I am currently trying to create a C extension on Windows. Errors, apparently, are related to the fact that they do not detect "standard" characters in the python27.dll file. How to resolve these missing characters? Do I need to somehow tell the compiler where to find python27.dll or something is wrong with my python27.lib?
My setup is this:
- 64-bit version of Windows 7
- Python 2.7.4
- Numpy 1.7
- Swig 2.0.9
- Visual studio 9.0
I found this link, which seems to be related to the problem, but with versions of things that I don't use: http://bugs.python.org/issue15772
I run python setup.py build_ext --inplaceto create an extension.
The setup.py file is as follows:
try:
numpy_include = numpy.get_include()
except AttributeError:
numpy_include = numpy.get_numpy_include()
fmm3d_module = Extension('_fmm3d', sources=['fmm3d.i', 'fmm3d.c'],
include_dirs = [numpy_include])
Everything compiles fine, and then the following communication command starts:
