Having some frustrating linking problems. It's probably something simple and I'm just completely retarded.
Specs:OS: Windows XP
IDE: Code::Blocks
Compiler: MinGW32
Library: wxWidgets
I'm having this problem with the 'Hello World' sample project from the help files included with wxWidgets. I also tried a different 'Hello World' sample from the net for wxWidgets and get the same result.
This is my first time around with the IDE, Compiler, and wxWidgets, so I kind of expected this. I'm used to using VS for just about everything so I wanted to move away from it.
I'll paste the sample 'HW' code and the linker error code below:
HW Code:#include <iostream.h>
#include "wx/wx.h"
class MyApp: public wxApp {
virtual bool OnInit();};
class MyFrame: public wxFrame {
public:
MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size);
void OnQuit(wxCommandEvent& event);
void OnAbout(wxCommandEvent& event);
private:
DECLARE_EVENT_TABLE()};
enum {
ID_Quit = 1,
ID_About,};
BEGIN_EVENT_TABLE(MyFrame, wxFrame)
EVT_MENU(ID_Quit, MyFrame::OnQuit)
EVT_MENU(ID_About, MyFrame::OnAbout)
END_EVENT_TABLE()
IMPLEMENT_APP(MyApp)
bool MyApp::OnInit() {
MyFrame *frame = new MyFrame( "Hello World", wxPoint(50,50), wxSize(450,340) );
frame->Show( true );
SetTopWindow( frame );
return true;}
MyFrame::MyFrame(const wxString& title, const wxPoint& pos, const wxSize& size)
: wxFrame((wxFrame *)NULL, -1, title, pos, size) {
wxMenu *menuFile = new wxMenu;
menuFile->Append( ID_About, "&About..." );
menuFile->AppendSeparator();
menuFile->Append( ID_Quit, "E&xit" );
wxMenuBar *menuBar = new wxMenuBar;
menuBar->Append( menuFile, "&File" );
SetMenuBar( menuBar );
CreateStatusBar();
SetStatusText( "Welcome to wxWidgets!" );}
void MyFrame::OnQuit(wxCommandEvent& WXUNUSED(event)) {
Close( true );}
void MyFrame::OnAbout(wxCommandEvent& WXUNUSED(event)) {
wxMessageBox( "This is a wxWidgets' Hello world sample",
"About Hello World", wxOK | wxICON_INFORMATION );}

So you get the point. The list goes on to be about 3-4 times that size.
Go easy on me please
. I'm spoiled by VS .NET and I hate it. Plus I'm tired of working with MS platforms only.
I apologize if this isn't even Code::Blocks related. This is just really bugging me. Any info would be much appreciated. Thanks
