Ubuntu OpenCV安装和设置(Qt5?)

前端之家收集整理的这篇文章主要介绍了Ubuntu OpenCV安装和设置(Qt5?)前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
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).
我遵循(或尝试跟踪)实际上每一个在以下页面上的说明:

我第一次使用
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Add the installation prefix of “Qt5Widgets” to CMAKE_PREFIX_PATH
但我甚至不确定答案是什么意思,更不用说如果它会工作,因为它显然不是问题OP.

运行脚本时,这是错误出现在终端输出中的地方:

CMake Warning at cmake/OpenCVFindLibsGUI.cmake:18 (find_package):

之前的尝试,我有一个文件夹OpenCV在家里,一个zip文件文件夹都命名为opencv-2.4.9

所以“一些”的事情已经完成了,但没有一个完整的安装准备使用.也许是一个更简单的解释

“”“”“”“”“”“”(引自前面提到的答案)
这是记录在案:
http://doc-snapshot.qt-project.org/qt5-stable/cmake-manual.html
使用CMake的最简单的方法是设置CMAKE_PREFIX_PATH
环境变量为Qt 5的安装前缀
做这个
export CMAKE_PREFIX_PATH = / home / user / Programs /
其中引用了编译器等,以便这个完整的路径是有效的:
/ home / user中/程序//斌/ QMAKE
“” “” “” “” “” “” “”“*

意味着会解决这个问题.

谢谢. (FYI,我不能/不知道如何使用,因为我没有程序文件夹,甚至用户文件夹,建议的终端命令踢出一个错误)

我可以通过使用sudo apt-get install qt5-default来解决这个问题
