[Gdal-dev] gdalwarp tutorial VS2003 compile error

[Huajun Zhang]

 The code is as following:

    // Get Source coordinate system. 
    const char *pszSrcWKT, *pszDstWKT = NULL;

    pszSrcWKT = GDALGetProjectionRef( hSrcDS );
    CPLAssert( pszSrcWKT != NULL && strlen(pszSrcWKT) > 0 );

    // Setup output coordinate system 
    OGRSpatialReference oSRS;

    oSRS.SetACEA( 29.5, 45.5, 23.0, -96.0, 0.0, 0.0);
    oSRS.SetWellKnownGeogCS( "NAD83" );
    oSRS.exportToWkt( &pszDstWKT );

 Error message:  error C2664: 'OGRSpatialReference::exportToWkt' : cannot 
convert parameter 1 from 'const char **__w64  ' to 'char ** '

Thanks

You're probably passing const pointer where non-const is expected.
Please, show us exact code you're using, with line where you call
exportToWkt().

Cheers
