The configure logs show checking whether C compiler handles -Wsuggest-attribute=const... yes checking whether C compiler handles -Wsuggest-attribute=format... no checking whether C compiler handles -Wsuggest-attribute=noreturn... yes checking whether C compiler handles -Wsuggest-attribute=pure... yes So, can someone with a Debian machine check if it helps to modify _Pragma ("GCC diagnostic ignored \"-Wsuggest-attribute=format\"") To be just _Pragma ("GCC diagnostic ignored \"-Wsuggest-attribute\"") THough, I guess some very old gcc might not support -Wsuggest-attribute at all, so perhaps we need to check this fully Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
