luabind 0.8.1 + lua 5.1.4: passed object pointers are userdata

Hello, I've faced the problem with passing registered class object's pointer to lua. It is not resolved to table somewhy. I've traced with a debugger and the algorithm seems went well - there were proper calls of lua_setmetatable and lua_settable.
The code is like in the basic example: class TestClass { public: TestClass() {} void Test() { printf("Hello\n"); } }; TestClass obj; lua_State *state = lua_open(); luabind::open(state); luabind::module(state)[ luabind::class_<TestClass>("TestClass") .def(luabind::constructor<>()) .def("Test", &TestClass::Test) ]; if (luaL_loadstring(state, "function main(c) c:Test() end") != 0 || lua_pcall(state, 0, LUA_MULTRET, 0) != 0) { ErrorHandle(state); } if (luaL_loadstring(state, "obj = TestClass(); main(obj)") != 0 || lua_pcall(state, 0, LUA_MULTRET, 0) != 0) { ErrorHandle(state); } luabind::globals(state)["tmp"] = &obj; if (luaL_loadstring(state, "main(tmp)") != 0 || lua_pcall(state, 0, LUA_MULTRET, 0) != 0) { ErrorHandle(state); } lua_close(state); ----------------------- Output: Hello [string "function main(c) c:Test() end"]:1: attempt to index local 'c' (a userda ta value) Could you please give me some hint how to overcome this problem? :) Regards, _dm ------------------------------------------------------------------------------ Come build with us!

Your code works for me (luabind 0.8.1, lua 5.1.4, VC2005/Win32,
luabind as dll). If you are on Windows, double-check LUABIND_DYNAMIC_LINK macro consitency i.e. if you are building luabind as dll, make sure that both the library and your program are compiled with LUABIND_DYNAMIC_LINK defined; and if compiling luabind to static library - make sure the macro is not defined for both luabind and your program.

Sorry for mistaken posting.
And thank you, everything works fine now! I added LUABIND_DYNAMIC_LINK to the program project and everything is cool:). However it's weird, as previous version of luabind didn't need such tricks. Thanks a lot. -----Original Message----- From: Ilia Trendafilov <itrend@...> To: Dmitriy Mazovka <mazovka@...>, luabind-user@...
