Bug#1011429: dds2tar: reproducible-builds: embedded build paths in /usr/bin/dds-dd

[Vagrant Cascadian]

Source: dds2tar
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/dds-dd:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/dds2tar.html

  /build/1st/dds2tar-2.5.2/dds2tar.c:382
  vs.
  /build/2/dds2tar-2.5.2/2nd/dds2tar.c:382

The attached patch fixes this by adjusting the Makefile to add CFLAGS to
the CCFLAGS variable, which includes the -ffile-prefix-map argument to
avoid embedding the absolute path in compiled files.


With this patch applied, dds2tar should build reproducibly on
tests.reproducible-builds.org!


live well,
