[erlang-questions] running debugger fails

[weoccc]

Hi,

I am new to erlang and I am running mongooseIM app and want to do some
debugging on local server.

I tried to follow the tutorial as show here :
http://www.erlang.org/doc/apps/debugger/debugger_chapter.html

but get some error:

Erlang/OTP 17 [erts-6.2] [source] [64-bit] [smp:8:8] [async-threads:10]
[kernel-poll:false]

Eshell V6.2  (abort with ^G)
1> debugger.start().
* 1: syntax error before: '.'
1> debugger:start().
{error,{undef,[{wx,new,[],[]},
               {dbg_wx_mon,init,3,[{file,"dbg_wx_mon.erl"},{line,113}]}]}}

Any idea how to fix those ?

Thx,

Weide
