RE: Re: undefined Symbol ...wxNotebookBase

Hello together,

I'm a colleague of Patrick Wilhelm and supporting him on his work with wx.NET.
So I can reproduce his error on my System. We're using the latest version of wx.NET from 2003/07/14.

Today I could isolate the problem with the undefined Symbols of ...wxNotebookBase.
If I change the file notebook.cxx from 

  ...
  extern "C" WXEXPORT
  wxNotebook* wxNotebook_ctor()
  {
     return new _Notebook();
  }
  ...

to

  ...
  extern "C" WXEXPORT
  wxNotebook* wxNotebook_ctor()
  {
  #ifdef _WINDOWS
     return new _Notebook();
  #else
    return new wxNotebook();
  #endif
  }
  ...

I can run the samples without problems.

I do not understand why the line <return new _Notebook()>
s a problem, because it seems, that it has nothing to do with wxNotebookBase, but with this change everything works fine.

I tried to make changes in the class _Notebook and I removed everything than the class declaration:
  ...
  class _Notebook : public wxNotebook
  {
  }
  ...
  extern "C" WXEXPORT
  wxNotebook* wxNotebook_ctor()
  {
     return new _Notebook();
  }
  ...

But this did not work, too - the same error occured. Very crazy. The direct usage of wxNotebook works fine and using the derived class does not work. I have no idea why.
But perhaps it is a hint for someone of you, what's going wrong.


Kind Regards

Achim Breunig
