MicroC OS-II

I'm trying to get MicroC/OS-II version 2.52 running on a ATxmega128A1.
But I keep getting linker errors and I don't know what else I could do 
to fix them.

Here is the Linker Output:

But the OSxxx() functions are defined in the header file "uCOS_II.H" 
which is included in test.c.
And I'm building all the necessary .c files which include the 
declarations(? My english ain't the best) for those functions.
I even checked the .map file and the links for those functions are in 
that file. I attached the .map file.
I got the CPU-Port from micrium.com.
