4# The user-driven targets are:
5#
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.
28#
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.
35#
36# The user-driven targets (as listed above) are implemented in Makefile.inc1.
37#
38# If you want to build your system from source be sure that /usr/obj has
39# at least 400MB of diskspace available.
40#
41# For individuals wanting to build from the sources currently on their
42# system, the simple instructions are:
43#
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'
47#
48# For individuals wanting to upgrade their sources (even if only a
49# delta of a few days):
50#
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'
61# 10.  `reboot'
62# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
63#
64# See src/UPDATING `COMMON ITEMS' for more complete information.
65#
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.
70#
71# Define the user-driven targets. These are listed here in alphabetical
72# order, but that's not important.
73#
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.
77#
78# For more information, see the build(7) manual page.
