### 代码下载编译安装 ###

$ git clone https://github.com/opencv/opencv.git
    $ cd opencv
    $ mkdir build
    $ cd build
    $ cmake ..
    $ make
    $ sudo make install

### 编译后demo运行出错 ###

> terminate called after throwing an instance of 'cv::Exception'
      what():  OpenCV(4.4.0-dev) /home/hui/data/study/opencv/modules/highgui/src/window.cpp:634: error: (-2:Unspecified error) 
      The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. 
      If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvNamedWindow'

#### 解决办法 ####

> cmake选项中加上：WITH\_GTK=ON

> sudo apt install libgtkglext1-dev

#### cmake后的输出 ####

> cmake选项中加上：BUILD\_TIFF=ON

最后的cmake配置项如下

cmake -D CMAKE_BUILD_TYPE=RELEASE \
     -D CMAKE_INSTALL_PREFIX=/usr/local \
     -D INSTALL_PYTHON_EXAMPLES=ON \
     -D INSTALL_C_EXAMPLES=ON \
     -D WITH_GTK=ON \
     -D BUILD_TIFF=ON ..

### build后还是报错 ###

> 找到opencv的库，看了下make install没有更新，然后删除掉/usr/local/lib下的opencv相关库后重新make install

$ cd /usr/local/lib
    $ ls -l libopencv_core.so.4.4.0
    -rw-r--r-- 1 root root 18073456 8月  31  2020 libopencv_core.so.4.4.0
    $ rm libpencv*

> 在demo中cmake后，OpenCV version变成4.5.3，成功了!

$ cmake ..

使用demo是Learn-OpenCV-4，openCV 4计算机视觉项目实战一本书的例子：

> https://github.com/PacktPublishing/Learn-OpenCV-4-By-Building-Projects-Second-Edition.git

在opencv的目录下也有sample：

> opencv/samples/cpp/tutorial\_code/

sample对应的图片资源需要单独下载

> https://github.com/opencv/opencv\_extra.git

比如使用seamless\_cloning的sample代码, copy 前面demo的一个CMakeLists.txt改改就可以用。

$ cd opencv/samples/cpp/tutorial_code/photo/seamless_cloning
    $ mkdir build
    $ cmake ..
    $ make

生成clone-demo，然后copy opencv\_extra对应的资源目录到buld下, 就可以运行sample-demo了。

$ cp -rf opencv_extra/testdata/cv/cloning opencv/samples/cpp/tutorial_code/photo/seamless_cloning/build/.
