Ubuntu OpenCV安装和设置(Qt5吗？)

问题描述

新的Linux用户。操作系统：Ubuntu 14.04 Install：OpenCV 2.4.9

我正在尝试安装OpenCV以便在代码块(或其他IDE)上使用。我已经遵循(或实际上试图遵循)以下页面上的每条指令：

我首先使用了包括所提供脚本的https://help.ubuntu.com/community/OpenCV。

然后http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html

最后http://www.samontab.com/web/2012/06/installing-opencv-2-4-1-ubuntu-12-04-lts/

我什至看到了Add the installation prefix of “Qt5Widgets” to CMAKE_PREFIX_PATH，但我什至不确定答案的含义，更let论它是否有效，因为它显然不适用于“问题OP”。

这是运行脚本时错误出现在终端输出中的位置：

经过先前的尝试，我在Home内有了一个OpenCV文件夹，其中有一个zip文件和名为opencv-2.4.9的文件夹。

这样就完成了”some”的事情，但是还没有完整的安装可供使用。也许是什么更简单的解释

“””””””””””””(引用先前问题的答案)：http://doc-snapshot.qt-project.org/qt5-stable/cmake-manual.html使用CMake的最简单方法是将CMAKE_PREFIX_PATH环境变量设置为Qt 5的安装前缀。执行此操作导出CMAKE_PREFIX_PATH = /home /user /Programs /，其中引用了编译器等。，以便此完整路径有效：/home /user /Programs //bin /qmake “”””””””””””””” *

就是完全可以解决这个问题。

谢谢。 (仅供参考，我可以’t/don’t知道如何使用它，因为我没有程序文件夹，甚至没有用户文件夹，建议的终端命令也将引发错误)

最佳回答

我可以使用sudo apt-get install qt5-default解决此问题
