thinks @koahnig for your reply

See https://forum.qt.io/topic/26395/how-to-solve-issue-cannot-find-lgl-in-qt5-installed-in-ubuntu

Try to start your computer and then press Strg-Alt-F1. You then should see the text console (you can go back to graphic mode via Alt-F7). Does the text-console work?

Hi and welcome to devnet,

Installing the libgl1-mesa-dev package is the correct solution. libGL's location can change depending on whether you are using a 32 or 64 bit version of Ubuntu.

Note that this question has already been asked many times on this forum, you should search without the minus before lGL.

@jsulm Library file what is very important for building 32-bit?

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
