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# checkworld          - Run test suite on installed world.
25# check-old           - List obsolete directories/files/libraries.
26# check-old-dirs      - List obsolete directories.
27# check-old-files     - List obsolete files.
28# check-old-libs      - List obsolete libraries.
29# delete-old          - Delete obsolete directories/files.
30# delete-old-dirs     - Delete obsolete directories.
31# delete-old-files    - Delete obsolete files.
32# delete-old-libs     - Delete obsolete libraries.
33# targets             - Print a list of supported TARGET/TARGET_ARCH pairs
34#                       for world and kernel targets.
35# toolchains          - Build a toolchain for all world and kernel targets.
36# xdev                - xdev-build + xdev-install for the architecture
37#                       specified with TARGET and TARGET_ARCH.
38# xdev-build          - Build cross-development tools.
39# xdev-install        - Install cross-development tools.
40# xdev-links          - Create traditional links in /usr/bin for cc, etc
41# native-xtools       - Create host binaries that produce target objects
42#                       for use in qemu user-mode jails.  TARGET and
43#                       TARGET_ARCH should be defined.
44# native-xtools-install
45#                     - Install the files to the given DESTDIR/NXTP where
46#                       NXTP defaults to /nxb-bin.
47#
48# "quick" way to test all kernel builds:
49# 	_jflag=`sysctl -n hw.ncpu`
50# 	_jflag=$(($_jflag * 2))
51# 	[ $_jflag -gt 12 ] && _jflag=12
52# 	make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
53#
54# This makefile is simple by design. The FreeBSD make automatically reads
55# the /usr/share/mk/sys.mk unless the -m argument is specified on the
56# command line. By keeping this makefile simple, it doesn't matter too
57# much how different the installed mk files are from those in the source
58# tree. This makefile executes a child make process, forcing it to use
59# the mk files from the source tree which are supposed to DTRT.
60#
61# Most of the user-driven targets (as listed above) are implemented in
62# Makefile.inc1.  The exceptions are universe, tinderbox and targets.
63#
64# If you want to build your system from source be sure that /usr/obj has
65# at least 6GB of diskspace available.  A complete 'universe' build requires
66# about 100GB of space.
67#
68# For individuals wanting to build from the sources currently on their
69# system, the simple instructions are:
70#
71# 1.  `cd /usr/src'  (or to the directory containing your source tree).
72# 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
73# 3.  `make world'
74#
75# For individuals wanting to upgrade their sources (even if only a
76# delta of a few days):
77#
78#  1.  `cd /usr/src'       (or to the directory containing your source tree).
79#  2.  `make buildworld'
80#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
81#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
82#       [steps 3. & 4. can be combined by using the "kernel" target]
83#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
84#  6.  `mergemaster -p'
85#  7.  `make installworld'
86#  8.  `mergemaster'		(you may wish to use -i, along with -U or -F).
87#  9.  `make delete-old'
88# 10.  `reboot'
89# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
90#
91# See src/UPDATING `COMMON ITEMS' for more complete information.
92#
93# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can
94# cross build world for other machine types using the buildworld target,
95# and once the world is built you can cross build a kernel using the
96# buildkernel target.
97#
98# Define the user-driven targets. These are listed here in alphabetical
99# order, but that's not important.
100#
101# Targets that begin with underscore are internal targets intended for
102# developer convenience only.  They are intentionally not documented and
103# completely subject to change without notice.
104#
105# For more information, see the build(7) manual page.

109# can be cached for sub-makes. We can't do this while still running on the
110# old fmake from FreeBSD 9.x or older, so avoid including it then to avoid
111# heartburn upgrading from older systems. The need for CC is done with new
