Porting

* Porting To A New Platform
|
|
|
|
The first thing you have to do when porting to a new platform, is look at
|
|
include/SDL_platform.h and create an entry there for your operating system.
|
|
The standard format is "SDL_PLATFORM_X", where X is the name of the OS.
|
|
Ideally SDL_platform_defines.h will be able to auto-detect the system it's building
|
|
on based on C preprocessor symbols.
|
|
|
|
There are two basic ways of building SDL at the moment:
|
|
|
|
1. CMake: cmake -S . -B build && cmake --build build && cmake --install install
|
|
|
|
If you have a system that supports CMake, then you might try this. Edit CMakeLists.txt,
|
|
|
|
take a look at the large section labelled:
|
|
|
|
"Platform-specific options and settings!"
|
|
|
|
Add a section for your platform, and then re-run 'cmake -S . -B build' and build!
|
|
|
|
2. Using an IDE:
|
|
|
|
If you're using an IDE or other non-configure build system, you'll probably want to create a custom `SDL_build_config.h` for your platform. Edit `include/build_config/SDL_build_config.h`, add a section for your platform, and create a custom `SDL_build_config_{platform}.h`, based on `SDL_build_config_minimal.h` and `SDL_build_config.h.cmake`
|
|
|
|
Add the top level include directory to the header search path, and then add
|
|
the following sources to the project:
|
|
|
|
src/*.c
|
|
src/atomic/*.c
|
|
src/audio/*.c
|
|
src/cpuinfo/*.c
|
|
src/events/*.c
|
|
src/file/*.c
|
|
src/haptic/*.c
|
|
src/joystick/*.c
|
|
src/power/*.c
|
|
src/render/*.c
|
|
src/render/software/*.c
|
|
src/stdlib/*.c
|
|
src/thread/*.c
|
|
src/timer/*.c
|
|
src/video/*.c
|
|
src/audio/disk/*.c
|
|
src/audio/dummy/*.c
|
|
src/filesystem/dummy/*.c
|
|
src/video/dummy/*.c
|
|
src/haptic/dummy/*.c
|
|
src/joystick/dummy/*.c
|
|
src/thread/generic/*.c
|
|
src/timer/dummy/*.c
|
|
src/loadso/dummy/*.c
|
|
|
|
|
|
Once you have a working library without any drivers, you can go back to each
|
|
of the major subsystems and start implementing drivers for your platform.
|
|
|
|
If you have any questions, don't hesitate to ask on the SDL mailing list:

Enjoy!
