Comment (by vbraun):
System ATLAS is (at least on Fedora) libatlas.so.3 and we install
libatlas.so.2. Since I rebuilt various packages mixing system atlas (using
SAGE_ATLAS_LIB) and self-compiled atlas, I ended up with a mix of symbols.
I've changed our versioning to use .3 as well. Upstream doesn't version
the library but since it is ATLAS 3.x most distributors will probably opt
for .3.
I agree that there is no point in 3DNow on SSE-enabled processors. Its not
used anywhere now.
I think that was the problem with 32-bit, too. But I'm still running
tests. Will re-enable "fast" threads on 32-bit if it works...
I've changed the threads option to colon
{{{
SAGE_ATLAS_ARCH=threads:2,static,fast
}}}
and added the optional "static" to also install static libraries (though
built with -fPIC, really only useful for debugging)
Finally, I'm also installing upstream's new ATLAS shared library
(libsatlas.so / libtatlas.so). Eventually we'll want to switch Sage over
to those, so we might just as well install them already.
