[Boost-users] boost zlib problem on linux (works fine on windows)

[ChristinaDRS]

Hello all,

This code works fine on Windows, but I get the exception when running in
linux.. any ideas why? The code, how its compiled, and error are below:

#include <iostream>
#include <sstream>
#include <boost/iostreams/copy.hpp>
#include <boost/iostreams/device/back_inserter.hpp>
#include <boost/iostreams/filter/bzip2.hpp>
#include <boost/iostreams/filter/zlib.hpp>
#include <boost/iostreams/filtering_stream.hpp>
using namespace std;

int main()
{
string message = "this is a test message!";
cout << "message: " << message << endl;
string compressed;
boost::iostreams::filtering_streambuf<boost::iostreams::output> out;
out.push(boost::iostreams::zlib_compressor());
out.push(boost::iostreams::back_inserter(compressed));
boost::iostreams::copy(boost::make_iterator_range(message), out);
cout << "compressed message: " << compressed << endl;

boost::iostreams::filtering_streambuf<boost::iostreams::input> in;
in.push(boost::iostreams::zlib_decompressor());
in.push(boost::make_iterator_range(compressed));
string decompressed;
boost::iostreams::copy(in,
boost::iostreams::back_inserter(decompressed));
cout << "decompressed message: " << decompressed << endl;
}

# g++ zlib.cpp zlib_test2.cpp -o zlib_test2 -lz
# ./zlib_test2
message: this is a test message!
compressed message:
terminate called after throwing an instance of
'boost::iostreams::zlib_error'
what(): zlib error
Aborted
#

Thanks!
Christina

Try calling flush on the streambuf.
