Subject: modglue: reproducible-builds: Embedded build path in example Makefile

Date: Mon, 23 May 2022 15:57:37 -0700

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

Source: modglue
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build path is embedded in /usr/share/doc/libmodglue1-dev/examples/Makefile:

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

  g++·-g·-O2·-ffile-prefix-map=/build/1st/modglue-1.17=.·-fstack-protector-strong ...
  vs.
  g++·-g·-O2·-ffile-prefix-map=/build/2/modglue-1.17/2nd=.·-fstack-protector-strong ...

The attached patch fixes this by replacing the build path with a
placeholder string in debian/rules.

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

Thanks for maintaining modglue!

live well,
