There is confusion here. I did not propose (did not mean to
propose) a solution; by "stock" I meant that you used a kernel
*and patches* other than those included or mentioned in the
devboard_lx release. So "stock 2.4.14" would mean a 2.4.14
kernel without the patches in devboard_lx-2.1.0.

From what I could understand from your attachment, there were
errors resulting from the "install" script trying to patch the
2.4.19 kernel with patches for 2.4.14. You need to at least
remove the code in the "install" script that applies that patch,
so that you use 2.4.19 *without* patches. I don't know if that

The problems you describe are unrelated to the compiler version.
I doubt there are any cris-dist-problems compiling 2.4.19; we
use it locally without problems. You are probably rather
looking for a devboard_lx release.

This suggestion (answer 2) together with the include files
suggestion in a later message sounds like a working solution.
