I'm using JRuby 1.7.12

Reproducing the error:

What version of zeromq do you have installed?

2.20

cmouse commented 10 years ago

I have this issue too, apparently ffi-rzmq does not check during compile time which API it should use. There is a difference between 2.x and 4.x about the naming of few functions that should be checked.

chuckremes commented 10 years ago

ffi-rzmq 1.x doesn’t really support libzmq 2.x anymore. Zeromq has moved very fast from 2.2 to 3.2 to 4.0 that the gem no longer tries to support everything.

If you cannot upgrade libzmq to 4.x, then I suggest using an older version of the gem to get 2.x support.

@chuckremes Do you have any idea as to which older version of the gem is compatible and stable?

chuckremes commented 10 years ago

The last release to support 2.x was probably 1.0.3.
