Subject: imagination: reproducible-builds: embedded build paths in various binaries

Date: Mon, 23 May 2022 17:20:53 -0700

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

Source: imagination
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 various binaries:

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

  /usr/bin/imagination

  /build/1st/imagination-3.6/src/imgcellrendereranim.c:63
  vs.
  /build/2/imagination-3.6/2nd/src/imgcellrendereranim.c:63

The attached patch fixes this by explicitly passing CFLAGS to a
dh_auto_build override in debian/rules, which includes the
-ffile-prefix-map argument used to avoid embedding build paths.


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


live well,
