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

Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: kernel

The running kernel of the build machine is embedded in libcec.so.*:

  https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/libcec.html

  ./usr/lib/x86_64-linux-gnu/libcec.so.6.0.2

  compiled·on·Linux-5.16.0-0.bpo.4-amd64·...·,·features:·P8_USB,·DRM,·P8_detect,·randr,·Exynos,·Linux,·AOCEC
vs.
  compiled·on·Linux-5.10.0-13-amd64·...·,·features:·P8_USB,·DRM,·P8_detect,·randr,·Exynos,·Linux,·AOCEC


The attached patch updates the existing reproducible builds patch to use
CMAKE_SYSTEM_NAME instead of CMAKE_SYSTEM (which includes the running
kernel version).

With this patch applied, libcec should build reproducibly on
tests.reproducible-builds.org when it migrates to bookworm/testing!


To get it building reproducibly in unstable and experimental where
differing build paths are tested, it also needs to apply one of the
standard fixes mentioned here:

  https://tests.reproducible-builds.org/debian/issues/cmake_rpath_contains_build_path_issue.html


I intend to fix both issues shortly.


Thanks for maintaining libcec!


live well,

Subject: [PATCH 2/2] debian/patches: Update reproducible build patch to use
 Use CMAKE_SYSTEM_NAME instead of CMAKE_SYSTEM.

CMAKE_SYSTEM contains the running kernel version, which is likely to
be different between two builds.
