系统：jetson-nano-jp451-sd-card-image
ubuntu 18.04
（总共编译得2-3个多小时，大家耐心吧，时间相较于其它的已经很短了）
注意：！！make -j8以后千万别在动了，还有就是开始前把那些后台啥的都关掉，千万别在make -j8期间操作，要不然报错。
ps：如果你们编译其它的版本，我在这提供11个文件，你们得放到/opencv-contrib/modules/xfeatures2d/src/这个里面。
你们还得下载opencv和opencv-contrib的包，官网给你们放着，编译步骤参考我这个原理是一样的，得注意，他们两个的版本应该一样的。

1.下载源码，我提供的链接如下：
链接：https://pan.baidu.com/s/1QsrI67HmHXV59k6RetSMUQ?pwd=55d4
提取码：55d4
1.1文件上传的路径位置，注意ymck是我自己的用户名（你们自己换成你们自己相对应的就行）
2.解压文件
unzip opencv4.4.zip
3.安装依赖
#1.
pip install -i https://pypi.tuna.tsinghua.edu.cn/simple scikit-build==0.11.1
##注意，必须是这个版本，否则会报错，调试好久。。。#里面有些处理视频和图像的我就不在这单独说明了
#2.
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
#3.
sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
#4.
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
#5.
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
#6.
sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
#7.
sudo apt-get install cmake libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg-dev libpng-dev libtiff-dev libtiff5-dev libswscale-dev libcurl4-openssl-dev libtbb2 libdc1394-22-dev
4.增加swap交换内存
下面这个swap可以操作，也可以不操作，最好选一个吧。
4.1临时增加交换内存swap
sudo fallocate -l 4G /var/swapfile
sudo chmod 600 /var/swapfile #600是root权限，644是普通用户也行
sudo mkswap /var/swapfile
sudo swapon /var/swapfile
4.2永久增加swap
sudo fallocate -l 4G /var/swapfile
sudo chmod 600 /var/swapfile
sudo mkswap /var/swapfile
sudo swapon /var/swapfile
sudo bash -c 'echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab'
5.安装opencv4.4（里面是有contrib这个的）
5.1创建目录
#1.
cd opencv4.4/opencv-4.4.0/
#2.
mkdir build
#3.
cd build
5.2安装配置cmake选项
注意，里面ymck是我的用户名，大家自行修改，换成你们自己的！

..
大家可以看我的结果（如果buidl目录被玩坏了，可以新建一个其它的在进行cmake,我把这个结果放到最后面：）,大家往下看，一定这几个得出现，要不然弄了可能找不到opencv4.4，虽然不报错也能安装成功，但是你导入cv2，会报错，而且你也找不到这个包，
which python你们可以用这个代码查找相应的路径，一般和我这个路径差不多

5.3编译！！一定要增大swap否则会报错！！！！！
make -j8
5.3.1报错，一条cuda，一条内存不足，导致报错，所以大家一定要增大swap交换内存！！！！！！！！！！！，
5.3.2解决问题
增大swap，之前是1.9G，现在是5.9G，reboot以后即可恢复
现在未报错，可以看到swap的确跑到2.5G了，说明的确有点费swap
5.4开始安装
sudo make install
运行结果如下：
5.4.1waning解释，这是对开发者的一个警告，对咱们来说没啥问题我解释一下
CMake提醒开发者，它默认的FindCUDA模块已经被移除，会影响到之前依赖这个模块的构建脚本。这不会影响到项目的构建过程，只是作为一个提醒开发者进行代码维护的提示。
6.复制编译过程中的文件到自己在虚拟环境中的dist-packages,这样你就可以导入这个cv2了
这个python中的python3.9就是你编译过程中产生的
cp /usr/local/lib/python3.9/site-packages/cv2/python-3.9/cv2.cpython-39-aarch64-linux-gnu.so /home/ymck/archiconda3/envs/dc39/lib/python3.9/site-packages/
复制完成以后结果如下：
7.查看opencv版本
#1.
python
#2.
import cv2
#3.
print(cv2.__version__)
到这就说明大家成功编译完成啦，祝大家都成功呀！！！
8.安装过程
如下图：
大家可以看我的结果（如果buidl目录被玩坏了，可以新建一个其它的在进行cmake,我把这个结果放到最后面：
#这个是cmake以后的输出的结果：
# 大家可以自己对照一下，有些实在安装不上（java啥的，比较ubuntu18实在太老了。
#如果你们用的版本高，你们运行前面安装依赖的话，应该不会出现我下面这些no found。
#还有就是，一些warning，因为我升级了cmake版本，这些对咱们没啥影响，#warning不影响，那些warning是对开发者的一些提醒，遇见了不用在意。
