Source: yocto-reader Version: 0.9.4 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi, While working on the "reproducible builds" effort [1], we have noticed that yocto-reader could not be built reproducibly. The attached patch removes timestamps from the build system. Once applied, yocto-reader can be built reproducibly in our current experimental framework.
