Re: Globals

This problem is really annoying, so here it is

testTrace.cpp:
--8<---------------cut here---------------start------------->8---
// -*- compile-command: "g++ testTrace.cpp Trace.cpp"-*-
#include<iostream>
#include "Globals.h"
#include "Trace.h"

using namespace std;

int main()
{
     GLOBALS::trace_length = 10;
     cout<< GLOBALS::trace_length<< endl;
     Trace t;

     return 0;
}
--8<---------------cut here---------------end--------------->8---

Trace.h
--8<---------------cut here---------------start------------->8---
#ifndef TRACE_H
#define TRACE_H

#include<map>
#include<vector>
#include "RingBuffer.h"
#include "PadNodeID.h"
#include "Globals.h"

class Trace
{
private:
     RingBuffer<PadNodeID> empty;
     std::map<PadNodeID, PadNodeID> trace;

public:
     Trace();
};

#endif /* TRACE_H */
--8<---------------cut here---------------end--------------->8---

Trace.cpp
--8<---------------cut here---------------start------------->8---
#include<iostream>
#include "Globals.h"
#include "Trace.h"
#include "PadNodeID.h"

Trace::Trace () : empty(GLOBALS::trace_length)
{
     std::cout<< GLOBALS::trace_length;
}
--8<---------------cut here---------------end--------------->8---

Globals.h
--8<---------------cut here---------------start------------->8---
#ifndef GLOBALS_H
#define GLOBALS_H

#include<iostream>
#include "Environment.h"
#include "Globals.h"

namespace GLOBALS
{
     static int num_landmarks;
     static int trace_length;
     static int history_size;
     static int distribution_size;
     static Environment *environment;
     // see why this error
     static ostream *out;
}

#endif /* GLOBALS_H */
--8<---------------cut here---------------end--------------->8---

The guards are there, so it should be actually included only once, BUT
the second time I print the variable in the constructor is ALWAYS 0!!

Anything else or a completely different approach I could follow?
