编译使用Opencv的cpp文件

Question

所以我有一个使用OpenCV的.cpp文件。我在链接库方面遇到了一些问题，但我认为我的Makefile现在“更好”了。

生成文件：

CC=g++
#CC=gcc

# compile flags
CFLAGS=-g -Wall

# OpenCV Related
prefix=/usr/local/opencv

OCVFLAGS=-I${prefix}/include/opencv -I${prefix}/include
OCVLIBS=-L${prefix}/lib -lopencv_core -lopencv_highgui -lopencv_imgproc -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_flann -lopencv_objdetect -lopencv_calib3d


PROGRAM=extractDescriptorsToFile

OBJECTS=$(PROGRAM).o

program: $(OBJECTS)
    $(CC) $(OBJECTS) -o $(PROGRAM) $(OCVLIBS) -arch i386 

$(PROGRAM).o: $(PROGRAM).cpp
    $(CC) -c $(CFLAGS) $(OCVFLAGS) $(PROGRAM).cpp 

clean:
    rm -f *o
    rm -f $(PROGRAM)
    rm -f *~

然而，当我“make”时，会生成.o文件但是我收到此错误：

ld: warning: ignoring file extractDescriptorsToFile.o, file was built for unsupported file format which is not the architecture being linked (i386)
Undefined symbols for architecture i386:
  "_main", referenced from:
      start in crt1.10.6.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
make: *** [program] Error 1

这是一篇类似的帖子“Precompiled headers and compiling universal objects on OSX”，但我认为这不是我的问题吗？

任何帮助将不胜感激......？

我认为这个错误有时是由于没有main（）但我的文件确实...

删除“-arch i386”让我：
