Bruno, thank you for your continued support.

Here is the first error message, when I try to do intersection(L1, A2, L):
<<

>>

The types _GeometryMultiLinestring and _GeometryMultiPolygon have been defined as follows:
        struct _GeometryMultiLinestring : std::vector<_GeometryLinestring>
        {
        };
        struct _GeometryMultiPolygon : std::vector<_GeometryPolygon>
        {
        };

The following tags have also been defined:
        namespace boost { namespace geometry { namespace traits {
        template <> struct tag<GeoKit::impl::_GeometryMultiPoint>
        {
            typedef multi_point_tag type;
        };
        template <> struct tag<GeoKit::impl::_GeometryMultiLinestring>
        {
            typedef multi_linestring_tag type;
        };
        template <> struct tag<GeoKit::impl::_GeometryMultiPolygon>
        {
            typedef multi_polygon_tag type;
        };
        }}}

Thank you,

Bill
