Summary: 2.4 compatibility fails due to missing wxAppConsole symbols

Initial Comment:
Building wxMac 2.8.7 on Mac OS X 10.4.11 (similar to how macports does but with 2.4 compatibility and xrc enabled) failed because the 2.4 compatibility ifdef was being handled incorrectly. The linker expected the symbols to be there (so someone including app.h had already included setup.h) but appbase.cpp did not include setup.h - hence the compatibility define was not set - and so the symbols weren't built.

I'd suspect the best fix would be to add #include "wx/setup.h" to app.h but perhaps just adding it to appbase.cpp would be enough.

Strange, these functions should be defined in monodll_appbase.o -- could
you please check with nm or otool if this is the case?

As for setup.h, it's always included so this is definitely not the
problem. And it almost certainly doesn't have anything to do with XRC.

BTW, why do you build in monolithic mode?

Here's the configure line (enabling 2.4 compatibility and xrc):

../wxMac-2.8.7/configure --mandir=/opt/local/share/man
--with-libiconv-prefix=/opt/local --with-libjpeg --with-libtiff
--with-libpng --with-zlib --with-sdl --with-opengl --with-mac
--disable-sdltest --enable-unicode --enable-display --enable-monolithic
--enable-compat24 --enable-xrc

Hmm... Looks like the XRC lib doesn't like the compatibility define.

And the errors you get are...?

I added my first suggestion but it didn't work. I'm currently building
with the compatibility ifdef commented out (ie. forced on) to see if that
will work. Commenting out just the .cpp file causes the symbols to be found
but vtable entries for them are not.
