Solved. The necessary functions are in CAAudioChannelLayoutObject.cpp. Pardon my ignorance.

Hi,
I need to implement a surround panning plug-in as an Audio Unit. Even though there doesn't seem to be any documentation on it, I figured that AUPannerBase would be the place to start. However, I can't even get a simple file to compile. After adding all the necessary frameworks and files, ld still cannot find some symbols:
"CAAudioChannelLayout::CAAudioChannelLayout()", referenced from:
AUPannerBase::AUPannerBase(ComponentInstanceRecord*)in AUPannerBase.o
"CAAudioChannelLayout::~CAAudioChannelLayout()", referenced from:
AUPannerBase::~AUPannerBase()in AUPannerBase.o
"CAAudioChannelLayout::operator=(AudioChannelLayout const*)", referenced from:
AUPannerBase::RemoveAudioChannelLayout(unsigned int, unsigned int)in AUPannerBase.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
And indeed: the constructor and overloaded operator= of CAAudioChannelLayout are defined in CAAudioChannelLayout.h, but are nowhere implemented in CAAudioChannelLayout.cpp
Am I missing something here?
Thanks,
Alex
