[Xenomai] failing compile of kernel-3.8 on arm

[Sagar Behere]

Hello,

I patched the vanilla linux-3.8 kernel sources with 
ipipe-core-3.8-arm-1.patch. The patch was applied cleanly, but while 
compiling the kernel, I get two problems

Problem 1: This is the same as

Any ideas how to fix these issues? I'll be running this kernel on the 
gumstix overo, if that matters..

Thanks and regards,

Please use xenomai git current head instead of xenomai 2.6.2.1 release. 
Xenomai 2.6.2.1 only supports I-pipe patches up to Linux 3.5 on ARM.
(in general, the latest I-pipe patch supported by a Xenomai version is 
the one it ships with).

Oh! I did not know that.

I now did: git clone git://git.xenomai.org/xenomai-head.git

and everything compiled properly in the subsequent steps.
