Hope this helps, and quick reminder, this is Alpine Linux 3.15.0 x86_64,
gcc version 10.3.1 20211027 (Alpine 10.3.1_git20211027). I'm not
normally a Linux user and only installed Alpine for the first time a
week ago, so I feel kind of lost on this machine. Sorry I can't be more
informative or helpful.
