Unable to build sage from source on M4 Macbook

[Pavel Galashin]

Hi all,

I am trying to build a local sage version for development and keep running into the below problem. 

I have been following this manual and the README file. In particular, all the homebrew packages have been installed, and I also did the

source ./.homebrew-build-env

I am on an M4 Macbook Pro (2024), Mac OS Sequoia 15.2.

Not sure if this is relevant: I recently migrated from an intel 2020 macbook, and migrated homebrew as described here.

Any help would be appreciated!

Why won't you use Python from Homebrew?
Not that it explains your error, but they know how to build Python on macOS.

[Dima Pasechnik]

You can install Homebrew's Python 3.12 :

    brew install pyt...@3.12

and run

    ./configure --with-python=python3.12

to tell Sage to use it and do not build Python.

Thank you! Python was already installed by Homebrew but somehow not attached to the command ``python``, only to ``python3``. I symlinked one to the other and made progress (still getting another error but much later in the process and unrelated to python - will post in a different thread).
