py26-numpy with veclib

[Robin-62]

Hi,

Is it possible to build py26-numpy against veclib with macports?

I had assumed that specifying +no_atlas variant would fall back to
using veclib (from reading tickets it looks like thats what it did
before) but instead it seems to use no accelerated library. This is
the result of numpy.show_config() when built with +no_atlas:

Python 2.6.3 (r263:75183, Oct 21 2009, 13:12:29)
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy
>>> 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:

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

blas_mkl_info:
  NOT AVAILABLE

atlas_blas_info:

If linked against veclib the output should look like 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)]

Cheers

My config shows this:

Python 2.6.3 (r263:75183, Oct 13 2009, 08:46:50)

     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)]

Note that I am on x86_64, so that looks a bit strange.

It does for me:

This is actually for the default variants…

Then, however, the question is why it used -faltivec instead of -msse3  
or such on my Mac Pro (x86_64)...

Ah, thanks. I wonder why it doesn't for me. I am using up to date
macports with snow leopard. For me the default variants leads to being
built with atlas. If I specify no_atlas variant then I get the no
external blas shown earlier. I wonder if something has changed
recently to stop building against veclib.

Shall I open a ticket?

Me too

Actually, I don't have ATLAS installed, so that's the difference...

I don't think so - I can't build +no_atlas with atlas installed - if
its there it gets used regardless of the variant :
http://trac.macports.org/ticket/22201

So when I build +no_atlas without atlas installed I get no external
blas (not veclib) http://trac.macports.org/ticket/22200

I don't know what to do to get veclib...

Cheers

What do you get if you have no ATLAS around and do not specify any  
variant?

Do you have the latest XCode updates?

Atlas gets installed as a dependency if I don't specify any variant.

I have xcode 3.2, core: 1608

Hi Robin,

a) please file a ticket.

b) we are apparently talking about different versions of the Portfile,  
although nobody told MacPorts about it!

The following changes (and probably a few more) were made without  
changing the revision in the Portfile… I picked these latest two  
because they are the suspects for the problems you are seeing

------------------------------------------------------------------------
r59616 | jameskyle@... | 2009-10-18 00:56:16 +0200 (So, 18  
Okt 2009) | 2 lines
Changed paths:
    M /trunk/dports/python/py26-numpy/Portfile

Added proper deletion of default opts for no_gcc43 and no_atlas  
variants.

------------------------------------------------------------------------
r59608 | jameskyle@... | 2009-10-18 00:55:57 +0200 (So, 18  
Okt 2009) | 2 lines
Changed paths:
    M /trunk/dports/python/py26-numpy/Portfile

Added ATLAS, LAPACK, and BLAS build environment to point to macports  
libs.



c) Please file a ticket, unless already done.
