之前在3399pro开发板上编译了opencv4.5.1的源码，将编译后的文件导出，在新的开发板上进行移植安装，本文记录了移植安装过程中出现的问题及解决方法。 (2021.05.18更新)
1、环境配置 在移植安装之前配置新板子的开发环境，参考博客 2、移植安装 进入到opencv的build 目录下进行安装cd ./buildmake install
正常情况下会安装成功，但我这边报了4个错；
错误1：No rule to make target '/lib/libjpeg.so', needed by 'lib/libopencv_imgcodecs.so.4.5.1'.解决办法：whereis libjpeg.so #找到libjpeg.so位置，我的是在/usr/lib/libjpeg.sosudo ln -s /usr/lib/libjpeg.so /lib/
继续make install
错误2：modules/videoio/CMakeFiles/opencv_videoio.dir/src/cap_gstreamer.cpp.o]解决办法：sudo aptitude install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
2021.05.18新增2个问题，在此记录一下
问题3：/home/syl/software/opencv/modules/python/src2/cv2.cpp:17:10: fatal error: Python.h: No such file or directory #include解决方法：sudo apt-get install python-devsudo apt-get install python3.7-dev
问题4：/home/syl/software/opencv/modules/python/src2/cv2.cpp:33:10: fatal error: numpy/ndarrayobject.h: No such file or directory #include解决方法： sudo apt-get install python-numpy
接着make install
安装成功！ 3、测试 安装完成后测试python-opencv播放摄像头正常，但通过c+±opencv播放摄像头报错如下：错误一：#执行命令g++ main.cpp -o c++-opencv `pkg-config --cflags --libs opencv`报错：Package opencv was not found in the pkg-config search path.Perhaps you should add the directory containing `opencv.pc'to the PKG_CONFIG_PATH environment variableNo package 'opencv' found解决方法：cd /usr/local/lib/pkgconfigsudo touch opencv.pc #拷贝同目录下opencv4.pc的内容export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
错误二：执行命令：./c++-opencv报错：main.cpp:2:10: fatal error: opencv2/opencv.hpp: No such file or directory #include解决方法：1、whereis libopencv_gapi.so.4.5 # libopencv_gapi.so.4: /usr/local/lib/libopencv_gapi.so.4.52、vim /etc/ld.so.conf.d/opencv.conf 写入/usr/local/lib/lib后保存3、ldconfig
