It is weird, but there is a rationale to the weirdness :) It is basically imposible to build a rpm for ATLAS, because every build produces a different binary. Because there is no atlas binary, I cannot depend on it, and so numpy/scipy depends on netlib blas/lapack. For people who still want to use atlas, I provided a source rpm that people can use if they want. Instead of building atlas the "normal" way, it builds full blas and lapack, which are drop-in replacements for netlib blas/lapack, while using atlas optimization. It means that atlas specific optimizations in numpy/scipy won't be used, but well, that's better than nothing, and is certainly faster for many operations than netlib. It works pretty well on opensuse 10, fedora 6, 7, and 8, as well as RHEL 5, both 32 and 64 bits so I would be surprised if there was a problem specific to centos related to atlas. All this is put on the wiki. I am open to suggestion for better instructions: http://www.scipy.org/Installing_SciPy/Linux cheers, David _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
