[Numpy-discussion] site.cfg doesnt function?

[Nadav Horesh]

I checked out numpy from svn few hours ago, and created a site.cfg following site.cfg.example. During the build process I am getting an warning that unoptimized lapack in being used.

Machine: dual core amd64 running gentoo linux.
Relevant packages: python 2.5.1, blas-atlas-3.8.0, lapack-atlas-3.8.0

# site.cfg

[ALL]
library_dirs = /usr/lib64/lapack/atlas:/usr/lib64/blas/threaded-atlas:/usr/lib
include_dirs = /usr/include/atlas:/usr/include
[blas_opt]
library_dirs = /usr/lib64/blas/threaded-atlas:/usr/lib64
libraries = blas, cblas, atlas
[lapack_opt]
library_dirs = /usr/lib64/lapack/atlas:/usr/lib64
libraries = lapack, blas, cblas, atlas
[fftw]
libraries = fftw3




I added the following print lines in system_info class:

   def __init__ (self,
                  default_lib_dirs=default_lib_dirs,
                  default_include_dirs=default_include_dirs,
                  verbosity = 1,
                  ):
        print '\n\n====================================='
        print '    class: ',self.__class__
        print '     libs: ', default_lib_dirs
        print ' includes: ', default_include_dirs
        print '=====================================\n\n'

-------------------------------------------

* Why /usr/local/lib and /usr/local/include are there although they are not in site.cfg?
* Why lapack library was not found?
* site.cfg.example is located in ~/numpy but the UserWarning indicates numpy/distutils/site.cfg. I copied site.cfg also to ~/numpy/numpy/distutils but it did not help.
