* corrected spelling mistakes
README.MacOSX:
* corrected spelling mistakes
README.Platforms:
* changed Android version to match AndroidManifest.xml
README.Porting:
* added missing directories from list
* removed cdrom directories from list
README.android:
* updated required NDK revision
* add project.properties to list
* changed lower limit for to android-10 and removed upper
* added a statement why older devices not supported
* added correct dates to statements about OpenGL ES
* added info about Google's device numbers and date
* corrected spelling mistakes
README.gesture:
* corrected spelling mistakes
README.pandora:
* corrected spelling mistake
README.touch:
* changed that values are no in range 0..1
* updated the names of some functions
* updated the notes about usage
* corrected spelling mistakes
* added info that API changed near original author contact
* 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 __PLATFORM__, where PLATFORM is the name of the OS.
Ideally SDL_platform.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. The "UNIX" way: ./configure; make; make install
If you have a GNUish system, then you might try this. Edit configure.in,
take a look at the large section labelled:
"Set up the configuration based on the target platform!"
Add a section for your platform, and then re-run autogen.sh 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_config.h for your platform. Edit SDL_config.h,
add a section for your platform, and create a custom SDL_config_{platform}.h,
based on SDL_config.h.minimal and SDL_config.h.in
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/stdlib/*.c
src/thread/*.c
src/timer/*.c
src/video/*.c
src/audio/disk/*.c
src/audio/dummy/*.c
src/video/dummy/*.c
src/haptic/dummy/*.c
src/joystick/dummy/*.c
src/main/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!
