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.
