Eclipse CDT无效的项目路径 [英] Eclipse CDT Invalid Project Path

问题描述

我有一个使用makefile构建的C项目，Eclipse不断地警告无效的项目路径：重复的路径条目，但是我无法弄清楚它想要我做什么。我想禁用这个警告，并继续我的生活。

我的应用程序编译并运行正常，除了这个之外没有一个警告。作为一个认真的开发人员，我热衷于解决这个问题，所以我只有一个干净的构建可以带来温暖的模糊。

解决方案

使用Eclipse 3.7.2和CDT 8.0.2为我工作：

1. 打开项目属性| C / C ++ Build |发现选项。


2. 现在点击按钮清除发现的条目：。


3. 重建

它似乎是CDT 8中的一个新功能。我已经有这个无效的项目路径：重复的路径条目问题多年，这显然是新提供的解决方案。 p>

在这之前，C / C ++ General |下有重复的路径路径和符号|包含标签。我无法摆脱这些。只有当显示内置值被选中时，它们才会出现，因此它们显然是以某种方式生成的。做了这些以后，他们被替换了一个没有重复的集合。唯一的区别是在Assembly，GNU C和GNU C ++下都出现了相同的设置。以前他们是不同的套。例如，装配的是空的。

到目前为止，问题还没有返回。

I have a C project that is built using a makefile, Eclipse constantly warns about "Invalid project path: Duplicate path entries", but I cannot figure out what the hell it wants me to do. I would like to disable this warning and continue with my life.

My application compiles and runs fine, with not a single warning except this one. Being a conscientious developer I am keen to fix this problem so I have the warm fuzzies only a clean build can bring.

解决方案

This worked for me with Eclipse 3.7.2 and CDT 8.0.2:

1. Open the project properties | C/C++ Build | Discovery Options.
2. Click the button by Clear discovered entries now:.
3. Rebuild.

It is seems to be a new feature in CDT 8. I have had this "Invalid project path: Duplicate path entries" problem for years, and this is apparently the newly provided solution.

Before doing this there were duplicate paths under C/C++ General | Paths and Symbols | Includes tab. I could not get rid of these. They only appear when Show built-in values is checked, so they are apparently generated somehow. After doing the above they were replaced with a set that did not have duplicates. The only difference is that the same settings appeared under Assembly, GNU C, and GNU C++. Previously they were different sets. The ones for Assembly were empty, for example.

So far the problem has not returned.
