Hi guys, after building Classpath on Cygwin, I'm now trying to use it in a simple HelloWorld application. As an interpreter, I'm using JC (by Archie Cobbs). When I run: $jc HelloWorld I got the following exception: java.lang.UnsatisfiedLinkError: failed to open native library: 'usr/local/classpath/lib/classpath/libjavanio.so' The reason, I think, is that Classpath doesn't know it's running on Cygwin, therefore it looks for "libjavanio.so" instead of "libjavanio.dll" (which exists on the filesytem). Can anyone help out? thanks for any help, Enrico
