Did you link with boost_unit_test framework library? The way above test 
is written requires static library.

Yes BOOST_TEST_MAIN automatically defines test module init function. 
It's intended to be used to automatically registerred test units. Like this:

#define BOOST_TEST_MAIN
#include <boost/test/unit_test.hpp>
BOOST_AUTO_TEST_CASE( free test_function )
{
    BOOST_CHECK( 2 == 1 );
}

You still required to link with the the static library. If you prefer to 
use shared one add #define BOOST_DYN_LINK on top of the test file.

Dynamic library requires slightly different initialization routines. The 
easiest way to avoid this hurdle is to use automated registration like 
in a example above. You can read more about initialization routines and 
Boost.Test usage variants in beta version of new documentation at:
