I am trying to compile a simple program to load an image in code block and eclipse. I am getting the following compilation error

I tried reinstalling qt by using the command as suggested by some people in some other groups.

sudo apt-get install qt5-default qttools5-dev-tools

But no use. Anyone got a solution for this?
