Ok, I found the solution:
I’ve installed xcode 3.2 on another partition and copied it’s /Developer/Extras/CoreAudio/AudioUnits/
then I replaced my AudioUnits directory (Xcode 4.2.1) with the previous one. (ain’t that ugly or what…)
So now I have a few questions in mind:
- Why should anybody compile an Audio Unit with SDK 10.7? (it won’t be backward compatible).
- Isn’t any way to do this mapping within Xcode? if it has the option to compile with 10.6 then it should automatically supply the corresponding CoreAudio libraries, right?
(Edit) 3. Do you think an Audio Unit should be backward compatible to more than the previous Osx version?
