Created attachment 432020 [details, diff] Patch to fix compile failure (part 1) I'm betting this got pulled in by one of the other headers. It will break in libxl after this. I'll post a patch shortly that fixes both.
Created attachment 432022 [details, diff] Fixes build This may be tied to or dependent on specific klibc changes, and I have not tested whether it's functional, but it builds with this patch.
This only fixes system-qemu builds. Will post a v3 with fixes for non system-qemu.
Created attachment 432036 [details, diff] Fixes build v3 tested with and without system-qemu. There are certainly other use combinations that will trigger this failure. One of the headers used to include the major/minor/makedev macros, which live in sys/sysmacros.h Verified working on at least pvhvm linux guests, all are probably fine if the build finishes.
Also, (for those that may come across this), my fix is almost definitely not correct, it's just what I needed to make it work on my system. The fact that a newer klibc broke xen-tools after 4? years of it being fine leads me to believe that it's a klibc bug and not a xen-tools bug.
so how do you CC for dev-libs/klibc; maintainers: (none)?? base-system?
This bug seems to have crept back in in xen-tools 4.8.1-r1. Old patch no longer cleanly applies, but it's pretty obvious to figure out how to re-add these.
The patch is included for 4.8.2.
