SDL Wii Ports Released

July 31st, 2008, 03:09 Posted By: wraggster

ilidrissiamine has released several new items of interest to wii developers:

This project will introduce many ports of SDL games to the Nintendo Wii and will provide various libraries for SDL developers that extend it.

• SDL_gfx-2.0.17.7z SDL_gfx port to the Nintendo Wii
• SDL_ttf-2.0.9.7z SDL_ttf port to the Nintendo Wii with its Freetype port
• SDL_image.7z Slightly modified SDL_image port to accept various types (libjpeg required)
• libjpeg.7z libjpeg port to the Nintendo Wii

Those are the ones are already on the page. I think that the only reason wraggster made that post was because he saw this wiki page. --vader347 00:19, 1 August 2008 (CEST)

Ah you are right. Somehow I missed the second download link! CarstenK 05:03, 1 August 2008 (CEST)

Example?

Can someone please write an example of how SDL works with devkitpro please? Thanks ahead of time!

Really, there are no many differances with a pc version. Just include devkitppc headers to use with sdl (fat, wiiuse...) Anyway, there is a blue screen exemple, quit with HOME

1. include <stdlib.h>
2. include <time.h>

1. include <SDL/sdl.h>

//#include <SDL/sdl_mixer.h> //#include <SDL/sdl_ttf.h>

1. include <gccore.h>
2. include <wiiuse/wpad.h>

int main(int argc, char** argv) {

   SDL_Surface *screen=NULL;
   srand(time(NULL));

   // initialize SDL video
   if ( SDL_Init( SDL_INIT_VIDEO | SDL_INIT_AUDIO) < 0 )
   {
       fprintf(stderr, "Unable to init SDL: %s\n", SDL_GetError() );
       exit(EXIT_FAILURE);
   }

fatInitDefault(); //for read files (level, serialized structs...) WPAD_Init();

   // make sure SDL cleans up before exit
   atexit(SDL_Quit);
   SDL_ShowCursor(SDL_DISABLE);

   // create a new window
   screen = SDL_SetVideoMode(480, 480, 16, SDL_DOUBLEBUF);
   if ( !screen )
   {
       fprintf(stderr, "Unable to set video: %s\n", SDL_GetError());
       exit(EXIT_FAILURE);
   }

state_in_game(screen);

   return 0;

}

void state_in_game(SDL_Surface *screen) {

   int tick_count=0;
   int tick_trigger=15;

bool done = false;

   SDL_EnableKeyRepeat(10,10);

   while (!done)
   {
       SDL_Event event;

       while (SDL_PollEvent(&event))
       {
           switch ( event.type )
           {
           case SDL_QUIT:
               done = true;
               break;
           }
       }

WPAD_ScanPads();

       u32 held = WPAD_ButtonsHeld(WPAD_CHAN_0); 

if(held & WPAD_BUTTON_HOME){ done=true; }

       tick_count = SDL_GetTicks();
       if (tick_count > tick_trigger)
       {
           tick_trigger = tick_count;
           SDL_FillRect(screen, 0, SDL_MapRGB(screen->format, 0, 50, 150));

           SDL_Flip(screen);
       }   //end thick

   }   //end while

SDL_Quit(); exit(EXIT_SUCCESS); }

Bad libs order ?

I got the following error :

linking ... blastguy_wii_b1.elf i:/usr/devkitpro/libogc/lib\libSDL.a(SDL_gamecube_main.o): In function `main': c:\dev\apps\devkitPro\SDL-Port/src/main/gamecube/SDL_gamecube_main.c:59: multipl e definition of `main' i:/usr/devkitpro/libogc/lib\libfreetype.a(gxvfgen.o):d:/Programming/WiiDev/freet ype-2.3.6/source/gxvalid/gxvfgen.c:444: first defined here i:/usr/devkitpro/libogc/lib\libfreetype.a(gxvfgen.o): In function `main': gxvfgen.c:(.text.main+0xc4): undefined reference to `ft_strncmp' collect2: ld returned 1 exit status make[1]: *** [/i/Documents/developpement/test_sdl_plus_ttf.elf] Error 1 make: *** [build] Error 2

when -lfreetype is included before -lSDL, the right order should be

LIBS := -lSDL_ttf -lSDL_mixer -lSDL_image -ljpeg -lpng -lz -lSDL -lfreetype -lfat -lwiiuse -lbte -logc -lm

Please confime that before make the change on the page.
