You'll need to downgrade your ARM GCC version - 9.1.0 apparently has some problems. I believe 8.3.1 is good.

Thanks. Had the same issue with my DZ65, downgrading to 8.3.0-1 worked for me.

Awesome, glad to hear it.

Does this mean that there are no future plans to support 9.1.0, or by proxy, vanilla installs of Arch Linux?Curiosity more than anything; I don't mind using Docker to build & load.

I also ran into this and it seems like a temporary fix is to add the environment variable ALLOW_WARNINGS=yes
