[gdal-dev] gdal-1.11.3 to gdal-2.3.1 compatibility

[Julian Zeidler]

Hi Gane,

it requires only minor modifications. In my Code I have a FLAG 
(HAVE_GDAL2) which makes it compile against both versions.
The changes are along the lines of:

#ifdef HAVE_GDAL2
      GDALDataset *ogrDataset;
#else
      OGRDataSource* ogrDataset;
#endif

#ifdef HAVE_GDAL2
         GDALAllRegister();
         unsigned int  nOpenFlags=GDAL_OF_VECTOR;
        GDALDriver 
*poDriver=GetGDALDriverManager()->GetDriverByName(driver);
         ogrDataset=(GDALDataset*) GDALOpenEx(filename,nOpenFlags, NULL, 
NULL, NULL);
  #else
         OGRRegisterAll();
          ogrDataset=OGRSFDriverRegistrar::Open(filename, FALSE );
  #endif


#ifdef HAVE_GDAL2
                 GDALClose(ogrDataset);
  #else
                 OGRDataSource::DestroyDataSource(ogrDataset);
   #endif


Cheers Julian
