How to do a Lua<->C hello world in Lua 5.1?

[Steve Litt <slitt@...>]

Hi all, 

I've been RTFW all night but no joy when it comes to either running C from Lua 
or running Lua from C. I tried this:

http://heavycoder.com/tutorials/lua_embed.php

but kept getting "embed.c:23: error: invalid storage class for function 
openlualibs"

It seems like my computer has /usr/lib/liblualib50.so.5 but no corresponding 
liblualib51.*, and I'm using Lua version 5.1.4. My Ubuntu is 9.10. If I knew 
the old version was the problem I'd upgrade, but I'd hate to go through all 
that mess on anything but a very educated guess.

Is there anywhere on the web that has an up todate, for Lua5.1, bare bones 
absolutely minimal example of Lua interfacing with C?

Thanks
