[Lua] Install on Windows

Build

> cl /MD /O2 /c /DLUA_BUILD_AS_DLL *.c

This line compiles all files in the directory with the ".c" extension without linking them (/c) with the fastest possible (/O2) multithreaded (/MD) code

NOTICE! IN THE NEXT FEW STEPS X.X MEANS YOUR CURRENT LUA VERSION NUMBER, E.G. 5.2

> link /DLL /IMPLIB:luaX.X.lib /OUT:luaX.X.dll *.obj

This will create luaX.X.dll and luaX.X.lib out of all ".obj" files

REMEMBER TO RENAME "lua.obj" AND "luac.obj" WITH THE EXTENSION ".o" SO THEY WON'T BE SELECTED!!

> link /OUT:lua.exe lua.o luaX.X.lib

This will create lua.exe (interpreter) from lua.o using the luaX.X.lib library

> lib /OUT:luaX.X-static.lib *.obj

This will create luaX.X-static.lib from all ".obj" files, similar to step 2, but with no dll and this is using the "lib" command

> link /OUT:luac.exe luac.o luaX.X-static.lib

This will create luac.exe (compiler) from luac.o using the luaX.X-static.lib library

This is how I do my directories (parentheses indicate what the folder represents). This also shows notable file locations.

File Hierarchy

Lua

Set Environment Variables

(? represents a wildcard)

The lua install directory

LUA_DIR = C:\Program Files\Lua\X.X

Where to look for .dll files (C libraries)

LUA_CPATH = ?.dll;%LUA_DIR%\?.dll

Where to look for .lua files (Lua libraries)

LUA_PATH = ?.lua;%LUA_DIR%\lua\?.lua

Also add the contents of LUA_DIR to PATH

Lua 5.2 test code

function is_even(n)
    if bit32.band(n,1) == 0 then -- fancy bitwise way to check if a number if even (5.2+ only)
        print('Even')
    else
        print('Odd')
    end
end

To setup in Visual Studio 2012

go to C/C++ -> General and add $(LUA_DIR)\include to additional include directories.

go to Linker -> General and add $(LUA_DIR)\lib to additional library dir

go to Linker -> Input and add luaX.X.lib to additional dependencies.

C API test code

#include "stdio.h"
#include "lua.hpp" // C++ header for the C API
 
int main(int argc, char** argv) {
    lua_State *L = luaL_newstate();

    // Open the default Lua libraries
    luaL_openlibs(L);
 
    if (luaL_dofile(L, "test.lua")) { // Execute the file
        // If there was an issue, get the string from the top of the stack...
        printf("%s\n", lua_tostring(L, -1));
    }

    // Close the lua state
    lua_close(L);

    getchar();
    return 0;
}
