I'm using Ubuntu 12.04 64bit. Recently I installed "qt-linux-opensource-5.0.0-x86_64-offline" and "Qt Creator 2.6.1"
The problem is when I press run or CTRL+R, It gives me ERROR message.
Here is the Screen shot :

Install OpenGL runtime package for your system (it will probably be part of your display drivers or MESA).
