Only works in Emqtt #5

Hi,

I wrote a plugin for emqtt that uses ecpool and it works great. Unfortunately, however, it will not work in any standard vm.

Even when only working with Ecpool, regardless of plugins, it will not work outside of emqtt. I download, make, and run erl -pa ebin/ in the ecpool directory, commands such as ecpool:start_pool(poolid, pool_mod, []) do not work, and I receive the error:

exception exit: {shutdown,{failed_to_start_child,pool,
                                                    {noproc,{gen_server,call,
                                                                        [gproc_pool,
                                                                         {new,{ecpool,poolid},random,[{size,4}]}]}}}}

I assume this has to do with some setup that is done in emqtt. Do you happen to know what setup needs to take place in order to use ecpool outside of emqtt?

Thanks,

Problem is that ecpool requires gproc to be running. Solution: application:start(gproc), application:start(ecpool).
