Error installing scipy when building Sage 10.1 from source under WSL2:

[Jeremy Martin]

I am trying to build Sage 10.1 from source under WSL2 running Ubuntu 22.04.3 (jammy).  I have followed the directions at https://doc.sagemath.org/html/en/installation/source.html# and https://github.com/sagemath/sage/#instructions-to-build-from-source.  The make fails with "Error installing package scipy-1.10.1".  I am attaching the logfiles as requested.

Disclaimer: I am far from an expert with package managers and the like, so I am hoping for a simple fix!  By the way, I tried

$ sudo apt install scipy

and

$ sudo apt install scipy-1.10.1

but neither of these things succeed ("Unable to locate package").

Thanks for your help,

Jeremy

I see

g++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

in your scipy log.

This most probably means that you ran out of RAM. You'll need to
allocate more RAM to your WSL2.

typically Python package names on Ubuntu/Debian are prefixed with
python-, or python3-.

Anyway, while 10.1 is not able to use system-wide scipy, our recent
10.2.betas can do it.
(you'll need to run ./configure --enable-system-site-packages)

Thanks, Dima!  Increasing WSL's memory allocation to 6GB from 4GB fixed
the problem and the rest of the compilation went off without a hitch.
