Description

When trying to run Observer (an application built into Erlang/OTP used to get info about the running BEAM VM) from the Erlang or Elixir command line you get the following error:

20:55:13.694 [error] ERROR: Could not find 'wxe_driver.so' in: /usr/lib64/erlang/lib/wx-1.8.1/priv

{:error,
 {{:load_driver, 'No driver found'},
  [{:wxe_server, :start, 1, [file: 'wxe_server.erl', line: 65]},
   {:wx, :new, 1, [file: 'wx.erl', line: 115]},
   {:observer_wx, :init, 1, [file: 'observer_wx.erl', line: 98]},
   {:wx_object, :init_it, 6, [file: 'wx_object.erl', line: 372]},
   {:proc_lib, :init_p_do_apply, 3, [file: 'proc_lib.erl', line: 247]}]}}

Installing wxwidgets does not help. It seems that the wx libs must be on the system when erlang is compiled in order for this to work.

Looks like we need to recompile it against wxwidgets.

Is this still an issue? We've compiled and updated elixir and erlang several time since this post.

@JoshStrobl - Issue is still present, as @DataDrake said I think the package (probably Erlang itself) must be built against wxwidgets.
