Bug#563885: libsdl1.2debian-alsa: "undefined reference" to deprecated ALSA calls

[John Lindgren]

Package: libsdl1.2debian-alsa
Version: 1.2.13-5
Severity: important

If a try to compile a simple application that uses SDL's sound feature,
such as the following:

        #include <SDL.h>
        
        int main (void)
        {
            SDL_OpenAudio (NULL, NULL);
            return 0;
        }
        

I get the following errors:

        $ gcc -Wall -O2 `sdl-config --cflags --libs` sdl-audio.c 
        /usr/lib/libSDL.so: undefined reference to `snd_pcm_hw_params_set_period_size_near at ALSA_0.9'
        /usr/lib/libSDL.so: undefined reference to `snd_pcm_hw_params_set_periods_near at ALSA_0.9'
        /usr/lib/libSDL.so: undefined reference to `snd_pcm_hw_params_set_rate_near at ALSA_0.9'
        /usr/lib/libSDL.so: undefined reference to `snd_pcm_hw_params_get_channels at ALSA_0.9'
        collect2: ld returned 1 exit status
        
If I uninstall libsdl1.2debian-alsa and install libsdl1.2debian-oss, the
program builds without any errors.

Searching the internet, I found the following email thread which
suggests that the ALSA backend for SDL needs to be updated to keep up
with changes in the ALSA API:
