4# The user-driven targets are:
5#
6# universe            - *Really* build *everything* (buildworld and
7#                       all kernels on all architectures).  Define
8#                       MAKE_JUST_KERNELS to only build kernels,
9#                       MAKE_JUST_WORLDS to only build userland.
10# tinderbox           - Same as universe, but presents a list of failed build
11#                       targets and exits with an error if there were any.
12# buildworld          - Rebuild *everything*, including glue to help do
13#                       upgrades.
14# installworld        - Install everything built by "buildworld".
15# world               - buildworld + installworld, no kernel.
16# buildkernel         - Rebuild the kernel and the kernel-modules.
17# installkernel       - Install the kernel and the kernel-modules.
18# installkernel.debug
19# reinstallkernel     - Reinstall the kernel and the kernel-modules.
20# reinstallkernel.debug
21# kernel              - buildkernel + installkernel.
22# kernel-toolchain    - Builds the subset of world necessary to build a kernel
23# kernel-toolchains   - Build kernel-toolchain for all universe targets.
24# doxygen             - Build API documentation of the kernel, needs doxygen.
25# update              - Convenient way to update your source tree(s).
26# checkworld          - Run test suite on installed world.
27# check-old           - List obsolete directories/files/libraries.
28# check-old-dirs      - List obsolete directories.
29# check-old-files     - List obsolete files.
30# check-old-libs      - List obsolete libraries.
31# delete-old          - Delete obsolete directories/files.
32# delete-old-dirs     - Delete obsolete directories.
33# delete-old-files    - Delete obsolete files.
34# delete-old-libs     - Delete obsolete libraries.
35# targets             - Print a list of supported TARGET/TARGET_ARCH pairs
36#                       for world and kernel targets.
37# toolchains          - Build a toolchain for all world and kernel targets.
38# makeman             - Regenerate src.conf(5)
39# sysent              - (Re)build syscall entries from syscalls.master.
40# xdev                - xdev-build + xdev-install for the architecture
41#                       specified with TARGET and TARGET_ARCH.
42# xdev-build          - Build cross-development tools.
43# xdev-install        - Install cross-development tools.
44# xdev-links          - Create traditional links in /usr/bin for cc, etc
45# native-xtools       - Create host binaries that produce target objects
46#                       for use in qemu user-mode jails.  TARGET and
47#                       TARGET_ARCH should be defined.
48# native-xtools-install
49#                     - Install the files to the given DESTDIR/NXTP where
50#                       NXTP defaults to /nxb-bin.
51#
52# This makefile is simple by design. The FreeBSD make automatically reads
53# the /usr/share/mk/sys.mk unless the -m argument is specified on the
54# command line. By keeping this makefile simple, it doesn't matter too
55# much how different the installed mk files are from those in the source
56# tree. This makefile executes a child make process, forcing it to use
57# the mk files from the source tree which are supposed to DTRT.
58#
59# Most of the user-driven targets (as listed above) are implemented in
60# Makefile.inc1.  The exceptions are universe, tinderbox and targets.
61#
62# If you want to build your system from source, be sure that /usr/obj has
63# at least 6 GB of disk space available.  A complete 'universe' build of
64# r340283 (2018-11) required 167 GB of space.  ZFS lz4 compression
65# achieved a 2.18x ratio, reducing actual space to 81 GB.
66#
67# For individuals wanting to build from the sources currently on their
68# system, the simple instructions are:
69#
70# 1.  `cd /usr/src'  (or to the directory containing your source tree).
71# 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
72# 3.  `make world'
73#
74# For individuals wanting to upgrade their sources (even if only a
75# delta of a few days):
76#
77#  1.  `cd /usr/src'       (or to the directory containing your source tree).
78#  2.  `make buildworld'
79#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
80#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
81#       [steps 3. & 4. can be combined by using the "kernel" target]
82#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
83#  6.  `mergemaster -p'
84#  7.  `make installworld'
85#  8.  `mergemaster'            (you may wish to use -i, along with -U or -F).
86#  9.  `make delete-old'
87# 10.  `reboot'
88# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
89#
90# See src/UPDATING `COMMON ITEMS' for more complete information.
91#
92# If TARGET=machine (e.g. powerpc, arm64, ...) is specified you can
93# cross build world for other machine types using the buildworld target,
94# and once the world is built you can cross build a kernel using the
95# buildkernel target.
96#
97# Define the user-driven targets. These are listed here in alphabetical
98# order, but that's not important.
99#
100# Targets that begin with underscore are internal targets intended for
101# developer convenience only.  They are intentionally not documented and
102# completely subject to change without notice.
103#
104# For more information, see the build(7) manual page.

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