(http://lists.debian.org/debian-deve...9/msg01362.html)?
I am very interested in this project and have a little bit of time to

Pity I've read about this only now 
Making support for such additional 'archs', targeting mainly uclibc archs,
is *the* direction where I was going to move with dpkg-cross and debian
cross-toolchain (I'm the current maintainer of those).
Unfortunatly, I have bad times regadring to free time last months...
But I'll be happy to see any needed support added to dpkg-cross and debian
cross-toolchain patches; I'll do my best to support any related effort.
Nikita
P.S.
Long-promised dpkg-cross upload is 85%-ready and in CVS, the only thing not
coded yet is additional provides-depends to avoid collisions between old
and new cross-compiling trees that I've explained in previous mails.

This is also a way we're currently moving in our version of embedded Debian=
..
We used to use a regular-dpkg-arch-depending-on-uclibc approach, but met lo=
ts
of problems with it, and got away to new dpkg architectures.

| Guys:
Regarding this:
http://lists.debian.org/debian-deve...9/msg01362.html
I would be very interested in mips and arm-el ports. I have dedicated
build hardware available for both. PLEASE let me know what else I can
do to help!
(I've tinkered with dpkg in the past, but I'm no guru. Hardly even a
noob, in fact).
Thanks!
b.g.

Well I do think i386-uclibc will help another subarches, like arm-uclibc
armeb-uclibc, mips-uclibc and so on...
One thing I failed was building a toolchain for a subarch inside my own
system (without chrooting)... This would help everybody to get the base
+build-essential packages faster.
I'm just moving because I gave up on this and started using
gentoo-embedded as a start. If someone could solve this, it would be
really nice...

Well,
This is exactly what i386-uclibc is all about...
I had a hard time building a toolchain inside debian for i386-uclibc, so
I gave up and now I'm using gentoo-embedded as a seed to this new arch.
Enerv is working on a move from gentoo stage1 to 3 again because they
choosed to make the architecture i386-gentoo-linux-uclibc instead of
i386-pc-linux-uclibc. But besides that problem, I made dpkg understands
the i386-uclibc architecture, in a not-so-good way... but it seems to
work (only with dpkg 1.13).
BTW, this is what I have now inside my gentoo-embedded chroot...

I needed to patch dpkg in some ways (including configure) to support
sub-arches. It's working, but I really would like to see a better
solution.
What I made was... If it's a linux-uclibc os, sticks to $cpu-uclibc...
I'm now working on discovering the best order to build the 87 needed
source packages to get a base+buildessential set for debootstrap.
Follows the patches I made on dpkg...

Please see the other posts I made in this thread for more info. I just
wanted to point that I'm almost all the time (when working on this) on
#debian-devel #gentoo-embedded and #uclibc and making regular questions
in these channels ;). look for ruoso and you'll find me.

I believe this should be done on normal debian host, using dpkg-cross's
'dpkg-buildpackage -a'. As of it's current state, it won't work. But it
could be made to  .
To make it work, at least following is needed:
- dpkg-architecture should know about the arch (as far as I understood, you
have a version that does?)
- there are some arch tables in dpkg-cross tools (probably some of them
should be killed, in flavour of a howto about adding new archs to
dpkg-architecture); i386-uclibc should be added there;
- i386-linux-uclibc-{gcc,ld,as,...} should be availbale
- dpkg-cross'ed build depends should be installed
- maybe start with something that does not have other build-deps than
libc, which should be satisfied by uclibc
- can debian uclibc packages be just dpkg-cross'ed? or a hand-made
libuclibc{0,dev}-i386-uclibc-cross is needed?
Probably these thoughts are incomplete...

| Subscribe to i386-uclibc and join #debian-i386-uclibc channel. The
uclibc-pc-linux-uclibc and binutils-pc-linux-uclibc are already done. Now we
are working on gcc-pc-linux-uclibc package.
