Mono Compile works, but IL2CPP doesn't

Hello Unity,

When I try to compile the project with Mono settings, it works fine.

But changing it to IL2CPP doesn’t, giving the following error:

Could you please assist me with what can cause this?

Based on the error “The requested operation requires elevation.” your issue seems to be similar to this one Error on build unity 2019.1.9.f1 [SOLVED] .

Thank you for the response JuliusM,

Unfortunately, I tried both possibilities and still get the following error:

Well. the error is different now, so it seems that the solution for the first problem has worked :slight_smile:
Now the errors are

Which means those references are not available when linking Android build. Take a look at your code where they are used. Are they supposed to be used on Android? If they should not be used on Android, wrap that code with

#if !UNITY_ANDROID
#endif

(see Unity - Manual: Conditional compilation in Unity for more information). The difference between mono and il2cpp is that mono only looks for these symbols when they are being used, so if your code logic never gets to them, then everything will work fine even when they are not available. However il2cpp links everything beforehand, so if they are not available, they have to be excluded using the preprocessor directives.
