Re: Static lib and lua5.1.dll (crash on lua_close_())

Hi Kristoffer,

Yes this is a multi-threaded application, in reality there is only one
main thread and there should only be one instance of the lua runtime.
(shared dll)

I'm actually using luabind in a dll that will be loaded by my main
application. I've tried to set all of the compile settings so that the
luabind.lib matches the compile settings that I used to compile lua,
but so far all I get are crashes.

I can load lua dll modules without any problems so I think that using
luabind in a dll should work.

mark.
