Subject: transcalc: reproducible-builds: embedded build paths in /usr/bin/transcalc

Date: Mon, 23 May 2022 09:37:28 -0700

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

Source: transcalc
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/transcalc:

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

  /build/1st/transcalc-0.14/src/transcalc.c:214
  vs.
  /build/2/transcalc-0.14/2nd/src/transcalc.c:214

The attached patch fixes this by explicitly passing CFLAGS to
dh_auto_build in debian/rules, which includes the -ffile-prefix-map
argument to avoid embedding the absolute path in compiled files.


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


live well,
