I have code that goes like this:

#include <sstream>
#include <iostream>

Cartesian Cartesian::BuildFromString(const char* specString)
{
std::stringstream myStream(specString);
.
.
.
}

This fails to compile with the error, " 'stringstream' undeclared in namespace 'std' .


What's the problem here?

I see other posts on qnx.com to the effect that others are using std::stringstream with no problem, so why doesn't it 
work for ME?
