Bug#990332: libcddb: reproducible-builds: Example Makefile embeds build paths and binary paths

[Vagrant Cascadian]

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

The build path, several binary paths, and the value of the SHELL
variable are embedded in example Makefiles shipped in the package:

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

  ./usr/share/doc/libcddb2-dev/examples/Makefile.gz

  ACLOCAL·=·${SHELL}·'/build/1st/libcddb-1.3.2/missing'·aclocal-1.16
  vs.
  ACLOCAL·=·${SHELL}·'/build/2/libcddb-1.3.2/2nd/missing'·aclocal-1.16

  GREP·=·/bin/grep
  vs.
  GREP·=·/usr/bin/grep

  SHELL·=·/bin/bash
  vs.
  SHELL·=·/bin/sh

Since these values may differ with the installed system, in order to use
the example Makefiles, a person would have to regenerate them from
Makefile.am or Makefile.in, which are also provided.

The attached patch adjusts debian/libcddb2-dev.examples to only install
Makefile.in and Makefile.am.


If that is somehow not an option, an alternate option would be to
sanitize the Makefiles stripping the build path (or replacing with
/usr/src?), and possibly passing various variables to configure
(e.g. GREP=/bin/grep, SHELL=/bin/sh, ...).


Thanks for maintaining libcddb!


live well,
