Namely does not 1) compile with std::wstring (see example 1 below) 2) link with wchar_t* (see example 2 below) arguments on windows platform with official boost dlls. Some analysis from my side. Could not test static libraries, as could not figure out how to link against official static libs. I was able to build static boost test lib manually as described at http://www.boost.org/doc/libs/1_65_1/libs/test/doc/html/boost_test/adv_scenarios/static_lib_customizations/entry_point.html. I.e. b2 --with-test link=static define=BOOST_TEST_NO_MAIN define=BOOST_TEST_ALTERNATIVE_INIT_API and make BOOST_REQUIRE_EQUAL to accept wchar_t. See example 3 below. Unfortunately example 3 did not compile with official binaries (?!) boost::test_tools::tt_detail::equal_impl(wchar_t const *,wchar_t const *) is lost in dlls, but available in static lib. In boost_1_54_0-msvc-11.0-32.exe however, equal_impl(wchar_t const *,wchar_t const *) is available in boost_unit_test_framework-vc110-1_54.dll. --- Example 1 --- {{{ #include #include #include #define BOOST_TEST_MODULE test_module_name #define BOOST_TEST_DYN_LINK #define BOOST_TEST_NO_MAIN #include BOOST_AUTO_TEST_SUITE( boost_my_test ); BOOST_AUTO_TEST_CASE(boost_my_test_1) { std::wstring v1(L""a""); std::wstring v2(L""a""); BOOST_REQUIRE_EQUAL(v1, v2); } BOOST_AUTO_TEST_SUITE_END(); int main(int argc, char* argv[], char* envp[]) { return boost::unit_test::unit_test_main( &init_unit_test, argc, argv ); } }}} Error: {{{ D:\LIBS\boost\boost-1_65_1\boost/test/tools/detail/print_helper.hpp(52): error C2338: Type has to implement operator<< to be printable D:\LIBS\boost\boost-1_65_1\boost/test/tools/detail/print_helper.hpp(61): note: see reference to function template instantiation 'std::ostream &boost::test_tools::tt_detail::impl::boost_test_print_type(std::ostream &,const T &)' being compiled with [ R=std::wstring, T=std::wstring ] }}} --- Example 2 --- {{{ #include #include #include #define BOOST_TEST_MODULE test_module_name #define BOOST_TEST_DYN_LINK #define BOOST_TEST_NO_MAIN #include BOOST_AUTO_TEST_SUITE( boost_my_test ); BOOST_AUTO_TEST_CASE(boost_my_test_1) { const wchar_t* v1 = L""a""; const wchar_t* v2 = L""a""; BOOST_REQUIRE_EQUAL(v1, v2); } BOOST_AUTO_TEST_SUITE_END(); int main(int argc, char* argv[], char* envp[]) { return boost::unit_test::unit_test_main( &init_unit_test, argc, argv ); } }}} Error: {{{ error LNK2001: unresolved external symbol ""__declspec(dllimport) class boost::test_tools::assertion_result __cdecl boost::test_tools::tt_detail::equal_impl(wchar_t const *,wchar_t const *)"" (__imp_?equal_impl@tt_detail@test_tools@boost@@YA?AVassertion_result@23@PB_W0@Z) }}} -- Example 3 -- {{{ #include #include #include #define BOOST_TEST_MODULE test_module_name #define BOOST_TEST_NO_MAIN #define BOOST_TEST_ALTERNATIVE_INIT_API #include BOOST_AUTO_TEST_SUITE( boost_my_test ); BOOST_AUTO_TEST_CASE(boost_my_test_1) { const wchar_t* v1 = L""a""; const wchar_t* v2 = L""a""; BOOST_REQUIRE_EQUAL(v1, v2); } BOOST_AUTO_TEST_SUITE_END(); int main(int argc, char* argv[], char* envp[]) { return boost::unit_test::unit_test_main(init_unit_test, argc, argv); } }}}" Bugs new To Be Determined test Boost 1.65.0 Problem
