如何解决“严重错误:文件系统:没有这样的文件或目录"在Code :: Blocks中? [英] How to fix "fatal error: filesystem: No such file or directory" in Code::Blocks?

问题描述

我正在编写一个删除旧备份文件的脚本.我已经像平常一样包含了文件系统"，但是这次，我得到了这个错误:致命错误:文件系统:没有这样的文件或目录"

I'm writing a script which deletes old backup files. I've included "filesystem" as I would normally do, but this time, I got this error: "fatal error: filesystem: No such file or directory"

我尝试包括"experimental/filesystem"，并将"-lstdc ++ fs"设置为GCC标志.什么都没有为我工作.

I tried to include "experimental/filesystem" and I set "-lstdc++fs" as GCC flag. Nothing has worked for me.

#include <cstdlib>
#include <algorithm>
#include <vector>
#include <filesystem>

namespace fs = std::filesystem;

int main()
{
    fs::path const directory{ "C:\Test" };
    std::vector<fs::directory_entry>::size_type const num_files_to_keep{ 5 };

推荐答案

使用CodeBlocks ang GCC 8.0或更高版本您需要设置c ++ 17编译器选项 (我在上次Nightly版本中使用CodeBlock).

然后，必须将stdc++fs库添加到链接器设置选项.

Using CodeBlocks ang GCC 8.0 or above You need to set c++17 compiler option (I'm using CodeBlock last Nightly build).

Then you must add to the Linker settings options the stdc++fs library.

然后必须添加GCC 8.0中的#include <filesystem>指令，而不是<experimental/filesystem>
在Windows上，目录分隔符为\\(两个反斜杠).
您需要编写:

And then you must add the #include <filesystem> directive, from GCC 8.0, and not <experimental/filesystem>
On windows the directory separator is \\ (two backslash).
You need to write:

fs::path const directory { "C:\\Test" };
