Source: lapack Version: 3.6.0-2 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: locale randomness X-Debbugs-Cc: reproducible-builds@lists.alioth.debian.org
Hi! While working on the "reproducible builds" effort [1], we have noticed that lapack could not be built reproducibly. It includes a log file of test results (testing_results.txt), which includes measured run times of the tests. The static library libblas.a can also contain objects in a different order, depending on the configured locale. The attached patch removes the test log, as it provides no value to the user, and sorts the files packed into the static library locale-independently. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
