If you are writing some packet sniffing code using libpcap on Ubuntu Linux, there are higher chances you may get an error like below, during the first compilation.

sniffer.c:1:18: fatal error: pcap.h: No such file or directory
compilation terminated.

Solution :

The above error shows we are missing pcap.h in current development environment, for installing this header, use below command

 $ sudo apt-get install libpcap-dev
