Re: Re: compile error about gateway

["Silver" <marco_hair@163.com>]

hi, Dirk:

  I am using base.14.8.2. I have seen those comments in gateVc.cc, making me puzzle is that I uncomment the line for base3.14.9, the compilation will pass for base3.14.8.2 on centOS5.2.
  I will have a look at your reply before. thanks a lot.
