(On FreeBSD, you need to pass an extra flag to prevent a linking error: `meson build -D b_lundef=false`)
## Running the Reference Compositor
wlroots comes with a reference compositor called rootston that demonstrates the
features of the library.
After building, run rootston from a terminal or VT with:
./build/rootston/rootston
Now you can run windows in the compositor from the command line or by
configuring bindings in your
[`rootston.ini`](https://github.com/swaywm/wlroots/blob/master/rootston/rootston.ini.example)
