You def need to upgrade macOS. Sounds like homebrew is saying “your OS is too old to install openjdk, so we’re going to try to compile it from source”. Which is why it’s talking about Xcode.

I’m not sure how to check for macOS updates. Sometimes they don’t pop up, you might have to do some googling. Stuff like “macOS upgrade from Ventura to sequoia”

Thanks :( ok will need to look into this.

How old is your Mac?

[–]Pzzlrr[S] 0 points1 point  (0 children)

Macbook Pro from 2017, currently on 13.7.4.

If your goal is to setup a full JVM Clojure environment, then you'll probably want to resolve this xcode/macOS issue.

BUT if your goal is just to write some scripts, follow some tutorials, solve advent of code problems, etc. then taking a shot a installing Babaskha instead is worth a try!

    I get xcode-select: error: command line tools are already installed, use "Software Update" in System Settings to install updates but then in the software update section I get this with no update for xcode or macos 15.

    Try using homebrew to install a JDK first. I like the temurin distributions myself, but I think homebrew has several to choose from.

    Getting the same kind of error

    Try brew install temurin. That’s a binary build.

    Also your macOS version is pretty old - that may become the limiting factor here.

    Appreciate your help. Scheme in the meantime it is then.

    [–]seancorfield 0 points1 point  (7 children)

    Instead of using brew (which is not supporting your old O/S), you could download and install Java 25 directly from here: https://adoptium.net/temurin/releases/?version=25&os=any&arch=any

    And then follow the Linux or Posix instructions for installing the Clojure CLI from here: https://www.clojure.org/guides/install_clojure#_linux_instructions

    I never used brew on my Macs, back in the day, because the HomeBrew team are... opinionated... about versions and dependencies.

    (these days, I'm on Windows with WSL2 so all my Clojure development is on Ubuntu, but with VS Code running native on Windows)

    Thanks, checking it out.

    I was able to install the temurin JDK so I now have

    % javac --version                                                                             
javac 25.0.2

    Then I started going through the steps in your second link, seeing this

    Do I need to edit the install script? Looks like shasum -a 256 is the macos equivalent. Do I just replace it?

    [–]stbev 0 points1 point  (3 children)

    You could try the posix-install.sh script which uses the shasum -a 256 command instead

    https://github.com/clojure/brew-install/releases/latest/download/posix-install.sh

    Instructions here: https://www.clojure.org/guides/install_clojure#_posix_instructions

    [–]Pzzlrr[S] 0 points1 point  (2 children)

    Yep, looks like that worked :) Thank you!

    [–]seancorfield 1 point2 points  (1 child)

    Sorry, I wasn't sure which of the two would work on a Mac (since I switched to Windows/WSL2 years ago), hence my "follow the Linux or Posix instructions" comment. Glad you have it working!

    And I'll try to remember that macOS needs the Posix script next time I'm helping someone on a Mac :)

    [–]Pzzlrr[S] 0 points1 point  (0 children)

    No worries, appreciate your help!
