Please provide a self contained example that reproduces this, as it builds fine when I try it.

The build times are normal in my nix-ros-overlay builds that use the pinned nixpkgs version, but I'm observing the long build times with one of my NixOS machines that uses...

If I had to guess: https://github.com/NixOS/nixpkgs/pull/287957

Sorry for not getting to this sooner. This should be fixed in nixpkgs; `libspnav` needs to propagate `libX11`.

I just wrote a quick and dirty I2C master driver using USI: https://github.com/lopsided98/acurite-thermometer/blob/main/acurite-thermometer/src/i2c.rs. It is pretty closely based on AVR310, but is missing any and all delays because I only...

If you are just doing development or running ROS processes manually, you don't put anything in your NixOS config. The NixOS modules are only needed if you want to start...

It needs a rosdep key for `libmongoclient-dev`.
