A build number derived from the build time is embedded in various /usr/share/doc/freetds-doc/reference/*_source.html files: https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/freetds.html #define·TDS_VERSION_BUILD_NUMBER·856 vs. #define·TDS_VERSION_BUILD_NUMBER·1256 The attached patch to configure.ac fixes this by instead using the value of SOURCE_DATE_EPOCH for the BUILD_NUMBER if it is set, and falling back to the default behavior if it is not set. Alternately, I tried instead passing --date=@$SOURCE_DATE_EPOCH to the various date calls, but for some reason that was not sufficient. According to my local tests, with this patch applied freetds should build reproducibly on tests.reproducible-builds.org! Thanks for maintaining freetds! live well, vagrant
