Comment (by Mukkarum.Amin_at_[hidden]):

 Replying to [ticket:1727 Mukkarum.Amin_at_[hidden]]:
 > The example code at the very end of this
 [http://www.boost.org/libs/iostreams/doc/classes/bzip2.html] page which
 decompresses data from a file and writes it to standard out is erroneous
 and does not compile. The boost::iostream namespace is not specified. The
 code should be as follows, I have verified that it compiles and runs
 properly:
 > {{{
 > int main(int argc, char** argv)
 > {
 >   using namespace std;
 >   using namespace boost::iostreams;
 >
 >   ifstream file("hello.bz2", ios_base::in | ios_base::binary);
 >   filtering_streambuf<input> in;
 >   in.push(bzip2_decompressor());
 >   in.push(file);
 >   copy(in, cout);
 >   return 0;
 > }
 > }}}

 Forgot to add includes here is the complete code with includes:
 {{{
 #include <fstream>
 #include <iostream>
 #include <boost/iostreams/filtering_streambuf.hpp>
 #include <boost/iostreams/copy.hpp>
 #include <boost/iostreams/filter/bzip2.hpp>

 int main(int argc, char** argv)
 {
   using namespace std;
   using namespace boost::iostreams;

   ifstream file("hello.bz2", ios_base::in | ios_base::binary);
   filtering_streambuf<input> in;
   in.push(bzip2_decompressor());
   in.push(file);
   copy(in, cout);
   return 0;
 }
 }}}
