Ubuntu16.04下编译OpenCV3.4.0 + codeblocks

1.先安装一些支持包

[compiler] sudo apt-get install build-essential

[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

2.下载源码https://github.com/opencv/opencv/tree/3.4.0

cd ~/<my_working_directory>

git clone https://github.com/opencv/opencv.git

3.Building OpenCV from Source Using CMake

cd /opt/opencv

sudo mkdir build #新建一个名字为build的文件夹

cd build #切换到build文件夹

sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/opt/opencv .. #亲测，这里的/opt/opencv ..格式一定要对，此为opencv源码及cmake文件所在的地方

之后build：

make -j4 #run 4 jobs in parallel 并行运行4个工作

安装库：

sudo make install

之后我们用codeblocks IDE进行测试：以下用图片进行配置的展示：
