Looks like the libs are being found ok.

From the java docs:
http://java.sun.com/j2se/1.3/docs/api/java/lang/UnsatisfiedLinkError.html

------------- quote -------------
public class UnsatisfiedLinkError
extends LinkageError

Thrown if the Java Virtual Machine cannot find an appropriate native-language definition of a method declared native.
------------- end quote -------------

and from the parent class:
http://java.sun.com/j2se/1.3/docs/api/java/lang/LinkageError.html

------------- quote -------------
public class LinkageError
extends Error

Subclasses of LinkageError indicate that a class has some dependency on another class; however, the latter class has incompatibly changed after the compilation of the former class.
------------- end quote -------------

Does this imply that the *order* in which the libs were compiled is an issue?


Anyway, I'm not an expert in this area - it's just a thought.

Good luck,
Ed
