erlang - Ejabberd iex live throws 'bad "K" value: \ ' error -

i installed ejabberd correctly( configure --enabled-all) without error. when want run in elixir mode error:

i can run ejabberd server correctly. created user , went well. don't know going wrong.

my config elixir 1.1.1 , erlang r18.

any comment appreciated.

update 1

i didn't pass argument it. did follows:

• download source file , untar it.

• ./autogen ./configure --enable-all make && make install

• everything went well. can run start , stop successfully. can run in live mode(ejabberdctl live).

the problem when run in ejabberdctl iexlive. before download ejabberd i've installed elixir 1.1.1. don't know maybe problem.

update 2

i went through code of ejabberdctl , found problem in line of code:

erlang_opts=" +k $poll -smp $smp +p $erl_processes $erl_options" 

i change

erlang_opts="" 

and worked. don't know make further problem or not. open issue @ repository.

this because $poll variable in +k $poll not initialized correctly. +k flag enables or disables kernel poll functionality erlang vm , acceptable values true or false.

the ejabberdctl shell script has default values $poll , other erlang vm options. uses ejabberdctl.cfg config file , overwrites default values ones included in config file.

you should use ejabberdctl.cfg set desired options uncommenting them follows:

#' poll: kernel polling ([true|false]) # # kernel polling option requires support in kernel. # additionally, need enable feature while compiling erlang. # # default: true # poll=true  #. #' smp: smp support ([enable|auto|disable]) # # explanation in erlang/otp documentation: # enable: starts erlang runtime system smp support enabled. #   may fail if no runtime system smp support available. # auto: starts erlang runtime system smp support enabled if #   available , more 1 logical processor detected. # disable: starts runtime system without smp support. # # default: enable # smp=enable 

this file resides on $ejabberd-installed-path/conf if installed ejabberd manually.
