Hi I'm trying to run a functor over edges from a graph using for_each however it fails when the iterators are edges. The same technique works for iterators to vertices. Here is the compiler error: g++ -o bind_edge_test bind_edge_test.cpp /usr/lib/gcc/i686-pc-linux-gnu/4.1.1/include/g++-v4/bits/stl_algo.h: In function '_Function std::for_each(_InputIterator, _InputIterator, _Function) [with _InputIterator = boost::detail::undirected_edge_iter<std::_List_iterator<boost::list_edge<void*, boost::property<boost::edge_name_t, unsigned int, boost::no_property>
, boost::detail::edge_desc_impl<boost::undirected_tag, void*>, int>, _Function = boost::_bi::bind_t<void, Op, boost::_bi::list2<boost::arg<1>, boost::_bi::value<int> > >]': bind_edge_test.cpp:79: instantiated from here /usr/lib/gcc/i686-pc-linux-gnu/4.1.1/include/g++-v4/bits/stl_algo.h:159: error: no match for call to '(boost::_bi::bind_t<void, Op, boost::_bi::list2<boost::arg<1>, boost::_bi::value<int> > >) (boost::detail::edge_desc_impl<boost::undirected_tag, void*>)'
I've attached the file. Thanks for the help. -- sashan http://sashang.orcon.net.nz/
