Just in case someone runs into the same problem and wonders what to install. I have started out with a fresh Ubuntu 13.10 install on VirtualBox and ran into the same problem after I had installed the pre-build of Qt 5.2.0 with Qt creator. In my case the libxcb was apparently missing. However, I have installed ICU first, but this did not solve the problem. Therefore, I have started these commands in a terminal: @ sudo apt-get install libicu-dev sudo apt-get install "^libxcb.*" libx11-xcb-dev libglu1-mesa-dev libxrender-dev @
