maybe these patches could help https://src.fedoraproject.org/rpms/xen/blob/master/f/xen.gcc8.fix.patch https://src.fedoraproject.org/rpms/xen/blob/master/f/xen.gcc8.temp.fix.patch
I am not a developer, unfortunately I do not know how to apply patches. Maybe you could test it and merge to Gentoo repo if it fixes?
(In reply to spargeltarzan from comment #4) > I am not a developer, unfortunately I do not know how to apply patches. In that case, it's probably not wise to run a hard masked gcc :) Please read below how to apply additional patches to packages: https://wiki.gentoo.org/wiki//etc/portage/patches
Let me rephrase it a bit, I am a studied in informatics, but I do not work as a software engineer. For Gentoo I see myself between an user and a developer and someone who tries things, discovers bugs and helps how I might can to fix it. Once we have xen fixed with gcc 8.1, every user will benefit when gcc 8.1 will be in ~amd64. I will work through the patching section of the wiki and let you know my results. For Xen I observed in the last year, that with every new Gcc release emerge fails. Maybe we discover a root cause and we can fix in long-term.
Well, each gcc upgrade resulted in xen code change that needed to be merged upstream. I think there is nothing we (as the distro) can do about it to prevent such situation. That's why we have a testing/stable version of xen and the testing is expected to be broken from time to time (for example when we test with gcc 8, but none of the xen developers actually use gcc 8). Of course providing such test results is appreciated and providing tested patches that fix the problem are very welcomed.
Are you sure the provided patch is made for xen-tools? Looks like it might be for xen, what compiles successfully with gcc 8.1 ebuild preparing fails with the applied patches. In xen-dev mailing lists I see some hints that some use gcc 8.1, but I don't find compilation issues or possible solutions.
Xen 4.10.1 is available, if you merg it to Gentoo repo I will appreciate and test it.
https://www.mail-archive.com/xen-devel@lists.xenproject.org/msg14111.html shows the hint the xen developers only face some warnings on gcc 8.1
I've a work-in-progress in my overlay: https://github.com/hydrapolic/gentoo/tree/master/app-emulation/xen https://github.com/hydrapolic/gentoo/tree/master/app-emulation/xen-tools Currently shim is disabled (by a patch) as it fails to compile on my machine.
