-Building DD-WRT from source is quite a daunting task. There isn't much documentation on this process on the official site, although [http://www.cardoe.demon.co.uk/ Peter Cardoe's site] is indeed very helpful. Hopefully expanding on his work will make it an easier process for newbies like me.+#REDIRECT [[Development#Building_DD-WRT_From_Source]]

-=Requirements=+
-To build DD-WRT, you need a Linux machine. It should work on any reasonably modern machine, as long as you have a compiler installed - note that this may not be strictly necessary but I haven't tried it any other way.+
- +
-# The first step is to download the proper source from the [http://www.dd-wrt.com/dd-wrtv2/downloads/index.php?path=sourcecode/ download page] or check it out of the subversion repository at svn://svn.dd-wrt.com/DD-WRT. Should be straightforward.+
-# If you downloaded an archive, unpack it into a directory of your choice by running <tt>tar jxvf FILENAME</tt>. Change to the directory that process creates, probably named "DD-WRT" or something similar.+
-# Download the appropriate toolchain. This is a set of cross-compile tools. Unpack the toolchain wherever, but one suggestion is <tt>/location?/of?/ddwrtdirectory?/toolchain</tt>.+
-# Make a workspace directory and some folders needed by the build process. The name of the "toolchain" directory must be as shown. You may need to be "root" to create the first directory.+
- +
-Here is my work on building DD-WRT. I've created a couple scripts to set up the build environment for you to make life easier on those wanting to create their own builds of DD-WRT.+
- +
-After running these scripts, to build DD-WRT you simply need to:+
- +
- 1. Add your toolchains bin folder to your path environment variable. +
- 2. In DD-WRT/opt run ./install.sh, or ./install_WHATEVER.sh to build only a particular variant.+
- +
-These instructions are valid as of DD-WRT v23 SP2 beta 08/03/06.+
