也许你能帮我把这件事做好。我有一个用于画圆的类,但编译器向我发送了这条消息:
In file included from ./Includes.h:19,
from ./Circle.h:8,
from ./Circle.cpp:5:
./GameApp.h:24: error: ISO C++ forbids declaration of 'Circle' with no type
./GameApp.h:24: error: expected ';' before '*' token
这是GameApp.h:
#include "Includes.h"
class GameApp {
public:
GameApp();
~GameApp();
void Render();
protected:
void InitGU();
bool Controls();
void *dList; // display List, used by sceGUStart
void *fbp0; // frame buffer
Circle* circle;
};
Include.h 看起来像这样:
//************************************************************************
// Includes.h
//************************************************************************
#include <malloc.h> //For memalign()

#include <pspdisplay.h>

还有 Circle.h
