Unable to compile on Arch with GCC and Clang

GCC

Running command:

meson setup build -Drequire-nvidia=true -Drequire-amd=false -Drequire-python-hwdata=true -Ddaemon=true -Dplugins=true --prefix=$(pwd)/inst -Dlibdir=lib

Then I do cd build, followed by ninja.

I might look into fixing this as it's not too bad, but do struggle to find any free time 👍
