[Pythonmac-SIG] C++ ABI 1002/102 incompatibility with wxPython

Tue Feb 8 12:55:14 CET 2011

I'm still stuck on this.  Has anyone got any suggestions to help solve
the ABI compatibility issue with wx ??

I think it's something to do with building on 10.6 Intel, and trying to
run on 10.4 PPC.  It seems to work ok when run on 10.4 Intel.

My 10.4 Intel box has Apple python 2.3.1 (/usr/bin/python) and wx
2.5.3.1 installed, and python.org 2.5.1 (/usr/local/bin/python) and wx
2.8 (i think).

My 10.4 PPC box has Apple python 2.3.1 (/usr/bin/python) and wx 2.5.3.1
installed.

It really shouldn't matter what I have installed if py2app is truly
packaging up all libraries and dependencies (assuming they are universal
builds).

Thanks, Brendan.
