Hi,
       When I study the  Extensible Kernel,I meet a problem,which described as follows:
I wish to create a C_Kernel for my C_Point2 class(all in the attachment), and I create a constructor initializer

for the C_point2 class which takes four parameters.the pronlem turns out as i wish to initialize the point. 

part of the code in the C_Kernel is:

          typedef   C_Point2  Point_2

      in main() I just call the constructor initializer 

         Point p(1.0f,2.0f,3,2)

then it turns out to wrong,complier says that the class has no constructor initializer that takes 4  parameters.

And i found the Point_2 is not the point which I defined in the C_Point2 ,But when i changed the code as  

        typedef C_Point2      Point.

Then the program go right. I wish to know why? May be my depict are not clear,a example has been attached

 in the  attachment and my complier is VS2008 in Win7. 

              

                                                                                                                                             Thank you!
