The USE_SDL
variable is used to
autoconfigure the dependencies for ports which use an SDL
based library like devel/sdl12
and x11-toolkits/sdl_gui
.
The following SDL libraries are recognized at the moment:
sdl: devel/sdl12
gfx: graphics/sdl_gfx
gui: x11-toolkits/sdl_gui
image: graphics/sdl_image
ldbad: devel/sdl_ldbad
mixer: audio/sdl_mixer
mm: devel/sdlmm
net: net/sdl_net
sound: audio/sdl_sound
ttf: graphics/sdl_ttf
Therefore, if a port has a dependency on
net/sdl_net
and
audio/sdl_mixer
,
the syntax will be:
The dependency devel/sdl12
, which is required by
net/sdl_net
and audio/sdl_mixer
, is automatically
added as well.
If you use USE_SDL
, it will
automatically:
Add a dependency on
sdl12-config to
BUILD_DEPENDS
Add the variable SDL_CONFIG
to
CONFIGURE_ENV
Add the dependencies of the selected libraries to the
LIB_DEPENDS
To check whether an SDL library is available, you can do
it with the WANT_SDL
variable:
