extern defined functions

I am trying to include externally defined functions in my main function but when I try to compile using:

Code:

cc assemble.c pass1.o pass2.o getsource.o -o assemble

I get the following errors:

Code:

Here is the code in my assemble.c program that is trying to include the externally defined functions:

Code:

/* Pre-Processor Directives */
#include "cop3601.h"
#define SYMBSIZE 10
#define SYMBLIMIT 200
#define SOURCELIMIT 500

typedef struct
{
   char symbol[SYMBSIZE];
   int value;
   int casenmbr;
   int otherinfo;
} tabletype;

typedef struct
{
   char *lbl;
   char *opc;
   char *opr1;
   char *opr2;
   int *ni;
   int *xbpe;
} comptype;

extern int getsource();
extern int pass1();
extern int pass2();

char sourcelist[SOURCELIMIT][81];
int sourcecnt;
int errors[SOURCELIMIT];
tabletype symbtab[SYMBLIMIT];
int symbtabsize;
tabletype codetable[]=
{
   #include "codetable"
};
int codetabsize = sizeof(codetable)/sizeof(tabletype);
char objline[81];

/* Prototypes */
int getsource(char *filename[]);
int pass1(void);
int pass2(void);

int main(int argc, char *argv[])
{ }

Somebody has to write those functions that are missing. If it wasn't supposed to be somebody else, I guess that somebody is you.

I have the functions written, and they're in the same directory

Then compile them, and link them with everything else.

that's what I'm trying to do but when I compile it still says it has an undefined reference

You didn't put any of the functions in assemble.c. What file did you put them in? You need that file too.

Ok, I figured out a way to compile it that seems to resolve the issue, thanks for the help
