Description Bernhard Wiedemann 2023-12-02 05:49:44 UTC

While working on reproducible builds for ALP+openSUSE, I found that
our colord package varied from differences in .icc files caused by differences in build machine CPU capabilities (probably AVX) 

Also filed upstream at https://github.com/omgovich/colord/issues/122 but they seem inactive.
You find a reproducer and more details there.

Reproducer with osc:
Run on a host that has output from  lscpu|grep avx

for cpu in qemu64 host ; do 
  osc build --keep-pkgs=RPMS.$cpu --vm-type=kvm --clean --noservice \
   "--build-opt=--vm-custom-opt=-cpu $cpu" standard
  (cd RPMS.$cpu && unrpm colord-color-profiles-1.4.6-0.x86_64.rpm)
done
md5sum RPMS*/usr/share/color/icc/colord/FOGRA28L_webcoated.icc
