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

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

The buildid differs in /usr/games/xjump when built with a different
build path:

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

The attached patch fixes this in debian/rules by passing
-ffile-prefix-map in CFLAGS.

Alternately, adapting this packge to use the default flags passed via
dpkg-buildflags should solve this issue as well.

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

Thanks for maintaining xjump!

live well,
  vagrant
