无法运行程序“g ++”:启动失败 – Eclipse C ++

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。 但是我还是无法启动单个程序!

有人可以告诉我,问题在哪里? (我在Windows上工作)

各种答案摘要:

  1. 获取gcc-g++ bindll :请参考MinGW的gcc-g ++页面: http : //www.mingw.org/wiki/InstallationHOWTOforMinGW

  2. 检查g++.exe位置,并将其添加到您的环境变量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。
