Re: Compile sndio as static library

Hi Jan,

It does. See source code:
https://github.com/ratchov/sndio/blob/3f8bdefa5b4a63915ddd8335f01308756e021a4d/libsndio/sio_alsa.c#L32
I also attached my readelf and ldd output when querying
/usr/lib/libsndio.so.7.2, on the Manjaro unstable branch. You can see it
depends on libasound.so.2, which is part of alsa-lib package.

If you are running on other systems, it's also possible that the system
distributed libsndio.so is built using other backends, maybe OSS?

Actually, the different output from your machine and mine shows a perfect
example to support my previous scenario description, that why a game
developer should not depend on OS provided libraries.

Thanks,
Fuzhou
