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:)

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

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

Pcap and Libpcap Installation Trouble
Hello everyone! I’m new and beginning to learn network protocol concepts.
I am trying to compile a program written in C that has a pcap.h include. When I try to compile it I get the following message:fatal error: pcap.h: No such file or directory
compilation terminated.I have installed libpcap0.8 using the Ubuntu Software Center, but that hasn’t worked. I also tried to download a tar.gz file from the libpcap website, but cannot copy it into the usr/include folder (if it even belongs in there, lol.)
So what I would like is to know a simple to understand method of using pcap.h so that my program will compile correctly. Thank you!

You need to install the development library and header files for libpcap0.8.
Type this in terminal:
Code:
sudo apt-get install libpcap0.8-dev

Question

I am programming a networking tool which uses WinPcap. I am using MS Visual Studio 2008. WinPcap is an external library which I have to use in my programme by including «pcap.h» header.
So i inserted#include <pcap.h>
into my main programme (FYP_2.cpp). I have included the external library directory in my project and i got this error:
Error 1 fatal error C1083: Cannot open include file: 'pcap.h': No such file or directory c:UsersUSERDocumentsVisual Studio 2008ProjectsFYP_2FYP_2FYP_2.cpp 5 FYP_2
By the way, the .lib and .h files are placed in a folder.

There are two requirements: the header and the lib file.
(1) The compiler needs to know where the header is located.
(2) The linker needs to know where the .lib file is located,
and the lib file name.These need to be specified in the Project Properties.
For (1), go to:
Configuration Properties->C/C++->General
and set the path for the header file in
«Additional Include Directories»For (2), go to:
Configuration Properties->Linker->General
and set the path for the lib file in
«Additional Library Directories»Also go to:
Configuration Properties->Linker->Input
and set the lib file name in
«Additional Dependencies»If it still can’t find the header, then change:
#include <pcap.h>
to
#include «pcap.h»

As a first step, see if the project builds if you change
the Project Property:Configuration Properties->General:
«Common Language Runtime support»from
Pure MSIL Common Language Runtime Support (/clr:pure)
to
Common Language Runtime Support (/clr)
