Debian and Ubuntu don't ship a prebuilt xenomai/adeos enabled kernel. You have to patch and build the kernel yourself.

> Bear in mind that my first question to the mailing list was asking if the Xenomai packages available from the repository (i.e. installing xenomai-runtime, linux-patch-xenomai, libxenomai1 ) were sufficient to turn a Ubuntu installation into a Xenomai OS.   I was directed to the Debian installation guide.   This indicated to me that it was necessary to build and install the Debian packages, but in addition it was still necessary to compile a new kernel patched during the process (so I wonder what is the purpose of the linux-patch-xenomai).

Thats still true, you need to install the packages mentioned and a self built kernel.

The testsuite is not installed in /usr/bin/ anymore using debian packages, try:
/usr/lib/xenomai/clocktest

/usr/lib/xenomai/ is not in the search path, you have to use absolute paths.

This is the 'standard' way to install xenomai. Install the debian packages like you did, or use this standard way. But don't mix both.

Looks good.

> Before I follow the steps provided by Philippe, I'm going to try the packages provided in the Ubuntu repository.   I realise these are out of date, but if they allow me to finally ave a Xenomai OS on which I can install the software I will be working with, then I can perhaps have another go later when I have some of my project underway.

Please don't do this, look first at the directory /usr/lib/xenomai/ and call the utils with absolute paths.
