DebugMode
Debug Mode
The game can be built to support debugging by supplying --enable-debug as an argument to configure during the build process. Currently this enables a few code snippets for the benefit of an external debugging tool like gdb, and calls the compiler with -g and -O0 flags. You probably don't want to strip a debugging build, since the symbols are needed for the debugging tool. Note than an unstripped debug build on linux is over 80MB, compared to 2-3MB stripped. It is a good idea to run a debug build of the game if you do development, since it can be necessary to diagnose serious problems.
Running the game with commandline option --debug or -d enables debug mode within the game. This works whether --enable-debug was used to build the game or not. Debug mode displays additional information, and enables context menu options to create units and changing unit sides. Debug mode can also be enabled within the game using :debug (see CommandMode), and on Mac versions of the game, by holding down the Option key when starting Wesnoth.
Debug mode is disabled when you play a network multiplayer game.
Debug mode also enables some additional commands in CommandMode.
Debug mode also adds a new context menu item: right click and select 'Create Unit' and you will be able to create any unit anywhere on the map. You can then use the :unit command to set the unit's attributes (see CommandMode).
