Looks like a bad install of lua and/or lua-mysql and not an issue with asterisk.
By: Sergik (igels) 2011-01-25 03:02:10.000-0600

if replace pbx_lua.c from asterisk 1.6.x and rebuild, then everything OK.

Try to distill the differences between the two pbx_lua.c's then:

diff -uw asterisk-1.8.2.2/pbx/pbx_lua.c asterisk-1.6.x/pbx/pbx_lua.c

What makes the difference?

And if you take the original and only this replacement?

Thats work! Thank's!

I'm not able to replicate this issue on Ubuntu 10.04.1 with the latest 1.8 or trunk.
By: Leif Madsen (lmadsen) 2011-02-07 14:22:48.000-0600

I'm closing this per seanbright's comments.

Ubuntu 10.04.1 LTS
Asterisk 1.8.2.3
Same problem, same way to fix it.
By: Sean Bright (seanbright) 2011-02-11 13:27:23.000-0600

Can you try to replicate the problem with the latest 1.8 from Subversion?

 $ svn co http://svn.digium.com/svn/asterisk/branches/1.8 asterisk-1.8
 $ cd asterisk-1.8

Then configure and build as usual  If it fails - upload your config.log file.  This will help to isolate what exactly is wrong with your environment.
By: Sergik (igels) 2011-02-11 15:41:56.000-0600

I have updated my system to Ubuntu 10.04.2 LTS
and download Asterisk SVN-branch-1.8-r3075367.
The problem has remained.

I have attached a patch that causes the necessary symbols to be properly exported.
