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