boost directory_iterator example - how to list directory files not recursive

Question

How should I use directory_iterator to list directory files (not recursive)?

Also what header files / libs should I add/link or other settings I should make? I'm using boost in my project but by some reason directory_iterator is "underclared identifier" while I can use other boost features.

Update

Another solution:

#include <filesystem> #include <boost/filesystem.hpp> #include <iostream>  using namespace boost::filesystem;  for (directory_iterator itr(path_ss); itr!=directory_iterator(); ++itr) {     cout << itr->path().filename() << ' '; // display filename only     if (is_regular_file(itr->status())) cout << " [" << file_size(itr->path()) << ']';     cout << '\n'; }

The tut3 example is what you're looking for:

See it Live on Coliru

Here's a simplified version based on c++11:

Live On Coliru

#include <boost/filesystem.hpp> #include <boost/range/iterator_range.hpp> #include <iostream>  using namespace boost::filesystem;  int main(int argc, char *argv[]) {     path p(argc>1? argv[1] : ".");      if(is_directory(p)) {         std::cout << p << " is a directory containing:\n";          for(auto& entry : boost::make_iterator_range(directory_iterator(p), {}))             std::cout << entry << "\n";     } } 

You can see I linked boost_system (for the errorcode facilities) and boost_filesystem:

g++ -std=c++11 -Os -Wall -pedantic main.cpp -lboost_system -lboost_filesystem && ./a.out . "." is a directory containing: "./main.cpp" "./a.out"

A tested solution:

#include <boost/filesystem.hpp> #include <iterator> #include <iostream> #include <vector>  using namespace boost::filesystem;  int main(int argc, char *argv[]) {     path p(argc>1? argv[1] : ".");     std::vector<directory_entry> v; // To save the file names in a vector.      if(is_directory(p))     {         copy(directory_iterator(p), directory_iterator(), back_inserter(v));         std::cout << p << " is a directory containing:\n";          for ( std::vector<directory_entry>::const_iterator it = v.begin(); it != v.end();  ++ it )         {             std::cout<< (*it).path().string()<<endl;         }         } }
