py26-numpy 1.3.0 - doesn't build against veclib

Description

I would like to be able to build numpy against veclib/accelerate framework. I understand the default is to use atlas. When I specify the variant +no_atlas, I expected to use veclib instead, but instead no external BLAS is used.

numpy.show_config() for default variant:

In [4]: numpy.show_config()
atlas_threads_info:
   libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
   library_dirs = ['/opt/local/lib']
   language = f77
   include_dirs = ['/opt/local/include']

blas_opt_info:
   libraries = ['ptf77blas', 'ptcblas', 'atlas']
   library_dirs = ['/opt/local/lib']
   define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
   language = c
   include_dirs = ['/opt/local/include']

atlas_blas_threads_info:
   libraries = ['ptf77blas', 'ptcblas', 'atlas']
   library_dirs = ['/opt/local/lib']
   language = c
   include_dirs = ['/opt/local/include']

lapack_opt_info:
   libraries = ['lapack', 'ptf77blas', 'ptcblas', 'atlas']
   library_dirs = ['/opt/local/lib']
   define_macros = [('ATLAS_INFO', '"\\"3.8.3\\""')]
   language = f77
   include_dirs = ['/opt/local/include']

 NOT AVAILABLE

blas_mkl_info:

numpy.show_config() for +no_atlas variant:

In [2]: numpy.show_config()
blas_info:
    libraries = ['blas']
    library_dirs = ['/usr/lib']
    language = f77

lapack_info:
    libraries = ['lapack']
    library_dirs = ['/usr/lib']
    language = f77

atlas_threads_info:
  NOT AVAILABLE

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

atlas_blas_threads_info:
  NOT AVAILABLE

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

atlas_info:
  NOT AVAILABLE

lapack_mkl_info:
  NOT AVAILABLE

Expected numpy.show_config() for veclib:

>>> numpy.show_config()
lapack_opt_info:
   extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
   extra_compile_args = ['-faltivec']

   define_macros = [('NO_ATLAS_INFO', 3)]

blas_opt_info:
   extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
   extra_compile_args = ['-faltivec', '-I/System/Library/Frameworks/vecLib.framework/Headers']

   define_macros = [('NO_ATLAS_INFO', 3)]

Since ticket #22201 has been closed and marked a duplicate of this one, I thought it was worth noting that there is an additional problem. no_atlas variant has no effect if the atlas package is installed - numpy is linked against atlas regardless. This seemed to me a different issue than the above, hence the two different tickets.

I've just compiled py26-numpy +no_atlas +no_gcc43 and got this:

>>> numpy.show_config()
lapack_opt_info:
    extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
    extra_compile_args = ['-msse3']
    define_macros = [('NO_ATLAS_INFO', 3)]

blas_opt_info:
    extra_link_args = ['-Wl,-framework', '-Wl,Accelerate']
    extra_compile_args = ['-msse3', '-I/System/Library/Frameworks/vecLib.framework/Headers']
    define_macros = [('NO_ATLAS_INFO', 3)]

I'm going to uninstall and rebuild with +no_atlas, but leave the gcc43 and see how that goes. here's a full library link list too:

I will also check with +no_atlas variant with atlas installed next and report back.

Ok, I reproduced the issue and I think I've found the problem. Should have a fix soon.

comment:6 Changed 15 years ago by macports@…

I tried without atlas installed and with +no_atlas and +no_gcc43 (which I hadn't tried before) but still don't get the veclib linkage displayed as you do - it is as before (/usr/lib)... but I just checked, and those libraries in /usr/lib are symlinked to veclib framework - so maybe it is using veclib, just in a different way (numpy is displaying it differently). Not sure why this should be the case.
