Compilation problem with date_time and iostream gzip (and bzip2) filters

26 Aug 2005


      This simple test fails to compile with gcc 4.0.1 (or 4.0.2, it's the
debian unstable version) and boost 1.33.0 if the date_time include is
uncommented.
Is there any known incompatibility between the two libraries ?


#include <boost/iostreams/filtering_stream.hpp>
#include <boost/iostreams/filter/gzip.hpp>

// #include <boost/date_time/local_time/local_time.hpp>

int main()
{
    boost::iostreams::filtering_istream in;
    in.push(boost::iostreams::gzip_compressor());
    return 0;
}
