  1.   Sorry about that, I didn't actually compile that pasted code. But anyways I compile it now the result is: 8 function: 0056D180     Basically, .def_readwrite and .property don't really work. I found 2 similar questions with google and it appears that its a wrong build with either boost or luabind. here: http://www.gamedev.net/topic/593408-def-readwrite-dosent-work/ and here: http://lua.2524044.n2.nabble.com/problems-using-def-readwrite-and-property-when-binding-classes-td7581631.html   The thing is... I can't seem to compile boost or luabind very well... I'm using Code::Block with gcc mingw. What I did was compile luabind from a dynamic lib project with defined LUABIND_DYNAMIC_LINK   As for the boost I simply extrated boost 1_44_0 and added it to the includes directories and it seemed to work fine.   Can someone help me compile boost and luabind correctly??
  2. Just to follow up, LuaBind an tolua++ are REALLY easy and simple to bind C++ classes to lua.   Here is a tutorial of how to bind classes with LuaBind: http://blog.nuclex-games.com/tutorials/cxx/luabind-introduction/   You might have some problems in windows if you're new to programming thought. I didn't find any compiled luabind for windows, but even so, its fairly easy to compile it from source code and the luabind manual has every instructions you might need to help you with that.
  3. EDIT 2:   Solved!   As I couldn't compile luabind with gcc using bjam, I created a new static library project for Lua 5.1.4 and Luabind and it finally worked as it should.   I was using the installer version of Lua 5.14 for windows before, which was a dynamic library   and I guess it was messing with the static lib project for luabind I created previously.   But anyways, its working now.... Thanks o/ And nice tip Gambini, that helps a lot when debugging.     EndEdit2     Edit: It really is the build of luabind. I download VisualStudio and compiled luabind with:  "bjam toolset=msvc-10.0 variant=debug threading=multi link=static" -> This doesnt solve anything, the same result and  "bjam toolset=msvc-10.0 variant=debug threading=multi link=static define=_BIND_TO_CURRENT_VCLIBS_VERSION" -> This makes it work.   The only problem is that I use gcc mingw with code::blocks so that doesn't actually solve it. The define that solves the problem is specific to msvc.    just to make sure, now compiling luabind with gcc(gcc-mingw-4.4.1) with the define produces:  "bjam toolset=gcc variant=debug threading=multi link=static define=_BIND_TO_CURRENT_VCLIBS_VERSION" -> Bunch of undefined references to lua functions "bjam toolset=gcc variant=debug threading=multi link=shared define=_BIND_TO_CURRENT_VCLIBS_VERSION" -> Luabind works but with .def_readwrite and .property not working still   Does anyone know how to properly compile luabind with gcc?       EndEdit:   I'm trying to make lua recognize a local variable in his global scope and makes chances in it. So I'm creating a Test ts; and passing it to lua with luabind::globals(l)["test"] = &ts;   It works fine, lua makes changes to his variable 'test' and the changes are transferred to the local variable 'ts'.   The only problem is that the Property is not working: ".property("stack", &Test::getStack, &Test::setStack)" When calling the getter it spills out some random numbers I'm assuming is an memory addres and the setter does nothing.   I notice thought that this doesnt happen when the variable is created inside luaString, only when getting a variable with luabind::globals.   Inside luaString: "t = Test()\n print(t.stack)" <- this works fine, just doesnt when variable from luabind::globals   This is not a major problem but it would be nice to know how to solve this... am I doing something wrong or am missign something?     The class using namespace std; class Test { private: int stack; public: Test(){stack = 0; valor = 2;} ~Test(){} void addStack(){stack++;} void sayStack(){cout << stack << endl;} int getStack(){return stack;} void setStack(int stk){stack = stk;} };   Example main and Lua code   int main() { lua_State* l = luaL_newstate(); luaL_openlibs(l); luabind::open(l); //Bind the class to lua luabind::module(l) [ luabind::class_<Test>("Test") .def( luabind::constructor<>( ) ) .def("sayStack", &Test::sayStack) .def("addStack", &Test::addStack) .property("stack", &Test::getStack, &Test::setStack) ]; //Create a Test class Test ts; //Make lua global test equal to local ts luabind::globals(l)["test"] = &ts; //First, make a new variable and test property, it WORKS luaL_dostring(l, "t = Test()\n" "t.stack = 8\n" "print(t.stack)\n" ); //Then, using the variable grom luabind::globals... DOESN'T WORK. luaL_dostring(l, "print(ts.stack)\n" "ts.stack = 8\n" "print(ts.stack)\n" ); //Close lua lua_close(l); return 0; }   Thanks   
  4. Hey, I just began learning luabind and I'm trying to get the .property getter to work but with no luck. When I set the getter to a lua variable and try to print it... it prints the function address instead of the value. I made a simple program to test it here: [code] using namespace std; class Test { private: int stack; public: Test(){stack = 0;} ~Test(){} void addStack(){stack++;} void sayStack(){cout << stack << endl;} int getStack(){return stack;} void setStack(int stk){stack = stk;} }; int main() { lua_State* l = luaL_newstate(); luaL_openlibs(l); luabind::open(l); //Bind the class to lua luabind::module(l) [ luabind::class_<Test>("Test") .def("sayStack", &Test::sayStack) .def("addStack", &Test::addStack) .property("stack", &Test::getStack, &Test::setStack) ]; //Create a Test class Test ts; //Make lua global test equal to local ts luabind::globals(l)["test"] = &ts; //Should make rs = stack, //Say stack and then print the rs(print same as sayStack) luaL_dostring(l, "rs = test.stack\n" "test:sayStack()\n" "print(rs)\n" ); //Close lua lua_close(l); return 0; } [/code] The output here: [code] 0 function: 005FC568 [/code] I tried the setter and it works just fine.... its just the getter that doesnt work. Does anybody have an idea why and how to get the getter to work?
