Just installed elixir the first time and wanted to get right into using it with exzmq. Noticed that the tests fail
elixir -v
Elixir 1.1.1
mix test
......
1) test open a rep socket and wait time out (ExzmqTest)
test/exzmp_test.exs:117

Should remove SASL?
I tried, but I couldn't. There's a lot to fix.
It's unclear whether this is an outdated version of zeromq binding (3.1) or an up-to-date ZMTP implementation.
Hey there,
this might potentially be a noob question, but I've got trouble getting the simplest 'Hello World' example two work.
I've started to read the ZMQ book and wanted to port the examples over to elixir. The code I'm talking about is located here https://github.com/BjRo/zguide/commit/fdcf59738cfa86afd674ff72ee890893a41cf01a
The server seems to start correctly. However when I try to connect a client from a different shell I get this:
* Generic server <0.60.0> terminating
** Last message in was {connect,tcp,{127,0,0,1},5555,[]}
** When Server state == {'Elixir.Exzmq.Socket',<0.2.0>,
{'Elixir.Exzmq.Socket.Fsm.FsmState',
'Elixir.Exzmq.Socket.Req',idle,
{'Elixir.Exzmq.Socket.Req.State',none}},
<<>>,passive,[],none,[],none,[],[],[],[]}
** Reason for termination ==
** {noproc,{gen_server,call,
['Elixir.Exzmq.Link.Sup',{start_child,[]},infinity]}}
** exit {{:noproc, {:gen_server, :call, [Exzmq.Link.Sup, {:start_child, []}, :infinity]}}, {:gen_server, :call, [#PID<0.60.0>, {:connect, :tcp, {127, 0, 0, 1}, 5555, []}]}}

It looks like a missed pattern match in connect
. Is there something obvious I'm doing wrong? Is it the way I start things via mix run -e "Zmq.HWclient.run"
?

When compiling against Elixir 0.13 you get the following compilation error
== Compilation error on file lib/exzmq/link.ex ==
could not compile dependency exzmq, mix compile failed. You can recompile this dependency with `mix deps.compile exzmq` or update it with `mix deps.update exzmq`

The Elixir maintainers apparently weren't happy with the GenFSM wrapper and removed it :-/
