1. Download OpenCV
Download address: Releases - OpenCV
Ubuntu select Sources version
2. Install dependencies
OpenCV dependencies
sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
安装gstreamer依赖文件
sudo apt-get -y install libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libgstreamer1.0-dev
if No package ‘gtk+-3.0‘ found
sudo apt install -y libgtk-3-devCMake compilation tool
sudo apt-get install cmake
sudo apt install cmake-qt-gui
sudo apt-get install libgtk2.0-dev
sudo apt-get install pkg-config3. Configure CMake to cross-compile OpenCV
Here we mainly refer to ubuntu environment installation opencv4_ubuntu installation opencv4_jbyyy, blog-CSDN blog
After clicking Configure, it may take a while to configure, about 10 minutes.
Configuration completed
world mode
build type
install path
pkg option
Click Configure again and wait about 3 minutes.
Finally click Generate, it will take about 3 minutes.
4. Compile OpenCV
In the build folder, execute the command
make -j4 && make installThis process takes about 10 minutes.
5. System configuration, environment variable configuration
5.1. Execute the following command to edit the file (create it if it does not exist):
sudo gedit /etc/ld.so.conf.d/opencv.conf5.2. Add the following content at the end of the opened opencv.conf file:
/home/wcx/opencv-4.6.0/build/install/lib(i.e. the prefix path + /lib just set)
Everyone’s address is different. Don’t just copy and paste it.
5.3. Execute configuration:
sudo ldconfig5.4. Execute the following command to edit the file (create it if it does not exist):
sudo gedit ~/.bashrcAdd the following content at the end of the opened bash.bashrc file:
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/home/wcx/opencv-4.6.0/build/install/lib/pkgconfig
export PKG_CONFIG_PATH(PKG_CONFIG_PATH=$PKG_CONFIG_PATH: the prefix path just set + /lib/pkgconfig)
Effective environment variables
source ~/.bashrc5.5. Now that the configuration is complete, exit the console, reopen it, and execute the command
pkg-config --modversion opencv4
Successful installation.
