error: pcap library not found!

I have tried the following command already:

sudo apt-get install sqlite3 libsqlite3 libsqlite3-dev libcap-dev 

and I got:

Unable to locate package libsqlite3

while all the other packages were installed successfully.

Answer 1

You actually installed libcap-dev when you wanted

 sudo apt-get install libpcap-dev 

Edit: as for libsqlite

 sudo apt-get install libsqlite3-0 

Or you can just do

 sudo apt-get install libsqlite3-dev

Answer 2

You'll need the following packages installed:

sudo apt-get install sqlite3 libsqlite3-dev libpcap0.8-dev

Then try ./configure again and you should be fine

Answer 3

In Ubuntu 14.04 and Ubuntu 14.10, libsqlite3-0, not libsqlite3, is a dependency of reaver, and libpcap0.8 is also a dependency of reaver. In Ubuntu 10.04 and Ubuntu 12.04 there is not a package called libsqlite3, but there is a package called libsqlite3-0. Open the terminal and type:

sudo apt-get install libsqlite3-0 libpcap0.8  

In Ubuntu 14.04 and later, the reaver package is available in the default Ubuntu repositories.

In Ubuntu 12.04 if you run the above command then you will have installed all the dependencies you need to install the reaver package from the Ubuntu 14.04 repositories in Ubuntu 12.04. Visit the Package: reaver (1.4-2) webpage, select the version of reaver that matches your operating system's architecture, and manually download the reaver .deb file. Then double click the reaver .deb file that you downloaded to open it for installation in the Ubuntu Software Center. In Ubuntu 12.04 run the following command to prevent reaver from being automatically installed, upgraded or removed.

sudo apt-mark hold reaver  

Answer 4

On a Debian distro, I used:

./configure --with-pcap-lib=/usr/lib/i386-linux-gnu/ --with-pcap-inc=/usr/include/pcap/

after installing libpcap0.8-dev.

You can check where your actual pcap include and lib sit by using the command:

# dpkg --listfiles libpcap0.8-dev

NB: If you get ./base/pcap-snoop.c:52:21: fatal error: net/bpf.h: No such file or directory, just remove the faulty include.
