CooIDE - Ethernet (Projekt Build - Error)

Moin,

Ich hab auf meiner Hardware einen LPC1768 + DP83848 und versuch das 
ganze zum laufen zu bringen. (Ethernetverbindung...)
Dafür hab ich mir das Beispiel von 
http://www.coocox.org/forum/viewtopic.php?t=5007&f=9 runtergeladen. (Da 
werden die gleichen Komponenten verwendet)

Hab das ganze also in meinen Workspace kopiert und siehe da es 
funktioniert nicht. (BUILD FAILED - [cc] collect2.exe: error: ld 
returned 1 exit status) Hab das ganze im CooCox-Forum gepostet ( 
http://www.coocox.org/forum/viewtopic.php?f=9&t=5184 ) und den Hinweis 
bekommen "don't forget to add the C Library code component"
Hab ich gemacht Configuration -> Link -> Options: "Use base C Library"

Muss ich die sonst noch irgendwie einbinden?
Überseh ich irgendwas grundliegendes?


Gesamte Ausgabe nach Build ist:
