well, options for C don't have the same syntax as Fortran, so I used
'-mcpu=v9 -lsunperf' and got :

ImportError: ld.so.1: python: fatal: relocation error: file
/Produits/sun/forte/7/SUNWspro/lib/libsunperf.so.4: symbol __f95_sign:
referenced symbol not found

but then, I realized I was using the default libsunperf (v8). As I'm
building on sparc III, I want v9b optimizations, so I did :


and got :

ld: fatal: file /Produits/sun/forte/7/SUNWspro/lib/v9b/libsunperf.so:
wrong ELF class: ELFCLASS64

but I'm building 64 bits code, am I not? I added the -m64 option and got :

#error "LONG_BIT definition appears wrong for platform (bad gcc/glibc

Damn, it looks like my python was compiled in 32 bits. Well, if I have
to keep to 32 bits, so be it. Going back a few lines up, I have an
__f95_sign symbol not found (removing -mcpu=v9 doesn't change anything).
