Chris: This usually happens when you build mix different versions of geos, i.e. build with the 3.1 lib but the 2.2.3 headers, or link with the 3.1 shared lib and then have it pick up the 2.2.3 shared lib at run time. Do you have two versions of geos on your system? If so, make sure basemap is only finding one of them, both at build time and run time. -Jeff ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
