Hello,
I am trying to get a compiled module to work with Python3. The code I
am compiling was originally intended to be used in a Python 2.*
environment, but I updated all the Python 2.* elements and the swig
commands used by the setup.py script. I got the library to
successfully compile, but I am getting the following errors on import
(below). I am not sure how to trouble shoot this problem, and the
fact that only one symbol (_PyCObject_FromVoidPtr) is missing is
disconcerting. I Googled some, but the symbol mentioned only showed
up in a few posts, where linking was an issue. I have also gone
through the setup.py script and explicitly defined all the library
paths.
My questions:
- Has anyone ever ported Python 2* modules/libs to Python 3 that rely
on swig, and are there some changes in the C-API/swig I need to be
looking for to make this port successful?
- Does anyone have any advice/insght about how I can troubleshoot,
diagnose, and resolve this issue?
Thanks in advance,
-- Adam
