Those errors are pretty much unrelated to the warnings you posted
(but the warnings give a clue! - see below). Code in your dll
certainly should not define _IMPL_NS_COM. This is only to be
defined in compiling the code that goes in the xpcom dll.
I can solve your problem for you...
If you look close at the warnings and these errors for the
methods that appear in both lists you'll see that the method
signatures do not match exactly. In one set you see 'int' where
you see 'long' in the other set. These correspond to nsrefcnt
typed params. Look at -
http://lxr.mozilla.org/seamonkey/source/xpcom/base/nsISupportsUtils.h#68
- and you'll see the #ifdefs that control this type - either int
or long. I'd have to guess that you are not #define'ing XP_WIN in
one of your build projects. The OS/2 people have been mucking
with XP_PC/XP_WIN/XP_OS2 flags in the tree and stuff outside the
mozilla tree has been getting burned here and there. Jon Smirl
has been asking and not been getting answered about a correct way
to detect this mistake.
Lack of XP_WIN is also causing the GetWeakReference problem. It
is suspicious that it shows as __thiscall - this is an interface
method and it should be __stdcall. This implies that NS_IMETHOD
macros are not expanding to the right thing. Same problem.
I'd fix the XP_WIN issue in your makefiles and do a full clobber
build of xpcom and your dll and see where it goes.
