2 # $FreeBSD$
4 # The user-driven targets are:
6 # universe - *Really* build *everything* (buildworld and
7 # all kernels on all architectures).
8 # buildworld - Rebuild *everything*, including glue to help do
9 # upgrades.
10 # installworld - Install everything built by "buildworld".
11 # world - buildworld + installworld, no kernel.
12 # buildkernel - Rebuild the kernel and the kernel-modules.
13 # installkernel - Install the kernel and the kernel-modules.
14 # installkernel.debug
15 # reinstallkernel - Reinstall the kernel and the kernel-modules.
16 # reinstallkernel.debug
17 # kernel - buildkernel + installkernel.
18 # doxygen - Build API documentation of the kernel, needs doxygen.
19 # update - Convenient way to update your source tree (cvs).
20 # check-old - List obsolete directories/files/libraries.
21 # check-old-dirs - List obsolete directories.
22 # check-old-files - List obsolete files.
23 # check-old-libs - List obsolete libraries.
24 # delete-old - Delete obsolete directories/files/libraries.
25 # delete-old-dirs - Delete obsolete directories.
26 # delete-old-files - Delete obsolete files.
27 # delete-old-libs - Delete obsolete libraries.
29 # This makefile is simple by design. The FreeBSD make automatically reads
30 # the /usr/share/mk/sys.mk unless the -m argument is specified on the
31 # command line. By keeping this makefile simple, it doesn't matter too
32 # much how different the installed mk files are from those in the source
33 # tree. This makefile executes a child make process, forcing it to use
34 # the mk files from the source tree which are supposed to DTRT.
36 # The user-driven targets (as listed above) are implemented in Makefile.inc1.
38 # If you want to build your system from source be sure that /usr/obj has
39 # at least 800MB of diskspace available.
41 # For individuals wanting to build from the sources currently on their
42 # system, the simple instructions are:
44 # 1. `cd /usr/src' (or to the directory containing your source tree).
45 # 2. Define `HISTORICAL_MAKE_WORLD' variable (see README).
46 # 3. `make world'
48 # For individuals wanting to upgrade their sources (even if only a
49 # delta of a few days):
51 # 1. `cd /usr/src' (or to the directory containing your source tree).
52 # 2. `make buildworld'
53 # 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
54 # 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
55 # [steps 3. & 4. can be combined by using the "kernel" target]
56 # 5. `reboot' (in single user mode: boot -s from the loader prompt).
57 # 6. `mergemaster -p'
58 # 7. `make installworld'
59 # 8. `make delete-old'
60 # 9. `mergemaster' (you may wish to use -U or -ai).
61 # 10. `reboot'
62 # 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
64 # See src/UPDATING `COMMON ITEMS' for more complete information.
66 # If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
67 # cross build world for other machine types using the buildworld target,
68 # and once the world is built you can cross build a kernel using the
69 # buildkernel target.
71 # Define the user-driven targets. These are listed here in alphabetical
72 # order, but that's not important.
74 # Targets that begin with underscore are internal targets intended for
75 # developer convenience only. They are intentionally not documented and
76 # completely subject to change without notice.
78 # For more information, see the build(7) manual page.
