Re: gcc-3.2 can not locate stl containers (vector, map, ... etc)

Hi,

you have probably a problem with the namespace std. You have to use 
"std::vector" instead of "vector" or you can put at the beginning of the 
file: using namespace std;
, which avoids that you'll have to write always the prefix "std::"

This is the case for all STL (vectro, map, algorithm, ...) and for the 
iostream (cout, cerr, etc.) too.

I hope that helps you out,

Andres

p.d. the ISO C++ demands that the standard include file do not have the 
suffix .h, e.g. #include <vector> instead of #include <vector.h>
