Illegal multi-threaded access to database connection?

[gromiczek]

Hi - While doing an iOS build today for my project using SimpleSQL I got this error:


BUG IN CLIENT OF libsqlite3.dylib: illegal multi-threaded access to database connection

I don't know if it's related but I'm using the 2020 LTS and just upgraded from 2020.3.3 to 2020.3.4 before the build in which this occurred. Any sense what might have happened here? Thanks for your help, and for a great tool!

That looks like an Android error. Be sure you have selected the right platform in the Tools > Options > SimpleSQL menu in Unity.

Hi - yes, iOS is selected there when I get this error.

Sounds like some build settings might have changed in Unity. Be sure you have the managed stripping set to minimal. You might need to experiment with different configuration settings in the build as well. IL2CPP is required. Try different .NET levels.

Also make sure you do not have a Plugins/Android folder in your project. SimpleSQL extracts the Android library here when you select that option in the SimpleSQL settings, but it might be causing issues on iOS.
