Source: cppreference-doc Version: 20140827+dfsg0-1 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: fileordering
Hi, the package can currently not be build reproducibly, because files are not read in a deterministic order. The attached patch fixes this by sorting files/items before they are used to produce output that will land in the package. Regards, Reiner
