May be changes upstream that has broken compilation – you can post a logfile from the logs directory to a site like pastebin and I can look more (Or open a ticket on github and I’ll check when I next have a moment)
Looks like you may have run out of memory when compiling. You may need to lower gpu allocated ram via /boot/config.txt and try again – I’ll check on my 256MB pi and perhaps add some virtual memory for this module.
Thanks Buzz. I lowered the GPU allocation to 16MB and attempted the build again, but it didn’t work.
A while back I disabled and uninstalled the swap feature from my RetroPie build (to reduce chance of corruption due to power loss) so I will have to look about reinstalling that, or making new temporary swap file and attempt the build again.
