4 # The user-driven targets are:
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
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.
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 XDEV and XDEV_ARCH.
38 # xdev-build - Build cross-development tools.
39 # xdev-install - Install cross-development tools.
40 # native-xtools - Create host binaries that produce target objects
41 # for use in qemu user-mode jails.
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}
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.
56 # Most of the user-driven targets (as listed above) are implemented in
57 # Makefile.inc1. The exceptions are universe, tinderbox and targets.
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.
63 # For individuals wanting to build from the sources currently on their
64 # system, the simple instructions are:
66 # 1. `cd /usr/src' (or to the directory containing your source tree).
67 # 2. Define `HISTORICAL_MAKE_WORLD' variable (see README).
70 # For individuals wanting to upgrade their sources (even if only a
71 # delta of a few days):
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).
80 # 7. `make installworld'
81 # 8. `mergemaster' (you may wish to use -i, along with -U or -F).
82 # 9. `make delete-old'
84 # 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
86 # See src/UPDATING `COMMON ITEMS' for more complete information.
88 # If TARGET=machine (e.g. ia64, 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
93 # Define the user-driven targets. These are listed here in alphabetical
94 # order, but that's not important.
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.
100 # For more information, see the build(7) manual page.
