Makefile revision 57457
1# 2# $FreeBSD: head/Makefile 57457 2000-02-24 23:03:16Z markm $ 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# update - Convenient way to update your source tree (cvs). 11# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 12# most - Build user commands, no libraries or include files. 13# installmost - Install user commands, no libraries or include files. 14# aout-to-elf - Upgrade an system from a.out to elf format (see below). 15# aout-to-elf-build - Build everything required to upgrade a system from 16# a.out to elf format (see below). 17# aout-to-elf-install - Install everything built by aout-to-elf-build (see 18# below). 19# move-aout-libs - Move the a.out libraries into an aout sub-directory 20# of each elf library sub-directory. 21# 22# This makefile is simple by design. The FreeBSD make automatically reads 23# the /usr/share/mk/sys.mk unless the -m argument is specified on the 24# command line. By keeping this makefile simple, it doesn't matter too 25# much how different the installed mk files are from those in the source 26# tree. This makefile executes a child make process, forcing it to use 27# the mk files from the source tree which are supposed to DTRT. 28# 29# The user-driven targets (as listed above) are implemented in Makefile.inc0 30# and the private targets are in Makefile.inc1. These are kept separate 31# to help the bootstrap build from aout to elf format. 32# 33# For novices wanting to build from current sources, the simple instructions 34# are: 35# 36# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 37# 2. `cd /usr/src' (or to the directory containing your source tree). 38# 3. `make world' 39# 40# Be warned, this will update your installed system, except for configuration 41# files in the /etc directory and for the kernel. You have to do those manually. 42# 43# If at first you're a little nervous about having a `make world' update 44# your system, a `make buildworld' will build everything in the /usr/obj 45# tree without touching your installed system. To be of any further use 46# though, a `make installworld' is required. 47# 48# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 49# update the legacy support for aout. This includes all libraries, ld.so 50# and boot objects. This part of build should be regarded as 51# deprecated and you should _not_ expect to be able to do this past the 52# release of 4.0. You have exactly one major release to move entirely 53# to elf. 54# 55# ---------------------------------------------------------------------------- 56# 57# Upgrading an i386 system from a.out to elf format 58# 59# 60# The aout->elf transition build is performed by doing a `make upgrade' (or 61# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 62# by a `make aout-to-elf-install', depending on user preference. 63# You need to have at least 320 Mb of free space for the object tree. 64# 65# The upgrade process checks the installed release. If this is 3.0-CURRENT, 66# it is assumed that your kernel contains all the syscalls required by the 67# current sources. 68# 69# The upgrade procedure will stop and ask for confirmation to proceed 70# several times. On each occasion, you can type Ctrl-C to abort the 71# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 72# the confirmation steps. 73# 74# At the end of the upgrade procedure, /etc/objformat is created or 75# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 76# 77# ---------------------------------------------------------------------------- 78# 79# 80# Define the user-driven targets.
