Hi, GNU Make now has a --shuffle option that simulates non-deterministic ordering of target prerequisites. See https://trofi.github.io/posts/238-new-make-shuffle-mode.html and also previous work in Debian by Santiago Vila: https://people.debian.org/~sanvila/make-shuffle/ This package fails to build with make --shuffle=random. This is likely to be caused by a missing dependency in debian/rules or an upstream Makefile. More information about this mass bug filing is available at https://wiki.debian.org/qa.debian.org/FTBFS/Shuffle Relevant part (hopefully): The full build log is available from: http://qa-logs.debian.net/2025/05/05/shuffle/random/cssc_1.4.1-1_unstable_random.log If you reassign this bug to another package, please mark it as 'affects'-ing this package.
