C++ BOOST undefined reference to `boost::filesystem::detail::copy_file
<p>I have no clue why <code>boost::filesystem::copy_file</code> is making trouble for me.</p>

<pre><code>// g++ -std=c++11 test.cpp -lboost_filesystem -lboost_system -lrt -lboost_wave

#include &lt;boost/filesystem.hpp&gt;

int main()
{

    boost::filesystem::create_directory("aaa");
    // ok


    boost::filesystem::copy_file("f1","f2");
    // /tmp/ccNWZltB.o: In function `boost::filesystem::copy_file(boost::filesystem::path const&amp;, boost::filesystem::path const&amp;)':

    // collect2: error: ld returned 1 exit status


    return 0;
}

<p>I got no inspiration from the source code of boost or its <a href="http://www.boost.org/doc/libs/1_60_0/libs/filesystem/doc/reference.html#copy_file">help</a>:</p>

<pre><code>  inline
  void copy_file(const path&amp; from, const path&amp; to,   // See ticket #2925
                 BOOST_SCOPED_ENUM(copy_option) option, system::error_code&amp; ec)
                                       {detail::copy_file(from, to, option, &amp;ec);}
</code></pre>

<p>Even such a <a href="http://www.richelbilderbeek.nl/CppBoostCopy_file.htm">simple example</a> does not work for me.</p>
