Enable LIRC support in the kernel
Currently (2018-07-23) the NixOS kernel is not compiled with LIRC support, therefore no /dev/lirc0 will appear when you add an IR receiver.
To enable LIRC support for NixOS you will need to recompile your kernel with CONFIG_LIRC=y.
With NixOS the boot.kernelPatches option can be used:
{ lib, ... }:
{
boot.kernelPatches = lib.singleton {
name = "enable-lirc";
patch = null;
extraConfig = ''
LIRC y
'';
};
}
LIRC Service
As of right now, no lirc service is provided by NixOS, You can start the LIRC Daemon manually like this:
$ lircd --listen -n -P /var/run/lircd.pid -o /var/run/lirc.sock -d /dev/lirc0
You can build upon this to create your own service with sytemd.services.
