Bug#1020650: tmpreaper: reproducible-builds: Embedded build path in /usr/sbin/tmpreaper

[Vagrant Cascadian]

Source: tmpreaper
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The build path is embedded in /usr/sbin/tmpreaper:

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

  /build/1st/tmpreaper-1.6.17/tmpreaper.c:752
  vs.
  /build/2/tmpreaper-1.6.17/2nd/tmpreaper.c:752

The attached patch fixes this by passing the -ffile-prefix-map argument
via CFLAGS in debian/rules. Another option that *might* fix this and
other issues would be to fully switch to dh and a recent debhelper
compat level.


With this patch applied tmpreaper should build reproducibly on
tests.reproducible-builds.org!


Thanks for maintaining tmpreaper!


live well,
