Linker Errors

hardcore (2)
I have these two classes, where Delivery is multiply dependent on Coord. The goal I'm aiming for is so that Delivery will have #include "Coord.h" on top. Somehow when I do that It gives out a bunch of Linker errors saying undefined reference to Coord::Coord(). However, putting in #include "Coord.cpp" on top fixes the thing. I dont want that. How come it doesnt work?

EDIT: Edited using Zaita's find

Should be:
1
2
3
 
Coord Delivery::getLocation(){
	return this->location;
}


As should your definition in the class.

Thanks for that. Code has been edited. However, the Linker errors are still there. Anymore mistakes you noticed?
