makefile for opencv

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：

这一版也可以：

注意：如果报错：Makefile:1: *** missing separator.  Stop.

原因：

makefile里不要乱用TAB，命令所在行才能且只能以TAB开头

其他的如，make变量的定义、赋值，make内定函数如$(error "strings")都不能以TAB开头，不然make会将其作为命令来处理
