Bug#1029800: aribas: reproducible-builds: build id differences in /usr/bin/aribas

[Vagrant Cascadian]

Source: aribas
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath

Building from a different directory results in a different build id
embedded in /usr/bin/aribas:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/aribas.html

  Build·ID:·7652115b45271e393b31873efede354e1cb36769
  vs.
  Build·ID:·49cfcb42aa13407e5d7e5ce6e50352610d448a78

The attached patch to the upstream src/Makefile fixes this by adding the
-ffile-prefix-map argument in CFLAGS, removing the build path before the
buildid is calculated.

According to my local tests, with this patch applied aribas should build
reproducibly on tests.reproducible-builds.org!

Thanks for maintaining aribas!

live well,
