[cfe-dev] Linker error with boost::iostreams

[Leszek Świrski]

Hello,

I get a linker error after trying to compile with clang++ a program using 
boost::iostreams. I've reduced the issue to a minimal case, as detailed 
below:

$ cat test.cpp 
#include <boost/iostreams/stream.hpp>
#include <boost/iostreams/device/file.hpp>

int main(void)
{
    namespace io = boost::iostreams;
    io::stream<io::file> test("");
}

$ g++ test.cpp && echo Success 
Success

$ clang++ test.cpp /tmp/cc-fe0zit.o: In function `std::fpos<__mbstate_t> 
boost::iostreams::detail::seek_device_impl<boost::iostreams::streambuf_tag>::seek<std::basic_filebuf<char, 
std::char_traits<char> > >(std::basic_filebuf<char, std::char_traits<char> 
>&, long long, std::_Ios_Seekdir, std::_Ios_Openmode)':

$ clang++ --version
