It's not difficult (and many people haved use 'c' on all manner of tiny 
processors, I did for z-80s). You could also look at a 'c' language 
primer.... (or- at least put some effort into it; anyone who's written RT 
assembler code should be able to follow the flow and structure).

You're asking everyone else what an ambiguous error message means with only 
the barest of information; often that gets only the barest of response.
