Seems like it's virtual destructor could that be?
this qt5 binding:
https://github.com/MGWL/QtE5/blob/master/source/qte5.d
seems to always define the constructor.
No, simple virtual (or final) destructor binds just fine with
"~this()" or "final ~this()". "Scalar deleting destructor" is
special thing, afaik, and my C++ knowledge is not enough to
determine why is it required by D side and not required in C++ or
not available in compiled lib.
QtE5, DQml or similar projects mostly wrap cpp-objects - create
them on cpp side with helper function, save returned pointer on d
side and operate via wrapper-functions that call methods on cpp
side. But it looks I should be mostly able to interact with
cpp-defined classes directly now, from 2.081 patchnotes:
"This release also includes ABI fixes where destructors are now
correctly added to the virtual table, and constructor/destructor
calling semantics now match C++. With this, mixed-language class
hierarchies are working, with construction/destruction being
supported in either language."
