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

Date: Fri, 17 Dec 2021 16:04:30 -0800

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

Source: meshlab
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/meshlab.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.

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

Thanks for maintaining meshlab!

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.

Oh wow, thanks! I was trying to figure out why it wasn't reproducible even
though it "should have" been. I'll apply this soon.
