Hello, I've checked out the newest version of boost from the cvs directory on boost-consulting.com. I've tried to recompile my bgl program to be able to use the latest changes of the bgl code. The compilation progress finished with the following error code: ..\..\..\boost\boost\graph\properties.hpp(169) : error C2248: 'boost::detail::subgraph_property_generator::bind_::type' : cannot access private typedef declared in class 'boost::detail::subgraph_property_generator::bind_' with [ SubGraph=boost::subgraphboost::vecS,boost::vecS,boost::undirectedS,VertexProperty,EdgeProperty>, Property=boost::detail::vertex_property_mapboost::vecS,boost::vecS,boost::undirectedS,VertexProperty,EdgeProperty>,vertex_point_t>::Property, Tag=vertex_point_t ] and [ SubGraph=boost::subgraphboost::vecS,boost::vecS,boost::undirectedS,VertexProperty,EdgeProperty>, Property=boost::detail::vertex_property_mapboost::vecS,boost::vecS,boost::undirectedS,VertexProperty,EdgeProperty>,vertex_point_t>::Property, Tag=vertex_point_t ] Cheers, Stephan [Non-text portions of this message have been removed]
