Unity won't build for Android using IL2CPP on Macbook Pro using Big Sur

Unity Engine
1

Unity version: 2018.4.30f1
OS: Big Sur 11.1

Build settings
Scripting Backend: IL2CPP
API Compatibility Level: .NET 2.0 Subset
Target Architectures: ARMv7 + ARM64

I get build errors on all Macbooks running Big Sur 11.1. I have created an empty project and I still get this error when building. It has been working perfectly until updating to Unity 2018.4.30f1 (but downgrade won’t work anymore either).

Can any of you help or try to recreate the build with this setup to see if it fails for you as well? I think it might be a Unity bug.

Can you provide details about the error message?

Hey Josh, thanks for your comment. I am getting these two errors:

Thanks for the details. I’m unsure why this happens, and the error message from the clang compiler in the Android NDK is not providing any information. When this happens, can you run the clang compilation that fails directly from the command line?

Be sure to try this with the Unity Editor still open - that will keep all of the necessary temporary files in the right state. Hopefully this will give us an error from clang that we can make sense of.
