Hi  

I am porting a project from VC 6 to VC .NET 2003. While compiling most of the files are giving errors as

 

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(29) : error C2143: syntax error : missing ';' before '('

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(29) : error C2226: syntax error : unexpected type 'size_t'

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(30) : error C2059: syntax error : ')'

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(29) : error C2365: 'new' : redefinition; previous definition was a 'member function'

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(29) : error C2491: 'new' : definition of dllimport data not allowed

c:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\include\xdebug(29) : error C2078: too many initializers

 

This is just a part of the errors I get. However, as you can see, all errors point to the same file ‘xdebug’.

Could anyone throw some light on this and help me?

 

Thanks and regards,

JJ

Hi jjbordoloi,
Make sure you're not using non-standard headers.
The following are non-standard headers, and are not part of the C++ standard, and therefore not portable.
#include <vector.h>
#include <list.h>
#inlcude <iostream.h>

The above headers work for  VC++ 6.0, because it supported them, but VC++ 7.x is more compliant with the C++ standard, and therefore it doesn't support these non-standard headers.

If you have the above headers listed in your code, you should convert them to extensionless headers.
#include <vector>
#include <list>
#inlcude <iostream>

The above headers are part of the C++ standard, and therefore portable to compliant C++ compilers like VC++ 7.x and 8.0


Cheers!

jjbordoloi,
If your code is not using non-standard headers, then please post the code that is giving you compile errors.

Hi David ,

Thank you for the reply. However, I have already done what you have suggested.
I have also used ‘Not Using Precompiled Headers’ option in the project settings but to no avail.

Here is the code as well.

#include "stdafx.h"
#include "superspn.h"
#include "superspn.ext"
#include "addpbk.h"
#include "terminal.h"
#include "adddirec.h"
#include "incflow.h"
#include "impactdl.h"
#include "engine.hpp"
#include "usage.h"

#ifdef _DEBUG
#undef THIS_FILE
static char BASED_CODE THIS_FILE[] = __FILE__;
#endif

/////////////////////////////////////////////////////////////////////////////
// CAddPBKDlg dialog

CAddPBKDlg::CAddPBKDlg(CWnd* pParent, const char *Acode)
                    :KeyDialog(CAddPBKDlg::IDD, pParent)
{
      Code = Acode;
      Code.MakeUpper();
      //{{AFX_DATA_INIT(CAddPBKDlg)
            // NOTE: the ClassWizard will add member initialization here
      //}}AFX_DATA_INIT
}

CAddPBKDlg::~CAddPBKDlg()
{
      if(pbkCB)
            delete pbkCB;
      if(pbkDirCB)
            delete pbkDirCB;
}

void CAddPBKDlg::DoDataExchange(CDataExchange* pDX)
{
      CDialog::DoDataExchange(pDX);
      //{{AFX_DATA_MAP(CAddPBKDlg)
            // NOTE: the ClassWizard will add DDX and DDV calls here
      //}}AFX_DATA_MAP
}


BEGIN_MESSAGE_MAP(CAddPBKDlg, CDialog)
      //{{AFX_MSG_MAP(CAddPBKDlg)
      ON_BN_CLICKED(IDSAVE, OnSaveButton)
      ON_CBN_SELCHANGE(IDC_TERM_DIRECTIONS_COMBO, OnSelchangeDirections)
      ON_CBN_SELCHANGE(IDC_TERM_BREAKS_COMBO, OnSelchangeBreaks)
      //}}AFX_MSG_MAP
END_MESSAGE_MAP()

/////////////////////////////////////////////////////////////////////////////
// CAddPBKDlg message handlers

KeyDialog::keyState CAddPBKDlg::IsNewKey(CustomControl *cntl)
{
      if(Code == cntl->GetValue())
            return OLD_KEY;
      return NEW_KEY;
}

void CAddPBKDlg::RestoreKey(CustomControl *cntl)
{
        cntl->SetValue(Code);
}

KeyDialog::errorCode CAddPBKDlg::UpdateKey(CustomControl *)
{
      EnablePBKGroup(FALSE);
      if(!Code.IsEmpty())
      {
            Code.MakeUpper();
            if(((CComboBox *)GetDlgItem(IDC_TERM_CODE_ALLOW_PBK))->FindStringExact(-1, Code) == CB_ERR)
                  return INVALID;
            else
                  ((CComboBox *)GetDlgItem(IDC_TERM_CODE_ALLOW_PBK))->SelectString(-1, Code);
            setClass(ControlWithId(IDC_TERM_CODE_ALLOW_PBK)->GetClass());
            database->addField(ControlWithId(IDC_TERM_CODE_ALLOW_PBK)->GetField(), Code);
            return OK;
      }
      return INCOMPLETE;
}

void CAddPBKDlg::setField(CustomControl *cntl)
{
      if(cntl->GetId() == IDC_TERM_CODE_ALLOW_PBK)
            Code = cntl->GetValue();
}

JJ

If you do that, then you need to remove "stdafx.h" from your code.

I have tried all the possible combinations -
"stdafx.h" with and without ‘Not Using Precompiled Headers’
and commenting out "stdafx.h" with both ‘Using/ Not Using Precompiled Headers’ options.

From my research, this can be related to the line

     #define new DEBUG_NEW

that is usually at the top of an MFC generated source file.   The standard pre-amble normally looks like this:

=-=-=-=--=-==-=-=-=-=-=-=-==
#include "stdafx.h"
#include ...etc...

#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
#endif
=-=-=-=--=-==-=-=-=-=-=-=-==

Since the source code you posted did not include that line, it would be worth a try to add it as shown.  Do a Clean and Rebuild.

where the author seems to think it relates to
    #include <fstream>
and
   using namespace std
