Hello once again, guys.

I'd like to thank you guys for taking your precious time to help me.  I, once again, need some assistance.

Here's the code from "hubba.c":
#include <unistd.h>
#include <stdlib.h>
#include "../include/sane/sane.h"
#include "../include/sane/config.h"
#include "../include/sane/sanei.h"
#include "../include/sane/sanei_usb.h"

/* Declare any prototypes */
SANE_Status status;

int main(void) {

SANE_Int fd;

/* Start up the usb_interface */

/* Try to access the usb device */
status = sanei_usb_open("/dev/usb/scanner0",fd);

/* Check the status */
if (status != SANE_STATUS_GOOD) {
  return -1;

/* Try to close the USB device */


And here's the error message I recieve:
 gcc hubba.c
hubba.c: In function `main':
hubba.c:27: warning: passing arg 1 of `sanei_usb_close' makes integer from pointer without a cast
/tmp/ccWqpZ3d.o(.text+0x11): In function `main':
: undefined reference to `sanei_usb_init'
/tmp/ccWqpZ3d.o(.text+0x21): In function `main':
: undefined reference to `sanei_usb_open'
/tmp/ccWqpZ3d.o(.text+0x46): In function `main':
: undefined reference to `sanei_usb_close'
collect2: ld returned 1 exit status

Some have suggested just to use "&fd" in both of the functions (sanei_usb_open and sanei_usb_close).  That is what I am going to use.  But I can't seem to link the file to another file such as "sanei_usb.lo".  I have given the full path to the file, but to no avail, such as in "gcc -l /path/to/object/file/ hubba.c".

Thank you again in advance.
