Hi! I'm new to GDAL and I've just started to do a test implementation to see how it works. There is one problem though, after including "gdal_priv.h" my VC6 sp5 compiler says that "class 'GDALDefaultOverviews' needs to have dll-interface to be used by clients of class 'GDALDataset'" (line 232). Any ideas what might be the problem? - Andreas
