MessageHi, Michael

Looks like you are trying to use Test Execution Monitor. For documentation
check
http://www.boost.org/libs/test/doc/components/test_exec_monitor/index.html

Specifically look on Usage section, tht answer your question in details.

Regards,

Gennadiy

If you are using Test Execution Monitor you dont need to link with above
library, only with one below.
