SDL_iconvand related functions.
Currently, SDL for RISC OS only supports compiling with GCCSDK under Linux.
The following commands can be used to build SDL for RISC OS using CMake:
cmake -Bbuild-riscos -DCMAKE_TOOLCHAIN_FILE=$GCCSDK_INSTALL_ENV/toolchain-riscos.cmake -DRISCOS=ON -DCMAKE_INSTALL_PREFIX=$GCCSDK_INSTALL_ENV -DCMAKE_BUILD_TYPE=Release cmake --build build-riscos cmake --install build-riscos
When using GCCSDK 4.7.4 release 6 or earlier versions, the builtin atomic functions are broken, meaning it's currently necessary to compile with
-DSDL_GCC_ATOMICS=OFF using CMake. Newer versions of GCCSDK don't have this problem.
The video driver currently provides full screen video support with keyboard and mouse input. Windowed mode is not yet supported, but is planned in the future. Only software rendering is supported.
The filesystem APIs return either Unix-style paths or RISC OS-style paths based on the value of the
__riscosify_control symbol, as is standard for UnixLib functions.
The audio, loadso, thread and timer APIs are currently provided by UnixLib.
The joystick, locale and power APIs are not yet implemented.
