Subject: netcdf-parallel: please make the libnetcdf.settings file reproducible

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

Source: netcdf-parallel
Version: 1:4.7.4-1
Severity: wishlist
Tags: patch
User: reproducible-builds@lists.alioth.debian.org

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
netcdf-parallel generates a non-deterministic libnetcdf.settings file.

There is already a reproducible-settings patch which ensures that
CFLAGS do not leak into this file, but this misses the (possibly new)
absolute build path.

Patch attached, although it would of course be cleaner to merge it
into the existing reproducible-settings.patch file; I just didn't want
you to send you a mindmending patch of a patch.

Regards,

I confirmed this patch is still needed to fix the issue. Any chance we
could fix this in time for bookworm? Would an NMU be helpful?

live well,
