The best way to answer this kind of question is to look at the source code.
You can find out exactly what files are being used to build your object by using the verbose keywork to the make and then take a look at what the code is doing. eric On Fri, Apr 17, 2009 at 6:30 PM, BAI LI <[email protected]> wrote: > Hi Michael, > Thanks for your reply.
