Hi Guys, Better late than never: I checked the nesc.jar requirements in all nesc packages available from http://tinyos.stanford.edu/tinyos/ with the following method: javap -classpath nesc.jar net.tinyos.nesc.wiring.WiringCheck -verbose Based on this: http://en.wikipedia.org/wiki/Java_class_file#General_layout major version 51 means java7, 50 means java6, 49 means java5
All linux packages (rpm x86, rpm x64, deb x86, deb x64) requires java6, but the cygwin package requires java7. So I think we should replace the cygwin nesc package. I already recompiled and tested it, I think it can go to the stanford repo: http://dl.dropbox.com/u/363226/munka/nesc-1.3.4-20121103.cygwin.i386.rpm By the way, I think the the current nesc wasn't really optimized, nesc1.exe is 2.8MB, and in my package it's 760kB.
