| 2 | * Porting To A New Platform |
| 3 | |
| 4 | The first thing you have to do when porting to a new platform, is look at |
| 5 | include/SDL_platform.h and create an entry there for your operating system. |
| 6 | The standard format is __PLATFORM__, where PLATFORM is the name of the OS. |
| 7 | Ideally SDL_platform.h will be able to auto-detect the system it's building |
| 8 | on based on C preprocessor symbols. |
| 9 | |
| 10 | There are two basic ways of building SDL at the moment: |
| 11 | |
| 12 | 1. The "UNIX" way: ./configure; make; make install |
| 13 | |
| 14 | If you have a GNUish system, then you might try this. Edit configure.in, |
| 15 | take a look at the large section labelled: |
| 16 | "Set up the configuration based on the target platform!" |
| 17 | Add a section for your platform, and then re-run autogen.sh and build! |
| 18 | |
| 19 | 2. Using an IDE: |
| 20 | |
| 21 | If you're using an IDE or other non-configure build system, you'll probably |
| 22 | want to create a custom SDL_config.h for your platform. Edit SDL_config.h, |
| 23 | add a section for your platform, and create a custom SDL_config_{platform}.h, |
| 24 | based on SDL_config.h.minimal and SDL_config.h.in |
| 25 | |
| 26 | Add the top level include directory to the header search path, and then add |
| 27 | the following sources to the project: |
| 28 | src/*.c |
| 29 | src/audio/*.c |
| 30 | src/cdrom/*.c |
| 31 | src/cpuinfo/*.c |
| 32 | src/events/*.c |
| 33 | src/file/*.c |
| 34 | src/joystick/*.c |
| 35 | src/stdlib/*.c |
| 36 | src/thread/*.c |
| 37 | src/timer/*.c |
| 38 | src/video/*.c |
| 39 | src/audio/disk/*.c |
| 40 | src/video/dummy/*.c |
| 41 | src/joystick/dummy/*.c |
| 42 | src/cdrom/dummy/*.c |
| 43 | src/thread/generic/*.c |
| 44 | src/timer/dummy/*.c |
| 45 | src/loadso/dummy/*.c |
| 46 | |
| 47 | |
| 48 | Once you have a working library without any drivers, you can go back to each |
| 49 | of the major subsystems and start implementing drivers for your platform. |
