SDL and Angstrom

Hi.

Can anybody help me to install SDL on Angstrom?

I use an Angstrom Image from the “http://www.angstrom-distribution.org/
narcissus/“page (it’s like the demo image) and would like to use SDL.

If I include "#include <SDL.h>" the gcc can't find the library.

Is it possible to install SDL with opkg? I can use internet and I can
cross-compile it with “open embedded”.

How should I install SDL?

hi,

you can install SDL using opkg. i am not sure of the exact command but
what does
'opkg list | grep sdl' give as output?

Thank you Deepak Narayan.

After running:
  opkg list | grep libsdl
I saw the packages I had to install.

I can compile programs using the SDL library.
Now I have other problems.

I can run the SDL program on the x11-image but not on the console-
image.

Source code:

#include <stdlib.h>
#include <SDL.h>

int main(int argc, char *argv[])
{
  //Deklaration
  SDL_Surface *screen;

  //Initialisierung
  if( SDL_Init(SDL_INIT_VIDEO) == -1)
    {
      printf("Can't init SDL: %s\n", SDL_GetError());
      exit(1);
    }
  atexit(SDL_Quit);

  screen = SDL_SetVideoMode(1024, 768, 0,0);
  if( screen == NULL )
    {
      printf("Can't set videomode: %s\n", SDL_GetError() );
      exit(1);
    }
  SDL_Delay( 3000 );
  SDL_Quit();

  return 0;
}

I have no compiler errors or warnings.

If I try to run it, it tells me “Can’t set videomode: No Videomode
large enough for 1204x720”.

With an x11-image I can run this program and open a bmp- or png-image.

If anyone can run SDL software with console-image please help me.

Thanks and regards,
Alexej

try
screen = SDL_SetVideoMode(0, 0, 0,0);
to let SDL select the best resolution. Since the graphics driver
(framebuffer) under the
console image does not support changing resolutions at run time (as
far as I know),
you should use the resolution that the driver is using (set in u-boot
boot args)

Hi

I tried to run screen = SDL_SetVideoMode(0, 0, 0,0); but I have the
same error:

Can't set video mode: No video mode large enough for 1204x720

Do you have other ideas what kind of problem it is?
