<p>Reproducible builds are a set of software development
practices which create a verifiable path from human readable
source code to the binary code used by computers. In brief,
the idea is that building the same binary, software package,
document, or other binary artifact twice from the same source
produces identical output. The <a
href="https://reproducible-builds.org/">reproducible-builds.org website</a>
provides background information and documentation on making
builds reproducible.</p>
<p>Many folks have contributed to the reproducible build effort
in &os; src and ports over the last decade. There are many
practical benefits of reproducible builds, such as bandwidth
and storage savings. However, there is a growing interest in
the broad open source and free software communities,
primarily from a software and toolchain integrity perspective.
Over the last few years, some members of the Debian Project
have led a comprehensive and structured reproducible builds
effort.</p>
<p>Baptiste Daroussin and Ed Maste attended the first
Reproducible Builds Summit in Athens last year. Since then,
Ed investigated the state of build reproducibility
in the ports tree, and presented
<i>Reproducible Builds in &os;</i> at BSDCan 2016. With
some work in progress patches, over 80% of the &os; ports tree
builds reproducibly.</p>
<p>The Diffoscope tool performs in-depth comparison of files,
archives, or directories to understand why a binary artifact
does not build reproducibly. Diffoscope results for the
nonreproducible builds in Ed's talk are available at one of
the links above.</p>
