CortexM1 processor

I get the following error when I do build in microvision. The project uses a CortexM1 processor on Altera Cycloneiii FPGA.

The Error:
.\obj\ITCM.axf: Error: L6200E: Symbol ferror multiply defined (by iostubs.o and retarget.o).

The code causing the error:
/* fopen test prg*/

void tst_fopen (void) {
   FILE *fin;

   fin = fopen ("Test.txt","r");

   if (fin == NULL) {
      printf ("File not found!\n");
   }
   else {
      fclose (fin);
   }

}

Iam a Hardware Enginner, not much in the C programming., I was wondering if any one could help me on this issue.

Thanks,
