Source: asymptote Version: 2.37.real-1 Severity: wishlist Tags: patch upstream User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Dear Maintainer, While working on the `reproducible builds' effort [1], we have noticed that 'asymptote' could not be built reproducibly. The attached patch honours the SOURCE_DATE_EPOCH environment variable [2] to get a reproducible documentation date from the last debian changelog entry. Once applied, asymptote can be built reproducibly in our current experimental framework. Regards, Alexis Bienvenüe.
