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

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

Source: cldump
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/cldump:

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

  /build/1st/cldump-0.11~dfsg/src/cldump.c:180
  vs.
  /build/2/cldump-0.11~dfsg/2nd/src/cldump.c:180

The attached patch fixes this by explicitly passing CFLAGS to
dh_auto_build in debian/rules, which includes flags to avoid embedding
the build path.


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

Subject: [PATCH] debian/rules: Pass CFLAGS via dh_auto_build override.

src/Makefile sets CFLAGS explicitly, ignoring CFLAGS from the
environment. This means various default flags are otherwise ignored,
e.g. -ffile-prefix-map which is used to avoid embedding build paths
for reproducible builds.
