-I haven't updated this document in a while so be aware that some of the information here may be a bit out of date. I wrote this document almost a year ago now, but it still contains useful information about programming in C/C++ for OpenWrt. I recently released Gargoyle, a new web interface for OpenWrt, and I've moved this tutorial onto the official Gargoyle website. My old, website (which was kind of pathetic) is now obsolete, and has been taken down. I apologize for any inconvenience this may cause.+I haven't updated this document in a while so be aware that some of the information here may be a bit out of date.

-This tutorial now makes use of external stylesheets to fit in with the Gargoyle website theme. I realize this may make it more difficult to download and easily reference on your local computer, so I will continue to make the old version of this tutorial available. This version can be found here.+This tutorial now makes use of external stylesheets to fit in with the Gargoyle website theme.

 The OpenWrt SDK for Kamikaze is available only for 64 bit processors. If you're one of us mere mortals who posesses only one of those antique 32 bit processors, you have a problem. You can sometimes get away with using the //White Russian// SDK if you only need your program to run on the MIPS architecture, but the new architectures supported only by Kamikaze require you to use a //Kamikaze// SDK. The solution is to compile the SDK yourself. This is actually fairly simple, provided you have a couple of gigabytes of disk space and an hour or two to spare.  The OpenWrt SDK for Kamikaze is available only for 64 bit processors.
