From 122a20d062e83fa494f8327081746b725dc60d80 Mon Sep 17 00:00:00 2001 From: James Clark Date: Mon, 16 Aug 2021 14:07:05 +0100 Subject: [PATCH] tools build: Fix feature detect clean for out of source builds [ Upstream commit 8af52e69772d053bc7caab12ad1c59f18ef2e3e2 ] Currently the clean target when using O= isn't cleaning the feature detect output. This is because O= and OUTPUT= are set to canonical paths. For example in tools/perf/Makefile: FULL_O := $(shell cd $(PWD); readlink -f $(O) || echo $(O)) This means that OUTPUT ends in a / and most usages prepend it to a file without adding an extra /. This line that was changed adds an extra / before the 'feature' folder but not to the end, resulting in a clean command like this: rm -f /tmp/build//featuretest-all.bin ... After the change the clean command looks like this: rm -f /tmp/build/feature/test-all.bin ...
