Going down the cygwin path is doable, but it is a path of pain. I strongly recommend using a Linux host. (I personally use Ubuntu, but you should have good success with any disto. Use what you're most comfortable with). The simplest approach to get running with a Linux box is to install either VirtualBox or VMware and create yourself a Linux virtual machine. That will get you up and running without having to obtain new hardware or risk breaking your XP setup. Cheers, g. -- Grant Likely, B.Sc., P.Eng. Secret Lab Technologies Ltd.

Colinux is fairly trivial to get up and running. It gives you real linux running as a process under windows. There is no "virtualization" going on at all. The only caveat is that all access to host hardware must go through windows. This is much less of a big deal than it sounds - if you are talking about a development environment. It is also useful because from colinux running under windows you can have access to your windows filesystem. This means that you can use REAL linux tool fairly transparently on windows while still running windows. I rarely run windows anymore. But when I do I run colinux, and I write linux shell scripts that run under colinux to preform tasks I find difficult to do under windows. -- Dave Lynch DLA Systems Software Development: Embedded Linux 717.627.3770 dhlii@dlasys.net http://www.dlasys.net fax: 1.253.369.9244 Cell: 1.717.587.7774 Over 25 years' experience in platforms, languages, and technologies too numerous to list.

You have to be a masochist to try to build linux kernels under cygwin. It is purportedly doable - I have never succeeded, but very painful. If you must work under windows - I know alot of engineers do, then I would highly recommend colinux. www.colinux.org. It will give you linux and windows running concurrently on the same machine with very little pain, no additional cost, there is a small amount of grief getting windows-colinux networking functioning, that is not critical but it is nice. Getting X windows running is substantially more effort and is very nice - but completely unnecescary. Colinux is a much easier and lighter weight solution than virtualization. That said I would highly recommend you seriously consider doing linux development without windows. The targets you are going to be developing for are going to run linux. The initial learning curve might be steeper, but the payoff is greater. Everything you learn on the development side will apply to the target. There are bazillions of Live CD's you can try. I would highly recommend Ubuntu. Its alot like windows - except mostly friendlier and it works. Personally, I went the roll your own method for creating a development environment. I have no experience with ELDK. Buildroot and many other "environments" dictate a very specific way of working. They guide you to a working solution faster but I find myself fighting against their limitations all too soon. Unfortunately crosstools has not been updated in a while, and does not officially support uClibc (it does support glibc). uClibc is very appealing for limited resource systems. There is a crosstools-ng project, but it does not have ppc support. It would be really really nice (hint) if Xilinx would get their microblaze compiler code into the gcc distribution.
