在pkg-configsearchpath中找不到软件包opencv
我使用https://help.ubuntu.com/community/OpenCV中的说明安装了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 –cfalgs –libs opencv”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？

好，我想出了如何解决这个问题
我创build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=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH
而已！ 一切都好了。
该文件的内容是：
prefix=/usr exec_prefix=${prefix} includedir=${prefix}/include libdir=${exec_prefix}/lib Name: opencv Description: The opencv library Version: 2.xx 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社区已经完成了关于安装openCV的文档，现在你所要做的就是从https://github.com/jayrambhia/Install-OpenCV/blob/master/Ubuntu/opencv_latest.sh下载安装脚本并执行它。
从你的问题，我想你是使用Ubuntu（或派生）。 如果你使用：
apt-file search opencv.pc
那么你看到你必须安装libopencv-dev 。
在你这样做后， pkg-config --cflags opencv和pkg-config --libs opencv应该可以正常工作。
看来ubuntu社区已经完成了关于安装openCV的文档，
所以你现在要做的就是从这里下载安装脚本并执行它。
不要忘记让它可执行：
chmod +x opencv_latest.sh
然后
./opencv_latest.sh
嗨，首先，我希望你使用“新立得包pipe理器”。 你只需要到Ubuntu的软件中心，并寻找突触包pipe理器。这是美丽的是，所有你需要的软件包在这里很容易获得。 其次它会自动configuration你所有的path。 现在安装它，然后在那里searchopencv软件包，如果你find了绿色的软件包，然后安装它，否则软件包不在正确的地方，所以你需要重新安装它，但从包pipe理器这一次。 如果安装了，那么你只能这样做，你只需要用opencv的path填充OpenCV_DIRvariables（包含OpenCVConfig.cmake文件）
export OpenCV_DIR=<path_of_opencv>
