If you have the code from the first edition, downloaded before the update, then you should be aware that it will not work on the Pi4 or Pi5. And quite probably not on Pi3 even with older Rasbpian OS.
Too many updates to other things have totally depricated the code. I can't get it to build on several of my older Pi3's either.. I have now removed this old content from the Website, I just can't support it any more.
Of course this is an issue, you can't download or even enter the code snippets from the original edition and I was very upset that people contacted me with news that their code no longer worked.
But... there's now a solution.
The new version of Raspberry OS, Bookworm, will allow us to get a new dualboot version of the download code up and running on a Pi3. the code layout will be a little different but the main code intentions (and some of the deliberate errors) will still be usable.
I am actively working on updating all the Pi3 code and adding it to the Downloadable content, it should all be in place before the summer holidays.
As far as the 1st edition printed code is concerned, consider it depricated, you will find the new download code has much of the same content but order is changed and some filenames altered, as well as the bits that no longer work (mainly DispmanX and BCM utils) have been removed and replaced with more generic X11/EGL content.
I am producing some website content to explain the changes.
