Bug Unity 2022.2.17: Android build fails with Burst 1.8.4

So I was trying out Burst and it looks like it causes the Android build to fail.

If you create a new 3D project and build to Android it will build correctly.

However if you install Burst from the package manager and build to Android it will give an error: "/home/linux/Unity/Hub/Editor/2022.2.17f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang '@/tmp/tmpc94559e.tmp'"

I'm using Ubuntu 20.04.

 

There are three errors:

Library/Bee/artifacts/Android/AsyncPluginsFromLinker: Burst internal compiler error: Burst.Compiler.IL.Aot.AotLinkerException: Non 0 exit code | The native link step failed. Check previous exception in the log - linker command line : "/home/linux/Unity/Hub/Editor/2022.2.17f1/Editor/Data/PlaybackEngines/AndroidPlayer/NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/clang '@/tmp/tmp6214f32e.tmp'"
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&) (at /home/bokken/build/output/unity/unity/Modules/IMGUI/GUIUtility.cs:190)​

 

Building Library/Bee/artifacts/Android/AsyncPluginsFromLinker failed with output:
UnityEditor.Build.BuildFailedException: Burst compiler (1.8.4) failed running

stdout:

At the moment I'm up against a deadline so I have to move on. It shouldn't be too hard to recreate since all you have to do is create a new project and attempt to build it out. Thanks for your time.

 

i have the same problem, how did you fix it??

 

I had the same problem (after an update from 2021 to 2022.3) and I have followed the advice from this thread https://forum.unity.com/threads/errors-when-compiling.1457233/
Change scripting backend from mono to il2cpp (project settings / player / Other settings / Configuration)
Then another error appear saying than clang was not found but again I followed the advice of ifilatov on this thread
https://forum.unity.com/threads/build-failure-on-android-unity-2022-2-0b14.1359823/
and his fix script did work !!
Hope this can help, dear linux users
