Bug 1116767

I couldn't find out why it was not built on ARM.  The only build
failures visible in Koji are for x86_64.

http://koji.fedoraproject.org/koji/packageinfo?packageID=10264

(However that doesn't exclude the possibility that Keith saw a
scratch or local build failure on ARM).

I have just started a scratch build with ARM reenabled to see
if it would work:

http://koji.fedoraproject.org/koji/taskinfo?taskID=7111419

Here is the failure:

ceph-0.81.0-2.fc21 built fine on armv7hl as part of the mass rebuild

http://koji.fedoraproject.org/koji/buildinfo?buildID=524063

This indicates changes in the .spec and hence the build process has changed and broken this, we're seeing similar issues with aarch64, not sure about other secondary packages

Also this package builds fine for me on my F20 ARM machine.

Possibly some change in glibc in F21?

Putting priority back to urgent. Dropping an architecture with no prior warning which affects multiple downstream packages is *not* a 'low' priority issue.

This is not a low priority. ARMv7 is a primary architecture and this breaks numerous functionality on arm

By the way, the build failure on ARM appears to have been caused
by removing this section (from %build) when moving to the new spec file:

%ifarch %{arm}
# libatomic_ops seems to fallback on some pthread implementation on ARM
EXTRA_LDFLAGS="-lpthread"
%endif

So it's likely (I am still testing) that simply adding that back
into %build should fix the ARM build.  Will let you know for sure
once my very slow ARM server finishes (fast one just died :-( ).

Created attachment 916189 [details]
arm.patch

Builds when the attached patch is added.

(Note this is a patch against the new / upstream ceph.spec.  I notice
that the current spec file is back to the old one).

Spec was reverted and a new build pushed, so this is currently fixed.
