Using msvc 8 I am having a link issue with the following
code snippet. Commenting out the line with blog::keywords::format
will cause the link error to go away.

---------------------------------------------------
#include <iostream>

#include <boost/log/attributes.hpp>
#include <boost/log/common.hpp>
#include <boost/log/core.hpp>
#include <boost/log/exceptions.hpp>
#include <boost/log/filters.hpp>
#include <boost/log/formatters.hpp>
#include <boost/log/sinks.hpp>
#include <boost/log/trivial.hpp>

#include <boost/log/utility/init/to_file.hpp>
#include <boost/log/utility/init/common_attributes.hpp>

namespace blog = boost::log ;

int main()
{
   blog::init_log_to_file( blog::keywords::file_name = "foo_%N.log",
                           blog::keywords::rotation_size = 10 * 1024 * 1024,
                           blog::keywords::format = "[%TimeStamp%]: %_%",
                           blog::keywords::open_mode = std::ios_base::app  );

   BOOST_LOG_TRIVIAL(trace) << "A trace severity message";

   return 0;
}
------------------------------------------------------

Any ideas?
