I have recently re-compiled my PDE as a Universal Binary and it works well in most settings; however, I have just found out that it will not run on 10.2.8.
The Console log shows that the '/usr/lib/libmx.A.dylib' does not exist.
I have found some threads on the Xcode Users list that explain that targets built with GCC 4 will not run on Mac OS 10.2... is this true?

Yes, C++ code compiled with gcc 4 requires 10.3.9 or later. C and Obj-C code should be okay.

According to the 'Universal Binary Programming Guidelines' Xcode uses GCC 4.0 for targeting Intel-based Macs.

Is it possible to build a Universal Binary PDE that will run on 10.2, 10.3, 10.4, and Intel?

Yes, you just have to use gcc 3 for the PowerPC build.
