Ubuntu OpenCV安装和设置(Qt5？)

Question

新的Linux用户.操作系统:Ubuntu 14.04安装:OpenCV 2.4.9

我正在尝试安装OpenCV以用于代码块(或其他IDE).我已经跟随(或试图实际关注)以下页面上的每条指令:

我首先使用 https://help.ubuntu.com/community/OpenCV, 包括提供的脚本.

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/

我甚至看到将"Qt5Widgets"的安装前缀添加到CMAKE_PREFIX_PATH, 但我甚至不确定答案意味着什么,更不用说它是否有效,因为它显然没有用于问题OP.

这是在运行脚本时错误似乎从终端输出开始的地方:

经过先前的尝试,我在Home中有一个OpenCV文件夹,其zip文件和文件夹都名为opencv-2.4.9

所以"一些"事情已经完成,但没有完整的安装准备使用.也许更简单的解释一下

"""""""""""""""(引用早期问题的回答)这是记录在案的:http: //doc-snapshot.qt-project.org/qt5-stable/cmake-manual.html 最简单的方法使用CMake是将CMAKE_PREFIX_PATH环境变量设置为Qt的安装前缀5执行此导出CMAKE_PREFIX_PATH =/home/user/Programs /其中引用编译器等,以便此完整路径有效:/ home/user/Programs// bin/qmake """""""""""""""*

意思是完全解决这个问题.

谢谢.(仅供参考,我不能/不知道如何使用这个因为我没有程序文件夹,甚至用户文件夹,并且建议的终端命令会发出错误)

Answer 1

我能够通过使用来解决这个问题 sudo apt-get install qt5-default
