when you first make buildworld, buildkernel will use config(8)

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.

o Remove sh hashing work-around, we don't need it anymore

The sh hashing work-around is not needed anymore, because we don't

When NOCLEAN is not defined, we wipe out the complete WORLDTMP,

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.

This change solves the bug where build-tools, compiled against the

probably other versions by spamming ${DESTDIR}/usr/include in much
the same way as `make includes'.
Details for 2.2.7: the bootstrap target has always done a weak spam
of ${DESTDIR}/usr/include; we depend on it not installing any
significant anachronisms (it probably shouldn't touch the headers
at all; however, we may be depending on it for things like the
renaming of ts_nsec to ts_sec in <sys/time.h>). Rev.1.49 strengthens
the spam to everything in src/include. For 2.2.7, this is not
immediately fatal. However, the `make all' step in src/includes
is not followed by a `make clean' step, so new rpc headers are not
generated after we've bootstrapped rpcgen. This causes a fatal
error much later when the old (generated) rpc headers are used with
the current headers (sys/types.h and/or the non-generated rpc
headers).
Details for 2.1.x: the bug is immediately fatal. It gives definition
of errno that is not supported by 2.1.x's libc. The weak spam in the
restored version avoids this problem by not installing errno.h.
(Bootstrapping from 2.1.5 actually breaks much earlier.)
I think the header problems supposedly fixed by rev.1.49 were caused
by using NOCLEAN and having the build fall over when the weakly
spammed headers are active. Minor differences in the layout will
then cause the .depend files to point to nonexistent headers. It
is a feature for symlinks like errno.h -> sys/errno.h to not exist
early.
The other change in rev.1.49 breaks building obj directories if NOCLEAN
is set. It is only safe for _re_building with NOCLEAN set.
try and recurse if the lkm dir exists for some reason but there isn't any
Makefile there. (eg: stray files prevented cvs update -P from removing the

some tools requiring header files, such as errno.h, that are softlinks.
The mini installation of include files in Makefile.inc1 wasn't doing
the job, so it has been ripped out and replaced with a true make of the
/usr/src/include/ directory (make all and make beforeinstall). I think
the original idea was to save time by not installing unnecessary header
files, but it doesn't really save all that much time.
Also, I have moved a NOCLEAN conditional to cover rebuilding the object
tree 'Rebuilding the ${OBJFORMAT} obj tree' section. This may or may not
be correct but it appears to function properly. If it is not correct we
need to find another way to avoid scanning every single file in the
entire source hierarchy for make restarts.
Build the ordered list of libraries in a variable "_libs" before

- in the elf case, csu must be built and installed before any shared
libraries. It wasn't, but we usually used a stale version that
happened to work. E.g., in the !NOTOOLS case we used the version
built and installed by the bootstrap-libraries target. Only cross
building was completely broken.
- the shared libmd must be built and installed before any shared
libraries that link to it. It wasn't, but we sometimes used a stale
version that happened to work, as above. For elf, this caused
bogus linkage of the target shared libatm and libopie with the host
static libmd. It isn't clear what this actually breaks, except for
cross compiling. For aout, the shared libmd is not built at all, so
all shared libraries linked to libmd may be broken. The linker
reports them by spewing RRS warnings.
Note that building src/lib early and building subdirs of src/lib in
the correct order in src/lib/Makefile doesn't help, since the subdirs
are all built before any are installed.

