--- Comment #12 from Jonathan Wakely <redi at gcc dot gnu.org> 2011-10-19 16:58:05 UTC --- (In reply to comment #11) > it will be possible to add better waring/error in this case? Not easily, the error you get is from the linker. This has been discussed MANY times in other bugzilla reports, search for PRs with status=RESOLVED and the words "static const undefined reference" > maybe some info when you try take ref from const static objects? No, because there is nothing wrong with doing that as long as you have a definition for the member. I do not want the compiler to complain when I write correct code just to remind people who write incorrect code not to forget something.
