(1)安装WSL;
(2)安装cmake:
wget https://github.com/Kitware/CMake/releases/download/v3.20.0/cmake-3.20.0-linux-x86_64.tar.gz
tar -xzvf cmake-3.20.0-linux-x86_64.tar.gz
sudo ln -sf $(pwd)/cmake-3.20.0-linux-x86_64/bin/* /usr/bin/
(3)安装gcc++:
# 如果 Ubuntu 版本 < 18.04,需要加入仓库
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc
sudo apt-get install g++
(4)安装GDB:
sudo apt install gdb
(5)clion建立空工程后选择toolchains如下:
依赖:
sudo apt install build-essential cmake git pkg-config libgtk-3-dev \
libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
libxvidcore-dev libx264-dev libjpeg-dev libpng-dev libtiff-dev \
gfortran openexr libatlas-base-dev python3-dev python3-numpy \
libtbb2 libtbb-dev libdc1394-22-dev libopenexr-dev \
libgstreamer-plugins-base1.0-dev libgstreamer1.0-dev
去github下载最新包:https://github.com/opencv/opencv.git
或者去官网下载 一个版本:https://opencv.org/releases/
cd opencv-4.x
mkdir -p build && cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE ..
make -j8
sudo make install
方法同opencv-4.x,但安装路径有区别,得注意。
不想编译也ok,直接:
sudo apt-get install -y libopencv-dev
