OOLua compile errors
Question
How can it be fixed?
Solution
class foo
{
public:
int bar()
{
return 0;
}
};
OOLUA_CLASS_NO_BASES(foo)//class has no bases
OOLUA_NO_TYPEDEFS
OOLUA_MEM_FUNC_0(int,bar)
OOLUA_CLASS_END
EXPORT_OOLUA_FUNCTIONS_1_NON_CONST(foo /*name of class*/
,bar)/*function being exposed*/
EXPORT_OOLUA_FUNCTIONS_0_CONST(foo)
void test()
{
OOLUA::Script s;
s.register_class<foo>();
}
http://code.google.com/p/oolua/wiki/CheatSheet#Has_a_member_function_which_takes_no_parameters
Then in a source file expose the class telling the framework that the instance has a function of interest yet no constant member functions, also providing the name it will be identified by in Lua code(foo).
EXPORT_OOLUA_FUNCTIONS_1_NON_CONST(foo /*name of class*/
,bar)/*function being exposed*/
EXPORT_OOLUA_FUNCTIONS_0_CONST(foo)
