155714Skris# 255714Skris# $FreeBSD: head/Makefile 73349 2001-03-02 16:52:14Z ru $ 355714Skris# 455714Skris# The user-driven targets are: 555714Skris# 655714Skris# buildworld - Rebuild *everything*, including glue to help do 755714Skris# upgrades. 855714Skris# installworld - Install everything built by "buildworld". 955714Skris# world - buildworld + installworld. 1055714Skris# buildkernel - Rebuild the kernel and the kernel-modules. 1176866Skris# installkernel - Install the kernel and the kernel-modules. 1255714Skris# reinstallkernel - Reinstall the kernel and the kernel-modules. 1355714Skris# kernel - buildkernel + installkernel 1455714Skris# update - Convenient way to update your source tree (cvs). 1555714Skris# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 1655714Skris# most - Build user commands, no libraries or include files. 1755714Skris# installmost - Install user commands, no libraries or include files. 1855714Skris# aout-to-elf - Upgrade an system from a.out to elf format (see below). 1955714Skris# aout-to-elf-build - Build everything required to upgrade a system from 2055714Skris# a.out to elf format (see below). 2155714Skris# aout-to-elf-install - Install everything built by aout-to-elf-build (see 2255714Skris# below). 2355714Skris# move-aout-libs - Move the a.out libraries into an aout sub-directory 2455714Skris# of each elf library sub-directory. 2555714Skris# 2655714Skris# This makefile is simple by design. The FreeBSD make automatically reads 2755714Skris# the /usr/share/mk/sys.mk unless the -m argument is specified on the 2855714Skris# command line. By keeping this makefile simple, it doesn't matter too 2955714Skris# much how different the installed mk files are from those in the source 3055714Skris# tree. This makefile executes a child make process, forcing it to use 3155714Skris# the mk files from the source tree which are supposed to DTRT. 3255714Skris# 3355714Skris# The user-driven targets (as listed above) are implemented in Makefile.inc0 3455714Skris# and the private targets are in Makefile.inc1. These are kept separate 3555714Skris# to help the bootstrap build from aout to elf format. 3655714Skris# 3755714Skris# For novices wanting to build from current sources, the simple instructions 3855714Skris# are: 3955714Skris# 4055714Skris# 1. Ensure that your /usr/obj directory has at least 260 Mb of free space. 4155714Skris# 2. `cd /usr/src' (or to the directory containing your source tree). 4255714Skris# 3. `make world' 4355714Skris# 4455714Skris# Be warned, this will update your installed system, except for configuration 4555714Skris# files in the /etc directory and for the kernel. You have to do those manually. 4655714Skris# 4755714Skris# If at first you're a little nervous about having a `make world' update 4855714Skris# your system, a `make buildworld' will build everything in the /usr/obj 4955714Skris# tree without touching your installed system. To be of any further use 5055714Skris# though, a `make installworld' is required. 5155714Skris# 5255714Skris# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 5355714Skris# update the legacy support for aout. This includes all libraries, ld.so 5455714Skris# and boot objects. This part of build should be regarded as 5555714Skris# deprecated and you should _not_ expect to be able to do this past the 5655714Skris# release of 4.0. You have exactly one major release to move entirely 5755714Skris# to elf. 5855714Skris# 5955714Skris# ---------------------------------------------------------------------------- 6055714Skris# 6155714Skris# Upgrading an i386 system from a.out to elf format 6255714Skris# 6355714Skris# 6455714Skris# The aout->elf transition build is performed by doing a `make upgrade' (or 6555714Skris# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 6655714Skris# by a `make aout-to-elf-install', depending on user preference. 6755714Skris# You need to have at least 320 Mb of free space for the object tree. 6855714Skris# 6955714Skris# The upgrade process checks the installed release. If this is 3.0-CURRENT, 7055714Skris# it is assumed that your kernel contains all the syscalls required by the 7155714Skris# current sources. 7255714Skris# 7355714Skris# The upgrade procedure will stop and ask for confirmation to proceed 7455714Skris# several times. On each occasion, you can type Ctrl-C to abort the 7555714Skris# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 7655714Skris# the confirmation steps. 7755714Skris# 7855714Skris# At the end of the upgrade procedure, /etc/objformat is created or 7955714Skris# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 8055714Skris# 8155714Skris# ---------------------------------------------------------------------------- 8255714Skris# 8355714Skris# 8455714Skris# Define the user-driven targets.
