This is how I do it with file_sink:
boost::iostreams::filtering_ostream output_file; output_file.push(boost::iostreams::bzip2_compressor(boost::iostreams::bzip2_params(9))); output_file.push(boost::iostreams::file_sink("file.bz2", std::ios_base::binary)); output_file<<"blalba";
I think if you do just this, nothing happen until output_file is destroyed. So enclose in { }.

Thanks Frederic. However, I think this is not obvious. I would have thought Ken's solution would have worked. I would have also thought mine would have worked until I saw Ken's which indicated std::ios_base::binary was needed when the std::ofstream was created. Is there anywhere in the docs explaining why your method works and Ken's doesn't? -regards, Larry
