Used but not defined as type error

ChemicalBurn · 05-24-2005, 06:23 AM

I have this problem while compiling, and I can't seem to figure out why... I created a class Stats, eventually brought it down to a constructor and destructor to check where the error is from:

Code:

#ifndef STATS_H
#define STATS_H

#include <iostream.h>
#include <iomanip>

#include <GRAPH/Map.h>
#include <GRAPH/List.h>
#include <GRAPH/String.h>

#include "LSPEdgeType.h"
#include "IPNodeType.h"
#include "StructTypeDef.h"

using namespace GRAPH;
using namespace std;

/**
  *@author Johnny Ghibril
  */

class Stats {
  private:
    double valSimTime;
    int numConReq;

    List<LSPEdge>  EdgeList;
    List<LSPEdge>  BlockedEdgeList;
    List<int> ConnectionSignals;
    List<int> BlockedSignals;
    Map<int, String> SignalStrings;

  public:
    Stats();
    ~Stats();

};

#endif

and the cpp file contains nothing really...
But when I declare it in another class DMLRController in the header file I get this error:
DMLRControler.h:77: error: 'Stats' is used as a type, but is not defined as a type.
Although its fine in the cpp file of that class and in the main.
Any idea why this is happening?
Here's the code for the header file DMLRController.h:

Code:

#ifndef DMLRCONTROLER_H
#define DMLRCONTROLER_H

#include <CNCL/EventHandler.h>
#include <GRAPH/String.h>
#include <GRAPH/PriorityQueue.h>
#include <iostream>       
#include <GRAPH/Map.h>
#include <GRAPH/List.h>
#include <GRAPH/String.h>

#include "IPNodeType.h"
#include "LSPNodeType.h"
#include "LSPEdgeType.h"
#include "FindPath.h"
#include "Stats.h"

class NetworkState;
#include "NetworkState.h" 
#include "StructTypeDef.h"
/**
  *@author Johnny Ghibril
  */

using namespace GRAPH;
using namespace std;

class DMLRControler : public CNEventHandler  {
  private:    
    NetworkState * NetSt;
    IPNode IpNode;
    LSPEdge EdgeToReroute;
    LSPEdge waitingLspEdge;
    List<LSPEdge> WaitForRerouteList;
    static bool WithRerouting;
    Map<int,String> DebugMap;

    
    enum {	ST_READY,
            ST_WAITFORTARGET,
            ST_WAITFORREROUTESOURCE,
            ST_WAITFORREROUTETARGET
    };
    enum {DB_OK,DB_NOTOK};
       
    
  public:
    DMLRControler(){;};
    DMLRControler(NetworkState * netst, IPNode ipnode, String name);
    ~DMLRControler();

    virtual void event_handler(const CNEvent *ev);

    List<LSPEdge> FindRerouteConnections(LSPEdge lspedge);   
    
    void SetRerouteFlag(bool flag);

    void PrintDebugInfo(int state, int type, int debuginfo);

    Stats statisticObject;
    /// return statistics object
//    statistics GetStatisticObject(){return statisticObject;};
};

#endif

Thanks.

Check the errors above that one in the compiler output. If there was anything that could not be defined in the class, then the class will not be defined itself, therefore any attempt to instantiate it will fail. Check to make sure that 'List', 'LSPEdge', and 'String' can be instantiated with the include structure you have. If they can't then that is the problem. If they can be, then check for missing '}' in any files you haven't had a successful compile with before. Some errors will be a result of bugs in entirely different areas of your code (even points past where the error shows up), therefore try fixing compiler errors past that one also (if they can be fixed without fixing this one).

PS Or maybe just remove both of the ';' from

Code:

    DMLRControler(){;};

I have no compilation errors in the code. Everything runs fine. This class is simply to add some statistical output. Which is basically string generation, its probably the simplest class so far (Stats) And I've already been using the DMLRControler class for a while now and it hasnt generated any errors in runtime either.
I removed the `;´ from the DMLRControler(){;}; and left the DMLRControler(){} as well as DMLRControler(); and still the same error.
This is getting really frustrating because all the rest of the objects in the class are also objects in the project just like Stats. But its the only one the generates the error.
Any ideas?
