Comment(by fbissey):
So I have had a look at the ATLAS spkg and the ATLAS installation
instructions[[BR]]
[http://math-atlas.sourceforge.net/atlas_install/atlas_install.html][[BR]]
Of Particular interest are the section on lapack.
So you can build lapack first. I always thought that you needed to build a
blas
first as lapack uses blas routines. Well that's what it says on lapack's
homepage.[http://www.netlib.org/lapack/][[BR]]
So the ATLAS spkg does textbook application of section 3, and once we are
done
we need to replace the old liblapck.a with the one provided by ATLAS which
basically
replace a few routines with optimized one. That explain why ATLAS depends
on lapack,
and possibly the whole chain blas->lapack->atlas.
I think it would be better to follow the scenario played out in section 8,
but I have a feeling it relies on there being a blas somewhere in the
system. There are ways
I am sure. In gentoo we build lapack-atlas afterwards - it is somewhat
involved.
The main problem in this kind of scenario is technically you may build
lapack with
2 different libf77blas. I am not sure what atlas does to ensure that
doesn't lead
to serious troubles.
