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

[Patrick Gundlach]

Hello all,

I have just updated the tl2018 pretest. This bug is still present. I am not sure if the update process has not fixed this or this is still present upstream.

I have rsynced tlprest and then run in the tlpretest directory

tlmgr --repository $PWD update --all

Shouldn't this fix the luatex binary?


Patrick

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:
