C ++ 17 файловая система, использующая nuwen MinGW в Windows 10

Я хотел попробовать новую библиотеку файловой системы в C ++ 17, поэтому попытался скопировать Пример std :: filesystem :: current_path с сайта cppreference.com и скомпилировать его, используя последнюю версию (16.0) Распределение MinGW от nuwen.net на моей машине Windows 10 x64. Это включает в себя gcc v8.1, который должен поддерживать библиотеку файловой системы в соответствии с Страница поддержки компилятора cppreference.com.

Вот код, который я пытаюсь скомпилировать:

#include <iostream>
#include <filesystem>
namespace fs = std::filesystem;
int main()
{
std::cout << "Current path is " << fs::current_path() << '\n';
}

И команда компилятора, которую я использую:

g++ -std=c++17 filesystem_test.cpp

Вот ошибка, которую я получаю при попытке компиляции:

Заметьте, что мне пришлось отрубить конец сообщения об ошибке, чтобы уменьшить количество символов для этого вопроса. Я поместил полное сообщение об ошибке здесь: https://pastebin.com/pnfMnMs7

Изменить: Согласно комментарию Галика, я попытался изменить мою команду компилятора на

g++ -std=c++17 filesystem_test.cpp -lstdc++fs

Однако я, похоже, получаю точно такую ​​же ошибку, как и раньше
