cursorCreateFromFile requires wxc's Cursor_CreateFromImage functions.
http://darcs.haskell.org/wxhaskell/wxcore/src/Graphics/UI/WXCore/Image.hs

And wxhaskell doesn't have statically information now.
http://www.mail-archive.com/wxh...@li.../msg00196.html


So I think below change is better than hiding functions and references.

EWXWEXPORT(void*, Cursor_CreateFromImage)(wxImage* image)
{
#ifndef __WXGTK__
	return (void*) new wxCursor(*image);
#else
   return NULL;
#endif
}

This solution is usually used when wxc requires compilation flag.

Hmm ... How about clean your wxhaskell's working directory.
It seems that your wxhaskell uses old wxcore/src/Graphics/UI/WXCore/WxcClassesAL.hs.
