Question

我很难将Eclipse Juno配置为C / C ++。我是Windows用户，因此我在Eclipse下安装了Cygwin和MinGW以及CDT。还正确配置了PATH变量，尽管我在Eclipse C / C ++新项目中仍然没有任何新的工具链。

这些是我的Eclipse详细信息：

Eclipse Java EE IDE for Web Developers.

Version: Juno Release
Build id: 20120614-1722

另外，请参阅Eclipse的已安装组件的图像。 Installed components in Eclipse 从Windows命令行中包含一些outout：

我也熟悉Why doesn't MinGW show up in the list of Eclipse/Indigo CDT Toolchains?和How to deal with Eclipse CDT+Cygwin?以及http://wyding.blogspot.com/2009/04/setup-cygwin-toolchain-in-eclipse-cdt.html

有人能帮我意识到出了什么问题吗？

Answer 1

我有同样的问题。我找到了两种可能的解决方案：

当您选择“New Project-＆gt; C ++ Project-＆gt; Project Type：Executable”时，取消选中“仅当平台支持时显示项目类型和工具链”。
卸载“GNU Autotools”，然后您可以看到所需的选项。

Answer 2

根据CDT帮助页面：http://wiki.eclipse.org/CDT/User/FAQ#I_installed_MinGW_toolchain_on_my_PC_but_Eclipse_won.27t_find_it。

尽管你的PATH上有g ++。exe或gcc.exe并且定义了MINGW_HOME，你仍然可能得到一个“Toolchain”MinGW GCC“未检测到”消息（Luna 4.4.0上的CDT 8.4）。确保MINGW_HOME \ bin中存在名为“mingw32-gcc.exe”的文件。如果它不存在（使用MinGW-W64），请将-gcc.exe文件（例如i686-w64-mingw32-gcc.exe）复制到mingw32-gcc.exe。如果可怕的消息仍然存在，请重新启动系统（不要只注销并登录）。

Answer 3

我遇到了同样的问题。我通过将我的cygwin编译器程序的位置添加到PATH来修复它。 Maby你没有正确添加位置。对于cygwin，请将路径转到bin文件夹。

Answer 4

Eclipse试图找出cygwin1.dll的位置。但是这个文件在以前使用cygwin构建的许多程序中。所以Eclipse可以在安装正确的cygwin之前找到它。

所以一个可能的解决方案是将C：\ cygwin \ bin放在PATH变量的开头，所以Eclipse之前在那里搜索。

Answer 5

我无法让Eclipse（LUNA）在我的计算机上找到MinGW（首选项＆gt; C / C ++ /新C / C ++项目向导中没有MinGW可用），即使我已指定PATH在首选项＆gt; C / C ++ / Build＆gt;环境中为“C：\ MinGW \ bin”，所以我之后做的是：

创建一个简单的“Hello world”C项目，而不指定任何工具链
（在这一步我试图建立全部，但它失败了）
转到项目＆gt;属性，令人惊讶的是，在这里我可以看到MinGW GCC是Current工具链的可用选项。选择它。
现在我可以构建并运行项目

希望它有所帮助！

Eclipse CDT找不到Cygwin或MinGW工具链
