Apple Silicon Support

[ThatGuySam]

With Apple possibly dropping the first Apple Silicon powered Mac as early as November what's the status of Audacity support for ARM-based Macs?

From what I've seen on other OSS projects they are basically ready to go and there's not much work needed to support it:
Handbrake Support
OBS Support
Blender Support (Was directly mentioned in the Apple presentation)

Additional context
I'm putting together a list of reported support for Apple Silicon so people can quickly see if their favorite apps are supported yet.

It is known that Audacity can be built on Raspberry Pi.
You are welcome to try building Audacity on an ARM-based Mac if you have access to one - let us know how you get on.

That's good news. I usually work in Node JS environments but I can try doing a build.

Are there any recommended resources/wiki articles for correctly running builds?

I've got the build environment setup after some troubleshooting and I'm trying to get Xcode's Universal Build working (Hopefully, that's an appropriate approach)

I can, however, confirm that the public 2.4.2 build works out of the box (because of Rosetta 2) on macOS Big Sur running on physical Apple Silicon with seemingly no issues.

Thanks for that useful feedback ThatGuySam - I'll close this off on the basis of your report

CMake 3.19 combined with Xcode 12.2 should make universal binaries pretty easy. Both will be included soon in the macOS environment of GitHub Actions, CMake on the next release and Xcode 12.2 is already included, but will be the default on November 30th.

Edit: In the meantime you can checkout this build with Xcode 12.2 to see if it works and how it performs.

Also Xcode 12.3 beta just for fun!

Thanks for the update EwoutH

Looks like GitHub Actions is updated with the lastest XCode to allow this to be built! Exciting.

Unblocked the Xcode version in this PR: #814

Unblocked the Xcode version in this PR: #814

but maintainers still didn't want to make this change..? @EwoutH

The job was refactored and no longer locks xcode version, but M1 support is much more complicated than that.

What is the dealio? What is the big problem?
