[tex-live] TL2018/LuaTeX/Mac "bug" (but also probably in all other distributions as well)

Hello again,

in tl2018 (pretest) we have the same bug as last year. Would it be possible to fix it once and for all? (or should I setup a cron job?)

$ type lualatex
lualatex is hashed (/opt/texlive2018/bin/x86_64-darwin/lualatex)
~/TeX/luatex/test$ lualatex test
This is LuaTeX, Version 1.07.0 (TeX Live 2018) 
 restricted system commands enabled.
LaTeX2e <2017-04-15>

(/opt/texlive2018/texmf-dist/tex/latex/booktabs/booktabs.sty) (./test.aux)error
 loading module 'luasql.sqlite3' from file './luasql/sqlite3.so':
	dlopen(./luasql/sqlite3.so, 6): Symbol not found: _luaL_argerror
  Referenced from: ./luasql/sqlite3.so
  Expected in: flat namespace

where test.tex is:


luasql = require("luasql.sqlite3")

env = assert (luasql.sqlite3())
-- connect to data source
con = assert (env:connect("luasql-test"))
-- retrieve a cursor
cur = assert (con:execute"SELECT name, email from people")
-- print all rows, the rows will be indexed by field names
row = cur:fetch ({}, "a")
tex.sprint([[Name & email \\\midrule]])
while row do
  tex.sprint(-2, row.email)
  -- reusing the table of results
  row = cur:fetch (row, "a")
-- close everything

and sqlite3.so is from homebrew (put online at https://download.speedata.de/private/sqlite3.so)


> Hi all,

> When building LuaTeX without --nostrip (which is the current default behaviour), loading external libraries is a game of luck. For example the sqlite3 bindings from http://luaforge.net/projects/luasqlite/ [^] create a library on OS X that require the symbol _luaL_argerror to be defined in the LuaTeX binary:

> Building LuaTeX with --nostrip solves this issue.
> By having "--strip" the default in build.sh, it is not possible for any user (on OS X, perhaps also on other platforms) to use this (and other) external library without downloading the LuaTeX source, download XCode, compile LuaTeX and put LuaTeX in the correct place.
