boost and stl problem - std::string

Hello,

I want to use ExprNode to store AST informations.
But I fail.
How can I overgive parameters to class ExprNode?

Here are the code sippets:



template <typename TN>
class ExprNode
{
public:
     struct ExprNode *operand1;
     struct ExprNode *operand2;

     char opr;
     int  num;

     ExprNode(char op, struct ExprNode *e1, struct ExprNode *e2)
     {
         opr = op;
         operand1 = e1;
         operand2 = e2;
     }

     ExprNode(int n)
     {
         num = n;
         operand1 = operand2 = nullptr;
     }

     ExprNode() { }

     template<TN>
     ExprNode(TN t, std::string *p1, std::string *p2)
     {
         if (t == 2)
         {
             std::cout << "classler" << endl;
         }
     }
};



         class_definition
             = (tok.kw_class          >> *comments
                 >> tok.identifier    >> *comments
                 >> tok.kw_of         >> *comments
                 >> tok.identifier    >> *comments >> class_body
                 >> tok.kw_endclass)
/* line: 181 */ [
                     ExprNode<int>(
                     2,
                     phx::construct<std::string>(_1),
                     phx::construct<std::string>(_2))

                     //expnode->add(2,"val(_1)","val(_2)")
                     //phx::construct<std::string>(_1),
                     //phx::construct<std::string>(_2))
                 ]
             ;
