Partial Builds
--------------
You can choose the core components to build via --enable-* or --disable-*
configure option for reducing the size of libasound. The selectable
components are: pcm, mixer, rawmidi, hwdep, seq and instr.
For example, --disable-rawmidi will prevent to build the stuff related
with raw MIDI. As default, all components are enabled.
The PCM plugins to build can be selected via --with-pcm-plugins
configure option. Multiple plugins can be passed by separation with
comma. For example, to select _only_ rate and linear plugins (and
disable other plugins), pass
--with-pcm-plugins=rate,linear
Note that "hw" plugin is always enabled.
Passing "all" will select all available plugins (which is the default
behavior).
When you select "plug" plugin, copy and linear plugins will be
automatically selected, too. That is, the linear-format and
access-type conversions are always available with plug layer.
The other conversions of plug (channel shrink/expansion, rate,
non-linear and float conversions) are enabled when the corresponding
plugin is selected, too.
