[Boost-users] Trouble with templating of adjacency_list

Perhaps this should go to a g++ group but I have a feeling the answer is Out There: Why is g++ having trouble with this? Error is ../main.cpp:19: error: template declaration of ‘boost::adjacency_list DG’ template<typename T = int> struct POS { T x, y; }; template<typename T> adjacency_list DG;
