Cannot get Turbo Native Example to build on M1 Mac

[tmchale]

Description

I am trying to get a simple RN app to build accessing a Turbo Native ObjC++ module. I followed the example in the Turbo Native docs (https://reactnative.dev/docs/next/the-new-architecture/pillars-turbomodules). I did comment out fabric_enabled and flipper lines from the Podfile and that got rid of some warnings. But I still get this error and I do not know how to solve it:

The following build commands failed: CompileC /Users/MCHALTX1/Library/Developer/Xcode/DerivedData/adcConsoleApp-eudyfqiurftvwseixxuzruouwnqy/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/rtn-dcs.build/Objects-normal/arm64/RTNDcs.o /Users/MCHALTX1/testdev/reactProjs/MyProject/MyProject/node_modules/rtn-dcs/ios/RTNDcs.mm normal arm64 objective-c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'rtn-dcs' from project 'Pods') (1 failure)
