2 Installation Verification

This chapter is about verifying your installation by performing a few simple tests to see that your system is properly installed.

2.1  UNIX

  • Start Erlang/OTP from the command line,

      unix> erl

    Expect the following output:

      Erlang (BEAM) emulator version 5.0.1 [threads]
      Eshell V5.0.1  (abort with ^G)
      1>
  • Start the GS-based toolbar from the Erlang shell,

      1> toolbar:start().

    and check that the toolbar window pops up.

    Note: The trailing full stop (".") is an end marker for all commands in the Erlang shell, and must be entered for a command to begin execution.

  • Exit by entering the command halt(),

      2> halt().

    which should end both the toolbar window and the command line window.

2.2  Windows

  • Start Erlang/OTP by double-clicking on the Erlang shortcut icon on the desktop.

    Expect a command line window to pop up with the following output,

      Erlang (BEAM) emulator version 5.0.1 [threads]
      Eshell V5.0.1  (abort with ^G)
      1>
  • Start the GS-based toolbar from the Erlang shell,

      1> toolbar:start().

    and check that the toolbar window pops up.

    Note: The trailing full stop (".") is an end marker for all commands in the Erlang shell, and must be entered for a command to begin execution.

  • Exit by entering the command halt(),

      2> halt().

    which should end both the toolbar window and the command line window.
