Why do ROS Navigation Stack plugins need to have a header file?

I have made some global path planner plugins and have noticed a rather peculiar error when trying to run those planners without a header file. Of course I am including the necessary stuff to the CPP file having the class implementation, but everytime I try to run it gives error with move_base exiting with code 127. Do you guys have any idea about why it happens?
