10 months ago No change in output when running opam install -y dune utop num menhir user-setup ocamlformat ocamlformat-rpc ocaml-lsp-server after brew remove gcc.

10 months ago I think the instructions are outdated. The ocamlformat-rpc and user-setup packages are redundant for you, so you shouldn't install those. Also, num is long since deprecated in favour of zarith.
Also, before you install anything, make sure your copy of opam-repository is fresh:
opam updateThat said, the install worked for me in a new 5.1.0 switch with this command:
opam install dune utop num menhir ocamlformat ocaml-lsp-serverIgnore the warning about needing package user-setup, you don't need that since you're going to use ocamlformat, not ocp-indent.

10 months ago One piece of advice: for long extracts, use the <details> tag to let readers expand/collapse it as they prefer. GitHub makes it really easy to use with a slash command. Just press / on an empty line and the menu will pop up.

10 months ago Unfortunately, running opam update and opam install dune utop num menhir ocamlformat ocaml-lsp-server still causes the same linker errors during compilation. Thanks for the tip on long extracts.

10 months ago What does which gcc cc ar ld tell you? My gut feeling from a quick duckduckgoing is that ar is the faulty tool somehow installed through some previously installed homebrew package and it’s not mixing well with the rest of the usual Apple tools (i’ve seen that happened plenty of time in the past, though the error message is different this time around)

10 months ago It says:
➜ which gcc cc ar ld
/usr/bin/gcc
/usr/bin/cc
/opt/homebrew/opt/binutils/bin/ar
/usr/bin/ldI think you may be right. ar is a part of the binutils homebrew package. What's the best way to proceed?
Edit: I did brew uninstall binutils and now a significantly higher number of packages are installing and building.
New which:
➜ which gcc cc ar ld
/usr/bin/gcc
/usr/bin/cc
/usr/bin/ar

└─I’m guessing cmdliner previously built in a faulty state so opam reinstall cmdliner should fix that. Or if not, try reinstalling the whole switch using opam switch reinstall

10 months ago Everything appears to be working now. Thank you so much for your help! I would have never thought of a random homebrew package being the issue xD.

10 months ago This happens so often, I still think we should have this
that’s fair. I’ve opened https://github.com/ocaml/opam/issues/5784 to have it documented somewhere at the very least

I am following a fairly straightforward tutorial for setting up an OCaml development environment for a university course which has me doing the following steps:
OCaml is well-supported in macOS, so the installation process is fairly straightforward.
brew install make m4 gcc pkg-config fswatchopampackage manager for installing and maintaining different OCaml libraries. Execute the following lines from the terminal:~/.bashrc,~/.zshrc, and/or~/.profilefiles (if they exist, otherwise create the file as appropriate for your shell, e.g.,~/.bashrc):eval $(opam env)
ocamlc --versionfrom the terminal. You should get the output5.1.0, which is the version of the OCaml compiler we have just installed.Except when I run the
opam install -y dune utop num menhir user-setup ocamlformat ocamlformat-rpc ocaml-lsp-servercommand I am greeted with the following terminal output:No one, including the course staff, can provide any meaningful suggestions about these linker errors during the build process. For reference, I am on an M2 Pro MacBook Pro on macOS 14.2.1. GCC stats below:
I have tried uninstalling and reinstalling Xcode command line tools, and redoing each one of the steps in the instructor tutorial but to no avail. I have OCaml version 5.1.0 installed. Any suggestion on the matter would be greatly appreciated.
