATH)
1.51 mrg 614: .sinclude "${CRYPTOPATH}/usr.bin/login/Makefile.frag"
1.50 thorpej 615: .endif
616:
1.51 mrg 617: The Makefile.frag included (if it exists) will now influence the build
618: of the login(1) program, specifying additional source files, libraries,
619: and CPP flags.
1.50 thorpej 620:
621: The "EXPORTABLE_SYSTEM" variable, if set, causes CRYPTOBASE to be set
622: to "none". This is for compatibilty with older NetBSD build environments.

! 625:
! 626: The include file <bsd.obj.mk> defines targets related to the creation
! 627: and use of separated object and source directories.
! 628:
! 629: make(1) looks for the existance of a subdirectory (or a symlink to a
! 630: directory) of the source directory into which built targets should be
! 631: placed. If an environment variable named MAKEOBJDIR is set, make(1)
! 632: uses its value as the name of the object directory; failing that, make
! 633: first looks for a subdirectory named "obj.${MACHINE}", and if that
! 634: doesn't exist, it looks for "obj".
! 635:
! 636: Object directories are not created automatically by make(1) if they
! 637: don't exist; you need to run a separate "make obj". (This will happen
! 638: during a top-level build if "MKOBJDIRS" is set to a value other than
! 639: "no"). When the source directory is a subdirectory of ${BSDSRCDIR},
! 640: object directories are created in a separate object directory tree,
! 641: and a symlink to the object directory in that tree is created in the
! 642: source directory.
! 643:
! 644: Several variables used by <bsd.obj.mk> control exactly what
! 645: directories and links get created during a "make obj":
! 646:
! 647: MAKEOBJDIR If set, this is the component name of the object
! 648: directory.
! 649:
! 650: OBJMACHINE If this is set but MAKEOBJDIR is not set, creates
! 651: object directories or links named "obj.${MACHINE}";
! 652: otherwise, just creates ones named "obj".
! 653:
! 654: USR_OBJMACHINE If set, and the current directory is a subdirectory of
! 655: ${BSDSRCDIR}, create object directory in the
! 656: corresponding subdirectory of ${BSDOBJDIR}.${MACHINE};
! 657: otherwise, create it in the corresponding subdirectory
! 658: of ${BSDOBJDIR}
