Do I understand correctly that you want to compiler numpy/scipy with
gcc, using sunperf ? I am not familiar with non gnu devtools under
solaris, so I don't know if sunperf libraries are supposed to work with
gcc ?
My main guess, though, would be that sunperf requires more than just
-lblas option to link; generally, you need some other link flags. Since
the default error message of the linker is non explanatory, we need more
info. What does nm
/local/cat2/apps-archive/SUNWspro-12/prod/lib/libblas.so returns
(assuming libblas.so is the name of the library) ?
cheers,
David
