Cocos2dx移植到Android平台后编译报错

srand ((unsigned)time(nullptr)); 报错
jni/../../Classes/UILayer.cpp: In member function 'void UILayer::NPCfapai()':
jni/../../Classes/UILayer.cpp:144:24: error: 'nullptr' was not declared in this scope
make: *** [obj/local/armeabi/objs/cocos2dcpp_shared/__/__/Classes/UILayer.o] Error 1

音效也报错
Unresolved inclusion: "SimpleAudioEngine.h"
Symbol 'CocosDenshion' could not be resolved

SimpleAudioEngine::sharedEngine()->playEffect("wav/peng.wav");
Function 'sharedEngine' could not be resolved

Answer 1

1. C++11 没有很深入了解，srand ((unsigned)time(nullptr));  是否考虑换回srand ((unsigned)time(NULL));    或者用CCRANDOM_0_1(3.0是否还有这个不知道了）

2. 是否在jni/Android.mk中的LOCAL_WHOLE_STATIC_LIBRARIES添加cocosdenshion_static？

Answer 2

nullptr是C++11的新特性 但是NDK还并未对其支持 换回NULL就行了
