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.
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           - Print a list of old files/directories in the system.
21# delete-old          - Delete obsolete files and directories interactively.
22# delete-old-libs     - Delete obsolete libraries interactively.
23#
24# This makefile is simple by design. The FreeBSD make automatically reads
25# the /usr/share/mk/sys.mk unless the -m argument is specified on the
26# command line. By keeping this makefile simple, it doesn't matter too
27# much how different the installed mk files are from those in the source
28# tree. This makefile executes a child make process, forcing it to use
29# the mk files from the source tree which are supposed to DTRT.
30#
31# The user-driven targets (as listed above) are implemented in Makefile.inc1.
32#
33# If you want to build your system from source be sure that /usr/obj has
34# at least 400MB of diskspace available.
35#
36# For individuals wanting to build from the sources currently on their
37# system, the simple instructions are:
38#
39# 1.  `cd /usr/src'  (or to the directory containing your source tree).
40# 2.  `make world'
41#
42# For individuals wanting to upgrade their sources (even if only a
43# delta of a few days):
44#
45#  1.  `cd /usr/src'       (or to the directory containing your source tree).
46#  2.  `make buildworld'
47#  3.  `make buildkernel KERNCONF=YOUR_KERNEL_HERE'     (default is GENERIC).
48#  4.  `make installkernel KERNCONF=YOUR_KERNEL_HERE'   (default is GENERIC).
49#  5.  `reboot'        (in single user mode: boot -s from the loader prompt).
50#  6.  `mergemaster -p'
51#  7.  `make installworld'
52#  8.  `make delete-old'
53#  9.  `mergemaster'
54# 10.  `reboot'
55# 11.  `make delete-old-libs' (in case no 3rd party program uses them anymore)
56#
57# See src/UPDATING `COMMON ITEMS' for more complete information.
58#
59# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
60# cross build world for other architectures using the buildworld target,
61# and once the world is built you can cross build a kernel using the
62# buildkernel target.
63#
64# Define the user-driven targets. These are listed here in alphabetical
65# order, but that's not important.
66#
67# Targets that begin with underscore are internal targets intended for
68# developer convenience only.  They are intentionally not documented and
69# completely subject to change without notice.
