I’m getting this error when I run a console-based project from Qt Creator in Kubuntu. The Konsole terminal pops up but it only says:
Cannot connect creator comm socket /tmp/qt_temp.JH2103/stub-socket: No such file or directory
Press <RETURN> to close this window...
I had the same problem in Ubuntu 11.10 after installing Qt Creator with apt-get. If you will go to Qt Creator settings and change the terminal to
/usr/bin/xterm -ethen it should work.
