You have two problems in this rule (well, three):
$(OBJECTS): $(SOURCES)
$(CC) $(CFLAGS) -c $(SOURCES) $(LIB_PATH) $(LIBS)
You haven’t noticed yet, but the rule makes each object dependent on all sources, and tries to build that way. Not a problem as long as you have only one source. Easy to fix with a static pattern rule and an automatic variable:
$(OBJECTS): src/%.o : src/%.c
$(CC) $(CFLAGS) -c $< $(LIB_PATH) $(LIBS)
Also, the command (“$(CC)…”) doesn’t specify an output file name, so gcc will infer it from the source file name; if you give it src/timeout.c
, it will produce timeout.o
(in the working directory, project/
). So you should specify the desired path to the output file. Easy to do with another automatic variable:
$(OBJECTS): src/%.o : src/%.c
$(CC) $(CFLAGS) -c $< $(LIB_PATH) $(LIBS) -o $@
