Thanks Cyril, Before you told me this, I tried to deleted all -O2 in include/mk/config.mk and include/mk/config.mk.in, then make. I just wanted to know if there are some simple parameters likes "DEBUG=DDEBUG" for make. Now I set CFLAGS before configure and modify include/mk/config.mk after configure is useful.
