如何解决未解决的包含:在eclipse中?

I built a simple program in eclipse:

我在eclipse中构建了一个简单的程序:

#include <iostream>

using namespace std;
int main()
{
    cout << "TEST" << endl;
    return 0;
}

It worked in Visual Studio and CodeBlocks, but eclipse is acting weird. it says:

它在Visual Studio和CodeBlocks中工作，但是eclipse的表现却很奇怪。它说:

Unresolved inclusion: <iostream>

未包含:< iostream >

I read here: C++ - Unresolved inclusion: <iostream>

我在这里读到:c++ -未解析包含:

and here: Unresolved <iostream> in Eclipse, Ubuntu

这里是:在Eclipse中未解析的 ， Ubuntu

and neither of them worked.

他们俩都不工作。

Here are screenshots of project properties:

以下是项目属性的截图:

I downloaded MinGW and now i have this under Settings:

我下载了MinGW，现在我在下面设置:

How should i proceed? Maybe now i don't need #include <iostream> because it's now included in the project?

我该如何继续?也许现在我不需要#include ，因为它现在已经包含在项目中了?

I found iostream under Includes.

我发现iostream under include。

So i tried deleting #include <iostream>, but when i try to run the program i get: Launch Failed. Binary not found. error:

所以我尝试删除#include ，但是当我尝试运行程序时，我得到:Launch Failed。二进制文件没有找到。错误:

Thanks

谢谢

Seems like if i compile in some other program (say CodeBlocks) and create the exe file, then eclipse can run it. But it can't build its own exe.

似乎如果我在其他程序(比如代码库锁)中编译并创建exe文件，那么eclipse就可以运行它。但它不能建立自己的exe。

Why?

为什么?

This answer did not help me either. My issue was solved with the following steps:

这个答案对我也没有帮助。我的问题通过以下步骤得到解决:

You might try changing your source files from *.c to *.cpp. This will provoke gcc to think of the files as C++ and search the proper paths. Might need to make small modifications to the Makefile as well, like on the OBJ: line. Instead of:

您可以尝试从*修改源文件。c * . cpp。这将促使gcc将这些文件看作c++文件，并搜索适当的路径。可能还需要对Makefile进行小的修改，比如在OBJ: line上。而不是:

OBJS = YourFile.o

obj = YourFile.o

try

试一试

OBJS = YourFile.cpp

obj = YourFile.cpp

#2

right click your project click properties goto C/C++ Build > settings click on Misc. under GCC C++ Compiler and the other flags code should have this after it -std=c++11 then go to Misc. under GCC C Compiler and add this to the other flags code -std=gnu11 apply save your project build your project and it should work

右键单击您的项目，单击properties goto C/ c++ Build >设置，单击Misc。在GCC c++编译器和其他标记代码后面应该有这个-std=c++11，然后转到Misc。在GCC C编译器下，将它添加到其他标志代码-std=gnu11中，应用save您的项目构建您的项目，它应该可以工作
