I have Lua 5.1 and Luabind 0.7. I am taking the approach of including the Luabind header files in my project instead of building them as a library/DLL, mainly because I cannot for the love of everything holy figure out exactly how to use Boost-Build to actually build Luabind into something usable.
Anyways, I am using the following code for my application:
/*
Main.cpp
*/
extern "C"
{
#include <lua.h>
#include <lualib.h>
#include <lauxlib.h>
}
#include <iostream>
#include <luabind/config.hpp>
#include <luabind/class.hpp>
#include <luabind/function.hpp>
#include <luabind/open.hpp>
void greet()
{
std::cout << "Hello World!\n";
}
void main()
{
// Initialize Lua and load default libraries.
lua_State* L = lua_open();
luaL_openlibs(L);
// Initialize Luabind.
luabind::open(L);
// Initialize a Luabind module.
luabind::module(L)
[
luabind::def("Greet", &greet)
];
// Close down Lua.
if (L)
{
lua_close(L);
L = NULL;
}
}
When I compile, I get a massive amount of errors that look like this:

What have I missed? I tried looking at the official Luabind guide, some Ogre3D guide and a couple of other (and very similar) guides, but they reveal nothing that I could have missed, except the part where they say it is optional to build Luabind with Boost-Build.
