# $FreeBSD$
# The user-driven targets are:
# universe - *Really* build *everything* (buildworld and
# all kernels on all architectures).
# tinderbox - Same as universe, but presents a list of failed build
# targets and exits with an error if there were any.
# 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.
# kernel-toolchain - Builds the subset of world necessary to build a kernel
# kernel-toolchains - Build kernel-toolchain for all universe targets.
# doxygen - Build API documentation of the kernel, needs doxygen.
# update - Convenient way to update your source tree(s).
# 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.
# delete-old-dirs - Delete obsolete directories.
# delete-old-files - Delete obsolete files.
# delete-old-libs - Delete obsolete libraries.
# targets - Print a list of supported TARGET/TARGET_ARCH pairs
# for world and kernel targets.
# toolchains - Build a toolchain for all world and kernel targets.
# xdev - xdev-build + xdev-install for the architecture
# specified with XDEV and XDEV_ARCH.
# xdev-build - Build cross-development tools.
# xdev-install - Install cross-development tools.
# xdev-links - Create traditional links in /usr/bin for cc, etc
# native-xtools - Create host binaries that produce target objects
# for use in qemu user-mode jails.
# "quick" way to test all kernel builds:
# _jflag=`sysctl -n hw.ncpu`
# _jflag=$(($_jflag * 2))
# [ $_jflag -gt 12 ] && _jflag=12
# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag}
# 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.
# Most of the user-driven targets (as listed above) are implemented in
# Makefile.inc1. The exceptions are universe, tinderbox and targets.
# If you want to build your system from source be sure that /usr/obj has
# at least 1GB of diskspace available. A complete 'universe' build requires
# about 15GB of space.
# 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. `mergemaster' (you may wish to use -i, along with -U or -F).
# 9. `make delete-old'
# 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. powerpc, 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.
