4# The user-driven targets are:
5#
6# universe            - *Really* build *everything* (buildworld and
7#                       all kernels on all architectures).  Define the
8#                       MAKE_JUST_KERNELS variable to only build kernels.
9# tinderbox           - Same as universe, but presents a list of failed build
10#                       targets and exits with an error if there were any.
11# buildworld          - Rebuild *everything*, including glue to help do
12#                       upgrades.
13# installworld        - Install everything built by "buildworld".
14# world               - buildworld + installworld, no kernel.
15# buildkernel         - Rebuild the kernel and the kernel-modules.
16# installkernel       - Install the kernel and the kernel-modules.
17# installkernel.debug
18# reinstallkernel     - Reinstall the kernel and the kernel-modules.
19# reinstallkernel.debug
20# kernel              - buildkernel + installkernel.
21# kernel-toolchain    - Builds the subset of world necessary to build a kernel
22# kernel-toolchains   - Build kernel-toolchain for all universe targets.
23# doxygen             - Build API documentation of the kernel, needs doxygen.
24# update              - Convenient way to update your source tree(s).
25# checkworld          - Run test suite on installed world.
26# check-old           - List obsolete directories/files/libraries.
27# check-old-dirs      - List obsolete directories.
28# check-old-files     - List obsolete files.
29# check-old-libs      - List obsolete libraries.
30# delete-old          - Delete obsolete directories/files.
31# delete-old-dirs     - Delete obsolete directories.
32# delete-old-files    - Delete obsolete files.
33# delete-old-libs     - Delete obsolete libraries.
34# targets             - Print a list of supported TARGET/TARGET_ARCH pairs
35#                       for world and kernel targets.
36# toolchains          - Build a toolchain for all world and kernel targets.
37# sysent              - (Re)build syscall entries from syscalls.master.
38# xdev                - xdev-build + xdev-install for the architecture
39#                       specified with TARGET and TARGET_ARCH.
40# xdev-build          - Build cross-development tools.
41# xdev-install        - Install cross-development tools.
42# xdev-links          - Create traditional links in /usr/bin for cc, etc
43# native-xtools       - Create host binaries that produce target objects
44#                       for use in qemu user-mode jails.  TARGET and
45#                       TARGET_ARCH should be defined.
46# native-xtools-install
47#                     - Install the files to the given DESTDIR/NXTP where
48#                       NXTP defaults to /nxb-bin.
49#
50# This makefile is simple by design. The FreeBSD make automatically reads
51# the /usr/share/mk/sys.mk unless the -m argument is specified on the
52# command line. By keeping this makefile simple, it doesn't matter too
53# much how different the installed mk files are from those in the source
54# tree. This makefile executes a child make process, forcing it to use
55# the mk files from the source tree which are supposed to DTRT.
56#
57# Most of the user-driven targets (as listed above) are implemented in
58# Makefile.inc1.  The exceptions are universe, tinderbox and targets.
59#
60# If you want to build your system from source, be sure that /usr/obj has
61# at least 6 GB of disk space available.  A complete 'universe' build of
62# r340283 (2018-11) required 167 GB of space.  ZFS lz4 compression
63# achieved a 2.18x ratio, reducing actual space to 81 GB.
64#
65# For individuals wanting to build from the sources currently on their
66# system, the simple instructions are:
67#
68# 1.  `cd /usr/src'  (or to the directory containing your source tree).
69# 2.  Define `HISTORICAL_MAKE_WORLD' variable (see README).
70# 3.  `make world'
71#
72# For individuals wanting to upgrade their sources (even if only a
73# delta of a few days):
74#
75#  1.  `cd /usr/src'       (or to the directory containing your source tree).
76#  2.  `make buildworld'
77#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
78#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
79#       [steps 3. & 4. can be combined by using the "kernel" target]
80#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
81#  6.  `mergemaster -p'
82#  7.  `make installworld'
83#  8.  `mergemaster'		(you may wish to use -i, along with -U or -F).
84#  9.  `make delete-old'
85# 10.  `reboot'
86# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
87#
88# See src/UPDATING `COMMON ITEMS' for more complete information.
89#
90# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can
91# cross build world for other machine types using the buildworld target,
92# and once the world is built you can cross build a kernel using the
93# buildkernel target.
94#
95# Define the user-driven targets. These are listed here in alphabetical
96# order, but that's not important.
97#
98# Targets that begin with underscore are internal targets intended for
99# developer convenience only.  They are intentionally not documented and
100# completely subject to change without notice.
101#
102# For more information, see the build(7) manual page.

105# This is included so CC is set to ccache for -V, and COMPILER_TYPE/VERSION
106# can be cached for sub-makes. We can't do this while still running on the
107# old fmake from FreeBSD 9.x or older, so avoid including it then to avoid
108# heartburn upgrading from older systems. The need for CC is done with new
109# make later in the build, and caching COMPILER_TYPE/VERSION is only an
110# optimization. Also sinclude it to be friendlier to foreign OS hosted builds.
