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 << '
';
}

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:
";

        for(auto& entry : boost::make_iterator_range(directory_iterator(p), {}))
            std::cout << entry << "
";
    }
}

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"
