Subject: akonadi-contacts: reproducible-builds: BuildId differences triggered by RPATH

Date: Tue, 18 Jan 2022 17:12:54 -0800

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

Source: akonadi-contacts
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/akonadi-contacts.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, akonadi-contacts should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining akonadi-contacts!

live well,
  vagrant

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.
