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
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
(assuming libblas.so is the name of the library) ?
