already used by the kernel makefiles themselves, and this leads to a lot
of trouble when people put "KERNEL=MYKERNEL" in make.conf. Bite the bullet
and change it to KERNCONF instead, before it gets too far entrenched.
The kernel Makefiles use ${KERNEL} as the name of what to install the
kernel as, eg: /boot/${KERNEL}/kernel or /${KERNEL}. This leads to much
unhappiness with things like /LOCAL instead of /kernel. buildkernel is
severely limited as it is only useful directly after a buildworld.

not right because rtermcap would be reading the *host* termcap, not
from the termcap in the src tree. Besides, /usr/sbin/sysinstall

The distribute target is basicly the same as an install. For
perl, this means that miniperl is needed. Since miniperl is
only present in the object directory, we need to make sure
the path is set correctly. To do this, we have make release

a make distribute.
o Move building libperl and miniperl from build-tools to
cross-tools. libperl uses MACHINE_ARCH to determine the
right configuration, which doesn't match the build
machine when cross-building if they are built as build-
tools.
o Since miniperl needs to be built as a cross-tool, it
needs to be installed under /usr/obj so that it can be
used (cross-tools have a special object directory to
avoid build conflicts. As a downside, you can't easily
run cross-tools from their object directory). Remove
the install and distribute override targets. To avoid
having miniperl installed by installworld, remove it
from SUBDIR.
o We can't pickup miniperl from the object directory but
since it's installed, depend on PATH. This is save,
because the makefiles are run with a known path.
o Build libperl again as part of the library target. A
_libperl variable existed, but it was never defined.
o Add chmod to the list of saved tools, because perl
conditionally uses it during install.
The bootstrap-tools and cross-tools targets are modified to
avoid building profiled and shared libraries. While here,
have these targets build static binaries instead of shared
binaries.

If a user decides to forego a make depend during "make buildkernel",
they should get what they deserve if no previous make depend has
been run for that kernel. Instead, the build process includes

buildworld now makes usr.sbin/config in bootstrap-tools so that
when you first make buildworld, buildkernel will use config(8)
from the temp. world tree (and of course also the compiler).
Which kernel to built is determined by the KERNEL variable. You
can have as many kernels listed as you like. When a config file
exists for the given MACHINE it will be built. When KERNEL has
not been defined it will be set to "GENERIC GENERIC98".
The first valid kernel named in the list will be used by the
installkernel target.
When NOCLEAN is defined the kernel object directory is *not*
removed by config first. This is in line with normal buildworld
behaviour.
The buildkernel target makes aicasm in sys/dev/aic7xxx first and
unconditionally. This hack allows us to cross-build kernels and
can go away when the problem is solved in a structural way.
If one wishes to anchor the compiler toolchain tree somewhere other than /,

o Add genassym to the list of cross-tools
o Remove sh hashing work-around, we don't need it anymore
o Clean more directories in WORLDTMP when NOCLEAN is specified
The sh hashing work-around is not needed anymore, because we don't
trigger the bug anymore.
When NOCLEAN is not defined, we wipe out the complete WORLDTMP,
including the object directories of the tools we have built. When
NOCLEAN is defined, we remove anything that we install anyway, which
is usr/bin, usr/games, usr/include, usr/lib and usr/sbin.

o Do not make build-tools for f771 when NO_FORTRAN is defined.
o Add new build stage. See below.
o Change banners so that staging information is displayed.
The addition of the build-tools target broke the upgrade path because
we couldn't make use of previously built tools that were made for
compatibility reasons. Doing so would also result in the cross-compiler
being used and that is exactly what had to be avoided.
This is solved by designating the bootstrap-tools stage for building
anything that is needed for compatibility only and to create a new
stage (started after the build-tools stage) that handles cross-tools
building. We now have the following stages:
1. bootstrap-tools (for compatibility issues only)
2. build-tools
3. cross-tools (what it says)
4. world
5. install
Stages 1-4 (inclusive) are handled by buildworld.
Stage 5 is handled by installworld.
Any more stages and I'll join Nik in his quest for the
holy grail^W^Wworld :-)
buildworld doesn't break because the host doesn't have any
games installed,
o Add a new build stage: TMAKE. TMAKE builds all the build-tools
targets in the respective makefiles. Note that these targets
don't use the bootstrap tools,
o Add elf2exe to the bootstrap-tools when cross-building Alpha on
other platforms,
o Add ${WORLDTMP}/usr/games to TMPPATH,
o Remove ${WORLDTMP}/usr/bin even when NOCLEAN is defined. This
prevents using any bootstrap-tools previously installed. Most
importantly, it prevents using the cross-compiler when we still
need the native compiler.
The current stages are BMAKE, TMAKE, XMAKE and IMAKE in that order.
BMAKE builds bootstrap-tools that either solve compatibility problems
or are needed as cross-tools,
TMAKE builds the support tools necessary by some parts in the source
tree and also performs the cleandir and par-obj targets,
XMAKE builds the includes, libraries and everything (resp.), and
IMAKE installs the world. This stage needs further work if it's to be
used to install -current over -stable for example.
This is the last major update towards cross-building.
o Don't set CFLAGS in the bootstrap env. It is very likely to be
overridden my any CFLAGS setting in /etc/make.conf. Setting it
here is almost useless. So far, it doesn't seem necessary.
o Build tools before doing anything in or with the object tree.
o Tools don't use the object tree any more, but have there object
tree located in the temp. world.
o Use the proper make env. for cleaning and building the object tree.
o Don't create kernel include subdirectories in the temp. world. These
are removed later on and replaced by symlinks.
o Change the layout of the object tree:
The temp. world now is /usr/obj/${MACHINE_ARCH}${.CURDIR}/${BUILD_ARCH}.
/usr/obj can be set/changed by using MAKEOBJDIRPREFIX, and {.CURDIR}
obviously depends on where the source tree is located. MACHINE_ARCH
is the arch. for which the world is to be build and BUILD_ARCH is the
arch. on which we are building.
The object tree now is /usr/obj/${MACHINE_ARCH}${.CURDIR}.
This allows concurrent cross-builds and allows the object tree to be
shared on different archs., each doing the same cross-build. This of
course assumes that the output on Alpha (for example) is the same as
the output of an Alpha cross-build on i386 (for example).
The use of NOCLEAN is is still dangerous, but should be usable in many
more situations than before. It should now be possible to safely
restart an interrupted build with NOCLEAN without side-effects. Because
the tools don't share the object tree with the normal (cross-build), no
tools have to be rebuild.

o Makefile.inc0 is not used anymore.

The problem with pre-Aug worlds is the installed Byacc and Bison doesn't

The problem with pre-GCC 2.95 worlds is libgcc is built with the wrong

This change solves the bug where build-tools, compiled against the
includes and libraries built from the sources failed to run on the
host, as was the case with the sigset_t change. With this update, a
buildworld will fail if the tools won't compile on the host. This
is solved in further commits where backward compatibility of the
tools is enlarged.
The libraries target has been fixed. The libraries are now build in
the proper order, satisfying the dependencies. The comment is updated
to reflect this.
The linux module and netboot have been removed from the list of tools.
