Hi! While working on the “reproducible builds” effort [1], we have noticed that zipios++ could not be built reproducibly since it suffers from timestamps in manpages generated by doxygen [2]. The reproducible builds team is building packages using a version of doxygen which has been patched to honour the environment variable $SOURCE_DATE_EPOCH [3]. This results in doxygen using the last date in debian/changelog as the timestamp for its man page output which causes packages to become reproducible [4]. During our tests $SOURCE_DATE_EPOCH is exported by the debhelper from our experimental git repository which we have patched such that packages using dh (debhelper >= 9) in debian/rules become automatically reproducible. This unfortunately does not make the package zipios++ reproducible because it does not use dh in debian/rules but instead classic debhelper. There are two solutions for zipios++ : 1. To rewrite debian/rules to use dh 2. To implement the attached patch which exports $SOURCE_DATE_EPOCH in debian/rules.
