On Windows debugging in QtCreator is quite simple. But I've not managed to do the same on Ubuntu Linux. I got the message that no debug version is built. What should I do in order to be able to debug?
(The same question is in the forum general discussion as a reply to my own question how to install gdb on Ubuntu, since this seems to be more suitable there. Now I think the debug question is a topic for this forum. Excuse me for double posting.)
