# $NetBSD: Makefile,v 1.327.2.1 2019/09/01 10:36:26 martin Exp $ # # This is the top-level makefile for building NetBSD. For an outline of # how to build a snapshot or release, as well as other release engineering # information, see http://www.NetBSD.org/developers/releng/index.html # # Not everything you can set or do is documented in this makefile. In # particular, you should review the files in /usr/share/mk (especially # bsd.README) for general information on building programs and writing # Makefiles within this structure, and see the comments in src/etc/Makefile # for further information on installation and release set options. # # Variables listed below can be set on the make command line (highest # priority), in /etc/mk.conf (middle priority), or in the environment # (lowest priority). # # Variables: # DESTDIR is the target directory for installation of the compiled # software. It defaults to /. Note that programs are built against # libraries installed in DESTDIR. # MKMAN, if `no', will prevent building of manual pages. # MKOBJDIRS, if not `no', will build object directories at # an appropriate point in a build. # MKSHARE, if `no', will prevent building and installing # anything in /usr/share. # MKUPDATE, if not `no', will avoid a `make cleandir' at the start of # `make build', as well as having the effects listed in # /usr/share/mk/bsd.README. # NOCLEANDIR, if defined, will avoid a `make cleandir' at the start # of the `make build'. # NOINCLUDES will avoid the `make includes' usually done by `make build'. # NOBINARIES will not build binaries, only includes and libraries # # See mk.conf(5) for more details. # # # Targets: # build: # Builds a full release of NetBSD in DESTDIR, except for the # /etc configuration files. # If BUILD_DONE is set, this is an empty target. # distribution: # Builds a full release of NetBSD in DESTDIR, including the /etc # configuration files. # buildworld: # As per `make distribution', except that it ensures that DESTDIR # is not the root directory. # installworld: # Install the distribution from DESTDIR to INSTALLWORLDDIR (which # defaults to the root directory). Ensures that INSTALLWORLDDIR # is not the root directory if cross compiling. # release: # Does a `make distribution', and then tars up the DESTDIR files # into ${RELEASEDIR}/${RELEASEMACHINEDIR}, in release(7) format. # (See etc/Makefile for more information on this.) # regression-tests: # Runs the regression tests in "regress" on this host. # sets: # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/sets # from ${DESTDIR} # sourcesets: # Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR} # syspkgs: # Populate ${RELEASEDIR}/${RELEASEMACHINEDIR}/binary/syspkgs # from ${DESTDIR} # iso-image: # Create CD-ROM image in RELEASEDIR/images. # RELEASEDIR must already have been populated by `make release' # or equivalent. # iso-image-source: # Create CD-ROM image with source in RELEASEDIR/images. # RELEASEDIR must already have been populated by # `make release sourcesets' or equivalent. # live-image: # Create bootable live image for emulators or USB stick etc. # in RELEASEDIR/liveimage. # RELEASEDIR must already have been populated by `make release' # or equivalent. # install-image: # Create bootable installation image for USB stick etc. # in RELEASEDIR/installimage. # RELEASEDIR must already have been populated by `make release' # or equivalent. # # Targets invoked by `make build,' in order: # cleandir: cleans the tree. # do-top-obj: creates the top level object directory. # do-tools-obj: creates object directories for the host toolchain. # do-tools: builds host toolchain. # params: record the values of variables that might affect the # build. # obj: creates object directories. # do-distrib-dirs: creates the distribution directories. # includes: installs include files. # do-lib: builds and installs prerequisites from lib. # do-compat-lib: builds and installs prerequisites from compat/lib # if ${MKCOMPAT} != "no". # do-x11: builds and installs X11 tools and libraries # from src/external/mit/xorg if ${MKX11} != "no". # do-build: builds and installs the entire system. # do-extsrc: builds and installs extsrc if ${MKEXTSRC} != "no". # do-obsolete: installs the obsolete sets (for the postinstall-* targets). # .if ${.MAKEFLAGS:M${.CURDIR}/share/mk} == "" .MAKEFLAGS: -m ${.CURDIR}/share/mk .endif # # If _SRC_TOP_OBJ_ gets set here, we will end up with a directory that may # not be the top level objdir, because "make obj" can happen in the *middle* # of "make build" (long after is calculated it).
