Thomas, All,
On 2016-01-25 00:07 +0100, Thomas Petazzoni spake thusly:
> gauche does not build on sparc64, it fails with:
>
> No rule to make target 'sparc_mach_dep.lo', needed by 'libgc.la'
>
> On Sparc, it first fails with the usual "membar" assembler issue which
> comes from gauche's internal version of libatomic_ops. However, even
> passing -DAO_NO_SPARC_V9 like we do for libatomic_ops is not
> sufficient, as we fall into the same build problem as on sparc64.
>
> Consequently, this commit disables the gauche package on the sparc and
> sparc64 architectures.
>
> Since it uses its own libatomic_ops copy, and libatomic_ops does not
> have any dependency on atomic built-ins, we also remove the
> BR2_ARCH_HAS_ATOMICS dependency. It was originally added to prevent
> gauche from being built on sparc, but this will no longer happen.
