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# doxygen             - Build API documentation of the kernel, needs doxygen.
22# update              - Convenient way to update your source tree(s).
23# check-old           - List obsolete directories/files/libraries.
24# check-old-dirs      - List obsolete directories.
25# check-old-files     - List obsolete files.
26# check-old-libs      - List obsolete libraries.
27# delete-old          - Delete obsolete directories/files.
28# delete-old-dirs     - Delete obsolete directories.
29# delete-old-files    - Delete obsolete files.
30# delete-old-libs     - Delete obsolete libraries.
31# targets             - Print a list of supported TARGET/TARGET_ARCH pairs
32#                       for world and kernel targets.
33# toolchains          - Build a toolchain for all world and kernel targets.
34# xdev                - xdev-build + xdev-install for the architecture
35#                       specified with XDEV and XDEV_ARCH.
36# xdev-build          - Build cross-development tools.
37# xdev-install        - Install cross-development tools.
38#
39# This makefile is simple by design. The FreeBSD make automatically reads
40# the /usr/share/mk/sys.mk unless the -m argument is specified on the
41# command line. By keeping this makefile simple, it doesn't matter too
42# much how different the installed mk files are from those in the source
43# tree. This makefile executes a child make process, forcing it to use
44# the mk files from the source tree which are supposed to DTRT.
45#
46# Most of the user-driven targets (as listed above) are implemented in
47# Makefile.inc1.  The exceptions are universe, tinderbox and targets.
48#
49# If you want to build your system from source be sure that /usr/obj has
50# at least 1GB of diskspace available.  A complete 'universe' build requires
51# about 15GB of space.
52#
53# For individuals wanting to build from the sources currently on their
54# system, the simple instructions are:
55#
56# 1.  `cd /usr/src'  (or to the directory containing your source tree).
57# 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
58# 3.  `make world'
59#
60# For individuals wanting to upgrade their sources (even if only a
61# delta of a few days):
62#
63#  1.  `cd /usr/src'       (or to the directory containing your source tree).
64#  2.  `make buildworld'
65#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
66#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
67#       [steps 3. & 4. can be combined by using the "kernel" target]
68#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
69#  6.  `mergemaster -p'
70#  7.  `make installworld'
71#  8.  `make delete-old'
72#  9.  `mergemaster'		(you may wish to use -i, along with -U or -F).
73# 10.  `reboot'
74# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
75#
76# See src/UPDATING `COMMON ITEMS' for more complete information.
77#
78# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
79# cross build world for other machine types using the buildworld target,
80# and once the world is built you can cross build a kernel using the
81# buildkernel target.
82#
83# Define the user-driven targets. These are listed here in alphabetical
84# order, but that's not important.
85#
86# Targets that begin with underscore are internal targets intended for
87# developer convenience only.  They are intentionally not documented and
88# completely subject to change without notice.
89#
90# For more information, see the build(7) manual page.
