What am I doing wrong. I checked [this](http://answers.ros.org/question/67128/ros-service-why-do-i-have-multiple-definitions-of-main/) but the add_executables seem to be ok. [This is my cmakeList.txt](https://drive.google.com/file/d/0B_MzoTKF7WAibTBiSUdONXZIZ1k/view?usp=sharing)
If i only use the server and client example it error is the same. Did I mix something up?
