Makefile revision 1.331
1 # $NetBSD: Makefile,v 1.331 2019/08/27 22:48:54 kamil 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 # NOBINARIES will not build binaries, only includes and libraries 34 # 35 # See mk.conf(5) for more details. 36 # 37 # 38 # Targets: 39 # build: 40 # Builds a full release of NetBSD in DESTDIR, except for the 41 # /etc configuration files. 42 # If BUILD_DONE is set, this is an empty target. 43 # distribution: 44 # Builds a full release of NetBSD in DESTDIR, including the /etc 45 # configuration files. 46 # buildworld: 47 # As per `make distribution', except that it ensures that DESTDIR 48 # is not the root directory. 49 # installworld: 50 # Install the distribution from DESTDIR to INSTALLWORLDDIR (which 51 # defaults to the root directory). Ensures that INSTALLWORLDDIR 52 # is not the root directory if cross compiling. 53 # release: 54 # Does a `make distribution', and then tars up the DESTDIR files 55 # into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format. 56 # (See etc/Makefile for more information on this.) 57 # regression-tests: 58 # Runs the regression tests in "regress" on this host. 59 # sets: 60 # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets 61 # from ${DESTDIR} 62 # sourcesets: 63 # Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR} 64 # syspkgs: 65 # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs 66 # from ${DESTDIR} 67 # iso-image: 68 # Create CD-ROM image in RELEASEDIR/images. 69 # RELEASEDIR must already have been populated by `make release' 70 # or equivalent. 71 # iso-image-source: 72 # Create CD-ROM image with source in RELEASEDIR/images. 73 # RELEASEDIR must already have been populated by 74 # `make release sourcesets' or equivalent. 75 # live-image: 76 # Create bootable live image for emulators or USB stick etc. 77 # in RELEASEDIR/liveimage. 78 # RELEASEDIR must already have been populated by `make release' 79 # or equivalent. 80 # install-image: 81 # Create bootable installation image for USB stick etc. 82 # in RELEASEDIR/installimage. 83 # RELEASEDIR must already have been populated by `make release' 84 # or equivalent. 85 # 86 # Targets invoked by `make build,' in order: 87 # cleandir: cleans the tree. 88 # do-top-obj: creates the top level object directory. 89 # do-tools-obj: creates object directories for the host toolchain. 90 # do-tools: builds host toolchain. 91 # params: record the values of variables that might affect the 92 # build. 93 # obj: creates object directories. 94 # do-distrib-dirs: creates the distribution directories. 95 # includes: installs include files. 96 # do-lib: builds and installs prerequisites from lib. 97 # do-compat-lib: builds and installs prerequisites from compat/lib 98 # if ${MKCOMPAT} != "no". 99 # do-x11: builds and installs X11 tools and libraries 100 # from src/external/mit/xorg if ${MKX11} != "no". 101 # do-build: builds and installs the entire system. 102 # do-extsrc: builds and installs extsrc if ${MKEXTSRC} != "no". 103 # do-obsolete: installs the obsolete sets (for the postinstall-* targets). 104 # 105 106 .if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" 107 .MAKEFLAGS: -m ${.CURDIR}/share/mk 108 .endif 109 110 # 111 # If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may 112 # not be the top level objdir, because "make obj" can happen in the *middle* 113 # of "make build" (long after <bsd.own.mk> is calculated it).
