    namespace std

    okay i've posted about this topic before here he goes again...

    so here i am compiling a multi source program and i'm getting all these duplicate symbol from std, etc...

    it has something to do with using namespace std;
    in multiple files

    #include <iostream>

    using namespace std;

    so has anyone else had a problem with this before ?

    can you post the errors? maybe youare #including something more than once in your files? use ifdef for caution.

    i have no clue what your talking about, but try this (even though it's kinda redundant... )

    Code:
    #ifndef _iostream_h_std
    #define _iostream_h_std
    #include <iostream>
    using namespace std;
    #endif
    btw, it's just expanding on what axon said...

    the ifdefsare already int he include files

    are you compiling from a makefile? perhaps its recreating the object files more than one and overlaps? thats what the problem was for me
