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

Source: gwaei
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/bin/gwaei:

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

  /build/1st/gwaei-3.6.2/src/gwaei/gwaei.c:47
  vs.
  /build/2/gwaei-3.6.2/2nd/src/gwaei/gwaei.c:47

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

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

Thanks for maintaining gwaei!

live well,
  vagrant
