Unable to Build

[johncharris]

I just installed Platform IO on my Windows 11 system to run this. When I compile, I get the following errors. I'm not very proficient in C++ so I have no idea what's going on. How can I get this to compile?

Hi, I will have a look later. Which directory did you try to compile ?
