int main( int argc, char **argv )
{
//
 GDALDataset  *poDataset;
 GDALRasterBand  *poBand;

 GDALAllRegister();

 poDataset = (GDALDataset *) GDALOpen( "c:\output.jpg", GA_ReadOnly );

 // one program (which has only these  codes )is ok ,
//the other(which has other program writen by    qt  )  failed.   

if( poDataset == NULL ) 
 {
  cout<<"fail to  read file!"<<endl;
