Question

所有

我有问题在Android NDK中使用支持c ++ 11编译opencv库，我有一个配置opencv 2.4.11的项目，我需要使用一些支持c ++ 11的类，但是当我启用c +时项目中的+11并使用Android NDK进行编译，该项目无法正常工作。

我做了下一个内部jni文件夹：

在下一个文件中启用c ++ 11：

Android.mk文件

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
OPENCV_CAMERA_MODULES:=off
OPENCV_INSTALL_MODULES:=off
OPENCV_LIB_TYPE:=STATIC
include /OpenCV-android-sdk/sdk/native/jni/OpenCV.mk
LOCAL_SRC_FILES  := DetectionBasedTracker_jni.cpp
LOCAL_C_INCLUDES += $(LOCAL_PATH)
LOCAL_LDLIBS     += -llog -ldl
LOCAL_MODULE     := detection_based_tracker
include $(BUILD_STATIC_LIBRARY)

Application.mk文件

//change gnustl_static to c++_static
APP_STL := c++_static
//add -std=c++11 to enable support c++11
APP_CPPFLAGS += -std=c++11 -frtti -fexceptions
APP_ABI :=  armeabi-v7a
APP_PLATFORM := android-13
NDK_TOOLCHAIN_VERSION := 4.8

当我使用NDK命令编译ndk-build时，我有下一个错误：

OpenCV-android-    sdk/sdk/native/jni/include/opencv2/core/operations.hpp:77:29: fatal error: atomicity.h: No such file or directory #include <atomicity.h>

你能帮我解决问题吗，谢谢你。

执行ndk-build V = 1
