Source: bitcoin Version: 0.10.2-3 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 bitcoin could not be built reproducibly. A file list is sorted differently depending on the locale. The attached patch fixes this by setting to LC_ALL to C before sorting. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
