QSqlDatabase: QMYSQL driver not loaded

Hello there,
I've got a problem with the MySQL driver in my QT- C++ project.
I already tried several solutions from the internet but nothing worked.
Under C:\Qt\6.3.1\Src\qtbase\src\plugins\sqldrivers is already a MySQL folder with the driver files.

The error call is:
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QODBC QPSQL

My used QT- version is 6.3.1 in Visual Studio 22.
Is there any solution I could try next? The project code is at Github.

Thanks for youre help!
Patrick

Do the built drivers exists there, or just the sources? And is that directory one where Qt applications look for drivers?

@JonB

That's all what's in the folder, but when I look in the preinstalled SQLite folder, it looks the same.
How can I figure out wheather the QT Application looks there for drivers? I found the path in another forum to look at.
Best regards, Patrick

Those are source files. You need to build the driver, or I don't know if somewhere Windows still allows a pre-built download, have a Google.

@Patsch36 need to install libmysql.dll and follow Readme

@anil_arise
Thanks for your answer!
I followed the instructions step by step and the driver got installed.
Now the error message is
QSqlDatabase: QMYSQL driver not loaded
QSqlDatabase: available drivers: QSQLITE QMARIADB QMYSQL QODBC QPSQL
How can be the driver now available but does still not work?

Set QT_DEBUG_PLUGINS environment variable before starting your app, then post the output from terminal here.
