1# 2# $FreeBSD: head/Makefile 133942 2004-08-18 06:49:56Z ru $ 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# installkernel.debug 15# reinstallkernel - Reinstall the kernel and the kernel-modules. 16# reinstallkernel.debug 17# kernel - buildkernel + installkernel. 18# update - Convenient way to update your source tree (cvs). 19# 20# This makefile is simple by design. The FreeBSD make automatically reads 21# the /usr/share/mk/sys.mk unless the -m argument is specified on the 22# command line. By keeping this makefile simple, it doesn't matter too 23# much how different the installed mk files are from those in the source 24# tree. This makefile executes a child make process, forcing it to use 25# the mk files from the source tree which are supposed to DTRT. 26# 27# The user-driven targets (as listed above) are implemented in Makefile.inc1. 28# 29# If you want to build your system from source be sure that /usr/obj has 30# at least 400MB of diskspace available. 31# 32# For individuals wanting to build from the sources currently on their 33# system, the simple instructions are: 34# 35# 1. `cd /usr/src' (or to the directory containing your source tree). 36# 2. `make world' 37# 38# For individuals wanting to upgrade their sources (even if only a 39# delta of a few days): 40# 41# 1. `cd /usr/src' (or to the directory containing your source tree). 42# 2. `make buildworld' 43# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 44# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 45# 5. `reboot' (in single user mode: boot -s from the loader prompt). 46# 6. `mergemaster -p' 47# 7. `make installworld' 48# 8. `mergemaster' 49# 9. `reboot' 50# 51# See src/UPDATING `COMMON ITEMS' for more complete information. 52# 53# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can 54# cross build world for other architectures using the buildworld target, 55# and once the world is built you can cross build a kernel using the 56# buildkernel target. 57# 58# Define the user-driven targets. These are listed here in alphabetical 59# order, but that's not important. 60# 61# Targets that begin with underscore are internal targets intended for 62# developer convenience only.
