Dear all, Some compressed data was stored in a vector<char> buf (don't know if it's a right way to store compressed data). I used the "buf" as a source, and tried to add a gzip_decompressor to restore those data. I have tried the following approach, but it doesn't work. vector<char> buf; /* fill in the buf */ namespace io = boost::iostreams; io::filtering_istream in(boost::make_iterator_range(buf)); in.push(io::gzip_decompressor()); What I got is an exception, terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector <std::logic_error>>' what(): chain complete Aborted How can I compose a source which comes from a container, and add a gzip_decompressor to the source? Thanks in advance. Regards, chenwj -- Wei-Jen Chen (陳韋任) Programming Language and System Laboratory (EC131) Department of Computer Science, National Chiao Tung University
