仅在eclipse中打开hello-jni.c文件时才在eclipse中编译Hello-Jni失败 [英] Compiling Hello-Jni failure in eclipse only when opening the hello-jni.c file in eclipse

问题描述

我一直在努力为Android NDK构建示例HelloJni示例项目。

我如何设置环境： / p>

我按照开始在文档中的说明进行操作：android-ndk-r10d\docs\Getting_Started / html / index.html：

1. 下载的Eclipse Luna


2. 下载Android SDK


3. 下载Android NDK： android-ndk-r10d


4. 在首选项窗口 - > android - > NDK中设置日食中的NDK安装文件夹。 >
   
5. 导入hellp-jni示例


6. 右键单击HelloJni项目 - > Android工具 - >添加本机支持。



7. 在我的设备上放置HelloJni库（不是测试）

应用程序正在运行，一切都在工作，我可以看到生成的.so文件每个架构的libs文件夹中的项目（对于每个架构，例如armebi，mips等）

这是一个打印屏幕，显示一切正常工作： / p>

现在这里是奇怪的部分...

问题：

如果我打开hello-jni.c文件在eclipse中进行编辑或查看，我突然看到编译错误，我无法构建，也无法再运行该项目...

这是一个打印屏幕，显示我打开文件后，我突然收到编译错误：

我已经尝试过了失败：

1. 添加Android Native Nature，然后将其删除：
   删除.project文件
   buildCommand标签：org.eclipse.cdt.managedbuilde r.core.genmakebuilde，
   buildCommand标签：org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder
   并删除行：
   [nature] org.eclipse.cdt.core。 cnature [/ nature]
   [nature] org.eclipse.cdt.core.ccnature [/ nature] [nature] org.eclipse.cdt.managedbuilder.core.managedBuildNature [/ nature] [nature] org.eclipse。 cdt.managedbuilder.core.ScannerConfigNature [/ nature]
   删除.cproject和所有编译文件。
   然后添加Android Native Nature。

根据这个stackoverflow链接：

这是一个打印屏幕：

失败

4. 从项目为他工作的朋友复制eclipse Luna安装。

失败

我已经花了几个小时，我找不到任何解决这个问题的解决方案。

请帮助

解决方案

FWIW，Eclipse似乎有与 r10d 版本的问题的Android NDK。请参阅 https://code.google.com/p/android/issues/细节？ID = 97023 。我建议您尝试 r10c 而不是#worksforme：）

I have been trying endlessly to build the sample HelloJni sample project for the Android NDK.

How I set up the environment:

I followed the instructions of the getting started in the docs: android-ndk-r10d\docs\Getting_Started/html/index.html:

1. Downloaded Eclipse Luna
2. Downloaded the Android SDK
3. Downloaded the Android NDK: android-ndk-r10d
4. Set the NDK installation folder in eclipse in preferences window -> android -> NDK.
5. Imported the hellp-jni sample.
6. Right click on the HelloJni Project -> Android tools -> Add native support.
7. Cleaned and Built the project.
8. Ran on my device the HelloJni library (not the tests)

And the app is running and everything is WORKING and I can see the generated .so file per architecture in the libs folder of the project (for every architecture, for example armebi, mips, etc...)

Here is a Print Screen showing everything is working:

Now here comes the strange part...

The Problem:

If I open the hello-jni.c file for editing or viewing in eclipse, I suddenly see compilation errors and I can't build and can't run the project anymore...

Here is a Print Screen showing that after i open the file, I suddenly get compilation errors:

What I have already tried but failed:

1. Adding the Android Native Nature, then removing it by: Deleting the .project file, the buildCommand tag of: org.eclipse.cdt.managedbuilder.core.genmakebuilde, the buildCommand tag of: org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder and removing the lines: [nature]org.eclipse.cdt.core.cnature[/nature] [nature]org.eclipse.cdt.core.ccnature[/nature] [nature]org.eclipse.cdt.managedbuilder.core.managedBuildNature[/nature] [nature]org.eclipse.cdt.managedbuilder.core.ScannerConfigNature[/nature] removing the .cproject and all compiled files. Then adding back the Android Native Nature.

According to this stackoverflow link: Eclipse ADT - Unresolved inclusion jni.h

Failed

2. Once I got the error of (I am not getting it anymore): Unable to launch cygpath. Is Cygwin on the path?] java.io.IOException: Cannot run program "cygpath". So I Googled and I changed the build settings to give the absolute path of my NDK installation folder:

According to this stackoverflow link: Unable to launch cygpath in android

Here is a Print Screen:

Failed

3. Changing the Used tools from Android GCC Compiler to GCC C Compiler

according to this stackoverflow link: Android NDK build, Method could not be resolved

Here is a Print Screen:

Failed

4. Copying an eclipse Luna installation from a friend that has the project working for him.

Failed

I have been spending hours on this and I couldn't find any solution to why this is happening.

PLEASE HELP

解决方案

FWIW, Eclipse seems to have issues with the r10d version of Android NDK. See https://code.google.com/p/android/issues/detail?id=97023. I suggest you try r10c instead #worksforme :)
