[PATCH/RFC 12/12] selftests: gpio: Fix building tools/gpio from kselftests

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

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.
