Description John L. Poole 2018-02-28 17:12:56 UTC

I have a UEFI based motherboard: https://www.supermicro.com/products/motherboard/ATOM/X10/A1SAi-2750F.cfm
and I am attempting upgrade Xen.  

Building is failing at a stage where binutils squawks and stops the build:

     efi/buildid.o: file not recognized: File format is ambiguous
     efi/buildid.o: matching formats: coff-x86-64 pe-x86-64


When I built this server around December 2016, I ran into this same problem and I consulted the Xen list and learned this may be a bug in binutils.  

See:  https://lists.xenproject.org/archives/html/xen-devel/2016-12/msg00815.html

I worked around this by installing my own binutils forcing it to utilize one of the file formats above or creating my own package, I do not remember.  Since I'm coming onto the problem again more than a year later, I think this may affect anyone else trying to install xen on a UEFI based system.

Unfortunately, my life in the last year has been complicated and I have not been able to keep the server running, so I took it off-line.  Now I am in the process of resurrecting it.  I've updated everything and the only thing left to upgrade is Xen. 

I think this may be a bug better assigned to sys-devel/binutils-2.29.1-r1, but we'll start here.

Your patch attached to #602052 still works as a workaround.

Patch for placement in /etc/portage/patches/app-emulation/xen

This patch is for the /etc/portage/patches/app-emulation/xen approach to patching, whereas my previous patch in Bug #602052 was for the Portage Overlay approach.
