使用Eclipse编译C ++文件时错误在Android中NDK项目 [英] Errors when building C++ files in Android NDK project using Eclipse

问题描述

我一直有钩住了Android NDK到Eclipse IDE中工作的一些实际问题。

具体来说，我一直在尝试使用NDK与OpenCV的工作，因此我已经下载了OpenCV的样品，其中包括一个项目，不上镜头框架面部识别。

这个项目，一段时间后，我设法得到充分在Eclipse中工作。 NDK的建筑工程一样，Eclipse中的索引器。当我更改了C ++ code的东西，它建立正确吧...一切正常。

然而，然后是我的问题：我要创造我自己的项目。要做到这一点，我决定这是一个好主意，首先是对面此示例项目复制为基地，并从那里更改。有一次，我已经复制这个项目，但是，生成错误出现 - JNI的C ++文件显示错误的负载，当我做出改变，他们不建（所以我不认为这只是一个索引的问题）。

有谁知道，不会被转移设置时，我将项目以这种方式？我已经尝试了所有的比较我已经玩到这一点，试图把它打造的设定。

我希望这个问题不是太含糊。让我知道如果有任何更多的信息，我可以添加，使其更清晰。

在OpenCV的样品配OpenCV4Android，也可以在这里下载： http://opencv.org/downloads.html

在此先感谢！

解决方案

转到 项目属性 - ＆GT; C / C ++编译 - ＆GT;工具链编辑器 ，设置当前工具链为 Android的GCC 和当前的建设者为 Android的生成器
那么选择工具和替换编译器的 GCC C ++编译器

那么你应该设置路径到你的头文件。

结果

I have been having some real problems hooking up the Android NDK to work within the Eclipse IDE.

Specifically, I have been trying to use the NDK to work with OpenCV, and as such I have downloaded the OpenCV samples, which include a project that does facial recognition on camera frames.

This project, after some time, I have managed to get fully working in Eclipse. The NDK building works, as does the indexer within eclipse. When I change something in the C++ code, it builds it correctly... everything works.

However, then comes my problem: I want to create my own project. To do this I decided it was a good idea firstly to just copy across this sample project as a base, and change it from there. Once I have copied this project, however, the build errors appear - the jni C++ files show loads of errors, and when I make changes they do not build (so I don't think this is just an indexing issue).

Does anyone know of settings that would not be transferred when I copy the project in this way? I have tried comparing all of the settings I have been playing with up to this point to try and get it to build.

I hope this question is not too vague. Let me know if there is any more info I could add, to make it more clear.

The OpenCV samples come with OpenCV4Android, that can be downloaded here: http://opencv.org/downloads.html

Thanks in advance! Chris

解决方案

Go to Project properties -> C/C++ Build -> Tool Chain Editor, set Current toolchain to Android GCC and current builder to Android Builder then select tools and replace compiler with GCC C++ Compiler.

Then you should set Paths to your header files.
