[Click] how to link use timer or pthread in my element?

[竺昱]

Yes, I have already put _timer.initialize(this) in the initialize
method of this element.
I think this initialize method is not called.
it still reports "void Timer::schedule_at(const Timestamp&): Assertion
`_router && initialized()' failed."

Could you tell me when the initialize method of an element will be called?
Thank you very much
