在 Eclipse 上安装 OpenCV for Android 的问题：各种错误，包括"在 PATH 中找不到"

我试图在Eclipse (Windows 8)上安装OpenCV for Android .我遵循了以下三个教程:http://www.youtube.com/watch?v=N2onPuDZQVY一步一步地找到，但当我试图构建任何示例项目时仍然会遇到错误。这些是我在控制台中得到的错误:

我在"问题"选项卡中看到了这个:

我哪里错了?我的C/c++构建命令是:${NDKROOT}ndk-build。cmd和我有环境变量正确定义与包含ndk-build的文件夹的完整路径。cmd文件。如果还有其他需要我提供的信息，请告诉我。任何帮助将是非常感激的-这已经打败了我整整一个星期了!
