Requirements

For desired new platforms the following critical items are required:

GCC (cross) compiler to create binary code for the target platform
Linux kernel (version 2.6) with support for target platform
click (modular router) patch (hopefully working on target platform? x86 and mips tested)
Wireless network device supporting to send raw frames (e.g. Atheros cards)

Build software

The build process to get a ready-to-run BRN software package is described in general and examples are made for the Netgear's WGT634U mips platform.

The basic software you will need is a Compiler for the new target platform. If you do not have a running UNIX system on the target platform you will need a cross-compiler, which runs on your development machine (e.g. a x86 Linux system) and creates binary code for the target platform. Read the linked page to get details for the WGT634U.
(optional) Build a Standarized Development Environment.
The Linux operating system controls the execution of all BRN software and provides different device drivers for the hardware components of the target platform. You will need a (cross) compiler to build a Linux kernel. Notice: For some platform you will need extra kernel-patches to get full target platform support!
The most of BRN's functionality is implemented with the help of the click modular router framework. Read how to build the click software for userspace and/or as linuxmodule. /////// brn-patches???
