[zeromq-dev] Re : Massive problems running ZMQ on android

[Victor Perron]

OK, that's some progress. I doubt you really need ia32-libs for anything
though, but whatever.

You're not supposed to add the System.loadLibrary() call by yourself as
ZMQ.java does it already.

And about the last issue, the ""FATAL EXCEPTION: main,
java.lang.NoClassDefFoundError: org.zeromq.ZMQ" makes me think that your
classpath is not *that* well set. But that is no more of my business, I
guess ;)
