Confirming that the bug is present and the attached patch works.
Another confirmation that this works. Thanks for the patch! :)
I think this problems also hits me. Is there any progress with this patch ?
works for me, too - but is still not in portage tree :-( needed to do this change manually to the patch file: # diff /usr/portage/dev-games/ogre/files/ogre-1.4.9-as-needed.patch-backup /usr/portage/dev-games/ogre/files/ogre-1.4.9-as-needed.patch 8c8 < + ,-Xlinker --no-as-needed) --- > + ,-Xlinker --no-as-needed -lstdc++)
in portage.
