copied!<p><strong>I now have a solution</strong></p> <p>The problem is that when I first tried to switch to <a href="http://en.cppreference.com/w/cpp/utility/functional/bind" rel="nofollow noreferrer"><code>std::bind</code></a> and <a href="http://en.cppreference.com/w/cpp/memory/shared_ptr" rel="nofollow noreferrer"><code>std::shared_ptr</code></a> I was still using the <code>boost::asio::placeholders</code> with <code>std::bind</code>, this resulted in a large amount of template compiler errors, so I then tried to switch piecemeal.</p> <p>I first tried switching just <code>boost::shared_ptr</code> to <code>std::shared_ptr</code>, this failed because <code>boost::bind</code> will not work with <code>std::shared_ptr</code> with out a specialisation of the template <code>get_pointer<typename T></code> for <code>std::shared_ptr</code> (see: <a href="https://stackoverflow.com/questions/4682343/how-to-resolve-conflict-between-boostshared-ptr-and-using-stdshared-ptr">How to resolve conflict between boost::shared_ptr and using std::shared_ptr?</a>). </p> <p>After switching to std::shared_ptr I then switched to <code>std::bind</code>, this time using the <a href="http://en.cppreference.com/w/cpp/utility/functional/placeholders" rel="nofollow noreferrer"><code>std::placeholders</code></a>, (thanks richard) the example code now compiles and works correctly.</p> <p><strong>In order to use <code>std::bind</code> with <code>boost::asio</code> make sure that <code>std::shared_ptr</code> and the <code>std::placeholders</code> are also used.</strong></p>
