[Pkg-electronics-devel] Bug#918533: gnucap-python: please make the build reproducible

[Chris Lamb]

Source: gnucap-python
Version: 0.0.2-1
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that gnucap-python could not be built reproducibly.

This is because it uses:

  $ echo "\n"

… or similar which is not the same across dash/bash etc, resulting in
a diff of:

│ │ │ │ ├── NEWS
│ │ │ │ │ @@ -1,3 +1 @@
│ │ │ │ │ -0.0.0
│ │ │ │ │ -=====
│ │ │ │ │ -* initial release
│ │ │ │ │ +0.0.0\n=====\n* initial release

A patch is attached, although given that this NEWS entry is pretty
meaningless, it is unclear whether the best course of action would
be to simply remove its creation…
