Dear members:

I have defined a simple static template class for coping a vector in to
another one if some condition hold for all elements, when I call it in
the following way Microsoft Visual C++ doesn't compile:

stdE::vectorOp<int,std::bind2nd(std::greater<int>,0)>::copy(in,out,index,

std::bind2nd(std::greater<int>(),0));

(see below for looking to output window after compiling)

a) I have checked also that for template function it works, for example,
when I use:


std::find_if(positiveVec.begin(),positiveVec.end(),std::bind2nd(std::greater<int>(),0));

b) And also if I define a positive object function ( particular case of
greater) it works, for example:

  stdE::vectorOp<int,stdE::isPositive<int>
>::copy(in,out,index,stdE::isPositive<int> ());


way?

Thank in advance,

David Leal
