Building Sagemath without Conda

[Aatman Supkar]

I want to set up Sage for development, but I don't want to use Conda due to its system-wide installs. What all methods for building Sage currently exist?

Hi,

Why not looking first at:

https://github.com/sagemath/sage#instructions-to-build-from-source

?

PS: I don't think Conda is system-wide by default, I use it regularly without root privileges.

This documentation has more detailed instructions about building without conda.

https://doc.sagemath.org/html/en/installation/source-distro.html

What OS are you building Sage on?

The build form source guides are helpful to some extent (I have tried both at some point), but I also find it breaking something or the other everytime. Just to be sure, I tried it again, after following the readme to the best of my ability (I don't know how to set the config variables, although I did make a rather clean PATH this time).

I'll attach a config.log if you can help me find the exact problem.

I'm using a MacOS 15.7.5, and am currently using Homebrew. But I have also been trying to abandon Homebrew and shift to Nix, so builds using that would be much appreciated.

As you can imagine, there is no way to tell what exactly is going on
from your "it breaking something or the other".

We also need logs/install.log to see the actual errors.

Here you go. Should I be adding both config.log and install.log while facing compilation issues in general?
