You have to pass the result type as an argument to static_visitor template. Maybe you meant something like this:

 //...  AttributeValue(int i) : Value(i)  {}  AttributeValue(double d) : Value(d)  {}  // etc...

 struct get_min_visitor : public boost::static_visitor<AttributeValue>  {   template <typename T>   AttributeValue operator()(const T &) const   {     return std::numeric_limits<T>::min();   }  };

Thanks, I could even get it working with: template <typename T> AttributeValue(T t) : Value(t) {} Thanks -- Mathieu
