Hi, I’m working on a project in Qt Creator and I’m trying to integrate mongocxx into the project. I downloaded the mongo c driver (1.17.0), boost (1.7.3), and the mongocxx driver (3.6.0) according the documentation and everything seemed to build successfully (I used “Visual Studio 15 2017 Win64” with the -G flag). In my .pro file, I added include paths and libs for the driver, and my project manages to build and execute successfully with mongocxx includes in my header files. However, as soon as I try to add any code that uses mongocxx (like the line mongocxx::instance inst{};), the program crashes when I try to execute it and will continue to crash until I comment out the code and clean/rebuild the project (error message only says “The program has unexpectedly finished”).
It seems like I didn’t connect my project to the mongocxx driver correctly, but I’m not sure what else to check, so any suggestions would be appreciated! I’m using a kit with Qt 5.15.0 MSVC 2015 64-bit to build and run my project.
test code:
#include "database_utils.h"
#include <bsoncxx/builder/stream/document.hpp>
#include <bsoncxx/json.hpp>
#include <mongocxx/client.hpp>
#include <mongocxx/instance.hpp>
#include <iostream>
// reference: https://docs.mongodb.com/drivers/cxx
bool connectToDatabase() {
std::cout <<"in connect!" << std::endl;
// execution fails if this code is uncommented (and print statement above is not reached)
// try {
// mongocxx::instance inst{}; // This should be done only once.
// mongocxx::client conn{
// mongocxx::uri{
// "mongodb+srv://admin:dPJk8Uj0idkQ5Kqc@csas-cluster.w3smq.mongodb.net/csas?retryWrites=true&w=majority"
// }
// };
// } catch (...) {
// std::cout << "caught" << std::endl;
// }
return false;
}
