Hi, My IDE is VC++6.0. I'm on win2k, using boost 1.29.0. I'm trying to get the quick tour (BOOST_HOME/libs/graph/doc/quick_tour.html) of the graph library to compile, but am experiencing a problem. In the example on how to invoke Dijkstra's algorithm, it seems we're calling a function index(*vi). I'm guessing it's supposed to get the node number for the node at vertex_iterator vi. The problem is that my compiler can't find the function ('index' : undeclared identifier). Doing a manual 'search in files' doesn't reveal any legible candidates either. Is this an error in the docs or am I missing something bigger here? kind regards, Dieter Vrancken
