[ns] Question about adding new queue type in ns2.1b6!

[Wu Wei <wuwei@sdp.ee.tsinghua.edu.cn>]

Hi,ns-users,

I asked this question several days ago,but no reply.I have to ask
twice,for
it's really urgent.
I met trouble when I tried to implement one queue type of mine.I
inherited a new queue class in c++ from
class Queue and implement of mine. Code compiled ok but when I tried to
test it,it complained as followed,
It seemed to complain that no unblock_on_resume_ variable,but I think it

has been declared and initialized
in class Queue,I inherited it from Queue.
Any hints are welcome.
Thanks
