Bug#1010828: bbrun: reproducible-builds: embedded build paths in /usr/bin/bbrun

[Vagrant Cascadian]

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

The build path is embedded in /usr/bin/bbrun:

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

  /build/1st/bbrun-1.6/bbrun/bbrun.c:59
  vs.
  /build/2/bbrun-1.6/2nd/bbrun/bbrun.c:59

The attached patches fix this by patching the Makefile to accept an
EXTRA_CFLAGS variable, and then adjusting debian/rules to pass the
default CFLAGS via the EXTRA_CFLAGS variable.

The default CFLAGS include the -ffile-prefix-map argument which is used
to avoid embedding the absolute path in compiled files.


With these patches applied, bbrun should build reproducibly on
tests.reproducible-builds.org!


live well,
