I updated the Getting Started with C++ tutorial earlier this week so the build instructions in there should be current - they worked OK for me on a Pi, anyway.
There have been significant changes to the Picosystem libraries over the last month or so, so if it’s not playing it might be worth starting from scratch with a new Pi OS image in case you’ve got an old or broken version of the Pico SDK or the Picosystem SDK lurking somewhere and causing problems? At the very least, it’s worth getting rid of any directories you’ve tried to build into unsuccessfully as these can cause cmake to fail in mysterious ways.
The folks on the 32blit discord might be able to to help if you’re struggling with the C++ buildchain, they are cmake ninjas :)
Thanks, I have not tried again since Monday. I’ll try the install ASAP and let you know how it goes.

I created a new Pi OS SD card and booted from it and the “Getting Started with C++ tutorial” worked I am using Twister OS for my Pi and have a really nice setup with lots of tools and utilities.
So then I tried a fresh Twister OS SD card boot to make sure there wasn’t something wrong with my OS, and the “Getting Started with C++ tutorial” failed so it doesn’t like something about Twister OS the weird thing is an older version of your SDK that I used at first worked just fine until you updated the SDK and now it doesn’t.
Is it possible to take a look at this to see what might be happening - why the SDK isn’t working with Twister OS.
Thanks,
Brian

Glad to hear that it worked OK with Pi OS, phew :)
I’ve not had anything to do with Twister OS I’m afraid - what build errors are you getting? Can you build the Pico SDK examples? (Instructions on how to do that are from page 6 onwards of the Pico Getting Started ). Might be worth trying sudo apt install ing the extra toolchain packages mentioned on page 7, in case they’re not included by default?
Does this mean anything to you, this is what I get when I try to compile the examples:

I’m getting the same thing on Twister OS - possibly some mismatch between compiler/c/pico-sdk versions going on?
It might be related to recent pico-sdk changes - this sounds like your error, if you wanted to keep an eye on it? Compiling Error: duplicate 'inline' · Issue #659 · raspberrypi/pico-sdk · GitHub
I’ll update the getting started to make it clearer that Raspberry Pi OS is the distro we recommend for dev purposes.
Thanks for trying, Man, I hope this gets fixed, Twister OS is so much better than the Vanilla Pi OS. It has way better window docking built in (like windows 10)
