Re: Trouble running the hello world application

that is typeinfo for luabind::detail::registration which i'd bet is in the
luabind library.

if you look at your link command below you will see you are not linking the
luabind itself, hence the undefined symbol

add a -lluabind and all should be well.  you may need also to add a
-L<where ever the lib is path> so the linker can find it.

-tom

ps - you don't need to add the .so when requiring the file, and you might
drop the 'lib' prefix of the library to make it look more natural in lua.
then you could just right

require('hellobind')

Got visibility?
Most devs has no idea what their production app looks like.
Find out how fast your code is with AppDynamics Lite.
