Qt Creator 3.3.0 fails to start debugging on Ubuntu 14.10 x64

Violet Giraffe

When I press "Debug", Creator switches to debug perspective and nothing else happens. I don't even see GDB in the list of running processes. What;s the deal? It used to work on Ubuntu 13.10 with older Creator.

P. S. GDB version 7.8.

Hi,

I'm working in the same environment and switching to 14.10/3.3.0 made no problems.
GDB has been autodetected in /usr/bin/gdb (Tools->Options->Build & Run)

Violet Giraffe

GDB is detected no problem.
If I wait long enough, 20-30 minutes, debugging does eventually start.

My colleague has the same problem on a different computer with Ubuntu and the latest Qt as well.

clochydd

Do you have the same problem with different programs? E.g. one simple Qt-example? My programs debug perfectly on two different computers (desktop & notebook with Ubuntu 14.10).

Violet Giraffe

Good point. No problem with an example.
What could possibly cause this issue?

I'm not sure if this is related but I've similar problems on Windows with Qt5.4.0/MinGW4.9.1 and I've already created a bugreport:
"QTCREATORBUG-13771":https://bugreports.qt-project.org/browse/QTCREATORBUG-13771

Violet Giraffe

No, that's not the problem I'm having.

Actually I have no idea - perhaps it has to do with a special plugin you are using... As a next step I would try examples including my plugins - if any.

Violet Giraffe

What is a plugin in this context? I don't think I use any.

clochydd

Just thinking of SQL, graphics, web - all the things your program uses but the running example does not...

Violet Giraffe

Ah, you mean Qt modules? I use a pretty basic set: core, gui, widgets, network, xml and opengl.

clochydd

Yes, that's what I meant and now I would test with a Qt opengl example first...
