The guidelines are misleading, in the sense that pulling xenomai-head today will download the code for the upcoming 2.6.x release. Unfortunately, changes were made to the rtipc support for 2.6.x, which are not available to 2.5.x. So, building the xenomai-head (2.6.x) examples against headers and libraries belonging to 2.5(.4) won't neither build nor work. Sorry for the time lost fiddling with this. The guidelines were written at a time when -head was actually the development tree for the 2.5.x release. We opened the 2.6.x branch recently, thus becoming the new -head. > > Trying to get up the man pages results in: > > --------------------------------------------------------------------------------------------------------------------------- > clocktest man > The program 'clocktest' is currently not installed.

This defaults to /usr/xenomai if unspecified. Those userland bits should work with any Xenomai 2.5.x kernel support, regardless of whether you got it from the ubuntu/debian repos via apt, or rebuilt it manually, assuming that the distro package was built with sane defaults. If you plan to rebuild your own kernel with Xenomai support instead of picking the one shipped with the distro, then README.INSTALL, ยง2.1 should help. Why this could be a good idea is explained here: http://www.xenomai.org/index.php/FAQs#Tips_and_tricks_setting_up_your_x86_kernel If you go for manual install, I would suggest that you purge all previous Xenomai packages from your system, to avoid hair pulling conflicts. (*) best for x86_32, unless if running pre-Pentium II+ antiques.
