Unable to compile on ArchLinux

Hey, I wanted to try your project you wrote about on dev.to but I'm unfortunately unable to compile link on ArchLinux:

Hi, I will try to get some time to make the compilation work and find the exact version I used back then. Sorry, should have made the installation guide more detailed :( I have a lot of work right now, I’ll comment back here once I manage to do it
