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

62#
63# For individuals wanting to upgrade their sources (even if only a
64# delta of a few days):
65#
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).
72# 6. `mergemaster -p'
73# 7. `make installworld'
74# 8. `mergemaster' (you may wish to use -i, along with -U or -F).
75# 9. `make delete-old'
76# 10. `reboot'
77# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
78#
79# See src/UPDATING `COMMON ITEMS' for more complete information.
80#
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
84# buildkernel target.
85#
86# Define the user-driven targets. These are listed here in alphabetical
87# order, but that's not important.
88#
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.
