From 0ac8f1f31c34a573689c1857cda5a1657029aee8 Mon Sep 17 00:00:00 2001 From: Andrew Robbins Date: Mon, 10 Dec 2018 20:37:18 -0500 Subject: Patch dejavu-fonts to require a recent fontforge fontforge was not able to create fonts in a reproducible manner until upstream revision 69e561773b91e37096a855f0353b1d6781a61250 Requiring at minimum a fontforge built from source on 2017-12-20 (the date the aforementioned revision was made) ensures that dejavu fonts are reproducible in Libreboot's build system. --- ...re-a-recent-fontforge-for-reproducibility.patch | 51 ++++++++++++++++++++++ 1 file changed, 51 insertions(+) create mode 100644 projects/dejavu-fonts/patches/0002-Require-a-recent-fontforge-for-reproducibility.patch (limited to 'projects') diff --git a/projects/dejavu-fonts/patches/0002-Require-a-recent-fontforge-for-reproducibility.patch b/projects/dejavu-fonts/patches/0002-Require-a-recent-fontforge-for-reproducibility.patch new file mode 100644 index 00000000..c9449e0c --- /dev/null +++ b/projects/dejavu-fonts/patches/0002-Require-a-recent-fontforge-for-reproducibility.patch @@ -0,0 +1,51 @@ +From 7098e955d8d0a061132aaec1429fc032e3d2edab Mon Sep 17 00:00:00 2001 +From: Andrew Robbins +Date: Mon, 10 Dec 2018 20:31:42 -0500 +Subject: [PATCH] Require a recent fontforge for reproducibility + +The required version is set to 20171220 which is the earliest +date from which fontforge built from source was able to produce +fonts deterministically.
