Re: [Xen-devel] problems compiling xen on a crusoe

[Keir Fraser <Keir.Fraser@xxxxxxxxxxxx>]

Please try adding '-nopie' to the 'CFLAGS := ...' in
xen/arch/x86/Rules.mk: 
CFLAGS  := -nopie -nostdinc -fno-builtin -fno-common -fno-strict-aliasing

If that doesn't help then also try adding '-fno-stack-protector' and
'-f-nostack-protector-all'. 

Let me know if this works out and I'll add the required options to the
the repository (may not be because non-PIE/SSP GCCs may barf on the
above command-line options).
