: Someone should write a more thorough tutorial! There's still lots of SDL stuff people could port. --[[User:Tantric|Tantric]] 15:34, 24 April 2009 (UTC)
:: As someone who just finished re-writing a great portion of SDL-Wii I think you're a great candidate! ;) Seriously though I would love to see a good tutorial or even just an API reference written. I am madly reading the main SDL tutorial in the hope of figuring out if I can attempt to port the Intellivision emulator jzInTV to the Wii, a programme that thankfully already uses SDL. My biggest problem, aside from never using SDL before, is emulation of the 12+ button keypad. Anyway bring on a good tutorial / reference it would certainly help me in my quest - if I ever really start it. [[User:Ensign R|Ensign R]] 02:07, 1 May 2009 (UTC)
== Image ==
I just managed SDL to work on my wii, and i've made a little program with controller input. I've made it so, that it will show a red background when i push on the right button. What i want is to show a photo when i press the right button. How can i do that? Do I need to include SDL_image? And what's the function i have to use?
Thanks, [[User:GabberNL|GabberNL]] 14:25, 28 April 2009 (UTC)
I used this function:
<source lang="cpp">
SDL_Surface *load_image( std::string filename )
//Temporary storage for the image that's loaded
SDL_Surface* loadedImage = NULL;
//The optimized image that will be used
SDL_Surface* optimizedImage = NULL;
//Load the image
loadedImage = SDL_LoadBMP( filename.c_str() );
//If nothing went wrong in loading the image
if( loadedImage != NULL )
//Create an optimized image
optimizedImage = SDL_DisplayFormat( loadedImage );
//Free the old image
SDL_FreeSurface( loadedImage );
//Return optimized image
return optimizedImage;
And applied the loaded image to a new surface with this function:
<source lang="cpp">
void apply_surface ( int x, int y, SDL_Surface* source, SDL_Surface* destination )
//Make a temporary rectangle to hold the offsets
SDL_Rect offset;
//Give the offsets tot the rectangle
offset.x = x;
offset.y = y;
//Blit the surface
SDL_BlitSurface( source, NULL, destination, &offset );
But when i try to compile it it sais it doesnt have the length of the image. Can somebody help me?

== Cannot compile the template ==
I copied the template and all the sdl includes with the libs and dependencies into the libogc folder. I tried to compile it using programmers notepad.
This is the output:
> "make"
linking ... SDL_template.elf

That question was asked on my SDL Tutorial talk page. I also had that error so I reinstalled Devkit with the older SDL version. How do I update Libogc to the SVN version the right way? So without having this error? [[User:GabberNL|GabberNL]] 17:02, 18 June 2009 (UTC)
:Just do a checkout with this path:<br />It's explain here: -[[User:Crayon|Crayon]] 18:45, 18 June 2009 (UTC)
:Very important is order of libs. If wiikeyboard is before SDL it does not work
Try this:
-lSDL_ttf -lSDL_gfx -lSDL_mixer -lsmpeg -lSDL_image -lfreetype -ljpeg -lpng -lSDL -lz -lfat -lwiiuse -lwiikeyboard -lbte -logc -lm

== SDL_mixer not in the root makefile ==
Had to make / make install it separately - caused me some pain until I figured it out.[[User:Madmanguruman|Madmanguruman]] 02:07, 28 July 2009 (UTC)
== couple of things ==
1) I'm getting an error with devkitPPC_r17-i686-linux.tar.bz2 and SDL Wii
/devkitPPC/bin/../lib/gcc/powerpc-gekko/4.2.4/../../../../powerpc-gekko/include/stdint.h:244: error: conflicting types for 'uintptr_t'
/libogc/include/SDL/SDL_config_minimal.h:39: error: previous declaration of 'uintptr_t' was here
I commented out that declaration in SDL since they are identical
2) the article says to include -lwiikeybord but that library does not seem to be part of latest released libogc (171a?)
3) sdl-config would really be great to have. I can share what I'm using, although I don't include a lot of libraries mentioned in Usage section

== SDL_Mixer: Mix_PlayMusic playback is very slow ==
Hi. I have a strange bug with the SDL_Mixer. When I use the couple of fonction Mix_LoadMUS and Mix_PlayMusic with audio files (Wav or MP3) the SDL lib behaves strangely: All played musics are slowed down and if I whant to get a "good" result I have to increase manualy the pitch of my audio files (+35%)... Someone have an idea ?

: That's not a bug. Your files should be encoded to 32khz or 48khz, the audio port code doesn't handle conversion. --[[User:Tantric|Tantric]] 04:59, 21 October 2009 (UTC)
:: Indeed, it's work fine using 32Khz encoding ! Thank you --[[User:BScrk|BScrk]] 22 October 2009
== sdl_gfx ==
Any chance the sdl_gfx library will ever be fixed for Wii? My program relies heavily on the primitive drawing functions and I'm getting dumps. *sigh* if only sdl_draw supported triangles... [[User:Aeron|Aeron]] 03:20, 6 March 2010 (UTC)
== This Tutorial Is Broken ==
This tutorial no longer seems to work. I'm getting an assortment of errors. Could someone please add version number or file links that are compatible with this tutorial? <small>—Preceding unsigned comment added by [[User:Wiibrew111|Wiibrew111]] ([[User talk:Wiibrew111|talk]] • [[Special:Contributions/Wiibrew111|contribs]]) 20:39, 26 May 2012 (CEST)</small>
I noticed that in the WII SDL page ( ) the gamecube controller support is not documented.
== Gamecube controller support==
It is not documented, but from the code it seems that SDL Wii should support also the gamecube controllers which should be mapped to SDL joystick 4-7 (Wii controllers are mapped to 0-3), the stick axes and the pad are associated as in the Wii classsic controller and the buttons are with this order:
I can not say if the support works since I do not have a gamecube controller to test
[[User:Oibaf|Oibaf]] 1 Jan 2013 (UTC)
There were some bugs in the code. Not it is fixed.
