I really disagree with that. So many devs have already said multiple times in this thread that "-Werror" is only turning existing warnings into fatal errors but "-Werror" itself doesn't add any new checks and more often requires "-O3" to be useful. So let's turn this around: Please show us a *real* case within Gentoo where "-Werror" prevented a real problem which wouldn't otherwise being noticed. E.g. show us a package which was merged on user's system, replacing a working previous version of that package causing *real* problems which could have been prevented if package would have set "-Werror". Unless you can do that we don't really need to discuss this. Simply because everyone interested in "-Werror" *can* set that flag via CFLAGS, even just per package, whereas the majority, not interested in this, cannot do the same to filter "-Werror". Nobody advocating for "-Werror" replied to that fact yet. -- Regards, Thomas Deutschmann / Gentoo Linux Developer C4DD 695F A713 8F24 2AA1 5638 5849 7EE5 1D5D 74A5
