Hello,
I am trying to create an audio unit using the latest Core Audio Utility Classes as downloaded from the Mac Developer Library:
https://developer.apple.com/library/mac/#samplecode/CoreAudioUtilityClasses/
Compilation fails with a multiple inheritance problem in AUMIDIEffectBase.cpp:
CoreAudio/AudioUnits/AUPublic/OtherBases/AUMIDIEffectBase.cpp:160:18:
Member 'MIDIEvent' found in multiple base classes of different types
CoreAudio/AudioUnits/AUPublic/AUBase/AUBase.h:704:19:
Member found by ambiguous name lookup
CoreAudio/AudioUnits/AUPublic/OtherBases/AUMIDIBase.h:71:19:
Member found by ambiguous name lookup
I solved this resolving the ambiguity by changing the line
result = This->MIDIEvent(inStatus, inData1, inData2, inOffsetSampleFrame);
to
result = This->AUMIDIBase::MIDIEvent(inStatus, inData1, inData2, inOffsetSampleFrame);
(which seemed to most useful of the two, as the MIDIEvent implementation just returns kAudio_UnimplementedError).
Can someone confirmed that this fix is correct?
thanks, Fokke |
