Здравствуй, I can't reproduce this error on 3.2`s branch. Everything works fine to me. However, this error occurs in branch 4.0 due to the modifications that were made to the engine. Make sure you are trying to compile for branch 3.2, not the master. I plan to start working on a version for Godot 4 when the engine becomes more stable.

Привет, Yes, youre right. It was master-branch. 3.2 compiles perfectly well. Waiting for 4.0 mysql plugin. Thanks.

I just added support for Godot 4. Now I believe you can compile it without errors. Remember to define your SCsub file correctly.
