Running code from source that includes extension modules

[Michael Schwarz]

Hi

I've just started looking into distutils because I need to write an
extension module in C (for performance reasons) and distutils seems to be
the most straight-forward way.

I've had success building a C file into a Python extension module using
"python setup.py build" but I am wondering what the recommended way for
using that module during development is. While writing Python code I'm used
to just run the code from the source directory. But the built extension
module's .so of course does not just end up on sys.path magically.

So how do I run my code so it will find the built extension module? Do I
pass the output directory on the command line manually or is there some
other solution? I would like to still be able to run the code from the
source directory as I'm using PyCharm to edit and debug the code.

Many thanks!

Michael
