[Tinyos-help] Problem with Listen.java

[Ajit Karthik Mylavarapu]

javac Listen.java is fine. However, I am having this problem with Listen.java:

$ java net.tinyos.tools.Listen
Exception in thread "main" java.lang.UnsatisfiedLinkError: NativeSerial_read
        at net.tinyos.comm.TOSCommJNI.NativeSerial_read(Native Method)
        at net.tinyos.comm.NativeSerial.read(NativeSerial.java:65)
        at net.tinyos.comm.TOSSerial$ReadThread.flush(TOSSerial.java:59)
        at net.tinyos.comm.TOSSerial.<init>(TOSSerial.java:177)

        at net.tinyos.packet.Packetizer.open(Packetizer.java:114)
        at net.tinyos.tools.Listen.main(Listen.java:64)

I dont know why this is occuring. I am sure that the MOTECOM variable
is set to the correct value. I am running on Cygwin under Windows XP.

Any help will be greatly appreciated.

Thank you,
Ajit.
