Source: pyephem Version: 3.7.6.0-6 Severity: wishlist Tags: patch upstream User: reproducible-bui...@lists.alioth.debian.org Usertags: fileordering X-Debbugs-Cc: reproducible-bui...@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that pyephem could not be built reproducibly. During build it links object files in non-deterministic order. The attached patch fixes this by sorting the list of source files. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
