Thread: linking error

When I run my program I get a compiler error saying undefined reference to 'Get_host'
please help

Code:

//im_sender.c


#include "cursor.h"


main (int argc, char *argv [])

{

printf("%s\n",Get_host());
return 0;
}

Code:

//cursor.h

#ifndef CURSOR_H
#define CURSOR_H

char *Get_host(void);
//char *Get_room;
//char *Get_name;

#endif

Code:

//cursor.c

#include "cursor.h"

char Host_port[56];

char* Get_host() {
return Host_port;
}

Yea thats right. I have a makefile, should I include this header file in its makefile
