Interesting. Because I'm finding the following:
I know docs are not ideal but this part is very clear I thought. test_exec_monitor is an old alternative t ounit test framework, which is long deprecated and they definitely do not require each other

How do you use Boost.Test? Automated test unit registration? Are you sure you've defined BOOST_TEST_MODULE/BOOST_TEST_MAIN? Gennadiy

There are several ways you can get an appropriate implementation of main() from Boost.Test. Since you are using the dynamic library version of Boost.Test, you need at most one source file that defines BOOST_TEST_MAIN before including <boost/test/unit_test.hpp>. (You should also be defining BOOST_TEST_DYN_LINK before including unit_test.hpp in all your source files since you are using the dynamically linked library.) -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
