# $FreeBSD$
#
# The user-driven targets are:
#
# universe            - *Really* build *everything* (buildworld and
#                       all kernels on all architectures).  Define
#                       MAKE_JUST_KERNELS or WITHOUT_WORLDS to only build kernels,
#                       MAKE_JUST_WORLDS or WITHOUT_KERNELS to only build userland.
# tinderbox           - Same as universe, but presents a list of failed build
#                       targets and exits with an error if there were any.
# worlds	      - Same as universe, except just makes the worlds.
# kernels	      - Same as universe, except just makes the kernels.
# 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).
# checkworld          - Run test suite on installed world.
# 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.
# makeman             - Regenerate src.conf(5)
# sysent              - (Re)build syscall entries from syscalls.master.
# xdev                - xdev-build + xdev-install for the architecture
#                       specified with TARGET and TARGET_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.  TARGET and
#                       TARGET_ARCH should be defined.
# native-xtools-install
#                     - Install the files to the given DESTDIR/NXTP where
#                       NXTP defaults to /nxb-bin.
#
# This makefile is simple by design. The FreeBSD make automatically reads
# the /usr/share/mk/sys.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 6 GB of disk space available.  A complete 'universe' build of
# r340283 (2018-11) required 167 GB of space.  ZFS lz4 compression
# achieved a 2.18x ratio, reducing actual space to 81 GB.
#
# 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)
#
# For individuals wanting to build from source with GCC from ports, first
# install the appropriate GCC cross toolchain package:
#   `pkg install ${TARGET_ARCH}-gccN`
#
# Once you have installed the necessary cross toolchain, simply pass
# CROSS_TOOLCHAIN=${TARGET_ARCH}-gccN while building with the above steps,
# e.g., `make buildworld CROSS_TOOLCHAIN=amd64-gcc6`.
#
# The ${TARGET_ARCH}-gccN packages are provided as flavors of the
# devel/freebsd-gccN ports.
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If TARGET=machine (e.g. powerpc, arm64, ...) 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.
