I found some issues with JuceAudioDemoAU example on PPC.
Working with the latest Juce version I tried to compile the example (changing first juce.xcconfig to 10.3 and later compatibility) and I got the error:
It shows in CAAtomicStack.h in
#include < libkern/OSAtomic.h>
So the first question is how to force the XCode to compile it for 10.3 and later OSX?
Next I switched the juce.xcconfig to OSX 10.4 and later and I compiled the example successfully. The files is signed as Universal Binary but it works only on Intel Macs. On PPC machines it seems to be unrecognizable by any host or auval command line tool (auval -a)
Any hint why?
