sudo apt-get install libasound2-dev libpulse-dev

Compile

cd build

On Windows:

cmake -G "MSYS Makefiles" ..

Elsewhere:

cmake ..

On Linux, make sure that the cmake log contains the ALSA and the PulseAudio support:

-- Building OpenAL with support for the following backends:
--      PulseAudio, ALSA, OSS, WaveFile, Null

Note: probably that only PulseAudio is really required. Compiling with the ALSA support give us more possibilities to help users having sound issues.

Then:

make -jx
