Can't working MYSQL database in qt (QSqlDatabase: available drivers: QSQLITE QODBC QPSQL)

@Lestev OK, then we need to debug now.
Do this on console:- Go to the build folder of your application
- Do: export QT_DEBUG_PLUGINS=1
- Run your app from the terminal
- Copy paste the output from terminal to here
You can also set QT_DEBUG_PLUGINS in Run settings of your project in QtCreator.

What I asked you to do is to run the executable of your application. -

Don't call open, use the full path to the executable in the bundle.

@SGaist hi, I think my directory is not properly defined because it should be /Users/migellestev/Qt/6.2.3/macos/plugins/sqldrivers
but directory is:
/Users/migellestev/Qt/QtDesignStudio/qt6_design_studio_reduced_version/plugins/sqldriversif it helps:
-
Looks like you're mixing up Qt versions which is not possible. Make sure QtDesignStudio is not picked up, only your Qt6.2.2 where you also (hopefully) build your Qt mysql plugin for. Currently it looks like you created (or had by default - don't know) the plugin inside QtDesignStudio.

Thanks for your response very much,
But i verify my path and got that this path used by default, but why?
I reinstalled qt and got the same

Don't know MacOS but on linux this means you have the other somewhere in your LD_LIBRARY_PATH or ld.so.conf. Remove it /make sure the correct path comes first.

I don't understand. If you want to build Qt or one of it's plugins you have to install cmake and make sure it's found in your PATH.
