Re: [Boost-users] bzip2_compressor help

           namespace BI = boost::iostreams;            BI::filtering_ostream out;            std::fstream mfile("test.gz", std::ios::binary|std::ios::out);            out.push(BI::bzip2_compressor());            out.push(mfile);            out << "This is a gz file" << endl;

Maybe you should replace fstream by BI::file_sink? but note that the file is closed (and fully written) only when the variable out is destroyed so that you need to enclose your code in { ... } if you need to use the file just after out <<...<< endl; Frédéric
