A date string that defaults to the current date is embedded in /usr/share/metainfo/com.obsproject.Studio.appdata.xml, causing builds on different days to not build reproducibly. https://tests.reproducible-builds.org/debian/rb-pkg/bullseye/amd64/diffoscope-results/obs-studio.html 21 ····<release·version="26.0.2+dfsg1-1"·date="2021-12-18"/> 21 ····<release·version="26.0.2+dfsg1-1"·date="2020-11-15"/> This can be fixed by setting a value from the configure target that uses SOURCE_DATE_EPOCH: https://reproducible-builds.org/docs/source-date-epoch/ The attached patch does this. Alternately, it may be worth exploring patching UI/xdg-data/CMakeLists.txt to support SOURCE_DATE_EPOCH and get the support merged upstream. Thanks for maintaining obs-studio! live well, vagrant
