Bug#1024283: ipsvd: reproducible-builds: buildid differences in various binaries

[Vagrant Cascadian]

Source: ipsvd
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 buildid differs when built from a different path for various
binaries in /usr/bin:

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

The attached patch to debian/rules fixes this by adding
-ffile-prefix-map to CFLAGS.

Switching to dh and a recent debhelper compat level might also solve
this problem.

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

Thanks for maintaining ipsvd!

live well,
  vagrant
