Thanks Bill, I wasn't happy with my use of either PyCObject_FromVoidPtr or PyArray_BASE. Both are now deprecated. So I updated all the ARGOUTVIEWM_ definitions with %#ifdef SWIGPY_USE_CAPSULE PyObject* cap = PyCapsule_New((void*)(*$1), SWIGPY_CAPSULE_NAME, SWIG_Python_DestroyModule); %#else PyObject* cap = PyCObject_FromVoidPtr((void*)(*$1), SWIG_Python_DestroyModule); %#endif %#if NPY_API_VERSION < 0x00000007 PyArray_BASE(array) = cap; %#else PyArray_SetBaseObject(array,cap); %#endif This could probably be improved with the use of a macro, and checking the returned value of PyArray_SetBaseObject wouldn't hurt either. Anyway, it's a start. Hopefully I haven't messed my use of either SWIGPY_CAPSULE_NAME or SWIG_Python_DestroyModule here. Other changes I made relate to various warnings, in particular relating to the use of SWIG_Python_AppendOutput($result, XXX) where XXX should be a PyObject but was a PyArrayObject. In ARGOUTVIEW / ARGOUTVIEWM typedefs, I made sure there was a PyObject* obj = PyArray_SimpleNewFromData(3, dims, DATA_TYPECODE, (void*)(*$1)); PyArrayObject* array = (PyArrayObject*) obj; which allows me to then use (instead of ,array) $result = SWIG_Python_AppendOutput($result,obj); In the other few other instances where this construct doesn't apply (ARGOUT_ARRAY1 for example) I used typecasting $result = SWIG_Python_AppendOutput($result,(PyObject*)array$argnum); I can't think of anything else at this stage.
