Bug / Crash DllNotFoundException after migrating 2020 Win to 2021 Mac

[josemendez]

Hi,

I tried to keep the subject short. I migrated my project from Unity 2020 LTS on a Windows 10 Laptop to Unity 2021.2.1f1 on a M1 Mac.

It actually went way better than I though but when I enter play mode I get these type of errors spammed with different call stacks. Here are two examples:

Code:

DllNotFoundException: libOni assembly:<unknown assembly> type:<unknown type> member:(null)
Obi.OniBackend.CreateSolver (Obi.ObiSolver solver, System.Int32 capacity) (at Assets/Obi/Scripts/Common/Backends/Oni/OniBackend.cs:17)
Obi.ObiSolver.Initialize () (at Assets/Obi/Scripts/Common/Solver/ObiSolver.cs:862)
Obi.ObiSolver.AddActor (Obi.ObiActor actor) (at Assets/Obi/Scripts/Common/Solver/ObiSolver.cs:1123)
Obi.ObiActor.AddToSolver () (at Assets/Obi/Scripts/Common/Actors/ObiActor.cs:338)
Obi.ObiActor.OnEnable () (at Assets/Obi/Scripts/Common/Actors/ObiActor.cs:313)

Code:

DllNotFoundException: libOni assembly:<unknown assembly> type:<unknown type> member:(null)
Obi.OniColliderWorld.SetColliders (Obi.ObiNativeColliderShapeList shapes, Obi.ObiNativeAabbList bounds, Obi.ObiNativeAffineTransformList transforms, System.Int32 count) (at Assets/Obi/Scripts/Common/Backends/Oni/OniColliderWorld.cs:40)
Obi.ObiColliderWorld.UpdateWorld (System.Single deltaTime) (at Assets/Obi/Scripts/Common/Collisions/ObiColliderWorld.cs:388)
Obi.ObiUpdater.BeginStep (System.Single stepDeltaTime) (at Assets/Obi/Scripts/Common/Updaters/ObiUpdater.cs:42)
Obi.ObiFixedUpdater.FixedUpdate () (at Assets/Obi/Scripts/Common/Updaters/ObiFixedUpdater.cs:44)

I tried reimporting from package manager and restarting unity. I still get those errors.

Hi,

Make sure the /Obi/Plugins folder exists and actually contains the library file for your platform (libOni.a on mac). I’ve only seen this fail when A) the asset was freshly imported with no Unity restart , or B) missing plugin files.

If neither is the case, would you mind sending your project to support(at)virtualmethodstudio.com so that I can take a closer look? Thanks!
