无法链接Boost Graph库以获取read_graphviz()示例 [英] Can not link Boost Graph Library for read_graphviz() example

问题描述

我试图用read_graphviz做一个例子，但我不能帮助链接器将read_graphviz函数调用链接到正确的版本read_graphviz.

I am trying to do an example with read_graphviz but I can not help the linker to link the read_graphviz function call to the correct version read_graphviz.

在 http://www.boost.org/doc/libs/1_61_0/libs/graph/doc/read_graphviz.html ，有三种read_graphviz模板版本: 命名空间提升{

At http://www.boost.org/doc/libs/1_61_0/libs/graph/doc/read_graphviz.html there are three template versions of read_graphviz: namespace boost {

  template <typename MutableGraph>
  bool read_graphviz(std::istream& in, MutableGraph& graph,
                     dynamic_properties& dp,
                     const std::string& node_id = "node_id");

  template <typename MutableGraph>
  bool read_graphviz(std::string& str, MutableGraph& graph,
                     dynamic_properties& dp,
                     const std::string& node_id = "node_id");

  template <typename InputIterator, typename MutableGraph>
  bool read_graphviz(InputIterator begin, InputIterator end,
                     MutableGraph& graph, dynamic_properties& dp,
                     const std::string& node_id = "node_id");
}

我正在尝试调用它的第二版. 这是我的示例代码:

I am trying to call the second version of it. Here is my example code:

#include <boost/graph/graphviz.hpp>
#include <boost/tuple/tuple.hpp>
#include <boost/graph/adjacency_list.hpp>
#include <boost/property_map/dynamic_property_map.hpp>
#include <boost/graph/graph_utility.hpp>

using namespace boost;

typedef boost::adjacency_list < 
    boost::vecS,
    boost::vecS,
    boost::undirectedS,
    boost::property<boost::vertex_index_t, int>,
    boost::property<boost::edge_index_t, int>> Graph;


int main(int argc, char** argv)
{

  Graph dual_g;

  boost::dynamic_properties dp;

  boost::property_map<Graph, boost::vertex_index_t>::type vIndex = get(boost::vertex_index, dual_g);
  dp.property("vertex_id",vIndex);

  boost::property_map<Graph, boost::edge_index_t>::type eIndex = get(boost::edge_index, dual_g);
  dp.property("edge_id", eIndex);

  read_graphviz("dtest.dot", dual_g , dp); //, "node_id");


  return 0;
}

我尝试使用以下命令进行编译:

I trying to compile using the command:

g++ -std=c++11 main.cpp -o main -lboost_system 

错误:

推荐答案

您需要链接功能的实现.

You need to link the implementation of the functions.

最简单的方法是将其包括在内:

Simplest way is to include it:

#include  <libs/graph/src/read_graphviz_new.cpp>

如果您希望获得更多灵感示例: read_graphviz src

In case you like more samples for inspiration: read_graphviz src
