I'm running 64-bit Ubuntu and want to compile a 32-bit binary that links with BLAS and LAPACK. It seems like the Ubuntu Natty 64-bit BLAS and LAPACK dev libs come in 64-bit only. Is there an easy way to install the 32-bit versions of these concurrently with the 64-bit versions? Ideally the linker should automatically link to the right one, depending on whether the object files I'm trying to link to are 32-bit or 64-bit?
