I had successfully been working on a system with Xcode 12.2 beta, Xcode 11.3 and Xcode 11.7 installed in parallel, building a CMake-based universal binary plugin with Xcode 12.2 beta. Today I accidentally installed Xcode 12.1 from the App Store, which replaced my 11.7 installation. After doing so I get errors like
failed to find AudioUnit/AudioUnit.r Path/To/JUCE/modules/juce_audio_plugin_client/juce_audio_plugin_client_AU.r:27: ### Rez - noErr (0) during open of "AudioUnit.r".
I initially assumed that something wasn’t working with the new Xcode, so I switched back to XC 12.2 beta with
xcode-select, but no success. I saw a thread from earlier this year that solved a Rez error in CLion, however I’m quite a bit behind that commit.
Can anyone explain what’s happening here? I have to admit that I have not heard of Rez until today, so I’m a bit unsure where I should even start looking for solutions to this issue?
