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 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:)

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

I tried this, still its giving me error fatal error: libpcap/pcap.h: No such file or directory. #include <libpcap/pcap.h> – Vezza

I think you should include it like this: #include <pcap.h> – Florist

sudo apt-get install libpcap0.8-dev

or try sudo apt-get install libcap-dev to better suite your OS's update system – Trigonous

Actually, the original answer is 'correct'. Out the box you may be wanting to install something and just get it to work. If you run sudo apt-get install libpcap0.8-dev then you are good to go, if you don't get the 0.8 bit in there then you'll still be hunting around for where the pcap.h file is and trying to put it into a path somehow. – Fridlund

@EricFossum just for the record - you probably ment libpcap-dev, you have a typo. So I'm leaving this comment to prevent others from dumb cccv like I did – Hybris

Answer 3

If you are using yum, then

sudo yum install install libpcap-devel

Answer 4

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

Answer 5

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.

Answer 6

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

Shouldn't that link have been done automatically? – Matthus

as usual 'yes' but maybe the make script was not configured well then, some conflicts will be happened... – Enmity
