Running a 32-bit application in Debian Wheezy 64 bits: Missing libraries

Question

I want to play the game Aquaria in a Debian Wheezy 64 bits. The installation went ok, but when trying to play the game I get these errors:

ALSA lib conf.c:3314:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so
ALSA lib control.c:951:(snd_ctl_open_noupdate) Invalid CTL hw:0
AL lib: alsa.c:1000: control open (0): No such file or directory
Message: SDL_GL_LoadLibrary Error: Failed loading libGL.so.1

I have added 32 bit compatibility with dpkg --add-architecture i386 and I think that the required libraries are present in the system since typing locate libasound_module_conf_pulse.so yields:

/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_conf_pulse.so

and locate libGL.so.1:

/etc/alternatives/glx--libGL.so.1-x86_64-linux-gnu
/usr/lib/mesa-diverted/i386-linux-gnu/libGL.so.1
/usr/lib/mesa-diverted/i386-linux-gnu/libGL.so.1.2
/usr/lib/mesa-diverted/x86_64-linux-gnu/libGL.so.1
/usr/lib/mesa-diverted/x86_64-linux-gnu/libGL.so.1.2
/usr/lib/x86_64-linux-gnu/libGL.so.1
/usr/lib/x86_64-linux-gnu/fglrx/fglrx-libGL.so.1.2
/usr/lib/x86_64-linux-gnu/fglrx/libGL.so.1

However, it seems that Debian is ignoring them. What can I do to play Aquaria?

Answer 1

It seems you're missing the 32-bit libraries (/usr/lib/x86_64-linux-gnu contains 64-bit libraries). Now, let's figure out which packages you need for your libraries:

$ dpkg -S /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_conf_pulse.so
libasound2-plugins:amd64: /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_conf_pulse.so
$ dpkg -S /usr/lib/x86_64-linux-gnu/libGL.so.1
libgl1-mesa-glx:amd64: /usr/lib/x86_64-linux-gnu/libGL.so.1

So you need 32-bit versions of these packages:

# apt-get install libasound2-plugins:i386 libgl1-mesa-glx:i386

In general, before you can install any 32-bit libraries, you must add the i386 architecture to dpkg:

# dpkg --add-architecture i386
# apt-get update

Update

Since the above didn't solve the libGL.so.1 issue and it seems from your ldd output that Aquaria can see all its required libraries, I googled the libGL.so.1 error message and two things came up. Please try the following 2 solutions in order:

1. As explained here try symlinking libGL.so.1:

   ln -sv /usr/lib/i386-linux-gnu/libGL.so.1.2 /usr/lib/libGL.so.1
   

   Note that I modified the paths from the answer I linked to so that they're relevant to Debian instead.

2. The answer here suggests that you need to install libgl1-mesa-glx:i386 (which you've already done) plus libgl1-mesa-dri:i386 (which is what I'm suggesting you try next).

Update: What finally worked

apt-get purge libgl1-mesa-glx:i386 
apt-get install libgl1-mesa-glx:i386 
ln -s /usr/lib/mesa-diverted/i386-linux-gnu/libGL.so.1 /usr/lib/i386-linux-gnu/
