Как инициализировать метод в программе

---

привет,
у меня есть следующий метод в моей программе при построении программы
метод неинициализирован, как показывает эта ошибка
то, что я попробовал, находится ниже

METHODDEF(void)
put_pixel_rows (j_decompress_ptr cinfo, djpeg_dest_ptr dinfo,
		JDIMENSION rows_supplied)
/* This version is for writing 24-bit pixels */
{
  bmp_dest_ptr dest = (bmp_dest_ptr) dinfo;
  JSAMPARRAY image_ptr;
  register JSAMPROW inptr, outptr;
  register JDIMENSION col;
  int pad;

  /* Access next row in virtual array */
  image_ptr = (*cinfo->mem->access_virt_sarray)
    ((j_common_ptr) cinfo, dest->whole_image,
     dest->cur_output_row, (JDIMENSION) 1, TRUE);
  dest->cur_output_row++;

  /* Transfer data.  Note destination values must be in BGR order
   * (even though Microsoft's own documents say the opposite).
   */
  inptr = dest->pub.buffer[0];
  outptr = image_ptr[0];
  for (col = cinfo->output_width; col > 0; col--) {
    outptr[2] = *inptr++;	/* can omit GETJSAMPLE() safely */
    outptr[1] = *inptr++;
    outptr[0] = *inptr++;
    outptr += 3;
  }

  /* Zero out the pad bytes. */
  pad = dest->pad_bytes;
  while (--pad >= 0)
    *outptr++ = 0;
}

Что я уже пробовал:

METHODDEF(void)
put_pixel_rows (j_decompress_ptr cinfo, djpeg_dest_ptr dinfo,
		JDIMENSION rows_supplied)
/* This version is for writing 24-bit pixels */
{
  bmp_dest_ptr dest = (bmp_dest_ptr) dinfo;
  JSAMPARRAY image_ptr;
  register JSAMPROW inptr, outptr;
  register JDIMENSION col;
  int pad;

  /* Access next row in virtual array */
  image_ptr = (*cinfo->mem->access_virt_sarray)
    ((j_common_ptr) cinfo, dest->whole_image,
     dest->cur_output_row, (JDIMENSION) 1, TRUE);
  dest->cur_output_row++;

  /* Transfer data.  Note destination values must be in BGR order
   * (even though Microsoft's own documents say the opposite).
   */
  inptr = dest->pub.buffer[0];
  outptr = image_ptr[0];
  for (col = cinfo->output_width; col > 0; col--) {
    outptr[2] = *inptr++;	/* can omit GETJSAMPLE() safely */
    outptr[1] = *inptr++;
    outptr[0] = *inptr++;
    outptr += 3;
  }

  /* Zero out the pad bytes. */
  pad = dest->pad_bytes;
  while (--pad >= 0)
    *outptr++ = 0;
}
