Finally I used following setup.py
from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext
import os
import numpy as np
ext_modules=[
Extension("lapack",
["lapack.pyx"],
libraries=['lapack', 'cblas'],
extra_link_args = ['-Wl,-framework', '-Wl,Accelerate'],
extra_compile_args =
['-faltivec','-I/System/Library/Frameworks/vecLib.framework/Headers'],
define_macros = [('NO_ATLAS_INFO', 3)],
include_dirs=[np.get_include()]),
Extension("testlapack",
["testlapack.pyx"],
include_dirs=[np.get_include()]),
]
setup(
name = 'LAPACK wrapping demo',
cmdclass = {'build_ext': build_ext},
ext_modules = ext_modules,
)
I build it using /usr/bin/python, lapack.so and testlapack.so are used following
libs, but it still don't work.
otool -L lapack.so
lapack.so:
/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/
vecLib.framework/Versions/A/libLAPACK.dylib (compatibility version
1.0.0,
current version 219.0.0)
/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/
vecLib.framework/Versions/A/libBLAS.dylib (compatibility version 1.0.0,
current version 219.0.0)
/System/Library/Frameworks/Accelerate.framework/Versions/A/Accelerate
(compatibility version 1.0.0, current version 4.0.0)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 246.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 125.0.0)
otool -L testlapack.so
testlapack.so:
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0,
current version 246.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, c
urrent version 125.0.0)
But it still doesn't work (
