Subject: lomiri-action-api: reproducible-builds: build paths trigger differences

Date: Sun, 09 Apr 2023 17:38:48 -0700

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

Source: lomiri-action-api
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, as
well as some build paths embedded in documentation:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/lomiri-action-api.html

  /usr/share/doc/lomiri-action-doc/qml/lomiri-action-qml-api.index.gz

  ... filepath="/build/1st/lomiri-action-api-1.1.2/documentation/qml/qml-api/Action.qml
  vs.
  ... filepath="/build/2/lomiri-action-api-1.1.2/2nd/documentation/qml/qml-api/Action.qml

The attached patches to debian/rules fix this by passing
-DCMAKE_BUILD_RPATH_USE_ORIGIN=ON via a dh_auto_configure override and
adds a dh_installdocs override to strip the build path from the
documentation.


With these patches applied, based on my local tests, lomiri-action-api
should build reproducibly on tests.reproducible-builds.org!


Thanks for maintaining lomiri-action-api!

live well,
  vagrant

Subject: [PATCH 1/2] 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.
