Hi, George,

Sorry to bother you. Though ghc seems to run properly, here's what ghci prints on my screen. What mistake did I make? Should I delete and reinstall the software you told me to install?

"GHCi, version 9.4.4: https://www.haskell.org/ghc/  :? for help

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

`gcc' failed in phase `gcc'. (Exit code: 1)

williammcenaney@Williams-Air bin"

Thanks.

Bill

Hi Bill

Yes,GHC will run on your new MacBook Air. The cpu in that is Apple Silicon , the aarch64-apple-darwin platform. Older Macs run on Intel chips, the x86_64-apple-darwin platform. 

I'm not sure how you installed the compiler. I believe the standard way is described on https://www.haskell.org/ghcup/. Can you tell us how you installed it?

Thanks 

George

Redirecting this query to ghc-devs.  Can anyone help William?  Thanks!

Will GHC run on my new MacBook Air? After installing the compiler, my laptop said its processor was wrong for the binary distribution I chose. If there is a dmg file for MacOS 12.5.1, please please link your reply to it.
