A little probrem in make

cc -o redis-load -pedantic -O2 -Wall -W -lm -pthread -g -rdynamic -ggdb ae.o adlist.o redis-load.o zmalloc.o rc4rand.o utils.o deps/hiredis/libhiredis.a

a litttle mistake with Makefile:
jus put $(CCOPT) end. work ok

redis-load: $(LOADOBJ)
cd deps/hiredis && $(MAKE) static
$(CC) -o $(LOADPRGNAME) $(DEBUG) $(LOADOBJ) deps/hiredis/libhiredis.a $(CCOPT)

redis-stat.o:
$(CC) -c $(CFLAGS) -Ideps/hiredis $(DEBUG) $(COMPILE_TIME) $<

redis-stat: $(STATOBJ)
cd deps/hiredis && $(MAKE) static
$(CC) -o $(STATPRGNAME) $(DEBUG) $(STATOBJ) deps/hiredis/libhiredis.a $(CCOPT)
