First, please stop wasting people's bandwidth with images. When the
error is text, simply cut and paste the text.

Please no private mails.

Second the xeno-test you are running is not xenomai 2.6.1 xeno-test, so
you have binaries of some other version of xenomai version installed,
presumably xenomai 2.5. As explained in the troubleshooting guide, this
is a risky situation.

Try applying the patch. Using xenomai supposes that you are a C
programmer and as such you should already have seen "unresolved
symbols", and that you are familiar with using the common unix tools.

Yes, this too is an issue which has been discussed many times on this list.
