Qt and embedded Firebird DB

Hello!

I am having some difficulties to find a tutorial to use Qt with embedded Firebird DB for Mac OSX.

Could anyone help to find how to do that?

Thanks

I create a small project whit this library using qt4. maybe still works using qt5.

I have installed Qt 5.4 and Firebird 2.5 (Mac OS X 64-bit Classic, Superclassic & Embedded – Intel)
The Firebird 2.5 installation creates a firebird.framework at my computer. Now I am trying to make a connection with Qt but I receive a “driver not loaded” message.

I am not figuring out how to link the plugin with Qt. How can I do that?

Thanks
