I have an error, which says "cannot find -lGL". I'm tryung to install QT on Ubuntu 14.04 everything is ok, but when I want to Build a GUI application I get this error, I surfed the internet for a day and could not find anything. Can someone help me?

Hi and welcome.
You need to install dev-packages
sudo apt-get install libgl1-mesa-dev
Sometimes this helps
sudo apt-get install libglu1-mesa-dev -y
Usually it's already there. Just needs a symlink:
locate libGL.so //locate the lib, in my case it's /usr/lib/x86-64-linux-gnu/mesa/libGL.so.1 sudo ln -s /usr/lib/x86-64-linux-gnu/mesa/libGL.so.1 /usr/lib/libGL.so
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.
