[Pkg-electronics-devel] Bug#977415: klayout: reproducible builds: Binaries contain build timestamps

[Vagrant Cascadian]

Source: klayout
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

Several binaries shipped with klayout include the build time:

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

  ./usr/lib/klayout/klayout
  124 	2021-12-18
  124 	2020-11-16


The attached patch fixes this by adjusting the call to date in
version.sh to use the SOURCE_DATE_EPOCH environment variable.

This patch does not resolve all reproducibility issues (e.g. build
paths), but combined with a patch soon to follow, should make klayout
reproducible when it lands in bullseye (where build paths are not
tested).


Thanks for maintaining klayout!


live well,
