问题
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.
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");
}
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;
}
I trying to compile using the command:
g++ -std=c++11 main.cpp -o main -lboost_system
The Error:

You need to link the implementation of the functions.
Simplest way is to include it:
#include <libs/graph/src/read_graphviz_new.cpp>
In case you like more samples for inspiration: read_graphviz src
