Source: dctrl-tools Version: 2.24-2 Severity: wishlist Tags: patch User: [email protected] Usertags: fileordering X-Debbugs-Cc: [email protected]
Hi! While working on the "reproducible builds" effort [1], we have noticed that dctrl-tools could not be built reproducibly. It collects source files without sorting, which causes the object files to be linked in a non-deterministic order. The attached patch fixes this by sorting the object files. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
