[Pythonmac-SIG] Universal wxPython app fails when run on second (PPC) machine

[Erik Westra]

Hello, pythonmac folks.

Thanks to all the hard work you guys have been doing getting Python  
to run on Intel, I have a wxPython application which runs beatifully  
on my MacBook Pro.  I'm using the Framework build of Python 2.4.3  
under OSX 10.4.6, with the "pre-release" universal wxPython version  
2.6.3.2rc2.  This works perfectly on the Intel machine, but I now  
have to create a standalone version of my system which also runs on  
PPC-based Macs.

I downloaded and installed Bob Ippolito's py2app, version 0.2.5 from  
http://pythonmac.org/packages/py24-fat.  To my pleasant surprise it  
worked first time, successfully building a standalone version of the  
application which runs on the Intel machine just fine.  But when I  
try to copy the app and run it on a second (PPC-based) machine, the  
application crashes with the following error message:

I'm not sure if this is because the application is running under PPC,  
or if the application is trying to load /usr/local/lib/wxPython- 
ansi-2.6.3.2rc2/lib/libwx_macd-2.6.0.dylib, which just happens to be  
installed on the MacBook Pro but not on the PPC machine.

Any suggestions for how to get this going?  Do I need a later version  
of py2app, perhaps?  Or can I add something to my setup.py script to  
force this library to be included in the bundled application?

Thanks,

  - Erik.
