Looking at Python modules and at code in the “lib-dnyload” directory in the Python framework, I noticed whenever code is creating some kind of GUI or graphic it imports a non-Python file with a .so extension. And there are tons .so files in “lib-dnyload”.
From googling things I found that these files are called shared objects and are written in C or C++. I have a Mac and I use GCC. How do I make shared object files that are accessible via Python? Mainly just how to make shared objects with GCC using Mac OS X.
In my opinion the easiest way is to use Cython. Cython will generate some C code for you, compile it to make a “.so” library that you can load from python. This is easy and painless. I suggest you to follow the tutorial and you should have a so library pretty soon.
If you want to know all the details behind C extensions of python, you should dive in the Python documentation about C extensions.
