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：

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 \
/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
# 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) $+ 

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
