    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/${MACHINE}, 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 ${RELEASEDIR}/${MACHINE}/binary/sets from ${DESTDIR}
   60: #   sourcesets:
   61: #       Populate ${RELEASEDIR}/source/sets from ${NETBSDSRCDIR}
   62: #   syspkgs:
   63: #       Populate ${RELEASEDIR}/${MACHINE}/binary/syspkgs from ${DESTDIR}
   64: #   iso-image:
   65: #       Create CD-ROM image in RELEASEDIR/iso.
   66: #       RELEASEDIR must already have been populated by `make release'
   67: #       or equivalent.
   68: #   iso-image-source:
   69: #       Create CD-ROM image with source in RELEASEDIR/iso.
   70: #       RELEASEDIR must already have been populated by
   71: #       `make release sourcesets' or equivalent.
   72: #

   74: #   cleandir:        cleans the tree.
   75: #   obj:             creates object directories.

   78: #   includes:        installs include files.
