I cannot rebuild my kgcc64 on sparc64 at all :-(

[Comment 6 Alex Buell 2010-10-19 21:43:11 UTC]

Note that however, it can still build linux kernels reliably.

Please attach the config.log in question too.

Could you attach the config.log from libgomp subdir? I don't think that's the one currently posted...

Is this the one you're after? Looks like it couldn't find a file it needed.

Right, that's the one. Assigning to maintainers now.

[Comment 12 SpanKY 2010-11-19 06:57:17 UTC]

kgcc64 shouldnt be attempting to build any target library including, but not limited to, libgomp

please try this patch and see if it fixes things for you

Great news; patch fixes the kgcc64 compile problem on SPARC architectures, thanks.
I tested patched, build just fine, put back the unpatched versin, build failed. 
 
Now if I could get i686 crosscompilers sorted on SPARC, I'd be set, but that's a separate bug report.

committed then ... thanks for testing
