[erlang-questions] C Nodes Tutorial "erl_publish" error

[by]

Hi,

I am going through this tutorial: http://erlang.org/doc/tutorial/cnode.html <http://erlang.org/doc/tutorial/cnode.html>

Compile steps works, but when I try to run the example with below command:
$ ./cserver 3456

I got this:
erl_publish

$ echo $?
1

Does anyone encounter this before?
Based on the documentation, seems this issue comes from:
  if (erl_publish(port) == -1)
    erl_err_quit("erl_publish");
But what should I do to fix this?

I run this on my Mac computer: macOS Sierra 10.12.6
Erlang version: Erlang/OTP 22.0.1

With kind regards,
Yao
