How to build a Python C Extension so I can import it from a module
Just change
Extension('c_extension', ...)to
Extension('foo.bar.c_extension', ...)You will need __init__.py files in each of the foo and bar directories, as usual. To have these packaged with the module in your setup.py, you need to add
packages = ['foo', 'foo.bar'],to your setup() call, and you will need the directory structure
setup.pyfoo/ __init__.py bar/ __init__.pyin your source directory.
