Bug#665279: pointing luatex to external lua modules
Package: luatex
Version: 0.70.1-1+b1
Severity: wishlist
Hi,
This should possibly be filed against texlive-luatex. Please redirect
as appropriate.
When using luatex on Debian, it does not automatically find lua
modules that are installed on the system as part of a regular lua
installation. Since (I believe) it is possible for luatex to use these
modules if it sees them, it would be nice if either this worked out of
the box, or configuration instructions were provided to Debian luatex
users.
This issue came up in the context of the following tex.sx question -
http://tex.stackexchange.com/questions/48193/reading-data-from-a-relational-database-into-a-latex-table
When I attempted to import Lua bindings for sqlite, apparently in
liblua5.1-sql-sqlite3-2, the luatex interpreter was unable to find
them.
I'm using the TeX Live 2012 beta from experimental - see version
information below. TeX Live 2009 in stable clearly would not suffice
for Patrick's example in http://tex.stackexchange.com/a/48233/3406 as
it doesn't contain luacode.sty.
I tried the simple and obvious of approach of copying what seems to be
the correct .so files into the current directory, but that didn't work
either. These may have been the wrong files; I copied
liblua5.1-sql-sqlite3.so.2.0.0 from the liblua5.1-sql-sqlite3-2
package. The other two .so files in that package are symbolic links of
that one, so I made put three copies of the same file in there with
their different names, in case it made a difference. But it didn't.

In the comments of
http://tex.stackexchange.com/questions/14361/installing-lua-modules-for-use-in-lualatex
someone suggested setting the CLUAINPUTS path. Is this a viable
approach? I don't know where or what to set it to, though.
This bug - http://bugs.debian.org/441595 looks vaguely related.
I might ask the Luatex people about this as well.
