Hello, you're receiving this canned bug because the package in summary uses the flag -Werror during build, which transforms warnings in errors, and is prone to break software when new GCC releases are added to Gentoo. Please make sure your package does not use -Werror during build, so that it can be more future-proof for the new GCC releases. Thanks, Diego
Created attachment 201727 [details, diff] removes all werrors I believe that this patch should be applied against the xen package and the xen-tools package. It applies cleanly against xen-tools-3.4.1, I haven't had time to check it against anything else. I think that tools/ioemu-qemu-xen/configure will not enable -Werror by default. In fact, that configure file is an example of how xen should handle -Werror. The reason to try to remove -Werror from packages is to prevent potentially avoidable Gentoo bugs from being filed. The following is an example of such a bug that would be filed: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1427 . While this bug is probably something that should be fixed in the xen source, most of these warnings can be safely ignored.
Xen 4.1 in tree. Please test with it and reopen if it doesnt work
