Undefined references with wx-devcpp beta 6.3

[creator]

Hello,
I'm developing a project with wxWidgets.
I work mainly with Linux (wxWidgets 2.4.2, gcc 3.3).
But I had to recompile the project under windows.
So I installed the latest version of wx-devcpp, created the project file and
tried to compile but:

Code: Select all

#ifdef __GNUG__
	#pragma implementation "MHWizFrame.h"
#endif

#include <wx/wx.h>
//#include <wx/image.h>
#include "MHWizFrame.h"
#include "MHWizOrderPanel.h"
#include "MHWizMebelsPanel.h"
#include "MHWizMaterialsPanel.h"
/*

	EVT_MENU( MHWizFrame::MENU_PROGRAM_EXIT , MHWizFrame::OnExit)

	EVT_TOOL( MHWizFrame::TOOL_ORDER , MHWizFrame::OnOrderPanel)
END_EVENT_TABLE()
*/
bool panel_loaded;
extern bool materials_loaded;
extern bool mebels_loaded;
wxString Buf;

MHWizFrame::MHWizFrame(wxWindow* parent, int id, const wxString& title, const wxPoint& pos, const wxSize& size, long style):
    wxFrame(parent, id, title, pos, size, wxDEFAULT_FRAME_STYLE)
{
some more code

when the event table is commented i get:

Oh, and I removed wxWidgets 2.5.3 and then installed dev pak for 2.4.2
the same with both versions

Hi!
Have you used DECLARE_EVENT_TABLE() in you classes header file?

yes:

hmm, starnge
updated gcc and binutils to latest available from devpacks.org and
voiala, it compiles and links without problems.
Seems a bit strange to me.
After that updated wx to 2.5.3, but didn't have time to test.
Will post the rasults later:)
