### creating files for object.o
$(OBJS_DIR):
#mkdir -p $(OBJS_DIR)
and when i check with {make print-C_OBJS} It seems .o file not there

In the makefile
############################Compilation
SRCS_DIR = srcs
OBJS_DIR = objs
But these folders do not exist in your root folder.
Either rename the folders or modify the makefile accordingly.
