c++ - 无法运行程序 “g++” : Launching failed - Eclipse C++

Question

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单个程序!

谁能告诉我，问题出在哪里？ (我在 Windows 上工作)

Answer 1

各种答案总结:

1. 获取gcc-g++ bin和dll: gcc-g++请引用MinGW how to page: http://www.mingw.org/wiki/InstallationHOWTOforMinGW

2. 检查 g++.exe 位置并在必要时将其添加到您的环境变量 PATH 中。
