I'm trying to connect mongdb with mongocxx driver in my C++ sample code. I added Additional include, Libraries and dependencies. When I build it it shows following error.
this is the full code
#include "stdafx.h"
#include <cstdint>
#include <iostream>
#include <vector>
#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
#include <mongocxx/uri.hpp>
#include <mongocxx/stdx.hpp>
using bsoncxx::builder::stream::close_array;
using bsoncxx::builder::stream::close_document;
using bsoncxx::builder::stream::document;
using bsoncxx::builder::stream::finalize;
using bsoncxx::builder::stream::open_array;
using bsoncxx::builder::stream::open_document;
int main() {
std::cout << "Hello, World!" << std::endl;
mongocxx::instance instance{}; // This should be done only once.
mongocxx::uri uri("mongodb://localhost:27017");
mongocxx::client client(uri);
return 0;
}
thi
s is the error output.

It says what it says initialized your driver first. if you have compiled your driver correctly these codes must be working.
