Config emacs + erlang for wxErlang usage

Question

Hello Erlang requires -smp for using wxErlang. As I edit and compile with emacs, I modified the erlang.el file like this: (defvar inferior-erlang-machine-options '("-smp")

But this has no effect when I run the program: WX ERROR: SMP emulator required** exception error: not_smp

Do you see a syntax error or anything else ?

(defvar inferior-erlang-machine-options '("-smp")) hangs emacs — Bertaud, Nov 30 '10 at 16:15

The -smp option requires an argument (enable, disable or auto). If you always want to start an SMP-enabled emulator, add the following to your ~/.emacs file:

 (add-hook 'erlang-mode-hook
     (lambda ()
         (setq inferior-erlang-machine-options '("-smp" "enable"))))

I discovered with your example that the inferior-erlang-machine-options is redefined in .emacs ! – Bertaud Nov 30 '10 at 17:39

(setq inferior-erlang-machine-options '("-sname" "emacs" "-smp" "enable")) – Bertaud Nov 30 '10 at 17:40
looks like it's correct, but don't forget to reverse your edits to `erlang.el` – Felix Lange Nov 30 '10 at 17:42
I don't have anymore the error BUT the program doesn't display a window – Bertaud Nov 30 '10 at 17:49
sorry, i can't help you with that. please make sure you have installed all required libraries. try `wx:demo()`... – Felix Lange Nov 30 '10 at 17:54
You suggest wx:module_name() instead of module:start(). – Bertaud Nov 30 '10 at 17:57
I think I have all required libraries because with "werl -smp" the program runs ! – Bertaud Nov 30 '10 at 18:02
i suggested to try running `wx:demo().`, because it's defined in the wx module. i don't have any experience with wxerlang on windows, sorry. – Felix Lange Nov 30 '10 at 18:06
