Hi
I have succedded to fix synaptic (and apt-get) and install SDL.
I compile and run the file, but it produce nothing when I move mouse or
type key (it types letter, but not the message printf should output)
But I don't know exactly how I should call the functions...!!!

Anything I should try ?

My target is to debug a keyboard not working with pygames on a ARM
platform.  I was suggested to make this little programe to debug this issue.

bellow is my code

Thanks

#include <stdio.h>
#include <stdlib.h>
#include "/usr/include/SDL/SDL.h"

int MySDL_WaitEvent()
{
    printf("About to call SDL_WaitEvent(&event)\n");
    SDL_Event event;
    SDL_WaitEvent(&event);

    switch (event.type)
    {
        printf("In switch/case of SDL_WaitEvent(&event)\n");
        case SDL_KEYDOWN:
            printf("The %s key was pressed!\n",
                SDL_GetKeyName(event.key.keysym.sym));
            break;
        case SDL_QUIT:
            exit(0);
    }
}


int MySDL_PollEvent()
{
    printf("About to call SDL_PollEvent(&event)\n");
    SDL_Event event;
    while ( SDL_PollEvent(&event) )
    {
        switch (event.type)
        {
            printf("In switch/case of SDL_PollEvent(&event)\n");
            case SDL_MOUSEMOTION:
                printf("Mouse moved by %d,%d to (%d,%d)\n",
                    event.motion.xrel, event.motion.yrel,
                    event.motion.x, event.motion.y);
                break;
            case SDL_MOUSEBUTTONDOWN:
                printf("Mouse button %d pressed at (%d,%d)\n",
                    event.button.button, event.button.x, event.button.y);
                break;
            case SDL_QUIT:
                exit(0);
        }
    }
}

int main(int argc, char *argv[])
{
    printf("About to call SDL_Init()\n");
    if ( SDL_Init(SDL_INIT_AUDIO|SDL_INIT_VIDEO) < 0 )
    {
        //fprintf(stderr, "Unable to init SDL: %s\n", SDL_GetError());
        printf("Unable to init SDL: %s\n", SDL_GetError());
        exit(1);
    }
    while(1)
    {
        printf("About to call MySDL_PollEvent()\n");
        MySDL_PollEvent();
        printf("About to call MySDL_WaitEvent()\n");
        MySDL_WaitEvent();
    }   //  while

    printf("About to call atexit()\n");
    atexit(SDL_Quit);
}
