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

问题描述

我已按照 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，出现此错误:

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?

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

好的，我想出了解决问题的方法...

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！一切都很好.

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

看来，ubuntu社区已经完成了有关安装openCV的文档，您现在要做的就是从

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.
