Hello,

I have this issue when building in 2019.4.12f Any idea on what the problem could be please?

API Level: Android 8.0 (Oreo level 26)
API Compatibility Level: .Net 4.x
Scripting Backend IL2CPP
Target Architectures: ARM64

Exception: C:\Program Files\Unity\Hub\Editor\2019.4.12f1\Editor\Data\il2cpp/build/deploy/net471/il2cpp.exe did not run properly!

Thanks! :slight_smile:

This failure occurs because the code in the project has extern methods in C#. Methods marked as extern with a the [Dllimport(“__Internal”)] attribute must be present in a native library that is linked with the Unity player when building with the IL2CPP scripting backend.

For example, this in this project one function which causes this issue is named: GetBlendShapesInfo

You have two options:

  1. Build a native library with all of the methods marked as extern with the [Dllimport(“__Internal”)] attribute for the target platform and architecture of the player. See this documentation for details about native plugins: Unity - Manual: Native plug-ins

  2. Remove the C# code which defines this extern method. You can do that with platform dependent compilation: Unity - Manual: Conditional compilation
