c++ recursive class dependencies - c++

Question

I'm trying to make something similar to std::Map. I have two classes, NameValue which takes a name and a Value. The class Value can hold data of type int and string. I want the Value class to also accept NameValue to be able to create nested objects. Currently the boost::variant is used to hold the data types allowed to be used.
NameValue.h
#ifndef INC_NAME_VALUE_H_
#define INC_NAME_VALUE_H_
#include <boost/variant.hpp>
#include <iostream>
#include <string>
#include "value.h"
namespace config {
using namespace std;
class Value; // forward declaration
class NameValue {
private:
string name;
Value* valuePtr;
public:
NameValue(){};
NameValue(string name, Value& value)
: name(name)
, valuePtr(&value){};
void Print() {
cout << name << " : ";
// valuePtr->Print();
}
void Set(Value* value) { valuePtr = value; }
};
}
#endif /* INC_NAME_VALUE_H_ */
Value.h
#ifndef INC_VALUE_H_
#define INC_VALUE_H_
#include <boost/variant.hpp>
#include <iostream>
#include <string>
#include "name_value.h"
namespace config {
using namespace std;
using variantDataType = boost::variant<int, string>;
class Value {
private:
variantDataType value;
public:
Value(){};
Value(variantDataType const& value)
: value(value){};
void Print() { cout << value << endl; }
};
}
#endif /* INC_VALUE_H_ */
In Value.h I want to add NameValue to variant like this:
boost::variant<int,string,NameValue> value;
main.cpp
Value i(42);
NameValue nv("meaning", i);
NameValue nv2("nested, NameValue("deep", "value"));//this is what I want
Maybe I'm on the wrong track using variant or the way I'm using dependencies. If there is some other way to make it work I would appreciate the suggestions.
