Source: gravitation Version: 3+dfsg1-4 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps
Hi! While working on Debian's “reproducible builds” effort [1], we have noticed that gravitation doesn't build reproducibly. PNG icons generated with convert have timestamps embedded. The attached patch fixes this by preventing the embedding of timestamps. Once applied, gravitation can be built reproducibly in our current experimental framework. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
