I need help to build zfone from Linux source. As long as anybody is experienced with building and installing an open source software would be able to help. There is no installation instruction available. There is only tar file which I can untar. Then, I don't know anything. Should I just run install or make or what? I am using SUSE 10. This zfone is a voip encryption filter and it makes all the voip call extremely secure. Even if anybody intercepts it nobody in the world can decrypt the calls made applying this filter. Help will be appreciated. Here is instruction that was provided: Notes on how to build Zfone on a Linux platform ----------------------------------------------- Zfone software is (c) Copyright 2006 Philip Zimmermann. All rights reserved. Visit the Zfone home page at http://philzimmermann.com/zfone That page also provides instructions for reporting bugs. This software was developed by Ukrainian developers under contract with Phil Zimmermann. Portions of the software are from open source sources, notably David McGrew's libSRTP, and Brian Gladman's AES implementation. For this beta release of Zfone, you must build it yourself from the source code for your particular Linux platform. We assume most Linux geeks can handle this. In a full release of the product, we'll provide separate pre-built binaries for various linux platforms. Zfone was developed and tested on Gentoo Linux, using gcc 3.3.6. Before installing Zfone you must add support of ipqueue and iptables into your linux kernel. Kernel compile-time options: CONFIG_IP_NF_QUEUE - for ipqueue support CONFIG_IP_NF_IPTABLES - for iptables support After that, install iptables to /sbin/iptables (if you have iptables in another place - create link to /sbin dir.). Then you must install libipq. At this moment libipq.h must be somewhere like /usr/local/include/lipipq/ Then follow these instructions: 1. Go to srtp-1.4.2-aes256ctr, follow instructions in INSTALL there (srtp mast be configured with --enable-aes-256 option) 2. Go to libzfone-1.0.0, follow instructions in INSTALL there 3. Go to zfone-1.0.0 and follow instructions in INSTALL there
