Bug#1020725: snapper: reproducible-builds: Embedded build path in example Makefile

[Vagrant Cascadian]

Source: snapper
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/share/doc/libsnapper-dev/examples/Makefile:

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

  ACLOCAL·=·${SHELL}·'/build/1st/snapper-0.10.2/missing'·aclocal-1.16
  vs.
  ACLOCAL·=·${SHELL}·'/build/2/snapper-0.10.2/2nd/missing'·aclocal-1.16

The attached patch fixes this in debian/rules by removing the Makefile
in a dh_installexamples override. Removing the Makefile seems better
than sanitizing the build path, as in order to use it, one would have to
regenerate it from the provided Makefile.in or Makefile.am to match the
running system.

With this patch applied (and another recently submitted to fix usrmerge
issues) snapper should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining snapper!

live well,
  vagrant
