统信UOS_arm64开发环境配置
统信UOS开发机器配置
一、配置ssh远程登陆并设置为开机自启动
(1)sudo vim /etc/ssh/sshd_config
修改以下三行
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes
(2)systemctl enable ssh
update-rc.d ssh enable 2 3 4 5
service sshd restart
二、安装开发环境所用的包
安装PyQt4
安装pyqt4–采用apt-get在线安装
sudo apt-get install libxext6 libxext-dev libqt4-dev libqt4-gui libqt4-sql # libqt4-gui不可用
sudo apt-get install qt4-dev-tools qt4-doc qt4-qtconfig qt4-demos qt4-designer
sudo apt-get install python-qt4
sudo apt-get install python-qt4-*
sudo apt-get install python-qscintilla2
# 下面四行表示python3，可以不用安装
sudo apt-get install python3-pyqt4
sudo apt-get install python3-pyqt4.qsci
sudo apt-get install python3-pyqt4.qtsql
sudo apt-get install python3-pyqt4.phonon
安装pip
cd ~
wget https://bootstrap.pypa.io/pip/2.7/get-pip.py
sudo python ./get-pip.py
pip install --upgrade setuptools
pip install --upgrade pip
安装程序所需py包
pip install twisted
sudo pip install pyinstaller==3.6 # 3.6版本可以打包py2程序
pip install pyyaml
pip install requests_toolbelt
pyinstaller用于py2的打包，因为要使用pyinstaller程序，不使用sudo安装则可执行文件放置在用户家目录/.local/bin下，还要修改环境变量，因此直接使用sudo安装，pyinstaller程序就安装到/usr/local/bin目录下。
安装opencv-python
有三种安装方式，分别是：
-
apt-get安装
sudo apt-get install python-opencv但安装后查看编译选项中GUI为GTK3，代码中调用cv2.namedWindow()会报错。
卸载:sudo apt-get remove python-opencv -
pip安装
# 查看pip中有哪些版本 gw1@gw1-PC:~$ pip install opencv-python== ERROR: Could not find a version that satisfies the requirement opencv-python== (from versions: 3.4.0.14, 3.4.10.37, 4.3.0.38) ERROR: No matching distribution found for opencv-python==仓库中只有三个版本from versions: 3.4.0.14, 3.4.10.37, 4.3.0.38，其中适用于py2的只有3.4.0.14
pip install opencv-python==3.4.0.14但是最后会报错导致安装失败，暂时还未找到原因。
-
源码安装
sudo apt-get install cmake g++ # 安装gtk2支持 sudo apt-get install libgtk2.0-dev # 安装gtk3支持 sudo apt-get install libgtk-3-dev使用opencv-3.4.1.zip源码包，放置到~/need_install/3opencv下
cd ~/need_install/3opencv unzip opencv-3.4.1.zip cd opencv-3.4.1 mkdir build cd build cmake -D WITH_GTK_2_X=ON ..这里我只加了
WITH_GTK_2_X=ON的编译选项，表示使用GTK2。
这里未指定安装位置，则采用默认位置安装，则会安装到系统如下目录：
/usr/local/bin
/usr/local/lib
/usr/local/share
后面的两个点表示上级目录，不能省略。cmake完成后，会出现如下结果：

GTK+: YES (ver 2.24.32)表示使用GTK2，Python 2的Interpreter、Libraries、numpy、packages path都有相应目录则表示成功找到python2，否则最后在python中import cv2会失败。make -j4 sudo make install
上述三种方式中，我采用了源码安装，安装完成后，可通过python -c "import cv2; print(cv2.getBuildInformation())"查看编译选项，通过如下验证python中是否可调用：
gw1@gw1-PC:~$ python
Python 2.7.16 (default, Feb 26 2021, 06:12:30)
[GCC 8.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'3.4.1'
安装视频捕获接口包
sudo apt-get install v4l-utils
三、关于卸载opencv-python
如果采用apt-get安装，卸载命令为sudo apt-get remove python-opencv
如果采用源码安装，则采用如下命令：
cd ~/need_install/3opencv/opencv-3.4.1/build
sudo make uninstall
sudo make clean
cd ..
sudo rm -r build
sudo rm -r
/usr/local/include/opencv2 \
/usr/local/include/opencv \
/usr/include/opencv \
/usr/include/opencv2 \
/usr/local/share/opencv \
/usr/local/share/OpenCV \
/usr/share/opencv \
/usr/share/OpenCV \
/usr/local/bin/opencv* \
/usr/local/lib/libopencv*
cd /usr/
find . -name "*opencv*" | xargs sudo rm -rf
统信终端机配置
终端机需要安装v4l-utils_1.16.3-3_arm64.deb包，其依赖包libv4l2rds0_1.16.3-3_arm64.deb也没有同样需要安装。
