problems with SDL

I'm using linux debian and i've installed SDL (1.2.something). When I try to compile the .c file like this:

gcc -o file -lSDL -lpthread file.c

I get errors: undefined reference to 'SDL_Init'
undefined reference to 'SDL_Quit'

file.c:

#include <stdio.h>
#include <SDL/SDL.h>

int main(int argc, char *argv[])
{
if (SDL_Init(SDL_INIT_VIDEO) < 0) { printf("error"); exit(1); }
atexit(SDL_Quit);
}

Why doesn't it work?

I think its not finding your SDL.h. SDL/SDL.h might not be in your standard include path?

For fun, change:

#include <SDL/SDL.h> with

#include "full path to SDL include files here/SDL.h"

and see if that changes anything...if it does then you have to somehow add your SDL includes to your include path
(I have no idea how to do this tho...I'm just starting to program in linux)

actually, libSDL requires a few more compiler and linker directives than the ones you've stated. you should be compiling your files with the following line:

gcc -o file file.c `sdl-config --cflags --libs`

note: ` is not a ', it's a `
