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;

You are not allowed to have a templated variable declaration. Did you intend to do a template typedef? Those are C++0x only and have a different syntax. -- Jeremiah Willcock
