这是我的文件的目录
我写的makefile如下：
#VPATH=$(srcdir)(objdir)(header):.
src=$(wildcard $(srcdir)/*.cpp)
object=$(patsubst $(srcdir)/%.cpp,$(objdir)/%.o,$(src))
srcdir=./source
objdir=./object
hderdir=./header
CXX=g++
CXXFLAGS=-Wall -c -O3 -Iheader
a.out(objdir) $(object)
        $(CXX) $(object)
$(objdir):
        mkdir -p ./object
$(object)(src)
        $(CXX) $(CXXFLAGS) $< -o $@

ls(objdir)
        echo $(object)




#main.o:%o:%cpp
#        $(CXX) $(CXXFLAGS) $<
#Point.o:%o:%cpp
#        $(CXX) $(CXXFLAGS) $<
#Circle.o:%o:%cpp
#        $(CXX) $(CXXFLAGS) $<
#Cylinder.o:%o:%cpp
#        $(CXX) $(CXXFLAGS) $<
clean:
        $(RM) $(object)
        $(RM) a.out
        rmdir ./object



一共是两个版本，注释掉的部分是我把所有文件放在同一个目录下时写的，编译运行都通过了。
但是按照头文件和源文件分类放了之后，可以编译生成.o文件但是链接就不行了。
报错内容是找不到   运算符重载<<
如下：
g++ ./object/Circle.o ./object/Cylinder.o ./object/main.o ./object/Point.o

源文件没有问题，不知道我的makefile错在什么地方？请高手赐教。
