Hello,
I followed the suggested install procedure to setup a Xenomai kernel on my x86
Ubuntu system.
(http://www.xenomai.org/index.php/Building_Debian_packages)
I would like to verify that everything is hunky-dory, but I'm not quite sure
how. I have read in some places that "user space" needs to be set up,
although this is not mentioned in the reference I followed. Is this still
necessary?
The command:
dmesg | grep Xenomai
Shows:
-------------------------------------------------------------------------------------------------------------
[ 0.659903] I-pipe: Domain Xenomai registered.
[ 0.659928] Xenomai: hal/i386 started.
[ 0.659942] Xenomai: scheduling class idle registered.
[ 0.659944] Xenomai: scheduling class rt registered.
[ 0.660450] Xenomai: real-time nucleus v2.5.4 (Sleep Walk) loaded.
[ 0.660570] Xenomai: starting native API services.
[ 0.660572] Xenomai: starting POSIX services.
[ 0.660599] Xenomai: starting RTDM services.

The command:
xeno-test
Is not quite so promising (there was more of the same text above and below the
output shown below):

I am also attempting to follow the instructions to set up the examples
(http://www.xenomai.org/index.php/Examples). I extracted the examples to:
/usr/xenomai_egs/xenomai-head/examples/
so this would be the directory I would use for the first step. (Although I
notice that I also have something at /usr/share/xenomai/testsuite/unit/)
The second step, I come across the reference to 'user space', the step being:
make XENO=<xenomai-installation-path> KSRC=<xenomai-kernel-source>
I do not need a second argument (since I am in the patched kernel)
but the first argument is the user space directory.
So my next question is to check if the user space (i.e. the XENO variable)
refers to the directory /home/<user name>/xenomai-2.5.4 and if so, is it ok to
use my default user name?
Many thanks,
Charles
