opencv qt5安装linux,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:
这是运行脚本时错误出现在终端输出中的位置:
CMake Warning at cmake/OpenCVFindLibsGUI.cmake:18 (find_package):

"Qt5Core" provides a separate development package or SDK, be sure it has
been installed.

See also "/home/*******/OpenCV/opencv-2.4.9/build/CMakeFiles/CMakeError.log".
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
