Subject: wiipdf: reproducible-builds: embedded build paths in /usr/bin/wiipdf

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

Source: wiipdf
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/wiipdf:

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

  /build/1st/wiipdf-1.4/wiipdf.c:114
  vs.
  /build/2/wiipdf-1.4/2nd/wiipdf.c:114

The attached patch fixes this by calling dh_auto_build instead of
$(MAKE) from debian/rules, which passes the default build flags
including -ffile-prefix-map, which avoids embedding the absolute path in
compiled files.

Alternately, updating to dh and a newer debhelper-compat level would
likely fix this as well, as it includes -ffile-prefix-map by default.


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