Hello,

you could try to follow my way of doing it:
http://www.kieltech.de/uweswiki/Xenomai

I did it on Ubuntu, but it should work with Debian, too (the only thing that I don't know
is, whether you need an additional step to update the initial ramdisk after installing
the packages.
Please give feedback, if it works with Debian (and with which version of Debian and
with which additional steps, if any), so that I can add this information to my wiki-page.

I try to answer some of your other questions inline:

Hi,

I am trying to use Xenomai with Debian, but i am kind lost here. Even after reading this: http://www.xenomai.org/index.php/Building_Debian_packages, i could not figure out how to use Xenomai on a Debian with a x86. I am really not experienced with linux kernel.

First of all i have a few questions. If Xenomais is a patch, why should i build a patched kernel? Is it no suposed to patch an already built kernel?

Two possible reasons:
1. I would not try to patch a debian kernel, because it already has a lot of other patches, that could cause conflicts.
I would only patch a native kernel from kernel.org.
2. The newest kernels (which are default on Ubunutu 10.10, I don't know about debian) are not supported by xenomai.

Why there isnt available already built kernels for every architecture?

Building a kernel for xenomai really depends on your hardware. You really have to tweak the .config options, to make it work. A kernel, that works well on one computer might not work well (with a low latency) on another computer. Building generic kernels is hardly possible.

On a final stage i need to use xenomai on a PC104 with an Atom, with no keyboard, Mouse or display, and a debian system with just the baisc packages, a ssh server and Xenomai. What wouldbe the most portable way to use Xenomai so i can replicate that system easily?

On the Web page is said "For development, linux-patch-xenomai and libxenomai-dev are needed, for "production" systems, you should just need xenomai-runtime und libxenomai1 (together with the self built kernel as described in the next section)." What development means? Development of Xenomai itself?

Can any one provide me an explanations for dummies on how to build a debian with xenomai, with a simple explanation on what is being made and why?

Thank you!
