hyperlink - How to link object (.o) file in Eclipse

Question

I'm trying to compile μcOSIII for my board (XMC4500 Relax Kit) but when I try to compile my files I get following output:

'Building target: XMC4500_uCOSIII.elf'
'Invoking: ARM-GCC C Linker'

if I get it right, the files os_core.o and os_cpu_c.o are not linked correctly to the project. I've tried linking these object files by clicking "Properties->C/C++ Build->Settings->ARM GCC Linker->Miscellaneous->Other objects". After compiling again I get to following output:
