Bug#1020759: postal: reproducible-builds: Embedded build paths in binaries

[Vagrant Cascadian]

Source: postal
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 various binaries:

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

  /usr/bin/postal-list

  /build/1st/postal-0.76+nmu1/expand.cpp:14·(discriminator·2)
  vs.
  /build/2/postal-0.76+nmu1/2nd/expand.cpp:14·(discriminator·2)

The attached patch to debian/rules fixes this by passing the default
CFLAGS to make.

Alternately, updating to use dh and a recent debhelper compat version
might also fix this.

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

Thanks for maintaining postal!

live well,
  vagrant
