I am trying to use logstash with the zeromq input plugin. Whenever I start logstash with my configuration, I get the following error: > Unable to load this gem. The libzmq library (or DLL) could not be found. > If this is a Windows platform, make sure libzmq.dll is on the PATH. > If the DLL was built with mingw, make sure the other two dependent DLLs, > libgcc\_s\_sjlj-1.dll and libstdc++6.dll, are also on the PATH. > For non-Windows platforms, make sure libzmq is located in this search path: Here there is a long list of paths, including the following: > ["[...]/elk/logstash-2.3.3/vendor/bundle/jruby/1.9/bin/libzmq.so", [...]] I added a symlink with the above name that points to a libzmq.so that can be found in another directory. (Note that I have no root access.) This, however, did not solve the problem, and I keep getting the same error whenever I launch logstash with my config. Any ideas how to fix this? (for reference, here is the same error posted on github: [Issue trying to run zmq for logstash-shipper · Issue #2426 · elastic/logstash · GitHub](https://github.com/elastic/logstash/issues/2426)) ---
