I'm running Mac OS 10.5.5 and Using Xcode 3.1.1 and Lua 5.1.4. I'm trying to embed Lua into my C++ application. When I build it, at the linker stage I get the following errors: "lua_pcall(lua_State*, int, int, int)", referenced from: vConsole::run() in main.o "luaL_newstate()", referenced from: initVLua() in main.o "luaL_openlibs(lua_State*)", referenced from: initVLua() in main.o "lua_close(lua_State*)", referenced from: vEngine::~vEngine()in main.o "luaL_loadstring(lua_State*, char const*)", referenced from: vConsole::run() in main.o Xcode should be linking against liblua.a, and I've tried using different versions, all of which give me the same errors. My (relevant) project code looks like this: #include "lua.h" #include "lualib.h" #include "lauxlib.h" ... static lua_State* LUA; ... LUA = lua_open(); luaL_openlibs(LUA); ... luaL_loadstring(LUA, comstr); lua_pcall(LUA, 0, 0, 0); ... lua_close(LUA); I googled for about an hour looking for a solution and it's really driving me crazy. If anyone could help out, I would greatly appreciate it. Thanks.
