Я пытаюсь выполнить поиск по каталогу и вывести список всех записей из этого каталога не зависящим от платформы способом.Для этого я попытался использовать std :: filesystem, однако у меня возникают тонны ошибок компиляции при попытке использовать определенные там функции.
Это пример кода, который я пытаюсь запустить (РЕДАКТИРОВАТЬ: Даже если я удаляю цикл for и просто пропускаю 'return 0', я получаю те же ошибки):
#include <iostream>
#include <string>
#include <filesystem>
int main()
{
for (const auto & entry : std::filesystem::directory_iterator("D:\\fac_2ano2semestre"))
std::cout << entry.path() << std::endl;
return 0;
}
Это вывод g ++ --version:
g++.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0

Это пример из моего Makefile (я также пробовал -lstdc ++ fs):
# Compiler
CXX := g++
# Add whatever compiler flags you want.
CXXFLAGS := -std=c++17
CXXFLAGS += -Wall -g
# You MUST keep this for auto-dependency generation.
CXXFLAGS += -MMD
Очень малая часть ошибок, которые я получаю:
g++ -std=c++17 -Wall -g -MMD -c -o src/app.o src/app.cpp
