如何配置Makefile以使用OpenCV

How to configure Makefile to use OpenCV

本文关键字：OpenCV Makefile 何配置 配置      更新时间：2023-10-16

我在RaspberryPi中安装了opencv并配置了Makefile，但它找不到头文件。如何正确配置Makefile？

我有两个.cpp文件和一个.h文件。

BlobLabeling.cpp  BlobLabeling.h  hand_tracking.cpp

当我运行make时，它返回以下内容：

pi@raspberrypi ~/test $ make
g++ BlobLabeling.cpp
In file included from BlobLabeling.cpp:2:0:
BlobLabeling.h:9:31: fatal error: highgui/highgui.hpp: No such file or directory
compilation terminated.
Makefile:11: recipe for target 'BlobLabeling.o' failed
make: *** [BlobLabeling.o] Error 1

在Blob标签.cpp中

#include "BlobLabeling.h"

在hand_track.cpp中

#include <stdio.h>
#include "cv.h"
#include "highgui.h"
#include "BlobLabeling.h"

在Blob标签中。h

#include "highgui/highgui.hpp"
#include "opencv.hpp"

生成文件

CXX = g++
LDFLAGS = -lopencv_legacy -lopencv_highgui -lopencv_core -lopencv_ml -lopencv_video -lopencv_imgproc -lopencv_calib3d -lopencv_objdetect -L/usr/lib
CPPFLAGS = -g -I/usr/include/opencv -I/usr/include/opencv2
all: BlobLabeling.o hand_tracking.o
        g++ -o test BlobLabeling.o hand_tracking.o
BlobLabeling.o: BlobLabeling.cpp
        g++ BlobLabeling.cpp
hand_tracking.o: hand_tracking.cpp BlobLabeling.h
        g++ hand_tracking.cpp

在/usr/include/opencv2中

pi@raspberrypi ~/test $ ls /usr/include/opencv2
calib3d  features2d  imgproc  objdetect   stitching  videostab
contrib  flann       legacy   opencv.hpp  ts
core     highgui     ml       photo       video

请使用正确的c++标头：

#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"

连同包含路径：

-I/usr/include/opencv2

而不是过时的"cv.h"answers"highgui.h"
