Hi All,
I am porting some code which uses Cython and Numpy from Ubuntu to OS
X, and have run into some problems getting the Cython compilation
process working. I am using distutils with the following in my
setup.py file:
> from distutils.core import setup
> from distutils.extension import Extension
> from Cython.Distutils import build_ext
>
> setup(
> cmdclass = {'build_ext': build_ext},
> ext_modules = [Extension("neuralRoutines", ["neuralRoutines.pyx"])]
> )
neuralRoutines.pyx imports and cimports numpy, amongst other things. I
don't think the problem lies in there because it runs fine as it is
under Ubuntu.
When I run "python setup.py build_ext --inplace" I get the following
error messages:
> Yarletts-Computer:scorelineModels yarlett$ python setup.py build_ext
> --inplace
> running build_ext

It looks like arrayobject.h is not being found, so do I need to modify
my setup.py file somehow? I'm afraid I'm not sure how to do this, so
any help would be greatly appreciated.
When I search for arrayobject.h it can be found in the following
places, amongst others, on my system:
> /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-
> packages/numpy/core/include/numpy/arrayobject.h
> /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-
> packages/numpy-1.3.0.dev6308-py2.5-macosx-10.3-i386.egg/numpy/core/
> include/numpy/arrayobject.h

Many thanks,
Dan.
