The following program is giving errors. Please help us!!!


#include <iostream.h>
#include<stdio.h>
#include <stdlib.h>
#include <process.h>
#include <conio.h>
#include <libbcc.h>

int main()
{
  int gdriver=DETECT,gmode, errorcode;
  int  midx,midy;


  initgraph(&gdriver,&gmode,"" );
  errorcode=graphresult();
  if (errorcode!=grOk)
  {
     cout<<"Graphics function error: "<<grapherrormsg(errorcode)<<endl;
     cout<<"Hit a key to stop: ";
     getch();
     exit(1);
  }

  setbkcolor(BLACK);
  setcolor (BLUE);
  closegraph();
  return (0);
}



The program compiled without errors, but while trying to run the program
it gave us following errors

Error: grph1.o: In function 'main':
Error: undefined reference to 'initgraph'
       In function 'setcolor(int)':
       undefined reference to '__gr_color'      
There were some errors

It gave similar errors for 'setbkcolor()' too.
