Incremental compiler on mac

Unity Engine

Hey,

it seems that the incremental compiler on Mac is still a bit unstable. We are using the latest version 0.0.42-preview.23 and it seems to break every single time we open the project on mac. We get the following errors:

MissingFieldException: Field 'UnityEditor.Scripting.Compilers.ScriptCompilerBase.m_Island' not found.
UnityEditor.Scripting.Compilers.ScriptCompilerBase.BeginCompiling () (at /Users/builduser/buildslave/unity/build/Editor/Mono/Scripting/Compilers/ScriptCompilerBase.cs:65)
UnityEditor.Scripting.ScriptCompilation.CompilationTask.QueuePendingAssemblies () (at /Users/builduser/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/CompilationTask.cs:236)
UnityEditor.Scripting.ScriptCompilation.CompilationTask.Poll () (at /Users/builduser/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/CompilationTask.cs:143)
...

and

Exception generating network code: System.Exception: Assembly Temp/Unity.Mathematics.dll does not exist!

...

We tried to use the 0.0.42-preview.21 version before and while it works sometimes, it also fails to compile every 3-5 attempt of opening the Unity project.

Does anyone else experience these issues when using Unity 2018.2 with the incremental compiler on mac?

The “m_Island” bug is related to 2018b6 version. Previously preview 22 would get this error on b6 but not on b5. preview 23 fix this error on b6. Are you already on b6 or still b5 because preview 23 is supposed to fix this error.

I’m actually using 2018.2.8 and it seems like preview 23 is causing the error for me. :frowning:
