Hi, I have a class with a generic constructor as follows : class X { indexes m_idx; template<class strategy> X(){ build_indexes<strategy>() };
My problem is that I am not able to figure out the syntax to export this constructor. Is the above class not well defined ?.
That's a good question. I'm not sure if it's possible using boost::python::init, but here's a possible workaround: namespace bp = boost::python; template <typename strategy> static X construct_X() { // could also return registered smart pointer to X. return X<strategy>(); } BOOST_PYTHON_MODULE(example) { bp::class_<X>("X", bp::no_init) // no_init keeps bp from trying to call default ctor .def("__init__", bp::make_constructor(&construct_X<concrete_strategy>)) ; } I haven't tested that, but I think it should work. By the way, you'll get more responses to Boost.Python questions at the Python/C++-sig mailing list: cplusplus-sig@python.org Hope that helps! Jim Bosch
