[QUESTION] Return a pointer to object defined by another pybind11 library

[eronconi]

Hi all!

I am trying to accomplish a task similar to the one described by issue #616.

I have developed two independent C++ libraries: libX and libY. Each library has its own separate python3 binding written using pybind11.

ObjX is defined in libX while ObjY is defined in libY. libX includes and dynamically links libY.

ObjX has a method getInternalHandler with the following signature:

ObjY * ObjX::getInternalHandler()

ObjY has no copy constructor and cannot be copied. Is it possible to correctly bind ObjX::getInternalHandler() ?

Thank you all

Solved by using std::shared_ptr<ObjY> instead of raw pointer.

At first it didn't work because libX and libY used a different version of pybind11 (both projects had pybind11 as git submodule, checked out at different commits).

After matching pybind11 versions and switching to smart pointers, it worked out of the box. Great!
