Subject: freecdb: reproducible-builds: embedded build paths in various binaries

Date: Mon, 23 May 2022 15:33:52 -0700

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

Source: freecdb
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 various binaries in /usr/bin:

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

  /usr/bin/cdbdump

  /build/1st/freecdb-0.76/cdbdump.c:45
  vs.
  /build/2/freecdb-0.76/2nd/cdbdump.c:45

The attached patch fixes this by explicitly passing CFLAGS to a
dh_auto_build override in debian/rules, which includes the
-ffile-prefix-map argument used to avoid embedding build paths.


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