Subject: dustmite: reproducible-builds: build path embedded in /usr/bin/dustmite

Date: Tue, 27 Sep 2022 14:12:03 -0700

[Message part 1 (text/plain, inline)]

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

The build path is embedded in /usr/bin/dustmite:

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

  /build/1st/dustmite-0.0.430/dustmite.d:1
  vs.
  /build/2/dustmite-0.0.430/2nd/dustmite.d:1

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

This is not the only issue affecting the reproducibility of dustmite,
but another patch regarding timestamps will be submitted shortly.

Thanks for maintaining dustmite!

live well,
