包OpenCV的不是在

我在https://help.ubuntu.com/community/OpenCV 包OpenCV的不是在

$ sudo su 
$ sudo apt-get install build-essential 
$ sudo apt-get install libavformat-dev 
$ sudo apt-get install ffmpeg 
$ sudo apt-get install libcv2.3 libcvaux2.3 libhighgui2.3 python-opencv opencv-doc libcv-dev libcvaux-dev libhighgui-dev

现在

安装使用说明书的OpenCV的pkg配置搜索路径发现当我执行“pkg配置--cfalgs --libs OpenCV的”我得到这个错误：

Package opencv was not found in the pkg-config search path. 
Perhaps you should add the directory containing `opencv.pc' 
to the PKG_CONFIG_PATH environment variable 
No package 'opencv' found

我该如何解决这个问题？

------- ------- UPDATE

OK，我想通了，如何解决这个问题？

我做了一个名为“OpenCV的文件。 PC “并复制到 ”在/ usr/local/lib目录/ pkgconfig“ 然后我说这两条线，以” .bashrc中“：

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig 
export PKG_CONFIG_PATH

这就是它！现在一切都好了。

文件的内容是：

prefix=/usr 
exec_prefix=${prefix} 
includedir=${prefix}/include 
libdir=${exec_prefix}/lib 

Name: opencv 
Description: The opencv library 
Version: 2.x.x 
Cflags: -I${includedir}/opencv -I${includedir}/opencv2 
Libs: -L${libdir} -lopencv_calib3d -lopencv_imgproc -lopencv_contrib -lopencv_legacy -lopencv_core -lopencv_ml -lopencv_features2d -lopencv_objdetect -lopencv_flann -lopencv_video -lopencv_highgui

UPDATE消息 - 2014年

看来，Ubuntu社区已完成对文档的安装OpenCV的，你现在要做的就是下载从https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh安装脚本并执行它。

林不知道，但我认为前缀是安装OpenCV的地方。我手动编译它，所以我要试试这个，但是在ubnuntu上更改前缀 – 2013-11-21 22:14:40

看来，Ubuntu社区已经完成了OpenCV的安装文档，

所以你现在要做的是从here下载安装脚本并执行它。

不要忘记使其可执行：

chmod +x opencv_latest.sh

然后

./opencv_latest.sh

你知道如何在使用脚本安装之后卸载opencv吗？以上？ – 2017-01-05 00:58:06

嗨，首先我希望你使用'新立得包管理器'。你只需要转到Ubuntu的软件中心，并寻找突触包管理器。它的优点是，你需要的所有软件包都可以在这里轻松获得。其次，它会自动配置您的所有路径。现在安装它，然后在那里搜索opencv软件包，如果您发现包含绿色框的软件包，然后安装它，否则软件包不在正确的位置，因此您需要重新安装它，但是这次是从软件包管理器重新安装。如果安装了，那么你可以做到这一点而已，你只需要填充的OpenCV的路径OpenCV_DIR变量（含OpenCVConfig.cmake文件）

export OpenCV_DIR=<path_of_opencv>

从你的问题我猜你是使用Ubuntu（或衍生物）。如果你使用：

apt-file search opencv.pc

然后你看，你必须安装libopencv-dev。

这样做后，pkg-config --cflags opencv和pkg-config --libs opencv应按预期工作。
