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# kernel - buildkernel + installkernel. 14# update - Convenient way to update your source tree (cvs). 15# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 16# most - Build user commands, no libraries or include files. 17# installmost - Install user commands, no libraries or include files. 18# aout-to-elf - Upgrade an system from a.out to elf format (see below). 19# aout-to-elf-build - Build everything required to upgrade a system from 20# a.out to elf format (see below). 21# aout-to-elf-install - Install everything built by aout-to-elf-build (see 22# below). 23# move-aout-libs - Move the a.out libraries into an aout sub-directory 24# of each elf library sub-directory. 25# 26# This makefile is simple by design. The FreeBSD make automatically reads 27# the /usr/share/mk/sys.mk unless the -m argument is specified on the 28# command line. By keeping this makefile simple, it doesn't matter too 29# much how different the installed mk files are from those in the source 30# tree. This makefile executes a child make process, forcing it to use 31# the mk files from the source tree which are supposed to DTRT. 32# 33# The user-driven targets (as listed above) are implemented in Makefile.inc1. 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. 56# 57# ---------------------------------------------------------------------------- 58# 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. 78# 79# ---------------------------------------------------------------------------- 80# 81# 82# Define the user-driven targets.
