[Xenomai-help] problems building xenomai 2.1 for ppc

[Landau, Bracha]

I'm trying to build xenomai 2.1 for an 8272 architecture using kernel 2.6.14.
I've successfully put in the adeos patch.
Here are the problems I've encountered.

1) When doing ./scripts/prepare-kernel.sh I get an error that it can't find the file /include/asm-powerpc/ipipe.h.
I copied the file ipipe.h from /include/asm-ppc and reran prepare-kernel.sh with no errors.

2) After doing the above and configuring the "prepared" kernel for running with xenomai, I tried to build the kernel. I got link errors doing it. An example of such a link error is:

kernel/built-in.o: In function 'rthal_init':
:undefined reference to 'rthal_arch_init'


(The list is much longer - many undefined references of this sort.)

Any ideas what the problem may be?

You don't need to move kernel files around manually (actually, this 
almost never works properly). Please have a look at README.INSTALL, 
section 1 "Preparing the target kernel".
