Why is wxCrafter Hello World program not working? [C++, wxWidgets] - c++

Question

I followed the wxCrafter Hello World tutorial: https://wiki.codelite.org/pmwiki.php/Main/WxCrafterHelloWorld
Building process shows no errors, however no dialog shows up when I click "Build->Run" in CodeLite 13, for some reason nothing happens :/
main.cpp:
#include <wx/app.h>
#include <wx/event.h>
#include "MainDialog.h"
#include <wx/image.h>
// Define the MainApp
class MainApp : public wxApp
{
public:
MainApp() {}
virtual ~MainApp() {}
virtual bool OnInit() {
// Add the common image handlers
wxImage::AddHandler( new wxPNGHandler );
wxImage::AddHandler( new wxJPEGHandler );
MainDialog mainDialog(NULL);
mainDialog.ShowModal();
return false;
}
};
DECLARE_APP(MainApp)
IMPLEMENT_APP(MainApp)

Answer 1

Something is wrong with either the C::L installation or the wxCrafter plugin.
If you did follow the referenced tutorial, it should create a wxButton object as a member of the dialog and bind the event handler to it.
Can you compile and run the minimal sample from the wxWidgets install?
