Hi,

After doing this workaround, I'm able to compile the userspace part of
Xenomai, but now I can't compile any little kernelmodule using the
xenomai api. I attached the Makefile and the sourcecode of my little
example.
When trying to compile it cannot find headers like asm/param.h or
asm/types.h (because they are not in krnsrc/include/asm-ppc/ and the
workaround just added the userspace/libc headers). I guess there must be
something wrong with the Makefile, but I cannot find the problem.
regards,
