Enoim 程式開發筆記 : Cocos2d-x 錯誤訊息記錄

1.
[armeabi] Compile++ thumb: cocos2dcpp_shared <= AppDelegate.cpp
jni/../../Classes/AppDelegate.cpp: In member function 'virtual bool AppDelegate::applicationDidFinishLaunching()':
jni/../../Classes/AppDelegate.cpp:20:44: error: 'ResolutionPolicy' is not a class or namespace
make.exe: *** [obj/local/armeabi/objs/cocos2dcpp_shared/__/__/Classes/AppDelegate.o] Error 1

ANS:

The syntax MyEnum::SomethingElse is a Microsoft extension. It happens to be one I like, but it's not Standard C++. enum values are added to the surrounding namespace:

 // header
 enum MyEnum {Something = 0, SomethingElse = 1};

 class MyClass {

 MyEnum enumInstance;
 void Foo();

 }

 // implementation
 #include "MyClass.h"

 void Foo() {
     enumInstance = SomethingElse;
 }

意思是說ResolutionPolicy::kResolutionShowAll 是 Microsoft extension
用 jni 的話就看不懂了... 只要寫 kResolutionShowAll 就好。

ANS:
新增.cpp 檔案要把檔案加入 android.mk 裡面... 不然會找不到。
