ILCPP on Apple Silicon fails with GameAssembly.dylib (No such file or directory)

Unity Engine

Trying to build my project created on windows on my M1 Mac Mini with Xcode 12.4, Unity 2020.3.0f1, running on Big Sur 11.2

I’m not sure if this is already a known issue but I could not find anything on it so I’m asking here. When generating the Xcode project and building with automatic signing or building without generating the Xcode project the build fails with

fatal error fatal error: lipo: can’t open input file: /Users/nevercode/Library/Developer/Xcode/DerivedData/Mac-aweffplarrgmgaaekhyoznoerxaf/Build/Intermediates.noindex/Mac.build/Debug/x64/GameAssembly.dylib (No such file or directory)

And when building from Unity without generating the Xcode project it fails with
Exception

…(this goes on)

I thought this was an issue with the arch being only arm64 since I saw some could not find symbols for x86_64 messages so I tried opening up Xcode with Rosetta but that did nothing. I’m fresh out of ideas.

On Mono, I was able to build successfully and am figuring out codesigning

2

Can you post the full editor log? The error is somewhere inside “this goes on”.

3

It ends with a message saying the logs were truncated so I didn’t see anything but those repeated .o file references. Is there a log file somewhere with the full logs?

4

Yeah, see Unity - Manual: Log files

This is what was at the end

Is Platform.FMOD a native plugin you have in your project? Perhaps it doesn’t support Apple silicon?

The root cause of the issue was this. Applied the workaround and was able to build successfully.

Thanks for the help!
