Thanks, Krzysztof.

This a valuable lesson for me. 

Last few days, I just want to report the bugs as quickly as I can.

And I only focus the bugs I found but not the patch compiling problem.

Yes, I admit this approach (way) is not serious and this is my fault, sorry again and sorry to waste your time.

From now on, I will not send any new patch commit before I compile the patch code.

Sorry for my behavior.
