OpenCV的opencv2 /核心/ core.hpp：没有这样的文件或目录 [英] OpenCV opencv2/core/core.hpp: No such file or directory

问题描述

我创建一个小的项目，在Android 1.4工作室测试的OpenCV（2.4），但是当我尝试执行该应用程序，我有一个问题与NDK编译器。我认为cpp文件找不到路径OpenCV的，但我不知道为什么。

任何IDEIA如何解决这个问题？

错误：

解决方案

有你只尝试的#include＆LT; opencv2 / core.hpp＆GT; （而不是的#include＆LT; opencv2 /核心/ core.hpp＆GT; ）？
这为我工作（Ubuntu的14.04和OpenCV 2.4）。

I'm creating a small project to test the opencv (2.4) on Android Studio 1.4 but when I try execute the app I have one problem with the NDK compiler. I think that the cpp files can't find the path to opencv but I dont know why.

Any ideia how to fix this problem??

Error: Warning:Native C/C++ source code is found, but it seems that
NDK option is not configured.  Note that if you have an Android.mk, it is
not used for compilation.  The recommended workaround is to remove the
default jni source code directory by adding:

 android {
    sourceSets {
        main {
            jni.srcDirs = []
        }
    }
}    

to build.gradle, manually compile the code with ndk-build, and then
place the resulting shared object in src/main/jniLibs.

解决方案

Have you tried only #include <opencv2/core.hpp> (instead of #include <opencv2/core/core.hpp>)? That worked for me (ubuntu 14.04 and opencv 2.4).
