Hi all,
I'm enjoying learning the boost graph library. I'm trying to use the Dijkstra algorithm and try to store the shortest path as explained in the subsection "Extending Algorithms with Visitors" of the section "Quick Tour" of the BGL user guide.
When I try to compile my code, I get the following error message:
mesh.cpp:38: error: expected constructor, destructor, or type conversion before '<' token mesh.cpp:38: error: expected `;' before '<' token

You forgot 'struct' or 'class' at the start of line 38 :D. I find it hard to be too amused, since I have done exactly the same thing quite a lot. Duh!! ignore last message. I'm stupider than even _I_ thought! (Must have just been looking at mpl stuff or something?)
