Makefile revision 1.201
1 # $NetBSD: Makefile,v 1.201 2003/04/03 00:41:50 mycroft Exp $ 2 3 # 4 # This is the top-level makefile for building NetBSD. For an outline of 5 # how to build a snapshot or release, as well as other release engineering 6 # information, see http://www.netbsd.org/developers/releng/index.html 7 # 8 # Not everything you can set or do is documented in this makefile. In 9 # particular, you should review the files in /usr/share/mk (especially 10 # bsd.README) for general information on building programs and writing 11 # Makefiles within this structure, and see the comments in src/etc/Makefile 12 # for further information on installation and release set options. 13 # 14 # Variables listed below can be set on the make command line (highest 15 # priority), in /etc/mk.conf (middle priority), or in the environment 16 # (lowest priority). 17 # 18 # Variables: 19 # DESTDIR is the target directory for installation of the compiled 20 # software. It defaults to /. Note that programs are built against 21 # libraries installed in DESTDIR. 22 # MKMAN, if set to `no', will prevent building of manual pages. 23 # MKOBJDIRS, if not set to `no', will build object directories at 24 # an appropriate point in a build. 25 # MKSHARE, if set to `no', will prevent building and installing 26 # anything in /usr/share. 27 # UPDATE, if defined, will avoid a `make cleandir' at the start of 28 # `make build', as well as having the effects listed in 29 # /usr/share/mk/bsd.README. 30 # NOCLEANDIR, if defined, will avoid a `make cleandir' at the start 31 # of the `make build'. 32 # NOINCLUDES will avoid the `make includes' usually done by `make build'. 33 # 34 # Targets: 35 # build: 36 # Builds a full release of NetBSD in DESTDIR, except for the 37 # /etc configuration files. 38 # If BUILD_DONE is set, this is an empty target. 39 # distribution: 40 # Builds a full release of NetBSD in DESTDIR, including the /etc 41 # configuration files. 42 # buildworld: 43 # As per `make distribution', except that it ensures that DESTDIR 44 # is not the root directory. 45 # installworld: 46 # Install the distribution from DESTDIR to INSTALLWORLDDIR (which 47 # defaults to the root directory). Ensures that INSTALLWORLDDIR 48 # is the not root directory if cross compiling. 49 # release: 50 # Does a `make build', and then tars up the DESTDIR files 51 # into RELEASEDIR/${MACHINE}, in release(7) format. 52 # (See etc/Makefile for more information on this.) 53 # regression-tests: 54 # Runs the regression tests in "regress" on this host. 55 # 56 # Targets invoked by `make build,' in order: 57 # cleandir: cleans the tree. 58 # obj: creates object directories. 59 # do-tools: builds host toolchain. 60 # do-distrib-dirs: creates the distribution directories. 61 # includes: installs include files. 62 # do-lib-csu: builds and installs prerequisites from lib/csu. 63 # do-lib-libc: builds and installs prerequisites from lib/libc. 64 # do-lib-libcrypt: builds and installs prerequisites from lib/libcrypt. 65 # do-lib: builds and installs prerequisites from lib. 66 # do-gnu-lib: builds and installs prerequisites from gnu/lib. 67 # do-ld.so: builds and installs prerequisites from libexec/ld.*_so. 68 # do-build: builds and installs the entire system. 69 # 70 71 .if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 72 .MAKEFLAGS: -m ${.CURDIR}/share/mk 73 .endif 74 75 # 76 # If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 77 # not be the top level objdir, because "make obj" can happen in the *middle* 78 # of "make build" (long after <bsd.own.mk> is calculated it).
