I'm using the basic "hello world" demo straight out of the Cython documentation. It works fine unless I try to import py2app in the same setup.py file:
import py2app
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("helloworld", ["helloworld.pyx"])]
)
Py2app itself works fine as long as I pre-generate the .c files for my Cython modules. But if I haven't, then build_ext fails with:
running build_ext
gcc-4.2 not found, using clang instead
building 'helloworld' extension
clang -fno-strict-aliasing -fno-common -dynamic -arch i386 -arch x86_64 -g -O2 -DNDEBUG -g -O3 -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c helloworld.c -o build/temp.macosx-10.6-intel-2.7/helloworld.o
clang: error: no such file or directory: 'helloworld.c'
clang: error: no input files
error: command 'clang' failed with exit status 1
If I comment out import py2app in setup.py, build_ext works fine and I get the missing intermediate step in my compilation:
...
gcc-4.2 not found, using clang instead
cythoning helloworld/helloworld.pyx to helloworld/helloworld.c
building 'helloworld' extension
...
So what is it about py2app that breaks Cython? And what can I do about it? I'd like to have just one setup.py for my project, obviously.
I have Cython 0.18 and py2app 0.7.2, installed from PyPI. I'm using Mac OS X 10.8 with the python.org Python 2.7.3, not Apple's build.
