Hello, I am trying to build the "6 degrees of kevin bacon" example of the BGL in MSVC 6. When I do I get an "internal compile error". Does anyone know a fix/work-around? The compilation gets to this line (about #73): typedef adjacency_list < vecS, vecS, undirectedS, property<vertex_name_t,std::string >, property < edge_name_t,std::string > > Graph; Graph g; If Graph g is declared I get the following ugly error: d:\program files\microsoft visual studio\vc98\include\xmemory(59) : fatal error C1001: INTERNAL COMPILER ERROR (compiler file 'msc1.cpp', line 1794) Please choose the Technical Support command on the Visual C++ Help menu, or open the Technical Support help file for more information Note that if I change the std::string in vertex_name property to an int the compilation proceeds. Thanks for any help Andy Schweitzer
