Python 3 Support

Installation

I reinstalled Panda from this http://www.panda3d.org/download.php?platform=macosx&version=devel&sdk “Panda3D-SDK-1.10.0-2acde88-MacOSX10.6.dmg” and I got this result:

I did a vanilla install from the dmg. I only had a couple of minutes this morning so my debug time is limited.

I did notice this other posting: [url]Panda3D OSX issues Python linking]. That there was reference to a bug in GCC:

In [url]Installing on Ubunutu 7.10] there is reference to different version of Python:

Did I grab the wrong version? I can swap out the Python version if need be. When I tried compiling Panda, I got bogged down with the third party apps. Is it worth getting that pipeline working to have the latest Panda? I’m just starting out with the engine, so I don’t need all the bells and whistles. I have a lot to learn as it is! I’m not sure if I mentioned this, but I’m running a Mac with OS 10.12.2.

As a side note, should I code my Python code differently to support Cython? I was planning on using CTypes within Python. Good idea or not worth the effort?

Thanks for the input!
