代码

#include <OOLua/oolua.h>

class foo
{
public:
  int bar();
};

OOLUA_CLASS_NO_BASES(foo)//class has no bases
    OOLUA_NO_TYPEDEFS
    OOLUA_MEM_FUNC_0(int,bar)
OOLUA_CLASS_END

void test()
{
    OOLUA::Script s;
    s.register_class<foo>();
}

编译器输出

OOLua 编译错误

问题

如何修复？

解决方案

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>();
}

然后在源文件中公开类，告诉框架该实例有一个感兴趣的函数但没有常量成员函数，还提供它将在 Lua 代码中标识的名称（foo）。

EXPORT_OOLUA_FUNCTIONS_1_NON_CONST(foo /*name of class*/
                                  ,bar)/*function being exposed*/
EXPORT_OOLUA_FUNCTIONS_0_CONST(foo)
