运行下列代码时，出现Undefined symbol‘-EGAVGA_diver’ in module GRAPH.c

错误
请问怎么修正？
谢谢了
#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{
/* request auto detection */
int gdriver = DETECT, gmode, errorcode;

/* register a driver that was added into graphics.lib */
/* For information on adding the driver, see the
/* BGIOBJ section of UTIL.DOC */
errorcode = registerbgidriver(EGAVGA_driver);

/* report any registration errors */
if (errorcode < 0)
{
printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* terminate with an error code */
}

/* initialize graphics and local variables */
initgraph(&gdriver, &gmode, "");

/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) /* an error occurred */
{
printf("Graphics error: %s\n", grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1); /* terminate with an error code */
}

/* draw a line */
line(0, 0, getmaxx(), getmaxy());

/* clean up */
getch();
closegraph();
return 0;
}
