If you are getting this error when trying to debug anything with qtcreator:
Could Not Run
No debugger set up.
You need to:
1. go to Tools > Options
2. select Build & Run from left side panel
3. click Kits tab
4. click on Desktop (default), with an exclamation mark near it
5. click Auto-detect.
Debugger row should now say: GDB Engine using "/usr/bin/gdb", and exclamation mark shoud be gone now.
My qtcreator version: community/qtcreator 2.7.0-1
Spend a few hours searching... hope this helps someone.
