# The user-driven targets are:
#
# buildworld - Rebuild *everything*, including glue to help do
# upgrades.
# installworld - Install everything built by "buildworld".
# world - buildworld + installworld.
# buildkernel - Rebuild the kernel and the kernel-modules.
# installkernel - Install the kernel and the kernel-modules.
# reinstallkernel - Reinstall the kernel and the kernel-modules.
# kernel - buildkernel + installkernel.
# update - Convenient way to update your source tree (cvs).
# upgrade - Upgrade a.out (2.2.x/3.0) system to the new ELF way
# most - Build user commands, no libraries or include files.
# installmost - Install user commands, no libraries or include files.
# aout-to-elf - Upgrade an system from a.out to elf format (see below).
# aout-to-elf-build - Build everything required to upgrade a system from
# a.out to elf format (see below).
# aout-to-elf-install - Install everything built by aout-to-elf-build (see
# below).
# move-aout-libs - Move the a.out libraries into an aout sub-directory
# of each elf library sub-directory.
#
# 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.
#
# 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 400MB 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. `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).
# 5. `reboot' (in single user mode: boot -s from the loader prompt).
# 6. `mergemaster -p'
# 7. `make installworld'
# 8. `mergemaster'
# 9. `reboot'
#
# See src/UPDATING `COMMON ITEMS' for more complete information.
#
# If -DWANT_AOUT is specified, a `make world' with OBJFORMAT=elf will
# update the legacy support for aout. This includes all libraries, ld.so
# and boot objects. This part of build should be regarded as
# deprecated and you should _not_ expect to be able to do this past the
# release of 4.0. You have exactly one major release to move entirely
# to elf.
#
2002-06-24 20:13:09 +00:00
# If TARGET_ARCH=arch (e.g. ia64, sparc64, ...) is specified you can
2002-06-24 05:14:54 +00:00
# cross build world for other architectures using the buildworld target,
# and once the world is built you can cross build a kernel using the
# buildkernel target.
#
# ----------------------------------------------------------------------------
#
# Upgrading an i386 system from a.out to elf format
#
#
# The aout->elf transition build is performed by doing a `make upgrade' (or
# `make aout-to-elf') or in two steps by a `make aout-to-elf-build' followed
# by a `make aout-to-elf-install', depending on user preference.
# You need to have at least 320 Mb of free space for the object tree.
#
# The upgrade process checks the installed release. If this is 3.0-CURRENT,
# it is assumed that your kernel contains all the syscalls required by the
# current sources.
#
# The upgrade procedure will stop and ask for confirmation to proceed
# several times. On each occasion, you can type Ctrl-C to abort the
# upgrade. Optionally, you can also start it with NOCONFIRM=yes and skip
# the confirmation steps.
#
# At the end of the upgrade procedure, /etc/objformat is created or
# updated to contain OBJFORMAT=elf. From then on, you're elf by default.

# order, but that's not important.

Milestone #1 in cross-arch make releases. Do not install games and profiled libraries to the ${CHROOTDIR} with the initial installworld. Eliminate the need in the second installworld. For that, make sure _everything_ is built in the "world" environment, using the right tool chain. Added SUBDIR_OVERRIDE helper stuff to Makefile.inc1. Split the buildworld process into stages, and skip some stages when SUBDIR_OVERRIDE is set (used to build crypto, krb4, and krb5 dists). Added NO_MAKEDB_RUN knob to Makefile.inc1 to avoid running makewhatis(1) at the end of installworld (used when making crypto, krb4, and krb5 dists). In release/scripts/doFS.sh, ensure that the correct boot blocks are used. Moved the creation of the "crypto" dist from release.5 to release.2. In release.3 and doMFSKERN, build kernels in the "world" environment. KERNELS now means "additional" kernels, GENERIC is always built. Ensure we build crunched binaries in the "world" environment. Obfuscate release/Makefile some more (WMAKEENV) to achieve this. Inline createBOOTMFS target. Use already built GENERIC kernel modules to augment mfsfd's /stand/modules. GC doMODULES as such. Assorted fixes: Get rid of the "afterdistribute" target by moving the single use of it from sys/Makefile to etc/Makefile's "distribute". Makefile.inc1: apparently "etc" no longer needs to be last for "distribute" to succeed. gnu/usr.bin/perl/library/Makefile.inc: do not override the "install" and "distribute" targets, do it the "canonical" way. release/scripts/{man,cat}pages-make.sh: make sure Perl manpages and catpages appear in the right dists. Note that because Perl does not respect the MANBUILDCAT (and NOMAN), this results in a loss of /usr/share/perl/man/cat* empty directories. This will be fixed soon. Turn MAKE_KERBEROS4 into a plain boolean variable (if it is set it means "make KerberosIV"), as documented in the make.conf(5) manpage. Most of the userland makefiles did not test it for "YES" anyway. XXX Should specialized kerberized libpam versions be included into the krb4 and krb5 dists? (libpam.a would be incorrect anyway if both krb4 and krb5 dists were choosen.) Make sure "games" dist is made before "catpages", otherwise games catpages settle in the wrong dist.
