Subject: [PATCH RESEND v3 2/2] selftests: fix prepending $(OUTPUT) to $(TEST_PROGS)
Date: Thu, 24 Oct 2019 14:13:47 +0200	[thread overview]
Message-ID: <20191024121347.22189-3-iii@linux.ibm.com> (raw)
In-Reply-To: <20191024121347.22189-1-iii@linux.ibm.com>

Currently the following command fails:

    linux# make kselftest TARGETS=bpf O=/mnt/linux-build
    # selftests: bpf: test_libbpf.sh
    # ./test_libbpf.sh: line 23: ./test_libbpf_open: No such file or directory
    # test_libbpf: failed at file test_l4lb.o
    # selftests: test_libbpf [FAILED]

The current logic prepends $(OUTPUT) only to the first member of
$(TEST_PROGS). After that, run_one() does

   cd `dirname $TEST`

For all tests except the first one, `dirname $TEST` is ., which means
they cannot access the files generated in $(OUTPUT).

Fix by using $(addprefix) to prepend $(OUTPUT) to each member of
$(TEST_PROGS).

Fixes: 1a940687e424 ("selftests: lib.mk: copy test scripts and test files for make O=dir run")
