12# update - Convenient way to update your source tree (cvs).
13# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
14# most - Build user commands, no libraries or include files.
15# installmost - Install user commands, no libraries or include files.
16# aout-to-elf - Upgrade an system from a.out to elf format (see below).
17# aout-to-elf-build - Build everything required to upgrade a system from
18# a.out to elf format (see below).
19# aout-to-elf-install - Install everything built by aout-to-elf-build (see

22# of each elf library sub-directory.

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.inc0
32# and the private targets are in Makefile.inc1. These are kept separate
33# to help the bootstrap build from aout to elf format.
34#
35# For novices wanting to build from current sources, the simple instructions
36# are:
37#
38# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space.
39# 2. `cd /usr/src' (or to the directory containing your source tree).
40# 3. `make world'
41#
42# Be warned, this will update your installed system, except for configuration
43# files in the /etc directory and for the kernel. You have to do those manually.
44#
45# If at first you're a little nervous about having a `make world' update
46# your system, a `make buildworld' will build everything in the /usr/obj
47# tree without touching your installed system. To be of any further use
48# though, a `make installworld' is required.
49#
50# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
51# update the legacy support for aout. This includes all libraries, ld.so
52# and boot objects. This part of build should be regarded as
53# deprecated and you should _not_ expect to be able to do this past the
54# release of 4.0. You have exactly one major release to move entirely
55# to elf.

59# Upgrading an i386 system from a.out to elf format
60#
61#
62# The aout->elf transition build is performed by doing a `make upgrade' (or
63# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
64# by a `make aout-to-elf-install', depending on user preference.
65# You need to have at least 320 Mb of free space for the object tree.
66#
67# The upgrade process checks the installed release. If this is 3.0-CURRENT,
68# it is assumed that your kernel contains all the syscalls required by the
69# current sources.
70#
71# The upgrade procedure will stop and ask for confirmation to proceed
72# several times. On each occasion, you can type Ctrl-C to abort the
73# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
74# the confirmation steps.
75#
76# At the end of the upgrade procedure, /etc/objformat is created or
77# updated to contain OBJFORMAT=elf. From then on, you're elf by default.
