I'm working on XPCOM support for Borland Delphi/Object Pascal. Eventually I'd like it to work under Kylix (the Linux version of Delphi) as well. According to a Kylix readme: "Kylix virtual method tables (VMTs) conform to the currently proposed UNIX ABI specification. To make gcc generate conforming VMTs for C++ objects, you must use gcc version 2.95 or later and specify the COM_INTERFACE attribute in the C++ class declaration. Without this attribute, gcc may insert information that changes the VMT offsets and makes Kylix calls to C++ methods fail."
>From reading an earlier thread, I guess the official Mozilla compiler on Linux is egcs-1.1.2? So I'm assuming using VMTs from Kylix won't work, unless I compiled Mozilla myself with gcc 2.95 and I added COM_INTERFACE to nsISupports. (When) Does Mozilla.org plan to switch to gcc 3.x for official builds? Is it correct that the default VMT format in gcc 3.x is equivalent to gcc 2.95+COM_INTERFACE? Tim
