From 25c9e6e8df956fe342e6f1969c96921c4f15b4e4 Mon Sep 17 00:00:00 2001 From: Sebastiaan van Stijn Date: Fri, 15 Mar 2024 17:42:58 +0100 Subject: [PATCH] Makefile: generate-files: fix check for empty TMP_OUT commit c655b7dc78b3a0773f33f92e9c923a2e48e9c62b added a check to make sure the TMP_OUT variable was not set to an empty value, as such a situation would perform an `rm -rf /**` during cleanup. However, it was a bit too eager, because Makefile conditionals (`ifeq`) are evaluated when parsing the Makefile, which happens _before_ the make target is executed. As a result `$@_TMP_OUT` was always empty when the `ifeq` was evaluated, making it not possible to execute the `generate-files` target. This patch changes the check to use a shell command to evaluate if the var is set to an empty value.
