def get_cblas_libs(self, info):

Check whether we can link with CBLAS interface

This method will search through several combinations of libraries to check whether CBLAS is present:

  1. Libraries in info['libraries'], as is
  2. As 1. but also explicitly adding 'cblas' as a library
  3. As 1. but also explicitly adding 'blas' as a library
  4. Check only library 'cblas'
  5. Check only library 'blas'

Parameters

info : dict
system information dictionary for compilation and linking

Returns

libraries : list of str or None

a list of libraries that enables the use of CBLAS interface. Returns None if not found or a compilation error occurs.

Since 1.17 returns a list.
