Funny you should ask this question, we had the same error pop up yesterday. When VxWorks loads a kernel module (ie your robot code) it makes sure that every function that is called by your code exists somewhere in the running kernel or the previously loaded modules. This check is not done when the code is built or linked.

Look at each symbol it is complaining about and ensure that you haven't made a typo and that the method is actually implemented in your code. Our problem yesterday was that the base class didn't have a method implemented.
