Hello Walter,
So are you saying that XPCOM will work on Linux with D if only the extern(Windows) was actually extern(C++) ?
Yes, I think so. But I should probably test the theory with dmd 2.0 first just to make sure. This is just about over my head since I'm not too familiar with C++ internals. In terms of XPCOM, I believe that when an interface is assigned an implementation pointer and the interface method is called, the most important detail is that the /parameter/ signature at a specific vtable index match that of the implementation's at the same index: that is, the method names are not important except as an alias for client to use; it is assumed that the interface methods will match the calling convention and argument types of the implementation which was assigned to it).
So my question would be, in terms /calling conventions/ in an /interface/ (not a class), does extern(System) differ in any way from extern(C++). Does a "this" pointer get prepended to the argument list of a C++ method call? I apologize if this is an ignorant question. I'm almost clueless here. I'm assuming that the only difference in the extern(C++) is that it:
(1) changes the interface to have a "normal" vtable (as XPCOM needs) and (2) allows for a system calling convention (method name not being important other than that the parameters of interface and implementation match).
