Hallo,
ich möchte folgendes Beispiel aus einem "Hand-Tracking-System" namens LeapMotion ausführen.
Ich nutze als IDE IntelliJ und habe die von LeapMotion beiliegende lib eingebunden. Doch leider erhalte ich folgende Fehlermeldung beim Ausführen:
Native code library failed to load.
java.lang.UnsatisfiedLinkError: no LeapJava in java.library.path
Picked up _JAVA_OPTIONS: -Xmx1024M
Process finished with exit code 1
Vielen Dank für eure Hilfe.
