# $FreeBSD: src/Makefile,v 1.358. 2009/10/25 01:10:29 kensmith Exp $
# The user-driven targets are:
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld, no kernel.
# buildkernel - Rebuild the kernel and the kernel-modules.
# installkernel - Install the kernel and the kernel-modules.
# installkernel.debug
# reinstallkernel - Reinstall the kernel and the kernel-modules.
# reinstallkernel.debug
# kernel - buildkernel + installkernel.
# doxygen - Build API documentation of the kernel, needs doxygen.
# update - Convenient way to update your source tree (cvs).
# check-old - List obsolete directories/files/libraries.
# check-old-dirs - List obsolete directories.
# check-old-files - List obsolete files.
# check-old-libs - List obsolete libraries.
# delete-old - Delete obsolete directories/files/libraries.
# delete-old-dirs - Delete obsolete directories.
# delete-old-files - Delete obsolete files.
# delete-old-libs - Delete obsolete libraries.
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/ unless the -m argument is specified on the
# command line. By keeping this makefile simple, it doesn't matter too
# much how different the installed mk files are from those in the source
# tree. This makefile executes a child make process, forcing it to use
# the mk files from the source tree which are supposed to DTRT.
# The user-driven targets (as listed above) are implemented in Makefile.inc1.
# If you want to build your system from source be sure that /usr/obj has
# at least 800MB of diskspace available.
# For individuals wanting to build from the sources currently on their
# system, the simple instructions are:
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README).
# 3. `make world'
# For individuals wanting to upgrade their sources (even if only a
# delta of a few days):
# 1. `cd /usr/src' (or to the directory containing your source tree).
# 2. `make buildworld'
# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC).
# [steps 3. & 4. can be combined by using the "kernel" target]
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `make delete-old'
# 9. `mergemaster' (you may wish to use -U or -ai).
# 10. `reboot'
# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore)
# See src/UPDATING `COMMON ITEMS' for more complete information.
# If TARGET=machine (e.g. ia64, sparc64, ...) is specified you can
# cross build world for other machine types using the buildworld target,
# and once the world is built you can cross build a kernel using the
# buildkernel target.
# Define the user-driven targets. These are listed here in alphabetical
# order, but that's not important.
# Targets that begin with underscore are internal targets intended for
# developer convenience only. They are intentionally not documented and
# completely subject to change without notice.
# For more information, see the build(7) manual page.
