Source: libsynthesis Version: 3.4.0.47.4-2 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: locale X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that libsynthesis could not be built reproducibly. Some file lists are sorted differently depending on the locale. The attached patch fixes this by setting LC_ALL to C before sorting. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds

+Description: Make sorting independent of locale
+ Sort behaves differently depending on the configured locale.
+ To get reproducible results, sort the file lists
+ with the C locale.
