BLAS/LAPACK implementations



Hello,

Some time ago, the netlib and ATLAS implementations of BLAS and LAPACK
were ABI-compatible, and used alternatives symlinks to access their
different libraries with the same ABI.

I don't know when it happened, but at some point they diverged, and now
the netlib packages have libblas-3gf.so and liblapackgf-3.so, and ATLAS
has libblas-3.so and liblapack-3.so.

I know that ATLAS has its own API as well, but it was nice back in the
day to be able to build to the netlib API, and then swap them back at
forth at runtime using update-alternatives.

Are they no longer ABI-compatible?  Is it possible to get back to the
old state of things?
