thx,
i removed rxtx and took the androino 1.0.5 from the web.
now the skech compiles.
now i have the errors
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7
check_group_uucp(): error testing lock file creation Error details:Keine Berechtigungcheck_lock_status: No permission to create lock file.
please see: How can I use Lock Files with rxtx? in INSTALL
But i think that's a problem that i can solve.
