What is a good strategy for finding undefined symbols...

[WhatMeWorry]

I've been trying to compile the DerelictGL and finally got it to 
compile cleanly. But now the linker is complaining.

I've been "searching" for hours for these definitions and I feel 
like I've just been going around in circles.

What is a novice to do?   Is this just something I am supposed to 
know before hand?
