Yeah, I also met this problem. I guess it may be "testcases/kernel/mem/include/libmem.mk" causing this issue. I can reproduce this fail by following steps: 1, cd testcases/kernel/mem/lib rm libmem.a 2, then back to testcases/kernel/mem/hugetlb/hugemmap make I got the similar error message: make -C ../../../../../testcases/kernel/mem/lib -f "../../../../../testcases/kernel/mem/lib/Makefile" all make[1]: Entering directory `/root/ltp-dev/testcases/kernel/mem/lib' make[1]: ../../../../../testcases/kernel/mem/lib/Makefile: No such file or directory make[1]: *** No rule to make target `../../../../../testcases/kernel/mem/lib/Makefile'. Stop. make[1]: Leaving directory `/root/ltp-dev/testcases/kernel/mem/lib' make: *** [../../../../../testcases/kernel/mem/lib/libmem.a] Error 2 In testcases/kernel/mem/include/libmem.mk: MEM_SRCDIR := $(top_srcdir)/testcases/kernel/mem LIBMEM_SRCDIR := $(MEM_SRCDIR)/lib MEM_DIR := $(top_builddir)/testcases/kernel/mem LIBMEM_DIR := $(MEM_DIR)/lib LIBMEM := $(LIBMEM_DIR)/libmem.a FILTER_OUT_DIRS := $(LIBMEM_DIR) CFLAGS += -I$(MEM_SRCDIR)/include LDLIBS += $(NUMA_LIBS) -lmem -lltp LDFLAGS += -L$(LIBMEM_DIR) $(LIBMEM_DIR): mkdir -p "$@" $(LIBMEM): $(LIBMEM_DIR) $(MAKE) -C $^ -f "$(LIBMEM_SRCDIR)/Makefile" all MAKE_DEPS += $(LIBMEM) See the target $(LIBMEM). Since we have executed make command using the "-C" option, we do not need to specify a make file with relative path. We can just execute like that: $(MAKE) -C $^ -f "Makefile" all in this case. Here the true reason is that when we change directory to $(LIBMEM_DIR), $(LIBMEM_SRCDIR)/Makefile is not a valid path.

This has been fixed by simply removing the relative path to the Makefile since make knows how to find the correct make file itself.

Wouldn't that break out-of-tree build? Because the LIBMEM_DIR is in the build path and the Makefile is in the LIBMEM_SRCDIR?
