I'm trying to execute the following code but I'm ending up getting issues I am getting an error called error LNK2019: unresolved external symbol and NMAKE: fatal error U1077: I don't have any idea of fixing this Can someone please help me to fix this? my msvc version is 19.28.29913 and mongocxx version is 3.6.2

code :

#include <iostream>
#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>

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;
}

Error :

  • Does this answer your question? [What is an undefined reference/unresolved external symbol error and how do I fix it?](https://stackoverflow.com/questions/12573816/what-is-an-undefined-reference-unresolved-external-symbol-error-and-how-do-i-fix) – 273K Mar 22 '21 at 04:29
  • NO I don't see a way to resolve my issue :( – Tharindu Balasuriya Mar 22 '21 at 04:40
  • If you use CMake for build your project, then exactly `CMakeLists.txt` script is responsible for linking with the libraries. Show that script (add it to the question post). – Tsyvarev Mar 22 '21 at 08:12
  • Yes issue was on the CMake List, i fixed it as follow,now its working, Thankyou verymuch – Tharindu Balasuriya Mar 22 '21 at 09:52
  • `cmake_minimum_required(VERSION 3.17) project(untitled4) find_package(libmongocxx REQUIRED) find_package(libbsoncxx REQUIRED) include_directories(${LIBMONGOCXX_INCLUDE_DIR}) include_directories(${LIBBSONCXX_INCLUDE_DIR}) include_directories("C:/mongo-cxx-driver/include/mongocxx/v_noabi") include_directories("C:/mongo-cxx-driver/include/bsoncxx/v_noabi") include_directories("C:/local/boost_1_75_0") set(CMAKE_CXX_STANDARD 17) add_executable(untitled4 main.cpp) target_link_libraries(untitled4 ${LIBMONGOCXX_LIBRARIES}) target_link_libraries(untitled4 ${LIBBSONCXX_LIBRARIES}) ` – Tharindu Balasuriya Mar 22 '21 at 09:52

    I've edited the question with the CMake List, for anyone getting the same issue – Tharindu Balasuriya Mar 22 '21 at 09:53
