From: Shuah Khan Date: Wed, 1 Mar 2017 22:15:07 +0000 (-0700) Subject: selftests: lib.mk Fix individual test builds X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e53aff45c490ea04aa5d9e3cffa65b6b54397455;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git selftests: lib.mk Fix individual test builds In commit a8ba798bc8ec ("selftests: enable O and KBUILD_OUTPUT"), added support to generate compile targets in a user specified directory. OUTPUT variable controls the location which is undefined when tests are built in the test directory or with "make -C tools/testing/selftests/x86". make -C tools/testing/selftests/x86/ make: Entering directory '/lkml/linux_4.11/tools/testing/selftests/x86' Makefile:44: warning: overriding recipe for target 'clean' ../lib.mk:51: warning: ignoring old recipe for target 'clean' gcc -m64 -o /single_step_syscall_64 -O2 -g -std=gnu99 -pthread -Wall single_step_syscall.c -lrt -ldl /usr/bin/ld: cannot open output file /single_step_syscall_64: Permission denied collect2: error: ld returned 1 exit status Makefile:50: recipe for target '/single_step_syscall_64' failed make: *** [/single_step_syscall_64] Error 1 make: Leaving directory '/lkml/linux_4.11/tools/testing/selftests/x86' Same failure with "cd tools/testing/selftests/x86/;make" run. Fix this with a change to lib.mk to define OUTPUT to be the pwd when MAKELEVEL is 0. This covers both cases mentioned above.
