There won't be a v5 coming because I can't overcome the circular dependency.
I think, actually, that we should just drop the clapack package. It's dead (the
lapack maintainers no longer generate clapack based on new lapack releases,
probably because f2c is unmaintained).
I remember Romain and I were banging our heads against lapack, clapack and
openblas a couple of years ago on a Buildroot developer meeting - I believe it
was in the context of numpy at the time. I don't remember exactly what the
conclusion was, but IIRC there was no good solution at the time either.
Well, in the end I went ahead and sent a v5 which removes clapack and
re-introduces the choice for BLAS provider. The "choice" for LAPACK provider is
automatic though (it's just yes or no anyway).
Gwenhael, what do you think?
Regards,
Arnout
