Please check out my reference [2] in my initial post.

I was even daydreaming of running lldb in a console myself, as I have done some times with gdb. ;)

Oh no, I just built the project myself using make and then just let Xcode run the code. The project is then an external build project.

Yes, you’re right. I keep forgetting that. When looking at those threads this morning I was thinking along those lines.

Did so as well, but this didn’t fix it.
It looks as if Konversation’s GUI gets half-deadlocked by OSX itself, perhaps...

The only challenge will be to get it to execute cmake with the MacPorts specific options and environment, or get it to accept an existing build directory without insisting on doing a cmake of its own in there.

OK, will test that. I have managed to build and run Linux-qmake-based projects fine on OSX with Qt-Creator.
Well, let’s see how this will turn out. :)
