Hi,
While working on the "reproducible builds" effort [1], we have noticed
that libdevice-cdio-perl could not be built reproducibly, but more
crucially that the files generated by SWIG are non-deterministically
re-generated (or not).
This is problematic as Debian packages should. of course, be generated
from the provided sources, at least so that modifying the source will
result in a modified binary.
The files in question are lib/perl*.pm. This was detected because SWIG
was adding a "generated by version X", where X appears to flap between
the generated versions of the file shipped with libdevice-cdio-perl (as
it happens, version 1.3.40) and the current version of SWIG in unstable
(at the time of writing, 2.0.12)
Here's one way of solving the problem:
override_dh_auto_clean:
rm -f lib/perl*.pm
dh_auto_clean
.. but I wonder if this is a deeper problem with Module::Build and thus
affecting the entire archive. For this reason, I have avoided the
"patch"
tag. Hopefully, someone with more knowledge will be able to tell the
impact.
