From aac3a33d1e139743e86c66297a8d11d9fb35a7bd Mon Sep 17 00:00:00 2001 From: Simon South Date: Wed, 29 Dec 2021 12:46:07 -0500 Subject: gnu: ragel: Fix build of knot on aarch64-linux. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Apply a patch backported from Ragel's "ragel-6" branch that allows it to reliably generate usable code on aarch64-linux where the C/C++ "char" type is unsigned by default, fixing the build of Knot on this platform. * gnu/packages/patches/ragel-char-signedness.patch: New file. * gnu/local.mk (dist_patch_DATA): Add it. * gnu/packages/ragel.scm (ragel)[arguments]: Add custom phase for AArch64 that applies the patch. [native-inputs]: Add "patch" and patch file on AArch64.
