[Xenomai-help] Question about 'native skin or CONFIG_XENO_OPT_PERVASIVE' problem

[Benjamin Biegel]

Hello

I am new to the world of patching kernels etc. But i managed to install 
xenomai guided by http://www.xenomai.org/index.php/Xenomai_quick_build_quide

However when trying to execute the ./trivial-periodic i get the 
following error:
'Xenomai: native skin or CONFIG_XENO_OPT_PERVASIVE disabled. (modproble 
xeno_native?)'

I honestly don't know what this indicates. Not even where the 
CONFIG_XENO_OPT_PERVASIVE flag is set.

I use xenomai 2.4.9.1 and linux kernel 2.6.28.9. The pc runs Jaunty and 
is an i686 processor. The installation is made following the guide 
mentioned above.

Any help is appreciated! :)

/Benjamin

The CONFIG_* options are linux kernel configuration options. The message
tells you that if you have compiled the native skin as module, you
should load the module, and that since you want to use it in user-space,
you should enable real-time in user-space, that is the
CONFIG_XENO_OPT_PERVASIVE option.

Nevertheless, the default configuration should have all this. So, if you
did not change the kernel configuration and get this error, could you
show us your kerne boot logs, and kernel configuration?

You are posting here on Xenomai mailing list, a list which will help you
with everything about Xenomai, and a bit more. But answering questions
on this list is already time consuming.

So, I do not have time enough to help you about Linux, but you will find
a lot of information on the web. See for instance:
http://kernelnewbies.org/

And please do always keep the list in copy.
