MinGW 上 C++17 的编译错误<filesystem>

我想尝试使用现在与 C++17 标准分开的新filesystem库，但我无法编译东西。

我已经尝试过的事情：

• 将 MinGW 更新到 8.2.0
• 使用g++ -std=c++17 test.cpp -o test编译
• 将-lstdc++fs添加到编译中(这不起作用，我收到错误c:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: cannot find -lstdc++fs (
• 使用<filesystem>和<experimentalfilesystem>

这是我的简单测试代码，只是为了尝试编译：

#include <iostream>
#include <filesystem>
using namespace std;
int main(int argc, char* argv[]) {
  return 0;
}

并与g++ -std=c++17 test.cpp -o test一起编译

有了这个，我得到错误：

In file included from c:mingwlibgccmingw328.2.0includec++filesystem:37,
                 from test.cpp:2:

                 from test.cpp:1:

。还有更多错误...

c:mingwlibgccmingw328.2.0includec++bitsfs_path.h:603:7: note: suggested alternative: 'string_view'
       string_type __tmp;
       ^~~~~~~~~~~

       if (__str_codecvt_in(__first, __last, __tmp, __cvt))

还有其他人有什么建议吗？似乎大多数人都在通过在编译中添加-lstdc++fs来解决这个问题，但就像我说的，这对我不起作用。

谢谢！
