From 64ae7db88a9b22470d31d032a87fddd5fb4a2ab7 Mon Sep 17 00:00:00 2001 From: Chris Lamb Date: Sat, 15 Feb 2020 09:32:59 +0000 Subject: Make the build reproducible Whilst working on the Reproducible Builds effort [0] we noticed that mate-desktop could not be built reproducibly. This is is because it generated a "release year" etc. based on the current build date which was embedded in the binary and possibly other files. A patch attached that uses SOURCE_DATE_EPOCH [1] instead. As a side-effect, this fixes the (accidental) reset of MATE_DATE in the Autotools build system in inherited from mate-desktop-environment.git. This was originally filed in Debian as #951357 [2].
