error cross compiling ubi-utils

This happens with current git tree (git://git.infradead.org/mtd-utils.git)

building for HOST (i686, FC6) works fine.
cross compiling (for powerpc) fails because of this error:

To cross compile I set CROSS=/swdev/tools/linuxppc/gcc-4.2.4-glibc-2.7/powerpc-e300c3-linux/bin/powerpc-e300c3-linux- and issued make in mtd-utils directory.

The problem is that my powerpc cross compiler (gcc-2.7) doesn't define __be32 (nor __be16 and __be64) in the standard system headers (/swdev/tools/linuxppc/gcc-4.2.4-glibc-2.7/powerpc-e300c3-linux/powerpc-e300c3-linux/sys-include/asm/types.h).

For the HOST build "/usr/include/linux/types.h" is used which does define __be64/__be32/__be16.

I guess mtd-utils/include/mtd/ubi-media.h should use __u64/__u32/__u16 ?

I believe new kernels export these types via their headers, and you just have an old kernel. You could try to make mtd-utils be independent of these types.

You're right.
I didn't realize my "../sys-include/asm/types.h" comes from linux-libc-headers-2.6.12.0(/include/asm-ppc/types.h).
I guess I should've used more recent kernel headers when building my CDE.
