[Boost-users] Overloading errors

Does anyone know why the following sample fails (it was adapted from the boost overloading example) and how to do this correctly. Thanks in advance. #include #include #include #include #include #include #include using namespace boost::python; struct X {     int f(int x, double y = 4.25, char const* z = "wow")     {         return x;     }     int f(int x, bool b = true) {         return x;     } }; BOOST_PYTHON_MEMBER_FUNCTION_OVERLOADS(f_member_overloads, X::f, 1, 3) BOOST_PYTHON_MODULE(args_ext) {     class_<X>("X", "This is X's docstring")         .def("f1", &X::f,              f_member_overloads(args("x", "y", "z"), "f's docstring"                                 )[return_internal_reference<>()]              )         ; } g++ -fpic -shared -o test.so test.cpp -lpython2.4 -lboost_python -I/usr/include/python2.4 test.cpp: In function ‘void init_module_args_ext()’: test.cpp:31: error: no matching function for call to ‘boost::python::class_::def(const char [3], <unresolved overloaded function type>, boost::python::detail::overloads_proxy, f_member_overloads>)’
