WARNING: Adding fedora-devel-list to CC.

Hi,
I have been receiving daily emails about linbox and sagemath broken,
but am kind busy lately. I just checked it out, and the root problem
appears to be fflas-ffpack that needs fixing first, then linbox and then
rebuild sagemath.
Actually, I fixed fflas-ffpack in git on Sep 23. The problem is that
"make check" segfaults on ARM, due to the now well-known "atlas
segfaults on ARM" problem. See
https://bugzilla.redhat.com/show_bug.cgi?id=1011648. There has been
no news posted to that bug, nor to fedora-devel-list, so I don't know
who is working on fixing atlas on ARM, nor when we can expect a fixed
build. I see that the maintainer disabled checks for the atlas
package to fool the build system into thinking it had built
successfully. I don't know what the point of that was. It still
leaves packages like fflas-ffpack broken.
Does anybody know what progress is being made towards getting a
working atlas package on ARM? Thanks,

Big thanks to Orion for fixing the atlas build on ARM. Paulo,
fflas-ffpack and linbox have now been rebuilt for the new atlas. You
should be able to rebuild sagemath now. Let me know if you want me to
do the build for you.
Regards,

Thanks!
I started working on updating to sagemath 5.11 but besides the problems
in the update, I was stuck with the fflas-ffpack and linbox issues.
It should be required to review this now:
$ grep -i atlas ~/fedora/sagemath/*
/home/pcpa/fedora/sagemath/sagemath.spec:BuildRequires: atlas-devel
/home/pcpa/fedora/sagemath/sagemath.spec:# ensure proper/preferred
libatlas is in linker path
/home/pcpa/fedora/sagemath/sagemath.spec: perl -pi -e
's|^(extra_link_args = ).*|$1\["-L%{_libdir}/atlas"\]|;'
sage/misc/cython.py
/home/pcpa/fedora/sagemath/sagemath.spec:# o link with proper atlas
/home/pcpa/fedora/sagemath/sagemath.spec: # make atlas/blas
available to compiled sources
/home/pcpa/fedora/sagemath/sagemath.spec: 's|^(extra_link_args
=).*|$1 ["-L%{_libdir}/atlas"]|;' \
/home/pcpa/fedora/sagemath/sagemath.spec: export
LD_LIBRARY_PATH=%{buildroot}%{_libdir}:%{_libdir}/atlas:$LD_LIBRARY_PATH
as rawhide atlas should no longer match the atlas bundled in sagemath.
If you want to look in the above, just check build logs, feel free to
rebuild it, but I am afraid it may not be too easy.
