Eclipse CDT : running C++ program not showing anything in the console! Why?
提问by Phil
I'm running the latest version of Eclipse with CDT on Windows 64 bits with Cygwin for compiling the code.
我正在使用 Cygwin 在 Windows 64 位上使用 CDT 运行最新版本的 Eclipse 以编译代码。
My problem is that when i run any c++ software in eclipse, there is no output in the console.
我的问题是，当我在 eclipse 中运行任何 c++ 软件时，控制台中没有输出。
I have tried this:
我试过这个：
Eclipse CDT debugger does not show console
and this:
和这个：
Eclipse CDT Debug console not displaying program output
But it does not works.
但它不起作用。

As guys at "No Console Output (MinGW, CDT)"point out, this is probably (or at least sometimes) because Eclipse does not add PATHto MINGW\binwhen launching the executable, so:
由于人在“无控制台输出（MinGW的，CDT）”指出，这可能是（或有时至少），因为Eclipse不添加PATH到MINGW\bin启动可执行文件时，那么：
In the "Environment" tag, press "New", set it as:
在“环境”标签中，按“新建”，将其设置为：
- "Name:PATH"
- "Value:C:\MinGW\bin"
- “名称：路径”
- “值：C:\MinGW\bin”
;)

If All above is not working then You can try this
如果以上都不起作用，那么你可以试试这个
You have to add Environment variable of this project to have the path of MinGW compiler
你必须添加这个项目的环境变量才能有MinGW编译器的路径
Goto Project->Properties->Run/Debug Settings, choose the .exe file and press Edit In the Environment tag, press New, and set it as: Name: PATH Value: C:\MinGW\bin
If you are using cygwin then Value: c:\cygwin\bin
转到 Project->Properties->Run/Debug Settings，选择 .exe 文件并按 Edit 在 Environment 标签中，按 New，并将其设置为： Name: PATH Value: C:\MinGW\bin
如果您使用的是 cygwin，则值：c:\cygwin\bin

Make sure the console is allocated:
确保控制台已分配：
project properties --> Run/Debug Settings --> yours.exe --> edit --> Common --> Check 'Allocate Console'
项目属性 --> 运行/调试设置 --> yours.exe --> 编辑 --> 通用 --> 选中“分配控制台”

Thanks for the answers. I have found the problem. It was a bug from Eclipse.
感谢您的回答。我找到了问题所在。这是来自 Eclipse 的错误。
I went in the Help > Check For Updates.

I installed an update and now it works!
我安装了一个更新，现在它可以工作了！

I faced this issue not long ago. Follow this linkwhich provides quite a detailed tutorial on how to setup everything. However, the console on Eclipse Mars CDT still did not show anything. After running the generated executable file from the command line i faced the following error:
不久前我遇到了这个问题。按照此链接提供有关如何设置所有内容的详细教程。但是，Eclipse Mars CDT 上的控制台仍然没有显示任何内容。从命令行运行生成的可执行文件后，我遇到以下错误：
So considering the missing path I searched for it on cygwin main folder and added to the Project Properties -> C/C++ General -> Paths and Symbols -> Includes GNU C++the path to the missing dll folder: ${CYGWIN_HOME}/usr/i686-pc-cygwin/sys-root/usr/bin.
Run again the project, and the problem was solved:
因此，考虑到丢失的路径，我在 cygwin 主文件夹中搜索了它并添加到项目属性 -> C/C++ 常规 -> 路径和符号 -> 包含 GNU C++丢失的 dll 文件夹的路径：${CYGWIN_HOME}/usr/i686-pc-cygwin/sys-root/usr/bin. 再次运行项目，问题解决：
I hope this will help somebody!
我希望这会帮助某人！

As Singhakanswered, this issue can be "fixed" on a project-by-project basis by adding a PATH environment variable to the project's Launch configuration: Project > Properties > Run/Debug Settings > (select the project executable) > Edit.. > Environment > New... (Name: PATH, Value: path/to/compiler/bin). But you'll have to do that for every project - I don't think there's a way to set it up to work for every project, at least I have not been able to.
正如Singhak 所回答的那样，可以通过将 PATH 环境变量添加到项目的启动配置中来逐个项目地“修复”此问题：项目 > 属性 > 运行/调试设置 >（选择项目可执行文件）> 编辑.. > 环境 > 新建...（名称：PATH，值：path/to/compiler/bin）。但是您必须为每个项目都这样做 - 我认为没有办法将其设置为适用于每个项目，至少我无法做到。
However, if you're running Windows and have MS Visual Studio installed, you can set the project up using Microsoft Visual C++ Toolchains instead of GCC and that should work as expected every time.
但是，如果您运行的是 Windows 并安装了 MS Visual Studio，则可以使用 Microsoft Visual C++ 工具链而不是 GCC 来设置项目，并且每次都应该按预期工作。

I think this night be connected to the order in which I installed MinGW and eclipse CDT (Helios). The solution (for me) was to go Project -> Properties -> C/C++ Build -> Settings -> Tool Settings -> MinGW C++ Linker -> Miscellaneous -> and set Linker flags to -static-libgcc -static-libstdc++. But I seem to need to do this for every project so I'm still searching for a permanent fix.
我认为今晚与我安装 MinGW 和 eclipse CDT (Helios) 的顺序有关。解决方案（对我来说）是去项目 -> 属性 -> C/C++ 构建 -> 设置 -> 工具设置 -> MinGW C++ 链接器 -> 杂项 -> 并将链接器标志设置为 -static-libgcc -static-libstdc++。但我似乎需要为每个项目都这样做，所以我仍在寻找永久修复。
