Hi Nicholas, If you haven't already done so, I suggest sending mail to microsoft about this bug in their compiler. Cheers, Jeremy On Apr 20, 2004, at 6:29 PM, Nicholas Burlett wrote:

I'm rather unsure about what is causing this, but I get an internal compiler error in Visual C++ 7.1 when using BGL in some specific circumstances.

I have a graph defined in class Graph defined as such:

typedef property EdgeFeedback; typedef property EdgeSourceJack; typedef property EdgeDestinationJack; typedef EdgeDestinationJack EdgeProperty; typedef boost::property VertexIndexProp; typedef property VertexProperty; typedef adjacency_list graphdata; typedef graph_traits < graphdata >::vertex_descriptor vertdsc;

This definition works fine in the graph.cpp file that implements the class Graph.

However, when I use graph.h in another cpp file, I get bizarre compiler errors: c:\Boost\include\boost -1_31\boost\mpl\aux_\preprocessed\plain\apply.hpp(50) : fatal error C1001: INTERNAL COMPILER ERROR

After some trial and error, I narrowed the problem down to needing to have a != between two oedge_iterators _somewhere_ in the cpp file including graph.h. Simply putting the following function into my other files will cause them to compile just fine:

void makeVChappy() { typedef graph_traits< Graph::graphdata >::out_edge_iterator oedge_iterator; oedge_iterator oiter, oend; oiter != oend; }

I'm a a complete loss as to how this could be happening, but since I have a work-around for now, I'm not going to push the issue too much further at the moment --- I just thought I'd bring this to your attention, and see if anyone knows of a more elegant solution.

Does it compile if you move makeVChappy() into graph.h and declare it inline? At least this would mean graph.h clients need not worry.
