Makefile revision 1.270
1 # $NetBSD: Makefile,v 1.270 2009/04/23 09:43:49 apb 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 `no', will prevent building of manual pages. 23 # MKOBJDIRS, if not `no', will build object directories at 24 # an appropriate point in a build. 25 # MKSHARE, if `no', will prevent building and installing 26 # anything in /usr/share. 27 # MKUPDATE, if not `no', 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 # See mk.conf(5) for more details. 35 # 36 # 37 # Targets: 38 # build: 39 # Builds a full release of NetBSD in DESTDIR, except for the 40 # /etc configuration files. 41 # If BUILD_DONE is set, this is an empty target. 42 # distribution: 43 # Builds a full release of NetBSD in DESTDIR, including the /etc 44 # configuration files. 45 # buildworld: 46 # As per `make distribution', except that it ensures that DESTDIR 47 # is not the root directory. 48 # installworld: 49 # Install the distribution from DESTDIR to INSTALLWORLDDIR (which 50 # defaults to the root directory). Ensures that INSTALLWORLDDIR 51 # is the not root directory if cross compiling. 52 # release: 53 # Does a `make distribution', and then tars up the DESTDIR files 54 # into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format. 55 # (See etc/Makefile for more information on this.) 56 # regression-tests: 57 # Runs the regression tests in "regress" on this host. 58 # sets: 59 # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets 60 # from ${DESTDIR} 61 # sourcesets: 62 # Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR} 63 # syspkgs: 64 # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs 65 # from ${DESTDIR} 66 # iso-image: 67 # Create CD-ROM image in RELEASEDIR/iso. 68 # RELEASEDIR must already have been populated by `make release' 69 # or equivalent. 70 # iso-image-source: 71 # Create CD-ROM image with source in RELEASEDIR/iso. 72 # RELEASEDIR must already have been populated by 73 # `make release sourcesets' or equivalent. 74 # 75 # Targets invoked by `make build,' in order: 76 # cleandir: cleans the tree. 77 # do-top-obj: creates the top level object directory. 78 # do-tools-obj: creates object directories for the host toolchain. 79 # do-tools: builds host toolchain. 80 # obj: creates object directories. 81 # do-distrib-dirs: creates the distribution directories. 82 # includes: installs include files. 83 # do-tools-compat: builds the "libnbcompat" library; needed for some 84 # random host tool programs in the source tree. 85 # do-lib-csu: builds and installs prerequisites from lib/csu. 86 # do-libgcc: builds and installs prerequisites from 87 # gnu/lib/crtstuff${LIBGCC_EXT} (if necessary) and 88 # gnu/lib/libgcc${LIBGCC_EXT}. 89 # do-libpcc: builds and install prerequisites from 90 # external/bsd/pcc/crtstuff and external/bsd/pcc/libpcc. 91 # do-lib-libc: builds and installs prerequisites from lib/libc. 92 # do-lib: builds and installs prerequisites from lib. 93 # do-gnu-lib: builds and installs prerequisites from gnu/lib. 94 # do-external-lib: builds and installs prerequisites from external/lib. 95 # do-sys-rump-fs-lib: builds and installs prerequisites from sys/rump/fs/lib 96 # do-sys-rump-net-lib: builds and installs prerequisites from sys/rump/net/lib 97 # do-sys-modules: builds and installs kernel modules (used by rump binaries) 98 # do-ld.so: builds and installs prerequisites from libexec/ld.*_so. 99 # do-compat-lib-csu: builds and installs prerequisites from compat/lib/csu 100 # if ${MKCOMPAT} != "no". 101 # do-compat-libgcc: builds and installs prerequisites from 102 # compat/gnu/lib/crtstuff${LIBGCC_EXT} (if necessary) and 103 # compat/gnu/lib/libgcc${LIBGCC_EXT} if ${MKCOMPAT} != "no". 104 # do-compat-lib-libc: builds and installs prerequisites from compat/lib/libc 105 # if ${MKCOMPAT} != "no". 106 # do-build: builds and installs the entire system. 107 # do-x11: builds and installs X11 if ${MKX11} != "no"; either 108 # X11R7 from src/external/mit/xorg if ${X11FLAVOUR} == "Xorg" 109 # or X11R6 from src/x11 110 # do-obsolete: installs the obsolete sets (for the postinstall-* targets). 111 # 112 113 .if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 114 .MAKEFLAGS: -m ${.CURDIR}/share/mk 115 .endif 116 117 # 118 # If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 119 # not be the top level objdir, because "make obj" can happen in the *middle* 120 # of "make build" (long after <bsd.own.mk> is calculated it).
