[Xenomai-help] [Total Newbie] Module xeno_native not found

[Xenomai-help] [Total Newbie] Module xeno_native not found

[Antino Kim]

Hello,

I'm a total newbie in using Linux kernel and Xenomai.
Around 4am, I was able to successfully compile a Xenomai patched
vanilla Linux kernel and install Xenomai! I thought all the trouble
was over...
When I tried running a example program, I got the following error message:


/usr/src/xenomai-2.4.5/examples/native$ ./trivial-periodic
Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled.
(modprobe xeno_native?)

/usr/src/xenomai-2.4.5/examples/native$ modprobe xeno_native
FATAL: Module xeno_native not found.


I will be willing to provide more information if needed, but my gut
feeling tells me it should be a very simple (and obvious) problem to
experienced users. I would really appreciate any help. Thanks.

By default, the native skin is built into the kernel, thus there is no
module.

You may face some issue that Xenomai is unable to work due to kernel
configuration conflicts. Please check the kernel console for messages
regarding Xenomai (dmesg or syslog). If you do not find the reason on
your own, we will need your .config for further help.

Your config shows no sign of Xenomai at all - something went wrong with
your local build. Please read the installation doc carefully and repeat
the described steps. At this chance, select a processor type that is
appropriate for your CPU (CONFIG_M586 is generic, but suboptimal for
many applications)

I basically followed the instruction I found online:

http://www.captain.at/xenomai-installation.php

In short, I did:
Download both vanilla kernel & xenomai
Patched the kernel with xenomai script
Compiled kernel <-- took longest time!
Install xenomai (configure, make all and make install)

Anything that I might have missed? What stage might have gone wrong?

Thanks.

The instructions you may find on internet may not be up-to-date. The
file README.INSTALL, contained in the source you downloaded is always
up-to-date.

Expensive lesson learned. After following README.INSTALL, everything
works just fine. It was just sitting in the source tree, and yet, I
wandered around the web looking for instruction... Thank you all for
your help!
