Subject: soundkonverter: reproducible-builds: BuildId differences triggered by RPATH

Date: Mon, 17 Jan 2022 22:44:24 -0800

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

Source: soundkonverter
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The RPATH contains the build path resulting in different buildid:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/soundkonverter.html

The attached patch to debian/rules passes
-DCMAKE_BUILD_RPATH_USE_ORIGIN=ON via a dh_auto_configure override,
which should use a relative path for RPATH.

Alternately, updating the packaging to debhelper compat level 14 should
fix this, although it is currently an experimental compat level.

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

Thanks for maintaining soundkonverter!

live well,

Subject: [PATCH] debian/rules: Pass -DCMAKE_BUILD_RPATH_USE_ORIGIN=ON via
 dh_auto_configure override.

This avoids embedding the full path in RPATH, which triggers BuildId
differences.
