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.

This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information). The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel and the contents of /etc. Please see the top of the Makefile in this directory for more information on the standard build targets and compile-time flags. Building a kernel with config(8) is a somewhat more involved process, documentation for which can be found at: http://www.freebsd.org/handbook/kernelconfig.html And in the config(8) man page. The sample kernel configuration files reside in the sys/i386/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file LINT contains entries for all possible devices, not just those commonly used, and is meant more as a general reference than an actual kernel configuration file (a kernel built from it wouldn't even run).
