Description

Build error when compiling using IL2CPP for Android if project uses static NetworkVariables. This behaviour happens when attempting to build using IL2CPP scripting backend and building to Android. Building to Android using Mono builds successfully with no errors, leading me to believe this is a bug/unintended.

Reproduce Steps
  • Declare a static NetworkVariable in a NetworkBehaviour script. (public static NetworkVariable<int> in my case)
  • Set scripting backend to IL2CPP
  • Set build platform to Android
  • Build
  • Error displayed as shown in Additional Context section
Actual Outcome

Build fails with two error messages in console.

Expected Outcome

Build should compile successfully with no errors.

Screenshots

Error in Console:
