cfitsio - not opening FITS file

Hi,
  Clive Page is correct.  Try changing your code to

//---------------------------------------------------------------------
Boolean
nrifFrame::readFromFITSFile (const char *fits_name)
{
    // local variables
    fitsfile *fptr;
    int status = 0;
//             ^^^
// That was the change
    
    // open the FITS file
    if (fits_open_file (&fptr,
			fits_name,
			READONLY,
			&status))
    {
	return Error ("Unable to open FITS file");
    }
			
  ........


//---------------------------------------------------------------------

should fix your problem.
