Cannot used functions defined in header file

My source file starts with:

#include "foo.h"

I am able to use all of my global variables, types, and structs from my header file. In my header file i started with a couple of includes:

#include<file.h>

Then move on to global variables:

#define GLOBAL

Then structs:

#typedef struct boo;

Then types. Then i go to function declarations. I.E:

size_t foo(int*r, size_t nitems);

What am I doing wrong that i am getting linker errors>

Solution

  • The problem's presumably in how you're linking.
