There will be some combinations of gcc and libraries that will produce warnings. It should be easy to turn off -Werror on the make command line if necessary. > So is the proposed situation you don't like, or the path that would be > needed to archieve it? That's OK, but it's doesn't make build system changes unnecessary. The less noisy build system will help find other messages that -Werror won't catch, such as linker warnings. It will help understand what is happening and what is potentially wrong or suboptimal. For example, I'm seeing warnings from xfs.c that nobody is fixing. I can fix the warning by changing the code so that it does exactly what it's doing now but doesn't cause a warning. The problem is, I don't see corresponding structures in the Linux xfs code. I don't have time to investigate xfs implementation to see if I'm possibly hiding a bug. I can imagine that somebody knows more about xfs but doesn't see the warning. Once we make the warning visible, maybe that person will have a look and make a better patch. It's also possible that somebody who want to install GRUB in xfs will be extra cautious when seeing the warning. It's actually a good thing. Sure, not having the warning will be even better. -- Regards, Pavel Roskin _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
