SuSE 10.0 comes with gcc-fortran
Name : gcc-fortran Relocations: You're right. But the executable is called 'gfortran'. I mixed that up.
I have already build blas and lapack libraries using g77 according to the installation hints.
Can I use them or must I recompile blas and lapack with gfortran ? I'm not an expert on this subject, just sharing my experiences. If you're using ATLAS you don't need BLAS as far as I understood. I followed the instructions in
Nils Wagner wrote: the link I posted before. Compared to the compilation time of ATLAS, LAPACK builds almost instantaneously, so it doesn't hurt to rebuild LAPACK, I just don't know wether g77 built LAPACK works together with gfortran ATLAS. At least I know, that if you're using gfrotran all the time, everything works fine on SuSE 10.0.
Good luck, Christian

I followed your advice and rebuilt blas and lapack using gfortran. Compilation of ATLAS seems to work. Also I have build a complete lapack http://math-atlas.sourceforge.net/errata.html#completelp
I am on SuSE 10.0 x86_64 GNU/Linux
However
python setup.py build failed

I can't say more than that I followed exactly the instructions here: http://pong.tamu.edu/tiki/tiki-view_blog_post.php?blogId=6&postId=97 (the full LAPACK issue is covered there, too) and it worked. Christian
