Erlang is not returning anything with spawn

I am learning the basics of erlang from a video in youtube. And I am stuck at one of the video tutorial. This is the code:

say_something(_,0) ->
    io:format("Done ~n");
say_something(Value, Times) ->
    io:format("~s ~n", [Value]),
    say_something(Value, Times-1).

start_concurrency(Value1, Value2) ->
    spawn(easy, say_something, [Value1, 3]),
    spawn(easy, say_something, [Value2, 3]).

The say_something function is ok:

(ErlangProject@Carl-PC)3> easy:say_something("Hello world", 3).
Hello world 
Hello world 
Hello world 
Done 
ok

But, when I run start_concurrency, I don't know what happens, but I don't get what I am supposed to get, as in here:

(ErlangProject@Carl-PC)4> easy:start_concurrency("Hello world", "Really Really").
easy:start_concurrency("Dynamically", "ee").
easy:start_concurrency("dfd", "dfd").

It doesn't return anything. I can just type on and on. What am I doing wrong? Please help me.

Thank you!

Ok, this solved the problem:

  1. I had to change the Erlide plugin location on Eclipse with this plugin location.

This was the original post which helped me. Hope it will help others too!

  • I tried this in 32 bit eclipse.
