C++ Json library building

Question

I use https://github.com/nlohmann/json to handle in C++, I tried to build a simple code :

#include "lib/json-lib/json.hpp"
using json = nlohmann::json;

int main() {
   json jsonConfiguration;
    while(1){
        std::cout << "Hello Wolrd!" <<std::endl;
    }
    return 0;
}

I take the file json.hpp from https://github.com/nlohmann/json/tree/develop/single_include/nlohmann i saved this one under lib/json-lib. I build my main.cpp with g++ main.cpp and when i launch it after build i got this :

I can only guess what the error message says because it is not in english, but my guess is that you don’t link against the `stdlib` and as of that `std::basic_string` is not known. — t.niese, Mar 07 '19 at 08:02

I use MinGW to build my file.

As you can read here :

If you use MinGW, then copy libstdc++-6.dll and libgcc_s_dw2-1.dll into the same folder as your executable. – salted Sep 2 '17 at 22:44

So i did it and that works well, these files are stored in "/bin"
