在 pkg-config 搜索路径中找不到 OpenCV 包

我已经按照中的说明安装了 OpenCVhttps://help.ubuntu.com/community/OpenCV 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，我收到此错误：

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？

好吧，我知道如何解决这个问题了......

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：

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

就是这样！现在一切都好。

该文件的内容是：

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

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以下位置下载安装脚本https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh并执行它。

从你的问题来看，我猜你正在使用Ubuntu（或衍生版本）。 如果您使用：

apt-file search opencv.pc

然后你会看到你必须安装libopencv-dev.

当你这样做之后，pkg-config --cflags opencv and pkg-config --libs opencv应该按预期工作。
