我试图通过在我的代码块中使用Kinect和openCV库来运行C++程序。一切似乎罚款期待我总是得到一个错误说：cv.h没有这样的文件或目录，但有这样的文件
/home/maoyi/Documents/practice/practice2.cpp:10:16: fatal error: cv.h: No such file or directory compilation terminated.
谁能告诉我，究竟是什么说没有这样的文件或目录有什么意思？因为我非常肯定我有一个practice2.cpp文件，我安装了46％的OpenCV库。我按照如何安装OpenCV2.1.0教程的说明：
http://www.samontab.com/web/2010/04/installing-opencv-2-1-in-ubuntu/
我在“CMAKE”遇到问题。步骤，并得到一些提示是这样的：
-- Detected version of GNU GCC: 46 (406) -- checking for module 'gstreamer-base-0.10' -- package 'gstreamer-base-0.10' not found -- checking for module 'gstreamer-app-0.10' -- package 'gstreamer-app-0.10' not found -- checking for module 'gstreamer-video-0.10' -- package 'gstreamer-video-0.10' not found -- checking for module 'libdc1394-2' -- package 'libdc1394-2' not found -- checking for module 'libdc1394' -- package 'libdc1394' not found -- checking for module 'libv4l1' -- package 'libv4l1' not found -- Could NOT find PythonLibs (missing: PYTHON_INCLUDE_DIRS) Traceback (most recent call last): File "", line 1, in ImportError: No module named numpy.distutils -- IPP detected: -- Parsing 'cvconfig.h.cmake'
而且我还试图打开我的立得软件包管理手动安装所有缺少的模块，但是我甚至找不到其中的一些。 （例如gstream-app-0.10）...所以我不知道这是否会导致“没有这样的文件或diretory”错误或什么。我对OpenCV很新，所以不要惊讶，如果问题很愚蠢。 但无论如何，我继续下一步“制造”的步骤，并得到更多的绝望的提示下面。安装停止在46％，我提到了大量的错误... 所以我希望有人可以看看它，也许可以暗示我一些解决方案。非常感谢！
