asterisk users - Nov 2007 - Cross-compiling asterisk-1.4 for Debian on a slug

Hi folks!

I planned to put asterisk-1.4 on my slug (one of these embedded devices).
Since i don't want to compile it natively on this slow processor, i need
a cross-compile toolchain. I tried out several ways such as manually
compiling binutils and gcc, or using scratchbox. All of these with the
result that i got binaries for machines except the one i wanted! :(

I then have been given a link to a optware tree specific to Debian on
the slug[1]. I tried to compile, but at the first attempt, it stopped
with this cruft:

I then removed the whole optware subdir and retried, this time with another
error (?):

make: *** [/home/user/down/optware/cs04q3armel/builds/asterisk14/.configured]

I then tried to build other packages such as arping, which could be compiled
without any problems and ran on my slug! Further, i compiled the asterisk
package for the nslu2 platform (instead of cs04q3armel), again without any
errors, but the resulting binaries did not run due endianess issues.
Debian/Slug is little-endian while most other nslu2-linuxes seem to be
big-endianed.

Could a friendly and helpful soul out there have a heart with me and tell
me how to produce a working package? Thanks in advance!

Greetings,
Fabiano

Hello? Nobody any idea how to fix that or how to compile asterisk-1.4 for
Debian/slug on an i686 machine? Or should i ask on the nslu2 mailing list?
