i can compile without the changes

you added the definitions of those functions in each .cpp file they belong in?
it seems like all you did was only add to the .h files and not the .cpp files

i'll review, but i think i've inserted everything

if you had then it's unlikely you'd be getting a LNK2001 error, the exact reason that error occurs is because you do something like this:

in .h file

int someFunction();

but in the .cpp file you don't define this

int someFunction()
{
    return 1;
}
