Cross compile problem (gcc-3.2.1, glibc-2.3.1)

[Zoltan Csizmadia]

Hi All,

I try to cross compile a toolchain for ARM (DNP1110).
When It tries to compile glibc, it doesn't find the
headers (stdio.h, unistd.h). It seems there is no
.../arm-linux/include directory
(.../arm-linux/sys-include is created though). When is
it created?

My build-toolchain script is attached.

Regards,

Zoltan
