As long as swi-prolog-nox still provides a useable Prolog system I'm
happy. I would go with Jonas in that case though and have yet another
basic package that just contains the shared object and possibly the main
executable and boot file (swipl.prc)
Just the shared object is enough to create runtimes when using
--stand-alone as this creates a file that starts with the swipl
executable. Adding the swipl executable to the base package allows to
start the state with some option and makes the state smaller (but not
much, `swipl` is really short). Adding the boot.prc file adds only 90Kb
and actually allows running Prolog. Without libraries, but you could
distribute the essentials with some application as .pl or .qlf files.
If we rethink from the start, my ideal is that "swi-prolog" creates a
pretty much complete installation, including xpce (gui, ide). Yes, there
are quit a few dependencies, but virtually every desktop installation
has most of these installed anyway.
Then we can have some hierarchy below that. Some parts are clear, but
the real dependencies between the various packages is largely unknown
and easily varies between versions. If you are interested I could come
up with some meaningful splits.
Bottom line should be just the real core (as above), which is enough to
run saved states. You than have two options for saved states relying
on foreign packages: include the package in the saved state or install
the package.
