VC编译LUA与调用

环境vs2010，lua版本5.2新件一个空项目，添加所有src内的文件，然后移除lua.c, lua.h, luac.c, print.c文件.

选择项目-属性-配置属性-常规-配置类型,即可选择生成静态库或动态库.

下面演示一个c++调用lua函数的例子.

test.lua代码

function MaxMin(x, y)if x > y thenreturn "x > y", x, yelseif x == y thenreturn "x = y", x, yelsereturn "y > x", y, xendend

c++代码

extern "C" {#include "../lua5.2/src/lua.h"#include "../lua5.2/src/lauxlib.h"#include "../lua5.2/src/lualib.h"};#pragma comment(lib, "../Release/lua5.2.lib")void MaxMin(lua_State* L, int x, int y){lua_getglobal(L, "MaxMin");//参数1lua_pushnumber(L, x);//参数2lua_pushnumber(L, y);//2个参数,3个返回值lua_pcall(L, 2, 3, 0);const char* c = lua_tostring(L, -3);lua_Number n1 = lua_tonumber(L, -2);lua_Number n2 = lua_tonumber(L, -1);cout<<c<<"  "<<"Max = "<<n1<<", Min = "<<n2<<endl;//元素出栈lua_pop(L, 3);}int _tmain(int argc, _TCHAR* argv[]){lua_State* L = luaL_newstate();if(!luaL_loadfile(L, "d:\\test.lua")){if(!lua_pcall(L, 0, 0, 0)){MaxMin(L, 1, 2);MaxMin(L, 3, 3);MaxMin(L, 9, 8);}}lua_close(L);return 0;}

输出结果:

y > x  Max = 2, Min = 1x = y  Max = 3, Min = 3x > y  Max = 9, Min = 8请按任意键继续. . .
