1# 2# $FreeBSD$ 3# 4# The user-driven targets are: 5# 6# buildworld - Rebuild *everything*, including glue to help do 7# upgrades. 8# installworld - Install everything built by "buildworld". 9# world - buildworld + installworld. 10# buildkernel - Rebuild the kernel and the kernel-modules. 11# installkernel - Install the kernel and the kernel-modules. 12# reinstallkernel - Reinstall the kernel and the kernel-modules. 13# update - Convenient way to update your source tree (cvs). 14# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 15# most - Build user commands, no libraries or include files. 16# installmost - Install user commands, no libraries or include files. 17# aout-to-elf - Upgrade an system from a.out to elf format (see below). 18# aout-to-elf-build - Build everything required to upgrade a system from 19# a.out to elf format (see below). 20# aout-to-elf-install - Install everything built by aout-to-elf-build (see 21# below). 22# move-aout-libs - Move the a.out libraries into an aout sub-directory 23# of each elf library sub-directory. 24# 25# This makefile is simple by design. The FreeBSD make automatically reads 26# the /usr/share/mk/sys.mk unless the -m argument is specified on the 27# command line. By keeping this makefile simple, it doesn't matter too 28# much how different the installed mk files are from those in the source 29# tree. This makefile executes a child make process, forcing it to use 30# the mk files from the source tree which are supposed to DTRT. 31# 32# The user-driven targets (as listed above) are implemented in Makefile.inc0 33# and the private targets are in Makefile.inc1. These are kept separate 34# to help the bootstrap build from aout to elf format. 35# 36# For novices wanting to build from current sources, the simple instructions 37# are: 38# 39# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 40# 2. `cd /usr/src' (or to the directory containing your source tree). 41# 3. `make world' 42# 43# Be warned, this will update your installed system, except for configuration 44# files in the /etc directory and for the kernel. You have to do those manually. 45# 46# If at first you're a little nervous about having a `make world' update 47# your system, a `make buildworld' will build everything in the /usr/obj 48# tree without touching your installed system. To be of any further use 49# though, a `make installworld' is required. 50# 51# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 52# update the legacy support for aout. This includes all libraries, ld.so 53# and boot objects. This part of build should be regarded as 54# deprecated and you should _not_ expect to be able to do this past the 55# release of 4.0. You have exactly one major release to move entirely 56# to elf. 57# 58# ---------------------------------------------------------------------------- 59# 60# Upgrading an i386 system from a.out to elf format 61# 62# 63# The aout->elf transition build is performed by doing a `make upgrade' (or 64# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 65# by a `make aout-to-elf-install', depending on user preference. 66# You need to have at least 320 Mb of free space for the object tree. 67# 68# The upgrade process checks the installed release. If this is 3.0-CURRENT, 69# it is assumed that your kernel contains all the syscalls required by the 70# current sources. 71# 72# The upgrade procedure will stop and ask for confirmation to proceed 73# several times. On each occasion, you can type Ctrl-C to abort the 74# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 75# the confirmation steps. 76# 77# At the end of the upgrade procedure, /etc/objformat is created or 78# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 79# 80# ---------------------------------------------------------------------------- 81# 82# 83# Define the user-driven targets.
