Because test_prog's tests are built with a special rule changing their workdir to the one that contains proper skeleton. Let's just add -I$(OUTPUT) to test_cpp rule instead of adding it to every single .c build rule? If we later still need this, then we should consider adding it widely. > Signed-off-by: Yauheni Kaliuta <yauheni.kaliuta@xxxxxxxxxx> > --- > tools/testing/selftests/bpf/Makefile | 3 ++- > 1 file changed, 2 insertions(+), 1 deletion(-) > > diff --git a/tools/testing/selftests/bpf/Makefile b/tools/testing/selftests/bpf/Makefile > index 1ba3d72c3261..efab82151ce2 100644 > --- a/tools/testing/selftests/bpf/Makefile > +++ b/tools/testing/selftests/bpf/Makefile > @@ -22,7 +22,8 @@ LLVM_OBJCOPY ?= llvm-objcopy > BPF_GCC ?= $(shell command -v bpf-gcc;) > SAN_CFLAGS ?= > CFLAGS += -g -rdynamic -Wall -O2 $(GENFLAGS) $(SAN_CFLAGS) \ > - -I$(CURDIR) -I$(INCLUDE_DIR) -I$(GENDIR) -I$(LIBDIR) \ > + -I$(CURDIR) -I$(abspath $(OUTPUT)) \ > + -I$(INCLUDE_DIR) -I$(GENDIR) -I$(LIBDIR) \ > -I$(TOOLSINCDIR) -I$(APIDIR) \ > -Dbpf_prog_load=bpf_prog_test_load \ > -Dbpf_load_program=bpf_test_load_program > -- > 2.26.2 >
