Sean,
In the latest release, there is a include for wx/setup.h (which does not exist for me) in platform.h on line 154.
I believe this is for including if you are compiling in UNIX or perhaps Linux. I commented out the line that bombed and the code compiles fine in windows. Do you have a copy of wx/setup.h (It should be in the wxWidgets/include library)?
Kinda weird. Is there something I am missing in my wxWidgets?
