From mboxrd@z Thu Jan 1 00:00:00 1970 From: Michael Ellerman Subject: [PATCH 1/5] selftests: Fix selftests build to just build, not run tests Date: Thu, 9 Feb 2017 19:56:26 +1100 Message-ID: <1486630590-9410-1-git-send-email-mpe@ellerman.id.au> Return-path: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: linuxppc-dev-bounces+glppe-linuxppc-embedded-2=m.gmane.org@lists.ozlabs.org Sender: "Linuxppc-dev" To: shuahkh@osg.samsung.com, bamvor.zhangjian@huawei.com Cc: linuxppc-dev@ozlabs.org, linux-kernel@vger.kernel.org, linux-kselftest@vger.kernel.org, linux-api@vger.kernel.org List-Id: linux-api@vger.kernel.org In commit 88baa78d1f31 ("selftests: remove duplicated all and clean target"), the "all" target was removed from individual Makefiles and added to lib.mk. However the "all" target was added to lib.mk *after* the existing "runtests" target. This means "runtests" becomes the first (default) target for most of our Makefiles. This has the effect of causing a plain "make" to build *and run* the tests. Which is at best rude, but depending on which tests are run could oops someone's build machine. $ make -C tools/testing/selftests/ ... make[1]: Entering directory 'tools/testing/selftests/bpf' gcc -Wall -O2 -I../../../../usr/include test_verifier.c -o tools/testing/selftests/bpf/test_verifier gcc -Wall -O2 -I../../../../usr/include test_maps.c -o tools/testing/selftests/bpf/test_maps gcc -Wall -O2 -I../../../../usr/include test_lru_map.c -o tools/testing/selftests/bpf/test_lru_map #0 add+sub+mul FAIL Failed to load prog 'Function not implemented'! #1 unreachable FAIL Unexpected error message! #2 unreachable2 FAIL ... Fix it by moving the "all" target to the start of lib.mk, making it the default target.
