Compiling the OpenAL library

OpenAL is a cross-platform audio library used in many gaming engines. Here are some notes on how to build it for Android.

Getting ready

Download the source code of the Martins Mozeiko port from his page: http://pielot.org/2010/12/14/openal-on-android/.

The home page of the library is as follows: http://github.com/AerialX/openal-soft-android.

How it works…

The minimalistic source code to initialize and deinitialize OpenAL looks as follows:

ALCdevice* Device = alcOpenDevice( NULL );
ALCcontext*...
