Eclipse的编译成功，但仍给语义错误 [英] Eclipse compiles successfully but still gives semantic errors

问题描述

注：这显然是一个计算器反复发作的问题，而是 - 为我所看到的 - 无论是人从来没有找到一种方法，或者他们的解决方案不适合我的

我使用Eclipse ADT朱诺。一切工作正常，直到我试图更新NDK。我取代我的 NDK 文件夹（也就是 NDK-r8d ）的新版本（即 NDK-R8E ），并在我的路径和符号配置，我改变了包括来自G ++ 4.6去4.7。

I am using Eclipse Juno ADT. Everything was working fine until I tried to update the NDK. I replaced my ndk folder (that was the ndk-r8d) by the new version (i.e. ndk-r8e) and, in my Paths and Symbols configuration, I changed the includes to go from g++ 4.6 to 4.7.

这似乎打破我的索引：我可以编译我的code，但是Eclipse正在给语义错误，酷似[<一href="http://stackoverflow.com/questions/15612673/eclipse-cdt-displays-semantic-error-but-builds-successfully">1]和[<一href="http://stackoverflow.com/questions/10103465/eclipse-cdt-complains-about-unresolved-functions-but-still-builds-successfully">2].这些错误的主要的来自符号使用OpenCV4Android，如距离， PT ， queryIdx 和 trainIdx 。

It seemed to break my index: I could compile my code, but Eclipse was giving semantic errors, exactly like in [1] and [2]. The errors mainly come from symbol used by OpenCV4Android, such as distance, pt, queryIdx and trainIdx.

当我试图备份到我的旧配置，该指数仍打破！我无法找到一个方法来改变这种状况。

When I tried to backup to my old configuration, the index was still broken! I cannot find a way to change this.

• 清理项目
• 重建，更新，和所有其他的索引子菜单选项（当右击的项目）
• 禁用/启用在preferences索引
• 验证，如 trainIdx 符号只会出现在我的OpenCV4Android包括在路径和符号部分。
• 更改订单我包括在路径和符号部分。我基本上是试图把OpenCV的包括在开始和结束。

• Clean up the project
• Rebuild, refresh, and all the other options in the "Index" submenu (when "right-clicking" on the project)
• Disable / enable the indexer in the preferences
• Verify that symbols such as trainIdx only appear in my OpenCV4Android include in the Paths and Symbols section.
• Change the order of my includes in the Paths and Symbols section. I basically tried to put the OpenCV include in the beginning and in the end.

我认为它是在 CDT指数因如下：

• 在命令行中，我可以通过建立我的项目 NDK-打造干净和 NDK建造。
• 当我启动Eclipse，我没有错误，直到我打开一个C ++文件（从 JNI 文件夹）。
• 我可以随时生成项目，但只要我打开了一个C ++文件，我不能，因为很多的现场运行应用程序了'＆LT;名称＆gt;无法得到解决。
• 如果我不打开C ++文件，Eclipse不报告任何错误，可以构建并成功地部署了Android应用程序。

• In command line, I can build my project using ndk-build clean and ndk-build.
• When I start Eclipse, I have no error until I open a C++ file (from the jni folder).
• I can always build the project, but as long as I have opened a C++ file, I can't run the application anymore because of a lot of Field '<name>' could not be resolved.
• If I don't open the C++ files, Eclipse doesn't report any error and can build and deploy the Android application successfully.

下面code报告了行， queryIdx ， PT <错误/ code>：

The following code reports errors on line, queryIdx, pt:

cv::line(mRgb, keypointsA[matches[i].queryIdx].pt, keypointsB[matches[i].trainIdx].pt, cv::Scalar(255, 0, 0, 255), 1, 8, 0);

如果我把它写如下，它的工作原理：

If I write it as follows, it works:

cv::DMatch tmpMatch = matches[i];
cv::KeyPoint queryKp = keypointsA[tmpMatch.queryIdx];
cv::KeyPoint trainKp = keypointsB[tmpMatch.trainIdx];
cv::line(mRgb, queryKp.pt, trainKp.pt, cv::Scalar(255, 0, 0, 255), 1, 8, 0);

这并不是说所有的OpenCV的功能没有得到解决：仅 PT ， queryIdx 和 trainIdx 是

任何意见将非常AP preciated。

Any comment will be really appreciated.

推荐答案

在您选定的项目$ P $在Eclipse环境中pferences，转到C / C ++通用 - > code分析 - >下水。确保两个复选框都没有选中。

In your selected project preferences within the Eclipse environment, go to C/C++ General -> Code Analysis -> Launching. Make sure that both check boxes are unchecked.
