Package: ns3 Version: 3.22+dfsg-1 Severity: wishlist Template taken from https://wiki.debian.org/ReproducibleBuilds/Contribute Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps
Hi! While working on the "reproducible builds" effort [1], we have noticed that ns3 could not be built reproducibly. The attached patch removes extra timestamps from the build system. Once applied, ns3 can be built reproducibly in our current experimental framework. [1]: https://wiki.debian.org/ReproducibleBuilds
