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 1GB of diskspace available.  A complete 'universe' build requires
61# about 15GB 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.
92#
93# Define the user-driven targets. These are listed here in alphabetical
94# order, but that's not important.
95#
96# Targets that begin with underscore are internal targets intended for
97# developer convenience only.  They are intentionally not documented and
98# completely subject to change without notice.
99#
100# For more information, see the build(7) manual page.
