[Numpy-discussion] numpy.distutils, lapack, and cython

[Nathaniel Smith]

Hi all,

I've gotten a pull request for scikits-sparse to switch it to using
numpy.distutils:
  https://github.com/njsmith/scikits-sparse/pull/2

Overall this seems fair enough, finding libraries is a pain and
numpy.distutils has that knowledge.

1) What's the proper way to find lapack using numpy.distutils? The
patch tries lapack_mkl_info and lapack_info, but this is 2 of the 6
variants that my numpy.distutils.system_info contains. Really what I
probably want is a way to ask numpy how it was built (including any
custom paths the user used) and to default to doing the same? Is that
possible?

2) Is there a better way to build Cython files than this weird
monkey-patching thing they propose? (It's still better than the horror
that setuptools/distribute require, but I guess I have higher
expectations...)

3) Can I use 2to3 along with numpy.distutils?
