I've installed 0MQ on a VM running CentOS and I have a C-based application happily working with it. However, I'm unable to get the Java application to work via JZMQ bindings. Here's the error I get:
java -Djava.library.path=/usr/local/lib -jar AidApps.jar receive localhost:9007
Starting the receiver application.
Exception in thread "main" java.lang.UnsatisfiedLinkError: /usr/local/lib/libjzmq.so.0.0.0: libzmq.so.1: cannot open shared object file: No such file or directory

I don't get any errors during installation of either 0MQ or JZMQ. I tried copying all libraries into /usr/local/lib but that didn't solve anything. Any ideas? This works on my Mac (so I know the JAR works), but not on the Linux box.
This is because ld.so cannot resolve your libzmq.so.1.0.0.
Add the path /usr/local/lib to /etc/ld.so.config and run ldconfig to rebuild the cache.
