Subject: metapixel: reproducible-builds: Embedded build path in /usr/bin/metapixel

Date: Mon, 02 May 2022 08:23:31 -0700

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

Source: metapixel
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/metapixel and
/usr/bin/metapixel-imagesize:

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

  /build/1st/metapixel-1.0.2/rwimg/readimage.c:115
  vs.
  /build/2/metapixel-1.0.2/2nd/rwimg/readimage.c:115


The attached patch to debian/rules fixes this by passing the
-ffile-prefix-map compiler flag via dh_auto_build.


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


Thanks for maintaining metapixel!


live well,

This avoids embedding the absolute build path in /usr/bin/metapixel*
