title: Boost-log linker error
body: <p>i've downloaded and builded Boost 1.55 from source. I'm trying to use Boost-log. In basic case (<a href="http://boost-log.sourceforge.net/libs/log/doc/html)/log/tutorial.html#log.tutorial.trivial" rel="nofollow">http://boost-log.sourceforge.net/libs/log/doc/html)/log/tutorial.html#log.tutorial.trivial</a> it's working fine without any problems, but when i try to use some more advanced features(like this - <a href="http://boost-log.sourceforge.net/libs/log/example/doc/tutorial_fmt_stream.cpp" rel="nofollow">http://boost-log.sourceforge.net/libs/log/example/doc/tutorial_fmt_stream.cpp</a> ) i'm getting this error:</p>

  <p>So basically it can't find functions convert(...), code_convert(...) and codecvt(...) in .lib files.  </p>
  
  <p>I've already tried to add all release libraries (.lib files made while building boost) to "additional libraries" and generally i think that visual studio find all libraries, but can't find those functions in libraries. Any ideas how can i fix this?</p>
  
  <p>I've build Boost 1.55 from source using visual studio 2010 (msvc10.0), 32 bit, release and debug. I'm working on windows 7 x64.</p>
