[Insight-users] Re: Build problem

[Zhuang Song (Johnny)]

Hello Gavin,
Yeah, it works!! Sorry for the namespace mistake. It worked well before
even without specifying the std namespace, because I just copied it from
my old program. I tried it again in my another computer with older
version compiler, and it did work without specifying the std namespace.
Maybe the newer compiler is more strict on this. Anyway, I appreciate
your kind help.
