[gentoo-user] Problems lua/luarocks

[meino.cramer]

Hi,

I got some problems with lua and its package manager called
"luarocks". From the lua mailing list I got the information,
that luarocks normall installs lua module/packages/"rocks" 
below /usr/local ... a place lua will look for, when adviced
to use a certain module.

With Gentoo, luarocks was fixed to install below
/usr/lib64/lua/luarocks/lib/luarocks/rocks
but lua wasn't instructed to do the same.

Regardless what "rocks" I am installing, lua won't find
it. So what can I do to fix that?

Thank you very much for any help in advance!
Best regards,
mcc

I built a simple module, called by a likewise simple program.
after some searching around I found that by setting LUA_PATH with

export LUA_PATH=/usr/lib64/lua/luarocks/share/lua/5.1/?.lua;

I succeeded in running program + module.

I don't know, though, wether this works in more complicated
projects, but you might give it a try. If it works, you should
set LUA_CPATH too (if you want to include C-modules).
