Quick Start - FreeBSD

This guide will help you install and build your first PcapPlusPlus application on FreeBSD in a few simple steps.

1. Step 1 - install PcapPlusPlus
2. Step 2 - create your first app
3. Step 3 - create a Makefile
4. Step 4 - build and run your app

Step 1 - install PcapPlusPlus

Before installing PcapPlusPlus make sure you have the prerequisites installed for FreeBSD.

Pre-compiled packages are available for recent versions of FreeBSD. You can find them under the latest release page. After downloading and extracting the archive file go to: /path/to/your/package/ and run the installation script:

sudo ./install.sh

If you have other versions of FreeBSD you’ll need to build PcapPlusPlus from source. Make sure not to skip the installation part.

Step 2 - create your first app

If you downloaded a pre-compiled package go to: /path/to/your/package/example-app.

If you built it from source go to: /path/to/pcapplusplus/source/Tutorials/Tutorial-HelloWorld.

Make sure you see the following files:

 |-- main.cpp
 |-- 1_packet.pcap

main.cpp is the example application we’ll use.

1_packet.pcap is a pcap file the app reads from.

Step 3 - create a Makefile

If you downloaded a pre-compiled package you can find a Makefile in /path/to/your/package/example-app. This Makefile is already configured.

If you built it from source:

• go to /path/to/pcapplusplus/source/Tutorials/Tutorial-HelloWorld
• rename Makefile.non_windows to Makefile

Step 4 - build and run your app

Run gmake to build the app:

$ gmake

An executable file will be created which contains the compiled app. You can now run it and should be able to see the following output:

Source IP is '10.0.0.138'; Dest IP is '10.0.0.1'
