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.
