hello!

i started the 3dBuzz GUI-Design VTM and i have some problems getting wxwidgets to run properly.

i use visual studio 2005 beta 2 with ms platform sdk (april 2005) and wxwidgets 2.5.3

when creating the libraries in wxwidgets i do get a lot of warnings (more than the guys in the VTM), but all 7 builds are successful.

when trying to compile my first project (of course the helloWorld :) ) i get some linking errors.

here is my code:


#include "wx/wx.h"

class HelloWorldApp : public wxApp
{
public:
virtual bool OnInit();
};

IMPLEMENT_APP(HelloWorldApp)

bool HelloWorldApp::OnInit()
{
wxFrame *frame = new wxFrame(NULL, -1, argv[0]);

frame->Show(TRUE);

SetTopWindow(frame);

return true;
}


and here are the errors i get:

just found something on the ms-sdk homepage:

If you are using Microsoft Visual C/C++®, run it at least once before installing the SDK. This will ensure that the environment variables are correctly configured

i did not run vc++ before installing the sdk. can this somehow cause these problems?

You forgot to link your code against the wx library. As such, all the WxWidgets symbols are failing. You need to specify either the library's .lib (if you want a static link) or .dll (a dynamic link) file for it. Usually, you will want a dynamic link.
You can add that in your project settings. If you are unsure, I'm pretty sure wxwidgets already comes with some vc projects, so check your settings against those.
