Answer 1

hi i got the answer.. It was not comming as the framework was not included In the Makefile.. By giving the following.. the main.c was compiled

CFLAGS = -Wall -O2 -g

LDFLAGS = -F/System/Library/PrivateFrameworks

LDFLAGS += -framework Apple80211

OBJS = main.o

event_handler: $(OBJS)

gcc $(LDFLAGS) -o event_handler $(OBJS)

clean:

rm -f event_handler

rm -f *.o
