crackle installation problem

[blakroot]

I am not able to install the crackle.
`blackroot@blackroot:~/Desktop/crackle-master$ make

cc -O2 -Wall -Werror -g -c -o crackle.o crackle.c

In file included from crackle.c:38:0:

crackle.h:5:18: fatal error: pcap.h: No such file or directory

compilation terminated.

: recipe for target 'crackle.o' failed

make: *** [crackle.o] Error 1

maybe you need pcap library.
try:
sudo apt-get install libpcap-dev
