@trev - XCode doesn't seem to be needed for my private programming needs.
Next is for the Raspberry Pi 4 which should get here on Monday.
As to the instructions, a link that brings one to the specific page where the source files are would be simpler, but more maintenance in the future, I suppose.
Better would be to have FPC and source all bundled in the Laz distro ... but would be a versions headache perhaps... or have the Laz distro offer the user different options during install? Perhaps too complicated depending on dependencies...
