From deb4f0a595e75a2d708ebe9ce26fb4d5fcfa0968 Mon Sep 17 00:00:00 2001 From: Maxime Devos Date: Wed, 14 Jul 2021 13:12:54 +0200 Subject: libgpg-error: Prevent silent miscompilation some systems. * gnu/packages/gpg.scm (libgpgerror)[arguments]<#:phases>{cross-symlinks}: Only link to src/syscfg/lock-obj-pub.linux-gnu.h if the package is being compiled for a Linux target. Do not link either if the architecture is unknown, as the headers vary with the architecture.
