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:)
sudo apt-get install libpcap0.8-dev
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
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.
