I want to run small code with xenomai. I used this page to compile kernel
and install xenomai.
http://www.stanley.gatech.edu/skelly/uncategorized/installing-xenomai-on-ubuntu-12-04/#comment-3379
I didn't change configuration options.When I run "sudo
./trivial-periodic",the output is Xenomai: /dev/rtheap is missing
(chardev, major=10 minor=254).
In this question, xenomai 2.6.0 was recommended -> .
http://www.xenomai.org/pipermail/xenomai/2011-October/024664.html
And I use xenomai 2.6.2.

Please:
- use the latest stable version, that is Xenomai 2.6.4
- follow the installation instructions here:

My PC is Ubuntu 12.04. This tutorial is for debian. Some commands contain a
"debian" word.Should I replace "ubuntu"?

ubuntu is a derivative of debian. The debian instructions should work
just fine.
Please do not top-post.

I installed xenomai 2.6.4 and linux kernel 3.14.17 without any error using
below guide.
http://xenomai.org/2014/06/building-debian-packages/#Building_a_Xenomai_patched_Linux_kernel_package
Kernel Configuration :
* `Real-time sub-system`
* ENABLE `Xenomai`
* `Power management and ACPI options`
* `ACPI (Advanced Configuration and Power Interface) Support`
* DISABLE `Processor`
* `CPU Frequency scaling`
* DISABLE `CPU Frequency scaling`
* `Processor Type and Features`
* SET `Processor family`
Processor family is x86. "uname -a"'s command output is
"3.16.0-031600-generic #201408031935 SMP Sun Aug 3 23:36:11 UTC 2014
x86_64 x86_64 x86_64 GNU/Linux"
After these steps, is the xenomai ready for use? When I run below code, the
output was there.
$/usr/share/libxenomai-dev/examples/native/
$sudo make
$sudo ./trivial-periodic
Xenomai: /dev/rtheap is missing
(chardev, major=10 minor=254)

You applied the 3.14.17 patch to a 3.16.0 kernel? I would imagine a
lot of work to make that happen.

Well either you are not running the xenomai enabled kernel at all,
or you made it a module and did not load the module yet.

There are other options to change. I already gave you the link to
the page with the list. Besides, the reliable way to refer to options
is by their name in the .config, the particular positions in the
menus changes over time, the config options names are stable.

So, you patched a 3.14.17 kernel, uname tells you that you are
running a 3.16.0 kernel and you you need to send a mail to the
xenomai mailing list to ask what you did wrong. Seriously?

As I already told you, and as is documented in the installation
instructions, the first program to run to check that Xenomai works
correctly is the latency test (but I guess you would get an error
with latency too, if not running on a Xenomai patched kernel).

There are below i-pipe verison under Xenomai 2.6.4 patches folder. So, I
installed kernel 3.14.17.
ipipe-core-3.10.32-x86-4.patch
ipipe-core-3.8.13-x86-4.patch
ipipe-core-3.14.17-x86-4.patch

The point the previous posters are trying to make is that you did _*build_*
the 3.14 kernel, but you apparently aren't _*running_* it (which is what
'uname' tells you, BTW the build date is there as well, Aug. 3, a dead
giveaway). You are just rebooting into your original 3.16 kernel which has
no Xenomai support of course.
If you can't spot this right away, I'm afraid you may not be ready for this
yet and I would advise you to get acquainted with building a Linux kernel
from kernel.org first (and selecting that kernel to boot) before even
attempting to patch it.
Most importantly, by 'getting acquainted' I mean that you should thoroughly
understand what you are doing and not just follow steps from an online
guide.
J.
