Bug#1014564: tvtime: reproducible-builds: embedded build paths in /usr/bin/tvtime

[Vagrant Cascadian]

Source: tvtime
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/bin/tvtime:

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

  /build/1st/tvtime-1.0.11/src/speedy.c:1933
  vs.
  /build/2/tvtime-1.0.11/2nd/src/speedy.c:1933

The attached patch fixes this by switching to using debhelper compat 13
and debhelper's "dh" command, which passes compiler flags to avoid
embedding the build path (e.g. -ffile-prefix-map), and avoids embedding
differing buildids via rpath (even though rpath is later stripped).


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


live well,
