Linking Lua with Visual Studio 2010 - c++

Question

We use Lua (www.lua.org) script to let users to customize our server software written in C++.
At the moment we are porting the 32 bits Windows version of our project to Visual Studio 2010.
Once everything works fine with VS 2008, we thought that we would have no problem on upgrade process.
Unfortunately whenever we tried to link the lualib (as dll) to our project in VS 2010, the lua functions could not be found by the linker (the error messages are displayed below).
It seems that some calling convention is wrong on 2010, like the application may be looking for the lua functions with a prefix '_'.
To access lua functions (written in C) from our project modules (C++) we use this:
extern "C" {
#include "lua/src/lua.h"
#include "lua/src/lualib.h"
#include "lua/src/lauxlib.h"
}
The same project compiles and links with lualib successfully on VS 2008 and Linux (g++).
Could anybody help me with this ?

The reported missing names are correct, this not a compile problem. You must be linking the wrong .lib. The name you use sounds wrong, it isn't "lualib", the current version of the import library is named lua5.1.lib (or lua51.lib, not sure what the difference is). Download it from here.
