pcap.h header file problem

anyone kn开发者_JS百科ow 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 is installed. Still, on compiling the code, an error is coming which reads:

fatal error: pcap.h: No such file or directory compilation terminated.

Please help me out.

Thanks all:)

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

sudo apt-get install libpcap0.8-dev

If you are using yum, then

sudo yum install install libpcap-devel

You don't have the pcap.h file in your include path. You need to add the location of pcap.h to your include path when compiling:

-I/path/to/pcap.h

If you're using linuxbrew, you can just brew install libpcap. In my case I was trying to install nethogs and it failed with this error.

First install libpcap:

sudo apt-get install libpcap0.8-dev

then create its shortcut for header file:

ln -s /usr/include/pcap/bpf.h /usr/include/net/bpf.h
