在 pkg-config 搜索路径中找不到包 opencv [英] Package opencv was not found in the pkg-config search path

问题描述

我已经按照 https://help.ubuntu.com/community/OpenCV<中的说明安装了 OpenCV/a>

I have installed OpenCV using the instructions in https://help.ubuntu.com/community/OpenCV

$ 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

现在当我执行pkg-config --cflags --libs opencv"时出现这个错误:

now when i execute "pkg-config --cflags --libs opencv" i get this error:

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?

how can I resolve this problem?

-------更新-------

好的，我想出了如何解决这个问题...

OK, I figured out how to solve the problem...

我制作了一个名为opencv.pc"的文件并将其复制到/usr/local/lib/pkgconfig"然后我将这两行添加到.bashrc"中:

I made a file named "opencv.pc" and copied it to "/usr/local/lib/pkgconfig" Then i added these two lines to ".bashrc":

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

就是这样！现在一切正常.

that's it! everything is OK now.

文件内容为:

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

看来ubuntu社区已经完成了安装openCV的文档，你现在要做的就是从https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh 并执行它.

it seems that the ubuntu community has completed the documentation on installing openCV, all you have to do now is to download the installation script from https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh and execute it.

推荐答案

貌似ubuntu社区已经完成了安装openCV的文档，

it seems that the ubuntu community has completed the documentation on installing openCV,

所以你现在要做的就是从 此处 并执行它.

so all you have to do now is to download the installation script from here and execute it.

不要忘记让它可执行:

chmod +x opencv_latest.sh

然后

./opencv_latest.sh
