[Numpy-discussion] RFC: add a install_clib numpy.distutils command to install pure C libraries

[David Cournapeau]

Hi,

    I have finally spent some time so that we can install pure C
libraries using numpy.distutils. With this, one could imagine having a C
library for fft, special functions in numpy or scipy, so that the
library could be reused in another package at the C level. If someone
knowledgeable about numpy.distutils would like to review this branch, I
would be grateful:

The branch uses this functionality for npy_math, so that we can do:

# get_npymath_info is in numpy.distutils.misc_util, and its output is
compatible with system_info
config.add_library("foo", sources=['foo.c'], extra_info=get_npymath_info())

The code to add an installable library is generic, but there is no code
to get the build info for external packages (except for npy_math). I did
not find an obvious way to do this generically,

thanks,

David
