Problem building poky

Hi
I am completely new to linux and so will make rookie mistakes. Apologies
for that.
I have set up my pc as a dual boot and am running ubunutu 24.04.3.

Due to limited hard disk size I have connected an external drive which has
been formatted as ext4 and have installed poky on it.

I have followed the Quick Build instructions for poky on scarthgap branch
using bitbake core-image-sato to build

After a while it errors. Here are the last few lines of the log. There are
quite a few undefined references reported.

collect2: error: ld returned 1 exit status

I would have expected this to build without any errors as I have not
modified anything. Part way through the build my session became
unresponsive (mouse not moving - I was using it to keep the terminal alive)
and the terminal stopped and returned me to the desktop.

Could somebody advise on how this can be resolved.

Kind regards
