From aa1e74745c93534a14981616b92956e920a01dc5 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 18 Mar 2020 16:58:11 +0100 Subject: [PATCH] Makefile: don't hang the build if there are no file lists In very limited configurations, it is possible to have a case where no .files-list-staging.txt files are created. In this case: cat $(sort $(wildcard $(BUILD_DIR)/*/.files-list-staging.txt)) > \ $(BUILD_DIR)/packages-file-list-staging.txt becomes: cat > \ $(BUILD_DIR)/packages-file-list-staging.txt which of course makes the build hang.. forever. So we fix this by checking the list is not empty. To keep the code readable, we introduce an intermediate variable to store the list of these files.
