[Numpy-discussion] New Linux build problem

[Brian Granger]

Hi,

I am building numpy on a 32 bit Linux system (Scientific Linux).
Numpy used to build fine on this system, but as I have moved to the
new 1.0.3 versions, I have run into problems building.  Basically, I
get lots of things like:

undefined reference to `cblas_sdot'

and

undefined reference to `PyArg_ParseTuple'

Here are some highlight of the build process:

lapack_info:
  libraries lapack not found in
/home2/dechow/work/txp/txpython-0.2-linux/local/lib
  libraries lapack not found in /usr/local/lib
  FOUND:
    libraries = ['lapack']
    library_dirs = ['/usr/lib']
    language = f77

  FOUND:
    libraries = ['lapack', 'blas']
    library_dirs = ['/usr/lib']
    define_macros = [('NO_ATLAS_INFO', 1)]
    language = f77

And later:

Have there been recent changes to distutils that would cause these
undefined references to appear?

Thanks
