使用的是lua5.3
DllMain.cpp
1 //生成的dll 是 lua_add53.dll 2 //luaopen_lua_add 3 extern "C" { 4 #include "F:/lua_src/lua-5.3.5_Win64_vc15_lib/include/lua.h" 5 #include "F:/lua_src/lua-5.3.5_Win64_vc15_lib/include/lualib.h" 6 #include "F:/lua_src/lua-5.3.5_Win64_vc15_lib/include/lauxlib.h" 7 }; 8 #pragma comment(lib, "F:/lua_src/lua-5.3.5_Win64_vc15_lib/lua53.lib") 9 10 #include <iostream> 11 using namespace std; 12 13 extern "C" int ShowMsg(lua_State* luaEnv) { 14 cout << "Hello world from clibs!" << endl; 15 return 0; // 返回值个数为0个. 16 } 17 18 extern "C" int sub2(lua_State* L) 19 { 20 double op1 = luaL_checknumber(L, 1); 21 double op2 = luaL_checknumber(L, 2); 22 int temp = op1 - op2; 23 lua_pushnumber(L, temp); 24 return 1; 25 } 26 27 // part one: 要导出的函数列表 28 static luaL_Reg luaLibs[] = { 29 { "ShowMsg", ShowMsg}, 30 { "sub2", sub2}, 31 { NULL, NULL } 32 }; 33 34 // part two: DLL入口函数,Lua调用此DLL的入口函数. 35 extern "C" __declspec(dllexport) 36 int luaopen_lua_add(lua_State* luaEnv) { //WinFeature是modole名, 将来require这个名字 37 //lua_register(luaEnv, "ShowMsg", ShowMsg); //关键一行, 在luaState上注册好这个lib 38 //lua_register(luaEnv, "sub2", sub2); //关键一行, 在luaState上注册好这个lib 39 lua_newtable(luaEnv); 40 luaL_setfuncs(luaEnv, luaLibs,0); 41 return 1; 42 }
编译后是 lua_add53.dll
lua
1 local mytest = require "lua_add" 2 mytest.ShowMsg(); 3 print(mytest.sub2(1,2));
