Interesting - are you porting it to the free telephony project box?
...just curious what runs a Blackfin that you'd actually use a
console on.  :-)

Other folks have answered your questions about library dependencies,
so I'll tackle this one:

...or perhaps you've not ever cross-compiled a program using the
autoconf stuff before :-) If your build system is so configured, and
the autoconf junk works correctly, you should be able to use the
option '--host=bfin-uclinux' (or whatever - this should be correct,
if your toolchain starts with bfin-uclinux-<toolname>) to
./configure and it'll set up all of this stuff magically.  If you
already knew this, tried it, and it failed I apologize - but since
you didn't mention it, I'm assuming that you did not.  If everything
is set up right, this should automatically pull in your include
directories, etc - you may have to use the
--with-<library>-includes=<PREFIX> and
--with-<library>-libs=<PREFIX> flags, if you have dependencies
installed in crazy places, but you might not.

Hope this helps,
