树莓派4B安装opencv

设备

1. 树莓派4B(4GB)
2. 闪迪16GB Micro SD
3. Linux raspberrypi 4.19.75-v7l+
4. opencv-3.4.3
5. opencv_contrib-3.4.3

fatal error: opencv2/xfeatures2d/cuda.hpp: 没有那个文件或目录

完整内容

/home/pi/Folder/opencv-3.4.3/modules/stitching/include/opencv2/stitching/detail/matchers.hpp:52:12: fatal error: opencv2/xfeatures2d/cuda.hpp: 没有那个文件或目录
 #  include "opencv2/xfeatures2d/cuda.hpp"
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

路径：

/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/src


解决办法：

打开对应文件，把相对路径改成绝对路径

错误1

vim /home/pi/Folder/opencv-3.4.3/modules/stitching/include/opencv2/stitching/detail/matchers.hpp

替换后的绝对路径

#include "/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d/cuda.hpp"

错误2

vim /home/pi/Folder/opencv-3.4.3/modules/stitching/src/precomp.hpp

替换内容同上

fatal error: boostdesc_bgm.i: 没有那个文件或目录

路径：

/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/src/boostdesc.cpp:653:20:


解决办法：

下载对应文件，移动到

/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/src

目录下

备注

实际缺少多个文件

fatal error: opencv2/xfeatures2d.hpp: 没有那个文件或目录

完整报错

/home/pi/Folder/opencv-3.4.3/modules/stitching/src/matchers.cpp:52:10: fatal error: opencv2/xfeatures2d.hpp: 没有那个文件或目录
 #include "opencv2/xfeatures2d.hpp"
          ^~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

打开对应文件

vim /home/pi/Folder/opencv-3.4.3/modules/stitching/src/matchers.cpp

把相对路径换为绝对路径

#include "/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp"

fatal error: opencv2/xfeatures2d/nonfree.hpp: 没有那个文件或目录

完整报错

/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp:43:10: fatal error: opencv2/xfeatures2d/nonfree.hpp: 没有那个文件或目录
 #include "opencv2/xfeatures2d/nonfree.hpp"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

解决办法

打开文件

vim /home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d.hpp

修改路径

#include "/home/pi/Folder/opencv_contrib-3.4.3/modules/xfeatures2d/include/opencv2/xfeatures2d/nonfree.hpp"

cp: 无法创建普通文件’/usr/local/lib/pkgconfig/opencv.pc’: 没有那个文件或目录

命令

cp /home/pi/Folder/opencv-3.4.3/build/lib/pkgconfig/opencv.pc /usr/local/lib/pkgconfig/opencv.pc

解决方案

自行创建了

/usr/local/lib/pkgconfig/


也不知道是对是错

g++: error: pkg-config –cflags –libs opencv3: 没有那个文件或目录

命令

g++ -ggdb 'pkg-config --cflags --libs opencv3' opencv_version.cpp  -o /tmp/opencv_version && /tmp/opencv_version

解决办法：

把单引号改成倒引号

g++ -ggdb `pkg-config --cflags --libs opencv3` opencv_version.cpp  -o /tmp/opencv_version && /tmp/opencv_version

Package opencv3 was not found in the pkg-config search path.

完整描述

Package opencv3 was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv3.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv3' found
/usr/bin/ld: /tmp/ccYDmS9g.o: in function `main':
。。。

解决方法

pkg-config中opencv.pc复制后要改为opencv3.pc

mv /usr/local/lib/pkgconfig/opencv.pc  /usr/local/lib/pkgconfig/opencv3.pc

/usr/bin/ld: warning: libopencv_core.so.3.4, needed by /home/pi/Folder/opencv-3.4.3/build/lib/libopencv_stitching.so, not found (try using -rpath or -rpath-link)

命令

g++ -ggdb `pkg-config --cflags --libs opencv3` opencv_version.cpp  -o /tmp/opencv_version && /tmp/opencv_version

不知道哪个缺德的给的解决办法，千万不要试

apt-get autoremove libopencv-dev

卸载了一堆库，然后我就放弃了

软件包 libopencv-dev 未安装，所以不会被卸载

很明星，我删库了。

删库跑路，江湖再会。
