Hello Walter,
So are you saying that XPCOM will work on Linux with D if only the
extern(Windows) was actually extern(C++) ?
Just to make this clear, I'm banking on that the fact that
extern(C++) on an interface should also remove the necessity to alias
to a COM interface on linux. I am guessing that extern(C++) makes a
vtable the same as COM minus the extern(Windows) decoration. If this
is not exactly true, then my hypothesis won't hold. :-)
Neither affects the vtable layout. They affect the calling convention
(register usage, parameter order, stack cleaning, return value).
Okay, I'm confused then. While I understand that the compiler uses
specifically uses extern(...) to describe the calling convention, I
/assumed/ that the compiler was detecting this the extern(C++) like so:
extern (C++)
{
interface D
{
int bar(int i, int j, int k);
}
D getD();
}
And converting what would normal be a D interface (with RTTI reference
in first element of vtable) to a regular vtable compatible with a C++
class type?
How is the vtable made C++ compatible?
You're right, I was wrong.
It looks like all I need to do is change the default linkage inside
IUnknown from Windows to System, as System is implemented as Windows
under windows, and C under linux.
