hi, im trying to interface a cpp class. I'd like to interface a
bigger library and I'm trying to figure out the minimum effort.
--- c++ part:
#include <iostream>
class some_class {
public:
static some_class* __ctor();
some_class();
~some_class();
void some_method();
};
some_class* some_class::__ctor() {
auto thiz = new some_class();
std::cout << "hello from __ctor, thiz:" << thiz << std::endl;
return thiz;
}
some_class::some_class() { std::cout << "some_class constructor,
this:" << this << std::endl; }
some_class::~some_class() { std::cout << "some_class destructor,
this:" << this << std::endl; }
void some_class::some_method() {
std::cout << "some_class some_method, this:" << this <<
std::endl;
}
--- d part:
extern (C++) {
class some_class {
final this();
final ~this();
final void some_method();
}
}
void main() {
some_class someClass = new some_class(); // works, __ctor()
gets called, and it calls the constructor.
someClass.some_method; // works
destroy(someClass); // crashes (SIGSEGV) inside lifetime.d
rt_finalize2()
}

I could do the instancing/destruction by functions and write a
custom d class that calls these methods in this()/~this(). But I
was hoping not needing to write a class in D AND in cpp. and i
was hoping to save another step/level of instancing.
Any idea how to make the destructor of cpp compatible with
"~this()"?
Thx in advance
Markus
