程序无法启动，因为 Eclipse CDT 中缺少 cygwin1.dll...
我的计算机上安装 Eclipse for Java 已有几年了，决定安装 CDT 并学习 C。我安装了 MinGW 和 Cygwin，CDT 检测到并当我做一个新项目时尝试使用它们。
我选择文件>新建 C++ 项目，然后选择 Hello World C++ 项目 和 CygwinGCC 工具链。我将项目命名为“asdf”并点击工具栏中的“Build Debug”。编译器完成，没有错误。我点击“运行”，但什么也没发生。
手动浏览到项目目录并运行 asdf.exe 会出现错误：“程序无法启动，因为您的计算机中缺少 cygwin1.dll。请尝试重新安装程序来解决此问题。”
使用 MinGW 也会发生同样的情况，只是缺少不同的 dll。
我需要做什么才能获得可用的 .exe？
（我正在运行 Windows 7 x64 以及最新版本的 Eclipse 和 CDT。）
编辑： 编译器输出如下：
**** Build of configuration Debug for project asdf ****

I've had Eclipse for Java on my computer for a few years, and decided to install the CDT and learn C. I installed both MinGW and Cygwin and the CDT detects and tries to use them when I make a new project.
I choose File > New C++ Project and choose Hello World C++ Project and the CygwinGCC toolchain. I name the project "asdf" and hit "Build Debug" in the toolbar. The compiler completes without error. I hit Run and nothing happens.
Browsing to the project directory manually and running asdf.exe gives me an error saying:"The program can't start because cygwin1.dll is missing from your computer. Try reinstalling the program to fix this problem."
The same thing happens using MinGW, only a different dll is missing.
What do I need to do to have a usable .exe?
(I'm running Windows 7 x64 and the newest version of Eclipse and the CDT.)
EDIT:
The compiler output is as follows:

此错误消息意味着 Windows 无法找到“cygwin1.dll”。 Cygwin gcc 创建的程序依赖于此 DLL。该文件是 cygwin 的一部分，因此很可能位于 C:\cygwin\bin 中。要解决此问题，您只需将 C:\cygwin\bin （或可以找到 cygwin1.dll 的位置）添加到系统路径中。或者，您可以将 cygwin1.dll 复制到 Windows 目录中。
有一个名为 DependencyWalker 的好工具，您可以从 http://www.dependencywalker.com< 下载/a> .您可以使用它来检查可执行文件的依赖关系，因此，如果您检查生成的程序，它会告诉您哪些依赖关系丢失以及哪些依赖关系已解决。
This error message means that Windows isn't able to find "cygwin1.dll". The Programs that the Cygwin gcc create depend on this DLL. The file is part of cygwin , so most likely it's located in C:\cygwin\bin. To fix the problem all you have to do is add C:\cygwin\bin (or the location where cygwin1.dll can be found) to your system path. Alternatively you can copy cygwin1.dll into your Windows directory.
There is a nice tool called DependencyWalker that you can download from http://www.dependencywalker.com . You can use it to check dependencies of executables, so if you inspect your generated program it tells you which dependencies are missing and which are resolved.
您可以使用 Cygwin 的
g++或 MinGW 进行编译（通过独立或使用 Cygwin 软件包）。但是，为了运行它，您需要将Cygwin1.dll（和其他）路径添加到系统 Windows 路径中，位于任何 cygwin 样式路径之前。因此，将
;C:\cygwin64\bin添加到 Windows 系统PATH<的末尾 /代码> 变量。此外，要编译以在 CMD 或 PowerShell 中使用，您可能需要使用：
（这会调用交叉编译器，如果已安装。）
You can compile with either Cygwin's
g++or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add theCygwin1.dll(and others) PATH to the system Windows PATH, before any cygwin style paths.Thus add:
;C:\cygwin64\binto the end of your Windows systemPATHvariable.Also, to compile for use in CMD or PowerShell, you may need to use:
(This invokes the cross-compiler, if installed.)
要添加到此并保存某人另一个谷歌，只需在 cmd 中执行以下操作：
