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 or WITHOUT_WORLDS to only build kernels,
9#                       MAKE_JUST_WORLDS or WITHOUT_KERNELS 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# worlds	      - Same as universe, except just makes the worlds.
13# kernels	      - Same as universe, except just makes the kernels.
14# buildworld          - Rebuild *everything*, including glue to help do
15#                       upgrades.
16# installworld        - Install everything built by "buildworld".
17# world               - buildworld + installworld, no kernel.
18# buildkernel         - Rebuild the kernel and the kernel-modules.
19# installkernel       - Install the kernel and the kernel-modules.
20# installkernel.debug
21# reinstallkernel     - Reinstall the kernel and the kernel-modules.
22# reinstallkernel.debug
23# kernel              - buildkernel + installkernel.
24# kernel-toolchain    - Builds the subset of world necessary to build a kernel
25# kernel-toolchains   - Build kernel-toolchain for all universe targets.
26# doxygen             - Build API documentation of the kernel, needs doxygen.
27# update              - Convenient way to update your source tree(s).
28# checkworld          - Run test suite on installed world.
29# check-old           - List obsolete directories/files/libraries.
30# check-old-dirs      - List obsolete directories.
31# check-old-files     - List obsolete files.
32# check-old-libs      - List obsolete libraries.
33# delete-old          - Delete obsolete directories/files.
34# delete-old-dirs     - Delete obsolete directories.
35# delete-old-files    - Delete obsolete files.
36# delete-old-libs     - Delete obsolete libraries.
37# targets             - Print a list of supported TARGET/TARGET_ARCH pairs
38#                       for world and kernel targets.
39# toolchains          - Build a toolchain for all world and kernel targets.
40# makeman             - Regenerate src.conf(5)
41# sysent              - (Re)build syscall entries from syscalls.master.
42# xdev                - xdev-build + xdev-install for the architecture
43#                       specified with TARGET and TARGET_ARCH.
44# xdev-build          - Build cross-development tools.
45# xdev-install        - Install cross-development tools.
46# xdev-links          - Create traditional links in /usr/bin for cc, etc
47# native-xtools       - Create host binaries that produce target objects
48#                       for use in qemu user-mode jails.  TARGET and
49#                       TARGET_ARCH should be defined.
50# native-xtools-install
51#                     - Install the files to the given DESTDIR/NXTP where
52#                       NXTP defaults to /nxb-bin.
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 6 GB of disk space available.  A complete 'universe' build of
66# r340283 (2018-11) required 167 GB of space.  ZFS lz4 compression
67# achieved a 2.18x ratio, reducing actual space to 81 GB.
68#
69# For individuals wanting to build from the sources currently on their
70# system, the simple instructions are:
71#
72# 1.  `cd /usr/src'  (or to the directory containing your source tree).
73# 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
74# 3.  `make world'
75#
76# For individuals wanting to upgrade their sources (even if only a
77# delta of a few days):
78#
79#  1.  `cd /usr/src'       (or to the directory containing your source tree).
80#  2.  `make buildworld'
81#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
82#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
83#       [steps 3. & 4. can be combined by using the "kernel" target]
84#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
85#  6.  `mergemaster -p'
86#  7.  `make installworld'
87#  8.  `mergemaster'            (you may wish to use -i, along with -U or -F).
88#  9.  `make delete-old'
89# 10.  `reboot'
90# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
91#
92# For individuals wanting to build from source with GCC from ports, first build
93# or install an appropriate flavor of devel/freebsd-gcc9.  The packages produced
94# by this port are named "${TARGET_ARCH}-gcc9" -- note that not all
95# architectures supported by FreeBSD have an external gcc toolchain available.
96#
97# Once the appropriate freebsd-gcc package is installed, simply pass
98# CROSS_TOOLCHAIN=${TARGET_ARCH}-gcc9 while building with the above steps,
99# e.g., `make buildworld CROSS_TOOLCHAIN=amd64-gcc9`.
100#
101# See src/UPDATING `COMMON ITEMS' for more complete information.
102#
103# If TARGET=machine (e.g. powerpc, arm64, ...) is specified you can
104# cross build world for other machine types using the buildworld target,
105# and once the world is built you can cross build a kernel using the
106# buildkernel target.
107#
108# Define the user-driven targets. These are listed here in alphabetical
109# order, but that's not important.
110#
111# Targets that begin with underscore are internal targets intended for
112# developer convenience only.  They are intentionally not documented and
113# completely subject to change without notice.
114#
115# For more information, see the build(7) manual page.
