Do you have the same problem if you run make install and run the
installed latency?

You are trying to compile xenomai-head examples with xenomai 2.6. This
will not work. You should try and compile xenomai 2.6 examples. Please
pick them from the git repository as the makefiles were broken in
xenomai 2.6.0 as well. Alternatively, you can apply the following patch:
http://git.xenomai.org/?p=xenomai-2.6.git;a=commitdiff;h=689e0433ab907958f162181d9b8c3b49012dd67a;hp=b10443b256dcc57a6a200572def4adda567d473a

It is the makefiles fault: the xeno-config usage has changed in xenomai
2.6. So, you should, as I already told you in three separate mails,
some of which even private, run xeno-config --help to understand the syntax.

The next time you ask the same question, you will either be flamed, or
simply ignored, depending on my mood at the time.
