Mongo cxx driver issue - undefined reference to `__imp__ZN7bsoncxx7v_

When I’m trying to compile the following code I’m getting so many issues. But mongoc and mongocxx drivers are installed on my pc.

code :

#include <cstdint>
#include <iostream>
#include <vector>
#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/stdx.hpp>
#include <mongocxx/uri.hpp>
#include <mongocxx/instance.hpp>
#include <bsoncxx/builder/stream/helpers.hpp>
#include <bsoncxx/builder/stream/document.hpp>
#include <bsoncxx/builder/stream/array.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()
{
    mongocxx::instance instance{}; // This should be done only once.
    mongocxx::uri uri("mongodb://localhost:27017");
    mongocxx::client client(uri);

    mongocxx::database db = client["sliit"];
    return 0;
}

compiling command :
g++ --std=c++17 main.cpp -o test -IC:/mongo-cxx-driver/include/mongocxx/v_noabi -IC:/mongo-cxx-driver/include/bsoncxx/v_noabi -LC:/mongo-cxx-driver /lib -lmongocxx -lbsoncxx -IC:\local\boost_1_60_0

Can someone please help me regarding this issue?

It looks like you’re following the tutorial here: http://mongocxx.org/mongocxx-v3/tutorial/

-LC:/mongo-cxx-driver /lib

I think you have an extraneous space before /lib. Also, I don’t see any use of boost in your code, so you might want to remove that include directive.

@Bernie_Hackett I think that happens that I’ve used different type of compilers for mongocxx install and project build . I used the same compiler for both and then I get rid of above issue . But I am still getting a error , can you please help me on fixing this issue
