Hello !

is this right command for getting SDL?

Call sudo make uninstall in your own compiled SDL version to remove it from the system (Maybe you have already done that !)
You have to install one of these packages :

apt-get install libsdl1.2debian

This is only a meta package.
You need to install either one of these packages :

dep: libsdl1.2debian-alsa (= 1.2.14-6.1)
    Simple DirectMedia Layer (Grafikbibliothek, mit Unterst?tzung von X11 und ALSA) 
oder libsdl1.2debian-all (= 1.2.14-6.1)
    Simple DirectMedia Layer (with all available options) 
oder libsdl1.2debian-esd (= 1.2.14-6.1)
    Simple DirectMedia Layer (mit X11 und esound Optionen) 
oder libsdl1.2debian-arts (= 1.2.14-6.1)
    ?Simple DirectMedia Layer? (mit X11 und aRts-Optionen) 
oder libsdl1.2debian-oss (= 1.2.14-6.1)
    Simple DirectMedia Layer (mit X11- und OSS-Optionen) 
oder libsdl1.2debian-nas (= 1.2.14-6.1)
    Simple DirectMedia Layer (with X11 and NAS options) 
oder libsdl1.2debian-pulseaudio (= 1.2.14-6.1)
    Simple DirectMedia Layer (with X11 and PulseAudio options)

sudo apt-get install libsdl1.2debian-alsa
or
sudo apt-get install libsdl1.2debian-pulseaudio

whether you use ALSA or PulseAudio.

sudo apt-get install libsdl1.2-dev

This will install a bunch of packages to your system.

After all is installed correctly, when you call which sdl-config,
it should show you something like

/usr/bin/sdl-config

RLEAlphaSurface executes RLE compress, compress will use map->dst of
surface.

static int RLEAlphaSurface(SDL_Surface * surface)

{

   SDL_Surface *dest;

   SDL_PixelFormat *df;

   ...

   dest = surface->map->dst;

   if (!dest)

          return -1;

   df = dest->format;

   ...

}

But surface->map->dest maybe invalid!

RLEAlphaSurface is used for tow scenario, one is blit, other is
SDL_UnlockSurface. In blit, surface->map->dst always valid. But in
SDL_UnlockSurface, dst maybe invalid. Let see a sequence

A is RLE surface. A blit to destination surface C. When blit finished,
A’s map->dst point to C.
C is released. But don’t update A’s map->dst.
Program wants access A’s pixel data directly, so call
SDL_LockSurface/SDL_UnlockSurface. When execute SDL_UnlockSurface, because
surface->map->dst is invalid, result to crash.

Is it a BUG? or I mistake RLEAlphaSurface?
