FWIW I think you'll have a very hard time compiling anything until the new native code gen backend is released (GHC 9.2.1 IIRC)

Hey guys, just wondering if I could get a little help with using Haskell for the first time, I want to use an MQTT library just to see how Haskell works a bit:

user: matthew ~/tmp/haskell took 6m27s 
❯ nix-shell -p 'ghc.withPackages (ps: [ ps.net-mqtt ])'

user: matthew ~/tmp/haskell via ❄️  impure (shell) 
❯ cat mqtt.hs 
import Network.MQTT.Client

main :: IO ()
main = do
  let (Just uri) = parseURI "mqtt://test.mosquitto.org"
  mc <- connectURI mqttConfig{} uri
  publish mc "tmp/topic" "hello!" False

user: matthew ~/tmp/haskell via ❄️  impure (shell) 
❯ ghc mqtt.hs
[1 of 1] Compiling Main             ( mqtt.hs, mqtt.o )

mqtt.hs:6:20: error: Empty record update
