pcap.h header file problem

Question

anyone know how to fix the problem regarding header file in ubuntu 10.10. I am executing a sniffing program which makes use of this header file. My system shows libcap package

Answer 1

The system won't let me correct Eric Fossum's comment, because I lack reputation. There is a typo ("libcap" vs. "libpcap") and his suggested command should read the following:

sudo apt-get install libpcap-dev
