Probleme mit Hard Floats bei CoIDE/ ARM GCC?

Hallo,
ich versuche gerade ein Projekt von Atollic True Studio auf die CoIDE 
umzubauen bzw. zu portieren. Bis jetzt scheint es auch alles zu klappen, 
bis auf das ich in Atollic die Funktion sqrt(..) nutzen konnte und in 
CooCox nicht bzw. funktioniert diese nur, wenn ich Softfloats verwende. 
Bei Hardfloats gibts folgende Fehlermeldung/en :

       [cc] C:\Users\Ingo Lührig\Desktop\CoIDE Test/Funktionen.c:229: 
undefined reference to `sqrt'

Das undefined reference zu sqrt macht mich stutzig, da sie Funktion 
vorhanden ist und mit der Math.h auch eingebunden ist. Schalte ich um 
auf SoftFloats geht es, warum auch immer. Kann mir jemand helfen?
