Re: wxWidgets und vc++
Hi
Anscheinend weiss niemand bescheid, ich probiere es mal ein wenig komkreter zu umschreiben.
Ich habe die libs von wxwidgets erstellt mit vc++. nun habe ich ein eigenes Projekt erstellt und folgendes reingeschrieben:
#include "wx/wx.h"
class MyApp : public wxApp
{
public:
virtual bool OnInit();
};
DECLARE_APP(MyApp)
IMPLEMENT_APP(MyApp);
bool MyApp::OnInit()
{
wxFrame *frame = new wxFrame((wxFrame*) NULL, -1, "Hello World");
frame->CreateStatusBar();
frame->SetStatusText("Hello World");
frame->Show(TRUE);
SetTopWindow(frame);
return true;
}
Das kompilieren funktioniert 0 errors...
Aber das linken nicht. Bekomme immer folgende Fehlermeldungen:
--------------------Configuration: test - Win32 Debug--------------------

Weiss einer was bei den Settings im VC++ falsch ist damit ich das Projekt linken kann.
Vielen Dank
