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
ot;spm":"1001.2101.3001.4334"}">

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
1

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
1

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：

其中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

2

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。
