hi everyone! i am having a lot of trouble figuring out Haskell and ghc again, i would like to uninstall everything and start from scratch, it's confusing for me the difference between Haskell/ghc/cabal/haskell. Right now my VScode crashes like this: Warning: GHCi | Loaded package environment from /Users/montoyamoraga/.ghc/x86\_64-darwin-8.6.5/environments/default Prelude\> Prelude\> Warning: GHCi | Warning: GHCi | : error: Warning: GHCi | Ambiguous module name ‘Sound.Tidal.Context’: Warning: GHCi | it was found in multiple packages: Warning: GHCi | tidal-1.4.7 tidal-1.4.7 tidal-1.4.7 tidal-1.4.7 tidal-1.4.7 Warning: GHCi | Warning: GHCi | :6:39: error: Not in scope: ‘oLatency’ Warning: GHCi | Warning: GHCi | :6:55: error: Not in scope: ‘oAddress’ Warning: GHCi | Warning: GHCi | :6:79: error: Not in scope: ‘oPort’ And my SuperCollider like this: \*\*\* ERROR: dlopen '/Users/montoyamoraga/Library/Application Support/SuperCollider/Extensions/SC3plugins/StkInst.scx' err 'dlopen(/Users/montoyamoraga/Library/Application Support/SuperCollider/Extensions/SC3plugins/StkInst.scx, 2): no suitable image found.

Hi @montoyamoraga, This is an annoying and by now longstanding bug in Haskell… You can fix it by deleting `/Users/montoyamoraga/.ghc/x86_64-darwin-8.6.5/environments/default` (the file mentioned at the top of the message as the ‘package environment’), and running `cabal install tidal --lib` again. ---

thank you @yaxu! that made the trick, now it's working 🙂 ---

Hi @ana.mora, This tends to fix this problem: ```bash xcode-select --install ``` Possibly you might also need this: ```bash xcode-select --reset ``` Hope that helps, let me know how it goes! ---

Thank you for your help. I think it was working pretty well. No error messages until I opened Atom. I boot tidalCycles and the window below was fine I guess: Ghc-pkg command: /Users/alfonsinamora/.ghcup/bin/ghc-pkg Load BootTidal.hs from /Users/alfonsinamora/.atom/packages/tidalcycles/lib/BootTidal.hs Loaded package environment from /Users/alfonsinamora/.ghc/x86\_64-darwin-8.6.5/environments/default t\> t\>Listening for controls on 127.0.0.1:6010 t\> Then when I tried to run the line d1 $ sound “bd sn” something went wrong. Failed to send. Is the ‘SuperDirt’ target running? Network.Socket.sendBuf: does not exist (Connection refused) Thank you once again and sorry for all the inconveniences. ---

Hi @ana.mora - what happens when you run SuperDirt.start in SuperCollider? ---

Thanks a lot! There was a file of SC in a wrong location, I put it in the right place. Now everything works !! Thanks @yaxu and @heavy.lifting for your help !!! Looking forward to start 🙂
