本文介绍了一个使用OpenCV在Linux环境下加载并显示图片的基本程序实例，包括了必要的编译指令及Makefile配置，确保了不同版本间的兼容性。

test2.cpp:

#include <stdio.h>
#include <opencv2/core/core.hpp>.h>
#include <opencv2/highgui.hpp>
int main()
{
        IplImage * image=NULL;
        image = cvLoadImage("lena.jpg");
        if( !image )
                printf("loading error!\n");
        else
        {
                cvNamedWindow("1");
                cvShowImage("1", image);
                cvWaitKey(0);
                cvDestroyWindow("1");
        }
        return 0;
}

makefile:

CXXFLAGS:= $(shell pkg-config --cflags opencv)

LDLIBS:= $(shell pkg-config --libs opencv)

OBJS:= test2.o

all:test2

test2:$(OBJS)

g++ -o test2 $+ $(CXXFLAGS) $(LDLIBS)

%.o:%.cpp

g++ -c $+ $(CXXFLAGS)

clean:

rm -f *.o

这个自己测试的编译成功

2.4与3.0混版g++ok：

g++ -I/usr/include -I/usr/include/opencv -I/usr/include/opencv2 -o"MoveSense_Dvpu" test2.cpp /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgcodecs.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_shape.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_superres.so /usr/local/lib/libopencv_videoio.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so

这个也ok：

INCLUDES = -I /usr/local/include
LIBS +=-lm -lstdc++ -L /usr/local/lib/libopencv_calib3d.so \
/usr/local/lib/libopencv_core.so\
/usr/local/lib/libopencv_features2d.so \
/usr/local/lib/libopencv_flann.so \
/usr/local/lib/libopencv_highgui.so \
/usr/local/lib/libopencv_imgcodecs.so \
/usr/local/lib/libopencv_imgproc.so \
/usr/local/lib/libopencv_ml.so \
/usr/local/lib/libopencv_objdetect.so \
/usr/local/lib/libopencv_photo.so \
/usr/local/lib/libopencv_shape.so \
/usr/local/lib/libopencv_stitching.so \
/usr/local/lib/libopencv_superres.so \
/usr/local/lib/libopencv_videoio.so \
/usr/local/lib/libopencv_video.so \
/usr/local/lib/libopencv_videostab.so

OBJS:= test2.o
#OBJS:= ./main/main_dsst.o
all:test2
test2:$(OBJS)
        g++ -o test2 $+ $(LIBS) $(INCLUDES)
%.o:%.cpp
        g++ -c $+ $(INCLUDES)
clean: 
        rm -f *.o test2

这一版也可以：

#这里需要根据自己在linux上配置的opencv路径修改  
INCLUDES = -I /usr/local/include
LIBS +=-lm -lstdc++ -L/usr/local/lib/libopencv_calib3d.so \

# LIBS = -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml  
#  LIBDIRS = -L/usr/local/lib  
    OPT = -O3 -Wno-deprecated
      
    CC=g++  
      
    .PHONY: all clean  
      
    OBJS= test2.o
      
    clean:  
        rm -f *.o *~ test2  
      
    all:test2  
        echo all:make complete  
      
    test2:$(OBJS)
        #$(CC) $(LIBDIRS) $(LIBS) -o $@ $+ $(OPT)
        $(CC) $(OPT) $(INCLUDES) $+ $(LIBS) -o $@
        #$@代表冒号后面的依赖项 $+代表冒号前面的目标，目标一定要放在libs的前面
    
    %.o:%.cpp
        $(CC) -c $(INCLUDES) $+
