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

Date: Mon, 23 May 2022 15:09:19 -0700

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

Source: gdigi
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/gdigi:

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

  /build/1st/gdigi-0.4.0+git20200615+1c2c89f/gdigi.c:43
  vs.
  /build/2/gdigi-0.4.0+git20200615+1c2c89f/2nd/gdigi.c:43

The attached patch fixes this by passing CFLAGS via EXTRA_CFLAGS in a
dh_auto_build override in debian/rules. This allows passing the default
build flags including -ffile-prefix-map, which avoids embedding the
absolute path in compiled files.


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