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 # check-old - List obsolete directories/files/libraries.
25 # check-old-dirs - List obsolete directories.
26 # check-old-files - List obsolete files.
27 # check-old-libs - List obsolete libraries.
28 # delete-old - Delete obsolete directories/files.
29 # delete-old-dirs - Delete obsolete directories.
30 # delete-old-files - Delete obsolete files.
31 # delete-old-libs - Delete obsolete libraries.
32 # targets - Print a list of supported TARGET/TARGET_ARCH pairs
33 # for world and kernel targets.
34 # toolchains - Build a toolchain for all world and kernel targets.
36 # "quick" way to test all kernel builds:
37 # _jflag=`sysctl -n hw.ncpu`
38 # _jflag=$(($_jflag * 2))
39 # [ $_jflag -gt 12 ] && _jflag=12
40 # make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
42 # This makefile is simple by design. The FreeBSD make automatically reads
43 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
44 # command line. By keeping this makefile simple, it doesn't matter too
45 # much how different the installed mk files are from those in the source
46 # tree. This makefile executes a child make process, forcing it to use
47 # the mk files from the source tree which are supposed to DTRT.
49 # Most of the user-driven targets (as listed above) are implemented in
50 # Makefile.inc1. The exceptions are universe, tinderbox and targets.
52 # If you want to build your system from source be sure that /usr/obj has
53 # at least 1GB of diskspace available. A complete 'universe' build requires
54 # about 15GB of space.
56 # For individuals wanting to build from the sources currently on their
57 # system, the simple instructions are:
59 # 1. `cd /usr/src' (or to the directory containing your source tree).
60 # 2. Define `HISTORICAL_MAKE_WORLD' variable (see README).
63 # For individuals wanting to upgrade their sources (even if only a
64 # delta of a few days):
66 # 1. `cd /usr/src' (or to the directory containing your source tree).
67 # 2. `make buildworld'
68 # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
69 # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
70 # [steps 3. & 4. can be combined by using the "kernel" target]
71 # 5. `reboot' (in single user mode: boot -s from the loader prompt).
73 # 7. `make installworld'
74 # 8. `mergemaster' (you may wish to use -i, along with -U or -F).
75 # 9. `make delete-old'
77 # 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
79 # See src/UPDATING `COMMON ITEMS' for more complete information.
81 # If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
82 # cross build world for other machine types using the buildworld target,
83 # and once the world is built you can cross build a kernel using the
86 # Define the user-driven targets. These are listed here in alphabetical
87 # order, but that's not important.
89 # Targets that begin with underscore are internal targets intended for
90 # developer convenience only. They are intentionally not documented and
91 # completely subject to change without notice.
93 # For more information, see the build(7) manual page.
