      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 not the 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 #   live-image:
     75 #	Create bootable live image for emulators or USB stick etc.
     76 #	in RELEASEDIR/liveimage.
     77 #	RELEASEDIR must already have been populated by `make release'
     78 #	or equivalent.
     79 #   install-image:
     80 #	Create bootable installation image for USB stick etc.
     81 #	in RELEASEDIR/installimage.
     82 #	RELEASEDIR must already have been populated by `make release'
     83 #	or equivalent.
     84 #
     85 # Targets invoked by `make build,' in order:
     86 #   cleandir:        cleans the tree.
     87 #   do-top-obj:      creates the top level object directory.
     88 #   do-tools-obj:    creates object directories for the host toolchain.
     89 #   do-tools:        builds host toolchain.
     90 #   params:          record the values of variables that might affect the
     91 #                    build.
     92 #   obj:             creates object directories.
     93 #   do-distrib-dirs: creates the distribution directories.
     94 #   includes:        installs include files.
