@Lestev I did not ask you to build your app in the terminal, that you can still do in QtCreator.
What I asked you to do is to run the executable of your application.

[Lestev]

@jsulm hey, the terminal doesn't output anything, it only launches the application

migellestev@Migels-MacBook-Pro build-forBeginner-Clone_of_Qt_6_2_2_for_macOS-Debug % export QT_DEBUG_PLUGINS=1
migellestev@Migels-MacBook-Pro build-forBeginner-Clone_of_Qt_6_2_2_for_macOS-Debug % open forBeginner.app
migellestev@Migels-MacBook-Pro build-forBeginner-Clone_of_Qt_6_2_2_for_macOS-Debug %

Everything works, but inside qt error is keeping

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

[Lestev]

@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/sqldrivers

if 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.

@Christian-Ehrlicher
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

[Christian Ehrlicher]

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.

Then make sure that cmake is installed and in your PATH...

Please tell me how to check it?
exec "$cmake_path" -DCMAKE_TOOLCHAIN_FILE="$toolchain_path" "$@"

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.
