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

Source: ipfm
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 /usr/sbin/ipfm:

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

  /build/1st/ipfm-0.11.5/source/ipfm.c:62
  vs.
  /build/2/ipfm-0.11.5/2nd/source/ipfm.c:62

The attached patch fixes this in debian/rules by passing CFLAGS to make
with the -ffile-prefix-map argument.

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

Thanks for maintaining ipfm!

live well,
  vagrant
