[Xenomai-help] Ubuntu packages

[Xenomai-help] Ubuntu packages

[C Robinson]

Hi,

I'm seeking some clarification on a few points.   The background is that I have some software I need to install which requires Xenomai on Ubuntu.   Being fairly recent on the Linux scene, following the installation guide for Xenomai has been something of a voyage of exploration, as yet unfinished - and somewhat more complicated as I'm doing this on a bootable usb key.

In any case, a colleague mentioned there was an easier way using the available packages in the Ubuntu repositories, i.e. the xenomai-runtime and associated packages.  It was implied that with a straight-forward 'aptitude install xenomai-runtime' and voila I have a RTOS ready to use.   Given the descriptions of these packages (and no mention of patching of the kernel for example), I don't think that this is their purpose, particularly when I tried downloading the xenomai examples where the second step is :

make XENO=<xenomai-installation-path> KSRC=<xenomai-kernel-source>

Could someone confirm (or refute) this suspicion (that the packages do not provide access to a RTOS) and perhaps explain the intended use of the xenomai packages available on the ubuntu repositories - I've not seen any detailed reference as to why one would download and install these packages (say, in addition to having already gone through the long process of kernel patching + compilation + user space setup).

Thanks for any assistance,
Charles

See:

Please pay attention to the version of the packages available on Ubuntu.
As far as I understood, they are outdated, so, you would probably better
use the Debian package and install them on Ubuntu.

Hi Gilles,

Thanks for the quick response.   I saw this page earlier today, but must have missed the part in brackets, where it says the packages are necessary along with an appropriately patched and compiled kernel. 
  
Also, cheers for the additional tip regarding the use of the Debian packages as opposed to Ubuntu.  I was using a more convoluted approach to the installation, and the one you linked to is appearing much more efficient so far (kernel currently compiling).

Best wishes,
Charles

Sidenote: the kernel patches for 2.6.32/x86 shipped with Xenomai 2.5.4
have a serious issue, which may cause a random lockup during early boot.
You may want to use one of these instead: 
http://download.gna.org/adeos/patches/v2.6/x86/older/adeos-ipipe-2.6.32.15-x86-2.7-02.patch
http://download.gna.org/adeos/patches/v2.6/x86/older/adeos-ipipe-2.6.32.20-x86-2.7-02.patch
