Hello boost users, Please consider the following example: [code] #include "CGAL/Cartesian.h" #include "CGAL/Polygon_2.h" #include "boost/container/static_vector.hpp" typedef CGAL::Cartesian<double> Kernel; typedef Kernel::Point_2 Point2d; typedef CGAL::Polygon_2<Kernel, boost::container::static_vector<Point2d, 100> > Polygon2d; Polygon2d p; p = Polygon2d(); [/code] Compiling this code snippet with GCC results in following error message: [error] error: no match for 'operator=' in 'p = CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >((*(const Traits*)(& CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >::Traits())))' note: candidate is: CGAL-4.2/include/CGAL/Polygon_2.h:68:7: note: CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >& CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >::operator=(CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >&) CGAL-4.2/include/CGAL/Polygon_2.h:68:7: note: no known conversion for argument 1 from 'sensor::Polygon2d {aka CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >}' to 'CGAL::Polygon_2<CGAL::Cartesian<double>, boost::container::static_vector<CGAL::Point_2<CGAL::Cartesian<double> >, 100u> >&' [/error] I apologize for this concrete example using CGAL, but maybe someone has advice for me? Thanks in advance! Jupp Tscheak
