I'm trying to register some user exceptions on the unit_test framework so I did the following: #include using boost::unit_test::register_exception_translator; . . . void translate_InvalidInterval(const Interval::InvalidInterval& e) { } void translate_NotIntercept(const Interval::NotIntercept& e) { } interval_test_suite::interval_test_suite() : test_suite ("interval_test_suite") { boost::unit_test::register_exception_translatorInterval::InvalidInterval (translate_InvalidInterval); boost::unit_test::register_exception_translator< Interval::NotIntercept> (translate_NotIntercept); . . . } I get the following compile error: error: 'boost::unit_test::register_exception_translator' has not been declared I tried to grep all .hpp files on /boost/test to find if some of them have this function. The only one (execution_monitor.hpp) I found has it as part of a class. I was expecting it as a template function in the framework. So, how what do I have to include to make this work?
