Install on Mac M2 - Githubissues

spike7638 commented 4 hours ago

I'm having trouble installing ocaml on my Mac M2.

Like https://github.com/ocaml/opam/issues/5783, I'm trying to install ocaml on a new Mac; It's an M2, and I'm using Sonoma 14.7.

Copying the approach taken there, I've done the following

Installed XCode
Installed homebrew; edited the .zprofile to include homebrew in my path
brew install make m4 gcc pkg-config fswatch
added m4 to my path with echo 'export PATH="/opt/homebrew/opt/m4/bin:$PATH"' >> ~/.zshrc
brew install opam ; resulted in error saying I hadn't agreed to the Xcode license; ran sudo xcodebuild -license accept to address that and tried again. It worked the second time.
opam init; that worked, and told me that zsh completions had been added to various things.
Followed advice on setting a particular switch and ran eval $(opam env --switch=5.1.0 --set-switch)
Following advice from that other issue: brew remove gcc; that worked too.
opam update. (resulted in 'no changes')
Following yawaramin's advice, did opam install dune utop num menhir ocamlformat ocaml-lsp-server, but in retrospect this seems inconsistent with the advice that "num" is superseded by "zarith". Either way, this is where things went wonky -- several packages failed to install:

this is not an issue with opam (the tool) but with the packages (opam-repository) so i've moved your ticket where it's more appropriate.

Now for your issue, my guess is that brew remove gcc somehow removed zstd. Could you try to do: brew reinstall zstd

If that doesn't work you could ask people in https://github.com/ocaml/ocaml/issues/12562 to see if someone has a better idea

That seems to have worked; thanks. So the summary of a now-working sequence of installs seems to be

Install XCode
Run sudo xcodebuild -license accept
Install homebrew; edit the .zprofile as advised at end of install to include homebrew in path
brew install make m4 zstd pkg-config fswatch
add m4 to path with echo 'export PATH="/opt/homebrew/opt/m4/bin:$PATH"' >> ~/.zshrc
brew install opam
opam init
Followed advice from the "init" on setting a particular switch by running eval $(opam env --switch=5.1.0 --set-switch)
opam update. (May result in 'no changes')
opam install dune utop num menhir ocamlformat ocaml-lsp-server
opam user-setup install

Sadly, this didn't seem to make my project using reprocessing work -- I still get an assembler error! -- but that's a different problem.
