Error when trying to run a ros node

edit

I have this example ros publisher I have created for debugging purpose. It builds withouth any problem but when i rosrun the ros code, I get these errors and I dont where its coming from and why my publisher does not work. I will be happy with anyone who can help me. I used catkin clean to clean everything and build it again but it still did not work out.
