Error building from source

[Utkarsh Sharma]

Hi! I'm new to open source and wanted to contribute to Sage, so I tried building Sage from source code. However, whenever I run make, it throws this error at me saying that it's unable to build singular-4.2.1p3 and I have no idea what's causing it. I'm using macOS 12.3.1 on my M1 MacBook. Also, when I run ./configure, it tells me that it could not find an equivalent system package for singular, but when I brew install singular it says I already have it. I even tried reinstalling it, but ./configure still tells me to install it.

It would be nice if I could get some help with this. Here's the error and the corresponding log files:

Never mind, I tried uninstalling the singular I had downloaded from homebrew and ran make again, and sage installed it as an spkg. Now Sage works fine on my computer.
