   4 # The user-driven targets are:
   5 #
   6 # universe            - *Really* build *everything* (buildworld and
   7 #                       all kernels on all architectures).
   8 # buildworld          - Rebuild *everything*, including glue to help do
   9 #                       upgrades.
  10 # installworld        - Install everything built by "buildworld".
  11 # world               - buildworld + installworld, no kernel.
  12 # buildkernel         - Rebuild the kernel and the kernel-modules.
  13 # installkernel       - Install the kernel and the kernel-modules.
  14 # installkernel.debug
  15 # reinstallkernel     - Reinstall the kernel and the kernel-modules.
  16 # reinstallkernel.debug
  17 # kernel              - buildkernel + installkernel.
  18 # doxygen             - Build API documentation of the kernel, needs doxygen.
  19 # update              - Convenient way to update your source tree (cvs).
  20 # check-old           - List obsolete directories/files/libraries.
  21 # check-old-dirs      - List obsolete directories.
  22 # check-old-files     - List obsolete files.
  23 # check-old-libs      - List obsolete libraries.
  24 # delete-old          - Delete obsolete directories/files/libraries.
  25 # delete-old-dirs     - Delete obsolete directories.
  26 # delete-old-files    - Delete obsolete files.
  27 # delete-old-libs     - Delete obsolete libraries.

  29 # This makefile is simple by design. The FreeBSD make automatically reads
  30 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
  31 # command line. By keeping this makefile simple, it doesn't matter too
  32 # much how different the installed mk files are from those in the source
  33 # tree. This makefile executes a child make process, forcing it to use
  34 # the mk files from the source tree which are supposed to DTRT.
  35 #
  36 # The user-driven targets (as listed above) are implemented in Makefile.inc1.
  37 #
  38 # If you want to build your system from source be sure that /usr/obj has
  39 # at least 800MB of diskspace available.
  40 #
  41 # For individuals wanting to build from the sources currently on their
  42 # system, the simple instructions are:
  43 #
  44 # 1.  `cd /usr/src'  (or to the directory containing your source tree).
  45 # 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
  46 # 3.  `make world'
  47 #
  48 # For individuals wanting to upgrade their sources (even if only a
  49 # delta of a few days):
  50 #
  51 #  1.  `cd /usr/src'       (or to the directory containing your source tree).
  52 #  2.  `make buildworld'
  53 #  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
  54 #  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
  55 #       [steps 3. & 4. can be combined by using the "kernel" target]
  56 #  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
  57 #  6.  `mergemaster -p'
  58 #  7.  `make installworld'
  59 #  8.  `make delete-old'
  60 #  9.  `mergemaster'                         (you may wish to use -U or -ai).
  61 # 10.  `reboot'
  62 # 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
  63 #
  64 # See src/UPDATING `COMMON ITEMS' for more complete information.
  65 #
  66 # If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
  67 # cross build world for other machine types using the buildworld target,
  68 # and once the world is built you can cross build a kernel using the
  69 # buildkernel target.
  70 #
  71 # Define the user-driven targets. These are listed here in alphabetical
  72 # order, but that's not important.
  73 #
  74 # Targets that begin with underscore are internal targets intended for
  75 # developer convenience only.  They are intentionally not documented and
  76 # completely subject to change without notice.
  77 #
  78 # For more information, see the build(7) manual page.
