Decompressing a file using boost
I want to decompress a file using boost that has been compressed using bzip2
I tried the following which leads to an error I can not explain
std::stringstream readData(const std::string path) {
std::stringstream myStream;
std::ifstream input(path,std::ios_base::in);
boost::iostreams::filtering_streambuf<boost::iostreams::input>in;
in.push(input);
in.push(boost::iostreams::bzip2_decompressor());
boost::iostreams::copy(in,myStream);
return myStream;
}
I used c++17, boost 1.58 and gcc 8.0 to compile the code above
and get the following error :
terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injectorstd::logic_error >'
what(): chain complete
Would appreciate any help/tips on how to solve this

The device needs to be the last item you push into the filtering_streambuf, after you have pushed a device you aren't allowed to push anything else which is why you are getting the error. See https://www.boost.org/doc/libs/1_68_0/libs/iostreams/doc/classes/filtering_streambuf.html#policy_push
Your code should be:
std::stringstream readData(const std::string path) {
std::stringstream myStream;
std::ifstream input(path,std::ios_base::in);
boost::iostreams::filtering_streambuf<boost::iostreams::input>in;
in.push(boost::iostreams::bzip2_decompressor());
in.push(input);
boost::iostreams::copy(in,myStream);
return myStream;
}
