Ok, so it points to a place in the code where you used it.  You look at 
that and say, yup, I did indeed use it.  Not surprising.  Now, why doesn't 
the linker find it?  Why did the compiler believe it existed?

The site of the usage isn't remotely useful for answering either of those 
questions and those are the ones that form the disconnect between the 
compiler, who believed it existed and let the code pass to the next 
stage), and the linker.
