From 45901057b4103eeb745e080521678c0e43e0eca1 Mon Sep 17 00:00:00 2001 From: Andre Noll Date: Mon, 26 Apr 2021 00:57:12 +0200 Subject: [PATCH] build: Error out on implicit function declarations. Replacing lopsub.h by an empty file builds a buggy lopsubgen-stage1 executable which segfaults due to a format string mismatch caused by the implicit declaration of lls_version(). In this package all functions are supposed to be declared, so let's fail the build if any undeclared functions are found.
