Decompressing a file using boost

[XPenguen]

Hello,
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(boost::iostreams::bzip2_decompressor());
            in.push(input);
        
            boost::iostreams::copy(in,myStream);
    
            return myStream;
        }

I used c++17, boost 1.58 and gcc 8.0 to compile the code above

The Error I am getting:

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

You should open the file in binary mode, which makes a difference on windows.

// g++ -std=c++11 -Wall -o bzip2test bzip2test.cc -lboost_iostreams

#include <iostream>
#include <fstream>
#include <sstream>
#include <boost/iostreams/filtering_streambuf.hpp>
#include <boost/iostreams/copy.hpp>
#include <boost/iostreams/filter/bzip2.hpp>

std::stringstream readData(const std::string& path) {
    using namespace boost::iostreams;
    std::stringstream ss;
    std::ifstream file(path, file.in | file.binary);
    if (!file) return ss; // or throw an exception or whatever
    filtering_streambuf<input> in;
    in.push(bzip2_decompressor());
    in.push(file);
    copy(in, ss);
    return ss;
}

int main() {
    auto ss = readData("test01.bz2");
    std::cout << ss.str() << '\n';
}
