[Reproducible-builds] Bug#819767: libtool: please make the build reproducible (timestamps, fileordering, hostname, umask)

[rain1 at openmailbox.org]

Source: libtool
Version: 2.4.6
Severity: wishlist
Tags: patch
User: reproducible-builds at lists.alioth.debian.org

Hi!

While working on the “reproducible builds” effort [1], we have noticed
that libtool could not be built reproducibly.

The attached patch removes extra timestamps from the build system and
ensure a stable file order when creating the source archive as well as 
replacing uses of the `hostname` command with the fixed string 
"localhost". Once applied, libtool can be built reproducibly in our 
current experimental framework.

I also added to rules: dh_strip_nondeterminism -i/-a to the makefile 
before the compress stage.
