Building AUv2 fails

[ghost]

This happened with the IPlugInstrument example out of the box. While there are no problems building the standalone app and the vst3 version, the AudioUnit 2 version seems to fail.

I did some digging around and this path in the build settings under other rez flags doesn't seem to exist on my computer: /System/Library/Frameworks/CoreServices.framework/Frameworks/CarbonCore.framework/Versions/A/Headers The headers folder at the end doesn't, to be specific.

This the build error message:

failed to find AUComponent/AUComponent.r /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/AudioUnit.framework/Headers/AudioUnit.r:18: ### Rez - noErr (0) during open of "AUComponent.r". Fatal Error! /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/AudioUnit.framework/Headers/AudioUnit.r:18: ### Rez - Fatal Error, can't recover. AUComponent.r: ### Rez - Since errors occurred, /Users/vm/Library/Developer/Xcode/DerivedData/IPlugInstrument-bnkwvakgncaduvfychxdutzjvqwa/Build/Intermediates.noindex/IPlugInstrument-macOS.build/Debug/AU.build/ResourceManagerResources/Objects/IPlugAU.rsrc's resource fork was not completely updated. Command Rez failed with a nonzero exit code

Ultimately changing the include path here https://github.com/iPlug2/iPlug2/blob/3add4564d92638c6a160bcab7910d6c009e85e13/IPlug/AUv2/IPlugAU.r#L12

to #include <AudioUnit.r> fixed the build process for me.

Thanks, this is with xcode 11 right?

Oh I forgot to mention that. Yes I'm on Mojave 10.14.6 and xcode 11

could you try pulling from master and see if efee29009ed9687fb36a48c41c4bc45d8bac6f30 fixes it, seems to still work on xcode 10 with path changed

[ghost]

Yes, this fixed it for me. Thanks for looking into this
