What compiler flags are you using? And are you using more than one source file but not using a header to declare the external function(s)? If this kind of error is getting as far as the linker, you either have a poor choice of compiler flags, or you are declaring external functions in your C files rather than in a header file. Either way, it should not be hard to avoid such mistakes (once you know the settings to use, of course).
