When running "make kselftests": make[3]: Entering directory 'tools/gpio' Makefile:24: tools/build/Makefile.include: No such file or directory make[3]: *** No rule to make target 'tools/build/Makefile.include'. Stop. When building kselftest in a separate output directory, the gpio tools are still built in the source directory. Fix this by passing the correct source and build paths to the make subprocess. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- Marked RFC as there are still issues with this approach: - "make kselftest O=" needs: all: $(TEST_PROGS_EXTENDED) "make kselftest" needs that line to be replaced by: TEST_GEN_PROGS_EXTENDED := $(TEST_PROGS_EXTENDED) Having both lines doesn't help. - gpio-mockup-chardev is no longer built. --- tools/testing/selftests/gpio/Makefile | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/tools/testing/selftests/gpio/Makefile b/tools/testing/selftests/gpio/Makefile index 0bb80619db580af1..1eb4304fcfcbad67 100644 --- a/tools/testing/selftests/gpio/Makefile +++ b/tools/testing/selftests/gpio/Makefile @@ -13,20 +13,22 @@ TEST_PROGS := gpio-mockup.sh TEST_FILES := gpio-mockup-sysfs.sh TEST_PROGS_EXTENDED := gpio-mockup-chardev -GPIODIR := $(realpath ../../../gpio) +GPIOSRCDIR := $(abspath $(CURDIR)/../../../gpio) +GPIOOBJDIR := $(abspath $(OUTPUT)/../../../gpio) GPIOOBJ := gpio-utils.o all: $(TEST_PROGS_EXTENDED) override define CLEAN $(RM) $(TEST_PROGS_EXTENDED) - $(MAKE) -C $(GPIODIR) OUTPUT=$(GPIODIR)/ clean + $(MAKE) -C $(GPIOSRCDIR) OUTPUT=$(GPIOOBJDIR)/ clean endef KSFT_KHDR_INSTALL := 1 include ../lib.mk -$(TEST_PROGS_EXTENDED): $(GPIODIR)/$(GPIOOBJ) +$(TEST_PROGS_EXTENDED): $(GPIOOBJDIR)/$(GPIOOBJ) -$(GPIODIR)/$(GPIOOBJ): - $(MAKE) OUTPUT=$(GPIODIR)/ -C $(GPIODIR) +$(GPIOOBJDIR)/$(GPIOOBJ): + mkdir -p $(GPIOOBJDIR) + $(MAKE) OUTPUT=$(GPIOOBJDIR)/ -C $(GPIOSRCDIR) -- 2.17.1
