@Thaddy, I am not a Lazarus Guru. I followed the steps in the book I bought.
So you are now also seeing the issue I have. The IDE is broken and you are not able to add a new event by double-clicking on the components.
I just want the IDE to work on the Pi 4. I want to make sure the system we build is future proof and at this stage I am stuck.
Who from the Lazarus team looks after this. Rik you stated I can add it to a mailing list somewhere but not sure where or should I leave it with you 2 to sort out ?
There is not much I can do, but I reported the bug (it is a serious one) on the bugtracker. The mailing list you want is fpc-devel.
For now, if you install FPC 3.0.4 and Lazarus 1.8.4 from apt, so not the newer versions, you can still work with Lazarus on the Raspberry Pi 1/2/3/4
First remove your FPC and Lazarus.
sudo rm -rf /usr/bin/fpc
sudo rm -rf /usr/local/bin/fpc
sudo rm -rf /usrlocal/lib/fpc
Same for Lazarus.
adapt your sources.list like mine.
sudo apt update && sudo apt dist-upgrade -y
sudo apt install fpc
sudo apt install lazarus
sudo apt autoremove
check the /etc/fpc.cfg file if all paths are correct.
