It's simply the case that I did not have to look into a very similar issue before, so it's new. Thanks! Hans ^ permalink raw reply [flat|nested] 3+ messages in thread

I've tried with a 1.5 weeks old snapshot I had lying about; no "success". But your and my builds are surely quite different anyway. > * Maybe someone has a useful comment for the Debian binutils maintainer > about what's happening in this step of the build? It's xen.efi that's being linked; not sure what else to say. > * Any suggestions about what we can do to help figure this out? I'm pretty certain this needs debugging from the binutils side, so I guess you will want to report it there (even more so with 2.38 around the corner). I guess it's actually debugging ld or bisecting which provide the best chance of figuring out what's going on.

For the sake of xen-devel, this looks to have been fixed in binutils: https://sourceware.org/git/?p=binutils-gdb.git;a=commitdiff;h=07c9f243b3a12cc6749bc02ee7b165859979348b Jan ^ permalink raw reply [flat|nested] 3+ messages in thread
