Linux command line build of macOS has wrong mono path

I kept getting the following error on my build machine, running Ubuntu and Unity 2021.2.3f1

Code (CSharp):

1.   ##### Output
2. 15:11:58  System.ArgumentException: Copy() called on path that doesnt exist: /home/ghost/Unity/Hub/Editor/2021.2.3f1/Editor/Data/PlaybackEngines/MacStandaloneSupport/Variations/macos_x64ARM64_player_nondevelopment_mono/UnityPlayer.app/Contents/Frameworks/UnityPlayer.dylib

I went to look for the path including "macos_x64ARM64_player_nondevelopment_mono"
and realized it's wrongly capitalized, and should be "macos_x64arm64_player_nondevelopment_mono"

I was able to fix it, and get proper builds by running

Code (CSharp):

1. sudo ln -s /home/myuser/Unity/Hub/Editor/2021.2.3f1/Editor/Data/PlaybackEngines/MacStandaloneSupport/Variations/macos_x64arm64_player_nondevelopment_mono  /home/myuser/Unity/Hub/Editor/2021.2.3f1/Editor/Data/PlaybackEngines/MacStandaloneSupport/Variations/macos_x64ARM64_player_nondevelopment_mono

I am unsure how or where to report a bug for this issue, since I don't ever open the editor on the buildmachine.
Steps to reproduce:
- build from command line with target platform as OSXStandalone, on a Linux machine

 

Just observed that this is still an issue in 2021.2.11

 

Still an issue, although creating a symbolic link worked

 

Please submit a bug report

 

I submitted a bug report with summary x64arm64/x64ARM64 Case Issue When Building a MacOS Application on Linux on June 3rd. Thank you!

 

You will want to post the BugID to be complete, and reference this forum thread in the bug also.

 

Hi, I mentioned the link to this forum in my bug report. I'll give you the ID once it is verified and posted on Issue tracker.

 

I also reported this on the day I posted this thread,
https://fogbugz.unity3d.com/default.asp?1403968_34n83gcqppt8e6um

It is now closed, but looks like it wont' be fixed for 2021.
Issue still exist in 2021.3.7f1, but the symlink solution still works, just need to redo it every time you update.

 

Fix confirmed on 2021.3.30f1 (so bug was fixed somewhere between 2021.3.7f1 and 2021.3.30f1). I can now build for macOS on Linux without using the symlink hack (and yes I'm sticking to 2021 because it's an old project, but I remember I could build for macOS without issues on 2022.1.24f1 so it was also fixed on 2022).
