Android NDK - 命名空间'std'中没有名为 'function' 的类型

Android NDK - no type named 'function' in namespace 'std'

在使用 Cocos-2dx 和 Clang 构建时，我在 Android NDK 中不断收到以下错误

jni/../../Classes/Facebook/FacebookConstants.h:44:14: error: no type named 'function' in namespace 'std'
typedef std::function<void()> FacebookLoginCallback;

我认为您没有链接器错误。您有一个编译器错误。问题是，您的应用程序中没有提及对 C++11 的支持。您必须通过在jni文件夹中的文件中指定-std=c++11编译器标志(APP_CPPFLAGS(来使用Clang附带Application.mk标志。即

APP_CPPFLAGS := -frtti -DCC_ENABLE_CHIPMUNK_INTEGRATION=1 -DCOCOS2D_DEBUG=1 -std=c++11

不要忘记将其包含在标题中

#include <functional>

在我的项目 cocos2d-x v3.0.0 中，这是 Android 构建所必需的，但 iOS 不需要。我想它包含在其他地方。

我有同样的问题，并通过执行以下操作来重新喜欢它：

在 Android.mk 文件中，添加

LOCAL_CPP_EXTENSION += .h
