Re: Installing GHC on my MacBook Air

[George Colpitts]

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-d...@haskell.org
and  glasgow-haskell-users@haskell.org

Cheers
George

 Dear Dr. Jones,

 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.

 Thanks for your help.

 Best,
 Bill

Re: Installing GHC on my MacBook Air

[Steven Smith]

I recommend using macOS package managers to take care of all this. There’s a whole community of knowledgeable folks who have figured out all these build and install details, and I know that it’s simply a matter of doing this to get a working version of the latest, on either x86_64 or arm64 machines:sudo port install ghcThat’s using MacPorts. There are other options, but I strongly recommend MacPorts for several reasons, especially for development tools.On Mar 15, 2023, at 12:04, George Colpitts  wrote:Hi BillI'm cc'ing GHC dev and GHC users as someone else may have a better answer, catch a mistake I made etc. Please don't delete them.I believe you have encountered https://gitlab.haskell.org/ghc/ghc/-/issues/21506#note_447206I believe the way to fix this is to do the following:rm -fr /usr/local/bin/ghc*rm -fr /usr/local/lib/ghc*./configuresudo xattr -rc .sudo make installHowever I am unsure why you are encountering this as the issue is supposed to have been fixed.CheersGeorgeOn Wed, Mar 15, 2023 at 11:21 AM William McEnaney  wrote:Hi, George,I got this message when I ran make install with the sudo command.

I forget what I did to install it. But the compiler and other ghc-related programs live in /usr/local/bin. Since I installed the wrong binaries, I changed the directory to /usr/local/bin and tried to empty that directory with rm -rf ghc*.*, but that didn't delete anything. So I wonder whether I'll need to remove those programs before reinstalling ghc.Thanks for your help, too.Best,BillOn Wed, Mar 15, 2023 at 7:59 AM George Colpitts  wrote:Hi BillYes,GHC will run on your new MacBook Air.
