1# 2# $FreeBSD: head/Makefile 103985 2002-09-26 04:40:54Z phk $ 3# 4# The user-driven targets are: 5# 6# universe - *Really* build *everything*: Buildworld and 7# all kernels on all architectures. 8# buildworld - Rebuild *everything*, including glue to help do 9# upgrades. 10# installworld - Install everything built by "buildworld". 11# world - buildworld + installworld. 12# buildkernel - Rebuild the kernel and the kernel-modules. 13# installkernel - Install the kernel and the kernel-modules. 14# reinstallkernel - Reinstall the kernel and the kernel-modules. 15# kernel - buildkernel + installkernel. 16# update - Convenient way to update your source tree (cvs). 17# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way 18# most - Build user commands, no libraries or include files. 19# installmost - Install user commands, no libraries or include files. 20# aout-to-elf - Upgrade an system from a.out to elf format (see below). 21# aout-to-elf-build - Build everything required to upgrade a system from 22# a.out to elf format (see below). 23# aout-to-elf-install - Install everything built by aout-to-elf-build (see 24# below). 25# move-aout-libs - Move the a.out libraries into an aout sub-directory 26# of each elf library sub-directory. 27# 28# This makefile is simple by design. The FreeBSD make automatically reads 29# the /usr/share/mk/sys.mk unless the -m argument is specified on the 30# command line. By keeping this makefile simple, it doesn't matter too 31# much how different the installed mk files are from those in the source 32# tree. This makefile executes a child make process, forcing it to use 33# the mk files from the source tree which are supposed to DTRT. 34# 35# The user-driven targets (as listed above) are implemented in Makefile.inc1. 36# 37# If you want to build your system from source be sure that /usr/obj has 38# at least 400MB of diskspace available. 39# 40# For individuals wanting to build from the sources currently on their 41# system, the simple instructions are: 42# 43# 1. `cd /usr/src' (or to the directory containing your source tree). 44# 2. `make world' 45# 46# For individuals wanting to upgrade their sources (even if only a 47# delta of a few days): 48# 49# 1. `cd /usr/src' (or to the directory containing your source tree). 50# 2. `make buildworld' 51# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 52# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 53# 5. `reboot' (in single user mode: boot -s from the loader prompt). 54# 6. `mergemaster -p' 55# 7. `make installworld' 56# 8. `mergemaster' 57# 9. `reboot' 58# 59# See src/UPDATING `COMMON ITEMS' for more complete information. 60# 61# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can 62# cross build world for other architectures using the buildworld target, 63# and once the world is built you can cross build a kernel using the 64# buildkernel target. 65# 66# ---------------------------------------------------------------------------- 67# 68# Upgrading an i386 system from a.out to elf format 69# 70# 71# The aout->elf transition build is performed by doing a `make upgrade' (or 72# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed 73# by a `make aout-to-elf-install', depending on user preference. 74# You need to have at least 320 Mb of free space for the object tree. 75# 76# The upgrade process checks the installed release. If this is 3.0-CURRENT, 77# it is assumed that your kernel contains all the syscalls required by the 78# current sources. 79# 80# The upgrade procedure will stop and ask for confirmation to proceed 81# several times. On each occasion, you can type Ctrl-C to abort the 82# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip 83# the confirmation steps. 84# 85# ---------------------------------------------------------------------------- 86# 87# 88# Define the user-driven targets.
