Hi,

I tried to upgrade to xenomai 2.6.3 and compilation failed with :

linux-2.6.38.8/arch/x86/include/asm/xenomai/bits/pod.h: Assembler messages:
linux-2.6.38.8/arch/x86/include/asm/xenomai/bits/pod.h:305: Error: no

I am using kernel 2.6.38.8 with adeos-ipipe-2.6.38.8-x86-2.11-03.patch.
I used binutils-2.18.1 and gcc-4.3.2.
With a more recent toolchain, there is no compilation failure.
Is there a new minimal binutils/gcc version for xenomai 2.6.3 ?

Regards,

Jean-Baptiste
