You might need to reinstall QT.

Hi all,
I'm working with the Audio Units Tutorial found here
http://developer.apple.com/audio/audiounits.html
I keep getting an error 'struct HostCallbackInfo' has no member named
'transportStateProc' when trying to build MyVolumeUnit.cpp
The build results are thus:
Building target "MyVolumeUnit" with build style "Development"
(optimization:level '0', debug-symbols:on) — (2 errors)
Compiling MyVolumeUnit.cpp (2 errors)

I found this page
(http://lists.apple.com/archives/coreaudio-api/2004/Sep/msg00128.html)
about the same sort of error but it was of no help. Neither deleting
AUPropertiesPostPantherAdditions.h nor deleting and reinstalling
Quicktime helped. But I am using Quicktime 7 though I don't think
that should make a difference. Can anybody shed any light on this?
Thanks a bunch,
Michael
