Source: airstrike Version: 0.99+1.0pre6a-7 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: fileordering X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that airstrike could not be built reproducibly. The list of source file is not sorted, which leads to a non-deterministic linking order. The attached patch fixes this. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
