Need help in my SDL window

[Darkinyuasha1]

>///< i feel like a noob having trouble in SDL but
i get an error In function `int SDL_main(int, char**)':
`void SDL_Quit()' cannot appear in a constant-expression
Makefile.win [Build Error] [window.o] Error 1

int main(int argc, char *argv[])
{
   
  if(SDL_Init(SDL_INIT_VIDEO) < 0) {
  fprintf(stderr, "Unable to init SDL: %s\n", SDL_GetError());
  exit(1);
  }
  SDL_Surface *screen;
  
  screen = SDL_SetVideoMode(SCREEN_WIDTH,SCREEN_HEIGHT,SCREEN_BPP,SDL_SWSURFACE);
  if(screen == NULL)
  {
      printf("Unable to set video mode:%s\n",SDL_GetError());
      exit(1);
}

  SDL_WM_SetCaption("Justin's game",0);
 { 
  SDL_Event event;
  
  SDL_WaitEvent(&event);
  
         switch(event.type)
         {
           case SDL_KEYDOWN:
            printf("The %s key was pressed!\n",
                   SDL_GetKeyName(event.key.keysym.sym));
            break;
            case SDL_Quit:
                exit(0);
         }
  
}  
  
  
  
}

oohh i didn't add the includes up in that copy but there cstdlib,cstdio, SDL.h, and the defines for WIDTH,HEIGHT, and BPP :P

Never mind i found the problem it was case SDL_QUIT instead of SDL_Quit XD idiot me

[Darkinyuasha1]

The only problem now is that that window instantly closes

I think you need a variable for the 'game loop'. Declare a variable like:

bool quit = false;

Then put your event handling in a loop that checks whether quit is still false.

while (quit == false)
{
 SDL_WaitEvent(&event);
  
         switch(event.type)
         {
           case SDL_KEYDOWN:
            printf("The %s key was pressed!\n",
                   SDL_GetKeyName(event.key.keysym.sym));
            break;
            case SDL_Quit:
                quit = true;
         }
}

Note how I've changed your SDL_Quit case.

Note how I've changed your SDL_Quit case.

You didn't:

case SDL_Quit:

It should be SDL_QUIT as mentioned.

BTW, you should be calling SDL_Quit() when your program exits. Often this is done by calling

atexit(SDL_Quit);

SDL_WM_SetCaption("<EDITED>'s game",0);

Try not to put that kind of thing on the internet. Now we all know your real name is. At least it's not your full name and phone number . . .

That's considered bad SDL programming practise. Read the SDL Tutorials section of the SDL documentation for why, as I don't remember

Try not to make posts like that, so that if the OP decides to edit his or her post, it's not recorded in your post.

There's nothing wrong with it AFAIK; it's actually in the tutorials. (That having been said, I never use it myself. )

According to the SDL 1.2.9 tutorials, it's "fine for small applications, but should not be used in larger programs". I imagine it's because if your program has crashed so badly that you have corrupted the loaded SDL libraries (Which I _have_ done, BTW) and you try to call SDL_Quit . . . well, lets just say it's not pretty.
