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

Date: Sat, 15 Jan 2022 16:08:15 -0800

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

Source: imath
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/imath.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.


There are still other outstanding reproducibility issues even with this
patch applied, but applying this patch should reduce the diff
significantly, allowing diffoscope runs on tests.reproducible-builds.org
to complete before timing out.


Thanks for maintaining imath!


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.
