[Nix-dev] Building ghcjs-dom

[Ryan Trinkle]

Hi Rodney,

You could take a look at
https://github.com/reflex-frp/reflex-platform/blob/develop/default.nix .  I
didn't realize upstream wasn't building, but I always keep reflex-platform
building (and with binary caches available, see
https://github.com/reflex-frp/reflex-platform/blob/develop/notes/NixOS.md
).  If there's anything in there that can be reused upstream, please feel
free to take the code you need, and I'll help move things upstream however
I can.


Best,
Ryan
