Dear,

Using Guix 04a459a, the package ’git-annex’ is not reproducible:

  guix build git-annex
  guix build git-annex --no-grafts --check -K

return:

--8<---------------cut here---------------start------------->8---
guix build: error: derivation `/gnu/store/70qkv5hi5yq20m1h9jfm17m5lsc235mk-git-annex-8.20200908.drv' may not be deterministic: output `/gnu/store/cbrwrlwx6kg7l5q6ifl7q08icm17704g-git-annex-8.20200908' differs from ‘/gnu/store/cbrwrlwx6kg7l5q6ifl7q08icm17704g-git-annex-8.20200908-check’
--8<---------------cut here---------------end--------------->8---

then:

--8<---------------cut here---------------start------------->8---
$ diff -r --no-dereference /gnu/store/cbrwrlwx6kg7l5q6ifl7q08icm17704g-git-annex-8.20200908{,-check}
Binary files /gnu/store/cbrwrlwx6kg7l5q6ifl7q08icm17704g-git-annex-8.20200908/bin/git-annex and /gnu/store/cbrwrlwx6kg7l5q6ifl7q08icm17704g-git-annex-8.20200908-check/bin/git-annex differ
--8<---------------cut here---------------end--------------->8---

Is it expected?  I have not tried ’diffoscope’ yet to investigate.


Note that:

<https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/git-annex.html>

speaks about GCC patch… I do not know if it is relevant.


All the best,
simon

Thanks!  I shortened the comment a little and pushed to staging in
