I found an old thread [1] from 2007where it is advised to use the following combination if one wants to use dynamic linking and manual registration: If you insist on combination of manual registration with shared library, it should look like this: int main( int argc, char* argv[] ) { return ::boost::unit_test::unit_test_main( &init_unit_test, argc, argv ); } Is this still the way to do it? I tried to apply the technique as follows: #define BOOST_TEST_DYN_LINK #define BOOST_TEST_ALTERNATIVE_INIT_API #include <boost/test/unit_test.hpp> void test() { } bool init_unit_test() { boost::unit_test::test_suite* ts = BOOST_TEST_SUITE("test suite"); ts->add(BOOST_TEST_CASE(&test)); boost::unit_test::framework::master_test_suite().add(ts); return true; } int main(int argc, char* argv[]) { return ::boost::unit_test::unit_test_main(&init_unit_test, argc, argv); } That, however, gives me the following run-time error: Running Test setup error: signal: SIGABRT (application abort requested) Any help would is appreciated.
