Bug#1021454: dbview: reproducible-builds: build path embedded in /usr/bin/dbview

[Vagrant Cascadian]

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

The build path is embedded in /usr/bin/dbview:

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

  /build/1st/dbview-1.0.4/dbview.c:62
  vs.
  /build/2/dbview-1.0.4/2nd/dbview.c:62

The attached patch to the upstream Makefile fixes this by adding
-ffile-prefix-map to CFLAGS.

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

Thanks for maintaining dbview!

live well,
  vagrant
