Hi Sam,
I don't know whether the files were ever submitted upstream. The files date from 2002. HP stopped
supporting PA-RISC work at Redhat somewhere around that time.
Anyway, the errors don't look hard to fix. Do you want to take a crack at a patch?
Regards,
Dave

HI,
I'm not a Debian user but Gentoo (from where I hail) is the only other distro AFAIK still supporting HPPA, so I like
to look at what Debian is doing for some packages.
I noticed elfutils upstream lacks HPPA support but saw Debian has a HPPA backend patch [0].
Two questions:
1. Has this been attempted to be upstreamed before? Any known problems with it?
2. I'm not sure it's actually being used in Debian despite being applied(?)
The backends/Makefile.am changes seem to be missing a hunk(?):

Without adding this to a local build in Gentoo, the PARISC files added by the patch
aren't built at all.
I don't see any reference to the files in the build log for Debian either [1].
But when I add this t Makefile.am anyway, I end up with a build failure:
