Source: gdbm Version: 1.8.3-13.1 Severity: wishlist Tags: patch User: reproducible-builds@lists.alioth.debian.org Usertags: timestamps
Hi! While working on the “reproducible builds” effort [1], we have noticed that gdbm could not be built reproducibly. The attached patch fixes several issues: it removes the build date and time from the version string, calls strip-nondeterminism on static libraries, and adjust file mtimes before building the binary packages. Once applied, gdbm can be built reproducibly with the current experimental framework.
