10Sduke# 210248Smikael# $FreeBSD: head/Makefile 98723 2002-06-24 05:14:54Z dillon $ 30Sduke# 40Sduke# The user-driven targets are: 50Sduke# 60Sduke# buildworld - Rebuild *everything*, including glue to help do 70Sduke# upgrades. 80Sduke# installworld - Install everything built by "buildworld". 90Sduke# world - buildworld + installworld. 100Sduke# buildkernel - Rebuild the kernel and the kernel-modules. 110Sduke# installkernel - Install the kernel and the kernel-modules. 120Sduke# reinstallkernel - Reinstall the kernel and the kernel-modules. 130Sduke# kernel - buildkernel + installkernel. 140Sduke# update - Convenient way to update your source tree (cvs). 150Sduke# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 160Sduke# most - Build user commands, no libraries or include files. 170Sduke# installmost - Install user commands, no libraries or include files. 180Sduke# aout-to-elf - Upgrade an system from a.out to elf format (see below). 191472Strims# aout-to-elf-build - Build everything required to upgrade a system from 201472Strims# a.out to elf format (see below). 211472Strims# aout-to-elf-install - Install everything built by aout-to-elf-build (see 220Sduke# below). 230Sduke# move-aout-libs - Move the a.out libraries into an aout sub-directory 240Sduke# of each elf library sub-directory. 251879Sstefank# 261879Sstefank# This makefile is simple by design. The FreeBSD make automatically reads 2713249Sstefank# the /usr/share/mk/sys.mk unless the -m argument is specified on the 281879Sstefank# command line. By keeping this makefile simple, it doesn't matter too 290Sduke# much how different the installed mk files are from those in the source 300Sduke# tree. This makefile executes a child make process, forcing it to use 310Sduke# the mk files from the source tree which are supposed to DTRT. 320Sduke# 330Sduke# The user-driven targets (as listed above) are implemented in Makefile.inc1. 340Sduke# 350Sduke# If you want to build your system from source be sure that /usr/obj has 360Sduke# at least 400MB of diskspace available. 370Sduke# 380Sduke# For individuals wanting to build from the sources currently on their 390Sduke# system, the simple instructions are: 400Sduke# 410Sduke# 1. `cd /usr/src' (or to the directory containing your source tree). 420Sduke# 2. `make world' 430Sduke# 440Sduke# For individuals wanting to upgrade their sources (even if only a 450Sduke# delta of a few days): 460Sduke# 470Sduke# 1. `cd /usr/src' (or to the directory containing your source tree). 480Sduke# 2. `make buildworld' 490Sduke# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 500Sduke# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 510Sduke# 5. `reboot' (in single user mode: boot -s from the loader prompt). 520Sduke# 6. `mergemaster -p' 531523Skvn# 7. `make installworld' 540Sduke# 8. `mergemaster' 550Sduke# 9. `reboot' 560Sduke# 5710248Smikael# See src/UPDATING `COMMON ITEMS' for more complete information. 5810248Smikael# 5910248Smikael# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 6013128Smikael# update the legacy support for aout. This includes all libraries, ld.so 6113128Smikael# and boot objects. This part of build should be regarded as 6213128Smikael# deprecated and you should _not_ expect to be able to do this past the 6310248Smikael# release of 4.0. You have exactly one major release to move entirely 6410248Smikael# to elf. 6510248Smikael# 6610248Smikael# If -DTARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can 6710248Smikael# cross build world for other architectures using the buildworld target, 6810248Smikael# and once the world is built you can cross build a kernel using the 6913128Smikael# buildkernel target. 7013128Smikael# 7110248Smikael# ---------------------------------------------------------------------------- 7210248Smikael# 7310248Smikael# Upgrading an i386 system from a.out to elf format 7410248Smikael# 7513243Sstefank# 7610248Smikael# The aout->elf transition build is performed by doing a `make upgrade' (or 7710248Smikael# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 7813128Smikael# by a `make aout-to-elf-install', depending on user preference. 7910248Smikael# You need to have at least 320 Mb of free space for the object tree. 8010248Smikael# 8113128Smikael# The upgrade process checks the installed release. If this is 3.0-CURRENT, 8210248Smikael# it is assumed that your kernel contains all the syscalls required by the 8313128Smikael# current sources. 8410248Smikael# 8510248Smikael# The upgrade procedure will stop and ask for confirmation to proceed 8610248Smikael# several times. On each occasion, you can type Ctrl-C to abort the 8710248Smikael# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 8810248Smikael# the confirmation steps. 8910248Smikael# 9010248Smikael# At the end of the upgrade procedure, /etc/objformat is created or 9110248Smikael# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 9210248Smikael# 9310248Smikael# ---------------------------------------------------------------------------- 9410248Smikael# 9510248Smikael# 9610248Smikael# Define the user-driven targets.
