I still do not understand why you are picking up such old versions. When
starting a new development, there is simply no reason to pick an old
version, as you risk to hit and report bugs which have already been
fixed, and waste everybody's precious time.

Anyway, you are not doing things the proper way, as Felipe told you, as
explained in the README.INSTALL file which you can find in the xenomai
tarball, and as explained here:
http://www.xenomai.org/index.php/Xenomai_quick_build_quide

To get xenomai kernel-space support, you have to run the
prepare-kernel.sh script prior to compile the kernel.

If you do not do that, Xenomai user-space support will simply not work.
