I think PyObject *PyInit_myextention(void) should be PyMODINIT_FUNC PyInit_myextention(void) on https://docs.python.org/3/howto/cporting.html#module-initialization-and-state It didn't work for me until I replaced this with a message in the about 'undefined PyInit_myextention'. However, when I used nm to inspect the .so object file, I fond the PyInit_myextention (but probably with the wrong return type). Moreover, whenever I would remove the same .so importing resulted in a different error complaining that the module does not exist (strongly suggesting that I did not mix up .so files). Good luck!

The exact error was: ImportError: dynamic module does not define init function (PyInit_myextension)

https://docs.python.org/3/extending/extending.html#the-module-s-method-table-and-initialization-function documents what Herbert discovered wrong in the porting docs.

And in case my comment wasn't obvious, Herbert is right about the error in the docs.
