Red Hat Bugzilla – Bug 1303265
On arm _gnu is no longer -gnuabi
Last modified: 2016-02-04 18:22:57 EST
The _gnu macro which should be predefined by rpm has changed during the last 24 hours or so on arm, previously it has been -gnuabi, now it is just -gnu.
still shows a successful build with -gnuabi, while
from about 25 hours later already has -gnu, which of course breaks the build, on arm if the target triplet does not end with -gnueabi, it is considered to be the old ABI which is no longer supported.
For now I've worked around this bug by defining
%global _gnu -gnueabi
myself, but this is going to break lots of things.
Is the _gnu macro predefined by rpm program/library, or comes from the rpm invocation (i.e. it might be also some rel-eng issue), or from macros, somewhere else?
this will block the mass rebuild.
/usr/lib/rpm/platform/*/macros (part of rpm package) define _gnu
Those files have -gnu instead of -gnueabi even on F22, and from what I've tried, f23 (and f24 until very recently) worked fine in koji. So it must be something different (overridden from rpm binary, or from mock/koji/whatever).
I would add this bug as reference:
Basically mock in the fedora infra is configured to use "mockhost=redhat-linux-gnu" everywhere. So no matters which arch it is, it's using -gnu suffix everywhere. armv7hl should stands for new ABI that alone from what I've understood.
Sadly, arm is an exception here, it really has to use gnueabi, otherwise config.guess/config.sub, lots of autotools etc. will get things wrong.
This was caused by a change in rpm. It will be fixed in rpm-4.13.0-0.rc1.21.fc24
In fc23 branch fixed in rpm-4.13.0-0.rc1.11.fc23.
