Bug#1037309: libint: reproducible-builds: build date in PDF file

[Vagrant Cascadian]

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

The date is embedded in a shipped PDF file:

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

  /usr/share/doc/libint-dev/progman.pdf.gz

The attached patch sets FORCE_SOURCE_DATE in debian/rules to ensure that
texlive respects SOURCE_DATE_EPOCH for a reproducible date.

According to my local tests, with this patch applied libint should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining libint!

live well,
  vagrant
