c – 使用graphviz绘制自定义BGL图

#include <boost/graph/adjacency_list.hpp>
#include <boost/graph/graphviz.hpp>
#include <boost/utility.hpp>                // for boost::tie
#include <iostream>
#include <utility>                          // for std::pair

using namespace boost;
using namespace std;

class V {};
class C {};

void draw_test(){
    typedef boost::adjacency_list<boost::listS,boost::listS,boost::bidirectionalS,V,C > MyGraph;
        typedef boost::graph_traits<MyGraph>::vertex_descriptor vertex_descriptor;
    MyGraph g;
    vertex_descriptor a = add_vertex(V(),g);
    vertex_descriptor b = add_vertex(V(),g);
    add_edge(a,b,g);
    write_graphviz(std::cout,g);
}

int main() {
    draw_test();

    return 0;
}

但我得到以下错误：

我会非常感谢任何帮助
