Hi,
When I remove the -O3 or change it to -O0, -O1, or -O2, I get this error, but not when I leave it at -O3.
<x-tad-smaller>
ld: audio_device.o illegal reference to symbol: _AudioDeviceSetProperty defined in indirectly referenced dynamic library /System/Library/Frameworks/CoreAudio.framework/Versions/A/CoreAudio
</x-tad-smaller>
Any ideas why a compiler optimization will cause ld to have this type of difficulty?
Thanks,
Rob
