Bug#1010870: pidgin-blinklight: reproducible-builds: embedded build paths in various binaries

[Vagrant Cascadian]

Source: pidgin-blinklight
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/lib/purple-2/pidgin-blinklight.so and
/usr/lib/pidgin-blinklight/blinklight-fixperm:

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

  /build/1st/pidgin-blinklight-0.11.1/src/blinklight-fixperm.c:17
  vs.
  /build/2/pidgin-blinklight-0.11.1/2nd/src/blinklight-fixperm.c:17


The attached patch fixes this by updating to use debhelper compat level
13 and switching to use "dh" in debian/rules. This passes the default
CFLAGS from dpkg-buildflags, which includes the -ffile-prefix-map
argument to avoid embedding the absolute path in compiled files.


As a bonus, it should also fix https://bugs.debian.org/999100


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


live well,
