Question

使用Cocos-2dx和Clang进行构建时，我在Android NDK中出现以下错误

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

Answer 1

我认为您没有链接器错误。您有编译器错误。问题是，你没有在你的应用程序中提到C ++ 11的支持。您必须使用Clang附带的那个，方法是在-std=c++11文件夹中的APP_CPPFLAGS文件中指定Application.mk编译器标志（jni）。即。

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

Answer 2

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，Android版本需要这样做，但iOS版本不需要。我想它已包含在别处。

我遇到了同样的问题，并通过以下方式解决了它：

在 Android.mk 文件中，添加

LOCAL_CPP_EXTENSION += .h

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