DefinesDefines

This is a list of all the tokens that are being used in a #ifdef or #ifndef in a .cpp or .h file, except for .h files, where tokens used as #ifndef FOO_H or #ifndef FOO_H_ are excluded, as these are almost certainly just include guards. The list is current as of r52922.

No additional filtering has been performed as of yet; some tokens are defined by a platform, while others may not actually be used. Additionally, defined symbols not used in #ifndef or #ifdef are not included at all here.

Defines to be set by/for backends

The following defines are meant to be defined by backend authors, typically in configure (or a custom Makefile). Usually these enable or disable certain features in ScummVM. E.g. a low-powered port might turn off some features that won't work on the target device anyway, to free up some memory.

Defines to configure the backend

Token Defined by Used in Purpose
AUDIO_REVERSE_STEREO configure audio/mixer.cpp Normally, Audio::Mixer produces 16bit signed interleaved (left before right) stereo data. With this define set, it changes the channel order (first right channel, then left).
DATA_PATH
OUTPUT_UNSIGNED_AUDIO audio/rate.h Normally, Audio::Mixer produces 16bit signed interleaved (left before right) stereo data. With this define set, it produces unsigned data instead.
SCUMM_BIG_ENDIAN
SCUMM_LITTLE_ENDIAN
SCUMM_NEED_ALIGNMENT
SCUMMVM_DONT_DEFINE_TYPES
SMALL_SCREEN_DEVICE

Defines to enable usage of external dependencies

Token Defined by Used in Purpose

DYNAMIC_MODULES
PLUGIN_DIRECTORY
PLUGIN_EXPORT
PLUGIN_PREFIX
PLUGIN_SUFFIX

Defines to enable engines or parts of them

The following all are typically defined by config.mak, which is created by running the configure script. They are then used by the build system to enable / disable support for the various engines.

Defines to change user-visible default behaviours

Token Defined by Used in Purpose
FORCE_RTL Makes ScummVM return to the launcher instead of exiting (ideal for ports that take a long while to load). Note that this is a big HACK, in particular, it allows one to return to the launcher from engines / games which do not support this normally for a good reason (such as not being reentrant).
LURE_CLICKABLE_MENUS Makes the Lure of the Temptress' menus clickable instead of hoverable (making them more usable for touchscreens).

Defines to enable common optional features

Token Defined by Used in Purpose
ENABLE_KEYMAPPER
ENABLE_VKEYBD
DISABLE_COMMAND_LINE
DISABLE_FANCY_THEMES
DISABLE_SAVELOADCHOOSER_GRID DISABLE_FANCY_THEMES GUI Disable the thumbnail grid based save/load chooser. This chooser requires a resolution of at least 640x400 and more memory than the list based one.
DISABLE_HELP
DISABLE_TEXT_CONSOLE
DISABLE_TOWNS_DUAL_LAYER_MODE SCUMM FM-Towns games Reduces binary size by removing the FM-Towns dual layer emulation. This removes support for SCUMM v5 FM-Towns games and it might add some glitches to SCUMM v3 FM-Towns games.
USE_HQ_SCALERS
USE_INDEO3
USE_OSD
USE_RGB_COLOR
USE_SCALERS
USE_TEXT_CONSOLE

Defines to enable platform specific optional features

Token Defined by Used in Purpose

Defines to enable emulation of audio devices

Token Defined by Used in Purpose
DISABLE_DOSBOX_OPL
DISABLE_NES_APU
DISABLE_PC98_RHYTHM_CHANNEL PC-98 versions of Legend of Kyrandia 2 and Lands of Lore Reduces binary size by disabling the rhythm channel when emulating certain PC-98 sound cards
