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

Date: Wed, 11 May 2022 17:55:31 -0700

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

Source: dvbtune
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/dvbtune and /usr/bin/xml2vdr:

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

  /build/1st/dvbtune-0.5.ds/dvbtune.c:140
  vs.
  /build/2/dvbtune-0.5.ds/2nd/dvbtune.c:140

The attached patches fix this by modifying the upstream Makefile to
append EXTRA_CFLAGS to CFLAGS, and passing EXTRA_CFLAGS in debian/rules
in the dh_auto_build phase. This passes the default CFLAGS from
dpkg-buildflags, which includes the -ffile-prefix-map argument to avoid
embedding the absolute path in compiled files.


With these patches applied, dvbtune should build reproducibly on
tests.reproducible-builds.org!


live well,
