Comment 1 Jakub Jelinek 2012-01-05 13:07:29 UTC
Guess go hasn't been ported to ARM yet, will need to %global build_go 0 for %{arm} then.

Comment 2 Jakub Jelinek 2012-01-06 08:15:43 UTC
Should be fixed in gcc-4.7.0-0.4.fc17.  Of course, even better would be if somebody spent the needed time and actually made go work on arm.

Comment 3 Dan Horák 2012-01-06 09:31:44 UTC
Same applies to s390(x) and ppc(64) I think, but after seeing some patches that add support for Alpha and MIPS to libgo it really shouldn't be hard to add support for our arches to libgo too.

s390 support

arm support

Comment 6 Dan Horák 2012-01-06 18:05:31 UTC
With syscall_linux-s390{,x}.go files libgo should be buildable (couldn't refresh the configure script due incompatible autoconf version on my machine). The ARM support is untested.
