This might be a bit of a newbie question. I can see from the following URL that Kevin Mihelich has been updating GCC to the latest versions. At the time of writing, this was version 9.2.0-3 (24 hours ago).
https://archlinuxarm.org/packages/armv7h/gcc/log
However, after updating the files database and searching it with pacman, I get the following on my board (an ODROID-XU4).
$this->bbcode_second_pass_code('', '[root@alarm ~]# pacman -F gcc
core/gcc 8.3.0-1 (base-devel) [installed]
usr/bin/gcc
extra/bash-completion 2.9-1
usr/share/bash-completion/completions/gcc
community/ccache 3.7.4-1
usr/lib/ccache/bin/gcc
community/colorgcc 1.4.5-1
usr/lib/colorgcc/bin/gcc
community/distcc 3.3.3-1
usr/lib/distcc/bin/gcc
usr/lib/distcc/gcc')
Why is pacman configured to use the GCC version from 6 months ago?
