Hi

I have following problem when I compiling my Xenomai Program. It is a
example from the Internet. 
As Attachment I send the programm and the Makefile.

I think the problem is very simple but I have no Idea what it can be. 

My system is
Linux 2.4.25
Xenomai 2.1.1
Adeos 1.0-04

PPC - MPC 8270 on Mircosys PM287.

This is my output:
bash-2.05b# echo $PATH
/usr/xenomai/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/us
r/bin:/usr/X11R6/bin

Try moving the linker flags after the input source file.
i.e. ... -o timer timer.c -L/usr/xenomai/lib -lpthread -lnative
