[Xenomai-help] Problems linking a custom vxWorks application

[Niklaus Giger <niklaus.giger@domain.hid>]

Hi

I update to the latest xenomai/trunk (revision 207) and compiled and installed 
without problems xenomai for my PPC405 board (using busybox).

The kernel starts (using a NFS root) and I can login without major problems. 
Tools like xeno-load and xeno-test do not work as there is no /bin/bash 
around. I usually work around this problem by calling insmod and alike 
manually. 

In xeno-load I also remarked that 
prefix="/mnt/data.ng/hcu/rootfs/usr/xenomai" 
points to the mount point while compiling/installing xenomai, but not to the 
mount point after starting the target (where / 
equals /mnt/data.ng/hcu/rootfs).

My real problem is that I cannot link my custom UVM application, as I get the 
following error. Here are as the complete calls to compile (only the last 
file) and link the application:

What is wrong with this?

Thanks you in advance for your help.
