This is not the only instance of the same underlying problem; any test with more than one element in $(TEST_PROGS) fails the same way. Another example: linux# make O=/mnt/linux-build TARGETS=splice kselftest [...] # ./short_splice_read.sh: 15: ./splice_read: not found # FAIL: /sys/module/test_module/sections/.init.text 2 not ok 2 selftests: splice: short_splice_read.sh # exit=1 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).
