G'day,
As promised, I obtained a copy of SLES12 (Service Pack 5), and
installed it in a virtual machine.
SLES12SP5 provides:
Lua 5.2.4 Copyright (C) 1994-2015 Lua.org, PUC-Rio
Sadly, my "lglicua" Assistant currently demands that Lua 5.1
(5.1.5) be installed as the "current" OS-provided Lua version;
see:
- install/support/family-ubuntu.sh, function
LuaSelect, where we take advantage of Ubuntu
offering an "update-alternatives" command;
- there is no equivalent in Red Hat/CentOS-7, as 5.1 is
"baked in"; and
- Gentoo provides "eselect" as a selection tool for
many items, including "lua", e.g.
- eselect lua list
- eselect lua set lua5.1
- eselect lua set lua5.4
These switching commands usually work by a pair of symlinks,
one to make the each of the possible variants available at a
dynamic place in the filesystem (instead of, say, /usr/bin/),
and a second symlink, manipulated by the selection mechanism,
that links from somewhere on the shell PATH into the dynamic
area.
Under Ubuntu (and its derivative, GNU/LinuxMint), there are
individual items to select "interpreter" or "compiler". The
Assistant always treats them as a pair (with a ?? REVIEWME
marker noting that the script may not be correct if the
interpreter switch succeeds, but the compiler switch fails).
-----
So, sadly, the gap between the capabilities of the Assistant
and what SLES12SP5 provides is too big for me to tackle at
present.
SUSE/SLES being a commercial product, requiring registration,
and only offering a limited-time free trial, also discouraged
me from exploring to any great depth.
