I just poked around looking how that all works; there's a pretty limited
set of libraries available for cross compiling it seems.

You could dig around in the debian repository and find the right
package, extract the files and use them for the build? Or just not worry
about it and plan on using mu-editor to write programs.

Thanks; I've browsed a bit, looks like good progress

The EV3 sensors and actuators are way more sophisticated than what we've
used on other devices, so I'm not sure if it makes sense, but I'd love
to see the API look more like how Snek works on other boards, which uses
the LEGO Logo semantics:


If you can take a look at the Snek manual and see how those are defined,
it would be awesome to make this port look as much like that as we can.
