无法运行程序“g++”:启动失败 - Eclipse C++

Cannot run program “g++”: Launching failed - Eclipse C++

本文关键字：失败 启动 Eclipse C++ 运行 程序 g++      更新时间：2023-10-16

我必须用OpenCV做一些项目。我下载了Eclipse，用CDT升级了它，安装了MinGW并链接了OpenCV库。但是我仍然无法启动甚至单个程序！

有人可以告诉我，问题出在哪里吗？（我在Windows上工作）

各种答案的总结：

  1. 获取gcc-g++ bin和dll：请参考 MinGW 的 gcc-g++ 操作方法页面：http://www.mingw.org/wiki/InstallationHOWTOforMinGW

  2. 检查g++.exe位置并将其添加到环境变量中，PATH如有必要。

安装 MinGW

后，你仍然需要在 MinGW 中安装 gcc 和 g++ 编译器。
