在Eclipse开放的Hello-jni.c文件只在编译HELLO-JNI故障日食 [英] Compiling Hello-Jni failure in eclipse only when opening the hello-jni.c file in eclipse

问题描述

我一直在试图不断地打造为Android NDK样本HelloJni示例项目。

如何设置环境：

我跟着的指令得到的文档开始：Android的NDK-r10d \文档\ Getting_Started / HTML / index.html的：

1. 下载的是Eclipse的红月
2. 下载了Android SDK
3. 下载了Android NDK：的Andr​​oid NDK-r10d
4. 设置NDK的安装文件夹在eclipse在preferences窗口 - >机器人 - > NDK
5. 进口HELLP-JNI样品。
6. 右键点击HelloJni项目 - > Android的工具 - >添加原生支持
。
7. 清理在建和建成项目。
8. 然我的设备上的HelloJni库（未测试）

和应用程序正在运行，一切正常，我可以看到生成的每个建筑.so文件在项目的libs文件夹（为每个架构，例如armebi，MIPS，等...）

下面是打印屏幕显示的一切工作：

现在，这里是陌生的一部分......

的问题：

如果我打开HELLO-jni.c文件进行编辑或查看日食，我突然看到编译错误，我不能建立，不能运行该项目了...

下面是打印屏幕显示后，我打开文件的时候，突然出现编译错误：

我已经尝试过什么，但失败了：

1. 添加了Android原生自然，然后将其取出： 删除项目文件， 的buildCommand标签：org.eclipse.cdt.managedbuilder.core.genmakebuilde， org.eclipse.cdt.managedbuilder.core.ScannerConfigBuilder：的buildCommand标签 和除去行： [自然] org.eclipse.cdt.core.cnature [/本性] [自然] org.eclipse.cdt.core.ccnature [/本性] [自然] org.eclipse.cdt.managedbuilder.core.managedBuildNature [/本性] [自然] org.eclipse.cdt.managedbuilder.core.ScannerConfigNature [/性质] 除去.cproject和所有编译后的文件。 然后加回了Android原生自然。

有一次，我（再我没有得到它）​​得到的错误：无法启动cygpath。是Cygwin的路径上]产生java.io.IOException：不能运行程序cygpath。所以，我用Google搜索，我改变了构建设置给我的NDK安装文件夹的绝对路径：

更改从Android的GCC编译的使用工具GCC C编译器

复制从朋友处得知了这个项目为他工作的日食月亮安装。

失败

我已经花时间在这，我找不到任何解决方案，为什么会这样。

请帮助

解决方案

FWIW，Eclipse的似乎与在 r10d 版本的Andr​​oid NDK的问题。请参见的https：//$c$c.google.com/ P /安卓/问题/详细信息？ID = 97023 。我建议你​​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 :)
