Code fails to compile when binding the std::deque of Non copy/move-constructible elements (similar to #487)

[ashhasthantra]

I see that there was an issue #487 which was supposedly fixed by #490. My code fails compilation with an error "use of deleted function" when binding the std::deque containing non copy/move-constructible elements.
Is there a fix for this issue? I couldn't find the changes which #490 claims. I am checked in master branch of pybind11 and I still get the same error.

@ashhasthantra What version of pybind11 are you on? What code did you try compiling?

I just tried this, and this works for me, so I can't reproduce your error:

#include <pybind11/pybind11.h>
#include <pybind11/stl_bind.h>

#include <deque>

namespace py = pybind11;

class X {
public:
        X(int i) : m_i(i) {}
        X(const X&) = delete;
        X(X&&) = default;
        ~X() = default;

        int get_i() { return m_i; }

private:
        int m_i;
};

PYBIND11_MODULE(example, m) {
        py::class_<X>(m, "X")
                .def(py::init<int>())
                .def("get_i", &X::get_i);
        py::bind_vector<std::vector<X>>(m, "VectorX");
        py::bind_vector<std::deque<X>>(m, "DequeX");
}

Please reopen if updating to pybind11 2.5.0 doesn't solve your problem!
