Default Wordpress menu chapter 4 of book

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'boj_menuexample_settings_page' not found or invalid function name in C:\wamp\www\WPDev\wp-includes\plugin.php on line 470

I am getting above error even though I have file boj_menuexample_settings_page in the directory of the plugin?
