#include <iostream>
#include <filesystem>
#include <fstream>
namespace fs = std::filesystem;
int main()
{
fs::create_directory("dir_a");
std::ofstream{"dir_a/a.txt"};
fs::create_directory("dir_b");
std::ofstream{"dir_b/b.txt"};
fs::create_directory_symlink("dir_a", "dir_b/dir_a");
for (const fs::directory_entry& x : fs::recursive_directory_iterator(
"dir_b",
fs::directory_options::follow_directory_symlink)) {
std::cout << x.path() << std::endl;
}
}
expected result:
"dir_b/b.txt"
"dir_b/dir_a"
"dir_b/dir_a/a.txt"
actual result:
"dir_b/b.txt"
"dir_b/dir_a"
terminating with uncaught exception of type
std::__1::__fs::filesystem::filesystem_error: filesystem error: in
recursive_directory_iterator::operator++(): attempting recursion into
"dir_b/dir_a": Too many levels of symbolic links
