Building BPF selftests out of srctree fails with: make: *** No rule to make target '/linux-build//ima_setup.sh', needed by 'ima_setup.sh'. Stop. The culprit is the rule that defines convenient shorthands like "make test_progs", which builds $(OUTPUT)/test_progs. These shorthands make sense only for binaries that are built though; scripts that live in the source tree do not end up in $(OUTPUT). Therefore drop $(TEST_PROGS) and $(TEST_PROGS_EXTENDED) from the rule. The issue exists for a while, but it became a problem only after commitd68ae4982c("selftests/bpf: Install all required files to run selftests"), which added dependencies on these scripts. Fixes:03dcb78460("selftests/bpf: Add simple per-test targets to Makefile") Signed-off-by: Ilya Leoshkevich <iii@linux.ibm.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Link: https://lore.kernel.org/bpf/20230208231211.283606-1-iii@linux.ibm.com
