The documented way to build kselftest is to run
make -C tools/testing/selftests
with an optional "O=..." parameter to specify the output directory.
However, all of the above assume you run make from the source directory. while other make commands can simply be run from the output directory, too (the autogenerated Makefile in the output directory takes care of this).
Add a "kselftest-build" target, so "make kselftest-build" can be used from either the source or output directory.
Signed-off-by: Geert Uytterhoeven geert+renesas@glider.be --- Perhaps this make target should just be called "kselftest", and the existing "kselftest" target be renamed to "kselftest-run"? --- Documentation/dev-tools/kselftest.rst | 4 ++++ Makefile | 5 +++++ 2 files changed, 9 insertions(+)
