   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.

  79 #   do-tools:        builds host toolchain.
  80 #   obj:             creates object directories.

  88 #                    gnu/lib/libgcc${LIBGCC_EXT}.
  89 #   do-libpcc:       builds and install prerequisites from