HARP | Host ATM Research Platform
===================================
HARP 3
What is this stuff?
-------------------
The Advanced Networking Group (ANG) at the Minnesota Supercomputer Center,
Inc. (MSCI), as part of its work on the MAGIC Gigabit Testbed, developed
the Host ATM Research Platform (HARP) software, which allows IP hosts to
communicate over ATM networks using standard protocols. It is intended to
be a high-quality platform for IP/ATM research.
HARP provides a way for IP hosts to connect to ATM networks. It supports
standard methods of communication using IP over ATM. A host's standard IP
software sends and receives datagrams via a HARP ATM interface. HARP provides
functionality similar to (and typically replaces) vendor-provided ATM device
driver software.
HARP includes full source code, making it possible for researchers to
experiment with different approaches to running IP over ATM. HARP is
self-contained; it requires no other licenses or commercial software packages.
HARP implements support for the IETF Classical IP model for using IP over ATM
networks, including:
o IETF ATMARP address resolution client
o IETF ATMARP address resolution server
o IETF SCSP/ATMARP server
o UNI 3.1 and 3.0 signalling protocols
o Fore Systems's SPANS signalling protocol
What's supported
----------------
The following are supported by HARP 3:
o ATM Host Interfaces
- FORE Systems, Inc. SBA-200 and SBA-200E ATM SBus Adapters
- FORE Systems, Inc. PCA-200E ATM PCI Adapters
- Efficient Networks, Inc. ENI-155p ATM PCI Adapters
o ATM Signalling Protocols
- The ATM Forum UNI 3.1 signalling protocol
- The ATM Forum UNI 3.0 signalling protocol
- The ATM Forum ILMI address registration
- FORE Systems's proprietary SPANS signalling protocol
- Permanent Virtual Channels (PVCs)
o IETF "Classical IP and ARP over ATM" model
- RFC 1483, "Multiprotocol Encapsulation over ATM Adaptation Layer 5"
- RFC 1577, "Classical IP and ARP over ATM"
- RFC 1626, "Default IP MTU for use over ATM AAL5"
- RFC 1755, "ATM Signaling Support for IP over ATM"
- RFC 2225, "Classical IP and ARP over ATM"
- RFC 2334, "Server Cache Synchronization Protocol (SCSP)"
- Internet Draft draft-ietf-ion-scsp-atmarp-00.txt,
"A Distributed ATMARP Service Using SCSP"
o ATM Sockets interface
- The file atm-sockets.txt contains further information
What's not supported
--------------------
The following major features of the above list are not currently supported:
o UNI point-to-multipoint support
o Driver support for Traffic Control/Quality of Service
o SPANS multicast and MPP support
o SPANS signalling using Efficient adapters
This software was developed under the sponsorship of the Defense Advanced
Research Projects Agency (DARPA).

Another chance to architect people's principles...I can hardly wait. Seems
quite appropriate for a Sunday - I just need to get one of those collection
plates (and money envelopes) so I can profit, too. :-)
Tcl stays in /usr/src for now, but it needs to be kept up to date; same
for perl. If Jordan doesn't have "setup" (written in tcl) ready for 3.0,
then tcl will be yanked prior to the 3.0 release (and made into a port).
As for the ports tree only supporting the last FreeBSD release, this seems
sensible to me. The "ports" have always been a moving target between releases
and the problem is only going to get worse when we expand to supporting other
processor architectures. In any case, Satoshi is and always has been in charge
of the ports tree and whatever he wants to do with it (within reason :-)) is
his decision.
Does this cover the issue completely? I admit to deleting messages in this
thread with unusual fervor (people have FAR too much time on their hands!).
There's a fair bit of reasoning behind the above, but since everyone is sick
of arguing about this, I'll spare you the analysis.

shooting (a form of boot scooting for hackers?) where local changes
to /etc/make.conf or /etc/make.conf.local try to override OBJFORMAT
in an incomplete way.
- Moved most of the guts of Makefile to Makefile.inc1 to become the
backend for the build system.
- The new Makefile doesn't suffer from problems including the wrong
sys.mk because it doesn't use anything in there or bsd.own.mk. So,
from now on, the proper build command is just `make world' (or
buildworld).
- The intermediate makefiles called Makefile.inc0 and Makefile.upgrade
fiddle with the OBJFORMAT and MAKEOBJDIRPREFIX variables so that
both aout and elf object trees can coexist. Makefile.upgrade contains
the aout->elf transition build.
- A cross build environment is now very close to reality. Specifying
TOOLDIR, setting OBJFORMAT and MAKEOBJDIRPREFIX allow that.
See the comments in Makefile for more info.
