C++ Boost库iostream:：复制不工作

它说我得到了

boost:：iostreams:：bzip2:：config\u错误

这是否意味着我安装的bzip2过滤器错误

因为我用的东西有些错误

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

int main()
{
    using namespace std;
    using namespace boost::iostreams;

    try {
        ifstream file("hello.bz2", ios_base::in | ios_base::binary);
        filtering_streambuf<input> in;
        in.push(bzip2_decompressor());
        in.push(file);
        boost::iostreams::copy(in, cout);
    }
    catch(const bzip2_error& exception) {
        int error = exception.error();

        if(error == boost::iostreams::bzip2::data_error) {
            // compressed data stream is corrupted
            cout << "compressed data stream is corrupted";
        }
        else if(error == boost::iostreams::bzip2::data_error_magic)
        {
            // compressed data stream does not begin with the 'magic' sequence 'B' 'Z' 'h'
            cout << "compressed data stream does not begin with the 'magic' sequence 'B' 'Z' 'h'";
        }
        else if(boost::iostreams::bzip2::config_error) {
            // libbzip2 has been improperly configured for the current platform
            cout << "libbzip2 has been improperly configured for the current platform";
        }
    }
}

我得到：
