compiled error

error occured while compiling, i got the wrong messages like below:

/tmp/cc4/HK9Z5.o (text+0x16): in function 'main'
:undefined reference to 'SDL_Init'

the command for compilation is : gcc -o sdl sdl.c -W -I /usr/include/SDL
the score code is:

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

main(int argc, char *argv[])
{
if ( SDL_Init(SDL_INIT_AUDIO|SDL_INIT_VIDEO) < 0 ) {
fprintf(stderr, "can't initilize SDL: %s\n", SDL_GetError());
exit(1);
}
atexit(SDL_Quit);
}

thanks in advance.

I haven't used SDL before, but I think using this might make it work:

Code:

$ gcc -o sdl sdl.c -W -I /usr/include/SDL -lSDL

Have a look at the output of:

Code:

$ sdl-config --libs

if it still doesn't work and if that command is available.

You need to link to the SDL library, check the docs for SDL, they should have sample make files.
