Re: Installing GHC on my MacBook Air

Type the following at the command line: xcode-select --install and then try ghci again. I'm not sure what you mean by "the software" in the phrase "Should I delete and reinstall the software you told me to install?" but in any case don't delete anything. Please try to be as specific as possible. When you first encounter a problem you should Google for a solution. If that doesn't work you can send mail to me but also cc ghc-devs@haskell.org and glasgow-haskell-users@haskell.org Cheers George On Thu, Mar 16, 2023 at 11:09 PM William McEnaney < bill.mcenaney.jr@gmail.com> wrote:

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

Thanks.

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
