Question

我使用Cocos2D-x编写了基本游戏。它在iPhone上运行良好。现在我正在尝试将其移植到Android。当我运行脚本时，它给出了以下错误：

jni/../../Classes/MemoryModeLayer.cpp: In member function 'void MemoryModeLayer::startNewGame()':
jni/../../Classes/MemoryModeLayer.cpp:109:25: error: 'time' is not a member of 'std'
jni/../../Classes/MemoryModeLayer.cpp:109:25: note: suggested alternative:
/Users/abc/android-ndk-r9d/platforms/android-8/arch-arm/usr/include/time.h:40:17: note:   'time'
jni/../../Classes/MemoryModeLayer.cpp:111:5: error: 'random_shuffle' is not a member of 'std'
jni/../../Classes/MemoryModeLayer.cpp:112:5: error: 'random_shuffle' is not a member of 'std'
make: *** [obj/local/armeabi/objs/cocos2dcpp_shared/__/__/Classes/MemoryModeLayer.o] Error 1
make: Leaving directory `/Users/anil/cocos2d-x-2.2.3/projects/Game/proj.android'

在MemoryModeLayer.cpp中我有以下内容：

std::srand(unsigned(std::time(0)));
std::random_shuffle(_xCod, _xCod + _numberOfRows);
std::random_shuffle(_yCod, _yCod + _numberOfColumns);

我还包括以下标题：

#include <string>
#include <ctime>
#include <algorithm> 
#include <iostream>
#include <iomanip>

还在头文件中添加了using namespace std。还有什么我应该做的吗？

Answer 1

您需要#include <random>

Answer 2

Application.mk文件存在问题。不得不像这样更改STL库查找：

将APP_STL := stlport_static添加到Application.mk文件中。它可能已经有APP_STL := gnustl_static。

以下博客文章非常有帮助！
