Hello,
I am using Manjaro Gnome 21.10 and am fairly new to arch-Linux since I am used to Debian. This is a bit of a learning curve for me , so I appreciate any help I can get.
I am following these instructions
https://github.com/Gadgetoid/pi400kb
from git hub to use my rpi400 as a keyboard for my pc (Since both my mini Pc and Rpi400 are sharing the same screen, so I would like to use the one keyboard to control them both; Hence the rpi400. --I know the rpi400 is a computer but I need the mini Pc to run apps that the RPi can’t like Steam and Sketchup (No, I don’t want to use VNC or SSH), So I just switch between them. )
Anyways, I got the files downloaded but I can’t get cmake to work. I just get the error:
bash: cmake: command not found
I tried downloading cmake from the Manjaro software store (The add/ remove software app) but it was corrupted and never installed. I also tried,
sudo pacman -S cmake
and it stated installing:
Packages (4) jsoncpp-1.9.4-1 libuv-1.42.0-1 rhash-1.4.2-1 cmake-3.21.3-1
The I got a couple corruption errors like this:
error: jsoncpp: signature from "Arch Linux ARM Build System <builder@archlinuxarm.org>" is unknown trust
:: File /var/cache/pacman/pkg/jsoncpp-1.9.4-1-aarch64.pkg.tar.xz is corrupted (invalid or corrupted package (PGP signature)).
and I deleted the files, so basically nothing was installed.
Does anyone know how I can get this github keyboard program to install and work?
Thanks in advance.
Here’s a screenshot of what I did for installing the GitHub files can be found here on the rpi forums page (Since it won’t let me upload the screenshot): `
