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# If you want to build your system from source be sure that /usr/obj has 36# at least 400MB of diskspace available. 37# 38# For individuals wanting to build from the sources currently on their 39# system, the simple instructions are: 40# 41# 1. `cd /usr/src' (or to the directory containing your source tree). 42# 2. `make world' 43# 44# For individuals wanting to upgrade their sources (even if only a 45# delta of a few days): 46# 47# 1. `cd /usr/src' (or to the directory containing your source tree). 48# 2. `make buildworld' 49# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 50# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 51# 5. `reboot' (in single user mode: boot -s from the loader prompt). 52# 6. `mergemaster -p' 53# 7. `make installworld' 54# 8. `mergemaster' 55# 9. `reboot' 56# 57# See src/UPDATING `COMMON ITEMS' for more complete information. 58# 59# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will 60# update the legacy support for aout. This includes all libraries, ld.so 61# and boot objects. This part of build should be regarded as 62# deprecated and you should _not_ expect to be able to do this past the 63# release of 4.0. You have exactly one major release to move entirely 64# to elf. 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# At the end of the upgrade procedure, /etc/objformat is created or 86# updated to contain OBJFORMAT=elf. From then on, you're elf by default. 87# 88# ---------------------------------------------------------------------------- 89# 90# 91# Define the user-driven targets.
