In the short term, you should try adding
-DMISSING_mm_cvtsd_f64
to the compile flags in the .arch file that you're using, which ought to
fix things. So that we can have a better idea of what's going on with
your case, could you let us know what version of gcc you're using, and
the exact model of processor (cat /proc/cpuinfo)?
Best,
Peter
