Description

learning from:
http://www.boost.org/doc/libs/1_43_0/libs/filesystem/doc/index.htm

#include "boost/filesystem.hpp"   // includes all needed Boost.Filesystem declarations
#include <iostream>               // for std::cout
using boost::filesystem;          // for ease of tutorial presentation;
                                  //  a namespace alias is preferred practice in real code

compiling gives me this error:

boost_example.cpp:3: error: namespace ‘boost::filesystem’ not allowed in using-declaration
