5# The user-driven targets are:
6#
7# buildworld - Rebuild *everything*, including glue to help do
8# upgrades.
9# installworld - Install everything built by "buildworld".
10# world - buildworld + installworld.
11# buildkernel - Rebuild the kernel and the kernel-modules.
12# installkernel - Install the kernel and the kernel-modules.
13# reinstallkernel - Reinstall the kernel and the kernel-modules.
14# kernel - buildkernel + installkernel.
15# update - Convenient way to update your source tree (cvs).
16# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
17# most - Build user commands, no libraries or include files.
18# installmost - Install user commands, no libraries or include files.
19# aout-to-elf - Upgrade an system from a.out to elf format (see below).
20# aout-to-elf-build - Build everything required to upgrade a system from
21# a.out to elf format (see below).
22# aout-to-elf-install - Install everything built by aout-to-elf-build (see
23# below).
24# move-aout-libs - Move the a.out libraries into an aout sub-directory
25# of each elf library sub-directory.
26#
27# This makefile is simple by design. The FreeBSD make automatically reads
28# the /usr/share/mk/sys.mk unless the -m argument is specified on the
29# command line. By keeping this makefile simple, it doesn't matter too
30# much how different the installed mk files are from those in the source
31# tree. This makefile executes a child make process, forcing it to use
32# the mk files from the source tree which are supposed to DTRT.
33#
34# The user-driven targets (as listed above) are implemented in Makefile.inc1.
35#
36# If you want to build your system from source be sure that /usr/obj has
37# at least 400MB of diskspace available.
38#
39# For individuals wanting to build from the sources currently on their
40# system, the simple instructions are:
41#
42# 1. `cd /usr/src' (or to the directory containing your source tree).
43# 2. `make world'
44#
45# For individuals wanting to upgrade their sources (even if only a
46# delta of a few days):
47#
48# 1. `cd /usr/src' (or to the directory containing your source tree).
49# 2. `make buildworld'
50# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
51# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
52# 5. `reboot' (in single user mode: boot -s from the loader prompt).
53# 6. `mergemaster -p'
54# 7. `make installworld'
55# 8. `mergemaster'
56# 9. `reboot'
57#
58# See src/UPDATING `COMMON ITEMS' for more complete information.
59#
60# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
61# update the legacy support for aout. This includes all libraries, ld.so
62# and boot objects. This part of build should be regarded as
63# deprecated and you should _not_ expect to be able to do this past the
64# release of 4.0. You have exactly one major release to move entirely
65# to elf.
66#
67# If TARGET_ARCH=arch (e.g. alpha) is specified you can
68# cross build world for other architectures using the buildworld target,
69# and once the world is built you can cross build a kernel using the
70# buildkernel target.

74# Upgrading an i386 system from a.out to elf format
75#
76#
77# The aout->elf transition build is performed by doing a `make upgrade' (or
78# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
79# by a `make aout-to-elf-install', depending on user preference.
80# You need to have at least 320 Mb of free space for the object tree.
81#
82# The upgrade process checks the installed release. If this is 3.0-CURRENT,
83# it is assumed that your kernel contains all the syscalls required by the
84# current sources.
85#
86# The upgrade procedure will stop and ask for confirmation to proceed
87# several times. On each occasion, you can type Ctrl-C to abort the
88# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
89# the confirmation steps.
90#
91# At the end of the upgrade procedure, /etc/objformat is created or
92# updated to contain OBJFORMAT=elf. From then on, you're elf by default.
