My application compiles but the screen is full of these messages while compiling. They don't occur when wxwidgets is compiled with gtk.
/usr/include/wx-3.0-X11/wx/univ/window.h:18:28: warning: attribute ignored in declaration of 'class wxControlRenderer' [-Wattributes]
class WXDLLIMPEXP_FWD_CORE wxControlRenderer;
Googling about it seems that there are harmless but annoying. Is there a compiler option to stop this? I thought of patching WXDLLIMPEXP_FWD_CORE out but it seemed risky. I've got to say that everytime I look at the source code I feel like I'm descending into macro hell.
