   4 # The user-driven targets are:
   5 #
   6 # universe            - *Really* build *everything* (buildworld and
   7 #                       all kernels on all architectures).
   8 # tinderbox           - Same as universe, but presents a list of failed build
   9 #                       targets and exits with an error if there were any.
  10 # buildworld          - Rebuild *everything*, including glue to help do
  11 #                       upgrades.
  12 # installworld        - Install everything built by "buildworld".
  13 # world               - buildworld + installworld, no kernel.
  14 # buildkernel         - Rebuild the kernel and the kernel-modules.
  15 # installkernel       - Install the kernel and the kernel-modules.
  16 # installkernel.debug
  17 # reinstallkernel     - Reinstall the kernel and the kernel-modules.
  18 # reinstallkernel.debug
  19 # kernel              - buildkernel + installkernel.
  20 # kernel-toolchain    - Builds the subset of world necessary to build a kernel
  21 # kernel-toolchains   - Build kernel-toolchain for all universe targets.
  22 # doxygen             - Build API documentation of the kernel, needs doxygen.
  23 # update              - Convenient way to update your source tree(s).
  24 # check-old           - List obsolete directories/files/libraries.
  25 # check-old-dirs      - List obsolete directories.
  26 # check-old-files     - List obsolete files.
  27 # check-old-libs      - List obsolete libraries.
  28 # delete-old          - Delete obsolete directories/files.
  29 # delete-old-dirs     - Delete obsolete directories.
  30 # delete-old-files    - Delete obsolete files.
  31 # delete-old-libs     - Delete obsolete libraries.
  32 # targets             - Print a list of supported TARGET/TARGET_ARCH pairs
  33 #                       for world and kernel targets.
  34 # toolchains          - Build a toolchain for all world and kernel targets.
  35 # xdev                - xdev-build + xdev-install for the architecture
  36 #                       specified with XDEV and XDEV_ARCH.
  37 # xdev-build          - Build cross-development tools.
  38 # xdev-install        - Install cross-development tools.
  39 # xdev-links          - Create traditional links in /usr/bin for cc, etc
  40 # native-xtools       - Create host binaries that produce target objects
  41 #                       for use in qemu user-mode jails.
  42 #
  43 # "quick" way to test all kernel builds:
  44 #       _jflag=`sysctl -n hw.ncpu`
  45 #       _jflag=$(($_jflag * 2))
  46 #       [ $_jflag -gt 12 ] && _jflag=12
  47 #       make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
  48 #
  49 # This makefile is simple by design. The FreeBSD make automatically reads
  50 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
  51 # command line. By keeping this makefile simple, it doesn't matter too
  52 # much how different the installed mk files are from those in the source
  53 # tree. This makefile executes a child make process, forcing it to use
  54 # the mk files from the source tree which are supposed to DTRT.
  55 #
  56 # Most of the user-driven targets (as listed above) are implemented in
  57 # Makefile.inc1.  The exceptions are universe, tinderbox and targets.
  58 #
  59 # If you want to build your system from source be sure that /usr/obj has
  60 # at least 6GB of diskspace available.  A complete 'universe' build requires
  61 # about 100GB of space.
  62 #
  63 # For individuals wanting to build from the sources currently on their
  64 # system, the simple instructions are:
  65 #
  66 # 1.  `cd /usr/src'  (or to the directory containing your source tree).
  67 # 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
  68 # 3.  `make world'
  69 #
  70 # For individuals wanting to upgrade their sources (even if only a
  71 # delta of a few days):
  72 #
  73 #  1.  `cd /usr/src'       (or to the directory containing your source tree).
  74 #  2.  `make buildworld'
  75 #  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
  76 #  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
  77 #       [steps 3. & 4. can be combined by using the "kernel" target]
  78 #  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
  79 #  6.  `mergemaster -p'
  80 #  7.  `make installworld'
  81 #  8.  `mergemaster'            (you may wish to use -i, along with -U or -F).
  82 #  9.  `make delete-old'
  83 # 10.  `reboot'
  84 # 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
  85 #
  86 # See src/UPDATING `COMMON ITEMS' for more complete information.
  87 #
  88 # If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can
  89 # cross build world for other machine types using the buildworld target,
  90 # and once the world is built you can cross build a kernel using the
  91 # buildkernel target.
