在源代码编译mediapipe的时候，在编译安装opencv3.4.12时，遇到一些问题，记录下来。

1. opencv3.4.12 Install

# To have a full installation:
# $ cd <mediapipe root dir>
# $ sh ./setup_opencv.sh
#
# To only modify the mediapipe config for opencv:
# $ cd <mediapipe root dir>
# $ sh ./setup_opencv.sh config_only

set -e
if [ "$1" ] && [ "$1" != "config_only" ]
  then
    echo "Unknown input argument. Do you mean \"config_only\"?"
    exit 0
fi

opencv_build_file="$( cd "$(dirname "$0")" ; pwd -P )"/third_party/opencv_linux.BUILD
echo $opencv_build_file

workspace_file="$( cd "$(dirname "$0")" ; pwd -P )"/WORKSPACE
echo $workspace_file
if [ -z "$1" ]
  then
    echo "Installing OpenCV from source"
    sudo apt update && sudo apt install build-essential git
    sudo apt install cmake ffmpeg libavformat-dev libdc1394-22-dev libgtk2.0-dev \
                     libjpeg-dev libpng-dev libswscale-dev libtbb2 libtbb-dev \

    #rm -rf /tmp/build_opencv

    cd /tmp/build_opencv
    #git clone https://github.com/opencv/opencv_contrib.git
    #git clone https://github.com/opencv/opencv.git
    mkdir opencv-3.4.12/release
    #cd opencv_contrib

fi

~/opencv_contrib/modules/xfeatures2d/src/boostdesc.cpp:673:20: fatal error: boostdesc_bgm.i: No such file or directory

解决方法：

查看 build 文件夹下的日志文件 CMakeDownloadLog.txt，在日志文件CMakeDownloadLog.txt中搜索 boostdesc_bgm.i 关键词。日志文件里就有它的下载地址，到指定位置下载即可。https://github.com/opencv/opencv_contrib/issues/1301，点开上面这个网址往下拉，有人提供了缺失的各个文件的链接，点击保存. 或者直接在这个网页里搜索 BenbenIO 这个用户的回答。

或者到本文提供的下载镜像去下载：boostdesc_bgm.i,vgg_generated_48.i等.rar

下载后，直接拷贝源码并生存同名文件，放在 opencv_contrib/modules/xfeatures2d/src/ 路径下即可。

对于opencv2/xfeatures2d/cuda.hpp: No such file or directory 类问题的解决方法 改为绝对目录


/usr/local/arm/opencv-3.4.0/opencv_contrib-3.4.0/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp:42:10: 
fatal error: /opencv2/xfeatures2d.hpp: No such file or directory
 #include "/opencv2/xfeatures2d.hpp"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

40 #ifndef __OPENCV_XFEATURES2D_HPP__
41 #define __OPENCV_XFEATURES2D_HPP__
 
42#include"/usr/local/arm/opencv3.4.0/opencv_contrib3.4.0/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp"

2. 测试

安装测试代码；

#include "opencv2/core.hpp"
#include "opencv2/imgproc.hpp"
#include "opencv2/highgui.hpp"
#include <iostream>
using namespace cv;
using namespace std;
int main()
{
    cout << "Hello OpenCV " << CV_VERSION << endl;
    Mat myMat = imread("timg.jpeg", 1);
    namedWindow("Opencv Image", WINDOW_AUTOSIZE);
    imshow("Opencv Image", myMat);
    waitKey(5000);
    return 0;
}

方式一： g++ test.cpp pkg-config --libs --cflags opencv -o opencv
方式二： cmakelist.txt

cmake_minimum_required(VERSION 2.8)
project(opencv)
find_package(OpenCV REQUIRED)
add_executable(opencv opencv.cpp)
target_link_libraries(opencv ${OpenCV_LIBS})
